[Qemu-devel] [PATCH v11 00/20] gdbstub: Refactor command packets handler

[Jon Doron <arilou@gmail.com>]

This patch series refactors the old gdbstub command packets handler
with a new infrastructure which should ease extending and adding new
and missing gdb command packets.

version 11 changes:
- Add reviewed by tag
- Requires review:
  gdbstub: Implement deatch (D pkt) with new infra
  gdbstub: Implement breakpoint commands (Z/z pkt) with new infra
  gdbstub: Implement set register (P pkt) with new infra
  gdbstub: Implement get register (p pkt) with new infra
  gdbstub: Implement file io (F pkt) with new infra
  gdbstub: Implement v commands with new infra
  gdbstub: Implement generic set/query (Q/q pkt) with new infra
  gdbstub: Implement target halted (? pkt) with new infra
  gdbstub: Implement qemu physical memory mode
- Already reviewed:
  gdbstub: Add infrastructure to parse cmd packets
  gdbstub: Implement thread_alive (T pkt) with new infra
  gdbstub: Implement continue (c pkt) with new infra
  gdbstub: Implement continue with signal (C pkt) with new infra
  gdbstub: Implement set_thread (H pkt) with new infra
  gdbstub: Implement write memory (M pkt) with new infra
  gdbstub: Implement read memory (m pkt) with new infra
  gdbstub: Implement write all registers (G pkt) with new infra
  gdbstub: Implement read all registers (g pkt) with new infra
  gdbstub: Implement step (s pkt) with new infra
  gdbstub: Clear unused variables in gdb_handle_packet

version 10 changes:
- Remove kvm added API as this is not really required and can be
  accomplished by defining a coprocessor callback with a system
  specific xml (see: 200bf5b7ffea635079cc05fdfb363372b9544ce7)
- Remove the new QEMU extended commands to read KVM MSRs
- Various fixes from Code Review by Alex Bennee
- Change the QEMU specific command to read physical memory to non-User QEMU 
- Per patch changes:
  gdbstub: Add infrastructure to parse cmd packets
    * remove the union for the flags in GdbCmdParseEntry
  gdbstub: Implement deatch (D pkt) with new infra
    * Changed default handling for error flow / command not found
  gdbstub: Implement continue with signal (C pkt) with new infra
    * Added comment we dont support C sig;[addr] commands
  gdbstub: Implement set_thread (H pkt) with new infra
    * Change num_params check to be equal and not less than
  gdbstub: Implement breakpoint commands (Z/z pkt) with new infra
    * Merged z/Z commands into a single patch
  gdbstub: Implement read memory (m pkt) with new infra
    * Change num_params check to be equal and not less than
  gdbstub: Implement file io (F pkt) with new infra
    * Changed to have a single command parser
  gdbstub: Implement generic set/query (Q/q pkt) with new infra
    * Merged q/Q and qemu.Supported patches into a single patch
  gdbstub: Implement target halted (? pkt) with new infra
    * Removed TODO comment and added a note about it in the commit msg
  gdbstub: Implement qemu physical memory mode
    * Added CONFIG_USER_ONLY where required

version 9 changes:
- checkpatch fixes

version 8 changes:
- Add new command to display the Supported qemu generic query/sets
- kvm: Add API to read/write a MSR
- Add new commands specific for qemu:
  * Command to swap the memory GDB sees to be the physical memory
  * Commands to read and write a MSR

version 7 changes:
- Fixed few checkpatch complaints
- Feedback from Alex Bennee

version 4-6 changes:
- mostly feedback from Richard Henderson

version 3 changes
- Split the single patch to many individual patches for easier reviewing

version 2 changes
- Code convention fixes
