Hi, We are trying ATI HD 7470 card on arm64 platform D05 with kernel 4.1.40. But it failed with kernel log: radeon 0005:01:00: ring 0 stalled for more than 10000msec radeon 0005:01:00: GPU lockup (current fence id 0x0000000000000001 last fence id 0x0000000000000002 on ring0) radeon 0005:01:00: ring 0 stalled for more than 10500msec radeon 0005:01:00: GPU lockup (current fence id 0x0000000000000001 last fence id 0x0000000000000002 on ring0) radeon 0005:01:00: ring 0 stalled for more than 11000msec radeon 0005:01:00: GPU lockup (current fence id 0x0000000000000001 last fence id 0x0000000000000002 on ring0) radeon 0005:01:00: ring 0 stalled for more than 11500msec radeon 0005:01:00: GPU lockup (current fence id 0x0000000000000001 last fence id 0x0000000000000002 on ring0) ... Any clue? Any required setting on BIOS IO mem bar video ram? It seems that our PCIE controller doesn't support cacheable feature for IO mem bar video ram.
