This is the following patch after removing pending_pre_work, it make sure all io emulation is done on its own cpu. For hv emulated request, it follows the steps: hv_emulate_pio->emulate_pio_complete hv_emulate_mmio->emulate_mmio_complete For dm emulated request, it follows the steps: acrn_insert_request->dm_emulate_io_complete while in acrn_insert_request, it could trigger scheduling out then resume by hcall_notify_ioreq_finish, or busy wait for ioreq completion if polling mode is enabled.
