Subject: [PATCH V2 00/10] irqchip: Add LoongArch-related irqchip drivers
Date: Mon, 16 Aug 2021 15:52:42 +0800 [thread overview]
Message-ID: <20210816075252.4003406-1-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 adds some irqchip drivers for LoongArch, it is preparing
to add LoongArch support in mainline kernel, we can see a 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
V1 -> V2:
1, Remove queued patches;
2, Move common logic of DT/ACPI probing to common functions;
3, Split .suspend()/.resume() functions to separate patches.
Huacai Chen:
irqchip: Adjust Kconfig for Loongson.
irqchip/loongson-pch-pic: Add ACPI init support.
irqchip/loongson-pch-pic: Add suspend/resume support.
irqchip/loongson-pch-msi: Add ACPI init support.
irqchip/loongson-htvec: Add ACPI init support.
irqchip/loongson-htvec: Add suspend/resume support.
irqchip/loongson-liointc: Add ACPI init support.
irqchip: Add LoongArch CPU interrupt controller support.
irqchip: Add Loongson Extended I/O interrupt controller.
irqchip: Add Loongson PCH LPC controller support.
