[PATCH v4 09/13] accel/all: Extract common_vcpu_thread_create() |
Date: |
Wed, 23 Mar 2022 18:17:47 +0100 |
From: Philippe Mathieu-Daudé <f4bug@amsat.org>
All accelerators implement a very similar create_vcpu_thread()
handler. Extract the common part as common_vcpu_thread_create(),
which only requires the AccelOpsClass::vcpu_thread_fn() routine
and the accelerator AccelOpsClass::thread_name for debugging
purpose.
The single exception is TCG/RR which re-use a single vCPU. Have
it use the same logic by using the .precheck/.postcheck handlers.
Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org>
