define PRINT_BIT_FIELD(Variable, FieldName) \ Print (L"%5a%42a: %x\n", #Variable, #FieldName, \ ##Variable.Bits.##FieldName); The above definition in UefiCpuPkg/Application/Cpuid/Cpuid.c will cause GCC build error.

The patch removes the assumption that the resources claimed by root bridges should not exist. Because resources might have been added: 1. by platform modules either in PEI through resource HOB, or in DXE, before the PCI host bridge driver runs. 2. Resources claimed by different root bridges may overlap so that resource adding operation for latter root bridges may fail if we assume the resource should not exist. In real world, this patch is to fit OVMF platform needs because different root bridges in OVMF platform shares the same resources.

2016-02-24OvmfPkg: VirtioFlush(): return the number of bytes written by the hostLaszlo Ersek
VirtioLib provides an API for simple, synchronous (request/response-style) virtio communication. The guest driver builds one descriptor chain, link for link, with VirtioPrepare() and VirtioAppendDesc(), then submits the chain, and awaits the processing, with VirtioFlush(). The descriptor chain is always built at the beginning of the descriptor area, with the head descriptor having descriptor index 0. In order to submit the descriptor chain to the host, the guest always pushes a new "available element" to the Available Ring, in genuine queue-like fashion, with the new element referencing the head descriptor (which always has index 0, see above). In turn, after processing, the host always pushes a new "used element" to the Used Ring, in genuine queue-like fashion, with the new element referencing the head descriptor of the chain that was just processed. The same element also reports the number of bytes that the host wrote, consecutively across the host-writeable buffers that were linked by the descriptors. (See "OvmfPkg/VirtioNetDxe/TechNotes.txt" for a diagram about the descriptor area and the rings.) Because at most one descriptor chain can be in flight with VirtioLib at any time, - the Available Ring and the Used Ring proceed in lock-step, - and the head descriptor that the new "available" and "used" elements can ever reference has index 0. Based on the above, we can modify VirtioFlush() to return the number of bytes written by the host across the descriptor chain. The virtio-block and virtio-scsi drivers don't care (they have other ways to parse the data produced by the host), while the virtio-net driver doesn't use VirtioFlush() at all (it employs VirtioLib only to set up its rings). However, the virtio entropy device, to be covered in the upcoming patches, reports the amount of randomness produced by the host only through this quantity.

2016-02-24MdeModulePkg: AcpiTableDxe: make 4 GB table allocation limit optionalArd Biesheuvel
AARCH64 systems never require compatibility with legacy ACPI OSes, and may not have any 32-bit addressable system RAM. To support ACPI on these systems, we need to be able to relax the 4 GB allocation restriction. So add a PCD PcdAcpiExposedTableVersions containing a bitmask describing which ACPI versions are targeted, and wire it up it up to the memory allocation calls in AcpiTableDxe/AcpiTableProtocol.c. I.e., if ACPI v1.0b is not among the supported versions, the memory allocations are not limited to 4 GB, and only table types that carry 64-bit addresses are emitted. Note that this will inhibit the publishing of any tables that carry only 32-bit addresses, i.e., RSDPv1, RSDTv1 and RSDTv3.

2016-02-24ShellPkg: Support finding help message embedded in resource section.Qiu Shumin
UEFI Shell scandalizes the help message in spec level so that a standalone UEFI shell application can never get "-?" switch, instead the Shell core (interpreter) detects the "-?" and finds .MAN file for that shell application in certain spec defined paths, then show the help extracted from that .MAN file. But it means distributing a UEFI shell application not only means distributing a .EFI file but also distributing a .MAN file. If the text formatted .MAN file is corrupted (edited by user by mistake), or is missing (deleted by user by mistake), no help will be shown to user. So this patch enhance the Shell to make it support finding help message imbedded in resource section of application image.
