[PATCH v2 00/13] TYPE_SERIAL cleanup

Posted by Bernhard Beschow 1 month, 1 week ago

This series consists of cosmetic changes around TYPE_SERIAL. The biggest change
is having it derive from TYPE_SYS_BUS_DEVICE which 1) eliminates usage of
qemu_{un,}register_reset() and 2) stops all its users from accessing private
data. The latter allows TYPE_SERIAL to be ported to Rust in the (near) future.

v2:
* Pick up R-b tags. Thanks!
* Ad patch to free consumers of TYPE_SERIAL from setting up MemoryRegionOps;
  configure via properties instead which should resolve odd code (Peter)
* Improve wording in one commit message (Peter)
* Sort patches by moving char/serial last
-> Keep "Avoid implicit conversion when tracing" untouched for now. Can be
  omitted if deemed inappropriate.

Testing done:
* Make check
* Boot mpc8544ds machine with Linux and interact with it on the serial console
* Boot q35 machine with Arch Linux and interact with it on the serial console

Bernhard Beschow (13):
  hw/arm/Kconfig: Fix serial selection for NPCM8XX
  hw/arm/aspeed_ast27x0-{ssp, tsp}: Do not access SerialMM internals
    directly
  util/fifo8: Make all read-only methods const-correct
  hw/char/serial: Remove explicit cast from void pointer
  hw/char/serial: Prefer fifo8 methods over open-coding
  hw/char/serial: Reuse fifo8_num_used()
  hw/char/serial: Remove stale comment
  hw/char/serial: Add constants for Line Control Register
  hw/char/serial: Remove redundant reset
  hw/char/serial: Avoid implicit conversion when tracing
  hw/char/serial: Keep MemoryRegionOps private
  hw/char/serial: Inherit from SysBusDevice
  hw/char/serial: Plug into reset framework
