When such a driver is built as module and the module is loaded, the `load_module()` function taints the kernel to signal code of unknown quality is loaded, and produces a warning like this: [ 8.076352] rts5208: module is from the staging directory, the quality is unknown, you have been warned. The same behaviour is absent, however, when a staging driver is compiled as built-in on the kernel image, since loading it happens through initcalls and not through load_module(). This might prevent relevant information of being available on a bug report (i.e. on a panic log) among other possible problems. NOTES: - The patch is written in such a way that all non-staging drivers are kept the way they were, except for staging drivers built with `-DSTAGING_CODE`. - Since it changes some macros related to clang LTO as well, I tested it and it works properly in kernels compiled with both clang and gcc. - Some `checkpatch.pl` errors, warnings and checks (with `--strict`) are present. Some were already there, some I introduced but I think they're unavoidable. Some IMHO don=B4t make sense at all, I think they would apply for most regular macros but initcall macros are just way different. Signed-off-by: =C1gatha Isabelle Chris Moreira Guedes --- CHANGELOG v2: - Changed the way we hook into the initcalls as suggested by Uwe, and moved the logic from `include/linux/module.h` to `include/linux/init.h`. - Adjusted accordingly to work with both GCC and clang with `CONFIG_LTO_CLANG=3Dy`, since some init scripts required that. - Fixed the missing space pointed out by Dan & other minor string details. - Changed the subject, since it became somewhat more of an init thing than a staging thing. drivers/staging/Makefile | 2 ++ include/linux/init.h | 76 ++++++++++++++++++++++++++++++++++------ init/main.c | 20 +++++++++++ kernel/module/main.c | 4 +-- 4 files changed, 88 insertions(+), 14 deletions(-) diff --git a/drivers/staging/Makefile b/drivers/staging/Makefile index 5390879b5d1b..7cea13436426 100644 --- a/drivers/staging/Makefile +++ b/drivers/staging/Makefile @@ -1,6 +1,8 @@ # SPDX-License-Identifier: GPL-2.0 # Makefile for staging directory =20 +subdir-ccflags-y +=3D -DSTAGING_CODE + obj-y +=3D media/ obj-$(CONFIG_FB_OLPC_DCON) +=3D olpc_dcon/ obj-$(CONFIG_RTL8192E) +=3D rtl8192e/ diff --git a/include/linux/init.h b/include/linux/init.h index 58cef4c2e59a..c7afee978b42 100644 --- a/include/linux/init.h +++ b/include/linux/init.h @@ -188,6 +188,8 @@ extern struct module __this_module; =20 #ifndef __ASSEMBLY__ =20 +extern void staging_taint(const char *code_id, bool module); + /* * initcalls are now grouped by functionality into separate * subsections.

Because Bluetooth driver of kernel 5.11 added sending the LE_Read_Transmit_Power command in initialize phase, hci up fails due to the issue. Especially in USB i/f case, it would be difficult to download patch FW that includes its fix unless hci is up. The driver already contains infrastructure to apply the quirk for the issue, but currently it only supports DMI based matching. Add support to match by chip id and baseline FW version to detect CYW4373 ROM FW build in generic system.

Currentl= y the focus is on the CPU block stuff. I hope to get around to the DSA switch d= river eventually but this is a small start that lets me boot a mainline kernel = on the board I have.

The issue is because the connection code in virt_wifi does not check the SSID from user space (it only checks the BSSID), and virt_wifi will call cfg80211_connect_result() with WLAN_STATUS_SUCCESS even if the SSID is different from the one virt_wifi has advertised. Eventually cfg80211 won't be able to find the cfg80211_bss and generate the warning. Fixed it by checking the SSID (from user space) in the connection code.

Some of LoongArch processors support DVFS, their IOCSR.FEATURES has IOCSRF_FREQSCALE set. And they has a micro-core in the package called SMC (System Management Controller) to scale frequency, voltage, etc. V1 -> V2: 1, Use module_platform_driver() instead of module_init()/module_exit(); 2, Move the lock protection into do_service_request(); 3, Add light-weight hotplug support with help of online()/offline() callbacks; 4, Simplify loongson3_freq_data by removing cur_cpu_freq; 5, Remove unneeded cpu_online() checking. V2 -> V3: 1, Sort header files in alphabetical order; 2, Use devm_kzalloc() instead of kzalloc(); 3, Set to the default frequency at module exit and suspend; 4, Simplify loongson3_cpufreq_probe() and loongson3_cpufreq_target(); 5, Update and fix comments.

Please check above thread for motivation on why this should be changed. Some further old discussions here as well: https://patchwork.ozlabs.org/project/linux-ext4/patch/20180924215655.3676-20-krisman@collabora.co.uk/ I am not sure whether this is the right way to fix this, but I think I have considered all cases discussed in previous threads.

But this skips the check if the target is on a module because the module may not be loaded. To fix this issue, this patch checks the number of probe target symbols in a target module when the module is loaded. If the probe is not on the unique name symbols in the module, it will be rejected at that point.

How to reproduce ================ #include #include #include #include #define HUGEPAGE_SIZE (16 * 1024 * 1024) int main() { void *addr = mmap((void *)-1, HUGEPAGE_SIZE, PROT_READ | PROT_WRITE, MAP_SHARED | MAP_ANONYMOUS | MAP_HUGETLB, -1, 0); if (addr == MAP_FAILED) { perror("mmap"); exit(EXIT_FAILURE); } snprintf((char *)addr, HUGEPAGE_SIZE, "Hello, Huge Pages!"); printf("%s\n", (char *)addr); if (munmap(addr, HUGEPAGE_SIZE) == -1) { perror("munmap"); exit(EXIT_FAILURE); } return 0; } Result without fix ================== # cat /proc/meminfo |grep -i HugePages_Free HugePages_Free: 20 # ./test mmap: Permission denied # Result with fix =============== # cat /proc/meminfo |grep -i HugePages_Free HugePages_Free: 20 # ./test Hello, Huge Pages! # Reported-by Pavithra Prakash Signed-off-by: Donet Tom --- fs/hugetlbfs/inode.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/fs/hugetlbfs/inode.c b/fs/hugetlbfs/inode.c index 412f295acebe..428fd2f0e4c4 100644 --- a/fs/hugetlbfs/inode.c +++ b/fs/hugetlbfs/inode.c @@ -228,7 +228,7 @@ generic_hugetlb_get_unmapped_area(struct file *file, unsigned long addr, if (len & ~huge_page_mask(h)) return -EINVAL; - if (len > TASK_SIZE) + if (len > mmap_end - mmap_min_addr) return -ENOMEM; if (flags & MAP_FIXED) { @@ -240,7 +240,7 @@ generic_hugetlb_get_unmapped_area(struct file *file, unsigned long addr, if (addr) { addr = ALIGN(addr, huge_page_size(h)); vma = find_vma(mm, addr); - if (mmap_end - len >= addr && + if (mmap_end - len >= addr && addr >= mmap_min_addr && (!vma || addr + len <= vm_start_gap(vma))) return addr; } -- 2.43.5 .

