Usage of current R1 ISA is inconsistent with the MIPS32 subtarget, little used and has limited utility for testing. Many distros target a minimum R2 ISA. Debian MIPS 32-bit/64-bit ports all use MIPS R2 ISA since Stretch, for example. Fedora's MIPS arch also targets the R2 ISA for 32-bit/64-bit. Widely used MIPS64 platforms like Octeon are based on the MIPS R2 ISA or later, and benefit from having a compatible test platform in OpenWRT. While Linux does support MIPS64 R1 targets, its usefulness for development and testing is limited. As an example, the modern Linux eBPF JIT requires a MIPS R2 ISA or later.

This Malta target is intended to be used with the Qemu emulator. It can be used to prototype an OpenWrt firmware for MIPS processors. One could also use it to troubleshoot MIPS applications without access to real hardware. To use the images built by OpenWrt with qemu, use the following commands: For the 32 bit little-endian image: qemu-system-mipsel -kernel bin/targets/malta/le/openwrt-malta-le-vmlinux-initramfs.elf -nographic -m 256 For the 32 bit big-endian image: qemu-system-mips -kernel bin/targets/malta/be/openwrt-malta-be-vmlinux-initramfs.elf -nographic -m 256 For the 64 bit little-endian image: qemu-system-mips64el -kernel bin/targets/malta/le64/openwrt-malta-le64-vmlinux-initramfs.elf -cpu MIPS64R2-generic -nographic -m 256 For the 64 bit big-endian image: qemu-system-mips64 -kernel bin/targets/malta/be64/openwrt-malta-be64-vmlinux-initramfs.elf -cpu MIPS64R2-generic -nographic -m 256 and enjoy the system bootin.
