The IP driver uses EfiCreateProtocolNotifyEvent() to register notify callback
function for IpSec protocol, but it didn't notice that the callback will always
be executed at least once, even the protocol wasn't in handle database.
As a result, the Ip6IpSecProcessPacket() will still always call LocateProtocol()
even the IpSec protocol is not installed, which will impact the network
performance.

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=620
Adds the support for SD/eMMC device path to show as a boot option.
The CID register content (returned from DiskInfo->Inquiry) seems do not
provide very useful/readable 'OEM/Application ID' and 'Product name'
field.
For SD devices, the OID is a 2-character ASCII string and the Product name
is a 5-character ASCII string.
For eMMC devices, the OID is an 8-bit binary number and the Product name
is a 6-character ASCII string.
These strings are relatively short and do not provide a very readable
description. Hence, this commit uses general 'SD (eMMC) Device' for the
boot option description.

VirtioGpuDxe is now IOMMU-clean; it translates system memory addresses to
bus master device addresses. Negotiate VIRTIO_F_IOMMU_PLATFORM in parallel
with VIRTIO_F_VERSION_1. (Note: the VirtIo GPU device, and this driver,
are virtio-1.0 only (a.k.a. "modern-only").)

VirtioGpuDxe is a UEFI Bus driver (not a Device driver). This is because a
UEFI graphics driver is expected to produce its GraphicsOutput protocol
instance(s) on new child handle(s) of the video controller handle, one
child handle (plus GOP) per video output (or, one child handle plus GOP
per combination of multiple video outputs).
In VirtioGpuDxe, we support a single VirtIo GPU head (scanout), namely
head#0. This means that, with regard to a specific VirtIo GPU device, the
driver may be in one of three states, at any time:
[1] VirtioGpuDxe has not bound the device at all,
[2] VirtioGpuDxe has bound the device, but not produced the sole child
handle for head#0,
[3] VirtioGpuDxe has bound the device, and produced the sole child handle
for head#0, with a GOP instance on the child handle.
(Which state the driver is in wrt. a given VirtIo GPU device depends on
the VirtioGpuDriverBindingStart() / VirtioGpuDriverBindingStop()
invocations issued by the ConnectController() / DisconnectController()
boot services. In turn those come from BDS or e.g. the UEFI shell.)
The concept of "current video mode" is technically tied to the GOP (i.e.,
the child handle, state [3] only), not the VirtIo GPU controller handle.
This is why we manage the storage that backs the current video mode in our
EFI_GRAPHICS_OUTPUT_PROTOCOL.SetMode() member implementation.
GopSetMode() is first called *internally*, when we enter state [3] (that
is, when we produce the child handle + GOP on it):
VirtioGpuDriverBindingStart() [DriverBinding.c]
InitVgpuGop() [DriverBinding.c]
VgpuGop->Gop.SetMode() [Gop.c]
When this happens, we allocate the backing store *without* having a
preexistent backing store (due to no preexistent video mode and GOP).
Skipping VirtIo GPU details not relevant for this patch, we just note that
the backing store is exposed *permanently* to the VirtIo GPU device, with
the RESOURCE_ATTACH_BACKING command.
When external clients call the EFI_GRAPHICS_OUTPUT_PROTOCOL.Blt() member
function -- called GopBlt() in this driver --, in state [3], the function
operates on the backing store, and sends only small messages to the VirtIo
GPU device.
When external clients call GopSetMode() for switching between video modes
-- in state [3] --, then
- a new backing store is allocated and exposed to the device (attached to
a new host-side VirtIo GPU resource),
- head#0 is flipped to the new backing store,
- on success, the ReleaseGopResources() function both detaches the
previous backing store from the VirtIo GPU device, an releases it. The
new backing store address and size are saved in our GOP object. (In
other words, we "commit" to the new video mode.)
When the DisconnectController() boot service asks us to leave state [3] --
we can leave it directly only for state [2] --, then the
ReleaseGopResources() function is called on a different path:
VirtioGpuDriverBindingStop() [DriverBinding.c]
UninitVgpuGop() [DriverBinding.c]
ReleaseGopResources() [Gop.c]
In this case, the backing store being released is still in use (we're not
leaving it for a new mode -- head#0 has not been flipped "away" from it),
so in ReleaseGopResources() we disable head#0 first.
(The ReleaseGopResources() function is called the same way on the error
path in InitVgpuGop(), if the first -- internal -- VgpuGop->Gop.SetMode()
call succeeds, but the rest of InitVgpuGop() fails.)
Based on the above, for IOMMU-compatibility,
- in GopSetMode(), don't just allocate, but also map the backing store of
the nascent video mode to a device address, for bus master common buffer
operation,
- (the VirtioGpuAllocateZeroAndMapBackingStore() helper function
introduced in the last patch takes care of zeroing internally,)
- pass the device address to the VirtIo GPU device in the
RESOURCE_ATTACH_BACKING command,
- if GopSetMode() succeeds, save the mapping token,
- if GopSetMode() fails, don't just free but also unmap the still-born
backing store,
- in ReleaseGopResources(), don't just free but also unmap the backing
store -- which is the previous backing store if we're mode-switching,
and the current backing store if we're leaving state [3].
Finally, ExitBootServices() may be called when the driver is in either
state [1], [2] or [3], wrt. a given VirtIo GPU device. (Of course we are
only notified in states [2] and [3].) If we get the notification in state
[3], then the current video mode's backing store has to be unmapped, but
not released. (We must not change the UEFI memory map.)

