> Subject: [PATCH v2 3/3] drm/amdgpu/jpeg: support for sriov cpx mode
>
> In SRIOV CPX mode, each VF has 4 jpeg engines. The even- numbered VFs point
> to JPEG0 block of the AID and the odd- numbered VFs point to the JPEG1 block.
>
> Even-numbered VFs Odd numbered VFs
>
> VCN doorbell 0 VCN Decode ring VCN Decode ring
> VCN doorbell 1-3 Reserved Reserved
> VCN doorbell 4 JPEG0-0 ring
> VCN doorbell 5 JPEG0-1 ring
> VCN doorbell 6 JPEG0-2 ring
> VCN doorbell 7 JPEG0-3 ring
> VCN doorbell 8 JPEG1-0 ring
> VCN doorbell 9 JPEG1-1 ring
> VCN doorbell 10 JPEG1-2 ring
> VCN doorbell 11 JPEG1-3 ring
>
> Changes involve
> 1. sriov cpx mode - 4 rings
> 2. sriov cpx mode for odd numbered VFs - register correct src-ids (starting with
> JPEG4). Map src-id to correct instance in interrupt- handler.
>
> v2:
> 1. removed mmio access from interrupt handler. Use xcc_mask to detect cpx
> mode.
> 2. remove unneccessary sriov variables
