tools headers: Update the linux/unaligned.h copy with the kernel sources

2024-10-28T15:34:28+00:00

To pick up the changes in: 7f053812dab3946c ("random: vDSO: minimize and simplify header includes") That required adding a copy of include/vdso/unaligned.h and its checking in tools/perf/check-headers.h. Addressing this perf tools build warning: Warning: Kernel ABI header differences: diff -u tools/include/linux/unaligned.h include/linux/unaligned.h Please see tools/include/uapi/README for further details.

move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23+00:00

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

perf tools: Cope with differences for lib/list_sort.c copy from the kernel

2024-10-02T18:07:32+00:00

With 6d74e1e371d43a7b ("tools/lib/list_sort: remove redundant code for cond_resched handling") we need to use the newly added hunk based exceptions when comparing the copy we carry in tools/lib/ to the original file, do it by adding the hunks that we know will be the expected diff. If at some point the original file is updated in other parts, then we should flag and check the file for update.

tools check_headers.sh: Add check variant that excludes some hunks

2024-10-02T17:50:44+00:00

With 6d74e1e371d43a7b ("tools/lib/list_sort: remove redundant code for cond_resched handling") we end up with a multi-line variation in the merge_final() implementation, one that the simple line based exceptions we had so far can't cope. Thus this check has been failing: Warning: Kernel ABI header differences: diff -u tools/lib/list_sort.c lib/list_sort.c So add a new check routine that uses grep -vf to exclude some hunks that we store in the tools/perf/check-header_ignore_hunks/ directory. This first patch is just the new check routine, the next one will use it to check lib/list_sort.c.

perf tools: Build x86 32-bit syscall table from arch/x86/entry/syscalls/syscall_32.tbl

2024-09-02T14:13:40+00:00

To remove one more use of the audit libs and address a problem reported with a recent change where a function isn't available when using the audit libs method, that should really go away, this being one step in that direction. The script used to generate the 64-bit syscall table was already parametrized to generate for both 64-bit and 32-bit, so just use it and wire the generated table to the syscalltbl.c routines.

Revert "tools headers: Remove almost unused copy of uapi/stat.h, add few conditional defines"

2024-04-19T01:22:52+00:00

This reverts commit a672af9139a843eb7a48fd7846bb6df8f81b5f86. By now it is not used for building tools/perf, but Stephen Rothwell reported that when building on a O= directory that had been built with torvalds/master and this perf build command line: $ make -C tools/perf -f Makefile.perf -s -O -j60 O=/home/sfr/next/perf NO_BPF_SKEL=1 If we then merge perf-tools-next, as he did for linux-next, then we end up with a build failure for libbpf: PERF_VERSION = 6.9.rc3.g42c4635c8dee make[3]: *** No rule to make target '/home/sfr/next/next/tools/include/uapi/linux/stat.h', needed by '/home/sfr/next/perf/libbpf/staticobjs/libbpf.o'.

perf beauty: Move uapi/linux/vhost.h copy out of the directory used to build perf

2024-03-21T23:44:35+00:00

It is only used to generate string tables, not to build perf, so move it to the tools/perf/trace/beauty/include/ hierarchy, that is used just for scraping. This is a something that should've have happened, as happened with the linux/socket.h scrapper, do it now as Ian suggested while doing an audit/refactor session in the headers used by perf. No other tools/ living code uses it, just coming from either 'make install_headers' or from the system /usr/include/ directory.

perf beauty: Introduce scrape script for the 'statx' syscall 'mask' argument

2024-03-21T16:54:40+00:00

It was using the first variation on producing a string representation for a binary flag, one that used the system's stat.h and preprocessor tricks that had to be updated everytime a new flag was introduced. Use the more recent scrape script + strarray + strarray__scnprintf_flags() combo. $ tools/perf/trace/beauty/statx_mask.sh static const char *statx_mask[] = { [ilog2(0x00000001) + 1] = "TYPE", [ilog2(0x00000002) + 1] = "MODE", [ilog2(0x00000004) + 1] = "NLINK", [ilog2(0x00000008) + 1] = "UID", [ilog2(0x00000010) + 1] = "GID", [ilog2(0x00000020) + 1] = "ATIME", [ilog2(0x00000040) + 1] = "MTIME", [ilog2(0x00000080) + 1] = "CTIME", [ilog2(0x00000100) + 1] = "INO", [ilog2(0x00000200) + 1] = "SIZE", [ilog2(0x00000400) + 1] = "BLOCKS", [ilog2(0x00000800) + 1] = "BTIME", [ilog2(0x00001000) + 1] = "MNT_ID", [ilog2(0x00002000) + 1] = "DIOALIGN", [ilog2(0x00004000) + 1] = "MNT_ID_UNIQUE", }; $ Now we need a copy of uapi/linux/stat.h from tools/include/ in the scrape only directory tools/perf/trace/beauty/include.