Introduce the VirtioGpuAllocateZeroAndMapBackingStore() and
VirtioGpuUnmapAndFreeBackingStore() helper functions. These functions tie
together the allocation, zeroing and mapping, and unmapping and
deallocation, respectively, of memory that the virtio GPU will permanently
reference after receiving the RESOURCE_ATTACH_BACKING command.
With these functions we can keep the next patch simpler -- the GOP
implementation in "Gop.c" retains its error handling structure, and
remains oblivious to VIRTIO_DEVICE_PROTOCOL and VirtioLib.

The RESOURCE_ATTACH_BACKING virtio GPU command assigns guest-side backing
pages to a host-side resource that was created earlier with the
RESOURCE_CREATE_2D command.
We compose the RESOURCE_ATTACH_BACKING command in the
VirtioGpuResourceAttachBacking() function. Currently this function takes
the parameter
IN VOID *FirstBackingPage
This is only appropriate as long as we pass a (guest-phys) system memory
address to the device. In preparation for a mapped bus master device
address, change the above parameter to
IN EFI_PHYSICAL_ADDRESS BackingStoreDeviceAddress
In order to keep the current call site functional, move the (VOID*) to
(UINTN) conversion out of the function, to the call site.
The "Request.Entry.Addr" field already has type UINT64.
This patch is similar to commit 4b725858de68 ("OvmfPkg/VirtioLib: change
the parameter of VirtioAppendDesc() to UINT64", 2017-08-23).

Every virtio GPU command used by VirtioGpuDxe is synchronous and formatted
as a two-descriptor chain: request, response. The internal workhorse
function that all the command-specific functions call for such messaging
is VirtioGpuSendCommand().
In VirtioGpuSendCommand(), map the request from system memory to bus
master device address for BusMasterRead operation, and map the response
from system memory to bus master device address for BusMasterWrite
operation.
Pass the bus master device addresses to VirtioAppendDesc(). (See also
commit 4b725858de68, "OvmfPkg/VirtioLib: change the parameter of
VirtioAppendDesc() to UINT64", 2017-08-23.)

VirtioGpuDxe uses one virtio ring, for VIRTIO_GPU_CONTROL_QUEUE.
Map it for bus master common buffer operation with VirtioRingMap(), so
that it can be accessed equally by both guest and hypervisor even if an
IOMMU is used. (VirtioRingInit() already allocates the ring suitably for
this, see commit b0338c53297c, "OvmfPkg/VirtioLib: alloc VRING buffer with
AllocateSharedPages()", 2017-08-23).
Pass the resultant translation offset ("RingBaseShift"), from system
memory address to bus master device address, to VIRTIO_SET_QUEUE_ADDRESS.
Unmap the ring in all contexts where the ring becomes unused (these
contexts are mutually exclusive):
- in VirtioGpuInit(): the ring has been mapped, but we cannot complete the
virtio initialization for another reason,
- in VirtioGpuUninit(): the virtio initialization has succeeded, but
VirtioGpuDriverBindingStart() fails for another reason, or
VirtioGpuDriverBindingStop() unbinds the device after use,
- in VirtioGpuExitBoot(): ExitBootServices() is called after
VirtioGpuDriverBindingStart() has successfully bound the device.
(Unmapping the ring does not change the UEFI memory map.)

