Commit 34452ac3 ("drm/amdgpu: don't use BACO for reset in S3 ") doesn't help, so the issue is something different. Assuming that to make HDA resume to D0 fully realized, it needs to be successfully put to D3 first. And this guesswork proves working, by moving amdgpu_asic_reset() to noirq callback, so it's called after HDA function is in D3.

"Pre-multiplied" is the default pixel blend mode for KMS/DRM, as documented in supported_modes of drm_plane_create_blend_mode_property(): https://cgit.freedesktop.org/drm/drm-misc/tree/drivers/gpu/drm/drm_blend.c In this mode, both 'pixel alpha' and 'plane alpha' participate in the calculation, as described by the pixel blend mode formula in KMS/DRM documentation: out.rgb = plane_alpha * fg.rgb + (1 - (plane_alpha * fg.alpha)) * bg.rgb Considering the blend config mechanisms we have in the driver so far, the alpha mode that better fits this blend mode is the _PER_PIXEL_ALPHA_COMBINED_GLOBAL_GAIN, where the value for global_gain is the plane alpha (global_alpha). With this change, alpha property stops to be ignored. It also addresses Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1734 v2: * keep the 8-bit value for global_alpha_value (Nicholas) * correct the logical ordering for combined global gain (Nicholas) * apply to dcn10 too (Nicholas) Signed-off-by:

When building with CONFIG_PM=y and CONFIG_PM_SLEEP=n (such as ARCH=riscv allmodconfig), the following warnings/errors occur: drivers/gpu/drm/msm/adreno/adreno_device.c:679:12: error: 'adreno_system_resume' defined but not used [-Werror=unused-function] 679 | static int adreno_system_resume(struct device *dev) | ^~~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/msm/adreno/adreno_device.c:655:12: error: 'adreno_system_suspend' defined but not used [-Werror=unused-function] 655 | static int adreno_system_suspend(struct device *dev) | ^~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors These functions are only used in SET_SYSTEM_SLEEP_PM_OPS(), which evaluates to empty when CONFIG_PM_SLEEP is not set, making these functions unused. To resolve this, use the SYSTEM_SLEEP_PM_OPS() and RUNTIME_PM_OPS() macros, which were introduced in commit 1a3c7bb0 ("PM: core: Add new *_PM_OPS macros, deprecate old ones"). They are designed to avoid these compiler warnings while still guarding their use on CONFIG_PM{,_SLEEP}=y.

The member 'msm_dsi->connector' isn't assigned until msm_dsi_manager_connector_init() returns (see msm_dsi_modeset_init() and how it assigns the return value). Therefore this pointer is going to be NULL here. Let's use 'connector' which is what was intended.

kzalloc() is a memory allocation function which can return NULL when some internal memory errors happen. So it is better to check it to prevent potential wrong memory access. Besides, since mdp5_plane_reset() is void type, so we should better set `plane-state` to NULL after releasing it. Signed-off-by:

The intent of the version check in the mmap ioctl was to maintain support for existing platforms (i.e., ADL/RPL and earlier), but drop support on all future igpu platforms. As we've seen on the dgpu side, the hardware teams are using a more fine-grained numbering system for IP version numbers these days, so it's possible the version number associated with our next igpu could be some form of "12.xx" rather than 13 or higher. Comparing against the full ver.release number will ensure the intent of the check is maintained no matter what numbering the hardware teams settle on.

They are the final bits in the removal of the default_attrs field in struct kobj_type. I had to wait until after 5.18-rc1 for all of the changes to do this came in through different development trees, and then one new user snuck in. So this series has two changes: - removal of the default_attrs field in the powerpc/pseries/vas code. The change has been acked by the PPC maintainers to come through this tree - removal of default_attrs from struct kobj_type now that all in-kernel users are removed. This cleans up the kobject code a little bit and removes some duplicated functionality that confused people (now there is only one way to do default groups) Both of these have been in linux-next for all of this week with no reported problems" * tag 'driver-core-5.18-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: kobject: kobj_type: remove default_attrs powerpc/pseries/vas: use default_groups in kobj_type

If objdump writes to stderr it can block waiting for it to be read. As perf doesn't read stderr then progress stops with perf waiting for stdout output. Signed-off-by:

The 'perf bench epoll' testcase fails on systems with more than 1K CPUs. Testcase: perf bench epoll all Result snippet: <<>> Run summary [PID 106497]: 1399 threads monitoring on 64 file-descriptors for 8 secs. perf: pthread_create: No such file or directory <<>> In epoll benchmarks (ctl, wait) pthread_create is invoked in do_threads from respective bench_epoll_* function. Though the logs shows direct failure from pthread_create, the actual failure is from "sched_setaffinity" returning EINVAL (invalid argument). This happens because the default mask size in glibc is 1024. To overcome this 1024 CPUs mask size limitation of cpu_set_t, change the mask size using the CPU_*_S macros. Patch addresses this by fixing all the epoll benchmarks to use CPU_ALLOC to allocate cpumask, CPU_ALLOC_SIZE for size, and CPU_SET_S to set the mask. Reported-by:

Since commit bb30acae ("perf report: Bail out --mem-mode if mem info is not available") "perf mem report" and "perf report --mem-mode" don't allow opening the file unless one of the events has PERF_SAMPLE_DATA_SRC set. SPE doesn't have this set even though synthetic memory data is generated after it is decoded. Fix this issue by setting DATA_SRC on SPE events. This has no effect on the data collected because the SPE driver doesn't do anything with that flag and doesn't generate samples.

Commit Fixes: b9f6fbb3 ("perf arm64: Inject missing frames when using 'perf record --call-graph=fp'") intended to add a 'best effort' DWARF unwind that improved the frame pointer stack in most scenarios. It's expected that the unwind will fail sometimes, but this shouldn't be reported as an error. It only works when the return address can be determined from the contents of the link register alone. Fix the error shown when the unwinder requires extra registers by adding a new flag that suppresses error messages. This flag is not set in the normal --call-graph=dwarf unwind mode so that behavior is not changed.
