<smaeul> apritzel: You could send the vendor/board bindings and DTs without USB nodes, and add those in the USB series, so none of the other series are holding up the new boards

<wens> anyone know what the "VE_R" port in the H6 IOMMU is for? I seem to have stepped on an IOMMU error on port 1
<wens> also, the Hantro block is missing an IOMMU reference. I will send a patch for that.
<smaeul> is VE_R not the hantro block?
Daanct12 has quit [Quit: Quitting]
<wens> no, hantro is the "VP9" block, id = 5
<wens> there's VE: port = 3, and VE_R: port = 1

<wens> sun50i-iommu 30f0000.iommu: Page fault for 0x00000000fcbd34c0 (master 1, dir rd)
<wens> cedrus 1c0e000.video-codec: frame processing timed out!
<wens> this is what I'm getting
<wens> difference being that the Chrome VDA test is using MEMORY_TYPE_DMABUF on the capture side

<wens> or maybe the Chrome stack is doing something else funny :/

<jernej> wens, smaeul: Cedrus on H6 actually needs both iommu channels
<jernej> that become obvious during HEVC and IOMMU development
<jernej> I got page faults from both channels
<jernej> it seems that MPEG2 and VP8 use only one channel and H264 and HEVC both channels
<jernej> wens: iommu was useless for Cedrus until I fixed all issues with it
<jernej> so you should pick all patches from linux-next, if you don't have it
<jernej> wens: here is my branch, with all the posted iommu and cedrus fixes: https://github.com/jernejsk/linux-1/commits/hevc-10
<jernej> most of them will be merged for 6.2

<wens> I've picked all the iommu and cedrus patches
<wens> so I guess I need the dts patch to add the second channel
dikiy has joined #linux-sunxi
<jernej> wens: not really, since it currently doesn't matter
<jernej> if iommu driver is loaded, all iommu channels are enabled
<jernej> callback to enable iommu channel based on DT values is not implemented (yet)
<jernej> wens: but DT fixes, like in hantro case, are appreciated :)

<smaeul> it will matter as soon as I send v2 of the D1 IOMMU series, since D1 enables bypass by default, and I was told to disable it per channel
<smaeul> so presumably we would enable bypass by default
