DragonFlyBSD's AMDGPU kernel graphics driver continues to be a port of the AMDGPU Linux kernel driver. Their latest porting effort for AMD graphics on DragonFlyBSD is now enabling optional support for the GCN 1.1 "Sea Islands (CIK) graphics processors on this modern alternative to the prior Radeon kernel driver...

A proposal has been laid out for a new X.Org Server "main" Git branch to house their development going forward and cleaning up the development lapses over the past few years. Ultimately the hope is for having a new cleaned-up X.Org Server and XWayland Git branch for shipping new releases in 2026...

Pamatujete si devadesátky? V obývacích pokojích nám trůnily audio systémy lidově zvané Hi-Fi věže. Víte, že se dají koupit i dnes a že pořád skvěle hrají? Dnes vám popíšu jednu krabičku od Denonu.

Ukážeme si využití nástrojů gcov, gcovr a lcov při analýzách zdrojových kódů psaných v C, C++, Adě atd. Tyto nástroje dokážou zjistit, které příkazy jsou skutečně volány a které nikoli.

Last year Valve contractor Timur Kristóf managed to improve the AMDGPU driver enough for old GCN 1.0 Southern Islands and GCN 1.1 Sea Islands GPUs that with Linux 6.19 AMDGPU is now the default for those GPUs with better performance, RADV Vulkan out-of-the-box, and other benefits. He isn't done though improving the old GCN 1.0/1.1 era GPU support on this modern AMDGPU kernel driver - a new patch series posted today brings some power management fixes...

A new feature expected to be merged for the upcoming Linux 7.0 kernel cycle is adding an OPEN_TREE_NAMESPACE flag for the open_tree() system call.

Earlier this month we looked at the Dell Pro Max GB10 performance up against AMD's Ryzen AI Max+ "Strix Halo" with the superior performance for the green team for performance and power efficiency. For those wondering how the Dell Pro Max GB10 performance comes up for the much talked about NVIDIA GH200, here are some comparison benchmarks.

A new feature that appears ready for introduction in the upcoming Linux 6.20~7.0 kernel cycle is revocable resource management...

Support for newer HDMI features in the open-source AMD Linux graphics driver have been limited due to being blocked by the HDMI Forum. There are though some new HDMI gaming features being enabled via new AMDGPU kernel driver patches that are coming outside of AMD and based on public knowledge and/or "trying things out until they work/break" for functionality like HDMI Variable Refresh Rate (VRR) and Auto Low Latency Mode...

There have been a number of nice RADV driver Vulkan ray-tracing performance optimizations for Mesa in recent times... Here is yet another merge request now merged for Mesa 26.0 and helping deliver some nice performance uplift for ray-traced games on Linux. And, yes, this is yet another Valve contribution to this open-source AMD Radeon Linux graphics driver...
