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.
