* ALSA: compress: Fix stop handling on compressed capture streamsCharles Keepax2019-02-051-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | It is normal user behaviour to start, stop, then start a stream again without closing it. Currently this works for compressed playback streams but not capture ones. The states on a compressed capture stream go directly from OPEN to PREPARED, unlike a playback stream which moves to SETUP and waits for a write of data before moving to PREPARED. Currently however, when a stop is sent the state is set to SETUP for both types of streams. This leaves a capture stream in the situation where a new start can't be sent as that requires the state to be PREPARED and a new set_params can't be sent as that requires the state to be OPEN. The only option being to close the stream, and then reopen. Correct this issues by allowing snd_compr_drain_notify to set the state depending on the stream direction, as we already do in set_params.

* ALSA: hda - Serialize codec registrationsTakashi Iwai2019-02-011-0/+1
| | | | | | | | | | | | | | | | In the current code, the codec registration may happen both at the codec bind time and the end of the controller probe time. In a rare occasion, they race with each other, leading to Oops due to the still uninitialized card device. This patch introduces a simple flag to prevent the codec registration at the codec bind time as long as the controller probe is going on. The controller probe invokes snd_card_register() that does the whole registration task, and we don't need to register each piece beforehand.

There's a couple of things going on, the main one is that we found some issues with not deferring probe when we should, causing us to skip some driver initialization. The fixes for this then in turn exposed some issues with how we were searching for components which had previously gone unnoticed due to the original issue. There's also been the normal driver specific stuff and there's been what looks like several batches of automated scanning for issues which have generated quite a large set of smaller fixes for potential crashes and missed error handling.
| * ASoC: soc-core: fix init platform memory handlingCurtis Malainey2019-01-141-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | snd_soc_init_platform initializes pointers to snd_soc_dai_link which is statically allocated and it does this by devm_kzalloc. In the event of an EPROBE_DEFER the memory will be freed and the pointers are left dangling. snd_soc_init_platform sees the dangling pointers and assumes they are pointing to initialized memory and does not reallocate them on the second probe attempt which results in a use after free bug since devm has freed the memory from the first probe attempt. Since the intention for snd_soc_dai_link->platform is that it can be set statically by the machine driver we need to respect the pointer in the event we did not set it but still catch dangling pointers. The solution is to add a flag to track whether the pointer was dynamically allocated or not. Signed-off-by: Curtis Malainey <cujomalainey@chromium.org> Signed-off-by: Mark Brown <broonie@kernel.org>
* | ALSA: HD-Audio: SKL+: force HDaudio legacy or SKL+ driver selectionPierre-Louis Bossart2018-12-191-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For HDaudio and Skylake drivers, add module parameter "pci_binding" When pci_binding == 0 (AUTO), the PCI class/subclass info is used to select drivers based on the presence of the DSP. pci_binding == 1 (LEGACY) forces the use of the HDAudio legacy driver, even if the DSP is present. pci_binding == 2 (ASOC) forces the use of the ASOC driver. The information on the DSP presence is bypassed. The value for the module parameter needs to be identical for both drivers. This parameter is intended as a back-up solution if the automatic detection fails or when the DSP usage fails. Such cases should be reported on the alsa-devel mailing list for analysis.

There's also a large part of the diff from a merge of the DaVinci and OMAP directories, along with some active development there: - Preparatory work from Morimoto-san for merging the audio-graph and audio-graph-scu cards. - A merge of the TI OMAP and DaVinci directories, the OMAP product line has been merged into the DaVinci product line so there is now a lot of IP sharing which meant that the split directories just got in the way. This has pulled in a few architecture changes as well. - A big cleanup of the Maxim MAX9867 driver from Ladislav Michl. - Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx I2S controllers.

This patch is a big surgery for addressing the complexity and the possible unbalance. Basically the patch changes the display PM in the following ways: - Both HD-audio controller and codec drivers call a single helper, snd_hdac_display_power(). (Formerly, the display power control from a codec was done indirectly via link_power bus ops.) - snd_hdac_display_power() receives the codec address index. For turning on/off from the controller, pass HDA_CODEC_IDX_CONTROLLER. - snd_hdac_display_power() doesn't manage refcounts any longer, but keeps the power status in bitmap. If any of controller or codecs is turned on, the function updates the DRM power state via get_power() or put_power(). Also this refactor allows us more cleanup: - The link_power bus ops is dropped, so there is no longer indirect management, as mentioned in the above. - hdac_device link_power_control flag is moved to hda_codec display_power_control flag, as it's only for HDA legacy.

This list is cleared when the card is rebind successfully or when the card is unregistered from machine driver. This list of unbind cards are tried to bind once again after every new component is successfully added, giving a fair chance for card bind to be successful.

If all Codec/CPU/Platform are replaced into snd_soc_dai_link_component style, we can remove legacy complex style.

| * | ASoC: soc-core: use snd_soc_dai_link_component for platformKuninori Morimoto2018-08-311-0/+2

We don't have multicpu support yet, but in the future we will. In such case, we can use snd_soc_dai_link_component for both cpu/codec. Then the code will be more simple and readble. As next step, we want to use it for platform, too. This patch adds snd_soc_dai_link_component style for platform. We might have multiplatform support in the future, but we don't know yet. To avoid un-known issue / complex code, this patch supports just single-platform as 1st step. If we could use snd_soc_dai_link_component for all CPU/Codec/Platform, we will switch to new style, and remove legacy code. This is prepare for it.

| * | ASoC: Intel: common: add table for HDA-based platformsPierre-Louis Bossart2018-08-281-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Expose a table containing machine driver information for HDAudio-based platforms handled by ASoC on Intel hardware. We only set constant values that are valid across multiple platforms. The firmware name used by the DSP will be set dynamically for each platform. The table is made of a single entry for now, if we need more complicated set-up where HDAudio is mixed with ACPI-enumerated devices (I2C, SoundWire) then we'd expect the differentiation to be handled through information provided by the BIOS (as done for KBL Chromebooks).

| | * | sound: don't call skl_init_chip() to reset intel skl socYu Zhao2018-09-121-0/+1
| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Internally, skl_init_chip() calls snd_hdac_bus_init_chip() which 1) sets bus->chip_init to prevent multiple entrances before device is stopped; 2) enables interrupt. We shouldn't use it for the purpose of resetting device only because 1) when we really want to initialize device, we won't be able to do so; 2) we are ready to handle interrupt yet, and kernel crashes when interrupt comes in. Rename azx_reset() to snd_hdac_bus_reset_link(), and use it to reset device properly.
