Subject: [PATCH V2 11/23] xen/ioreq: Move x86's io_completion/io_req fields to struct vcpu
Date: Thu, 15 Oct 2020 19:44:22 +0300 [thread overview]
Message-ID: <1602780274-29141-12-git-send-email-olekstysh@gmail.com> (raw)
In-Reply-To: <1602780274-29141-1-git-send-email-olekstysh@gmail.com>
From: Oleksandr Tyshchenko <oleksandr_tyshchenko@epam.com>
The IOREQ is a common feature now and these fields will be used
on Arm as is. Move them to common struct vcpu as a part of new
struct vcpu_io. Also move enum hvm_io_completion to xen/sched.h
and remove "hvm" prefixes.
This patch completely removes layering violation in the common code.

Please note, this is a split/cleanup/hardening of Julien's PoC:
"Add support for Guest IO forwarding to a device emulator"
***
I was thinking that it may be better to place these two fields
into struct vcpu directly (without intermediate "io" struct).
I think, this way the code which operates with these fields
would become cleaner. Another possible option would be either
to rename "io" struct (I failed to think of a better name) or
to drop(replace?) duplicating "io" prefixes from these fields.
***
Changes V1 -> V2:
- new patch
