From our Ampere Altra Max M128-30 Linux performance preview earlier this week, one of the questions a number of readers were wondering about and a question I also still had open was on the Altra Max pricing... I've now received the current price list and actually comes in much lower than expected for a 128-core CPU in 2021...

Succeeding Mesa 21.2.2 from earlier this month that was a much delayed and in turn very large release, Mesa 21.2.3 is out today and it's on the quieter side...

While the Linux kernel is increasingly supporting the use of Zstd for various compression purposes, the current Zstd code within the kernel is out-of-date and efforts so far to re-base it against the closer to upstream Zstd state have been stalled. Fortunately, a new attempt at getting the Zstd code updated for the Linux kernel will be published soon...

Since July we've seen AMD open-source driver engineers posting code for "Cyan Skillfish" as an APU with Navi 1x graphics. While initial support for Cyan Skillfish was merged for Linux 5.15, it turns out the display code isn't yet wired up due to being a different DCN2 variant for its display block...

A batch of feature updates was submitted today for DRM-Next of early feature work slated to come to the next version of the Linux kernel...

There has been talk of Intel moving to offer more license-able/opt-in features for hardware capabilities found within a given processor as an upgrade. We are now seeing the Linux signs of that support coming with a driver for "Intel Software Defined Silicon" to allow for the secure activation of such features baked into the processor's silicon but only available as an up-charge option...

With the in-development Linux 5.15 kernel there is now support for ACPI Platform Profiles on supported ASUS laptops. This ASUS laptop platform profile support joins the likes of HP, Dell, and Lenovo laptops already having this support exposed under Linux that allows users to control their power/performance preference. Here are some tests with the ASUS ROG Strix G15 AMD Advantage laptop with the platform profile options under Linux 5.15.

Over the original GNU Wget, Wget2 is faster, supports more protocols especially around HTTP/2 and compression, supports multi-threading / parallel connections, and other improvements...

Earlier this month AMD published their "amd-pstate" Linux driver that leverages ACPI CPPC data to make more informed CPU frequency scaling decisions with an aim to boost the performance-per-Watt for Zen 3 (and eventually Zen 2) processors on Linux. The second spin of that "amd-pstate" Linux kernel driver is now available for testing...

It was just last month when ~3.5M IOPS per-core was impressive with the code for Linux 5.15 to further push Linux's I/O limits. Now for code likely to be included in Linux 5.16 it's currently at 3.8M IOPS with a single tread...

For several years now Facebook engineers have been working on BOLT as a way to speed-up Linux/ELF binaries. This "Binary Optimization and Layout Tool" is able to re-arrange executables once profiled to generate even faster performance than what can be achieved by a compiler's LTO and PGO optimizations. One of the latest BOLT efforts has been on optimizing the Linux kernel image...

Earlier this month Intel engineers posted their initial Linux kernel enablement around x86 User Interrupts with this feature premiering with Xeon "Sapphire Rapids" CPUs. As implied by the name, the User Interrupt functionality allows for interrupts to bypass the kernel for more efficient, low-latency, low-utilization interrupts being received by other user-space tasks. Intel talked more about User Interrupts this week at LPC2021...
