Mesa developer Samuel Pitoiset has been hired by Valve to work on RADV support in preparation for the new AMD GFX11 GPUs, also known as RDNA 3, before their launch. RADV is the open-source Radeon Vulkan driver integrated into Mesa 22.2 and Linux 5.19. RADV is not an official AMD driver but continues to be more widely used than the company's own AMDVLK driver.

Since the company does not officially support the open-source RADV driver, third parties must integrate and help support its effort to find a home in the open-source sections. Pitoiset's inclusions into the RADV GFX11 'AMD RDNA 3' driver support focus "on learning design changes" regarding the new generation of graphics cards.
