2019-11-06ALSA: pcm: Create proc files only for non-empty preallocationsTakashi Iwai1-1/+2
It makes little sense to create prealloc proc files for streams that have the zero max size, which is a typical case for vmalloc buffers. Skip the proc file creations to save resources in such a case. Link: https://lore.kernel.org/r/20191105191007.18150-3-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2019-11-06ALSA: pcm: Warn if doubly preallocatedTakashi Iwai1-0/+2
Warn if snd_pcm_lib_preallocate_pages*() is applied to the stream that has already the preallocated buffers and skip the allocation. It's a clearly a driver bug. Link: https://lore.kernel.org/r/20191105191007.18150-2-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2019-11-06ALSA: pcm: Handle special page mapping in the default mmap handlerTakashi Iwai1-1/+13
When a driver needs to deal with a special buffer like a SG or a vmalloc buffer, it has to set up the PCM page ops explicitly for the corresponding helper function. This is rather error-prone and many people forgot or incorrectly used it. For simplifying the call patterns and avoiding such a potential bug, this patch enhances the PCM default mmap handler to check the (pre-)allocated buffer type and handles the page gracefully depending on the buffer type. If the PCM page ops is given, the ops is still used in a higher priority. The new code path is only for the default (NULL page ops) case.

2019-11-06ALSA: memalloc: Add vmalloc buffer allocation supportTakashi Iwai1-4/+16
This patch adds the vmalloc buffer support to ALSA memalloc core. A new type, SNDRV_DMA_TYPE_VMALLOC was added. The vmalloc buffer has been already supported in the PCM via a few own helper functions, but the user sometimes get confused and misuse them. With this patch, the whole buffer management is integrated into the memalloc core, so they can be used in a sole common way.

2019-11-06ALSA: memalloc: Allow NULL device for SNDRV_DMA_TYPE_CONTINUOUS typeTakashi Iwai1-3/+8
Currently we pass the artificial device pointer to the allocation helper in the case of SNDRV_DMA_TYPE_CONTINUOUS for passing the GFP flags. But all common cases are the allocations with GFP_KERNEL, and it's messy to put this in each place. In this patch, the memalloc core helper is changed to accept the NULL device pointer and it treats as the default mode, GFP_KERNEL, so that all callers can omit the complex argument but just leave NULL.

2019-11-05ALSA: hda: Disable regmap internal lockingTakashi Iwai1-0/+1
Since we apply the own mutex (bus->cmd_mutex) in HDA core side, the internal locking in regmap is superfluous. This patch adds the flag to indicate that. Also, an infamous side-effect by this change is that it disables the regmap debugfs, too, and this is seen rather good; the regmap debugfs isn't quite useful for HD-audio as it provides the very sparse registers and its debugfs access tends to lead to the way too high resource usages or sometimes hang up. So it'd be rather safe to disable it altogether.

2019-11-04ALSA: pcm: Fix missing check of the new non-cached buffer typeTakashi Iwai1-1/+2
The check for the mmap support via hw_support_mmap() function misses the case where the device is with SNDRV_DMA_TYPE_DEV_UC, which should have been treated equally as SNDRV_DMA_TYPE_DEV. Let's fix it. Note that this bug doesn't hit any practical problem, because SNDRV_DMA_TYPE_DEV_UC is used only for x86-specific drivers (snd-hda-intel and snd-intel8x0) for the specific platforms that need the non-cached buffers. And, on such platforms, hw_support_mmap() already returns true in anyway. That's the reason I didn't put Cc-to-stable mark here. This is only for any theoretical future extension.

2019-11-02ALSA: bebob: link the order of establishing connections and Syt-match clock modeTakashi Sakamoto1-29/+22
Originally BeBeB ASICs and firmware supports clock mode to synchronizing to syt field of received isoc packet. This mode is known as 'SYT Match' slightly described in IEC 61883-6 (but no detail mechanisms). In this mode, drivers can control sampling clock in device. Driver for Windows and macOS uses this feature to perform synchronization for devices on the same bus. In this mode, a plug of Music subunit for synchronization is connected to a plug of isoc unit for incoming packet streaming, then the order to establish connections is INPUT_PLUG first, OUTPUT_PLUG second. This commit implements the above. Actually each device works with its own clock for sampling, therefore the original design is hardly implemented to vendor's products.

2019-11-02ALSA: bebob: expand delay of start for IR context just for version 3 firmwareTakashi Sakamoto1-4/+10
As long as I investigated, there's some cases about the delay for device between establishing OUTPUT_PLUG and transmitting first isoc packet. For devices which support BeBoB protocol version 1 can transmit the packet within several hundred milliseconds, while for devices which support BeBoB protocol version 3 can transmit the packet within 2 seconds. Devices with protocol version 1: * Edirol FA-66 * Yamaha GO46 * Terratec Phase x24 FW * M-Audio FireWire AudioPhile * M-Audio FireWire Solo * M-Audio FireWire 1814 * M-Audio FireWire 410 * Focusrite Saffire Pro 26 I/O Devices with protocol version 3: * M-Audio Profire Lightbridge * Behringer FCA610 * Phonic Firefly 202 At present ALSA bebob driver postpones starting IR context during 1.5 sec for all of supported devices. The delay is too long for devices with protocol version 1, while it's not enough for devices with protocol version 3. This commit improves the delay for these protocols.

