* vga optimization (Glauber Costa)aliguori2008-11-241-0/+2
| | | | | | | | | | | | | | | | | | | | | Hypervisors like KVM perform badly while doing mmio on a loop, because it'll generate an exit on each access. This is the case with VGA, which results in very bad performance. In this patch, we map the linear frame buffer as RAM, make sure it has dirty region tracking enabled, and then just let the region to be written.

* Introduce BP_CPU as a breakpoint type (Jan Kiszka)aliguori2008-11-181-0/+1
| | | | | | | | | | | | | | | | | Add another breakpoint/watchpoint type to BP_GDB: BP_CPU. This type is intended for hardware-assisted break/watchpoint emulations like the x86 architecture requires. To keep the highest priority for BP_GDB breakpoints, this type is always inserted at the head of break/watchpoint lists, thus is found first when looking up the origin of a debug interruption.

* Introduce BP_WATCHPOINT_HIT flag (Jan Kiszka)aliguori2008-11-181-0/+1
| | | | | | | | | | | | | When one watchpoint is hit, others might have triggered as well. To support users of the watchpoint API which need to detect such cases, the BP_WATCHPOINT_HIT flag is introduced and maintained.

* Restore pc on watchpoint hits (Jan Kiszka)aliguori2008-11-181-0/+1
| | | | | | | | | | | | | | | In order to provide accurate information about the triggering instruction, this patch adds the required bits to restore the pc if the access happened inside a TB. With the BP_STOP_BEFORE_ACCESS flag, the watchpoint user can control if the debug trap should be issued on or after the accessing instruction.

* Refactor and enhance break/watchpoint API (Jan Kiszka)aliguori2008-11-181-6/+17
| | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | The IO index is now stored in its own field, instead of being wedged into the vaddr field. This eliminates the ROMD and watchpoint host pointer weirdness. The IO index space is expanded by 1 bit, and several additional bits are made available in the TLB vaddr field. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@4704 c046a42c-6fe2-441c-8c8c-71466251a162

* Add support for the 'k' (kill) and 'D' (detach) packets (Jason Wessel).edgar_igl2008-05-171-0/+2
| | | | | | | | | | | | | | | | | | | | 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

* Use float32/64 instead of float/doubleaurel322008-03-131-0/+5
| | | | | | | | | | | | | | The patch below uses the float32 and float64 types instead of the float and double types in the PPC code. This doesn't change anything when using softfloat-native as the types are the same, but that helps compiling the PPC target with softfloat. It also defines a new union CPU_FloatU in addition to CPU_DoubleU, and use them instead of identical unions that are defined in numerous places. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@4047 c046a42c-6fe2-441c-8c8c-71466251a162
