Improved OpenCL Support For Blender's Cycles Renderer Compared to the existing Radeon DRM driver, the new AMDGPU code is needed for AMD's new unified Linux driver strategy whereby the new Catalyst driver will be isolated to being a user-space binary blob with both the full open-source driver and the Catalyst driver using this common AMDGPU kernel driver. This patch series also lands the Userptr support for the open-source AMD graphics drivers on the user-space side.ĪMD Releases New "AMDGPU" Linux Kernel Driver & Mesa SupportĪt long last the source code to the new AMDGPU driver has been released! This is the new driver needed to support the Radeon R9 285 graphics card along with future GPUs/APUs like Carrizo. Support for the GL_AMD_pinned_memory OpenGL extension has landed within Mesa and is implemented for the R600g and RadeonSI Gallium3D drivers. The latest OpenGL 4+ activity in Mesa this week is a Saturday commit landing another OpenGL 4.5 extension for AMD's RadeonSI Gallium3D driver for GCN graphics processors. RadeonSI Gets OpenGL 4.5 Derivative Control Support However, they canceled twice on me last week for the call and thus waiting until 2016 to find out more.Īnyhow, the ten most popular AMD/Radeon stories on Phoronix in 2015 were: Last week we were finally scheduled to have a conference call to further discuss Linux/GPUOpen at their request. Sadly there, I'm still waiting to find out more Linux details about their plans for 2016. Most recently, the Radeon Technologies Group announced the GPUOpen initiative.
Much of the interest by Phoronix readers has been in the open-source driver stack while waiting for Catalyst / Radeon Software to switch over to the new driver model of being limited to a user-space blob that's riding off the AMDGPU kernel driver. On a related note to yesterday's The Mesmerizing Mesa Milestones Of 2015, this article is looking at the most popular AMD/Radeon content on Phoronix for this calendar year.
AMD's open-source driver stack now supports OpenGL 4.1 for GCN GPUs and select pre-GCN graphics cards plus the other driver stack also matured in other ways this year. AMD's open-source graphics driver stack continued maturing in 2015 while Catalyst (now known as Radeon Software) releases were rare.
