[PATCH V4 00/22] arch: Add basic LoongArch support

From: Huacai Chen
Date: Mon Sep 27 2021 - 02:44:23 EST


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/latest/download/loongarch64-clfs-20210812-cross-tools.tar.xz

A CLFS-based Linux distro:
https://github.com/loongson/build-tools/releases/latest/download/loongarch64-clfs-system-2021-08-22.tar.bz2

Open-source tool chain which is under review:
https://github.com/loongson/binutils-gdb/tree/loongarch-2_37
https://github.com/loongson/gcc/tree/loongarch-12
https://github.com/loongson/glibc/tree/loongarch_2_34_dev

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

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

V1 -> V2:
1, Add documentation patches;
2, Restore copyright statements;
3, Split the big header patch;
4, Cleanup signal-related headers;
5, Cleanup incomplete 32-bit support;
6, Move the major PCI work to drivers/pci;
7, Rework Loongson64 platform support;
8, Rework lpj and __udelay()/__ndelay();
9, Rework page table layout config options;
10, Rework syscall/exception/interrupt with generic entry framework;
11, Simplify the VDSO/VSYSCALL implementation;
12, Use generic I/O access macros and functions;
13, Remove unaligned access emulation at present;
14, Keep clocksource code in arch since it is the "native clocksource";
15, Some other minor fixes and improvements.

V2 -> V3:
1, Rebased on 5.15-rc1;
2, Cleanup PCI code on V2;
3, Support multiple msi domain;
4, Support cacheable ioremap();
5, Use irq stack for interrupt handling;
6, Adjust struct ucontext and rt_sigframe;
7, Some other minor fixes and improvements.

V3 -> V4:
1, Rebased on 5.15-rc3;
2, Rework SMP support and remove legacy IPI;
3, Rework signal support and remove loongarch_abi;
4, Simplify phys_to_dma() and dma_to_phys();
5, Remove unused sys_mmap2() implementation;
6, Remove unused strncpy_user.S and strnlen_user.S;
7, Some other minor fixes and improvements.
