[PATCH v2 10/11] gdbstub: move breakpoint logic to accel ops |
|
Date: |
Mon, 26 Sep 2022 14:39:03 +0100 |
As HW virtualization requires specific support to handle breakpoints
lets push out special casing out of the core gdbstub code and into
AccelOpsClass. This will make it easier to add other accelerator
support and reduces some of the stub shenanigans.