2019-11-02ALSA: bebob: expand sleep just after breaking connections for protocol version 1Takashi Sakamoto1-5/+6
As long as I investigated, some devices with BeBoB protocol version 1 can be freezed during several hundreds milliseconds after breaking connections. When accessing during the freezed time, any transaction is corrupted. In the worst case, the device is going to reboot. I can see this issue in: * Roland FA-66 * M-Audio FireWire Solo This commit expands sleep just after breaking connections to avoid the freezed time as much as possible. I note that the freeze/reboot behaviour is similar to below models: * Focusrite Saffire Pro 10 I/O * Focusrite Saffire Pro 26 I/O The above models certainly reboot after breaking connections.

This is an alternative fix attemp for the issue reported in the commit caa8422d01e9 ("ALSA: hda: Flush interrupts on disabling") that was reverted later due to regressions. Instead of tweaking the hardware disablement order and the enforced irq flushing, do calling cancel_work_sync() of the unsol work early enough, and explicitly ignore the unsol events during the shutdown by checking the bus->shutdown flag.

This reverts commit caa8422d01e983782548648e125fd617cadcec3f. It turned out that this commit caused a regression at shutdown / reboot, as the synchronize_irq() calls seems blocking the whole shutdown. Also another part of the change about shuffling the call order looks suspicious; the azx_stop_chip() call disables the CORB / RIRB while the others may still need the CORB/RIRB update.

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 Feng1-1/+7
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.

All of the isoc context are processed in a callback for an isoc context of IRQ target. The IRQ target is automatically selected from a list of AMDTP streams, thus users of AMDTP domain should add an AMDTP stream for IT context at least. The reason to select IT context as IRQ target is that the IT context runs on local 1394 OHCI controller and it can be used as reliable, constant IRQ generator. On the other hand, IR context can include skip cycle according to isoc packet transferred by device.

process context callback The aim of AMDTP domain is to process several isoc context in the same time. However, current implementation is against this idea because it flushes each isoc context in the end of processing context callback. This commit cancels it.

2019-10-18ASoC: SOF: control: return true when kcontrol values changeDragos Tarcatu1-8/+18
All the kcontrol put() functions are currently returning 0 when successful. This does not go well with alsamixer as it does not seem to get notified on SND_CTL_EVENT_MASK_VALUE callbacks when values change for (some of) the sof kcontrols. This patch fixes that by returning true for volume, switch and enum type kcontrols when values do change in put().

2019-10-18ASoC: stm32: sai: fix sysclk management on shutdownOlivier Moysan1-10/+11
The commit below, adds a call to sysclk callback on shutdown. This introduces a regression in stm32 SAI driver, as some clock services are called twice, leading to unbalanced calls. Move processing related to mclk from shutdown to sysclk callback. When requested frequency is 0, assume shutdown and release mclk.

2019-10-18ASoC: rsnd: Reinitialize bit clock inversion flag for every format settingJunya Monden1-0/+1
Unlike other format-related DAI parameters, rdai->bit_clk_inv flag is not properly re-initialized when setting format for new stream processing. The inversion, if requested, is then applied not to default, but to a previous value, which leads to SCKP bit in SSICR register being set incorrectly. Fix this by re-setting the flag to its initial value, determined by format.

2019-10-18ALSA: firewire-lib: tune the minimum available size of PCM periodTakashi Sakamoto1-1/+13
In IEC 61883-1/6, one isoc packet can transfer events up to the value of syt interval. This comes from the interval of isoc cycle. As 1394 OHCI controller can generate hardware IRQ per isoc packet, the interval is calculated as 125 usec. In IEC 61883-1/6, two ways of transmission is described; blocking and non-blocking methods. In blocking method, the sequence of packet includes 'empty' or 'NODATA' packets which include no events. In non-blocking method, the number of events per packet is variable up to the syt interval. This commit uses double of the value of syt interval as minimum available size of PCM period due to the above protocol design.

2019-10-18ALSA: firewire-lib: tune the maximum available size of PCM periodTakashi Sakamoto1-11/+18
Linux driver for 1394 OHCI controller voluntarily flushes isoc context when total size of accumulated context header reached PAGE_SIZE. This kicks tasklet for the isoc context. This is inconvenient to process runtime of PCM substream. This commit adds a restriction of the maximum size of PCM period to avoid this behaviour.

2019-10-18ALSA: firewire-lib: schedule hardware IRQ according to the size of PCM periodTakashi Sakamoto2-15/+58
ALSA IEC 61883-1/6 packet streaming engine controls 1394 OHCI controller to generate hardware IRQ for fixed number of isochronous packets (=16) since its first commit. This commit allow the engine to generate it for variable period according to the number of event to handle. For outgoing stream, internal calculator is used to check the accumulated events. For incoming stream, the number of data block in the packet of stream is used to check the accumulated events. When it's unavailable, fixed number of packet roughly calculated in advance is used instead of event counting.

This commit allows ALSA fireface driver to share PCM buffer size for both capture and playback PCM substream. When AMDTP domain starts for one of the PCM substream, buffer size of the PCM substream is stores to AMDTP domain structure. Some AMDTP streams have already run with the buffer size when another PCM substream starts, therefore the PCM substream has a constraint to its buffer size.
