Josef Söntgen b51ae104c2 qemu-usb: use bounce buffer to access DMA memory ... The former implemention assumed that the guest physical memory is mapped continously. This, however, is not true. Writing larger files to an USB stick with a Windows 10 guest would therefore lead to data corruption. The current implementation uses a bounce buffer to copy the data to and from the guest physical memory and leaves dealing with the memory mappings entirely up to the VMM. Fixes #4017.		2021-02-23 12:02:44 +01:00
