CSC3551 and devices missing related _DSD bits

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Takashi (and all others),

We're beginning to encounter more and more laptops from ASUS in the ROG range 
where the bass speakers are connected to a cirrus amp, and the driver for 
cirrus is unable to pick this up due to being missing a _DSD section in the 
ACPI (SSDT). I've emailed engineers at ASUS I have contact with about this but 
it is unlikely that we will see corrections for each and every model + variant 
they have. The models we have seen so far are:
- GX650P
- GU604V
- GA402X
And there have been numerous forum postings in various places with the exact 
same issue for other models from ASUS that are not in the ROG group I deal 
with - oh and also some Lenovo and HP devices also.

Some of the logs are:

[    5.542312] Serial bus multi instantiate pseudo device driver CSC3551:00:

and:

So there are SPI connected, and I2C connected.

Alex has already submitted the related patch_realtek work for the GU604V and 
no doubt there will be some follow up patches from myself or others for the 
other models. Alex has attempted to patch the Cirrus related parts in kernel 
direct with:
1. https://github.com/bno1/linux-xanmod-gu604/blob/acpi-hack/
patch03_gu604v_speaker_acpi_hack.patch
2. https://github.com/bno1/linux-xanmod-gu604/blob/acpi-hack/
patch04_gu604v_spi_cs_gpio_hack.patch
both of these patches have been tested and working for over a week.

>From what I see the patch04_gu604v_spi_cs_gpio_hack patch needs to shift to 
the cirrus driver sound/pci/hda/cs35l41_hda.c, and that driver must now have a 
quirk table - unless we can somehow add the cirrus related bits to the realtek 
code? I've personally not played with this beyond keeping an eye on it all and 
am reluctant to begin work on a solution until I've had some input on the 
direction it should take.

In any case, this is not an isolated issue and we could benefit from putting 
in place some quirk or similar to accommodate for laptops where the vendor for 
some reason does not include the _DSD parts for use with the cirrus driver. 
The trend is looking so far like this practice will continue regardless of the 
vendor.
