  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

----------------------------------------------------------------

      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

      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

I see that Akihiko has asked for this not to be merged, so I'll
drop this pull req.

Akihiko: for the future, if you want an on-list pullreq
to not be merged, please reply to the cover letter, not to
an individual patch. I am very unlikely to notice replies
to individual patches before I do a merge. (I only noticed
in this case because somebody happened to point it out to
me on IRC.)

thanks
