In complementing this week's Linux review of the AMD Radeon R9 285 and follow-up articles with some extra GPU scaling tests and Catalyst AI Linux benchmarks, here's some more OpenCL R9 285 "Tonga" performance numbers under Ubuntu compared to what was shared in the original Linux review.
AMD's patches to add support to compiling to native object code for the "Clover" OpenCL state tracker in Mesa's Gallium3D and for the Radeon Gallium3D driver to take advantage of this functionality, has landed.
Along with today's R9 285 GPU scaling tests from Ubuntu, other Linux graphics tests I ran from the AMD Radeon R9 285 GCN 1.2 graphics card is a check whether to see Catalyst AI is doing much on Linux.
For those wondering about the maximum resolution they can run given OpenGL workloads at with the AMD Radeon R9 285 "Tonga", a new ~$250 USD graphics card, here's some Linux GPU scaling benchmarks with the Catalyst driver.
Last week we wrote about AMD's new unified open-source / Catalyst Linux graphics driver strategy and now today we know a bit more information... The AMDGPU kernel driver isn't starting off with the Radeon Rx 300 series but rather the already out Radeon R9 285 "Tonga" graphics card will be the first GPU to use the new driver.
Given yesterday's big update about AMD's unified Linux driver approach and creating a new "AMDGPU" kernel driver, open-source driver developers independent of AMD who have worked on the current Radeon code are already proposing API improvements.
The Linux 3.18 kernel will bring support for reading the core temperature of AMD's forthcoming "Carrizo" APUs.
The AMD news keeps rolling today... The latest is word hitting the wire that Rory Read has stepped down from AMD.
If you go back more than seven years ago, lots of people took easy aim at the state of ATI/AMD's Linux graphics drivers. Back then, they didn't even have an open-source strategy... How times have changed.
Today to kick off XDC, AMD announced its rolling with its new Linux driver model that includes the development of a new kernel DRM driver.
On Monday I wrote about AMD adding native object code support to their Radeon Gallium3D drivers and Clover. Besides being a huge performance win for OpenCL kernel compile times, this work is also instrumental as part of AMD's open-source HSA Linux plans.
Tom Stellard announced his latest OpenCL-related improvements to the open-source Radeon Linux graphics driver.
AMD's Alex Deucher released a new version of the xf86-video-ati DDX driver for X.Org Servers on Wednesday night.
For those using the Gallium3D HUD, RadeonTOP, or other utilities, more data is being exposed with new patches for the Radeon DRM driver.
There's a lot of work going on right now to the AMD Catalyst Linux graphics driver. We've written about new features coming to an upcoming Catalyst Linux driver but silently being pushed into the latest round of release is a GLSL shader disk cache.
AMD has released the Catalyst 14.9 Linux graphics driver today with some modest changes but it's not the really big driver update we're waiting for.
Earlier this year I delivered the exclusive news how AMD was looking at a new Linux driver strategy for Catalyst that involved leveraging the open-source Radeon DRM kernel driver. The strategy at the time effectively meant just making Catalyst a user-space blob and riding off the open-source Radeon kernel driver to share more common code and hopefully lead to a better experience. It looks like this driver strategy is moving forward.
AMD is soliciting feedback on the Catalyst driver.
Yesterday I wrote about an upcoming Catalyst Linux driver offering VCE and HSA support while today are more details on this forthcoming update.
AMD's Alex Deucher sent in another Radeon drm-next patch series this week with some more last-minute tweaks for the Linux kernel's next merge window.
AMD's trying hard to make HSA of benefit to Linux users in 2014 and they're making lots of inroads. Helping AMD along the way with the Linux raising of Heterogeneous System Architecture is SUSE.
While AMD just released its first OpenCL 2.0 Linux driver, which is marked fglrx 14.41, the next driver that's currently in testing is fglrx 14.50... This should be more interesting.
A new AMD Catalyst Linux graphics driver has been released today that finally delivers OpenCL 2.0 to Catalyst.
Marek Olšák has published another big set of fixes/improvements to the open-source RadeonSI Gallium3D driver.
Another Radeon DRM driver update pull request has been submitted to drm-next for merging in the Linux 3.18 kernel.
Those dependent upon AMD's proprietary Linux graphics driver have a new Catalyst update to play with today.
Well known open-source Radeon driver developer Marek Olšák has landed a number of commits today inside mainline Mesa Git for improving the state of HyperZ for AMD hardware, a feature that remains disabled by default for the open-source Radeon Linux driver due to stability and artifact issues.
Yesterday I wrote about Ubuntu 14.10 not yet having X.Org Server 1.16 even though the first beta was issued this week and there's been a testing package repository for more than one month. This lack of X.Org Server 1.16 thus far is apparently due to AMD with not yet having a supportive Catalyst driver.
A German web-site is hosting a yet to be officially released Catalyst Linux driver.
With the DRM merge window for drm-next now closing earlier going forward than in past kernel releases, another Radeon DRM-Next pull request was already submitted for Linux 3.18.
