Subject: [PATCH V6 0/3] arm64/sysreg: Clean up TCR_EL1 field macros
Date: Mon, 13 Oct 2025 10:59:42 +0530 [thread overview]
Message-ID: <20251013052945.2197190-1-anshuman.khandual@arm.com> (raw)
Currently TCR_EL1 field macros are sprinkled across the arm64 platform code
including KVM implementation. Clean these up via updating required register
filed definitions in tools sysreg format and then subsequently doing all
necessary replacements. All required TCR_XXX macros have been moved from
(asm/pgtable-hwdef.h) into KVM header (asm/kvm_arm.h) for their continued
usage in KVM.
The cleanup does not cause any functional change.
This applies on v6.18-rc1

Changes in V6:
- Added back definition for TCR_SH1_MASK as KVM on arm64 uses it now
Changes in V5:
https://lore.kernel.org/all/20250921005300.2535994-1-anshuman.khandual@arm.com/
- Split tools header and KVM changes into separate patches per Will
Changes in V4:
https://lore.kernel.org/all/20250907123000.414181-1-anshuman.khandual@arm.com/
- Dropped all unused TCR_XXX macros while moving into KVM header
Changes in V3:
https://lore.kernel.org/all/20250901072037.743380-1-anshuman.khandual@arm.com/
- KVM TCR_XXX flags are expressed via TCR_EL1_XXX flags per Marc
Changes in V2:
https://lore.kernel.org/all/20250829060215.1086792-1-anshuman.khandual@arm.com/
- Fixed ARM ARM version from 7.B to L.B
- Changed UnsignedEnum into Enum per Mark
- Dropped all TCR_EL1 replacements from KVM code
- Moved existing TCR_XXX macros from (asm/pgtable-hwdef.h) into KVM header
(asm/kvm_arm.h) for their continued usage
- Dropped patches 3 and 4 which could be done subsequently
