Mesa DRM Library Update Fixes Critical RadeonSI Bug

The Mesa DRM library (libdrm) was updated to version 2.4.50 today in order to address a critical bug affecting the RadeonSI driver for Radeon HD 7000 series GPUs and newer.

The critical bug that was patched from libdrm 2.4.49 would lead to crashes when running some OpenGL applications or even Google Chrome from the open-source AMD RadeonSI driver. The bug documenting the issue is on the FreeDesktop.org BugZilla.

There was a fix committed for this issue, "radeon: Update unaligned offset for 2D->1D tiling transition on SI." The only other change squeezing into libdrm 2.4.50 is an Intel change by Keith Packard for tracking known DRI PRIME buffers for re-use that were previously already passed to the game/application.

The libdrm 2.4.50 release announcement can be found on dri-devel.
