Tom Stellard is looking to kick things off well in 2015 for the open-source AMD GPU LLVM back-end with some new patches to boost the performance.
This really shouldn't come as a huge surprise, but AMD won't support HSA on 32-bit Linux.
As said last week that a huge new Catalyst Linux driver release would be coming on Tuesday and sure enough it has arrived. Catalyst 14.12 is the biggest AMD proprietary Linux graphics driver update in quite some time.
Due out next week is a very significant update to AMD's Catalyst Linux graphics driver as they continue to work towards the unified AMD Linux driver strategy.
The AMDKFD driver, which has been under development in the public spotlight for the past few months as a necessary piece to having AMD HSA open-source support on Linux, will premiere with the Linux 3.19 kernel.
Just one week after the bulk of the Radeon DRM changes for Linux 3.19, another round of updates were submitted for DRM-Next.
Alex Deucher of AMD has put out new Radeon DPM patches that add SMC fan control support for SI/CI GPUs. These new patches should reduce the graphics card's fan noise on systems with a higher default fan profile speed.
While the new "AMDGPU" kernel driver won't be merged until at least Linux 3.20, it looks like the AMDKFD driver could be merged for the upcoming Linux 3.19 kernel.
Last week we reported on AMD's plans for a complete user-space open-source HSA stack. Today they have finally delivered!
As a follow up to yesterday's 16-way AMD GPU comparison with the latest open-source Linux graphics drivers, here's some numbers with the same graphics cards when adding in the Catalyst Linux graphics driver... The numbers may very well surprise you.
While AMD's new GPU kernel driver isn't coming for Linux 3.19, another pull request has been sent in for the current Radeon DRM driver and it offers up a few last minute enhancements.
It looks like the first point release to LLVM 3.5 will be out in December.
The R600g Gallium3D driver has new patches available -- along with a needed kernel patch -- for supporting OpenGL 4.0's GL_ARB_draw_indirect extension.
In the coming days AMD will be releasing AMD's HSA run-time library as open-source!
Tom Stellard has more improvements coming for AMD's GPU LLVM back-end that can yield performance improvements.
For those stuck running on the R300g driver, which supports the ATI Radeon X1000 (R500) series and older GPUs, you really should consider upgrading your graphics card and likely your system. But if you're set on using the R300g driver going into the foreseeable future, you might as well upgrade Mesa.
As a quick update to a Phoronix story from earlier this week, the HyperZ performance boosting feature has been re-enabled in Mesa Git for RadeonSI and R600g!
AMD reported their Q3'2014 results yesterday and they weren't good for the company. AMD will be restructuring again and will be slashing their global headcount by about 7%.
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.
