Subject: [RFC PATCH 0/3] RISC-V: KVM: Guest Debug Support
Date: Thu, 21 Dec 2023 09:49:59 +0000	[thread overview]
Message-ID: <20231221095002.7404-1-duchao@eswincomputing.com> (raw)

This series implements KVM Guest Debug on RISC-V. Currently, we can
debug RISC-V KVM guest from the host side, with software breakpoints.

A brief test was done on QEMU RISC-V hypervisor emulator.

A TODO list which will be added later:
1. HW breakpoints support
2. Test cases

This series is based on Linux 6.7-rc6 and is also available at:
https://github.com/Du-Chao/linux/tree/riscv_gd_sw

The matched QEMU is available at:
https://github.com/Du-Chao/qemu/tree/riscv_gd_sw
