2020-04-13ALSA: hda: Keep the controller initialization even if no codecs foundTakashi Iwai
Currently, when the HD-audio controller driver doesn't detect any codecs, it tries to abort the probe. But this abort happens at the delayed probe, i.e. the primary probe call already returned success, hence the driver is never unbound until user does so explicitly. As a result, it may leave the HD-audio device in the running state without the runtime PM. More badly, if the device is a HD-audio bus that is tied with a GPU, GPU cannot reach to the full power down and consumes unnecessarily much power. This patch changes the logic after no-codec situation; it continues probing without the further codec initialization but keep the controller driver running normally.

2020-04-13ALSA: hda: Release resources at error in delayed probeTakashi Iwai
snd-hda-intel driver handles the most of its probe task in the delayed work (either via workqueue or via firmware loader). When an error happens in the later delayed probe, we can't deregister the device itself because the probe callback already returned success and the device was bound. So, for now, we set hda->init_failed flag and make the rest untouched until the device gets really unbound. However, this leaves the device up running, keeping the resources without any use that prevents other operations. In this patch, we release the resources at first when a probe error happens in the delayed probe stage, but keeps the top-level object, so that the PM and other ops can still refer to the object itself. Also for simplicity, snd_hda_intel object is allocated via devm, so that we can get rid of the explicit kfree calls.

2020-04-13ALSA: hda: Don't release card at firmware loading errorTakashi Iwai
At the error path of the firmware loading error, the driver tries to release the card object and set NULL to drvdata. This may be referred badly at the possible PM action, as the driver itself is still bound and the PM callbacks read the card object. Instead, we continue the probing as if it were no option set. This is often a better choice than the forced abort, too.

2020-04-08ALSA: hda: Add driver blacklistTakashi Iwai
The recent AMD platform exposes an HD-audio bus but without any actual codecs, which is internally tied with a USB-audio device, supposedly. It results in "no codecs" error of HD-audio bus driver, and it's nothing but a waste of resources. This patch introduces a static blacklist table for skipping such a known bogus PCI SSID entry.

2020-01-11ALSA: hda: Rename back to dmic_detect optionTakashi Iwai
We've got quite a few bug reports showing the SOF driver being loaded unintentionally recently, and the reason seems to be that users didn't know the module option change: with the recent kernel, a new option dsp_driver=1 has to be passed to a new module snd-intel-dspcfg instead of snd_hda_intel.dmic_detect=0 option. That is, actually there are two tricky things here: - We changed the whole detection in another module and another option semantics. - The existing option for skipping the DSP probe was also renamed. For avoiding the confusion and giving user more hint, this patch reverts the renamed option dsp_driver back to dmic_detect for snd-hda-intel module, and show the warning about the module option change when the non-default value is passed.

2019-12-23ALSA: hda - Apply sync-write workaround to old Intel platforms, tooTakashi Iwai
Klaus Ethgen reported occasional high CPU usages in his system that seem caused by HD-audio driver. The perf output revealed that it's in the unsolicited event handling in the workqueue, and the problem seems triggered by some communication stall between the controller and the codec at the runtime or system resume. Actually a similar phenomenon was seen in the past for other Intel platforms, and we already applied the workaround to enforce sync-write for CORB/RIRB verbs for Skylake and newer chipsets (commit 2756d9143aa5 "ALSA: hda - Fix intermittent CORB/RIRB stall on Intel chips"). Fortunately, the same workaround is applicable to the old chipset, and the experiment showed the positive effect. Based on the experiment result, this patch enables the sync-write workaround for all Intel chipsets. The only reason I hesitated to apply this workaround was about the possibly slightly higher CPU usage. But if the lack of sync causes a much severer problem even for quite old chip, we should think this would be necessary for all Intel chips.

Now most of the get_response handling became quite similar between HDA-core and legacy drivers, and the only differences are: - the handling of extra-long polling delay for some codecs - the debug message for the stalled communication and both are worth to share in the common code. This patch unifies the code into snd_hdac_bus_get_response(), and use this from the legacy get_response callback. It results in a good amount of code reduction in the end.

For distributions, we need one place where we can decide which driver will be activated for the auto-configation of the Intel's HDA hardware with DSP. Actually, we cover three drivers: * Legacy HDA * Intel SST * Intel Sound Open Firmware (SOF) All those drivers registers similar PCI IDs, so the first driver probed from the PCI stack can win. But... it is not guaranteed that the correct driver wins. This commit changes Intel's NHLT ACPI module to a common DSP probe module for the Intel's hardware. All above sound drivers calls this code. The user can force another behaviour using the module parameter 'dsp_driver' located in the 'snd-intel-dspcfg' module. This change allows to add specific dmi checks for the specific systems.

2019-10-21ALSA: hda: Allow HDA to be runtime suspended when dGPU is not bound to a driverKai-Heng Feng
Nvidia proprietary driver doesn't support runtime power management, so when a user only wants to use the integrated GPU, it's a common practice to let dGPU not to bind any driver, and let its upstream port to be runtime suspended. At the end of runtime suspension the port uses platform power management to disable power through _OFF method of power resource, which is listed by _PR3. After commit b516ea586d71 ("PCI: Enable NVIDIA HDA controllers"), when the dGPU comes with an HDA function, the HDA won't be suspended if the dGPU is unbound, so the power resource can't be turned off by its upstream port driver. Commit 37a3a98ef601 ("ALSA: hda - Enable runtime PM only for discrete GPU") only allows HDA to be runtime suspended once GPU is bound, to keep APU's HDA working. However, HDA on dGPU isn't that useful if dGPU is not bound to any driver. So let's relax the runtime suspend requirement for dGPU's HDA function, to disable the power source to save lots of power.

