When the codec complete the command, it sends interrupt and writes response entries to memory, howerver, the write requests sometimes are not actually synchronized to memory when driver handle hdac interrupt on Glenfly Gpus. If the RIRB status is not updated in the interrupt handler, azx_rirb_get_response keeps trying to recevie a response from rirb until 1s timeout.

Commit 586bc4aab878 ("ALSA: hda/hdmi - fix vgaswitcheroo detection for AMD") caused only AMD gpu's with PX to have their audio component register with vga_switcheroo. This meant that Apple Macbooks with apple-gmux as the gpu switcher no longer had the audio client registering, so when the gpu is powered off by vga_switcheroo snd_hda_intel is unaware that it should have suspended the device: amdgpu: switched off snd_hda_intel 0000:03:00.1: Unable to change power state from D3hot to D0, device inaccessible snd_hda_intel 0000:03:00.1: CORB reset timeout#2, CORBRP = 65535 To resolve this, we use apple_gmux_detect() and register a vga_switcheroo audio client when apple-gmux is detected.

2023-02-03ALSA: hda: Fix the control element identification for multiple codecsJaroslav Kysela
Some motherboards have multiple HDA codecs connected to the serial bus. The current code may create multiple mixer controls with the almost identical identification. The current code use id.device field from the control element structure to store the codec address to avoid such clashes for multiple codecs. Unfortunately, the user space do not handle this correctly. For mixer controls, only name and index are used for the identifiers. This patch fixes this problem to compose the index using the codec address as an offset in case, when the control already exists. It is really unlikely that one codec will create 10 similar controls. This patch adds new kernel module parameter 'ctl_dev_id' to allow select the old behaviour, too. The CONFIG_SND_HDA_CTL_DEV_ID Kconfig option sets the default value.

2022-11-01ALSA: hda: clarify comments on SCF changesPierre-Louis Bossart
The commit 1f9d3d98694b1 ("ALSA: hda - set intel audio clock to a proper value") added a number of misleading comments. There is no ability to detect if an SCF value was set or not, what the code does is prevent the use of the 6MHz audio clock represented by the value 0 in LCTL.SCF. Changing the SCF settings does require the link to be power-cycled, but in all other cases the link is powered automatically when exiting reset. In other words, the power-cycle is an exception to the rule that the HDaudio legacy driver does not need to program SPA/CPA bits. In addition, the SCF related changes are only relevant for the first link. No functionality change, only comment clarifications.

2022-09-06ALSA: hda: Once again fix regression of page allocations with IOMMUTakashi Iwai
The last fix for trying to recover the regression on AMD platforms, unfortunately, leaded to yet another regression: it turned out that IOMMUs don't like the usage of raw page allocations. This is yet another attempt for addressing the log saga; at this time, we re-use the existing buffer allocation mechanism with SG-pages although we require only single pages. The SG buffer allocation itself was confirmed to work for stream buffers, so it's relatively easy to adapt for other places. The only problem is: although the HD-audio code is accessing the address directly via dmab->address field, SG-pages don't set up it. For the ease of adaption, we now set up the dmab->addr field from the address of the first page as default, so that it can run with the HD-audio driver code as-is without the excessive call of snd_sgbuf_get_addr() multiple times; that's the only change in the memalloc helper side. The rest is nothing but a flip of the dma_type field in the HD-audio side.

2022-02-09ALSA: hda: Fix driver index handling at re-bindingTakashi Iwai
HD-audio driver handles the multiple instances and keeps the static index that is incremented at each probe. This becomes a problem when user tries to re-bind the device via sysfs multiple times; as the device index isn't cleared unlike rmmod case, it points to the next element at re-binding, and eventually later you can't probe any more when it reaches to SNDRV_CARDS_MAX (usually 32). This patch is an attempt to improve the handling at rebinding. Instead of a static device index, now we keep a bitmap and assigns to the first zero bit position. At the driver remove, in return, the bitmap slot is cleared again, so that it'll be available for the next probe.

2021-11-20ALSA: hda: Remove redundant runtime PM callsTakashi Iwai
The previous fix for more comprehensive runtime PM calls turned out to be not good as hoped; a few calls including pm_runtime_enable() and pm_runtime_disable() are rather utterly superfluous for PCI devices, even triggering a kernel error message. Better to drop those calls. Note that the problem we wanted to solve with that commit seems irrelevant with the fix itself; the original bug (a GPF at azx_remove()) was likely a regression by the recent PCI core cleanup, and the buggy PCI change has been already reverted. So basically we were scratching a wrong surface. OTOH, making the runtime PM calls symmetric for both probe and remove is more consistent, and maybe that's a sensible outcome.

2021-11-15ALSA: hda: intel: More comprehensive PM runtime setup for controller driverTakashi Iwai
Currently we haven't explicitly enable and allow/forbid the runtime PM at the probe and the remove phases of HD-audio controller driver, and this was the reason of a GPF mentioned in the commit e81478bbe7a1 ("ALSA: hda: fix general protection fault in azx_runtime_idle"); namely, even after the resources are released, the runtime PM might be still invoked by the bound graphics driver during the remove of the controller driver. Although we've fixed it by clearing the drvdata reference, it'd be also better to cover the runtime PM issue more properly. This patch adds a few more pm_runtime_*() calls at the probe and the remove time for setting and cleaning up the runtime PM. Particularly, now more explicitly pm_runtime_enable() and _disable() get called as well as pm_runtime_forbid() call at the remove callback, so that a use-after-free should be avoided.

