Sent out today were all of the DRM/accel driver fixes for the week, ahead of the Linux 7.0-rc2 kernel release due out on Sunday.
Standing out with this week’s Direct Rendering Manager subsystem updates are many fixes to the AMDXDNA accelerator driver for AMD Ryzen AI NPUs. Typically it’s the AMDGPU driver or Intel Xe leading the race each week for the most fixes, but this time around AMDXDNA has more than usual.
There are many different AMDXDNA fixes queued up including addressing a system suspend failure with this driver, buffer overflow fix, input sanitization fix, deadlock fix, a NULL pointer dereference bug, an out-of-bounds access fix, and also a firmware loading fix. Yes, many of these bugs now fixes stem from the C programming language use for this driver while many passionate individuals will surely argue this is another case of a kernel driver that should be written in Rust for its memory safety benefits.
Beyond those different AMDXDNA fixes, there are also some AMDGPU fixes for the user queue “UserQ” support, DC display fix, VCN 5 fix, and other fixes. To the Intel Xe, Nouveau, and other drivers are just a few small fixes with nothing really standing out there.
