ac97: Fix device real time priority issue
- Add allow sched_setscheduler call in seccomp policy - Change the real time priority constant AUDIO_THREAD_RTPRIO to 10 to match all other clients' priority. Run the following commands to test 1. ulimit -r 10 2. crosvm run -r ./vm_rootfs.img -c 1 -m 1024 -s /run --cid 5 --host_ip \ 100.115.92.25 --netmask 255.255.255.252 --cras-audio \ --params="snd_intel8x0.inside_vm=1 snd_intel8x0.ac97_clock=48000" \ --mac d2:47:f7:c5:9e:53 ./vm_kernel 3. aplay -Dhw:0,0 -f dat /dev/zero 4. ps -AT -o comm,rtprio | grep crosvm should see a thread running with rtprio=10 BUG=chromium:983533 BUG=b:138262556 TEST=Test with eve (x86_64) and bob (arm) Change-Id: Idc3711d03d716741f7cefd9a89b14ae4c20c2033 Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/1729089 Tested-by: kokoro <noreply+kokoro@google.com> Tested-by: Chih-Yang Hsia <paulhsia@chromium.org> Reviewed-by: Dylan Reid <dgreid@chromium.org> Commit-Queue: Chih-Yang Hsia <paulhsia@chromium.org>