VirtioScsiDxe driver has been updated to use IOMMU-like member functions
from VIRTIO_DEVICE_PROTOCOL to translate the system physical address to
device address. We do not need to do anything special when
VIRTIO_F_IOMMU_PLATFORM bit is present hence treat it in parallel with
VIRTIO_F_VERSION_1.

When device is behind the IOMMU, driver is require to pass the device
address of virtio request, response and any memory referenced by those
request/response to the bus master.
The patch uses IOMMU-like member functions from VIRTIO_DEVICE_PROTOCOL to
map request and response buffers system physical address to the device
address.
- If the buffer need to be accessed by both the processor and a bus
master then map with BusMasterCommonBuffer.
- If the buffer need to be accessed for a write operation by a bus master
then map with BusMasterWrite.
However, after a BusMasterWrite Unmap() failure, error reporting via
EFI_EXT_SCSI_PASS_THRU_SCSI_REQUEST_PACKET would be very complex,
therefore we map such buffers too with BusMasterCommonBuffer.
- If the buffer need to be accessed for a read operation by a bus master
then map with BusMasterRead.

When virtio request fails we return EFI_DEVICE_ERROR, as per the spec
EFI_EXT_SCSI_PASS_THRU_PROTOCOL.PassThru() member function is required
to implement elaborated error reporting.
The patch refactors out entire block of the code that creates the host
adapter error into a separate helper function (ReportHostAdapterError).

When device is behind the IOMMU then driver need to pass the device
address when programing the bus master. The patch uses VirtioRingMap() to
map the VRING system physical address to device address.

Now that ArmDmaLib can take care of its own memory allocation needs,
let's get rid of UncachedMemoryAllocationLib entirely. This forces
platforms to declare the required semantics (non-cache coherent DMA,
whichever way it is implemented), rather than using uncached memory
allocations directly, which may not always be the right choice, and
prevents sharing of drivers between platforms if one is cache coherent
and the other is not.

While modern AARCH64 server systems use ACPI for describing the platform
topology to the OS, ARM systems and AARCH64 outside of the server space
mostly use device tree binaries, which are compiled from device tree
source files using the device tree compiler.
Currently, such source files and binaries may be kept in the EDK2 platform
trees, but are not integrated with the build, which means they need to be
kept in sync and recompiled manually, which is cumbersome.
So let's wire up BaseTools support for them: add tool definitions for the
DTC compiler and preprocessor flags that allow these source files to use
FixedPcd expressions and other macros defined by AutoGen.h
This way, a device tree binary can be built from source and emitted into
a FFS file automatically using something like:
DeviceTree.inf:
[Defines]
INF_VERSION = 0x00010019
BASE_NAME = SomePlatformDeviceTree
FILE_GUID = 25462CDA-221F-47DF-AC1D-259CFAA4E326 # gDtPlatformDefaultDtbFileGuid
MODULE_TYPE = USER_DEFINED
VERSION_STRING = 1.0
[Sources]
SomePlatform.dts
[Packages]
MdePkg/MdePkg.dec
SomePlatform.fdf:
INF RuleOverride = DTB xxx/yyy/DeviceTree.inf
[Rule.Common.USER_DEFINED.DTB]
FILE FREEFORM = $(NAMED_GUID) {
RAW BIN |.dtb
}
where it can be picked at runtime by the DTB loader that may refer to it
using gDtPlatformDefaultDtbFileGuid.
Note that this is very similar to how ACPI tables may be emitted into a
FFS file with a known GUID and picked up by AcpiTableDxe at runtime.