2019-08-27ALSA: hda - Allow runtime PM for controller if component notifier is usedTakashi Iwai
Currently we disallow the runtime PM of the HD-audio controller if it's bound with HDMI/DP on Nvidia / AMD unless it's for dGPU. This is for keeping the link up to get the proper notification for ELD hotplug. As explained in the commit 37a3a98ef601 ("ALSA: hda - Enable runtime PM only for discrete GPU"), this keep-power-up behavior is rather a stop-gap solution until the ELD notification via audio component. And now we finally got the audio component for these graphics drivers via commit ade49db337a9 ("ALSA: hda/hdmi - Allow audio component for AMD/ATI and Nvidia HDMI"), so it's time to change. This patch makes HD-audio controller again runtime-suspendable when the device gets bound with audio component in HDMI codec driver. For making it easier to access from the codec driver, move the flag into the common hda_bus object instead of hda_intel flag. Also rename it to keep_power, to indicate the actual meaning.

2019-08-08ALSA: hda: Direct MMIO accessesTakashi Iwai
HD-audio drivers access to the mmio registers indirectly via the corresponding bus->io_ops callbacks. This is because some platform (notably Tegra SoC) requires the word-aligned access. But it's rather a rare case, and other platforms suffer from the penalties by indirect calls unnecessarily. This patch is an attempt to optimize and cleanup for this situation. Now the special aligned access is used only when a new kconfig CONFIG_SND_HDA_ALIGNED_MMIO is set. And the HD-audio core itself provides the aligned MMIO access helpers instead of the driver side. If Kconfig isn't set (as default), the standard helpers like readl() or writel() are used directly. A couple of places in ASoC Intel drivers have the access via io_ops reg_writel(), and they are replaced with the direct writel() calls. And now with this patch, the whole bus->io_ops becomes empty, so it's dropped completely. The bus initialization functions are changed accordingly as well to drop the whole bus->io_ops.

2019-08-08ALSA: hda: Remove page allocation redirectionTakashi Iwai
The HD-audio core allocates and releases pages via driver's specific dma_alloc_pages and dma_free_pages ops defined in bus->io_ops. This was because some platforms require the uncached pages and the handling of page flags had to be done locally in the driver code. Since the recent change in ALSA core memory allocator, we can simply pass SNDRV_DMA_TYPE_DEV_UC for the uncached pages, and the only difference became about this type to be passed to the core allocator. That is, it's good time for cleaning up the mess. This patch changes the allocation code in HD-audio core to call the core allocator directly so that we get rid of dma_alloc_pages and dma_free_pages io_ops. If a driver needs the uncached pages, it has to set bus->dma_type right after the bus initialization. This is merely a code refactoring and shouldn't bring any behavior changes.

A long-time problem on the recent AMD chip (X370, X470, B450, etc with PCI ID 1022:1457) with Realtek codecs is the crackled or distorted sound for capture streams, as well as occasional playback hiccups. After lengthy debugging sessions, the workarounds we've found are like the following: - Set up the proper driver caps for this controller, similar as the other AMD controller. - Correct the DMA position reporting with the fixed FIFO size, which is similar like as workaround used for VIA chip set. - Even after the position correction, PulseAudio still shows mysterious stalls of playback streams when a capture is triggered in timer-scheduled mode. Since we have no clear way to eliminate the stall, pass the BATCH PCM flag for PA to suppress the tsched mode as a temporary workaround. This patch implements the workarounds. For the driver caps, it defines a new preset, AXZ_DCAPS_PRESET_AMD_SB. It enables the FIFO- corrected position reporting (corresponding to the new position_fix=6) and enforces the SNDRV_PCM_INFO_BATCH flag. Note that the current implementation is merely a workaround. Hopefully we'll find a better alternative in future, especially about removing the BATCH flag hack again.

2019-07-31ALSA: hda/intel: stop probe if DMICS are detected on Skylake+ platformsPierre-Louis Bossart
The legacy HD-Audio driver cannot handle Skylake+ platforms with digital microphones. For those platforms, the SOF or SST drivers need to be used. This patch provides an automatic way of detecting the presence of DMICs using NHTL information reported by the BIOS. A kernel kconfig option or a kernel module parameter provide an opt-in means of stopping the probe. The kernel would then look for an alternate driver registered for the same PCI ID to probe. With this capability, distros no longer have to blacklist snd-hda-intel, but still need to make sure the SOF/SST drivers are functional by providing the relevant firmware and topology files in /lib/firmware/intel The coexistence between SOF and SST drivers and their dynamic detection is not addressed by this patch, different mechanisms need to be used, e.g. DMI-based quirks.

2019-07-25ALSA: hda - Fix intermittent CORB/RIRB stall on Intel chipsTakashi Iwai
It turned out that the recent Intel HD-audio controller chips show a significant stall during the system PM resume intermittently. It doesn't happen so often and usually it may read back successfully after one or more seconds, but in some rare worst cases the driver went into fallback mode. After trial-and-error, we found out that the communication stall seems covered by issuing the sync after each verb write, as already done for AMD and other chipsets. So this patch enables the write-sync flag for the recent Intel chips, Skylake and onward, as a workaround. Also, since Broxton and co have the very same driver flags as Skylake, refer to the Skylake driver flags instead of defining the same contents again for simplification.
