work around gcc bugs with 'asm goto' with outputs

2024-02-09T23:57:48Z

We've had issues with gcc and 'asm goto' before, and we created a 'asm_volatile_goto()' macro for that in the past: see commits 3f0116c3238a ("compiler/gcc4: Add quirk for 'asm goto' miscompilation bug") and a9f180345f53 ("compiler/gcc4: Make quirk for asm_volatile_goto() unconditional"). Then, much later, we ended up removing the workaround in commit 43c249ea0b1e ("compiler-gcc.h: remove ancient workaround for gcc PR 58670") because we no longer supported building the kernel with the affected gcc versions, but we left the macro uses around. Now, Sean Christopherson reports a new version of a very similar problem, which is fixed by re-applying that ancient workaround. But the problem in question is limited to only the 'asm goto with outputs' cases, so instead of re-introducing the old workaround as-is, let's rename and limit the workaround to just that much less common case. It looks like there are at least two separate issues that all hit in this area: (a) some versions of gcc don't mark the asm goto as 'volatile' when it has outputs: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98619 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110420 which is easy to work around by just adding the 'volatile' by hand. (b) Internal compiler errors: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110422 which are worked around by adding the extra empty 'asm' as a barrier, as in the original workaround. but the problem Sean sees may be a third thing since it involves bad code generation (not an ICE) even with the manually added 'volatile'. but the same old workaround works for this case, even if this feels a bit like voodoo programming and may only be hiding the issue.

Initialization speedups: - Lazily initialize zstd streams to save memory when not using it. - Lazily allocate/size mmap event copy. - Lazy load kernel symbols in 'perf record'. - Be lazier in allocating lost samples buffer in 'perf record'. - Don't synthesize BPF events when disabled via the command line (perf record --no-bpf-event). Assorted improvements: - Show note on AMD systems that the :p, :pp, :ppp and :P are all the same, as IBS (Instruction Based Sampling) is used and it is inherentely precise, not having levels of precision like in Intel systems. - When 'cycles' isn't available, fall back to the "task-clock" event when not system wide, not to 'cpu-clock'. - Add --debug-file option to redirect debug output, e.g.: $ perf --debug-file /tmp/perf.log record -v true - Shrink 'struct map' to under one cacheline by avoiding function pointers for selecting if addresses are identity or DSO relative, and using just a byte for some boolean struct members. - Resolve the arch specific strerrno just once to use in perf_env__arch_strerrno(). - Reduce memory for recording PERF_RECORD_LOST_SAMPLES event. Assorted fixes: - Fix the default 'perf top' usage on Intel hybrid systems, now it starts with a browser showing the number of samples for Efficiency (cpu_atom/cycles/P) and Performance (cpu_core/cycles/P). This behaviour is similar on ARM64, with its respective set of big.LITTLE processors. - Fix segfault on build_mem_topology() error path. - Fix 'perf mem' error on hybrid related to availability of mem event in a PMU. - Fix missing reference count gets (map, maps) in the db-export code. - Avoid recursively taking env->bpf_progs.lock in the 'perf_env' code. - Use the newly introduced maps__for_each_map() to add missing locking around iteration of 'struct map' entries. - Parse NOTE segments until the build id is found, don't stop on the first one, ELF files may have several such NOTE segments. - Remove 'egrep' usage, its deprecated, use 'grep -E' instead. - Warn first about missing libelf, not libbpf, that depends on libelf. - Use alternative to 'find ... -printf' as this isn't supported in busybox. - Address python 3.6 DeprecationWarning for string scapes. - Fix memory leak in uniq() in libsubcmd. - Fix man page formatting for 'perf lock' - Fix some spelling mistakes. perf tests: - Fail shell tests that needs some symbol in perf itself if it is stripped. These tests check if a symbol is resolved, if some hot function is indeed detected by profiling, etc. - The 'perf test sigtrap' test is currently failing on PREEMPT_RT, skip it if sleeping spinlocks are detected (using BTF) and point to the mailing list discussion about it. This test is also being skipped on several architectures (powerpc, s390x, arm and aarch64) due to other pending issues with intruction breakpoints. - Adjust test case perf record offcpu profiling tests for s390. - Fix 'Setup struct perf_event_attr' fails on s390 on z/VM guest, addressing issues caused by the fallback from cycles to task-clock done in this release. - Fix mask for VG register in the user-regs test. - Use shellcheck on 'perf test' shell scripts automatically to make sure changes don't introduce things it flags as problematic. - Add option to change objdump binary and allow it to be set via 'perf config'. - Add basic 'perf script', 'perf list --json" and 'perf diff' tests. - Basic branch counter support. - Make DSO tests a suite rather than individual. - Remove atomics from test_loop to avoid test failures. - Fix call chain match on powerpc for the record+probe_libc_inet_pton test. - Improve Intel hybrid tests. Vendor event files (JSON): powerpc: - Update datasource event name to fix duplicate events on IBM's Power10. - Add PVN for HX-C2000 CPU with Power8 Architecture. Intel: - Alderlake/rocketlake metric fixes. - Update emeraldrapids events to v1.02. - Update icelakex events to v1.23. - Update sapphirerapids events to v1.17. - Add skx, clx, icx and spr upi bandwidth metric.

