Hi Jaeyong, Intel releases its GPU PRM on 01.org. As for HSW, the manuals can be found at :
https://01.org/linuxgraphics/documentation/2013-intel-core-processor-family
Thanks for the answer. I searched in the "HSW - Volume 2c: Command Reference: Registers" one and I can not see INSTPS nor 2070. I think this PRM is not including all registers.
Unfortunately I didn't find it either.
Actually we use an internal version of GEN manuals, which is more detailed. By occasion there are things missing in the published ones. Sorry for that..
While I'm having some fun on drm memory allocator in kvmGT, 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?
