KVM: arm64: selftests: Remove ARM64_FEATURE_FIELD_BITS and its last user

2025-11-27T18:16:46Z

ARM64_FEATURE_FIELD_BITS is set to 4 but not all ID register fields are 4 bits. See for instance ID_AA64SMFR0_EL1. The last user of this define, ARM64_FEATURE_FIELD_BITS, is the set_id_regs selftest. Its logic assumes the fields aren't a single bits; assert that's the case and stop using the define. As there are no more users, ARM64_FEATURE_FIELD_BITS is removed from the arm64 tools sysreg.h header. A separate commit removes this from the kernel version of the header.

arm64: Replace ASSEMBLY with ASSEMBLER in non-uapi headers

2025-11-11T19:35:59Z

While the GCC and Clang compilers already define __ASSEMBLER__ automatically when compiling assembly code, __ASSEMBLY__ is a macro that only gets defined by the Makefiles in the kernel. This can be very confusing when switching between userspace and kernelspace coding, or when dealing with uapi headers that rather should use __ASSEMBLER__ instead. So let's standardize now on the __ASSEMBLER__ macro that is provided by the compilers. This is a mostly mechanical patch (done with a simple "sed -i" statement), except for the following files where comments with mis-spelled macros were tweaked manually: arch/arm64/include/asm/stacktrace/frame.h arch/arm64/include/asm/kvm_ptrauth.h arch/arm64/include/asm/debug-monitors.h arch/arm64/include/asm/esr.h arch/arm64/include/asm/scs.h arch/arm64/include/asm/memory.h Signed-off-by: Thomas Huth Signed-off-by: Catalin Marinas

KVM: arm64: Get rid of ARM64_FEATURE_MASK()

2025-08-21T23:31:56Z

The ARM64_FEATURE_MASK() macro was a hack introduce whilst the automatic generation of sysreg encoding was introduced, and was too unreliable to be entirely trusted. We are in a better place now, and we could really do without this macro. Get rid of it altogether.

arm64: sysreg: Add layout for ICH_MISR_EL2

2025-03-03T22:51:51Z

The ICH_MISR_EL2-related macros are missing a number of status bits that we are about to handle. Take this opportunity to fully describe the layout of that register as part of the automatic generation infrastructure.

arm64: sysreg: Add layout for ICH_VTR_EL2

2025-03-03T22:51:51Z

The ICH_VTR_EL2-related macros are missing a number of config bits that we are about to handle. Take this opportunity to fully describe the layout of that register as part of the automatic generation infrastructure. This results in a bit of churn to repaint constants that are now generated with a different format.

arm64/sysreg/tools: Move TRFCR definitions to sysreg

2025-01-12T12:50:11Z

Convert TRFCR to automatic generation. Add separate definitions for ELx and EL2 as TRFCR_EL1 doesn't have CX. This also mirrors the previous definition so no code change is required. Also add TRFCR_EL12 which will start to be used in a later commit. Unfortunately, to avoid breaking the Perf build with duplicate definition errors, the tools copy of the sysreg.h header needs to be updated at the same time rather than the usual second commit. This is because the generated version of sysreg (arch/arm64/include/generated/asm/sysreg-defs.h), is currently shared and tools/ does not have its own copy.

Created with the following: cp include/linux/kasan-tags.h tools/include/linux/ cp arch/arm64/include/asm/sysreg.h tools/arch/arm64/include/asm/ Update the tools copy of sysreg.h so that the next commit to add a new register doesn't have unrelated changes in it. Because the new version of sysreg.h includes kasan-tags.h, that file also now needs to be copied into tools.
