Linux 6.4 release – Main changes, Arm, RISC-V and MIPS architectures

Linux 6.4 release

Linux 6.4 has just been released by Linus Torvalds on the Linux Kernel Mailing List (LKML): Hmm. Final week of 6.4 is done, and we’ve mainly got some netfilter fixes, some mm reverts, and a few tracing updates. There’s random small changes elsewhere: the usual architecture noise, a number of selftest updates, some filesystem fixes (btrfs, ksmb), etc. Most of the stuff in my mailbox the last week has been about upcoming things for 6.5, and I already have 15 pull requests pending. I appreciate all you proactive people. But that’s for tomorrow. Today we’re all busy build-testing the newest kernel release, and checking that it’s all good. Right? Released around two months ago, Linux 6.3 brought us AMD’s “automatic IBRS” Spectre defense mechanism, additional progress on the Rust front with User-mode Linux support (on x86-64 systems only), the NFS filesystem (both the client and server sides) gained support for […]

AMD Radeon PCIe graphics card tested with a Rockchip RK3588 SBC (Radxa Rock 5B)

AMD Radeon PCIe graphics card Rockchip RK3588 SBC

When Rockchip first introduced the Rockchip RK3399 processor with a PCIe interface people initially hoped they could connect graphics card, but those hopes were quickly squashed due to a 32MB addressing limit. However, the PCIe implementation on the newer Rockchip RK3588 processor does not have such a limitation, and last November, Radxa teased a demo with an AMD Radeon Pro WX 5100 PCIe graphics card connected to the Rock 5B SBC running the glxgears demo on the Radeon GPU. I couldn’t find any instructions to reproduce this setup, but this got Jasbir interested, and he tried to do a test of his own with the Radxa Rock 5B connected to an AMD Radeon R7 520 (XFX R7 250 low-profile) through an “M.2 Key M Extender Cable to PCIE x16 Graphics Card Riser Adapter” ($14 plus taxes on Aliexpress) and powered by an LR1007 120W 12VDC ATX board. The experiment was […]

Linux 6.3 release – Notable changes, Arm, RISC-V and MIPS architectures

Linux 6.3 release

Linux Torvalds has just announced the release of Linux 6.3 on the Linux Kernel Mailing List (LKML): It’s been a calm release this time around, and the last week was really no different. So here we are, right on schedule, with the 6.3 release out and ready for your enjoyment. That doesn’t mean that something nasty couldn’t have been lurking all these weeks, of course, but let’s just take things at face value and hope it all means that everything is fine, and it really was a nice controlled release cycle. It happens. This also obviously means the merge window for 6.4 will open tomorrow. I already have two dozen pull requests waiting for me to start doing my pulls, and I appreciate it. I expect I’ll have even more when I wake up tomorrow. But in the meantime, let’s enjoy (and test) the 6.3 release. As always, the shortlog […]

100ASK-V853-Pro – A feature-rich Allwinner V853 board designed for AI vision applications

100ASK V853 Pro

The 100ASK-V853-Pro board is a development kit consisting of an Allwinner V853 system-on-module board (SoM) and a feature-rich carrier board with a large number of interfaces. Allwinner V853 supports up to 1TOPS of NPU computing power and is mainly for AI vision application development. The core board contains a DDR and eMMC as well as a PMU chip (AXP2101) and is connected to the carrier board through a board-to-board connector. All the functional resources of the V853 are drawn out through the carrier board. The carrier board comes with 2-channels CSI camera interfaces as well as RGB and MIPI DSI display interfaces. Although 1 TOPS of AI computing power is not outstanding, the NPU can still be used to accelerate AI vision applications at the edge. The board also comes with four USB 2.0 ports (two Type-A, two Type-C), an 100Mbps Ethernet port, a 22-pin header for expansion, and five […]
