AMD upstreamed firmware binaries for RDNA 4m (GFX 11.7) into linux-firmware.git, including GFX11.7.0/1, PSP 15.0.x, SDMA 6.1.4, VPE 2.0.0, and DCN 4.2, enabling Linux distributions to package ahead of launch. With this, RDNA 4m support aligns with a Linux 7.3 kernel and Mesa 26.2–26.3 ahead of the hardware release.
The Linux 7.2 merge window is closing with the kernel source tree surpassing 43.9 million lines of code (43,898,743 total) across 108,158 files, including about 33.65 million code lines, 5.03 million comments, and 5.21 million blank lines. AMDGPU/AMDKFD remains the largest driver at roughly 6.36 million lines. 7.1 stood at ~42.92 million. RC1 is expected later today as the 7.2 release unfolds.
Linux 7.3 will add a DRM color-format property to the DRM uAPI, initially supported by the AMDGPU driver, allowing user-space to request specific display color formats (AUTO, RGB, YUV 4:4:4/4:2:2/4:2:0); the feature is in drm-misc-next ahead of the 7.3 merge window, with patches also floated for Intel and Rockchip DRMs and related Wayland support.
Valve/Phoronix coverage notes that Timur Kristóf pushed patches to the AMDGPU driver to fix how harvested GCN 1.0 GPUs, like the Radeon HD 7870 XT (Tahiti LE), are handled by the Linux kernel. The updates address TCC cache configuration issues, enabling proper operation and out-of-the-box RADV Vulkan support for a card that historically didn’t work with open-source drivers, effectively reviving the HD 7870 XT on Linux nearly 14 years after its launch.
The AMDGPU kernel driver’s DC patches introduce a new Linux "power module" to manage display power features such as backlight and panel self-refresh (PSR), aiming to better match Windows behavior. The Display Manager will be refactored to use the power module for replay/PSR/backlight control and improved VRR handling, unifying power-saving behavior across Linux and Windows—benefiting laptops and mobile devices. The patches also enable driver power gating, but they’re not in Linux 7.1 and are expected to land in 7.2 later this year.
Linux 7.0-rc5 brings bug and regression fixes as the 7.0 cycle heads toward a stable release in April; notable changes include a Radeon/AMDGPU workaround for old GCN 1.0 Hainan GPUs and better Bluetooth support for the Logitech MX Master 4 mouse, with Torvalds noting rc5 is smaller than recent ones but still larger than typical rc5s, signaling a generally calm patch flow across drivers, networking, and core subsystems.
KDE Linux now provides Apple APFS read/write support via a DKMS module (linux-apfs-rw-dkms) pre-installed for easier access to data from macOS devices. It also includes a workaround for a long-standing AMDGPU freeze issue by setting amdgpu.dcdebugmask=0x10 to disable panel self-refresh (with slightly higher power usage). Additionally, Kup is added as KDE's backup tool and Flatpak language support is expanded as part of broader KDE Plasma improvements.
A Valve open-source developer fixed Linux boot/display issues on aging AMD GPUs (Sea Islands/GCN 1.1) by disabling memory clock dynamic power management and forcing the highest memory clock when DPM is off, a move that could help iMacs with Radeon R9 M380 and similar GPUs work better under the AMDGPU driver; upstream review is expected soon.
Linux 6.19 is the final update of its current kernel cycle, adding AMDGPU support for older GCN 1.0/1.1 GPUs (HD 7000 series), Vulkan via RADV, improved power management, and HDR through the DRM Color Pipeline, among other driver updates. Linus Torvalds also teased the next kernel as 7.0, which could bring further AMD GPU and hardware-support improvements. Rolling-release distros should receive the update soon via their update channels, while non-rolling distributions may take longer.
Linux 6.19 is out, bringing better support for older AMD GCN GPUs by defaulting to the AMDGPU driver, improving RADV compatibility, and introducing the Valve-backed DRM Color Pipeline API, along with Intel platform enhancements and other kernel/drivers and filesystem updates.
Linux 6.19 rolls out major hardware and performance gains: older AMD GCN GPUs switch to the AMDGPU driver for out-of-the-box RADV Vulkan support; the DRM Color Pipeline API is upstreamed for HDR gaming across AMDGPU, Intel, and VKMS; Steam Deck temperature monitoring; continued Intel platform enablement for Wildcat Lake and Nova Lake (with Xe3P graphics); LASS security; CASF adaptive sharpness upstreamed; EXT4 gains larger block sizes and online defragmentation; networking improvements up to 4x; and upstreamed ASUS Armoury and Uniwill laptop drivers to enhance keyboard, battery charging, RGB controls, and other laptop features.
Linux 6.19-rc7 adds a kernel continuity plan in case the main repo becomes unavailable, and includes several notable fixes: an AMDGPU revert, disabling the NEXT_BUDDY scheduler due to performance regressions, a long-standing page-fault handling correction, an ATA power-management regression fix, and expanded ASUS Armoury driver support, with Linus noting rc8 will follow the holiday period and the 6.19 stable release is expected around February 8 after a feature overview.
New patches for the open-source AMD Linux graphics driver enable HDMI VRR and Auto Low Latency Mode for gaming, adding HDMI gaming features (VRR, ALM), PCON changes, and improved VRR detection. The patches by Tomasz Pakuła use publicly known information and testing to work around HDMI Forum constraints, with the goal of upstreaming into the AMDGPU kernel.
Linux 6.19 introduces a ~30% performance boost for old AMD Radeon GCN 1.0/1.1 GPUs by defaulting to the modern AMDGPU driver, replacing the legacy Radeon driver, and enabling out-of-the-box Vulkan support, significantly improving support and performance for these older graphics cards.
AMD has submitted a set of fixes-oriented AMDGPU/AMDKFD kernel driver updates for the upcoming Linux 6.4 merge window, which includes minor feature updates such as GFX943 updates, S4 fixes for AMD APUs, DisplayPort fixes, RAS fixes, and various other fixes. The pull also includes FPO/FAMS work to improve display power savings, which is said to help reduce display power use with the latest RDNA3 graphics processors.
