  docs/devel: document some plugin assumptions (2024-01-16 10:34:20 +0000)

----------------------------------------------------------------
read-only register access for plugins:

  - move misa_mxl to CPU class for riscv
  - use GDBFeature for arm XML
  - use GDBFeature for ppc XML
  - use GDBFeature for riscv XML
  - unify gdb code to use GDBFeature
  - move dynamic XML generation to core GDB code
  - provide introspection APIs for rest of QEMU
  - expose a plugin API to access registers
  - fix memory re-use in execlog
  - extend execlog to track registers
  - optimise instrumentation based on disassembly
  - tweak API docs and expand on assumptions

----------------------------------------------------------------
Akihiko Odaki (15):
      hw/riscv: Use misa_mxl instead of misa_mxl_max
      target/riscv: Remove misa_mxl validation
      target/riscv: Move misa_mxl_max to class
      target/riscv: Validate misa_mxl_max only once
      target/arm: Use GDBFeature for dynamic XML
      target/ppc: Use GDBFeature for dynamic XML
      target/riscv: Use GDBFeature for dynamic XML
      gdbstub: Use GDBFeature for gdb_register_coprocessor
      gdbstub: Use GDBFeature for GDBRegisterState
      gdbstub: Change gdb_get_reg_cb and gdb_set_reg_cb
      gdbstub: Simplify XML lookup
      gdbstub: Infer number of core registers from XML
      hw/core/cpu: Remove gdb_get_dynamic_xml member
      gdbstub: Add members to identify registers to GDBFeature
      plugins: Use different helpers when reading registers

Alex Bennée (7):
      gdbstub: expose api to find registers
      plugins: add an API to read registers
      contrib/plugins: fix imatch
      contrib/plugins: extend execlog to track register changes
      contrib/plugins: optimise the register value tracking
      docs/devel: lift example and plugin API sections up
      docs/devel: document some plugin assumptions
