Bug#774914: firmware-linux-nonfree: Include the intel sst firmwares required for audio on Bay Trail
[My appologies if you received an earlier draft of this. I accidentally
hit "Send"...]
Hi,

On a Bay Trail tablet I get this error:

The fimrware is available upstream:
http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/intel
And comes with this license:

Kernel: Linux 3.19.0-rc3-ao2 (SMP w/2 CPU cores)
Note that this is not a Debian kernel. AFAIK, Jessie will ship with
3.16.7-cktX which after enabling the relevant Alsa modules (#773835)
requests a different file. I haven't tested with kernels more recent
than 3.16. While they may work with the firmware files from linux-
firmware.git I cannot reproduce this on 3.16.
Running the current kernel from unstable
# uname -a
Linux v8p 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt7-1 (2015-03-01) x86_64
GNU/Linux
which already has a fix for #773835 I get the following in dmesg without
the firmware files:
[ 3.450588] sst-acpi 80860F28:00: firmware: failed to load
intel/fw_sst_0f28.bin-i2s_master (-2)
[ 3.450605] sst-acpi 80860F28:00: Direct firmware load failed with
error -2
linux-firmware.git does not contain this file. The closest match is
indeed intel/fw_sst_0f28.bin-48kHz_i2s_master but if I rename that I
get this:

The same behavior was also reported in a Ubuntu forum post [1] which
suggests using the firmware files from Chromium OS [2]. If I place
those files in /lib/firmware/intel the driver gets a little farther:

A little later the system runs into a number of issues (full dmesg
attached):

[ 14.579173] [sched_delayed] sched: RT throttling activated
I believe this is a manifestion of incorrect dynamic irq allocation
causing all sorts of GPIO/SDIO-using hardware to break (see e.g. [3]).
A patch by Thomas Gleixner is available at [4] which IIRC has already
been applied upstream in later kernel releases. I'll test the patch and
file a new bug report to track that issue.

Rene
