Doing so would require wiring up various new DRM fourcss and support in #mesa drivers - i.e. quite a bit of work - but initial, totally unoptimized results are very promising and the approach leaves a lot of room for improvements and extensions, e.g. new dmabuf APIs for better upload performance to dedicated GPUs, optionally using heaps like CMA etc.

That's why I'd love to hear opinions from people in the field if they generally consider this a good idea.

For video/multimedia/graphics on #linux people: I made a PoC for gstreamer using udmabuf to allocate YCbCr buffers for sw-decoded video that can be imported by GPU drivers.
The basic idea is to allow to reuse the highly optimized hw-decoding dmabuf import paths in drivers/toolkits/apps for sw-decoding, so they can cover arbitrary new codecs and less usual formats - e.g. AV1 and H266 on hardware that doesn't have HW support or 422/444 subsampling.

It's somewhat annoying to have to go into the settings every morning to turn off the night color from the previous day when using KDE with Wayland. I read that there are supposed to be some issues with night color mode on Nvidia cards, but I have an AMD Radeon.

Been running Gnome 48 on Debian Trixie for the last day or so. I like it.

I'm also making a concerted effort to give Web (Epiphany) a solid try. In the last number of hours have not encountered any issues when using it to access Mastodon or Kijiji Autos. Just regular browsing normal sites seems to work fine.

I haven't accessed any terrible banking sites or anything like that yet. I half expect to have to keep Floorp around for that bull-roar.

Weirdly, with Web, the scrolling and rendering on my 'big' workstation (11700k, RTX4070) is kind of rough compared to my laptop which seems really smooth and snappy (10750H, GTX1650). Both are on Wayland. Both are UHD screen (lappy is UHD+ 16:10 actually).

For those encountering random video playback application crash heisenbugs on the open source #AMDgpu #Mesa drivers on #Linux (thankfully, with #Wayland this no longer crashes the entire system), with the suspicious "CS has been rejected" error, here is the bug I reported upstream: gitlab.freedesktop.org/mesa/me

The theory is that the DRM's implementation of AMD's Unified Video Decoder does not properly keep track of #Flatpak process IDs. A patch is underway.

#FOSDEM is over.
How many of you have seen Bad Apple running on an e-paper screen, smoothly?
Because I have, at a private presentation in one of the sitting areas, and, friends, it blew my socks off.
Let me tell you, it's funny to see something cast a shadow on a computer screen.

Apparently the driver is running a custom FPGA and plenty of it is open source.

Good luck @modos . I want to get one now. modos.tech/blog