Pull sound updates from Takashi Iwai: "It was a calm development cycle. There were an ALSA core extension for subformat PCM bits and a few ASoC core changes to support N:M mappings, while the most of remaining changes are driver-specific. Core: - API extensions for properly limiting PCM format bits via subformat - Enhanced support for N:M CPU:CODEC mappings in the core and in audio-graph-card2 ASoC: - Lots of SOF updates: fallback support to older IPC versions, notification on control changes with IPC4. Also supports for ACPI parse for the ES83xx driver that reduces quirks. - Device tree support for describing parts of the card which can be active over suspend (for very low power playback or wake word use cases) - Support for more AMD and Intel systems, NXP i.MX8m MICFIL, Qualcomm SM8250, SM8550, SM8650 and X1E80100 - Drop of Freescale MPC8610 code that is no longer supported HD-audio: - More CS35L41 codec extensions for Dell, HP and Lenovo models - TAS2781 codec extensions for Lenovo and co - New PCM subformat supports Others: - More enhancement for Scarlett2 USB mixer support - Various kselftest fixes" * tag 'sound-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (337 commits) kselftest/alsa - conf: Stringify the printed errno in sysfs_get() kselftest/alsa - mixer-test: Fix the print format specifier warning kselftest/alsa - mixer-test: Fix the print format specifier warning kselftest/alsa - mixer-test: fix the number of parameters to ksft_exit_fail_msg() ALSA: hda/tas2781: annotate calibration data endianness ALSA: hda/realtek: Fix mute and mic-mute LEDs for HP Envy X360 13-ay0xxx ALSA: hda/conexant: Fix headset auto detect fail in cx8070 and SN6140 ALSA: ac97: fix build regression ALSA: hda: cs35l41: Support more HP models without _DSD ALSA: hda/tas2781: add fixup for Lenovo 14ARB7 ALSA: hda/tas2781: add TAS2563 support for 14ARB7 ALSA: hda/tas2781: add configurable global i2c address ALSA: hda/tas2781: add ptrs to calibration functions ALSA: hda: Add driver properties for cs35l41 for Lenovo Legion Slim 7 Gen 8 serie ALSA: hda/realtek: enable SND_PCI_QUIRK for Lenovo Legion Slim 7 Gen 8 (2023) serie ALSA: hda/tas2781: configure the amp after firmware load ALSA: mark all struct bus_type as const ASoC: pxa: sspa: Don't select SND_ARM ASoC: rt5663: cancel the work when system suspends ALSA: scarlett2: Add PCM Input Switch for Solo Gen 4 ...