The former implies #PF-based page allocation, and the latter implies the usage of SGX_IOC_ENCLAVE_REMOVE_PAGES ioctl. EDMM-based lazy allocation and MADV_DONTNEED semantics provide significant performance improvement for some workloads that run on Gramine. For example, a Java workload with a 16GB enclave size has approx. 57x improvement in total runtime. Thus, we consider it important to permit these optimizations in Gramine. However, we observed hangs of applications (Node.js, PyTorch, R, iperf, Blender, Nginx) when run on Gramine with EDMM, lazy allocation and MADV_DONTNEED features enabled. We wrote a trivial stress test to reproduce the hangs observed in real-world applications. The test stresses #PF-based page allocation and SGX_IOC_ENCLAVE_REMOVE_PAGES flows in the SGX driver: /* repeatedly touch different enclave pages at random and mix with * madvise(MADV_DONTNEED) to stress EAUG/EREMOVE flows */ static void* thread_func(void* arg) { size_t num_pages = 0xA000 / page_size; for (int i = 0; i < 5000; i++) { size_t page = get_random_ulong() % num_pages; char data = READ_ONCE(((char*)arg)[page * page_size]); page = get_random_ulong() % num_pages; madvise(arg + page * page_size, page_size, MADV_DONTNEED); } } addr = mmap(NULL, 0xA000, PROT_READ | PROT_WRITE, MAP_ANONYMOUS, -1, 0); pthread_t threads[16]; for (int i = 0; i < 16; i++) pthread_create(&threads[i], NULL, thread_func, addr); This test uncovers two data races in the SGX driver. The remaining patches describe and fix these races. I performed several stress tests to verify that there are no other data races (at least with the test program above): - On Icelake server with 128GB of PRM, without madvise(). This stresses the first data race. A Gramine SGX test suite running in the background for additional stressing. Result: 1,000 runs without hangs (result without the first bug fix: hangs every time). - On Icelake server with 128GB of PRM, with madvise(). This stresses the second data race. A Gramine SGX test suite running in the background for additional stressing. Result: 1,000 runs without hangs (result with the first bug fix but without the second bug fix: hangs approx. once in 50 runs). - On Icelake server with 4GB of PRM, with madvise(). This additionally stresses the enclave page swapping flows. Two Gramine SGX test suites running in the background for additional stressing of swapping (I observe 100% CPU utilization from ksgxd which confirms that swapping happens). Result: 1,000 runs without hangs. v3 -> v4: - Added a preparatory patch to split the SGX_ENCL_PAGE_BEING_RECLAIMED flag into two: SGX_ENCL_PAGE_BUSY and SGX_ENCL_PAGE_PCMD_BUSY (split suggested by Dave Hansen [2]) - No changes in the second patch (that fixes the first bug) - Trivial changes in the third patch (that fixes the second bug), now that we have a preparatory patch; plus expanded a comment (as suggested by Dave Hansen) v2 -> v3: - No changes in code itself - Improved commit message of the first patch (text suggested by Dave Hansen); kept the CPU1 vs CPU2 diagram (as all reviewers liked it) - No changes in the commit message of the second patch v1 -> v2: - No changes in code itself - Expanded cover letter - Added CPU1 vs CPU2 race scenarios in commit messages [1] https://github.com/gramineproject/gramine/pull/1513 [2] https://lore.kernel.org/all/1d405428-3847-4862-b146-dd57711c881e@intel.com/ v1: https://lore.kernel.org/all/20240429104330.3636113-3-dmitrii.kuvaiskii@intel.com/ v2: https://lore.kernel.org/all/20240515131240.1304824-1-dmitrii.kuvaiskii@intel.com/ v3: https://lore.kernel.org/all/20240517110631.3441817-1-dmitrii.kuvaiskii@intel.com/ Dmitrii Kuvaiskii (3): x86/sgx: Split SGX_ENCL_PAGE_BEING_RECLAIMED into two flags x86/sgx: Resolve EAUG race where losing thread returns SIGBUS x86/sgx: Resolve EREMOVE page vs EAUG page data race arch/x86/kernel/cpu/sgx/encl.c | 23 ++++++++++++----------- arch/x86/kernel/cpu/sgx/encl.h | 10 ++++++++-- arch/x86/kernel/cpu/sgx/ioctl.c | 7 +++++++ arch/x86/kernel/cpu/sgx/main.c | 4 ++-- 4 files changed, 29 insertions(+), 15 deletions(-) -- 2.43.0 .

For each OTSTx status, there is a recommended total flash current for all channels to prevent the flash module entering into higher thermal level. For example, the total flash current should be limited to 1000mA/500mA respectively when the HW reaches the OTST1/OTST2 thermal level.

Mvflash_4ch module thermal threshold level 2 configuration register offset is 0x78, not succeeding from thermal threshold level 1 register 0x7a.

I have analyzed this issue and here is what I found: When too many signals are sent to the RT task, the overhead becomes very high. The task cannot perform its job and as a consquenece the rt_runtime (0.95s) is not reached even after hundreds of seconds. This situation can be achieved by using POSIX Timers with very low interval. The problem scenario: 1. RTLIMIT_RTPRIO is changed to non-zero value. 2. Scheduler policy is changed to SCHED_FIFO or SCHED_RR. 3. Posix Timer is created with low interval - several nanoseconds. 4. The signaling overhead becomes very high, the RT task is scheduled but cannot reach rt_runtime (0.95s). As a consequenece there is no context switch with non-RT task even after hundreds of seconds. I have created a very simple solution by monitoring the number of signals and throttling the RT task when the number of signals is greater than or equal to 100. I am aware that this solution is very weak and cannot be applied as a long-term, proper solution. Could you help with finding more appropriate solution?

To easily reproduce this issue, you can follow the steps below: 1. format a device to exFAT and then mount (with a full disk erase) 2. dd if=/dev/zero of=/exfat_mount/test.img bs=1M count=8192 3. eject the device You may find that the dd process does not stop immediately and may continue for a long time. We compared it with the FAT, where FAT would prompt an EIO error and immediately stop the dd operation. The root cause of this issue is that when the exfat_inode contains the ALLOC_NO_FAT_CHAIN flag, exFAT does not need to access the disk to look up directory entries or the FAT table (whereas FAT would do) every time data is written. Instead, exFAT simply marks the buffer as dirty and returns, delegating the writeback operation to the writeback process. If the disk cannot be accessed at this time, the error will only be returned to the writeback process, and the original process will not receive the error, so it cannot be returned to the user side. Therefore, we think that when writing files with ALLOC_NO_FAT_CHAIN, it is necessary to continuously check the status of the disk. When the disk cannot be accessed normally, an error should be returned to stop the writing process.

Below is the rough estimation of total iterations done by these loops based on number of NUMA and CPUs. Total number of iterations: nCPU * 2 * Numa * mCPU Where: nCPU = total number of CPUs Numa = total number of NUMA nodes mCPU = mean value of total CPUs (e.g., 512 for 1024 total CPUs) For the system under test with 16 NUMA nodes and 1024 CPUs, this results in a substantial increase in the number of loop iterations during boot-up when NUMA is enabled: No NUMA = 1024*2*1*512 = 1,048,576 : Here refresh_zone_stat_thresholds takes around 224 ms total for all the CPUs in the system under test. 16 NUMA = 1024*2*16*512 = 16,777,216 : Here refresh_zone_stat_thresholds takes around 4.5 seconds total for all the CPUs in the system under test. Calling this for each CPU is expensive when there are large number of CPUs along with multiple NUMAs. Fix this by deferring refresh_zone_stat_thresholds to be called later at once when all the secondary CPUs are up. Also, register the DYN hooks to keep the existing hotplug functionality intact.

