--- Comment #1 from Alexandre Demers alexandre.f.demers@gmail.com --- I added a line to output the value of "num_pipes" when it can't be matched to the defined values in the switch: fprintf(stderr, "Driver was unable to determine num_pipes (value = %i)\n", num_pipes);
I ended up outputting "Driver was unable to determine num_pipes (value = 12)", which is not coverded in the switch... Expected?
In commit 294ec530, r600_get_gb_tiling_config() was removed. num_pipes was defined there and a comment was telling: "/* Convert Sea Islands register values GB_ADDR_CFG and MC_ADDR_CFG * into GB_TILING_CONFIG register which is only present on R600-R700. */"
I'm using and R9 290X, which is a Sea Islands, covered by this comment.
