More SpacemiT K3 RVA23 SoC Functionality Expected For Linux 7.1

Written by Michael Larabel in RISC-V on 10 April 2026 at 06:00 AM EDT. 5 Comments
The SpacemiT K3 is exciting as one of the first RISC-V RVA23 designs coming to market. For the Linux 7.0 kernel there is initial K3 support in the mainline kernel while the upcoming Linux 7.1 merge window is expected to land more K3 enablement.

SpacemiT Device Tree updates were sent out recently for queuing with the other DT changes ahead of the Linux 7.1 merge window, which is expected to open next week assuming no delays. With the DT updates are enabling more K3 functionality as well as some ongoing K1 enhancements.

The SpacemiT K3 with Linux 7.1 is set to enable I2C support, PMIC regulator handling, Ethernet support, Pinctrl / GPIO / clock, and full UART support. Having working Ethernet support is obviously quite important as is getting all the other bits into place so this RVA23 SoC can enjoy well-rounded, upstream kernel support.

Over on the K1 SoC side, Linux 7.1 is set to enable PCIe/USB, QSPI/SPI NOR, EEPOM, and LED support for the Milk-V Jupiter board.

More details on these SpacemiT Device Tree updates for Linux 7.1 can be found via this pull request.
