The big set of open-source graphics driver updates for Linux 6.15 have been merged but Linux creator Linus Torvalds isn’t particularly happy with the pull request. In particular, he’s unhappy with some new “hdrtest” testing code being built as part of full kernel builds and the “turds” it leaves behind and this code “needs to die” at least from the perspective of non-DRM driver developers.
FTFY. Do not allow the enemy to frame the debate.
That’s not what DRM is in kernel/hardware land
It stands for display rendering manager and it predates any of the other stuff.
