Subject: [PATCH 00/19] arch: Add basic LoongArch support
Date: Tue,  6 Jul 2021 12:18:01 +0800	[thread overview]
Message-ID: <20210706041820.1536502-1-chenhuacai@loongson.cn> (raw)

LoongArch is a new RISC ISA, which is a bit like MIPS or RISC-V.
LoongArch includes a reduced 32-bit version (LA32R), a standard 32-bit
version (LA32S) and a 64-bit version (LA64). LoongArch use ACPI as its
boot protocol LoongArch-specific interrupt controllers (similar to APIC)
are already added in the next revision of ACPI Specification (current
revision is 6.4).

This patchset is adding basic LoongArch support in mainline kernel, we
can see a complete snapshot here:
https://github.com/loongson/linux/tree/loongarch-next

Cross-compile tool chain to build kernel:
https://github.com/loongson/build-tools/releases

Loongson and LoongArch documentations:
https://github.com/loongson/LoongArch-Documentation

LoongArch-specific interrupt controllers:
https://mantis.uefi.org/mantis/view.php?id=2203

Huacai Chen(19):
 LoongArch: Add elf-related definitions.
 LoongArch: Add writecombine support for drm.
 LoongArch: Add build infrastructure.
 LoongArch: Add common headers.
 LoongArch: Add boot and setup routines.
 LoongArch: Add exception/interrupt handling. 
 LoongArch: Add process management.

 LoongArch: Add system call support.
 LoongArch: Add signal handling support.
 LoongArch: Add elf and module support.
 LoongArch: Add misc common routines.
 LoongArch: Add some library functions.
 LoongArch: Add 64-bit Loongson platform.
 LoongArch: Add PCI controller support.
 LoongArch: Add VDSO and VSYSCALL support.
 LoongArch: Add multi-processor (SMP) support.
 LoongArch: Add Non-Uniform Memory Access (NUMA) support.
 LoongArch: Add Loongson-3 default config file.
