AMDGPU ISP Firmware Upstreamed In linux-firmware.git
AMDGPU ISP Firmware Upstreamed In linux-firmware.git

It was just earlier this month that AMD Linux kernel graphics driver patches appeared for introducing a new ISP hardware block for Image Signal Processing with new AMD APUs. Already the AMDGPU ISP firmware has appeared in linux-firmware.git indicating that this "ISP" block may be coming in hardware quite soon if not already quietly found within some products.

ZLUDA Has Been Seeing New Activity For CUDA On AMD GPUs
ZLUDA Has Been Seeing New Activity For CUDA On AMD GPUs

Back in February I wrote about AMD having quietly funded the effort for a drop-in CUDA implementation for AMD GPUs built atop the ROCm library. This was an incarnation of ZLUDA that originally began as a CUDA implementation for Intel GPUs using oneAPI Level Zero. While AMD discontinued funding ZLUDA development earlier this year, this CUDA implementation for AMD GPUs is continuing to see some new code activity.

AMD Posts RDNA3+ Firmware Files For Linux Users
AMD Posts RDNA3+ Firmware Files For Linux Users

This weekend AMD upstreamed a number of new AMDGPU firmware files into the linux-firmware.git repository that serves as a basis for all of the binary firmware/microcode files used by the Linux kernel drivers. This big set of new AMDGPU firmware files is likely for the upcoming RDNA 3.5 / "RDNA3 refresh" / RDNA3+ as it appears will be called updated RDNA3 graphics for upcoming AMD Ryzen SoCs.

Open-Source "Terakan" Vulkan Driver For Radeon HD 6000 Series Shown On Windows
Open-Source "Terakan" Vulkan Driver For Radeon HD 6000 Series Shown On Windows

The past year there's been an independent open-source driver developer working on "Terakan" as a Vulkan driver for old Radeon HD 6000 series GPUs. These pre-GCN GPUs never received any official Vulkan driver support from AMD but thanks to open-source and a strong desire to pull off such a feat, Vitaliy Kuzmin "Triang3l" has been pursuing this challenge and has been pulling off some basic results. The work so far has been predominantly been carried out with the open-source Linux graphics stack while this weekend the Terakan driver was demonstrated under Microsoft Windows.

AMD Working To Release MES Documentation & Source Code
AMD Working To Release MES Documentation & Source Code

Following up on their tweet earlier this week that they would be working to open-source more of their GPU software stack and hardware documentation, AMD now says they will be releasing documentation followed by the source code for their Micro-Engine Scheduler (MES) IP block found within Radeon GPUs.

Mesa 24.1 Merges AMD Radeon VPE 1.1 Engine Support
Mesa 24.1 Merges AMD Radeon VPE 1.1 Engine Support

AMD open-source Linux driver patches posted last summer enabled the new "VPE" IP block as a general purpose copy engine for future AMD GPUs. This VPE block might premiere in the upcoming AMD RDNA3.5 refresh (RDNA3+) integrated graphics but in any event AMD is already working on the incrementally improved VPE 1.1 IP with that now being supported by the Mesa 24.1 RadeonSI driver code.

Tiny Corp Changes Course Yet Again With Plans To Offer AMD Radeon GPUs
Tiny Corp Changes Course Yet Again With Plans To Offer AMD Radeon GPUs

It was just last week that Tiny Corp put their AMD Radeon graphics powered compute boxes "on hold" after being frustrated with the lack of select firmware source code and ultimately hitting various bugs. This wasn't the first time they had put their AMD Radeon graphics plans on-hold or dismissed it outright. With the start of the new week now comes plans to re-introduce an AMD Radeon graphics option for their compute boxes alongside their recently announced NVIDIA GeForce RTX 4090 compute rigs.

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.

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.

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.
