Hey Everyone,
I started a small project called gputool to help me debug issues
on AMD platforms. I think it may be useful to other driver devs,
so I've made it available on github:
https://github.com/lostgoat/gputool
Mainly I wanted something that could read and decode registers,
so that is what is currently supported.
Example operation:
gputool> read CB_HW_CONTROL
CB_HW_CONTROL: 0x7208
FORCE_NEEDS_DST: 0x0
DISABLE_BLEND_OPT_WHEN_DISABLED_SRCALPHA_IS_USED: 0x0
DISABLE_BLEND_OPT_DISCARD_PIXEL: 0x0
DISABLE_BLEND_OPT_DONT_RD_DST: 0x0
PRIORITIZE_FC_EVICT_OVER_FOP_RD_ON_BANK_CONFLICT: 0x0
DISABLE_FULL_WRITE_MASK: 0x0
DISABLE_BLEND_OPT_RESULT_EQ_DEST: 0x0
DISABLE_INTNORM_LE11BPC_CLAMPING: 0x0
DISABLE_PIXEL_IN_QUAD_FIX_FOR_LINEAR_SURFACE: 0x0
ALLOW_MRT_WITH_DUAL_SOURCE: 0x0
DISABLE_CC_IB_SERIALIZER_STATE_OPT: 0x0
PRIORITIZE_FC_WR_OVER_FC_RD_ON_CMASK_CONFLICT: 0x0
FORCE_ALWAYS_TOGGLE: 0x0
FC_CACHE_EVICT_POINT: 0x8
CC_CACHE_EVICT_POINT: 0x7
DISABLE_RESOLVE_OPT_FOR_SINGLE_FRAG: 0x0
DISABLE_BLEND_OPT_BYPASS: 0x0
CM_CACHE_EVICT_POINT: 0x8
gputool> read PA_SC_RASTER_CONFIG
PA_SC_RASTER_CONFIG: 0x16000012
RB_XSEL: 0x0
SC_YSEL: 0x0
SC_MAP: 0x0
SC_XSEL: 0x0
SE_YSEL: 0x1
SE_XSEL: 0x1
PKR_YSEL: 0x0
RB_YSEL: 0x0
PKR_XSEL: 0x0
RB_XSEL2: 0x1
PKR_XSEL2: 0x0
SE_MAP: 0x2
RB_MAP_PKR0: 0x2
RB_MAP_PKR1: 0x0
PKR_MAP: 0x0
One of the other things I'm considering adding is register write
support, and also dumping textures from vram for inspection.
Regards,
Andres
