2015-12-17ArmVirtPkg/ArmVirtXen: add ARM supportArd Biesheuvel2-6/+22
This adds ARM support to the ArmVirtXen platform. As is the case for AARCH64, the ARM port adheres to the ARM Linux boot protocol, i.e., it expects the address of a DTB describing the platform to be passed in r2, and relocates itself at runtime to the actual load time memory offset.

2015-11-26ArmVirtPkg: Use SerialDxe in MdeModulePkg instead of EmbeddedPkgStar Zeng7-6/+180
Beyond just changing the directly related lines in the FDF and DSC files, we have to adapt the EarlyFdtPL011SerialPortLib and FdtPL011SerialPortLib instances as well, in the same patch. This is because the EmbeddedPkg driver expects the SerialPortSetAttributes(), SerialPortSetControl() and SerialPortGetControl() functions from SerialPortExtLib, while the MdeModulePkg driver expects them from SerialPortLib itself. We cannot implement these functions in ArmVirtPkg's SerialPortLib instances *before* flipping the driver, because it would cause double function definitions in the EmbeddedPkg driver. We also can't implement the functions *after* flipping the driver, because it would cause unresolved function references in the MdeModulePkg driver. Therefore we have to implement the functions simultaneously with the driver replacement.

2015-11-24ArmVirtPkg/ArmVirtPlatformLib: reduce ID map size to GCD region sizeArd Biesheuvel2-1/+4
The ID mapping routines on virtual platforms simply map the entire hardware supported physical address space as device memory, and then punch some holes for regions that need to be mapped cacheable. On virtual platforms hosted on CPUs that support a large physical address range, this may result in a lot of overhead, i.e., 4 KB of page tables for each 512 GB of address space, which quickly adds up (i.e., 2 MB for the architectural maximum of 48 bits). Since there may be a platform specific limit to the size of the (I)PA space that is not reflected by CPU id registers, restrict the range of the ID mapping to gEmbeddedTokenSpaceGuid.PcdPrePiCpuMemorySize bits. This makes sense by itself, since we cannot manipulate mappings above that limit anwyay (because they are not covered by GCD), and it allows the PCD be set to a lower value by platforms whose (I)PA space is smaller than the hardware supported maximum.

2015-11-18ArmVirtPkg/ArmVirtPlatformLib: map executable NOR region as normal memoryArd Biesheuvel1-2/+8
The ARM architecture version 7 and later mandates that device mappings have the XN (non-executable) bit set, to prevent speculative instruction fetches from read-sensitive regions. This implies that we should not map regions as device if we want to execute from them, so the NOR region that contains our FD image should be mapped as normal memory instead. The MMU code deals correctly with overlapping ARM_MEMORY_REGION_DESCRIPTOR entries, and later entries in the array take precedence over earlier ones. So simply add an entry to the end of the array that overrides the mapping attributes of the FD image, wherever it resides.

2015-09-22ArmVirtPkg: reduce preallocation of boot services data pagesArd Biesheuvel1-1/+1
Commit SVN r18503 ("MdeModulePkg DxeCore: Take the range in resource HOB for PHIT as higher priority") changed the GCD init logic to take the sum of the region sizes in gMemoryTypeInformation[] into account when estimating the minimal amount of memory needed to boot the system. Unfortunately, as an unintended side effect, this change results in boot failures of ArmVirtQemu when running with QEMU's default memory size of 128 MB. The reason is that the sum of the gMemoryTypeInformation region sizes plus the size of the inital PEI region exceeds 128 MB. Since we do not actually need to preallocate 20,000 pages' worth of BootServicesData memory, reduce this figure to the more reasonable 12,000.

At least two edk2-wide callbacks are worth mentioning: - OnReadyToBoot() in "MdeModulePkg/Universal/Variable/RuntimeDxe/VariableDxe.c" performs variable reclaim and (optionally) installs variable usage statistics as a vendor config table; - OnReadyToBoot() in "SecurityPkg/Library/DxeImageVerificationLib/DxeImageVerificationLib.c" installs the image execution info table if it doesn't exist yet, in SecureBoot-enabled builds.

2015-08-06ArmVirtPkg: set default for PcdSmbiosDocRevLaszlo Ersek1-0/+1
When MdeModulePkg/Universal/SmbiosDxe is instructed to compose & install an SMBIOS 3.0 entry point, it keys the Docrev (specification document revision) field of that structure off of PcdSmbiosDocRev. An upcoming OvmfPkg patch will have OvmfPkg/Library/SmbiosVersionLib set this PCD dynamically. Because we use that driver in the ArmVirtQemu.dsc platform, we must provide a default for the dynamic PCD.

