Subject: [PATCH 46/78] target/loongarch/kvm: Add software breakpoint support
|
|
|
|
With KVM virtualization, debug exception is injected to guest kernel
|
|
rather than host for normal break intruction. Here hypercall
|
|
instruction with special code is used for sw breakpoint usage,
|
|
and detailed instruction comes from kvm kernel with user API
|
|
KVM_REG_LOONGARCH_DEBUG_INST.
|
|
|
|
Now only software breakpoint is supported, and it is allowed to
|
|
insert/remove software breakpoint. We can debug guest kernel with gdb
|
|
method after kernel is loaded, hardware breakpoint will be added in later.
