Since the recent change in CS35L41 codec requires the reference of acpi_dev handle, the current Kconfig may lead to a build breakage. Revert the Kconfig change and re-introduce the hard dependency on CONFIG_ACPI again as a temporary workaround.

When codec is unbound but not yet removed, in the eyes of snd_hdac_bus_process_unsol_events() it is still a valid target to delegate work to. Such behaviour may lead to use-after-free errors. Address by verifying if codec is actually registered. Signed-off-by:

By default, the driver will automatically load DSP firmware for the amps, if available. Adding this option allows the autoload to be optional, which allows for different configurations. Signed-off-by:

This is required to support CS35L41 calibration. By default, speaker protection firmware will be loaded, if available. However, different firmware is required to run the calibration sequence, so it is necessary to add support to be able to unload, switch and reload firmware. This patch adds 2 ALSA Controls for each amp: "DSP1 Firmware Load" "DSP1 Firmware Type" "DSP1 Firmware Load" can be used to unload and load the firmware. "DSP1 Firmware Type" can be used to switch the target firmware to be loaded by "DSP1 Firmware Load" Since loading firmware can add new ALSA controls, it is necessary to ensure the firmware loading is run asynchronously from the ALSA control itself to prevent deadlocks. Note: When switching between firmwares, an ALSA control is only added if it has not previously existed. If it had existed previously, it will be re-enabled instead. Signed-off-by:

The config sequences for running with and without firmware and DSP are different. The original behavior assumed that we would only run without DSP only in the case where firmware load failed. This meant the non-firmware sequence was written with the assumtion that various registers would be set to their default value. However, to support the ability to unload the firmware, the non-firmware register sequence must be updated to update all required registers, including values that would be defaulted, in case the firmware sequence, which could have already run, has changed their value.

CS35L41 supports hibernation during suspend when using DSP firmware. When the driver suspends it will hibernate the part, if firmware is running, and resume will wake from hibernation. CS35L41 driver will suspend/resume when requested by hda driver. Note that suspend/resume and hibernation is only supported when firmware is running. Signed-off-by:

Merge tag 'asoc-v5.20' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next ASoC: Updates for v5.20 This is a big release thus far and there will probably be more changes to come, it's a combination of a larger than usual crop of new drivers and some subsysetm wide cleanups from Charles rather than anything structural. The SOF and Intel DSP code both also continue to be very actively developed. - Restructing of the set_fmt() callbacks to be specified in terms of the device rather than with semantics depending on if the device is supposed to be a CODEC or SoC, making things clearer in situations like CODEC to CODEC links. - Clean up of the way we flag which DAI naming scheme we use to reflect the progress that's been made modernising things. - Merge of more of the Intel AVS driver stack, including some board integrations. - New version 4 mechanism for communication with SOF DSPs. - Suppoort for dynamically selecting the PLL to use at runtime on i.MX platforms. - Improvements for CODEC to CODEC support in the generic cards. - Support for AMD Jadeite and various machines, Intel MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and WAS883x, and Texas Instruments TAS2780.

When the driver fails in snd_card_register() at probe time, it will free the 'bcd2k->midi_out_urb' before killing it, which may cause a UAF bug. The following log can reveal it: [ 50.727020] BUG: KASAN: use-after-free in bcd2000_input_complete+0x1f1/0x2e0 [snd_bcd2000] [ 50.727623] Read of size 8 at addr ffff88810fab0e88 by task swapper/4/0 [ 50.729530] Call Trace: [ 50.732899] bcd2000_input_complete+0x1f1/0x2e0 [snd_bcd2000] Fix this by adding usb_kill_urb() before usb_free_urb().

There are two bugs that have to do with when we copy the payload: size = simple_write_to_buffer(ipc4_msg->data_ptr, priv->max_msg_size, ppos, buffer, count); The value of "*ppos" was supposed to be zero but it is sizeof(ipc4_msg->header_u64) so it will copy the data into the middle of the "ipc4_msg->data_ptr" buffer instead of to the start. The second problem is "buffer" should be "buffer + sizeof(ipc4_msg->header_u64)". This function is used for fuzz testing so the data is normally random and this bug likely does not affect anyone very much. In this context, it's simpler and more appropriate to use copy_from_user() instead of simple_write_to_buffer() so I have re-written the function.

Some Laptops use a number of gpios to define which vendor is used for a particular laptop. Different coefficient files are used for different vendors. Signed-off-by:
-
Stefan Binding authored
To be able to support different firmwares and tuning for different models, the driver needs to be able to load a different firmware and coefficient file based on its Subsystem ID. The driver attempts to load the firmware in the following order: /lib/firmware/cirrus/cs35l41-dsp1-<fw-type>-<ssid>-dev<#>.wmfw /lib/firmware/cirrus/cs35l41-dsp1-<fw-type>-<ssid>.wmfw /lib/firmware/cirrus/cs35l41-dsp1-<fw-type>.wmfw Signed-off-by:

This patch adds support for the CS35L41 DSP. The DSP allows for extra features, such as running speaker protection algorithms and hibernations. To utilize these features, the driver must load firmware into the DSP, as well as various tuning files which allow for customization for specific models.

The cs35l41 part contains a DSP which is able to run firmware. The cs_dsp library can be used to control the DSP. These controls can be exposed to userspace using ALSA controls. This library adds apis to be able to interface between cs_dsp and hda drivers and expose the relevant controls as ALSA controls.

Use atomic_try_cmpxchg instead of atomic_cmpxchg (*ptr, old, new) == old in ep_state_update. x86 CMPXCHG instruction returns success in ZF flag, so this change saves a compare after cmpxchg (and related move instruction in front of cmpxchg). No functional change intended. Signed-off-by:
