drm/amdgpu: Fix static assertion failure issue
Since the PAGE_SIZE is 8KB on sparc64, the size of structure amdsriov_ras_telemetry will exceed 64KB, so use absolute value to fix the buffer size. Fixes the issue: drivers/gpu/drm/amd/amdgpu/amdgv_sriovmsg.h:522:2: error: static assertion failed due to requirement 'sizeof(struct amdsriov_ras_telemetry) <= 64 << 10': amdsriov_ras_telemetry must be 64 KB | sizeof(struct amdsriov_ras_telemetry) <= AMD_SRIOV_MSG_RAS_TELEMETRY_SIZE_KB_V1 << 10, drivers/gpu/drm/amd/amdgpu/amdgv_sriovmsg.h:522:40: note: expression evaluates to '115616 <= 65536' | sizeof(struct amdsriov_ras_telemetry) <= AMD_SRIOV_MSG_RAS_TELEMETRY_SIZE_KB_V1 << 10, Fixes: cb48a6b2b61d ("drm/amd/ras: use dedicated memory as vf ras command buffer") Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202602261700.rVOLIw4l-lkp@intel.com/ Signed-off-by: YiPeng Chai <YiPeng.Chai@amd.com> Reviewed-by: Tao Zhou <tao.zhou1@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
