2008-12-18User-mode GDB stub improvements - handle signalsaurel32
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.

2008-11-18gdbstub: manage CPUs as threads (Jan Kiszka)aliguori
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.

2008-11-18Refactor and enhance break/watchpoint API (Jan Kiszka)aliguori
This patch prepares the QEMU cpu_watchpoint/breakpoint API to allow the succeeding enhancements this series comes with. First of all, it overcomes MAX_BREAKPOINTS/MAX_WATCHPOINTS by switching to dynamically allocated data structures that are kept in linked lists. This also allows to return a stable reference to the related objects, required for later introduced x86 debug register support. Breakpoints and watchpoints are stored with their full information set and an additional flag field that makes them easily extensible for use beyond pure guest debugging.

2008-10-31Implement "info chardev" command. (Gerd Hoffmann)aliguori
This patch makes qemu keep track of the character devices in use and implements a "info chardev" monitor command to print a list. qemu_chr_open() sticks the devices into a linked list now. It got a new argument (label), so there is a name for each device. It also assigns a filename to each character device. By default it just copyes the filename passed in. Individual drivers can fill in something else though. qemu_chr_open_pty() sets the filename to name of the pseudo tty allocated. Output looks like this: (qemu) info chardev monitor: filename=unix:/tmp/run.sh-26827/monitor,server,nowait serial0: filename=unix:/tmp/run.sh-26827/console,server serial1: filename=pty:/dev/pts/5 parallel0: filename=vc:640x480 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5575 c046a42c-6fe2-441c-8c8c-71466251a162

2008-05-17Add support for the 'k' (kill) and 'D' (detach) packets (Jason Wessel).edgar_igl
Implement the 'k' gdbserial packet which kills the qemu instance via the debugger stub. Implement the 'D' detach packet for the gdb stub such that you can disconnect gdb with the "detach" command. This required implementing a cpu_breakpoint_remove_all() and a cpu_watchpoint_remove_all() function to cleanup all the breakpoints and watchpoints prior to leaving the gdb stub else simulation can stop with no debugger attached. On a '?' packet remove all the breakpoints and watchpoints. This is considered more of a safety net in case you force killed gdb or it crashed and you are reconnecting. The identical behavior exists for kgdb in the linux kernel. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@4478 c046a42c-6fe2-441c-8c8c-71466251a162
