Linux 5.12 – Main Changes, Arm, MIPS and RISC-V Architectures

Linux 5.12

Linux 5.12 release was expected last Sunday, but Linus Torvalds decided to release one more release candidate, namely Linux 5.12-RC8, to “make sure things are all settled down“, so the latest Linux kernel is now expected this weekend.  Tihs should not yield any significant changes, so we can check what’s new in Linux 5.12, notably with regards to Arm, MIPS, and RISC-V architectures often used in SoC’s found in embedded systems. Around two months ago, the release of Linux 5.11 added support for Intel’s software guard extensions (SGX) and Platform Monitoring Technology (PMT), AMD “Van Gogh” and “Dimgrey cavefish” graphics processors, MIPI I3C host controller interfaces, and much more. Some interesting changes in Linux 5.12 include: Added support for ACRN hypervisor designed for IoT & embedded devices Added support for Playstation DualSense & Nintendo 64 game controllers, as well as Nintendo 64 data cartridges Dynamic thermal power management via a subsystem that allows the power usage of groups of devices […]

PiMod Zero for Raspberry Pi Zero SBC broadcasts video to your older NTSC TV (Crowdfunding)

PiMod Zero

Playing retro games or watching older movies on your Raspberry Pi Zero board over a modern digital video interface like HDMI clearly ruins the experience! 😉 While it should be possible to use to 2-pin reserved for video composite on the Raspberry Pi Zero to connect to an old TV, PiMod Zero HAT allows you to get back that retro feeling even with TVs lacking RCA composite and audio inputs by broadcasting video over VHF to older NTSC compatible televisions. PiMod Zero specifications: Operating frequency – VHF channels 2 and 3 (55.25 MHz and 61.25 MHz) Broadcast format – NTSC RF output power – 0.005 mW Impedance – 75 Ω Supply voltage – 5 V Power draw – 100 mW Dimensions – pHAT form factor The expansion board supports both color and B&W video, as well as audio.
