2017-03-28EmbeddedPkg: introduce EDKII Platform Has ACPI GUIDLaszlo Ersek
The presence of this GUID in the PPI database, and/or in the DXE protocol database (as dictated by the platform's needs in these firmware phases) implies that the platform provides the operating system with an ACPI-based hardware description. This is not necessarily exclusive with other types of hardware description (for example, a Device Tree-based one). A platform PEIM and/or DXE driver is supposed to produce a single instance of the PPI and/or protocol (with NULL contents), if appropriate. The decision to produce the PPI and/or protocol is platform specific; for example, in the DXE phase, it could depend on an HII checkbox / underlying non-volatile UEFI variable. In the DXE phase, the protocol is meant to be depended-upon by "MdeModulePkg/Universal/Acpi/AcpiTableDxe", indirectly: * In the long term, interested platforms will establish this dependency by hooking an (upcoming) NULL-class DepexLib instance into AcpiTableDxe in their DSC files, pointing DepexLib's DEPEX through a FixedAtBuild PCD to the GUID introduced here. (For the prerequisite BaseTools feature, refer to <https://bugzilla.tianocore.org/show_bug.cgi?id=443>). * In the short term, an interested platform may hook a private NULL-class library instance (called e.g. "PlatformHasAcpiLib") into AcpiTableDxe. Such a library instance would be a specialization of the above described generic DepexLib, with the DEPEX open-coded on the GUID introduced here. Either way, the platform makes EFI_ACPI_TABLE_PROTOCOL and (if enabled) EFI_ACPI_SDT_PROTOCOL dependent on the platform's dynamic decision to produce or not to produce a NULL protocol instance with this GUID. In turn, other (platform and universal) DXE drivers that produce ACPI tables will wait for EFI_ACPI_TABLE_PROTOCOL / EFI_ACPI_SDT_PROTOCOL, via DEPEX, protocol notify, or a simple gBS->LocateProtocol() in a "late enough" callback (such as Ready To Boot). Because this GUID is not standard, it is prefixed with EDKII / Edkii, as seen elsewhere in MdeModulePkg and SecurityPkg. In addition, an effort is made to avoid the phrase "AcpiPlatform", as that belongs to drivers / libraries that produce platform specific ACPI content (as opposed to deciding whether the entire firmware will have access to EFI_ACPI_TABLE_PROTOCOL, or any similar facilities in the PEI phase).

2017-03-28Revert "ArmVirtPkg/FdtClientDxe: install DT configuration table at ReadyToBoot"Laszlo Ersek
This reverts commit 18f6d4df9ece8b91b86511bcdd1cf7da478c3627. We realized that DXE drivers that are independent of AcpiPlatformDxe (that is, independent of QEMU's ACPI generation), such as RamDiskDxe and BootGraphicsResourceTableDxe, may produce and/or manipulate ACPI tables, at driver dispatch or even at Ready To Boot. This makes it unsafe for us to check for ACPI presence in the UEFI system config table in a Ready To Boot callback, in order to decide about exposing the DT.

The current CPU_REGISTER_TABLE_ENTRY structure only defined UINT32 Index to indicate MSR/MMIO address. It's ok for MSR because MSR address is UINT32 type actually. But for MMIO address, UINT32 limits MMIO address exceeds 4GB. This update on CPU_REGISTER_TABLE_ENTRY is to add additional UINT32 field HighIndex to indicate the high 32bit MMIO address and original Index still indicate the low 32bit MMIO address.

