Below is the updated version of the patch adding debugging support to WHPX. It incorporates feedback from Alex Bennée and Peter Maydell regarding not changing the emulation logic depending on the gdb connection status. Instead of checking for an active gdb connection to determine whether QEMU should intercept the INT1 exceptions, it now checks whether any breakpoints have been set, or whether gdb has explicitly requested one or more CPUs to do single-stepping. Having none of these condition present now has the same effect as not using gdb at all. Message-Id: <0e7f01d82e9e$00e9c360$02bd4a20$@sysprogs.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