2021-11-10ALSA: hda: fix general protection fault in azx_runtime_idleKai Vehmanen
Fix a corner case between PCI device driver remove callback and runtime PM idle callback. Following sequence of events can happen: - at azx_create, context is allocated with devm_kzalloc() and stored as pci_set_drvdata() - user-space requests to unbind audio driver - dd.c:__device_release_driver() calls PCI remove - pci-driver.c:pci_device_remove() calls the audio driver azx_remove() callback and this is completed - pci-driver.c:pm_runtime_put_sync() leads to a call to rpm_idle() which again calls azx_runtime_idle() - the azx context object, as returned by dev_get_drvdata(), is no longer valid -> access fault in azx_runtime_idle when executing struct snd_card *card = dev_get_drvdata(dev); chip = card->private_data; if (chip->disabled || hda->init_failed) This was discovered by i915_module_load test with 5.15.0 based linux-next tree.

2021-11-10ALSA: hda: Free card instance properly at probe errorsTakashi Iwai
The recent change in hda-intel driver to allow repeated probes surfaced a problem that has been hidden until; the probe process in the work calls azx_free() at the error path, and this skips the card free process that eventually releases codec instances. As a result, we get a kernel WARNING like: snd_hda_intel 0000:00:1f.3: Cannot probe codecs, giving up ------------[ cut here ]------------ WARNING: CPU: 14 PID: 186 at sound/hda/hdac_bus.c:73 .... For fixing this, we need to call snd_card_free() instead of azx_free(). Additionally, the device drvdata has to be cleared, as the driver binding itself is still active. Then the PM and other driver callbacks will ignore the procedure.

2021-10-07ALSA: hda: intel: Allow repeatedly probing on codec configuration errorsTakashi Iwai
It seems that a few recent AMD systems show the codec configuration errors at the early boot, while loading the driver at a later stage works magically. Although the root cause of the error isn't clear, it's certainly not bad to allow retrying the codec probe in such a case if that helps. This patch adds the capability for retrying the probe upon codec probe errors on the certain AMD platforms. The probe_work is changed to a delayed work, and at the secondary call, it'll jump to the codec probing. Note that, not only adding the re-probing, this includes the behavior changes in the codec configuration function. Namely, snd_hda_codec_configure() won't unregister the codec at errors any longer. Instead, its caller, azx_codec_configure() unregisters the codecs with the probe failures *if* any codec has been successfully configured. If all codec probe failed, it doesn't unregister but let it re-probed -- which is the most case we're seeing and this patch tries to improve. Even if the driver doesn't re-probe or give up, it will go to the "free-all" error path, hence the leftover codecs shall be disabled / deleted in anyway.

2021-09-30ALSA: hda: Use position buffer for SKL+ againTakashi Iwai
The commit f87e7f25893d ("ALSA: hda - Improved position reporting on SKL+") changed the PCM position report for SKL+ chips to use DPIB, but according to Pierre, DPIB is no best choice for the accurate position reports and it often reports too early. The recommended method is rather the classical position buffer. This patch makes the PCM position reporting on SKL+ back to the position buffer again.

2021-09-30ALSA: hda: Reduce udelay() at SKL+ position reportingTakashi Iwai
The position reporting on Intel Skylake and later chips via azx_get_pos_skl() contains a udelay(20) call for the capture streams. A call for this alone doesn't sound too harmful. However, as the pointer PCM ops is one of the hottest path in the PCM operations -- especially for the timer-scheduled operations like PulseAudio -- such a delay hogs CPU usage significantly in the total performance. The code there was taken from the original code in ASoC SST Skylake driver blindly. The udelay() is a workaround for the case where the reported position is behind the period boundary at the timing triggered from interrupts; applications often expect that the full data is available for the whole period when returned (and also that's the definition of the ALSA PCM period). OTOH, HD-audio (legacy) driver has already some workarounds for the delayed position reporting due to its relatively large FIFO, such as the BDL position adjustment and the delayed period-elapsed call in the work. That said, the udelay() is almost superfluous for HD-audio driver unlike SST, and we can drop the udelay(). Though, the current code doesn't guarantee the full period readiness as mentioned in the above, but rather it checks the wallclock and detects the unexpected jump. That's one missing piece, and the drop of udelay() needs a bit more sanity checks for the delayed handling. This patch implements those: the drop of udelay() call in azx_get_pos_skl() and the more proper check of hwptr in azx_position_ok(). The latter change is applied only for the case where the stream is running in the normal mode without no_period_wakeup flag. When no_period_wakeup is set, it essentially ignores the period handling and rather concentrates only on the current position; which implies that we don't need to care about the period boundary at all.

2021-08-17ALSA: hda: Drop workaround for a hang at shutdown againTakashi Iwai
The commit 0165c4e19f6e ("ALSA: hda: Fix hang during shutdown due to link reset") modified the shutdown callback of the HD-audio controller for working around a hang. Meanwhile, the actual culprit of the hang was identified to be the leftover active codecs that may interfere with the powered down controller somehow, but we took a minimal fix approach for 5.14, and that was the commit above. Now, since the codec drivers go runtime-suspend at shutdown for 5.15, we can revert the change and make sure that the full runtime-suspend is performed at shutdown of HD-audio controller again. This patch essentially reverts the commit above to restore the behavior.

2021-08-17ALSA: hda: Fix hang during shutdown due to link resetImre Deak
During system shutdown codecs may be still active, and resetting the controller->codec HW link in this state - based on the bug reporter's tests - leads to the shutdown sequence to get stuck. This happens at least on the reporter's KBL system with an ALC662 codec. For now fix the issue by skipping the link reset step.

It allows us to remove the superfluous mmap callback in HD-audio and its prepare_mmap redirection.
