Stemming from an ongoing Mesa GBM discussion over introducing new gbm_bo_create_with_modifiers2 / gbm_surface_create_with_modifiers2 functions since the original "gbm_*_create_with_modifiers" functions lack support for passing usage flags, NVIDIA confirmed that the Sway Wayland compositor is working fine with their forthcoming driver supporting GBM...

While Samsung has explicitly stated before that queued TRIM works for Samsung 860 SSDs on Linux and thus leading to only older Samsung 840/850 drives being blocked from queued TRIM usage, that turns out to be inaccurate and now more quirks are added for the Samsung 860 and 870 series SSDs on Linux...

With the in-development Linux 5.15 kernel there is a new option for further protecting the kernel around side channel attacks and information leakage. Enabling the option will ensure that any caller-used register contents are zeroed prior to returning from a function. While the reported performance cost is said to be small, I decided to run some benchmarks when toggling this new Kconfig hardening option.