The programming usage on this device is the same as funnel. The software uses a funnel and a static replicator to implement the driver of this device. Since original funnels only support a single output connection and original replicator only support a single input connection, the code needs to be modified to support this new feature.

The controller is comprised of three main components that include a blit engine for 2D graphics accelerations, display controller for display output processing, as well as a command sequencer. Previous patch series attempts to do that can be found at: https://patchwork.freedesktop.org/series/84524/ This series addresses Maxime's comments on the previous one: a. Split the display controller into multiple internal devices. 1) List display engine, pixel engine, interrupt controller and more as the controller's child devices. 2) List display engine and pixel engine's processing units as their child devices. b. Add minimal feature support. Only support two display pipelines with primary planes with XR24 fb, backed by two fetchunits. No fetchunit dynamic allocation logic(to be done when necessary). c.

The CCU device works as a helper device physically connected to the TMC ETR device. --------------------------------------------------------- |ETR0| |ETR1| . \ / . . \ / . . \ / . . \ / . --------------------------------------------------- ETR0ATID0-ETR0ATID3 CCU ETR1ATID0-ETR1ATID3 --------------------------------------------------- Each ETR has four ATID registers with 128 bits long in total. e.g. ETR0ATID0-ETR0ATID3 registers are used by ETR0 device. Based on the trace id which is programed in CCU ATID register of specific ETR, trace data with that trace id can get into ETR's buffer while other trace data gets ignored. The number of CCU ATID registers depends on the number of defined TMC ETR devices. For example, two TMC ETR devices need eight ATID registers. ETR0 with ETR0ATID0-ETR0ATID3 and ETR1 with ETR1ATID0-ETRATID3. The significant challenge in enabling the data filter function is how to collect the trace ID of the source device. The introduction of trace_id callback function addresses this challenge. The callback function collects trace ID of the device and return it directly. The trace ID will be stored in the structure called cs_sink_data and transmitted to helper and sink devices. The cs_sink_data structure is created to address how to transmit parameters needs by coresight_enable_path/coresight_disbale_path functions. Here is an example of the struct cs_sink_data: struct cs_sink_data { struct perf_output_handle *handle; //used by perf mode struct coresight_device *sink; //used to retrieve atid_offset u32 traceid; //traceid needed by CCU }; The atid_offset mentioned before is the offset to ATID register in CCU device. Enabling the source device will configure one bit in the ATID register based on its trace ID. Disabling the source devices will reset the bit in the AITD register based on its trace ID. Useage: Enable: STM device with trace ID 5 and ETR0 is activated. Bitmap before the enablement: ETR0ATID0: 31..................543210 ========================== 0000000000000000000000...0 ========================== Bitmap after the enablement: 31..................543210 ========================== 0000000000000...0000100000 ========================== The bit 5 of the ETR0ATID0 register is configured to 1 when enabling the STM device. Disable: STM device with trace ID 5 and ETR0 is activated. Bitmap before the disablement: ETR0ATID0: 31................6543210 ========================= 000000000010111...0100000 ========================= Bitmap after the disablement ETR0ATID0: 31................6543210 ========================= 000000000010111...0000000 ========================= The bit 5 of the ETR0ATID0 register is reset to 0 when disabling the STM device. Previous discussion for V1: https://lore.kernel.org/lkml/20240618072726.3767974-1-quic_jiegan@quicinc.com/T/#t V1->V2: 1. Rename the device to Coresight Control Unit. 2. Introduce the trace_id function pointer to address the challeng how to properly collect the trace ID of the device. 3. Introduce a new way to define the qcom,ccu-atid-offset property in device tree. 4. Disabling the filter function blocked on acquiring the ATID-offset, which will be addressed in a separate patch once it’s ready.

These races involve concurrent VMOVP and VMAPP, the former happening on vcpu load, while the latter is triggered on the first device being MAPTI'd on a given ITS for this particular guest. The main issue is that we want to establish the affinity at VMAPP time, while vcpu_load wants to set the affinity where the vcpu actually runs. Lock ordering constraints mean that we can't lock the VPE on VMAPP, so things are modified without any lock. What could possibly go wrong? THe fix is a bit involved, and relies on 3 things: - Making sure that the initial affinity of a VPE is fixed at activate time, which is done early in the life of the vcpup, before it can run. - Add a per-VM lock that can be taken instead of the global vmovp_lock, paving the way for a more manageable lock order. - Take the per-VPE lock whenever modifying the VPE affinity, as expected everywhere else in the code. With that, VMAPP and VMOVP can now run concurrently and still lead to sensible results.

Enum arguments of non-syscall tracepoints can also be augmented, for instance timer:hrtimer_start and timer:hrtimer_init's 'mode' argument.

For example when ErasureCode [1] is used at the backend store, the optimum write performance is achieved when the WRITE request is aligned with the stripe size of ErasureCode. Otherwise a non-aligned WRITE request needs to be split at the stripe size boundary. It is quite costly to handle these split partial requests, as firstly the whole stripe to which the split partial request belongs needs to be read out, then overwrite the read stripe buffer with the request, and finally write the whole stripe back to the persistent storage. Thus the backend store can suffer severe performance degradation when WRITE requests can not fit into one stripe exactly. The write performance can be 10x slower when the request is 256KB in size given 4MB stripe size. Also there can be 50% performance degradation in theory if the request is not stripe boundary aligned. Besides, the conveyed test indicates that, the non-alignment issue becomes more severe when decreasing fuse's max_ratio, maybe partly because the background writeback now is more likely to run parallelly with the dirtier. fuse's max_ratio ratio of aligned WRITE requests ---------------- ------------------------------- 70 99.9% 40 74% 20 45% 10 20% With the patched version, which makes the alignment constraint opt-in when constructing WRITE requests, the ratio of aligned WRITE requests increases to 98% (previously 20%) when fuse's max_ratio is 10.

On those platforms, ACPI_ERST_GET_RECORD_ID returns ID 0x0 even if record store is empty. Reading record ID 0x0 on empty store fails with status code 0x4 (Record Store Empty). However, both "Record Store Empty" and "Record Not Found" are translated to -ENOENT, the reader cannot distinguish between them and tries to read the next id, which is again 0x0, and repeat that until it fills up the record cache with invalid entries.

There are 2 problems with this; 1. this is not what was implemented by the code and 2. this is not the desirable behavior. Desirable behavior is for khugepaged to be enabled when any PMD-sized THP is enabled, anon or file. (Note that file THP is still controlled by the top-level control so we must always consider that, as well as the PMD-size mTHP control for anon). khugepaged only supports collapsing to PMD-sized THP so there is no value in enabling it when PMD-sized THP is disabled. So let's change the code and documentation to reflect this policy. Further, per-size enabled control modification events were not previously forwarded to khugepaged to give it an opportunity to start or stop.

