I'm actually working on a scheme to provide support to handle PCI errors related to assigned devices. The goal is to notify the coresponding driver so that all his I/O access are stop quickly and to provide that same driver a chance to get back in sync with the device. I'm just wondering how can I make use of your aer support in Q35? As you already know, error detection and error recovery phases are driven by a state machine where the next state depends on the returned value from the current callback. Also only the host can performed the link recovery sequence for assigned devices. Because of such it seems like the only way to maintain consistency between the assigned device and it's corresponding driver is to perform the error detection/recovery phase in lockstep with the host? thanks, -Etienne
