drm/amdgpu: Check for valid number of registers to read

2019-10-17T20:42:12+00:00

[ Upstream commit 73d8e6c7b841d9bf298c8928f228fb433676635c ] Do not try to allocate any amount of memory requested by the user. Instead limit it to 128 registers. Actually the longest series of consecutive allowed registers are 48, mmGB_TILE_MODE0-31 and mmGB_MACROTILE_MODE0-15 (0x2644-0x2673).

They are separate identification spaces.

drm/amdgpu: set COMPUTE_PGM_RSRC1 for SGPR/VGPR clearing shaders

2018-05-01T22:13:09+00:00

commit 75569c182e4f65cd8826a5853dc9cbca703cbd0e upstream. Otherwise, the SQ may skip some of the register writes, or shader waves may be allocated where we don't expect them, so that as a result we don't actually reset all of the register SRAMs. This can lead to spurious ECC errors later on if a shader uses an uninitialized register.
