Patched Linux 5.11 Continues Looking Great For AMD Ryzen/EPYC Performance

While the initial AMD Linux 5.11 performance regression written about at the end of last year was of much concern given the performance hits to AMD Zen 2 / Zen 3 processors with the out-of-the-box "Schedutil" governor, with a pending patch the regression is not only addressed but in various workloads we continue seeing better performance than even compared to Linux 5.10. Here is the latest from several more days of extensive performance testing.

DIN-rail gateway offers dual LAN and dual RS485

The Unipi Gate G110 and G100 are PLC-ready DIN-rail gateways that run Linux on a quad -A53 SoC with 16GB eMMC, GbE and 10/100 LAN ports, and up to 2x RS485 ports with modular extensions. Czech based Unipi, which started out in 2014 with a Raspberry Pi based UniPi automation controller board and followed up with products including an Allwinner H5-based Axon automation controller, has now launched the $243 Unipi Gate G100 and $272 Unipi Gate G110 DIN-rail gateways.

Telematics gateway connects with Iridium, GPS, 4G, WiFi/BT, and 433MHz RFID

Appareo’s IP67-rated, -40 to 75°C tolerant “Gateway 370” telematics gateway runs Linux on a Cortex-A9 SoC and supplies Iridium SBD, 433MHz (RFID), 4G LTE, WiFi/BT, and GPS plus LAN, BroadR-Reach, DIO, and CAN links. Fargo, ND based Appareo has launched a wireless telematics control unit (TCU) for heavy machinery in applications such as construction and agriculture. The Gateway 370 is based on a Gateway 270 that Appareo announced last May. That earlier model similarly provides Yocto-derived Linux with Docker container support on an unnamed dual-core, Cortex-A9 SoC — probably the i.MX6 Dual or DualLite.
