e632bca0 - arm64: generate 64-bit syscall.tbl

Thu, 04 Jul 2024 12:33:34 +0000

arm64: generate 64-bit syscall.tblChange the asm/unistd.h header for arm64 to no longer includeasm-generic/unistd.h itself, but instead generate both the asm/unistd.hcontents and the list of entry points using the syscall.tbl scripts thatwe use on most other architectures.Once his is done for the remaining architectures, the generic unistd.hheader can be removed and the generated tbl file put in its place.The Makefile changes are more complex than they should be, I needa little help to improve those. Ideally this should be done in anarchitecture-independent way as well.Acked-by: Catalin Marinas Signed-off-by: Arnd Bergmann List of files: /linux-6.15/arch/arm64/tools/Makefile

484de085 - arm64: Factor out cpucap definitions

Mon, 16 Oct 2023 10:24:26 +0000

arm64: Factor out cpucap definitionsFor clarity it would be nice to factor cpucap manipulation out of, and the obvious place would be , butthis will clash somewhat with .Rename to ,matching what we do for , and introduce anew which includes the generated header.Subsequent patches will fill out .There should be no functional change as a result of this patch.Signed-off-by: Mark Rutland Cc: Marc Zyngier Cc: Mark Brown Cc: Suzuki K Poulose Cc: Will Deacon Signed-off-by: Catalin Marinas List of files: /linux-6.15/arch/arm64/tools/Makefile

c07d8017 - arm64/sysreg: Enable automatic generation of system register definitions

Tue, 03 May 2022 17:02:30 +0000

arm64/sysreg: Enable automatic generation of system register definitionsNow that we have a script for generating system registers hook it up to thebuild system similarly to cpucaps. Since we don't currently have any actualregister information in the input file this should produce no change in thebuilt kernel. For ease of review the register information will be convertedin separate patches.Signed-off-by: Mark Brown Acked-by: Mark Rutland Link: https://lore.kernel.org/r/20220503170233.507788-10-broonie@kernel.orgSigned-off-by: Catalin Marinas List of files: /linux-6.15/arch/arm64/tools/Makefile

819a47d2 - arm64: clean up tools Makefile

Sun, 27 Feb 2022 08:52:32 +0000

arm64: clean up tools MakefileRemove unused gen-y.Remove redundant $(shell ...) because 'mkdir' is done in cmd_gen_cpucaps.Replace $(filter-out $(PHONY), $^) with the $(real-prereqs) shorthand.The '&&' in cmd_gen_cpucaps should be replaced with ';' because it isrun under 'set -e' environment.Signed-off-by: Masahiro Yamada Link: https://lore.kernel.org/r/20220227085232.206529-1-masahiroy@kernel.orgSigned-off-by: Will Deacon List of files: /linux-6.15/arch/arm64/tools/Makefile

0c6c2d36 - arm64: Generate cpucaps.h

Wed, 28 Apr 2021 12:12:31 +0000

arm64: Generate cpucaps.hThe arm64 code allocates an internal constant to every CPU feature it candetect, distinct from the public hwcap numbers we use to expose somefeatures to userspace. Currently this is maintained manually which is anirritating source of conflicts when working on new features, to avoid thisreplace the header with a simple text file listing the names we've assignedand sort it to minimise conflicts.As part of doing this we also do the Kbuild hookup required to hook upan arch tools directory and to generate header files in there.This will result in a renumbering and reordering of the existing constants,since they are all internal only the values should not be important. Thereordering will impact the order in which some steps in enumeration handlefeatures but the algorithm is not intended to depend on this and I haven'tseen any issues when testing. Due to the UAO cpucap having been removed inthe past we end up with ARM64_NCAPS being 1 smaller than it was before.Signed-off-by: Mark Brown Reviewed-by: Mark Rutland Tested-by: Mark Rutland Link: https://lore.kernel.org/r/20210428121231.11219-1-broonie@kernel.orgSigned-off-by: Catalin Marinas List of files: /linux-6.15/arch/arm64/tools/Makefile
