Subject: [PATCH v2 00/13] OpenSBI RISC-V AIA Support
Date: Wed, 9 Feb 2022 20:34:27 +0530 [thread overview]
Message-ID: <20220209150441.121729-1-apatel@ventanamicro.com> (raw)
The advanced interrupt architecture (AIA) extends the per-HART local
interrupt support. Along with this, it also adds IMSIC (MSI contrllor)
and Advanced PLIC (wired interrupt controller).
The latest AIA draft specification can be found here:
https://github.com/riscv/riscv-aia/releases/download/0.2-draft.28/riscv-interrupts-028.pdf
To test series, we require Linux from riscv_aia_v1 branch of
https://github.com/avpatel/linux.git
This series can be found riscv_aia_v2 branch at:
https://github.com/avpatel/opensbi.git
Changes since v1:
- Removed redundant CSR checks to detect AIA in PATCH2
- Typo fix in commit description of PATCH5
- Added more details about nascent_init() in comments of PATCH6
Anup Patel (13):
include: sbi: Add AIA related CSR defines
lib: sbi: Detect AIA CSRs at boot-time
lib: sbi: Use AIA CSRs for local interrupts when available
lib: sbi: Add sbi_trap_set_external_irqfn() API
lib: utils/irqchip: Allow multiple FDT irqchip drivers
include: sbi: Introduce nascent_init() platform callback
lib: sbi: Enable mie.MEIE bit for IPIs based on external interrupts.
