Mesa Picks Up Support For Some OpenGL 4.5 Extensions
Mesa developers continue making headway in supporting more of the Khronos OpenGL 4.x specifications... OpenGL 4.0~4.2 is hopefully not too far out, at least for the Intel Linux driver.
Besides the Mesa improvements covered on Phoronix today, yesterday, and other preceding days, some of the latest Mesa work that hit over the night includes:
- ARB_derivative_control of OpenGL 4.5 has been implemented in R600g for Evergreen/Cayman (Radeon HD 5000 series and newer) and the Intel (i965) Linux driver. Support was already present for Nouveau (NV50/NVC0) since yesterday while the RadeonSI support is still outstanding.
- ARB_gpu_shader5 is now supported by the Intel driver for Ivy Bridge hardware and newer. This is required for OpenGL 4.0 support and up to now only the Nouveau NVC0 driver supported this extension.
- ARB_texture_barrier is now supported by all the major Mesa/Gallium3D drivers as it's identical to NV_texture_barrier. ARB_texture_barrier was approved for OpenGL 4.5.
