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.

2025-03-03T22:51:51Z

The ICH_HCR_EL2-related macros are missing a number of control 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, unfortunately.

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.

tools: arm64: Update sysreg.h header files

2025-01-12T12:50:11Z

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.

tools: arm64: Import sysreg.h

2021-10-17T10:15:51Z

Bring-in the kernel's arch/arm64/include/asm/sysreg.h into tools/ for arm64 to make use of all the standard register definitions in consistence with the kernel. Make use of the register read/write definitions from sysreg.h, instead of the existing definitions. A syntax correction is needed for the files that use write_sysreg() to make it compliant with the new (kernel's) syntax.
