Hi Daniel and all,
The KVM patches have been reviewd and are in the queue.
https://lore.kernel.org/all/20240402062628.5425-1-duc...@eswincomputing.com/
Could you please review in the QEMU side ?
Then I will rebase this series with your comments.
Some Notes:
1. As the first stage, only the software breakpoints is implemented.
2. A 'corner case' in which the debug exception is not inserted by the
debugger, need to be re-injected to the guest. This is not handled yet
in this series.
Aside from the comments I made in patch 1 w.r.t checks that (perhaps) can be
moved
to kvm-all.c, it looks good to me.
Since you're changing kvm-all.c we'll need Paolo to ack the changes in patch 1,
so
feel free to wait for him to take a look before sending v2.
Thanks,
Daniel
Thanks,
Chao

Hi,
It seems that we still need the kernel KVM side to be sorted out first [1],
so I believe we should wait a bit until we can review this RFC. Otherwise we
might risk reviewing something that has to be changed later.

This series implements QEMU 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 QEMU 8.2.0-rc4 and is also available at:
https://github.com/Du-Chao/qemu/tree/riscv_gd_sw
This is dependent on KVM side changes:
https://github.com/Du-Chao/linux/tree/riscv_gd_sw
Chao Du (4):
target/riscv/kvm: add software breakpoints support
target/riscv/kvm: implement kvm_arch_update_guest_debug()
target/riscv/kvm: handle the exit with debug reason
linux-headers: enable KVM GUEST DEBUG for RISC-V
