WhoWhatWhen
ezequielgmripard: ah of course
mchehab: "[GIT PULL for v4.20-rc1] new experimental media request API" contains a patch from me, but it shouldn't be there.
"media: dt-bindings: Document the Rockchip VPU bindings" should not be part of that pull.
[14:05]
mchehabezequielg: why not? it shouldn't go upstream? [14:06]
ezequielgno
the rockchip vpu is the JPEG encoder that we talked about
you objected the JPEG_RAW format, and after some discussion I agreed with you.
so I know have to re-do the driver
the bindings are probably OK, but I wouldn't want to confuse people by submitting a bindings without a driver.
[14:07]
mchehabok, pls send me a revert patch. I'll add it to my tree and send later upstream [14:08]

mchehab(I'll very likely send one last PR during the merge window - I'll place it there) [14:09]

jhautboispH5, I sent a mail on the ML as I can't get through an issue with mipi-csi2 with i.MX6... I don't think this is related to continuous clock, and am stuck. Thanks for the doc from yesterday, wad very helpful ! [16:43]
pH5jhautbois: ok, I'll have a look later. [16:44]
jhautboisthanks [16:47]

ezequielghverkuil: after our talk with pinchartl, do you think we can merge [PATCH v5 0/2] media: usb: pwc: Don't use coherent DMA buffers for ISO transfer ? [21:14]
...... (idle for 28mn)
pinchartlezequielg: I had a quick look at the patch. as explained before I think we need to fix a few things in the dma-mapping API in order to solve the problem cleanly, but given the performance improvement, I see no reason to block the patch
I'd love it if someone could work on the non-coherent allocation API though
[21:42]
........................ (idle for 1h55mn)
ezequielgpinchartl: well, I submitted a naive set for the DMA API
I have to say, I am also concerned about moving away from a CMA-backed path for the allocation
and that's why I haven't done anything on stk1160, although a similar patch would improve performance on some popular platforms
I just haven't made up my mind
note that my objection is not about the patch itself, but about lack of clear directions.
I know everyone hates parameters, but I think we could have just lived with some new parameter, and a comment saying it should go away, once X, Y, Z features get merged
and merge the patch ages ago
