[PATCH v3 00/29] hw,target: Prefer fast cpu_env() over slower CPU QOM cast macro

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Patches missing review: 1, 2, 5, 6, 8, 11, 14, 15, 29

It will be simpler if I get the whole series via my hw-cpus
tree once fully reviewed.

Since v2:
- Rebased
- bsd/linux-user
- Preliminary clean cpu_reset_hold
- Add R-b

Since v1:
- Avoid CPU() cast (Paolo)
- Split per targets (Thomas)

Use cpu_env() -- which is fast path -- when possible.
Bulk conversion using Coccinelle spatch (script included).

Philippe Mathieu-Daudé (29):
  bulk: Access existing variables initialized to &S->F when available
  hw/core: Declare CPUArchId::cpu as CPUState instead of Object
  hw/acpi/cpu: Use CPUState typedef
  bulk: Call in place single use cpu_env()
  scripts/coccinelle: Add cpu_env.cocci script
  target: Replace CPU_GET_CLASS(cpu -> obj) in cpu_reset_hold() handler