No regressions observed in mm selftests. When fixing this I also noticed that khugepaged doesn't get (and never has been) activated/deactivated by `shmem_enabled=`. I've concluded that this is definitely a (separate) bug. But I'm waiting for the conclusion of the conversation at [3] before fixing, so will send separately. Changes since v1 [1] ==================== - hugepage_pmd_enabled() now considers CONFIG_READ_ONLY_THP_FOR_FS as part of decision; means that for kernels without this config, khugepaged will not be started when only the top-level control is enabled. Changes since v2 [2] ==================== - Make hugepage_pmd_enabled() out-of-line static in khugepaged.c (per Andrew) - Refactor hugepage_pmd_enabled() for better readability (per Andrew) [1] https://lore.kernel.org/linux-mm/20240702144617.2291480-1-ryan.roberts@arm.com/ [2] https://lore.kernel.org/linux-mm/20240704091051.2411934-1-ryan.roberts@arm.com/ [3] https://lore.kernel.org/linux-mm/65c37315-2741-481f-b433-cec35ef1af35@arm.com/ Thanks, Ryan Documentation/admin-guide/mm/transhuge.rst | 11 ++++---- include/linux/huge_mm.h | 12 -------- mm/huge_memory.c | 7 +++++ mm/khugepaged.c | 33 +++++++++++++++++----- 4 files changed, 38 insertions(+), 25 deletions(-) diff --git a/Documentation/admin-guide/mm/transhuge.rst b/Documentation/admin-guide/mm/transhuge.rst index 709fe10b60f4..fc321d40b8ac 100644 --- a/Documentation/admin-guide/mm/transhuge.rst +++ b/Documentation/admin-guide/mm/transhuge.rst @@ -202,12 +202,11 @@ PMD-mappable transparent hugepage:: cat /sys/kernel/mm/transparent_hugepage/hpage_pmd_size -khugepaged will be automatically started when one or more hugepage -sizes are enabled (either by directly setting "always" or "madvise", -or by setting "inherit" while the top-level enabled is set to "always" -or "madvise"), and it'll be automatically shutdown when the last -hugepage size is disabled (either by directly setting "never", or by -setting "inherit" while the top-level enabled is set to "never"). +khugepaged will be automatically started when PMD-sized THP is enabled +(either of the per-size anon control or the top-level control are set +to "always" or "madvise"), and it'll be automatically shutdown when +PMD-sized THP is disabled (when both the per-size anon control and the +top-level control are "never") Khugepaged controls ------------------- diff --git a/include/linux/huge_mm.h b/include/linux/huge_mm.h index 4d155c7a4792..107da5c4eba4 100644 --- a/include/linux/huge_mm.h +++ b/include/linux/huge_mm.h @@ -128,18 +128,6 @@ static inline bool hugepage_global_always(void) (1< 0) { + int err; + + err = start_stop_khugepaged(); + if (err) + ret = err; + } return ret; } diff --git a/mm/khugepaged.c b/mm/khugepaged.c index 409f67a817f1..a5ec03ef8722 100644 --- a/mm/khugepaged.c +++ b/mm/khugepaged.c @@ -413,6 +413,26 @@ static inline int hpage_collapse_test_exit_or_disable(struct mm_struct *mm) test_bit(MMF_DISABLE_THP, &mm->flags); } +static bool hugepage_pmd_enabled(void) +{ + /* + * We cover both the anon and the file-backed case here; file-backed + * hugepages, when configured in, are determined by the global control. + * Anon pmd-sized hugepages are determined by the pmd-size control. + */ + if (IS_ENABLED(CONFIG_READ_ONLY_THP_FOR_FS) && + hugepage_global_enabled()) + return true; + if (test_bit(PMD_ORDER, &huge_anon_orders_always)) + return true; + if (test_bit(PMD_ORDER, &huge_anon_orders_madvise)) + return true; + if (test_bit(PMD_ORDER, &huge_anon_orders_inherit) && + hugepage_global_enabled()) + return true; + return false; +} + void __khugepaged_enter(struct mm_struct *mm) { struct khugepaged_mm_slot *mm_slot; @@ -449,7 +469,7 @@ void khugepaged_enter_vma(struct vm_area_struct *vma, unsigned long vm_flags) { if (!test_bit(MMF_VM_HUGEPAGE, &vma->vm_mm->flags) && - hugepage_flags_enabled()) { + hugepage_pmd_enabled()) { if (thp_vma_allowable_order(vma, vm_flags, TVA_ENFORCE_SYSFS, PMD_ORDER)) __khugepaged_enter(vma->vm_mm); @@ -2462,8 +2482,7 @@ static unsigned int khugepaged_scan_mm_slot(unsigned int pages, int *result, static int khugepaged_has_work(void) { - return !list_empty(&khugepaged_scan.mm_head) && - hugepage_flags_enabled(); + return !list_empty(&khugepaged_scan.mm_head) && hugepage_pmd_enabled(); } static int khugepaged_wait_event(void) @@ -2536,7 +2555,7 @@ static void khugepaged_wait_work(void) return; } - if (hugepage_flags_enabled()) + if (hugepage_pmd_enabled()) wait_event_freezable(khugepaged_wait, khugepaged_wait_event()); } @@ -2567,7 +2586,7 @@ static void set_recommended_min_free_kbytes(void) int nr_zones = 0; unsigned long recommended_min; - if (!hugepage_flags_enabled()) { + if (!hugepage_pmd_enabled()) { calculate_min_free_kbytes(); goto update_wmarks; } @@ -2617,7 +2636,7 @@ int start_stop_khugepaged(void) int err = 0; mutex_lock(&khugepaged_mutex); - if (hugepage_flags_enabled()) { + if (hugepage_pmd_enabled()) { if (!khugepaged_thread) khugepaged_thread = kthread_run(khugepaged, NULL, "khugepaged"); @@ -2643,7 +2662,7 @@ int start_stop_khugepaged(void) void khugepaged_min_free_kbytes_update(void) { mutex_lock(&khugepaged_mutex); - if (hugepage_flags_enabled() && khugepaged_thread) + if (hugepage_pmd_enabled() && khugepaged_thread) set_recommended_min_free_kbytes(); mutex_unlock(&khugepaged_mutex); } -- 2.43.0 .

So the PG_lru check in stable_page_flags() will miss this kind of isolated folios. Use folio_test_large_rmappable() instead to also include isolated folios. Since pagecache supports large folios and the introduction of mTHP, the semantics of KPF_THP have been expanded, now it indicates not only PMD-sized THP.

A replacement was developed and named to BU27034ANUC. (Note the added 'A' in the model name). The BU27034ANUC has several changes that make the old BU27034NUC driver unusable with it. I was told the old BU27034NUC should not be encountered anywhere. Hence, this series converts the rohm-bu27034.c to support the new BU27034ANUC instead of the obsoleted BU27034NUC. Additionally, the series adds a read-only entry for the HARDWAREGAIN to help understanding what part of the scale is contributed by the gain, and what by the integration time. This is useful when figuring out why some transitions =66rom one 'scale' to other are failing. Revision history: v1 =3D> v2: - Split the one large patch to patches 3 - 6 for easier review.

