There are several steps required to put the system into system suspend. Some of these steps may fail, so the driver should pass up the errors if they occur. Signed-off-by:

In order to properly system suspend, it is necessary to unload the firmware and ensure the chip is ready for shutdown (if necessary). If the system is currently in runtime suspend, it is necessary to wake up the device, and then make it ready. Currently, the wake does not correctly resync the device, which may mean it cannot suspend correctly. Fix this by performaing a resync. Signed-off-by:

Currently, we do not check the return status of the pause command, immediately after we load firmware. If the pause has failed, the firmware is not running. Signed-off-by:

To ensure the chip has correctly powered up or down before continuing, the driver will now poll a register, rather than wait a fixed delay. Acked-by:

To enable the speaker output in external boost mode, 2 registers must be set, one after another. The longer the time between the writes of the two registers, the more likely, and more loudly a pop may occur. To minimize this, an mbox command can be used to allow the firmware to perform this action, minimizing any delay between write, thus minimizing any pop or click as a result. The old method will remain when running without firmware. Acked-by:

Instead of open-code, use the new standard helper to manage vmaster stuff for code simplification. Also, handle the errors from the helper more properly instead of silently ignoring. The code changes the call order of snd_ctl_add() of the vmaster object and its followers for avoiding the possible memory leaks at error path. But there should be no difference in the functionality.

ALSA: Make control API taking controls_rwsem consistently A few ALSA control API helpers like snd_ctl_rename(), snd_ctl_remove() and snd_ctl_find_*() suppose the callers taking card->controls_rwsem. But it's error-prone and fragile. This patch set tries to change those API functions to take the card->controls>rwsem internally by themselves, so that the drivers don't need to take care of lockings. After applying this patch set, only a couple of places still touch card->controls_rwsem (which are OK-ish as they need for traversing the control linked list).

For reducing the unnecessary use of controls_rwsem in the drivers, this patch adds a new variant for snd_ctl_find_*() helpers: snd_ctl_find_id_locked() and snd_ctl_find_numid_locked() look for a kctl element inside the card->controls_rwsem -- that is, doing the very same as what snd_ctl_find_id() and snd_ctl_find_numid() did until now. snd_ctl_find_id() and snd_ctl_find_numid() remain same, i.e. still unlocked version, but they will be switched to locked version once after all callers are replaced. The patch also replaces the calls of snd_ctl_find_id() and snd_ctl_find_numid() in a few places; all of those are places where we know that the functions are called properly with controls_rwsem held. All others are without rwsem (although they should have been). After this patch, we'll turn on the locking in snd_ctl_find_id() and snd_ctl_find_numid() to be more race-free.

The controls_rwsem of snd_card object is rather an internal lock, and not really meant to be used by others for its data protection. This patch addresses it by replacing the controls_rwsem usages with the own (new) mutex. Note that the up_write() and down_write() calls around gbaudio_remove_component_controls() are simply dropped without replacement. These temporary up/down were a workaround since gbaudio_remove_component_controls() itself took the rwsem. Now it was also gone, we can clean up the workaround, too. Acked-by:

So far, snd_ctl_remove() requires its caller to take card->controls_rwsem manually before the call for avoiding possible races. However, many callers don't care and miss the locking. Basically it's cumbersome and error-prone to enforce it to each caller. Moreover, card->controls_rwsem is a field that should be used only by internal or proper helpers, and it's not to be touched at random external places. This patch is an attempt to make those calls more consistent: now snd_ctl_remove() takes the card->controls_rwsem internally, just like other API functions for kctls. Since a few callers already take the controls_rwsem locks, the patch removes those locks at the same time, too. Link: https://lore.kernel.org/r/20230718141304.1032-5-tiwai@suse.deSigned-off-by:

Takashi Iwai authored
snd_ctl_rename() expects that card->controls_rwsem is held in the caller side for avoiding possible races, but actually no one really did that. It's likely because this operation is done usually only at the device initialization where no race can happen. But, it's still safer to take a lock, so we just take the lock inside snd_ctl_rename() like most of other API functions do.

Pull cleanup of HD-audio PCI IDs. Signed-off-by: -
Amadeusz Sławiński authored
Use PCI device IDs from pci_ids.h header. BSW replaces CHV, as 0x22a8 was added in PCI header as BSW ID for consistency, as they are same (similar) platforms. The ACPI IDs are used only internally and lower 16 bits uniquely define the device as vendor ID for Intel is 8086 for all of them. Use PCI_DEVICE_DATA() to match PCI device to be consistent with other Intel audio drivers. Suggested-by:
