While the Linux kernel has supported Kernel Address Space Layout Randomization (KASLR) for a decade and a half in varying forms, it hasn't been supported for all hardware targets. Only in 2021 is the mainline Linux kernel seeing KASLR working for the MIPS-based Loongson64 platform...

Last week I provided some benchmarks looking at the IBM POWER9 mitigation for the L1 data cache needing to be flushed upon entering the kernel and on user accesses due to a recently disclosed vulnerability. POWER9 allows speculatively operating on validated data in the L1 cache, but when it comes to incompletely validated data paired with other side channels it could lead to local users potentially obtaining improper access to data in the L1 data cache. When benchmarking the impact on a POWER9 4c/16t CPU the overall impact was fairly modest while since then I fired up some benchmarks as well on a large POWER9 server with 44 cores / 176 threads to see the performance impact of this default Linux kernel change.

For the "Video Core Next 2" hardware like Navi as well as Renoir APUs, HEVC "sample adaptive offset" support has landed in Mesa 21.0...

[5 minut čtení] Real-time Linux, desktop postavený na Xfce, hromada audio a video programů a nově také spousta šikovných utilit z MX Linuxu a jistota stabilního vývoje. To je zbrusu nový AV Linux od Glena MacArthura. Několik měsíců trval vývoj nové, tak trochu přelomové verze oblíbené linuxové distribuce AV Linux. Oblíbené zejména mezi hudebníky a zvukaři, cílící však na všechny tvůrce multimédií, ať již možností běhu s realtime kernelem, nebo volbou myriády výchozích multimediálních aplikací.

Ever since AMD has been on a stellar trajectory with their hardware, users have been begging System76 to release an AMD Linux laptop... That's now finally coming with their upcoming Pangolin launch...

Mesa 20.3 has been released as the Q4'2020 open-source graphics driver update, primarily around providing OpenGL and Vulkan support on the likes of Intel and AMD Radeon graphics along with the reverse-engineered Nouveau support, many smaller drivers especially in the embedded space, and the growing list of CPU-based implementations and other translation efforts...

While we are still waiting to see what AMD might do for returning to open-source AGESA or better supporting Coreboot and the like, they are making some inroads with open-source firmware support -- beyond the context of Chromebooks where they continue to engage due to Google's engineering requirements. AMD is working to "align with the industry direction of open-source firmware stacks" with their initial focus being on open-source OpenBMC firmware support for their server platforms...
