[PATCH 0/3] accel: Factor tcg_cpu_reset_hold() out of cpu-common.c

Posted by Philippe Mathieu-Daudé 7 months, 2 weeks ago

Hi,

We want to have exec/ code agnostic to accelerators.
still we use various call to TCG and KVM. This series
factor the TCG code from cpu_common_reset_hold() to an
accel-specific handler within AccelOpsClass.

Based-on: <20230915190009.68404-1-philmd@linaro.org>

Philippe Mathieu-Daudé (3):
  accel/tcg: Declare tcg_flush_jmp_cache() in 'exec/tb-flush.h'
  accel: Introduce cpu_exec_reset_hold()
  accel/tcg: Factor tcg_cpu_reset_hold() out
