[Nouveau] [PATCH] drm/nv50: decode PGRAPH status registers on TLB flush fail
Now it outputs:
nouveau E[ PGRAPH][0000:02:00.0] PGRAPH TLB flush idle timeout fail
nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_STATUS: BUSY DISPATCH VFETCH
CCACHE_UNK4 STRMOUT_GSCHED_UNK5 UNK14XX UNK1CXX CLIPID ZCULL ENG2D UNK34XX
TPRAST TPROP ROP (0x011fde03)
nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_VSTATUS: CCACHE (0x00145b4d)
(0x0000002d) ENG2D ROP (0x0034db40)
instead of:
[drm] nouveau 0000:02:00.0: PGRAPH TLB flush idle timeout fail: 0x011fde03
0x00145b4d 0x0000002d 0x0034db40
Based on envytools docs.
