Now user can remove extra breakpint and continue. v3->v4 - remove hardcoding for size of instruction in software breakpoint - remove unnecessary assert in debug handler - Corrected assert comparison in insert_breakpoint() v2->v3 - Sharing of code for book3s support (which may come in future) - Initializing number of hw breakpoint/watchpoints from KVM world - Other minor cleanup/fixes v1->v2: - use kvm_get_one_reg() for getting trap instruction - factored out e500 specific code based on exception model POWERPC_EXCP_BOOKE. - Not supporting ppc440 Bharat Bhushan (5): ppc: debug stub: Get trap instruction opcode from KVM ppc: Add interface to inject interrupt to guest ppc: Add debug interrupt injection handler ppc: Add software breakpoint support ppc: Add hw breakpoint watchpoint support target-ppc/kvm.c | 384 +++++++++++++++++++++++++++++++++++++++++++++++++++---- 1 file changed, 356 insertions(+), 28 deletions(-) -- 1.9.0
