2016-10-15ArmVirtPkg: undo bogus component name and driver diagnostics disablementLaszlo Ersek
The entry point function of any UEFI_DRIVER that conforms to the UEFI driver model must install an instance of the EFI_DRIVER_BINDING_PROTOCOL on the image handle. Beyond that, the following protocols are optional: - EFI_COMPONENT_NAME_PROTOCOL - EFI_COMPONENT_NAME2_PROTOCOL - EFI_DRIVER_CONFIGURATION_PROTOCOL - EFI_DRIVER_CONFIGURATION2_PROTOCOL - EFI_DRIVER_DIAGNOSTICS_PROTOCOL - EFI_DRIVER_DIAGNOSTICS2_PROTOCOL The UefiLib functions - EfiLibInstallAllDriverProtocols() - EfiLibInstallAllDriverProtocols2() - EfiLibInstallDriverBindingComponentName2() are convenience helpers for such UEFI_DRIVERs. They simplify the installation of the above protocols. The UefiLib instance in "MdePkg/Library/UefiLib/UefiDriverModel.c" allows platforms to control these functions through the MdePkg feature PCDs - PcdComponentNameDisable - PcdComponentName2Disable - PcdDriverDiagnosticsDisable - PcdDriverDiagnostics2Disable If any of these PCDs are set to TRUE, then the helper functions will not install the corresponding protocol interfaces on the image handle, even if the driver passes in non-NULL protocol interfaces. In other words, at build time, a platform can forcibly prevent all drivers that employ UefiLib from producing these protocols. In ArmVirtPkg, that's what we've been doing forever, for no reason at all. This is why we haven't been seeing component and driver names from the DH, DEVICES, DRIVERS and DEVTREE shell commands, unlike in OvmfPkg. The default value for all these PCDs is FALSE, in "MdePkg/MdePkg.dec". Revert ArmVirtPkg to the sane defaults. This bug dates back to the inception of ArmVirtPkg (called ArmPlatformPkg/ArmVirtualizationPkg at the time).

The BaseMemoryLibStm implementation under ArmPkg/ is being deprecated, in favor of the generic versions under MdePkg, now that ARM and AARCH64 support has been added to both the generic C version (BaseMemoryLib) and the accelerated version (BaseMemoryLibOptDxe). The latter uses unaligned accesses and special cache maintenance instructions, and can therefore not be used when the MMU is off.

2016-09-08ArmVirtPkg: restrict mapping attributes of normal memory to EFI_MEMORY_WBArd Biesheuvel
In general, on an ARM system, mapping normal memory as device memory may have unintended side effects, given that unaligned accesses or loads and stores with special semantics (e.g., load/store exclusive) may fault or may not work as expected. Under KVM, the situation is even worse, since the host may not expect the guest to perform uncached accesses, and so writes to such an uncached region may get lost completely. Since the only safe mapping type under KVM is EFI_MEMORY_WB, remove all other memory type attributes.

2016-09-02ArmVirtPkg/PciHostBridgeDxe: don't set linux,pci-probe-only DT propertyArd Biesheuvel
Setting the linux,pci-probe-only was intended to align OSes booting via DT with OSes booting via ACPI in the way they honor the PCI configuration performed by the firmware. However, ACPI on arm64 does not currently honor the firmware's PCI configuration, and the linux,pci-probe-only completely prevents any PCI reconfiguration from occurring under the OS, including what is needed to support PCI hotplug. Since the primary use case was OS access to the GOP framebuffer (which breaks when the framebuffer BAR is moved when the OS reconfigures the PCI), we can undo this change now that ArmVirtQemu has moved to a GOP implementation that does not expose a raw framebuffer in the first place.

