[Qemu-devel] [PATCH 1/2] hyperv: add header with protocol definitions |
|
Date: |
Thu, 13 Jul 2017 23:15:21 +0300 |
The definitions for Hyper-V emulation are currently taken from a header
imported from the Linux kernel.
However, as these describe a third-party protocol rather than a kernel
API, it probably wasn't a good idea to publish it in the kernel uapi.
This patch introduces a header that provides all the necessary
definitions, superseding the one coming from the kernel.
The new header supports (temporary) coexistence with the kernel one.
The constants explicitly named in the Hyper-V specification (e.g. msr
numbers) are defined in a non-conflicting way. Other constants and
types have got new names.
While at this, the protocol data structures are defined in a more
conventional way, without bitfields, enums, and excessive unions.
The code using this stuff is adjusted, too; it can now be built both
with and without the kernel header in the tree.