Some drivers had already been validating this themselves. As such, we can mostly drop that driver validation. nbd is problematic, as we cannot only change to just stop calling blk_validate_limits(). This is because the LBS is updated in a 2-stage process: a. update block size in the driver and validate b. update queue limits So if we stop validating the limits in a., there is a user-visible change in behaviour (as we stop rejecting invalid limits from the NBD_SET_BLKSIZE ioctl). So I left that untouched. This topic was originally mentioned in [0] and then again in [1] by Keith. I have also included a related virtio_blk change to deal with blk_size config fallback.

So to allow us to test these filesystems, let's add a module parameter to control the size of the simulated virtio-blk devices. The value is mapped directly to the `capacity` field of the virtio-blk configuration space, so it must be expressed in sector numbers of 512 bytes. The default value (0x40000) is the same as the previous value, so the behavior without setting `capacity` remains unchanged. Before this patch or with this patch without setting `capacity`: $ modprobe vdpa-sim-blk $ vdpa dev add mgmtdev vdpasim_blk name blk0 virtio_blk virtio6: 1/0/0 default/read/poll queues virtio_blk virtio6: [vdb] 262144 512-byte logical blocks (134 MB/128 MiB) After this patch: $ modprobe vdpa-sim-blk capacity=614400 $ vdpa dev add mgmtdev vdpasim_blk name blk0 virtio_blk virtio6: 1/0/0 default/read/poll queues virtio_blk virtio6: [vdb] 614400 512-byte logical blocks (315 MB/300 MiB) Signed-off-by: Stefano Garzarella --- drivers/vdpa/vdpa_sim/vdpa_sim_blk.c | 25 +++++++++++++------------ 1 file changed, 13 insertions(+), 12 deletions(-) diff --git a/drivers/vdpa/vdpa_sim/vdpa_sim_blk.c b/drivers/vdpa/vdpa_sim/vdpa_sim_blk.c index b137f3679343..18f390149836 100644 --- a/drivers/vdpa/vdpa_sim/vdpa_sim_blk.c +++ b/drivers/vdpa/vdpa_sim/vdpa_sim_blk.c @@ -33,7 +33,6 @@ (1ULL << VIRTIO_BLK_F_DISCARD) | \ (1ULL << VIRTIO_BLK_F_WRITE_ZEROES)) -#define VDPASIM_BLK_CAPACITY 0x40000 #define VDPASIM_BLK_SIZE_MAX 0x1000 #define VDPASIM_BLK_SEG_MAX 32 #define VDPASIM_BLK_DWZ_MAX_SECTORS UINT_MAX @@ -43,6 +42,10 @@ #define VDPASIM_BLK_AS_NUM 1 #define VDPASIM_BLK_GROUP_NUM 1 +static unsigned long capacity = 0x40000; +module_param(capacity, ulong, 0444); +MODULE_PARM_DESC(capacity, "virtio-blk device capacity (in 512-byte sectors)"); + struct vdpasim_blk { struct vdpasim vdpasim; void *buffer; @@ -79,10 +82,10 @@ static void vdpasim_blk_buffer_unlock(struct vdpasim_blk *blk) static bool vdpasim_blk_check_range(struct vdpasim *vdpasim, u64 start_sector, u64 num_sectors, u64 max_sectors) { - if (start_sector > VDPASIM_BLK_CAPACITY) { + if (start_sector > capacity) { dev_dbg(&vdpasim->vdpa.dev, - "starting sector exceeds the capacity - start: 0x%llx capacity: 0x%x\n", - start_sector, VDPASIM_BLK_CAPACITY); + "starting sector exceeds the capacity - start: 0x%llx capacity: 0x%lx\n", + start_sector, capacity); } if (num_sectors > max_sectors) { @@ -92,10 +95,10 @@ static bool vdpasim_blk_check_range(struct vdpasim *vdpasim, u64 start_sector, return false; } - if (num_sectors > VDPASIM_BLK_CAPACITY - start_sector) { + if (num_sectors > capacity - start_sector) { dev_dbg(&vdpasim->vdpa.dev, - "request exceeds the capacity - start: 0x%llx num: 0x%llx capacity: 0x%x\n", - start_sector, num_sectors, VDPASIM_BLK_CAPACITY); + "request exceeds the capacity - start: 0x%llx num: 0x%llx capacity: 0x%lx\n", + start_sector, num_sectors, capacity); return false; } @@ -369,7 +372,7 @@ static void vdpasim_blk_get_config(struct vdpasim *vdpasim, void *config) memset(config, 0, sizeof(struct virtio_blk_config)); - blk_config->capacity = cpu_to_vdpasim64(vdpasim, VDPASIM_BLK_CAPACITY); + blk_config->capacity = cpu_to_vdpasim64(vdpasim, capacity); blk_config->size_max = cpu_to_vdpasim32(vdpasim, VDPASIM_BLK_SIZE_MAX); blk_config->seg_max = cpu_to_vdpasim32(vdpasim, VDPASIM_BLK_SEG_MAX); blk_config->num_queues = cpu_to_vdpasim16(vdpasim, VDPASIM_BLK_VQ_NUM); @@ -437,8 +440,7 @@ static int vdpasim_blk_dev_add(struct vdpa_mgmt_dev *mdev, const char *name, if (blk->shared_backend) { blk->buffer = shared_buffer; } else { - blk->buffer = kvzalloc(VDPASIM_BLK_CAPACITY << SECTOR_SHIFT, - GFP_KERNEL); + blk->buffer = kvzalloc(capacity << SECTOR_SHIFT, GFP_KERNEL); if (!blk->buffer) { ret = -ENOMEM; goto put_dev; @@ -495,8 +497,7 @@ static int __init vdpasim_blk_init(void) goto parent_err; if (shared_backend) { - shared_buffer = kvzalloc(VDPASIM_BLK_CAPACITY << SECTOR_SHIFT, - GFP_KERNEL); + shared_buffer = kvzalloc(capacity << SECTOR_SHIFT, GFP_KERNEL); if (!shared_buffer) { ret = -ENOMEM; goto mgmt_dev_err; -- 2.45.2 .

[Ftrace] In order to prove that the soft lockup CPU spends too much time iterating vmap_nodes and flushing tlb when purging vm_area structures, the ftrace confirms the speculation (Some info is trimmed). kworker: funcgraph_entry: | drain_vmap_area_work() { kworker: funcgraph_entry: | mutex_lock() { kworker: funcgraph_entry: 1.092 us | __cond_resched(); kworker: funcgraph_exit: 3.306 us | } ... ... kworker: funcgraph_entry: | flush_tlb_kernel_range() { ... ... kworker: funcgraph_exit: # 7533.649 us | } ... ... kworker: funcgraph_entry: 2.344 us | mutex_unlock(); kworker: funcgraph_exit: $ 23871554 us | } The drain_vmap_area_work() spends over 23 seconds. There are 2805 flush_tlb_kernel_range() calls in this ftrace log. * One is called in __purge_vmap_area_lazy(). * Others are called in kasan_release_vmalloc(). 3. Extending the soft lockup time can work around the issue (For example, # echo 60 > /proc/sys/kernel/watchdog_thresh). This confirms the above-mentioned speculation: drain_vmap_area_work() spends too much time. Commit 72210662c5a2 ("mm: vmalloc: offload free_vmap_area_lock lock") employs an effective vmap node logic. However, current design iterates 128 vmap_nodes and flushes tlb by a single CPU if vmap_lazy_nr < 2 * lazy_max_pages(). When enabling kasan, this might trigger the soft lockup because additional tlb flushes of kasan vmalloc spend much more time if 128 vmap nodes have the available purge list. Fix the issue by adding preempt point in purge_vmap_node() when enabling kasan.

