Subject: [GIT PULL] Compute Express Link (CXL) for 6.12 From: Dave Jiang To: Linus Torvalds Cc: "linux-cxl@vger.kernel.org" , Dan Williams , Jonathan Cameron , Davidlohr Bueso , Alison Schofield , Vishal Verma , Ira Weiny Date: Fri, 27 Sep 2024 07:02:57 -0700 Hi Linus, please pull from: git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl.git cxl-for-6.12 ...to receive updates for CXL subsystem. Changes contain a patch series to address HDM decoder initialization from DVSEC ranges, a patch series that refactors the code related to cxl mailboxes to be independent of the memory devices, a patch series that adds support for shared upstream link access_coordinate calculation, as well as a change to remove locking from memory notifier callback. In addition, a number of misc cleanups and refactoring of the code are also included. These have all appeared in -next for a few days with no reported issues. --- The following changes since commit 431c1646e1f86b949fa3685efc50b660a364c2b6: Linux 6.11-rc6 (2024-09-01 19:46:02 +1200) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl.git cxl-for-6.12 for you to fetch changes up to 2c70677dabb5e326467160e28915b804b925b53b: cxl: Add documentation to explain the shared link bandwidth calculation (2024-09-22 21:29:08 -0700) ---------------------------------------------------------------- cxl changes for v6.12 Misc cleanups: - Convert devm_cxl_add_root() to return using ERR_CAST(). - cxl_test use dev_is_platform() instead of open coding. - Remove duplicate include of header core.h in core/cdat.c. - use scoped resource management to drop put_device() for cxl_port - Use scoped_guard to drop device_lock() for cxl_port - Refactor __devm_cxl_add_port() to drop gotos - Rename cxl_setup_parent_dport to cxl_dport_init_aer and cxl_dport_map_regs() to cxl_dport_map_ras(). - Refactor cxl_dport_init_aer() to be more concise. - Remove duplicate host_bridge->native_aer checking in cxl_dport_init_ras_reporting(). - Fix comment for cxl_query_cmd() Series to address HDM decoder initialization from DVSEC ranges: - Only register non-zero DVSEC ranges. - Remove duplicate implementation of waiting for memory_info_valid. - Simplify the checking of mem_enabled in cxl_hdm_decode_init(). Remove locking from memory notifier callback Series that refactors the code related to cxl mailboxes to be independent of the memory devices - Move cxl headers in include/linux/ to include/cxl. - Move all mailbox related data to 'struct cxl_mailbox'. - Refactor mailbox APIs with 'struct cxl_mailbox' as input instead of memory device state. Series that adds support for shared upstream link access_coordinate calculation for configurations that have multiple targets under a switch or a root port where the aggregated bandwidth can be greater than the upstream link of the switch/RP upstream link. - Preserve the CDAT access_coordinate from an endpoint - Add the support for shared upstream link access_coordinate calculation - Add documentation to explain how the calculations are done. ---------------------------------------------------------------- Dave Jiang (7): cxl: move cxl headers to new include/cxl/ directory cxl: Move mailbox related bits to the same context cxl: Convert cxl_internal_send_cmd() to use 'struct cxl_mailbox' as input cxl: Fix comment regarding cxl_query_cmd() return data cxl: Preserve the CDAT access_coordinate for an endpoint cxl: Calculate region bandwidth of targets with shared upstream link cxl: Add documentation to explain the shared link bandwidth calculation Hongbo Li (1): cxl: Remove duplicate included header file core.h Ira Weiny (1): cxl/region: Remove lock from memory notifier callback Kunwu Chan (1): tools/testing/cxl: Use dev_is_platform() Li Ming (6): cxl/port: Use __free() to drop put_device() for cxl_port cxl/port: Use scoped_guard()/guard() to drop device_lock() for cxl_port cxl/port: Refactor __devm_cxl_add_port() to drop goto pattern cxl/pci: Rename cxl_setup_parent_dport() and cxl_dport_map_regs() cxl/pci: cxl_dport_map_rch_aer() cleanup cxl/pci: Remove duplicate host_bridge->native_aer checking Yanfei Xu (4): cxl/pci: Fix to record only non-zero ranges cxl/pci: Remove duplicated implementation of waiting for memory_info_valid cxl/pci: Check Mem_info_valid bit for each applicable DVSEC cxl/pci: simplify the check of mem_enabled in cxl_hdm_decode_init() Yuesong Li (1): cxl/port: Convert to use ERR_CAST() .../driver-api/cxl/access-coordinates.rst | 91 ++++ Documentation/driver-api/cxl/index.rst | 1 + MAINTAINERS | 3 +- drivers/acpi/apei/einj-cxl.c | 2 +- drivers/acpi/apei/ghes.c | 2 +- drivers/cxl/core/cdat.c | 508 ++++++++++++++++++++- drivers/cxl/core/core.h | 4 +- drivers/cxl/core/mbox.c | 96 ++-- drivers/cxl/core/memdev.c | 41 +- drivers/cxl/core/pci.c | 168 +++---- drivers/cxl/core/port.c | 208 +++++---- drivers/cxl/core/region.c | 81 ++-- drivers/cxl/cxl.h | 9 +- drivers/cxl/cxlmem.h | 27 +- drivers/cxl/mem.c | 29 +- drivers/cxl/pci.c | 91 ++-- drivers/cxl/pmem.c | 26 +- drivers/cxl/port.c | 2 +- drivers/cxl/security.c | 23 +- include/{linux/einj-cxl.h => cxl/einj.h} | 0 include/{linux/cxl-event.h => cxl/event.h} | 0 include/cxl/mailbox.h | 28 ++ tools/testing/cxl/Kbuild | 2 +- tools/testing/cxl/mock_acpi.c | 2 +- tools/testing/cxl/test/mem.c | 44 +- tools/testing/cxl/test/mock.c | 10 +- 26 files changed, 1092 insertions(+), 406 deletions(-) create mode 100644 Documentation/driver-api/cxl/access-coordinates.rst rename include/{linux/einj-cxl.h => cxl/einj.h} (100%) rename include/{linux/cxl-event.h => cxl/event.h} (100%) create mode 100644 include/cxl/mailbox.h .
