Hello Xiangliang Yu,
The patch ab71ac56f6d8: "drm/amdgpu/virt: implement VI virt operation
interfaces" from Jan 12, 2017, leads to the following static checker
warning:
drivers/gpu/drm/amd/amdgpu/mxgpu_vi.c:310
xgpu_vi_init_golden_registers()
warn: string literals are always true.
drivers/gpu/drm/amd/amdgpu/mxgpu_vi.c
294 break;
295 case CHIP_TONGA:
296 amdgpu_program_register_sequence(adev,
297
xgpu_tonga_mgcg_cgcg_init,
298 (const u32)ARRAY_SIZE(
299
xgpu_tonga_mgcg_cgcg_init));
300 amdgpu_program_register_sequence(adev,
301
xgpu_tonga_golden_settings_a11,
302 (const u32)ARRAY_SIZE(
303
xgpu_tonga_golden_settings_a11));
304 amdgpu_program_register_sequence(adev,
305
xgpu_tonga_golden_common_all,
306 (const u32)ARRAY_SIZE(
307
xgpu_tonga_golden_common_all));
308 break;
309 default:
310 BUG_ON("Doesn't support chip type.\n");
BUG_ON() takes a condition argument, not a format string.
311 break;
312 }
313 }
regards,
dan carpenter
