Subject: [PATCH v2 0/2] gdb: LoongArch: Add support for hardware watchpoint & breakpoint
Date: Tue, 11 Jun 2024 19:21:24 +0800 [thread overview]
Message-ID: <20240611112126.4882-1-lihui@loongson.cn> (raw)
LoongArch defines hardware watchpoint functions for fetch and load/store
operations. After the software configures the watchpoints for fetch and
load/store, the processor hardware will monitor the access addresses of
the fetch and load/store operations and trigger a watchpoint exception
when the watchpoint setting conditions are met.
After this series, watch/rwatch/awatch/hbreak command are supported.
Refer to the following document for hardware watchpoint and breakpoint:
https://loongson.github.io/LoongArch-Documentation/LoongArch-Vol1-EN.html#control-and-status-registers-related-to-watchpoints
Changes v1 -> v2:
- Fixed some code format.
- Use PLV3 privilege level in ctrl register to enable hardware breakpoint/watchpoint.
