Linux 5.13 To Allow For OpenBMC Development With A Lower-Cost ASRock Rack Motherboard

The Linux Foundation's OpenBMC project to provide an open-source BMC firmware stack is quite exciting for freeing this low-level aspect of servers, but finding a supported motherboard that works well with OpenBMC can be a challenge at this stage. Fortunately, Linux 5.13 is set to support a lower-cost motherboard option in hopes of boosting OpenBMC development/usage.

Vulkan Video Arrives For New Industry-Standard Video Encode/Decode

For years we have been eager to learn more about the long mentioned Vulkan Video API, which was supposed to come in H1-2020, but now has finally arrived with today's v1.2.175 update in provisional form. The new Vulkan Video extensions allow for GPU-accelerated video encode/decode. The initial public work is treated as a provisional specification and with limited codec coverage but will be expanded upon in time.

Intel Rocket Lake Target Added To GCC 11

While Intel is often very proactive in adding new CPU families to the open-source GCC and LLVM/Clang compilers where it tends to land a year or more in advance of the processors actually shipping, occasionally there are slipups. Today in fact the "Rocket Lake" support finally was merged into GCC 11 days ahead of that compiler release and after the CPUs were already launched at the end of March.

Linux 5.13 Will Stop Restricting CPU Power Metrics Access For AMD Energy Driver

Following the PLATYPUS discovery last year that CPU energy information could be used for possible side channel attacks, the Intel RAPL counters were not only restricted to root but the "amd_energy" driver for exposing CPU energy information on supported Zen series CPUs was also dialed back to root-only in the name of security. Linux 5.13 is introducing a new mechanism so AMD CPUs will be able to still read the energy counters even if not operating as root.

Dynatron A38 Performance For Cooling 280 Watt AMD EPYC CPUs

Announced in March by Dynatron was their A38 CPU cooler for AMD Ryzen Threadripper and EPYC processors. This heatsink fan is rated for cooling up to 280 Watt SP3/sTRX4/TR4 processors making it capable of cooling even the newest high-end EPYC "Milan" processors with the EPYC 75F3 and 7763 processors. Here are some initial benchmarks of this cooler with the AMD EPYC 7763 server processor.

SiFive FU740 PCIe Support Queued Ahead Of Linux 5.13

Arguably the most interesting RISC-V board announced to date is SiFive's HiFive Unmatched with the FU740 RISC-V SoC that features four U74-MC cores and one S7 embedded core. The HiFive Unmatched also has 16GB of RAM, USB 3.2 Gen 1, one PCI Express x16 slot (operating at x8 speeds), an NVMe slot, and Gigabit Ethernet. The upstream kernel support for the HiFive Unmatched and the FU740 SoC continues.
