LoongArch-specific interrupt controllers (similar to APIC) are added
in the next revision of ACPI Specification (current revision is 6.4),
which including CORE_PIC (CPUINTC), LIO_PIC (LIOINTC), EIO_PIC (EIOINTC),
HT_PIC (HTVECINTC), BIO_PIC (PCHINTC), LPC_PIC (PCHLPC) and MSI_PIC
(PCHMSI). This patch add their definition.

ACPI changes of LoongArch-specific interrupt controllers have already
been approved in the ECRs, and will be public in the next revision of
ACPI Specification.

These links are pretty useless without an account on uefi.org (most
people don't have one, and I certainly don't). Is there a link to
something *public*?


Sorry for inaccessible links, I take the patch from ACPICA, and the links here are intended to provide to ACPI maintainers when the patch was submitted to ACPICA.

The ACPI spec 6.5 is not published yet, and I have asked the ACPI spec work group, their reply is that I can not share the unpublished spec
draft link to the public, only using for member to review. I think
I can put the ECR(Engineering Change Request) file that described
LoongArch APICs on my github and put the link in the patch.

https://github.com/lvjianmin-loongson/acpica/blob/master/Add%20APIC%20Structures%20for%20Loongarch%20in%20MADT-rev3.pdf

From mail of the ACPI spec work group , the ACPI spec 6.5 will be published in late July or early August.


Thanks,
