Two new feature flags were added to control whether upcalls to the transport result in context switches or stay in the calling context. NVMET_FCTGTFEAT_CMD_IN_ISR: By default, if the flag is not set, the transport assumes the lldd is in a non-isr context and in the cpu context it should be for the io queue. As such, the cmd handler is called directly in the calling context. If the flag is set, indicating the upcall is an isr context, the transport mandates a transition to a workqueue. The workqueue assigned to the queue is used for the context. NVMET_FCTGTFEAT_OPDONE_IN_ISR By default, if the flag is not set, the transport assumes the lldd is in a non-isr context and in the cpu context it should be for the io queue. As such, the fcp operation done callback is called directly in the calling context. If the flag is set, indicating the upcall is an isr context, the transport mandates a transition to a workqueue. The workqueue assigned to the queue is used for the context. Updated lpfc for flags Signed-off-by: James Smart <james.smart@broadcom.com> Signed-off-by: Sagi Grimberg <sagi@grimberg.me> |