2017-03-25BaseTools: Skip module AutoGen by comparing timestamp.Derek Lin
[Introduction] The BaseTool Build.py AutoGen parse INF meta-file and generate AutoGen.c/AutoGen.h/makefile. When we only change .c .h code, the AutoGen might be not necessary, but Build.py spend a lot of time on it. There's a -u flag to skip all module's AutoGen. In my environment, it save 35%~50% of time in rebuild a ROM. However, if user change one .INF meta-file, then -u flag is not available. [Idea] AutoGen can compare meta-file's timestamp and decide if the module's AutoGen can be skipped. With this, when a module's INF is changed, we only run this module's AutoGen, we don't need to run other module's. [Implementation] In the end of a module's AutoGen, we create a AutoGenTimeStamp. The file save a file list that related to this module's AutoGen. In other word, the file list in AutoGenTimeStamp is INPUT files of module AutoGen, AutoGenTimeStamp file is OUTPUT. During rebuild, we compare time stamp between INPUT and OUTPUT, and decide if we can skip it. Below is the Input/Output of a module's AutoGen. [Input] 1. All the DSC/DEC/FDF used by the platform. 2. Macro and PCD defined by Build Options such as "build -D AAA=TRUE --pcd BbbPcd=0". 3. INF file of a module. 4. Source files of a module, list in [Sources] section of INF. 5. All the library link by the module. 6. All the .h files included by the module's sources. [Output] AutoGen.c/AutoGen.h/makefile/AutoGenTimeStamp [Testing] This patch save my build time. When I make a change without touching DSC/DEC/FDF, it is absolutely much faster than original rebuild, 35%~50% time saving in my environment (compare to original tool rebuild time). If I change any DSC/DEC/FDF, there's no performance improve, because it can't skip any module's AutoGen. Please note that if your environment will generate DSC/FDF during prebuild, it will not skip any AutoGen because of DSC timestamp is changed. This will require prebuild script not to update metafile when content is not changed.
2017-03-23MdePkg/DevicePathLib: Fix FromText bug for multi-instance devicepathRuiyu Ni
UefiDevicePathLibConvertTextToDevicePath correctly detects when it has hit a ',' splicing together multiple paths. However, the code that tries to cope with it: {code} if (IsInstanceEnd) { DeviceNode = (EFI_DEVICE_PATH_PROTOCOL *) AllocatePool ( END_DEVICE_PATH_LENGTH); ASSERT (DeviceNode != NULL); SetDevicePathEndNode (DeviceNode); NewDevicePath = AppendDevicePathNode (DevicePath, DeviceNode); FreePool (DevicePath); FreePool (DeviceNode); DevicePath = NewDevicePath; } {code} causes a problem. The END node that's appended it the node for the entire list. So when the node is appended in AppendDevicePathNode, it winds up disappearing. This leads to the path 'PciRoot(0x0),PciRoot(0x0)' parsing as if 'PciRoot(0x0)/PciRoot(0x0)' were specified. These are two very different things.

If PCD PcdCpuS3DataAddress is set before, CpuS3DataDxe should get RegisterTable and PreSmmRegisterTable from existing PCD pointed buffer and needn't to allocate new buffer for RegisterTable and PreSmmRegisterTable.

2017-03-22UefiCpuPkg/AcpiCpuData: Update RegisterTableEntry typeJeff Fan
Current RegisterTableEntry filed in CPU_REGISTER_TABLE is one pointer to CPU_REGISTER_TABLE_ENTRY. If CPU register table wants to be passed from 32bit PEI to x64 DXE/SMM, x64 DXE/SMM cannot get the correct RegisterTableEntry. This update is to update RegisterTableEntry type to EFI_PHYSICAL_ADDRESS and make RegisterTableEntry is fixed length.

2017-03-21MdeModulePkg/MemoryProtection: split protect and unprotect pathsArd Biesheuvel
Currently, the PE/COFF image memory protection code uses the same code paths for protecting and unprotecting an image. This is strange, since unprotecting an image involves a single call into the CPU arch protocol to clear the permission attributes of the entire range, and there is no need to parse the PE/COFF headers again. So let's store the ImageRecord entries in a linked list, so we can find it again at unprotect time, and simply clear the permissions. Note that this fixes a DEBUG hang on an ASSERT() that occurs when the PE/COFF image fails to load, which causes UnprotectUefiImage() to be invoked before the image is fully loaded.

2017-03-21ArmVirtPkg/HighMemDxe: check new regions against GCD memory space mapArd Biesheuvel
Instead of looking at the PCD gArmTokenSpaceGuid.PcdSystemMemoryBase to decide which DT node covers the memory we are already using, query the GCD memory space map, which is the authoritative source for this kind of information This fixes a problem observed by Michael on platforms where this PCD is of the 'Patchable' type, which means updates to its value do not propagate to other modules.

Instead of invoking gDS->SetMemorySpaceAttributes to set the EFI_MEMORY_XP attribute on newly added regions, which is guaranteed to fail if the same attribute was not declared as a capability of the region when it as added, invoke the CPU arch protocol directly to set the EFI_MEMORY_XP attribute if our memory protection policy demands it.

2017-03-21MdeModulePkg/BootGraphicsResourceTableDxe: don't allocate below 4 GBArd Biesheuvel
The BGRT table has an 8 byte field for the memory address of the image data, and yet the driver explicitly allocates below 4 GB. This results in an ASSERT() on systems that do not have any memory below 4 GB to begin with. Since neither the PI, the UEFI or the ACPI spec contain any mention of why this data should reside below 4 GB, replace the allocation call with an ordinary AllocatePages() call.
