Subject: [PATCH 0/3] riscv: interrupt-controller: Add T-HEAD C900 ACLINT SSWI
Date: Fri, 4 Oct 2024 16:05:54 +0800 [thread overview]
Message-ID: <20241004080557.2262872-1-inochiama@gmail.com> (raw)
New version of T-HEAD C920 implement a fully featured ACLINT[1] device
(This core is used by Sophgo SG2044). This ACLINT device provides a
SSWI field to support fast S-mode IPI. This SSWI device is like the
MSWI device in CLINT/ACLINT, but for S-mode. The only thing is different
from the draft is that the T-HEAD version SSWI needs to write 0 on the
SSWI address to clear the IPI.
Add full support for T-HEAD C900 SSWI device.
