CPU watchpoints can be use by non-TCG accelerators.
KVM uses them:
$ git grep CPUWatchpoint|fgrep kvm
target/arm/kvm64.c:1558: CPUWatchpoint *wp = find_hw_watchpoint(cs, debug_exit->far);
target/i386/kvm/kvm.c:5216:static CPUWatchpoint hw_watchpoint;
target/ppc/kvm.c:443:static CPUWatchpoint hw_watchpoint;
target/s390x/kvm/kvm.c:139:static CPUWatchpoint hw_watchpoint;
See for example commit e4482ab7e3 ("target-arm: kvm - add support
for HW assisted debug"):
This adds basic support for HW assisted debug. The ioctl interface
to KVM allows us to pass an implementation defined number of break
and watch point registers. [...]
This partially reverts commit 2609ec2868e6c286e755a73b4504714a0296a.
