[ Side note: All the contents in this branch look fine to me and I think we are
better off with them in 5.19 than later, mainly because it allows merging the
glibc port sooner. On the other hand, the way here has been somewhat irregular
and rushed, and as explained in the tag it doesn't actually boot. If
you have any
doubts about the submission, it can obviously wait for another release and get
done properly then. - Arnd ]

Add partial Loongarch architecture code
This is the majority of the loongarch architecture code, including
the final system call interface and all core functionality.
It still misses three sets of peripheral but vital patches to add
support for other subsystems, which have yet to pass review:
- The drivers/firmware/efi stub for booting from a standard UEFI
firmware implementation. Both the original custom boot interface
and a draft implementation of the EFI stub did not make it, so
it is currently impossible to boot the kernel, until the
loongarch specific portions get accepted into the UEFI subsystem
- The drivers/irqchip/irq-loongson-*.c drivers are shared with the
MIPS port, but currently lack support for ACPI based booting,
which will get merged through the irqchip subsystem.
- Similarly, the drivers/pci/controller/pci-loongson.c needs to be
modified for ACPI support, which will be merged through the
PCI subsystem.
While the port cannot actually be used before all the above are
merged, having it in 5.19 helps to establish the user space ABI
for the libc ports to build on, and to help any treewide changes
in the mainline kernel get applied here as well. A gcc-12 based
tool chains for build testing is now included in
https://mirrors.edge.kernel.org/pub/tools/crosstool/.
Original description from Huacai Chen at
https://lore.kernel.org/lkml/20220603072053.35005-1-chenhuacai@loongson.cn/:
"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:

Thanks to Arnd; you have reviewed as many as 15 versions of the patchset, taught me step by step, from large refactoring to code details. These days, I have disturbed you much and may make you feel tired. With the port mainlined, finally we could stop rushing things. Thanks to Xuerui, for helping me a lot, from code design, documents writing to communication and coordination. You have sacrificed so much of your own time, and solved so many troubles caused by my terrible English. I'm happy to know that you are willing to become a regular reviewer of LoongArch. Thanks to Ard and Marc, for the in-depth conversations that helped Loongson and LoongArch to improve, and for pointing out how to drop the more controversial parts, enabling the "good parts" to be upstreamed in time. Thanks to Linus, for starting this great project and the continued maintenance, making developers in our large community able to collaborate with each other. Thanks to all the community members who have helped: Steven, Jiaxun, Guo Ren, Ruoyao, Eric, Jason, Javier, Haowen, Bagas, who have commented, and certainly others that helped outside of the mailing lists. Thanks to my leaders, my colleagues, my family and my friends. Most of your contributions are unsung. Honor belongs to all of us. Thank all of you again! Huacai [P.S. this letter was proofread and lightly edited by Xuerui too, but he chose to mostly keep intact the vibe of a traditional, distinctly Chinese-style thank-you letter, instead of effectively rewriting the whole thing. This is not code or documentation after all...] On Sat, Jun 4, 2022 at 2:26 AM Arnd Bergmann <arnd@kernel.org> wrote: > > The following changes since commit 50fd82b3a9a9335df5d50c7ddcb81c81d358c4fc: > > Merge tag 'docs-5.19-2' of git://git.lwn.net/linux (2022-06-02 15:36:06 -0700) > > are available in the Git repository at: > > git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic.git > tags/loongarch-5.19 > > for you to fetch changes up to 8be4493119b0aedf7dd61e1ca520fb398537b53e: > > MAINTAINERS: Add maintainer information for LoongArch (2022-06-03 > 20:09:29 +0800) > > [ Side note: All the contents in this branch look fine to me and I think we are > better off with them in 5.19 than later, mainly because it allows merging the > glibc port sooner.
