AMD Updates FreeSync Certification Requirements For New Monitors & TVs

AMD's FreeSync adaptive synchronization technology for displays has come a long way since its 2015 debut and enjoying robust industry adoption. Given the increasing refresh rates of today's TVs and monitors, AMD has rolled out new tier requirements for FreeSync, FreeSync Premium, and FreeSync Premium Pro moving forward.

AMDGPU Linux Driver No Longer Lets You Have Unlimited Control To Lower Your Power Limit
AMDGPU Linux Driver No Longer Lets You Have Unlimited Control To Lower Your Power Limit

The AMDGPU Linux driver up until the recent Linux 6.7 kernel release has let you lower the power limit of your graphics card with, well, no limits... This has allowed AMD Radeon Linux users to limit their GPU power draw when desiring for power/efficiency reasons. But since Linux 6.7 they've begun enforcing a lower-power limit set by the respective graphics card BIOS. Users petitioned to have this change reverted but in the name of safety this lower-limit enforcement will stand.

Mesa 24.1 Lands Support For GFX11.5.1 "RDNA3 Refresh" Variant
Mesa 24.1 Lands Support For GFX11.5.1 "RDNA3 Refresh" Variant

When it comes to the AMD "RDNA3 Refresh" GFX11.5 open-source driver support, to date it's mostly been focused on the GFX 11.5.0 (GFX1150) IP while now being enabled within Mesa 24.1 for the open-source RadeonSI/RADV drivers is support for a GFX 11.5.1 (GFX1151) variant.

LACT 0.5.3 Released For Managing AMD Graphics Cards Under Linux
LACT 0.5.3 Released For Managing AMD Graphics Cards Under Linux

With the absence of any official AMD Radeon graphics control panel / settings GUI for Linux enthusiasts/gamers, there are several open-source projects striving to be a viable Radeon GUI control area for Linux gamers/enthusiasts. LACT 0.5.3 was released this weekend as the newest version of this option for AMD Radeon information reporting, GPU overclocking, fan control, power/thermal monitoring, and additional power state configurations.

AMD FreeSync Video Facing Retirement In Linux 6.9
AMD FreeSync Video Facing Retirement In Linux 6.9

Back in 2020 AMD rolled out a video mode optimization for FreeSync on Linux, continued being revised in 2021, FreeSync Video mode then attempted by default in 2022 but then was reverted and then only last year FreeSync Video enabled by default. But now come Linux 6.9, the feature appears to be effectively retired.

HDMI Forum Rejects Open-Source HDMI 2.1 Driver Support Sought By AMD
HDMI Forum Rejects Open-Source HDMI 2.1 Driver Support Sought By AMD

One of the limitations of AMD's open-source Linux graphics driver has been the inability to implement HDMI 2.1+ functionality on the basis of legal requirements by the HDMI Forum. AMD engineers had been working to come up with a solution in conjunction with the HDMI Forum for being able to provide HDMI 2.1+ capabilities with their open-source Linux kernel driver, but it looks like those efforts for now have concluded and failed.

Building An AMD HIP Stack From Upstream Open-Source Code
Building An AMD HIP Stack From Upstream Open-Source Code

While AMD ships pre-built ROCm/HIP stacks for the major enterprise Linux distributions, if you are using not one of them or just want to be adventurous and compile your own stack for building HIP programs for running on AMD GPUs, one of the AMD Linux developers has written a how-to guide.

AMD's Brotli-G 1.0 Released With CPU & GPU Decompression
AMD's Brotli-G 1.0 Released With CPU & GPU Decompression

Back in November 2022 AMD announced Brotli-G for GPU-accelerated Brotli compression. Brotli has proven very worthwhile for compressing web assets and other material while AMD's Brotli-G modifies the bitstream format to be more optimal for handling by GPUs rather than just relying on CPU (de)compression. Today Brotli-G 1.0 was finally released.

GCC 14 Compiler Might Have AMD RDNA3 GPU Support "Working For Most Purposes"
GCC 14 Compiler Might Have AMD RDNA3 GPU Support "Working For Most Purposes"

Earlier this month the GCC 14 compiler landed initial support for AMD RDNA3 "GFX11" graphics processors as part of the GNU Compiler Collection's OpenMP device offloading support for GPU compute. That initial support was rather basic but a follow-up patch has the possibility of making the RDNA3 (GFX11) support "working for most purposes" and will hopefully still be merged in time for the GCC 14.1 stable release.

AMD's OpenGL Linux Driver Already Scored A Nice Performance Win For 2024
AMD's OpenGL Linux Driver Already Scored A Nice Performance Win For 2024

While much of the focus by graphics vendors these days is on their Vulkan driver support/performance and less so about OpenGL in 2024, AMD's open-source RadeonSI Gallium3D driver for Linux systems is still showing no signs of slowing down and still scoring more performance victories.

The Open-Source ATI R300 Graphics Driver Is Still Being Improved Upon In 2024

It's been over twenty years since the ATI Radeon R300 series was introduced but thanks to the open-source Mesa Gallium3D OpenGL driver, there continues to be new improvements made to this driver for these aging Radeon graphics cards on Linux. A few hundred lines of code were merged today for further enhancing the ATI R300 Gallium3D driver in 2024.

AMD Enables VCN Region Of Interest "ROI" Video Encoder Support For Linux GPU Drivers

While not talked about as much as the AMD open-source OpenGL and Vulkan drivers for Linux, AMD's multimedia stack on Linux continues to be improved upon for supporting new use-cases with AMD-based Linux deployments continuing to come up in the embedded space for all different applications like in-vehicle infotainment systems. The newest AMD video acceleration feature to now be wired up to their open-source Mesa code is enabling region of interest (ROI) encoding functionality.

AMD Stages The Radeon Graphics Color Management Code For Linux 6.8
AMD Stages The Radeon Graphics Color Management Code For Linux 6.8

On Friday in addition to Intel submitting their new Xe kernel graphics driver to DRM-Next ahead of Linux 6.8, the red team sent in their latest AMDGPU/AMDKFD kernel driver changes ahead of this next kernel cycle. Exciting on the AMD side is landing the AMD color management properties support! But on the downside, it's compile-time disabled for the time being.

LACT Is The Newest AMD Radeon GUI Control Panel For Linux
LACT Is The Newest AMD Radeon GUI Control Panel For Linux

While the open-source AMD Radeon Linux graphics driver is well received by the community, one of the longest sought features has been an official GUI control panel for managing the driver settings and the like under Linux with ease. AMD for their part exposes much of the same tunables available under Windows but is left to just command-line controls or software to poke different ioctls directly. LACT is now the newest open-source option for those wanting an AMD graphics driver control panel for Linux.
