For example, for 4 VF, every<br> VF's exclusive timeout time is set to 3s, then the worst case is<br> 9s. If the VF number is more than 4,then the worst case time will<br> be longer.<br> The 8s is the test data, with setting to 8s, it will pass the TDR<br> test for 1000 times.<br> <br> SWDEV-161490<br> <br> Change-Id: Ifc32d56ca7fde01b1f4fe2b0db6959b51909008a<br> Signed-off-by: Monk Liu <Monk.Liu@amd.com><br> Signed-off-by: Emily Deng <Emily.Deng@amd.com><br> ---<br> drivers/gpu/drm/amd/amdgpu/amdgpu_device.c | 2 +-<br> 1 file changed, 1 insertion(+), 1 deletion(-)<br> <br> diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c<br> index 1d933db..ef82ad1 100644<br> --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c<br> +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c<br> @@ -3124,7 +3124,7 @@ static int amdgpu_device_handle_vram_lost(struct amdgpu_device *adev)<br> long tmo;<br> <br> if (amdgpu_sriov_runtime(adev))<br> - tmo = msecs_to_jiffies(amdgpu_lockup_timeout);<br> + tmo = msecs_to_jiffies(8000);<br> else<br> tmo = msecs_to_jiffies(100);<br> <br> -- <br> 2.7.4<br> <br> _______________________________________________<br> amd-gfx mailing list<br> amd-gfx@lists.freedesktop.org<br> <a href="https://lists.freedesktop.org/mailman/listinfo/amd-gfx" id="LPlnk239167" class="OWAAutoLink" previewremoved="true">https://lists.freedesktop.org/mailman/listinfo/amd-gfx</a><br> </div> </span></font></div> </div> </div> </body> </html>
