* Use gcc warning flag -Wnested-externsBlue Swirl2010-09-181-0/+3
| | | | | | | | | If the compiler supports the warning flag -Wnested-externs, use it. Avoid the only warning by moving the declaration of xml_builtin to a more proper place. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

* Guest debugging support for KVM (Jan Kiszka)aliguori2009-03-121-0/+7
| | | | | | | | | | | | | | | | | | | | | | | This is a backport of the guest debugging support for the KVM accelerator that is now part of the KVM tree. It implements the reworked KVM kernel API for guest debugging (KVM_CAP_SET_GUEST_DEBUG) which is not yet part of any mainline kernel but will probably be 2.6.30 stuff. So far supported is x86, but PPC is expected to catch up soon. Core features are: - unlimited soft-breakpoints via code patching - hardware-assisted x86 breakpoints and watchpoints Changes in this version: - use generic hook cpu_synchronize_state to transfer registers between user space and kvm - push kvm_sw_breakpoints into KVMState Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6825 c046a42c-6fe2-441c-8c8c-71466251a162
* User-mode GDB stub improvements - handle signalsaurel322008-12-181-0/+2
| | | | | | | | | | | | | Handle signals in the user-mode GDB stub. Report them to GDB, and allow it to change or cancel them. Also correct the protocol numbering; it happens to match Linux numbering for SIGINT and SIGTRAP, but that's just good fortune.

| | | | | | | | | | Close gdbserver in child processes, so that only one stub tries to talk to GDB at a time. Updated from an earlier patch by Paul Brook.

* gdbstub: manage CPUs as threads (Jan Kiszka)aliguori2008-11-181-0/+1
| | | | | | | | | | | | | | | | | | | | This patch enhances QEMU's built-in debugger for SMP guest debugging. Using the thread support of the gdb remote protocol, each VCPU is mapped on a pseudo thread and exposed to the gdb frontend. This way you can easy switch the focus of gdb between the VCPUs and observe their states. On breakpoint hit, the focus is automatically adjusted just as for normal multi-threaded application under gdb control. Furthermore, the patch propagates breakpoint and watchpoint insertions or removals to all CPUs, not just the current one as it was the case so far. Without this, SMP guest debugging was practically unfeasible.
