Thank you!
Hi Linus, Here's the main arm64 pull request for 6.7. No major architecture features this time around, just some new HWCAP definitions, support for the Ampere SoC PMUs and a few fixes/cleanups. The bulk of the changes is reworking of the CPU capability checking code (cpus_have_cap() etc). Thanks. The following changes since commit 6465e260f48790807eef06b583b38ca9789b6072: Linux 6.6-rc3 (2023-09-24 14:31:13 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux tags/arm64-upstream for you to fetch changes up to 14dcf78a6c042dd9421b11485b394c6273568bca: Merge branch 'for-next/cpus_have_const_cap' into for-next/core (2023-10-26 17:10:18 +0100) ---------------------------------------------------------------- arm64 updates for 6.7: * Major refactoring of the CPU capability detection logic resulting in the removal of the cpus_have_const_cap() function and migrating the code to "alternative" branches where possible * Backtrace/kgdb: use IPIs and pseudo-NMI * Perf and PMU: - Add support for Ampere SoC PMUs - Multi-DTC improvements for larger CMN configurations with multiple Debug & Trace Controllers - Rework the Arm CoreSight PMU driver to allow separate registration of vendor backend modules - Fixes: add missing MODULE_DEVICE_TABLE to the amlogic perf driver; use device_get_match_data() in the xgene driver; fix NULL pointer dereference in the hisi driver caused by calling cpuhp_state_remove_instance(); use-after-free in the hisi driver * HWCAP updates: - FEAT_SVE_B16B16 (BFloat16) - FEAT_LRCPC3 (release consistency model) - FEAT_LSE128 (128-bit atomic instructions) * SVE: remove a couple of pseudo registers from the cpufeature code. There is logic in place already to detect mismatched SVE features * Miscellaneous: - Reduce the default swiotlb size (currently 64MB) if no ZONE_DMA bouncing is needed. The buffer is still required for small kmalloc() buffers - Fix module PLT counting with !RANDOMIZE_BASE - Restrict CPU_BIG_ENDIAN to LLVM IAS 15.x or newer move synchronisation code out of the set_ptes() loop - More compact cpufeature displaying enabled cores - Kselftest updates for the new CPU features ---------------------------------------------------------------- Andre Przywara (1):
