The LoongArch architecture support for these Chinese processors continue seeing better support with the upstream Linux kernel.
The LoongArch CPU port updates for the Linux 6.12 kernel have been merged. Among the changes are adding ACPI Boot Graphics Record Table (BGRT) for LoongArch to enjoy the better Plymouth boot splash screen integration for systems/motherboards having a logo to display as part of the boot process. LoongArch also now supports Linux’s generic CPU vulnerabilities reporting infrastructure.
The LoongArch port also now sets the ARCH_HAS_SET_MEMORY and ARCH_HAS_SET_DIRECT_MAP kernel features, improves its hardware page table walker, and other changes.
