For those doing large Linux kernel builds such as with the "allyesconfig" build option for including as many of the available drivers as possible into the assembled Linux kernel image, objtool improvements ready to go with Linux 6.3 should cut down on the RAM usage and also speed-up the kernel build time. These improvements were motivated by Linux kernel developers beginning to run out of memory when trying to carry out the "allyesconfig" kernel builds on desktops with 32GB of RAM...

A few months back the generic xf86-video-modesetting X.Org driver added TearFree page-flipping support. The option eliminates screen tearing without the use of a compositor and was seen as a win by many for this generic DDX driver that works atop the modern DRM/KMS kernel drivers. But a rather annoying issue was discovered that could lead to audio/video synchronization problems was uncovered and is now fixed in the latest driver code...
