[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH V2 06/23] xen/ioreq: Make x86's hvm_ioreq_(page/vcpu/server) structs common
From: Oleksandr Tyshchenko <oleksandr_tyshchenko@xxxxxxxx>
The IOREQ is a common feature now and these structs will be used
on Arm as is. Move them to xen/ioreq.h and remove "hvm" prefixes.
Signed-off-by: Oleksandr Tyshchenko <oleksandr_tyshchenko@xxxxxxxx>
CC: Julien Grall <julien.grall@xxxxxxx>
---
Please note, this is a split/cleanup/hardening of Julien's PoC:
"Add support for Guest IO forwarding to a device emulator"
Changes RFC -> V1:
- new patch
Changes V1 -> V2:
- remove "hvm" prefix
