2024-03-21perf beauty: Move uapi/sound/asound.h copy out of the directory used to ↵Arnaldo Carvalho de Melo1-1252/+0
build perf It is used only 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.

2023-11-27ALSA: pcm: Introduce MSBITS subformat interfaceJaroslav Kysela1-2/+5
Improve granularity of format selection for S32/U32 formats by adding constants representing 20, 24 and MAX most significant bits. The MAX means the maximum number of significant bits which can the physical format hold. For 32-bit formats, MAX is related to 32 bits. For 8-bit formats, MAX is related to 8 bits etc. As there is only one user currently (format S32_LE), subformat is represented by a simple u32 and stores flags only for that one user alone. The approach of subformat being part of struct snd_pcm_hardware is a compromise between ALSA and ASoC allowing for hw_params-intersection code to be alloc/free-less while not adding any new responsibilities to ASoC runtime structures.

2022-06-28treewide: uapi: Replace zero-length arrays with flexible-array membersGustavo A. R. Silva1-1/+1
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. This code was transformed with the help of Coccinelle: (linux-5.19-rc2$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch) @@ identifier S, member, array; type T1, T2; @@ struct S { ... T1 member; T2 array[ - 0 ]; }; -fstrict-flex-arrays=3 is coming and we need to land these changes to prevent issues like these in the short future: ../fs/minix/dir.c:337:3: warning: 'strcpy' will always overflow; destination buffer has size 0, but the source string has length 2 (including NUL byte) [-Wfortify-source] strcpy(de3->name, "."); ^ Since these are all [0] to [] changes, the risk to UAPI is nearly zero. If this breaks anything, we can use a union with a new member name.

2017-11-04tools/headers: Synchronize kernel ABI headersIngo Molnar1-0/+1
After the SPDX license tags were added a number of tooling headers got out of sync with their kernel variants, generating lots of build warnings. Sync them: - tools/arch/x86/include/asm/disabled-features.h, tools/arch/x86/include/asm/required-features.h, tools/include/linux/hash.h: Remove the SPDX tag where the kernel version does not have it. - tools/include/asm-generic/bitops/__fls.h, tools/include/asm-generic/bitops/arch_hweight.h, tools/include/asm-generic/bitops/const_hweight.h, tools/include/asm-generic/bitops/fls.h, tools/include/asm-generic/bitops/fls64.h, tools/include/uapi/asm-generic/ioctls.h, tools/include/uapi/asm-generic/mman-common.h, tools/include/uapi/sound/asound.h, tools/include/uapi/linux/kvm.h, tools/include/uapi/linux/perf_event.h, tools/include/uapi/linux/sched.h, tools/include/uapi/linux/vhost.h, tools/include/uapi/sound/asound.h: Add the SPDX tag of the respective kernel header. - tools/include/uapi/linux/bpf_common.h, tools/include/uapi/linux/fcntl.h, tools/include/uapi/linux/hw_breakpoint.h, tools/include/uapi/linux/mman.h, tools/include/uapi/linux/stat.h, Change the tag to the kernel header version: -/* SPDX-License-Identifier: GPL-2.0 */ +/* SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note */ Also sync other header details: - include/uapi/sound/asound.h: Fix pointless end of line whitespace noise the header grew in this cycle. - tools/arch/x86/lib/memcpy_64.S: Sync the code and add tools/include/asm/export.h with dummy wrappers to support building the kernel side code in a tooling header environment. - tools/include/uapi/asm-generic/mman.h, tools/include/uapi/linux/bpf.h: Sync other details that don't impact tooling's use of the ABIs.

We will use it to generate tables for beautifying ioctl's 'cmd' arg.