The clang developers have made a backward incompatible change to the command line arguments, and have replaced '-mllvm -arm-use-movt=0' with '-mno-movt'. This does not matter for most ARM platforms, and therefore it has been removed from the default CLANG35/ARM CC flags in patch 1c63516075b3 ("BaseTools CLANG35: drop problematic use-movt and save-temps options"), but as it turns out, the relocatable PrePi implementation used by ArmVirtQemuKernel and ArmVirtXen will fail to build if it contains MOVT/MOVW pairs, due to the fact that these are not runtime relocatable under ELF. Since they are runtime relocatable under PE/COFF, and GenFw does the right thing when encountering them, selectively controlling their use is more appropriate than disabling them altogether. Therefore, this patch adds the -mno-movt argument only for the platforms that use the relocatable PrePi, and only for the module types that may be pulled into its build. In addition, switch to the SEC type version of ArmLib, so that the relocatable PrePi only depends on BASE and SEC type libraries.

2016-07-13ArmVirtPkg/PlatformBootManagerLib: remove stale FvFile boot optionsLaszlo Ersek
(This patch ports OvmfPkg commit 2eb358986052 to ArmVirtPkg. That functionality was not added to QemuBootOrderLib, because it was (and is) independent from QEMU and fw_cfg.) Remove any boot options that point to binaries built into the firmware and have become stale due to any of the following: - FvMain's base address or size changed (historical -- see commit e191a3114f4c), - FvMain's FvNameGuid changed, - the FILE_GUID of the pointed-to binary changed, - the referenced binary is no longer built into the firmware. For example, multiple such "EFI Internal Shell" boot options can coexist. They technically differ from each other, but may not describe any built-in shell binary exactly. Such options can accumulate in a varstore over time, and while they remain generally bootable (thanks to the efforts of BmGetFileBufferByFvFilePath()), they look bad. Filter out any stale options.

2016-07-12ArmVirtPkg: add name GUIDs to FvMain instancesArd Biesheuvel
Assign name GUIDs to the FVs that may appear in DevicePath references to things like the UiApp and the UEFI Shell. This prevents these device paths from changing inadvertently when the FV ends up in a different memory location due to external occurrences such as, e.g., a change in the amount of system memory.

2016-07-12ArmVirtPkg: factor out Rules FDF sectionArd Biesheuvel
All three current ArmVirtPkg have identical [Rules] sections in their FDF definitions, and ideally, they should remain that way. So factor out the definitions into a separate include file, and replace the existing definitions with !include directives.

The FDF definition of [FV.FvMain] is identical between ArmVirtQemu and ArmVirtQemuKernel, and needs to remain that way. So factor it out into a separate include file, and replace both definitions with an !include directive.

2016-07-12ArmVirtPkg: align ArmVirtQemuKernel with ArmVirtQemuArd Biesheuvel
The platform ArmVirtQemuKernel is intended as an alternative for ArmVirtQemu that only deviates in the way it is invoked by QEMU, either from flash address 0x0 (the default ARM reset vector) or via the Linux kernel boot protocol. So add VirtioRngDxe and HighMemDxe here as well.

The reasoning of patch 8e2efec6b206: No ARM support for ACPI is planned under any OS we intend to run under ArmVirtQemu-ARM, so remove the drivers from the ARM build. applies equally to ArmVirtQemuKernel, so apply the same change there.

2016-07-12ArmVirtPkg/HighMemDxe: allow patchable PCD for PcdSystemMemoryBaseArd Biesheuvel
Redefine the reference to PcdSystemMemoryBase in HighMemDxe.inf as a plain [Pcd] rather than [FixedPcd] (and fix up the code as appropriate). This allows us to align ArmVirtQemuKernel with ArmVirtQemu, given that the former uses a patchable PCD not a fixed PCD.

2016-07-08ArmVirtPkg/PlatformBootManagerLib: Postpone the shell registrationLaszlo Ersek
This patch ports Gary's OvmfPkg commit 14b2ebc30c8b to ArmVirtPkg. Turns out Gary's argument in 14b2ebc30c8b is not only valid for Xen. The same situation arises with QEMU if: - the user specifies no boot order via fw_cfg at all (so QemuBootOrderLib won't touch the boot order), and - the varstore file has just been created from the varstore template. In this case the user is dropped to the UEFI shell (because the shell is registered earlier than all the auto-generated options), which is likely not what the user wants.

Switch all users of ArmLib that depend on the MMU routines to the new, separate ArmMmuLib. This needs to occur in one go, since the MMU routines are removed from ArmLib build at the same time, to prevent conflicting symbols.
