| tfiga | hverkuil: I'll try to take a look a bit later | [08:20] |
| hverkuil | ezequielg: the rkvdec driver only needs a follow-up patch adding a MAINTAINERS entry, and then I can post a PR for it. Can you do that today? (PS: don't forget to also refer to the binding file in the MAINTAINERS entry, it's easy to forget about that one) | [08:27] |

| ezequielg: see my follow-up mails, a v6 is needed after all. | [09:22] | |
| ezequielg | hverkuil: ok. I will try today. | [09:28] |

| dafna2 | hverkuil: hi, the rkisp1 driver fails in the compliance tests, in the case of using userptr when streaming
the error is because the vb2_dma_contig_memops expect the buffers allocated by the userspace to be alligned I wonder if it should be fixed in v4l-utils, or either just drop the support for userptr? | [18:09] |
| hverkuil | Drop support for userptr. userptr support makes no sense for drivers based on vb2_dma_contig. Support for userptr for dma_contig exists primarily for old drivers that abused userptr giving it pointers to known contiguous data (usually from a special memory pool).
I'm not even sure if those drivers are still in use, I thought it was mostly soc-camera that did this. Tomorrow I'll check to see who still uses this and if support for this can be killed. | [18:12] |
| dafna2 | ok, and if it can you will send a patch removing support from all drivers with contig_dma?
in that case I don't have to write a patch just for rkisp1 | [18:20] |
| hverkuil | That's putting the cart before the horse :-)
It's a simple patch for rkisp1: just remove VB2_USERPTR for any dma_config queue. | [18:26] |
| dafna2 | :-) ok | [18:37] |
