I think something important which distinguishes a prolific FOSS contributor from someone who isn't, in the context of marketable skills, is the ability to quickly dive into a new codebase and familiarize yourself with it enough to be productive. Many of the FOSS developers I know can be writing useful patches within hours or even tens of minutes of their first exposure to a codebase.

If someone's wondering what's the right kernel tree to use when writing amdgpu patches:

git remote add agd5f git://people.freedesktop.org/~agd5f/linux
git checkout agd5f/drm-next

I always forget it when I stop working on amdgpu for a while.

Started a wiki page about VRR setups and issues w/ Sway:

github.com/swaywm/sway/wiki/VR

If you happen to have a VRR screen, feel free to add an entry!

So, yeah, *&%*($ to silently ignoring errors, XCB.

It turns out sending a closed FD via XCB doesn't fail. The other side (X.Org server) just receives a random FD number, which I think by chance referred to an unrelated FD which was opened.

But why was I sending a closed FD via XCB in the first place? It turns out sending a FD via XCB also closes it. So it worked fine the first time, and caused the bug the second time.

This morning I spent a few hours tracking down a bug in wlroots' X11 backend. Importing a DMA-BUF via the X11 DRI3 extension failed, and I couldn't understand why.

Went from X.Org server core to Xwayland to GBM to Gallium to radeonsi to libdrm to the kernel. The FD seemed valid, since stat() didn't return an error, but drmPrimeFDToHandle failed.

Initial renderer v6 work merged in wlroots 🎉

Can't wait to be able to take advantage of that for libliftoff, explicit sync and all of the cool upcoming features!
