The various SoC and platform Device Tree additions were sent out today for the Linux 7.0 kernel. Easily most exciting on the SoC side this cycle among the ARM and RISC-V changes is getting support ready for the SpacemiT K3 RVA23 SoC.
Sent out today were the four pull requests of all the SoC feature changes for Linux 7.0. Highlights include:
– SpacemiT Key Stone K3 support for that 8-core RISC-V processor and the first widely-available RVA23 implementation. Great seeing the SpacemiT K3 making it to the mainline kernel with this chip being important for driving RISC-V RVA23 adoption. Hopefully we see some SpacemiT K3 haardware soon in the lab for testing. The eight RISC-V RVA23 cores clock up to 2.4GHz.
– Qualcomm Snapdragon 8 Elite Gen 5 “Kaanapali” SoC support with its eight Oryon CPU cores.
– Support for the cut-down NXP i.MX8QP and i.MX952 SoCs.
– Realtek Kent family support with the rtd1501s, rtd1861b and rtd1920 chips. This hardware is for settop boxes and NAS devices.
– Snapdragon 7s Gen 3 SM7635 SoC support as used by the Fairphone Gen 6 smartphone.
– New firmware drivers for the Trusted Execution Environment (TEE) subsystem plus updates to the AMD, NXP, and Qualcomm TEE drivers.
– Mediatek MT8196 dynamic voltage and frequency scaling (DVFS) power management.
– Qualcomm SCM firmware and MDT loading work as part of the Snapdragon X2 “Glymur” work.
– Enabling Apple Silicon drivers as part of the ARM64 default kernel configuration.
More details on these SoC changes via the pull requests.
