Subject: [PATCH] media/rpivid: Allow use of iommu in rpivid
|
|
|
|
In order to use iommu on hevc set dma mask_and_coherent in probe.
|
|
I am assured dma_set_mask_and_coherent is benign on Pi4 (which has
|
|
no iommu) and it seems to be so in practice.
|
|
Also adds a bit of debug to make internal buffer allocation failure
|
|
easier to spot in future