QemuFwCfgToPcdDxe This patch de-duplicates the logic added in commit ArmVirtPkg: QemuFwCfgToPcdDxe: set SMBIOS entry point version dynamically (git c98da334, SVN r18043) by hooking DetectSmbiosVersionLib into SmbiosDxe. Although said commit was supposed to work with SMBIOS 3.0 payloads from QEMU, in practice that never worked, because the size / signature checks in SmbiosVersionInitialization() would always fail, due to the SMBIOS 3.0 entry point being structurally different. Therefore this patch doesn't regress ArmVirtPkg.

2015-07-28ArmPkg: split off ArmGicArchLib from ArmGicLibArd Biesheuvel1-0/+1
The current implementation of ArmGicGetSupportedArchRevision () that is used by all ARM platforms is entirely stateless (in order to support being executed from flash) so it needs to interrogate the hardware for the supported GIC revision upon each invocation. However, this statelessness is only needed for SEC type modules; in all other cases, we could easily determine the GIC revision once, and store the result in a global variable. In preparation of having separate early and normal versions, this patch introduces the ArmGicArchLib library class and default implementation, and moves the existing ArmGicGetSupportedArchRevision () into it.

2015-07-26ArmVirtPkg: QemuFwCfgToPcdDxe: set SMBIOS entry point version dynamicallyLaszlo Ersek3-0/+49
(This patch parallels OvmfPkg commit 37baf06b (SVN r17676).) PcdSmbiosVersion controls the version number of the SMBIOS entry point table (and other, related things) that the universal "MdeModulePkg/Universal/SmbiosDxe" driver, providing EFI_SMBIOS_PROTOCOL, installs. The "virt" machine type of QEMU generates SMBIOS payload for the firmware to install. The payload includes the entry point table ("anchor" table). OvmfPkg/SmbiosPlatformDxe cannot install the anchor table (because that is the jurisdiction of the generic "MdeModulePkg/Universal/SmbiosDxe" driver); however, we can parse the entry point version from QEMU's anchor table, and instruct "MdeModulePkg/Universal/SmbiosDxe" to adhere to that version. As default for PcdSmbiosVersion we should keep the current 0x0300 value (ie. SMBIOS 3.0) from "MdeModulePkg/MdeModulePkg.dec"; that spec version was specifically created for ARM / AARCH64 needs.

2015-07-26ArmVirtPkg: add QemuFwCfgToPcdDxeLaszlo Ersek4-0/+78
Many universal DXE drivers in edk2 can be controlled by setting dynamic PCDs. Such a PCD must be set before the consumer DXE driver is dispatched. (In general we assume that the DXE driver will consume the PCD in its entry point, or in the constructor of a library instance it links against. In special cases this requirement can be relaxed a bit, if we know that the DXE driver accesses the PCD only in a protocol member function that it exports.) On the QEMU platform, the PCD values to be set for the universal drivers are frequently derived from fw_cfg files that QEMU exports. In OvmfPkg we tend to handle this in the following way: - For IA32 and X64, OvmfPkg provides a QemuFwCfgLib instance that is usable in PEI. - In PlatformPei, fw_cfg files can be loaded and transformed to PCD values. - Any DXE driver is bound to be dispatched after the PEI phase is done. (In specific cases other ordering solutions might be possible, via Depex or protocol notify, etc.) In ArmVirtPkg/ArmVirtQemu, things differ a bit: - We don't have an ArmVirtPkg-specific ("Platform") PEIM. This is actually a good thing for now, so let's not introduce one just for this purpose. - Even if we had such a PEIM, it could not easily access fw_cfg: the MMIO addresses of the fw_cfg device are available only in the DTB that QEMU exports. (Accordingly, our QemuFwCfgLib instance is restricted to DXE_DRIVER modules: VirtFdtDxe parses the DTB, stores the fw_cfg addresses in PCDs, and then QemuFwCfgLib's constructor fetches those PCDs.) There are some examples in ArmVirtPkg where early code is forced to parse the DTB manually, but those examples are all painful, and our goal here (controlling universal DXE drivers) doesn't justify more of that pain. Therefore, introduce a separate, minimal DXE driver that is dispatched strictly after VirtFdtDxe (so that it can use QemuFwCfgLib), and strictly before other DXE drivers (so that it can set dynamic PCDs for them). Because VirtFdtDxe is already ordered with the APRIORI DXE file, it is simplest to do the same for the new driver. Actual fw_cfg files and PCDs shall be accessed in future patches.

2015-07-16ArmVirtPkg: Make terminal type consistentHeyi Guo1-0/+8
Change default terminal type to be consistent with default ConIn/ConOut device path, which is now determined by TTY_TERMINAL flag, TTYTERM or VT100. I can't say this is a bug, as we can pass the whole console device path to ConnectController, and TerminalDxe driver will pick up the terminal in the remaining device path. However, in rare circumstances, the console devices may be disconnected with the driver, and they will be ignored by ConPlatformDxe until we pass the device path explicitly just as BDS. Changing default terminal type to be the same with console device path could help serial terminal be reconnected with normal connect controller operation.
