[Nouveau] [PATCH 01/10] 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_0: CCACHE (0x00145b4d)
nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_VSTATUS_1: (0x0000002d)
nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_VSTATUS_2: 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.

Mostly I was thinking we should probably have a: nv_printf(obj, lvl, fmt, args...) to replace the printk's which just does a continued print while still obeying the debug level?> > Based on envytools docs. > > Signed-off-by: Marcin Slusarz <marcin.slusarz at gmail.com> > --- > drivers/gpu/drm/nouveau/core/engine/graph/nv50.c | 78 ++++++++++++++++++++- > 1 files changed, 74 insertions(+), 4 deletions(-) > > diff --git a/drivers/gpu/drm/nouveau/core/engine/graph/nv50.c b/drivers/gpu/drm/nouveau/core/engine/graph/nv50.c > index c93b525..f60aec9 100644 > --- a/drivers/gpu/drm/nouveau/core/engine/graph/nv50.c > +++ b/drivers/gpu/drm/nouveau/core/engine/graph/nv50.c > @@ -184,6 +184,62 @@ nv50_graph_tlb_flush(struct nouveau_engine *engine) > return 0; > } > > +static struct nouveau_bitfield nv50_pgraph_status[] = { > + { 1<<0, "BUSY" }, /* set when any bit is set */ > + { 1<<1, "DISPATCH" }, > + { 1<<2, "UNK2" }, > + { 1<<3, "UNK3" }, > + { 1<<4, "UNK4" }, > + { 1<<5, "UNK5" }, > + { 1<<6, "M2MF" }, > + { 1<<7, "UNK7" }, > + { 1<<8, "CTXPROG" }, > + { 1<<9, "VFETCH" }, > + { 1<<10, "CCACHE_UNK4" }, > + { 1<<11, "STRMOUT_GSCHED_UNK5" }, > + { 1<<12, "UNK14XX" }, > + { 1<<13, "UNK24XX_CSCHED" }, > + { 1<<14, "UNK1CXX" }, > + { 1<<15, "CLIPID" }, > + { 1<<16, "ZCULL" }, > + { 1<<17, "ENG2D" }, > + { 1<<18, "UNK34XX" }, > + { 1<<19, "TPRAST" }, > + { 1<<20, "TPROP" }, > + { 1<<21, "TEX" }, > + { 1<<22, "TPVP" }, > + { 1<<23, "MP" }, > + { 1<<24, "ROP" }, > + {} > +};hex bitfields please :)> + > +static const char *const nv50_pgraph_vstatus_0[] = { > + "VFETCH", "CCACHE", "UNK4", "UNK5", "GSCHED", "STRMOUT", "UNK14XX", NULL > +}; > + > +static const char *const nv50_pgraph_vstatus_1[] = { > + "TPRAST", "TPROP", "TEXTURE", "TPVP", "MP", NULL > +}; > + > +static const char *const nv50_pgraph_vstatus_2[] = { > + "UNK24XX", "CSCHED", "UNK1CXX", "CLIPID", "ZCULL", "ENG2D", "UNK34XX", > + "ROP", NULL > +}; > + > +static void nouveau_pgraph_vstatus_print(const char *const units[], u32 status) > +{ > + int i; > + u32 tmp = status; > + for (i = 0; units[i] && tmp; i++) { > + if ((tmp & 7) == 1) > + pr_cont("%s ", units[i]); > + tmp >>= 3; > + } > + if (tmp) > + pr_cont("invalid: %x ", tmp); > + pr_cont("(0x%08x)\n", status); > +} > + > static int > nv84_graph_tlb_flush(struct nouveau_engine *engine) > { > @@ -219,10 +275,24 @@ nv84_graph_tlb_flush(struct nouveau_engine *engine) > !(timeout = ptimer->read(ptimer) - start > 2000000000)); > > if (timeout) { > - nv_error(priv, "PGRAPH TLB flush idle timeout fail: " > - "0x%08x 0x%08x 0x%08x 0x%08x\n", > - nv_rd32(priv, 0x400700), nv_rd32(priv, 0x400380), > - nv_rd32(priv, 0x400384), nv_rd32(priv, 0x400388)); > + nv_error(priv, "PGRAPH TLB flush idle timeout fail\n"); > + > + nv_error(priv, "PGRAPH_STATUS: "); > + tmp = nv_rd32(priv, 0x400700); > + nouveau_bitfield_print(nv50_pgraph_status, tmp); > + pr_cont(" (0x%08x)\n", tmp); > + > + nv_error(priv, "PGRAPH_VSTATUS_0: "); > + nouveau_pgraph_vstatus_print(nv50_pgraph_vstatus_0, > + nv_rd32(priv, 0x400380)); > + > + nv_error(priv, "PGRAPH_VSTATUS_1: "); > + nouveau_pgraph_vstatus_print(nv50_pgraph_vstatus_1, > + nv_rd32(priv, 0x400384)); > + > + nv_error(priv, "PGRAPH_VSTATUS_2: "); > + nouveau_pgraph_vstatus_print(nv50_pgraph_vstatus_2, > + nv_rd32(priv, 0x400388)); > } > > nv50_vm_flush_engine(&engine->base, 0x00); > -- > 1.7.8.6 > > _______________________________________________ > Nouveau mailing list > Nouveau at lists.freedesktop.org > http://lists.freedesktop.org/mailman/listinfo/nouveau
