How to use vce1 in Radeon Pro WX5100

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all

     I found two vce block under /sys/kernel/debug/dri/1/amdgpu_ring_vce0 & amdgpu_ring_vce1.

when I use ffmpeg to do H.264 encoding , I use “umr ?top”  and press “c” to show the VCE loading,  and

I found that only vce0 had loading , and vce1 always be 0%, like this:

VCE Bits:

VCE0 =>     100%   |            VCE1 =>     0 %   |

  So I think vce1 block has never been used, and how to select vce1 to do encode ?

My environment:

Radeon Pro WX5100

Mesa18.0.5

Linux kernel 4.19

 

Please help!