There are 2 changes in V16 compared to V15 : - In patch 4, the sfp_get_name() helper was moved around to better match the structure of the file. Russell, I've added a Suggested-by tag from you, as I used a description paragraph verbatim from your last review. - Patches 7 and 8 were reworked so that we don't report the phy id in the netlink command PHY_GET, as this is inconsistent between C22 and C45, and C45 wasn't even supported. All other patches are left unchanged from V15, besides a net-next rebase. As a remainder, here's what the PHY listings would look like : - eth0 has a 88x3310 acting as media converter, and an SFP module with an embedded 88e1111 PHY - eth2 has a 88e1510 PHY # ethtool --show-phys * PHY for eth0: PHY index: 1 Driver name: mv88x3310 PHY device name: f212a600.mdio-mii:00 Downstream SFP bus name: sfp-eth0 Upstream type: MAC PHY for eth0: PHY index: 2 Driver name: Marvell 88E1111 PHY device name: i2c:sfp-eth0:16 Upstream type: PHY Upstream PHY index: 1 Upstream SFP name: sfp-eth0 PHY for eth2: PHY index: 1 Driver name: Marvell 88E1510 PHY device name: f212a200.mdio-mii:00 Upstream type: MAC Ethtool patches : https://github.com/minimaxwell/ethtool/tree/mc/topo-v16 Link to V15: https://lore.kernel.org/netdev/20240703140806.271938-1-maxime.chevallier@bootlin.com/ Link to V14: https://lore.kernel.org/netdev/20240701131801.1227740-1-maxime.chevallier@bootlin.com/ Link to V13: https://lore.kernel.org/netdev/20240607071836.911403-1-maxime.chevallier@bootlin.com/ Link to v12: https://lore.kernel.org/netdev/20240605124920.720690-1-maxime.chevallier@bootlin.com/ Link to v11: https://lore.kernel.org/netdev/20240404093004.2552221-1-maxime.chevallier@bootlin.com/ Link to V10: https://lore.kernel.org/netdev/20240304151011.1610175-1-maxime.chevallier@bootlin.com/ Link to V9: https://lore.kernel.org/netdev/20240228114728.51861-1-maxime.chevallier@bootlin.com/ Link to V8: https://lore.kernel.org/netdev/20240220184217.3689988-1-maxime.chevallier@bootlin.com/ Link to V7: https://lore.kernel.org/netdev/20240213150431.1796171-1-maxime.chevallier@bootlin.com/ Link to V6: https://lore.kernel.org/netdev/20240126183851.2081418-1-maxime.chevallier@bootlin.com/ Link to V5: https://lore.kernel.org/netdev/20231221180047.1924733-1-maxime.chevallier@bootlin.com/ Link to V4: https://lore.kernel.org/netdev/20231215171237.1152563-1-maxime.chevallier@bootlin.com/ Link to V3: https://lore.kernel.org/netdev/20231201163704.1306431-1-maxime.chevallier@bootlin.com/ Link to V2: https://lore.kernel.org/netdev/20231117162323.626979-1-maxime.chevallier@bootlin.com/ Link to V1: https://lore.kernel.org/netdev/20230907092407.647139-1-maxime.chevallier@bootlin.com/ More discussions on specific issues that happened in 6.9-rc: https://lore.kernel.org/netdev/20240412104615.3779632-1-maxime.chevallier@bootlin.com/ https://lore.kernel.org/netdev/20240429131008.439231-1-maxime.chevallier@bootlin.com/ https://lore.kernel.org/netdev/20240507102822.2023826-1-maxime.chevallier@bootlin.com/ Maxime Chevallier (14): net: phy: Introduce ethernet link topology representation net: sfp: pass the phy_device when disconnecting an sfp module's PHY net: phy: add helpers to handle sfp phy connect/disconnect net: sfp: Add helper to return the SFP bus name net: ethtool: Allow passing a phy index for some commands netlink: specs: add phy-index as a header parameter net: ethtool: Introduce a command to list PHYs on an interface netlink: specs: add ethnl PHY_GET command set net: ethtool: plca: Target the command to the requested PHY net: ethtool: pse-pd: Target the command to the requested PHY net: ethtool: cable-test: Target the command to the requested PHY net: ethtool: strset: Remove unnecessary check on genl_info net: ethtool: strset: Allow querying phy stats by index Documentation: networking: document phy_link_topology Documentation/netlink/specs/ethtool.yaml | 58 ++++ Documentation/networking/ethtool-netlink.rst | 51 +++ Documentation/networking/index.rst | 1 + .../networking/phy-link-topology.rst | 121 +++++++ MAINTAINERS | 1 + drivers/net/phy/Makefile | 2 +- drivers/net/phy/marvell-88x2222.c | 2 + drivers/net/phy/marvell.c | 2 + drivers/net/phy/marvell10g.c | 2 + drivers/net/phy/phy_device.c | 48 +++ drivers/net/phy/phy_link_topology.c | 105 ++++++ drivers/net/phy/phylink.c | 3 +- drivers/net/phy/qcom/at803x.c | 2 + drivers/net/phy/qcom/qca807x.c | 2 + drivers/net/phy/sfp-bus.c | 26 +- include/linux/netdevice.h | 4 +- include/linux/phy.h | 6 + include/linux/phy_link_topology.h | 82 +++++ include/linux/sfp.h | 8 +- include/uapi/linux/ethtool.h | 16 + include/uapi/linux/ethtool_netlink.h | 20 ++ net/core/dev.c | 15 + net/ethtool/Makefile | 3 +- net/ethtool/cabletest.c | 35 +- net/ethtool/netlink.c | 66 +++- net/ethtool/netlink.h | 33 ++ net/ethtool/phy.c | 308 ++++++++++++++++++ net/ethtool/plca.c | 30 +- net/ethtool/pse-pd.c | 30 +- net/ethtool/strset.c | 27 +- 30 files changed, 1057 insertions(+), 52 deletions(-) create mode 100644 Documentation/networking/phy-link-topology.rst create mode 100644 drivers/net/phy/phy_link_topology.c create mode 100644 include/linux/phy_link_topology.h create mode 100644 net/ethtool/phy.c -- 2.45.1 .

I have defined the new FLOW_DIS_F_* and TCA_FLOWER_KEY_FLAGS_* flags to co-exist with the existing flags, so the meaning of the flags field in struct flow_dissector_key_control is not depending on the context it is used in. If we run out of bits then we can always split them up later, if we really want to.

