Removes conditionals and sets corbsize, with reset
Hi,
13.5-RELEASE would not initialize the AMD W2100's DisplayPort (HDMI) audio:
hdac0: <ATI (0xaab0) HDA Controller> mem 0xf1b40000-0xf1b43fff irq 36 at device
0.1 on pci3
hdac0: hdac_get_capabilities: Invalid corb size (0)
device_attach: hdac0 attach returned 6
In researching, I found this series of suggested code changes by avg@:
https://freebsd-current.freebsd.narkive.com/QZiPCBtN/amd64-panic-snd-hda-hdac-get-capabilities-invalid-c
orb-size-0
I can confirm that it fixes the issue -- it now works flawlessly:
hdacc0: <ATI R6xx HDA CODEC> at cad 0 on hdac0
hdaa0: <ATI R6xx Audio Function Group> at nid 1 on hdacc0

hdac0: <ATI (0xaab0) HDA Controller> mem 0xf1b40000-0xf1b43fff irq 36 at device
0.1 on pci3
hdacc0: <ATI R6xx HDA CODEC> at cad 0 on hdac0
hdaa0: <ATI R6xx Audio Function Group> at nid 1 on hdacc0
pcm0: <ATI R6xx (HDMI)> at nid 3 on hdaa0
pcm1: <ATI R6xx (HDMI)> at nid 5 on hdaa0
Diffs attached:
I heeded the advice in that thread and removed the corbsize and rirbsize checks
on my system.
This is the "just-set-256.diff", which has shown no issues in testing.
However, I also thought it may be wanted to only set corbsize/rirbsize in the
failure condition, and so
I also made "keep-ifs.diff", which also works fine.
Only one of these diffs is needed. I am open to refining further if need be.
All credit is avg@'s.
Thanks.
