The snd_soc_dai_ops structures is only stored in the ops field of a
snd_soc_dai_driver structure, so make the snd_soc_dai_ops structure

When we try to play and capture simultaneously we see that
interrupts are genrated but our handler is not being acknowledged,
After investigating further more in detail on this issue we found
that IRQ delivery via MSI from the ACP IP is unreliable and so sometimes
interrupt generated will not be acknowledged so MSI model shouldn't be used
and using legacy IRQs will resolve interrupt handling issue.
This patch replaces MSI interrupt handling with legacy IRQ model.
Issue can be reproduced easily by running below python script:
import subprocess
import time
import threading
def do2():
cmd = 'aplay -f dat -D hw:2,1 /dev/zero -d 1'
subprocess.call(cmd, stdin=subprocess.PIPE,
stderr=subprocess.PIPE, shell=True)
print('Play Done')
def run():
for i in range(1000):
do2()
def do(i):
cmd = 'arecord -f dat -D hw:2,2 /dev/null -d 1'
subprocess.call(cmd, stdout=subprocess.PIPE,
stderr=subprocess.PIPE, shell=True)
print(datetime.datetime.now(), i)
t = threading.Thread(target=run)
t.start()
for i in range(1000):
do(i)
t.join()
After applying this patch issue is resolved.

The acp3x raven driver skips the probing when the given device isn't
connected with I2S. This skip behavior itself is fine, but the driver
also emits an error message "Invalid ACP audio mode" with KERN_ERR.
This isn't nice since it appears on the boot screen even if a boot
splash is running, although this itself is no real error.
Downgrade the print level to KERN_INFO so that this message won't
appear on the console unnecessarily.

PME_EN state needs to restored to the value set by fmw.
For the devices which are not using I2S wake event which gets
enabled by PME_EN bit, keeping PME_EN enabled burns considerable amount
of power as it blocks low power state.
For the devices using I2S wake event, PME_EN gets enabled in fmw and the
state should be maintained after ACP Power On.

Simultaneous capture on dmic and headset mic is having
issue with high hw_level being reported.
Issue Can be reproduced by:
arecord -D hw:2,0 -f dat -d 60 /tmp/test0 &
arecord -D hw:2,2 -f dat -d 60 /tmp/test1 &
cat /proc/asound/card2/pcm?c/sub0/status
Actual issue is :
When we open one capture stream on one instance lets say I2S_SP and then
once again if we open other capture on other instance lets say I2S_BT while
first capture is in progress and when we try to read the status of both
running instances by below command cat /proc/asound/card2/pcm?c/sub0/status
we observe that avail_max is being doubled on first opened
capture(I2S_SP in the example).
This is because our previous implementation was like when any instance is
opened it gets initialized in dma_open irrespective of on what instance it
called open.
For example:
First I2S_SP called opened it initializes both SP/BT capture streams
irrespective of on which instance the stream opened.next time I2S_BT
called opened and it initializes both SP/BT this corrupts the behaviour .
So with this patch the stream gets initialized only on specific instance
when ever it gets opened calls hw_params.
This rectifies the issue.

We shouldn't assume CPU physical address we get from page_to_phys()
is same as DMA address we get from dma_alloc_coherent(). On x86_64,
we won't run into any problem with the assumption when dma_ops is

And it's most likely different from CPU physical address when AMD