Which means that the users need to double cast the provided "value" as this is not a struct bpf_wq *.

The NXP i.MX secure enclaves hardware interface kernel driver, is specifically targeted for use between application core and NXP secure-enclave(s) HW. It allows to send/receive messages to/from the secure-enclave. Patch-set adds the kernel driver for communication interface to secure-enclave, for exchanging messages with NXP secure enclave HW IP(s) like EdgeLock Enclave, both from: - User-Space Applications via character driver. - Kernel-space, used by kernel management layers like DM-Crypt.

It is a prerequisite for enabling IRQ_WORK for MIPS. It has been tested on MIPS Boston I6500, malta CoreFPGA3 47K MT/ interAPtiv MPF, Loongson-2K, Cavium CN7130 (EdgeRouter 4), and an unannounced interaptiv UP MT platform with EIC. I don't really know broadcom platforms and SGI platforms well so changes to those platforms are kept minimal (no functional change). Please review.

I'm pleased to announce the v6.10-rc6-rt11 patch set. Changes since v6.10-rc6-rt10: - Update the series to fix "perf test sigtrap" to v5. - As a follow-up to the net/BH series: - Add an optimisation to lazy initialize the flush lists. - Initialize the BPF context within the tun driver and others using the generic-XDP to avoid crash. - Add a check to the seg6_state/ BPF code to only use it within the "expected" call path. Known issues None. The delta patch against v6.10-rc6-rt10 is appended below and can be found here: https://cdn.kernel.org/pub/linux/kernel/projects/rt/6.10/incr/patch-6.10-rc6-rt10-rt11.patch.xz You can get this release via the git tree at: https://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git v6.10-rc6-rt11 The RT patch against v6.10-rc6 can be found here: https://cdn.kernel.org/pub/linux/kernel/projects/rt/6.10/older/patch-6.10-rc6-rt11.patch.xz The split quilt queue is available at: https://cdn.kernel.org/pub/linux/kernel/projects/rt/6.10/older/patches-6.10-rc6-rt11.tar.xz Sebastian diff --git a/drivers/net/tun.c b/drivers/net/tun.c index 9254bca2813dc..9b24861464bc6 100644 --- a/drivers/net/tun.c +++ b/drivers/net/tun.c @@ -1661,6 +1661,7 @@ static struct sk_buff *tun_build_skb(struct tun_struct *tun, int len, int *skb_xdp) { struct page_frag *alloc_frag = ¤t->task_frag;

Although they work I am not 100% sure of their benefit. Especially the last patch which enables turning on NUMA balancing with tmpfs. Second one at least makes the flag handling a bit more robust in the sense that it can prevent future mistakes. Comments and opinions are welcome!

The stack assumed that PHY time stamping is always preferred, but some MAC/PHY combinations were buggy. This series updates the default MAC/PHY default timestamping and aims to allow the user to select the desired hwtstamp provider administratively. Changes in v16: - Add a new patch to separate tsinfo into a new tsconfig command to get and set the hwtstamp config. - Used call_rcu() instead of synchronize_rcu() to free the hwtstamp_provider - Moved net core changes of patch 12 directly to patch 8. - Link to v15: https://lore.kernel.org/r/20240612-feature_ptp_netnext-v15-0-b2a086257b63@bootlin.com Changes in v15: - Fix uninitialized ethtool_ts_info structure. - Link to v14: https://lore.kernel.org/r/20240604-feature_ptp_netnext-v14-0-77b6f6efea40@bootlin.com Changes in v14: - Add back an EXPORT_SYMBOL() missing. - Link to v13: https://lore.kernel.org/r/20240529-feature_ptp_netnext-v13-0-6eda4d40fa4f@bootlin.com Changes in v13: - Add PTP builtin code to fix build errors when building PTP as a module. - Fix error spotted by smatch and sparse. - Link to v12: https://lore.kernel.org/r/20240430-feature_ptp_netnext-v12-0-2c5f24b6a914@bootlin.com Changes in v12: - Add missing return description in the kdoc. - Fix few nit. - Link to v11: https://lore.kernel.org/r/20240422-feature_ptp_netnext-v11-0-f14441f2a1d8@bootlin.com Changes in v11: - Add netlink examples. - Remove a change of my out of tree marvell_ptp patch in the patch series. - Remove useless extern. - Link to v10: https://lore.kernel.org/r/20240409-feature_ptp_netnext-v10-0-0fa2ea5c89a9@bootlin.com Changes in v10: - Move declarations to net/core/dev.h instead of netdevice.h - Add netlink documentation. - Add ETHTOOL_A_TSINFO_GHWTSTAMP netlink attributes instead of a bit in ETHTOOL_A_TSINFO_TIMESTAMPING bitset. - Send "Move from simple ida to xarray" patch standalone. - Add tsinfo ntf command. - Add rcu_lock protection mechanism to avoid memory leak. - Fixed doc and kdoc issue. - Link to v9: https://lore.kernel.org/r/20240226-feature_ptp_netnext-v9-0-455611549f21@bootlin.com Changes in v9: - Remove the RFC prefix. - Correct few NIT fixes. - Link to v8: https://lore.kernel.org/r/20240216-feature_ptp_netnext-v8-0-510f42f444fb@bootlin.com Changes in v8: - Drop the 6 first patch as they are now merged. - Change the full implementation to not be based on the hwtstamp layer (MAC/PHY) but on the hwtstamp provider which mean a ptp clock and a phc qualifier. - Made some patch to prepare the new implementation. - Expand netlink tsinfo instead of a new ts command for new hwtstamp configuration uAPI and for dumping tsinfo of specific hwtstamp provider. - Link to v7: https://lore.kernel.org/r/20231114-feature_ptp_netnext-v7-0-472e77951e40@bootlin.com Changes in v7: - Fix a temporary build error. - Link to v6: https://lore.kernel.org/r/20231019-feature_ptp_netnext-v6-0-71affc27b0e5@bootlin.com Changes in v6: - Few fixes from the reviews. - Replace the allowlist to default_timestamp flag to know which phy is using old API behavior. - Rename the timestamping layer enum values. - Move to a simple enum instead of the mix between enum and bitfield. - Update ts_info and ts-set in software timestamping case. Changes in v5: - Update to ndo_hwstamp_get/set. This bring several new patches. - Add few patches to make the glue. - Convert macb to ndo_hwstamp_get/set. - Add netlink specs description of new ethtool commands. - Removed netdev notifier. - Split the patches that expose the timestamping to userspace to separate the core and ethtool development. - Add description of software timestamping. - Convert PHYs hwtstamp callback to use kernel_hwtstamp_config. Changes in v4: - Move on to ethtool netlink instead of ioctl. - Add a netdev notifier to allow packet trapping by the MAC in case of PHY time stamping. - Add a PHY whitelist to not break the old PHY default time-stamping preference API. Changes in v3: - Expose the PTP choice to ethtool instead of sysfs. You can test it with the ethtool source on branch feature_ptp of: https://github.com/kmaincent/ethtool - Added a devicetree binding to select the preferred timestamp. Changes in v2: - Move selected_timestamping_layer variable of the concerned patch. - Use sysfs_streq instead of strmcmp. - Use the PHY timestamp only if available.

