AMDGPU Semaphores Support Getting Squared Away

Written by Michael Larabel in Radeon on 19 January 2016 at 10:30 PM EST. 3 Comments

The user-space side of semaphore support is getting taken care of for the new AMDGPU driver.

Landing today in Mesa DRM (libdrm) is the semaphore support for AMDGPU with this library that sits between the AMDGPU kernel DRM and the RadeonSI Gallium3D driver.

Details on the semaphore implementation for AMDGPU can be found via this Git commit. At last check, the AMDGPU DRM driver wasn't enabling semaphores support by default. Details on semaphore can be found from this forum thread and is not to be confused with the other semaphores: this article.
