--- Comment #84 from Julien Isorce <julien.iso...@gmail.com> --- I think I now why the workaround is no applied, it is because it is only for NVE4, 6 and 7. And my GT 750M seems to be threatened as "NVC0 (GF100) GeForce GTX (465, 470, 480, 480M) Quadro 4000, 5000[M] (??), 6000". See http://nouveau.freedesktop.org/wiki/CodeNames/. Indeed it fails in gf100.c:1478/gf100_gr_init_ctxctl (i.e. GF100) instead of going to gk104.c (i.e. NVE4 GK104, or NVE7 GK107) where the War00C800 is handled. Or maybe this is an expected behavior since I am not trying to use this graphic card (GT 750M) for X11 but only for HW decoding. (the other graphic card, intel is set to be used by the X11). When running LIBVA_DRIVER_NAME=gallium vainfo --display drm It hits "case 0xe0: obj_class = NVE4_P2MF_CLASS;" in nvc0_screen_create #0 abi16_engobj (obj=0x613d20) at abi16.c:109 #1 0x00007ffff4163165 in nouveau_object_new (parent=parent@entry=0x613750, handle=handle@entry=3203347007, oclass=41024, data=data@entry=0x0, length=8, length@entry=0, pobj=pobj@entry=0x613728) at nouveau.c:295 #2 0x00007ffff50ab4c9 in nvc0_screen_create (dev=0x6131e0) at nvc0/nvc0_screen.c:722 #3 0x00007ffff4fb9d59 in nouveau_drm_screen_create (fd=fd@entry=3) at nouveau_drm_winsys.c:119 #4 0x00007ffff4e59944 in pipe_nouveau_create_screen (fd=3) at ../../../../src/gallium/auxiliary/target-helpers/inline_drm_helper.h:171 #5 dd_create_screen (fd=fd@entry=3) at ../../../../src/gallium/auxiliary/target-helpers/inline_drm_helper.h:392 #6 0x00007ffff4e5a71e in __vaDriverInit_0_38 (ctx=0x604030) at context.c:152 #7 0x00007ffff7bc10e8 in va_openDriver (dpy=dpy@entry=0x604220, driver_name=<optimised out>) at va.c:296 #8 0x00007ffff7bc1fab in vaInitialize (dpy=dpy@entry=0x604220, major_version=major_version@entry=0x7fffffffb820, minor_version=minor_version@entry=0x7fffffffb824) at va.c:559 #9 0x00000000004015d0 in main (argc=1, argv=0x7fffffffb978) at vainfo.c:116 (gdb) n 118 dev = nouveau_object_find(obj, NOUVEAU_DEVICE_CLASS); (gdb) n 109 { (gdb) n 111 .channel = obj->parent->handle, (gdb) n 110 struct drm_nouveau_grobj_alloc req = { (gdb) n 118 dev = nouveau_object_find(obj, NOUVEAU_DEVICE_CLASS); (gdb) n 119 ret = drmCommandWrite(dev->fd, DRM_NOUVEAU_GROBJ_ALLOC, (gdb) n 121 if (ret) (gdb) n 126 } (gdb) n nouveau_object_new (parent=parent@entry=0x613750, handle=handle@entry=3203347007, oclass=41024, data=data@entry=0x0, length=<optimised out>, length@entry=0, pobj=pobj@entry=0x613728) at nouveau.c:296 296 break; (gdb) n 302 if (ret) { (gdb) n 303 free(obj); (gdb) n 309 } (gdb) n 304 return ret; (gdb) n 309 } (gdb) n nvc0_screen_create (dev=0x6131e0) at nvc0/nvc0_screen.c:724 724 if (ret) (gdb) n 725 FAIL_SCREEN_INIT("Error allocating PGRAPH context for M2MF: %d\n", ret); (gdb) ret is -16 Any idea ?