This can happen i.e. on device-replace. Patch 2 splits a stripe extent on partial delete of a stripe. Patch 3 adds selftests for the stripe-tree delete code, these selftests can and will be extended to cover insert and get as well. Patch 4 fixes a deadlock between scrub and device replace when RST is used. Patch 5 get's rid of the pointless tree dump in case we're not finding an RST entry. Patch 6 is a prep-patch form #7 and renames btrfs_io_stripe::is_scrub to commit_root. Patch 7 changes the read code so we're looking at the commit_root for relocation as well. --- Changes in v4: - Addressed Josef's comments - Added patches 6 & 7 - Link to v3: https://lore.kernel.org/r/20240701-b4-rst-updates-v3-0-e0437e1e04a6@kernel.org Changes in v3: - Drop on-disk format change as it's in for-next - Add patches 4 & 5 - Link to v2: https://lore.kernel.org/r/20240619-b4-rst-updates-v2-0-89c34d0d5298@kernel.org Changes in v2: - Added selftests for delete code - Link to v1: https://lore.kernel.org/r/20240610-b4-rst-updates-v1-0-179c1eec08f2@kernel.org --- Johannes Thumshirn (7): btrfs: replace stripe extents btrfs: rst: don't print tree dump in case lookup fails btrfs: split RAID stripes on deletion btrfs: stripe-tree: add selftests btrfs: don't hold dev_replace rwsem over whole of btrfs_map_block btrfs: rename brtfs_io_stripe::is_scrub to commit_root btrfs: stripe-tree: also look at commit root on relocation fs/btrfs/Makefile | 3 +- fs/btrfs/bio.c | 3 +- fs/btrfs/ctree.c | 1 + fs/btrfs/raid-stripe-tree.c | 145 +++++++++++--- fs/btrfs/raid-stripe-tree.h | 5 + fs/btrfs/scrub.c | 2 +- fs/btrfs/tests/btrfs-tests.c | 3 + fs/btrfs/tests/btrfs-tests.h | 1 + fs/btrfs/tests/raid-stripe-tree-tests.c | 322 ++++++++++++++++++++++++++++++++ fs/btrfs/volumes.c | 28 +-- fs/btrfs/volumes.h | 2 +- 11 files changed, 470 insertions(+), 45 deletions(-) --- base-commit: 3caaac6559396d9e668deb10345b7f3bb45f6ba9 change-id: 20240610-b4-rst-updates-d0aa696b9d5a Best regards, -- Johannes Thumshirn .

That series has got too big and also has a dependency on the core block atomic writes support, which has now been queued for 6.11 in Jens' block tree [1]. The actual forcealign patches are the same in this series, modulo an attempt for a fix in xfs_bunmapi_align(). Why forcealign? In some scenarios to may be required to guarantee extent alignment and granularity. For example, for atomic writes, the maximum atomic write unit size would be limited at the extent alignment and granularity, guaranteeing that an atomic write would not span data present in multiple extents. forcealign may be useful as a performance tuning optimization in other scenarios. Early development xfsprogs support is at: https://github.com/johnpgarry/xfsprogs-dev/commits/atomic-writes/ Differences to v1: - Add Darricks RB tags (thanks) - Disallow mount for forcealign and RT - Disallow cp --reflink from forcealign inode - Comments improvements (Darrick) - Coding style improvements (Darrick) - Fix xfs_inode_alloc_unitsize() (Darrick) Baseline: xfs/for-next @ 3ba3ab1f6719 ("xfs: enable FITRIM on the realtime device") [0] https://lore.kernel.org/linux-xfs/20240607143919.2622319-1-john.g.garry@oracle.com/ [1] https://lore.kernel.org/linux-block/20240620125359.2684798-1-john.g.garry@oracle.com/ Darrick J.

This also prevents some implemented counters from being reported. * A build fix for the vector sigreturn selftest on clang. * A fix to ftrace, which now requires the previously optional index argument to ftrace_graph_ret_addr(). * A fix to avoid deadlocking if kexec crash handling triggers in an interrupt context. ---------------------------------------------------------------- Atish Patra (1): drivers/perf: riscv: Do not update the event data if uptodate Charlie Jenkins (2): documentation: Fix riscv cmodx example riscv: selftests: Fix vsetivli args for clang Palmer Dabbelt (1): Merge patch series "Assorted fixes in RISC-V PMU driver" Puranjay Mohan (1): riscv: stacktrace: fix usage of ftrace_graph_ret_addr() Samuel Holland (2): drivers/perf: riscv: Reset the counter to hpmevent mapping while starting cpus perf: RISC-V: Check standard event availability Song Shuai (1): riscv: kexec: Avoid deadlock in kexec crash path Documentation/arch/riscv/cmodx.rst | 4 +- arch/riscv/kernel/machine_kexec.c | 10 +---- arch/riscv/kernel/stacktrace.c | 3 +- arch/riscv/kvm/vcpu_pmu.c | 2 +- drivers/perf/riscv_pmu.c | 2 +- drivers/perf/riscv_pmu_sbi.c | 44 ++++++++++++++++++++-- .../testing/selftests/riscv/sigreturn/sigreturn.c | 2 +- 7 files changed, 49 insertions(+), 18 deletions(-) .

Currently IDXD driver just prints an error message in the interrupt handler. A better way to handle the interrupt is to do Function Level Reset (FLR) and recover the device's hardware and software configurations to its previous working state. The device and software can continue to run after the interrupt. This series enables this FLR handling for IDXD device whose WQs are all user type. FLR handling for IDXD device whose WQs are kernel type will be implemented in a future series.

Changes since v4: 1) Subject line on patch #2/3: s/mm/vDSO/ 2) Added Muhammad's review tag. Changes since v3: 1. Rebased onto Linux 6.10-rc6+. Cover letter for v3: Jason A. Donenfeld, I've added you because I ended up looking through your latest "implement getrandom() in vDSO" series [1], which also touches this Makefile, so just a heads up about upcoming (minor) merge conflicts. Changes since v2: 1. Added two patches, both of which apply solely to the Makefile. These provide a smaller, cleaner, and more accurate Makefile. 2. Added Reviewed-by and Tested-by tags for the original patch, which fixes all of the clang errors and warnings for this selftest. 3. Removed an obsolete blurb from the commit description of the original patch, now that Valentin Obst LLVM build fix has been merged. thanks, John Hubbard NVIDIA John Hubbard (3): selftests/vDSO: fix clang build errors and warnings selftests/vDSO: remove partially duplicated "all:" target in Makefile selftests/vDSO: remove duplicate compiler invocations from Makefile tools/testing/selftests/vDSO/Makefile | 29 ++++++++----------- tools/testing/selftests/vDSO/parse_vdso.c | 16 ++++++---- .../selftests/vDSO/vdso_standalone_test_x86.c | 18 ++++++++++-- 3 files changed, 39 insertions(+), 24 deletions(-) base-commit: d270dd21bee023ab627f34cfb77a9b89a688492a -- 2.40.1 .
