00:27 <lrusak> anyone know the state of the imx6 drm/kms driver? Is it useable?

00:28 <lrusak> would be interesting if my drm/kms work in kodi will work on the imx6 platform

00:28 <lrusak> seems that the gpu accel is separate so that might work still

06:25 <tomeu> lrusak: I would say that on recent kernels, it's very usable

16:22 <lrusak> tomeu, how feature complete is the mainline kernel in terms of imx6 stuff? what isn't working yet?

16:22 <lrusak> I have yet to get an imx6 device so I'm not able to test myself

16:26 <vpeter> lrusak: Far to be used for kodi :(

16:28 <vpeter> lrusak: and you have jnettlet on slack - ask him.

16:31 <vpeter> And I think he has some extra patches for mainline kernel for sr devices.

16:35 <paulk-collins> overall it's quite good though

16:35 <paulk-collins> coda is supported, etnaviv is getting in shape

16:35 <paulk-collins> having a scaling accelerator would be nice

16:36 <dv_> you mean 2D scaling?

16:43 <paulk-collins> yeah

16:43 <paulk-collins> especially for video scaling

16:44 <paulk-collins> that's still the weak point when decoding videos with a mainline setup

16:44 <dv_> yep. so far, typically the GPU's 3D core is used for that (through opengl)

16:45 <dv_> however, the 3D core of vivante GPUs use much more power than the 2D core

16:45 <dv_> I have been toying around with an idea to create a userspace 2D API for accessing the 2D cores of the imx6, but there is no established hardware agnostic 2D API that can be used (so, no 2D counterpart to opengl)

16:47 <paulk-collins> isn't the DDX using the 2D cores though?

16:47 <paulk-collins> and implementing some xv bits?

16:47 <dv_> this is X11 though

16:47 <paulk-collins> yeah right

16:47 <dv_> and it doesnt do offscreen scaling

16:47 <paulk-collins> (and it's not really a big help in practice)

16:47 <dv_> so, nothing like my imxg2dvideotransform elements for example

16:48 <paulk-collins> what I was referring to is a block inside the IPU though

16:48 <dv_> the next best thing would probably be directfb, but that API is dead, and quite bloatd

16:48 <dv_> *bloated

16:48 <paulk-collins> well there's v4l2 mem2mem for scaling too, right?

16:49 <paulk-collins> that's how it's done on exynos: https://blogs.s-osg.org/video-decoding-exynos-multi-format-codec-gstreamer/

16:49 <paulk-collins> unless I'm mistaken

16:49 <paulk-collins> nah seems to be decoding only

16:49 <paulk-collins> my bad

16:50 <paulk-collins> ah that's it: v4l2video0convert
