Nothing particularly remarkable here given that both pKVM and NV are in a half-baked state upstream, although the selftests fix does plug a new test failure as of 6.13.

The bulk of the changes are around debug and protect mode, both of which are being radically cleaned up. On the feature side, we gain support for non-protected guests in protected mode, EL2 timer support, and some better CoreSight support. The rest is the usual mix of cleanups and bug fixes. Note that this drags two other branches: - arm64's for-next/cpufeature to resolve conflicts that were not trivial to resolve - kvmarm-fixes-6.13-3 which was only merged in 6.13-rc7, while this branch is firmly based on -rc3, and we had some dependencies with it. As usual, gory details in the tag below. Please pull, M. The following changes since commit 78d4f34e2115b517bcbfe7ec0d018bbbb6f9b0b8: Linux 6.13-rc3 (2024-12-15 15:58:23 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm.git tags/kvmarm-6.14 for you to fetch changes up to 01009b06a6b52d8439c55b530633a971c13b6cb2: arm64/sysreg: Get rid of TRFCR_ELx SysregFields (2025-01-17 11:07:55 +0000) ---------------------------------------------------------------- KVM/arm64 updates for 6.14 * New features: - Support for non-protected guest in protected mode, achieving near feature parity with the non-protected mode - Support for the EL2 timers as part of the ongoing NV support - Allow control of hardware tracing for nVHE/hVHE * Improvements, fixes and cleanups: - Massive cleanup of the debug infrastructure, making it a bit less awkward and definitely easier to maintain. This should pave the way for further optimisations - Complete rewrite of pKVM's fixed-feature infrastructure, aligning it with the rest of KVM and making the code easier to follow - Large simplification of pKVM's memory protection infrastructure - Better handling of RES0/RES1 fields for memory-backed system registers - Add a workaround for Qualcomm's Snapdragon X CPUs, which suffer from a pretty nasty timer bug - Small collection of cleanups and low-impact fixes * Dependencies - Merge arm64/for-next/cpufeature to resolve conflicts - Merge kvmarm-fixes-6.13-3 on which the non-protected memory management depends ---------------------------------------------------------------- Fuad Tabba (16): KVM: arm64: Group setting traps for protected VMs by control register KVM:
