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.
A revert was merged into Linux 6.19 to fix a broken WiFi support for MediaTek MT792x hardware caused by a faulty patch that was accidentally introduced, resolving kernel panic and firmware loading issues, and this fix will be included in the upcoming Linux 6.19-rc4 release.
The Linux 6.19 kernel is set to include several new driver updates that expand support for various laptops, including Alienware, ASUS, and TUXEDO models, with improvements in device compatibility and functionality. These changes are expected to be merged into Linux 6.19-rc4.
The article compares the performance of Intel's modern Xe kernel driver versus the older i915 driver on Linux 6.19 for the Intel Arc A580 GPU, highlighting that the Xe driver offers design improvements and better support for modern architectures, but the A750 and A770 GPUs were not functional on Linux 6.19 during testing.
The article reports significant performance regressions and system hangs when using AMD's RDNA3 and RDNA4 GPUs on Linux 6.19, leading to the premature end of testing. Older AMD GPUs like the RX 6800 and RX 5700 XT were tested successfully on the latest Linux kernel and Mesa drivers, but newer cards faced critical stability issues with no current fix from AMD.
The Linux 6.19 kernel experienced scheduler regressions affecting performance, notably a 52.4% slowdown in certain benchmarks. A fix is currently being developed and tested to address these issues, aiming to restore performance improvements.
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.
The Linux 6.19 kernel includes a fix for the Seagate ST2000DM008 HDD that was causing the SATA bus to go offline due to issues with Link Power Management, preventing system instability. Disabling LPM for this drive resolves the problem.
Linux kernel 6.19 now includes stable support for GPIB (IEEE 488), a long-standing interface bus used in laboratory and microcomputer equipment since the 1970s, making it easier to connect and communicate with legacy and modern devices using this protocol.
Linux 6.19-rc1 introduces numerous features including PCIe link encryption, new drivers like ASUS Armoury, the DRM Color Pipeline API for HDR support, initial support for Tenstorrent Blackhole SoC, and enhanced graphics support for AMD, Intel, and ARM GPUs, along with various processor and performance improvements.
Linux 6.19 introduces significant driver updates to enhance support for laptops and gaming handhelds, including new drivers for Uniwill laptops, support for ASUS ROG, Lenovo Legion, and Ayaneo devices, along with features like rapid charging and power management improvements.
