Igor Druzhinin 84201604c7 xen/pt: use address_space_memory object for memory region hooks ... Commit 99605175c (xen-pt: Fix PCI devices re-attach failed) introduced a subtle bug. As soon as the guest switches off Bus Mastering on the device it immediately causes all the BARs be unmapped due to the DMA address space of the device being changed. This is undesired behavior because the guest may try to communicate with the device after that which triggers the following errors in the logs: [00:05.0] xen_pt_bar_read: Error: Should not read BAR through QEMU. @0x0000000000000200 [00:05.0] xen_pt_bar_write: Error: Should not write BAR through QEMU. @0x0000000000000200 The issue that the original patch tried to workaround (uneven number of region_add/del calls on device attach/detach) was fixed in d25836cafd (memory: do explicit cleanup when remove listeners).
