After dealing with the Intel Alder Lake P GuC firmware breakage around Linux 5.19 Git that is now to be addressed by the upstream Intel developers, it was on to performance testing the shiny new Core i7 1280P with this kernel due to be released as stable within the next two weeks... For those concerned about maximum performance, there was a glaring performance regression for this Alder Lake P on the new kernel being released as stable later this month. Well, a default change in performance/behavior at least but the power efficiency / performance-per-Watt tended to be better on this new kernel.

Asahi Linux has issued an update with initial support for the Mac Studio powered by the M1 Ultra SoC as well as having initial (experimental) suppoirt for the new Apple M2 hardware...

Stemming from my article last week noting how Linux 5.19 Git broke Intel Alder Lake P graphics support due to requiring new firmware while not retaining backwards compatibility with the existing Intel GuC firmware, a solution is still being worked on prior to Linux 5.19 final whether it be a revert or the proposed patch working on GuC v69/70 firmware compatibility. Linux firmware guidelines are also being proposed to ensure kernel developers in the future don't try to break firmware support guarantees...

Linus Torvalds just released Linux 5.19-rc7 following a busy week due to the Retbleed security mitigation and not only the CPU overhead performance impact it puts on users but the mess it has on kernel development especially when it comes to embargoed issues that make the patches difficult to review/test well prior to embargo lift...

Following some weekend benchmarks here are more complementary numbers on the Retbleed mitigation performance benchmark costs. These additional numbers are on a Zen 2 based AMD Ryzen 7 4800U APU that has been common both to laptops as well as embedded/low-profile devices for thin client computing, IoT / edge use-cases, and more...

Due to the new "Retbleed" security mitigation further hurting CPU performance for affected processors, Intel engineers have revisited work on call depth tracking mitigation as an alternative to the Indirect Branch Restricted Speculation (IBRS) mitigation to help in lowering the overhead costs...

As of this week in Mesa 22.2, the open-source Radeon Vulkan driver "RADV" has added support for the VK_NV_device_generated_commands extension. This NVIDIA-created extension that has been around for a few years with their hardware allows for the GPU to generate some of the most frequent rendering commands on the hardware itself...
