Subject: [GIT PULL] arm64 updates 6.15-rc1
Hi Linus,
Please pull the arm64 updates for 6.15-rc1 below. Nothing major this
time around. Apart from the usual perf/PMU updates, some page table
cleanups, the notable features are average CPU frequency based on the
AMUv1 counters, CONFIG_HOTPLUG_SMT and MOPS instructions (memcpy/memset)
in the uaccess routines.
Thanks.
The following changes since commit 0ad2507d5d93f39619fc42372c347d6006b64319:
Linux 6.14-rc3 (2025-02-16 14:02:44 -0800)
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 64fa6b9322a904198589c0479dca6f2ed7f2eb04:
Merge branch 'for-next/el2-enable-feat-pmuv3p9' into for-next/core (2025-03-25 19:32:32 +0000)
----------------------------------------------------------------
arm64 updates for 6.15:
Perf and PMUs:
- Support for the "Rainier" CPU PMU from Arm
- Preparatory driver changes and cleanups that pave the way for BRBE
support
- Support for partial virtualisation of the Apple-M1 PMU
- Support for the second event filter in Arm CSPMU designs
- Minor fixes and cleanups (CMN and DWC PMUs)
- Enable EL2 requirements for FEAT_PMUv3p9
Power, CPU topology:
- Support for AMUv1-based average CPU frequency
- Run-time SMT control wired up for arm64 (CONFIG_HOTPLUG_SMT). It adds
a generic topology_is_primary_thread() function overridden by x86 and
powerpc
New(ish) features:
- MOPS (memcpy/memset) support for the uaccess routines
Security/confidential compute:
- Fix the DMA address for devices used in Realms with Arm CCA. The
CCA architecture uses the address bit to differentiate between shared
and private addresses
- Spectre-BHB: assume CPUs Linux doesn't know about vulnerable by
default
Memory management clean-ups:
- Drop the P*D_TABLE_BIT definition in preparation for 128-bit PTEs
- Some minor page table accessor clean-ups
- PIE/POE (permission indirection/overlay) helpers clean-up
Kselftests:
- MTE: skip hugetlb tests if MTE is not supported on such mappings and
user correct naming for sync/async tag checking modes
Miscellaneous:
- Add a PKEY_UNRESTRICTED definition as 0 to uapi (toolchain people
request)
- Sysreg updates for new register fields
- CPU type info for some Qualcomm Kryo cores
