Hello Daniel and other maintainers, While I'm working on drm memory allocator with myself, I've encountered render ring hang. And I am noticed that I can diagnose the command streamer's status with the following registers: INSTPS: 0x2070 CSCMDOP: 0x220c CSCMDVLD: 0x2210 INSTDONE_1: 206C I can see the general description of such registers in the following PDF. http://www.x.org/docs/intel/VOL_1_graphics_core.pdf But, sadly, this document does not provide a field description for implementation specific registers. I appreciate if you point me to such information in Haswell architecture? Best regards, JY _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
