This is the code that will do the actual communication between OVMF and
a PV block backend, where the block device lives. The protocol used is
describe in the blkif.h header.
This implementation originally comes from Mini-OS, a part of the Xen
Project.
Change in V4:
- add file header to BlockFront.h (license, copyright, brief desc)
Change in V3:
- Improve comment of XenBusReadUint64.
- Moving blkif.h to this patch
with the necessary #pragma pack(4) applied for Ia32.
- Add a note about the license in the commit message
- Add "The protocol used is describe in the blkif.h header." in the
commit message
- Have a mandatory sector-size multiple of 512 or fail to initialize.
- use Sector instead of Offset for IO request.
with Sector been 512-byte unit.
- print something if EventChannelNotify return an error.
Change in V2:
- trigger CoW is probably not needed on OVMF (as opposed to Mini-OS),
removed the test.
- comments
- renamed XenbusReadInteger to XenBusReadUint64
- remove callback from IoData, use simple status instead
- return a status from the synchronus io

This patch imports publics headers in order to use features from Xen
like XenStore, PV Block... There is only the necessary header files and
there are only a few modifications in order to facilitate future merge of
more recent header (that would be necessary to access new features).
There is little modification compared to the original files:
- Removed most of the unused part of the headers
- Use of ZeroMem() instead of memset()
- using #pragma pack(4) for IA32 compilation.
- Replace types to be more UEFI compliant using a script.
OVMF, when built for IA32 arch, uses the gcc switch -malign-double. This
change the alignment of fields in some struct compare to what is
espected by Xen and any backends. To fix the alignment, the #pragma pack(4)
directive is used around the struct that need it.
Command to run to change types:
find OvmfPkg/Include/IndustryStandard/Xen -type f -name '*.h' -exec sed
--regexp-extended --file=fix_type_in_xen_includes.sed --in-place {} \;
Avoid changing the 'long' that is not a type (with the first line).

Keep track of the hardware settings in the "ReceiveFilterSetting" field of
the EFI_SIMPLE_NETWORK_MODE structure.
From now, after initialization, all filters are disabled and thus no packet
received.

Fix return codes in case of errors.
Fix translation from EFI open mode to semi-hosting open mode to avoid the
truncate to zero length of an already existing file opened in read/write
or read/write/create mode.

Add or fix checking of the input parameters of the functions that constitute
the EFI_SIMPLE_NETWORK_PROTOCOL interface provided by the LAN9118 driver.
In case of invalid calls, the returned error codes are now compliant with the
UEFI specificationi and the SCT tests checking for those error codes do not
fail anymore.

Change mnemonic SEMIHOST_FILE_MODE_CREATE with mnemonic SEMIHOST_FILE_MODE_UPDATE.
The bit referred to by this mnemonic is for the semi-hosting open mode code the
equivalent of the + in the ISO C fopen mode terminology. This allows to select the
so called update mode for which both read and write are allowed on the open file.
The mnemonic SEMIHOST_FILE_MODE_UPDATE is more in line with the ISO C fopen mode
terminology. A description of the ISO C fopen modes can be found here :

This function returns the revision of the GIC Architecture.
Some GICv3 controllers can work in GICv2 mode. Switching to an
older GIC revision is driven by the higher level exception level.
This function allows code to support any GIC revision at runtime.
