&gt; 
&gt; For legal reasons, we can't pre-release any upcoming ACPI spec changes in ACPICA.
That's OK, we can wait.

&gt; Subject: [PATCH 2/3] ACPICA: MADT: Add LoongArch APICs support
&gt; 
&gt; 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 and handlings.
