2023-12-30ALSA: mark all struct bus_type as constGreg Kroah-Hartman
Now that the driver core can properly handle constant struct bus_type, move all of the sound subsystem struct bus_type structures as const, placing them into read-only memory which can not be modified at runtime. Note, this fixes a duplicate definition of ac97_bus_type, which somehow was declared extern in a .h file, and then static as a prototype in a .c file, and then properly later on in the same .c file. Amazing that no compiler warning ever showed up for this.

2023-11-27ALSA: hda: Upgrade stream-format infrastructureCezary Rojewski
Introduce a set of functions that ultimately facilite SDxFMT-related calculations in atomic manner: First, introduce snd_pcm_subformat_width() and snd_pcm_hw_params_bits() helpers that separate the base functionality from the HDAudio-specific one. snd_hdac_format_normalize() - format converter. S20_LE, S24_LE and their unsigned and BE friends are invalid from HDAudio perspective but still can be specified as function argument due to compatibility reasons. snd_hdac_stream_format_bits() - obtain just the bits-per-sample value. Does not ignore subformat and msbits parameters. snd_hdac_stream_format() and snd_hdac_spdif_stream_format() - obtain the SDxFMT value given the audio format parameters. The former is stripped away of spdif-related information. Useful for users that do not care about them.

2023-11-21ALSA: hda: Refer to correct stream index at loopsTakashi Iwai
In a couple of loops over the all streams, we check the bitmap against the loop counter. A more correct reference would be, however, the index of each stream, instead. This patch corrects the check of bitmaps to the stream index. Note that this change doesn't fix anything for now; all existing drivers set up the stream indices properly, hence the loop count is always equal with the stream index. That said, this change is only for consistency. Link: https://lore.kernel.org/r/20231121154125.4888-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>

Xe is a new GPU driver that re-uses the display (and sound) code from i915. It's no longer possible to load i915, as the GPU can be driven by the xe driver instead.

2023-10-19ALSA: hda: i915: Allow override of gpu binding.Maarten Lankhorst
Selecting CONFIG_DRM selects CONFIG_VIDEO_NOMODESET, which exports video_firmware_drivers_only(). This can be used as a first approximation on whether i915 will be available. It's safe to use as this is only built when CONFIG_SND_HDA_I915 is selected by CONFIG_I915. It's not completely fool proof, as you can boot with "nomodeset i915.modeset=1" to make i915 load regardless, or use "i915.force_probe=!*" to never load i915, but the common case of booting with nomodeset to disable all GPU drivers this will work as intended. Because of this, we add an extra module parameter, snd_hda_core.gpu_bind that can be used to signal users intent. -1 follows nomodeset, 0 disables binding, 1 forces wait/-EPROBE_DEFER on binding.

2023-05-22ALSA: hda: Fix unhandled register update during auto-suspend periodTakashi Iwai
It's reported that the recording started right after the driver probe doesn't work properly, and it turned out that this is related with the codec auto-suspend. Namely, after the probe phase, the usage count goes zero, and the auto-suspend is programmed, but the codec is kept still active until the auto-suspend expiration. When an application (e.g. alsactl) updates the mixer values at this moment, the values are cached but not actually written. Then, starting arecord thereafter also results in the silence because of the missing unmute. The root cause is the handling of "lazy update" mode; when a mixer value is updated *after* the suspend, it should update only the cache and exits. At the resume, the cached value is written to the device, in turn. The problem is that the current code misinterprets the state of auto-suspend as if it were already suspended. Although we can add the check of the actual device state after pm_runtime_get_if_in_use() for catching the missing state, this won't suffice; the second call of regmap_update_bits_check() will skip writing the register because the cache has been already updated by the first call. So we'd need fixes in two different places. OTOH, a simpler fix is to replace pm_runtime_get_if_in_use() with pm_runtime_get_if_active() (with ign_usage_count=true). This change implies that the driver takes the pm refcount if the device is still in ACTIVE state and continues the processing. A small caveat is that this will leave the auto-suspend timer. But, since the timer callback itself checks the device state and aborts gracefully when it's active, this won't be any substantial problem. Long story short: we address the missing register-write problem just by replacing the pm_runtime_*() call in snd_hda_keep_power_up().

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core updates from Greg KH: "Here is the large set of driver core changes for 6.3-rc1. There's a lot of changes this development cycle, most of the work falls into two different categories: - fw_devlink fixes and updates. This has gone through numerous review cycles and lots of review and testing by lots of different devices. Hopefully all should be good now, and Saravana will be keeping a watch for any potential regression on odd embedded systems. - driver core changes to work to make struct bus_type able to be moved into read-only memory (i.e. const) The recent work with Rust has pointed out a number of areas in the driver core where we are passing around and working with structures that really do not have to be dynamic at all, and they should be able to be read-only making things safer overall. This is the contuation of that work (started last release with kobject changes) in moving struct bus_type to be constant. We didn't quite make it for this release, but the remaining patches will be finished up for the release after this one, but the groundwork has been laid for this effort. Other than that we have in here: - debugfs memory leak fixes in some subsystems - error path cleanups and fixes for some never-able-to-be-hit codepaths. - cacheinfo rework and fixes - Other tiny fixes, full details are in the shortlog All of these have been in linux-next for a while with no reported problems" [ Geert Uytterhoeven points out that that last sentence isn't true, and that there's a pending report that has a fix that is queued up - Linus ] * tag 'driver-core-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (124 commits) debugfs: drop inline constant formatting for ERR_PTR(-ERROR) OPP: fix error checking in opp_migrate_dentry() debugfs: update comment of debugfs_rename() i3c: fix device.h kernel-doc warnings dma-mapping: no need to pass a bus_type into get_arch_dma_ops() driver core: class: move EXPORT_SYMBOL_GPL() lines to the correct place Revert "driver core: add error handling for devtmpfs_create_node()" Revert "devtmpfs: add debug info to handle()" Revert "devtmpfs: remove return value of devtmpfs_delete_node()" driver core: cpu: don't hand-override the uevent bus_type callback. devtmpfs: remove return value of devtmpfs_delete_node() devtmpfs: add debug info to handle() driver core: add error handling for devtmpfs_create_node() driver core: bus: update my copyright notice driver core: bus: add bus_get_dev_root() function driver core: bus: constify bus_unregister() driver core: bus: constify some internal functions driver core: bus: constify bus_get_kset() driver core: bus: constify bus_register/unregister_notifier() driver core: remove private pointer from struct bus_type ...
