[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v4 00/19] Introducing Xen PV block driver to OVMF
Hi all,
This patch series is implementing the necessary in order to access a PV block
device. For that, one need a XenStore client, a XenBus client, and the PV block
driver.
There are two new drivers, XenbusDxe and XenPvBlkDxe. The first one implement a
bus drivers, and the second is a block drivers.
The GUID for the drivers XenBusDxe and XenPvBlkDxe and for the protocol XenBus
have been genereted using the UefiDriverWizard.
* Change in V4:
- new file OvmfPkg/Include/IndustryStandard/Xen/README in the patch "OvmfPkg:
Add public headers from Xen Project." which is mostly a copy/past of the
patch description.
- Added a brief description for both driver in the .inf file.
- And replaced the BSD-2 license text in file headers by the commonly used file
header text.
* Change in V3:
- 32bit support:
It's done by adding a few #ifdef __i386__; #pragma pack(4); when necessary in
the Xen headers. More detail about this in the description of the patch
"OvmfPkg: Add public headers from Xen Project".
- Licenses:
The MIT licence is added to the OvmfPkg/Licence.txt file, with a mentions of
which directories might use them. This is the first patch, "OvmfPkg: Add the
MIT license to License.txt".
Other changes have been listed after a '---' line in every patches.
