* ArmVirtPkg: implement ArmVirtPsciResetSystemPeiLibArd Biesheuvel2020-03-042-0/+271
| | | | | | | | | | | | | | | Implement a ArmVirtPkg specific version of the PSCI ResetSystemLib that is usable in the PEI phase, as the existing one relies on the FDT client protocol, making it unsuitable. Note that accessing the device tree passed by QEMU via its initial base address is guaranteed to be safe at any time during the PEI phase, so we can defer discovery of the PSCI method until the time the reset library is actually invoked (which is rarely) Ref: https://bugzilla.tianocore.org/show_bug.cgi?id=2560 Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Acked-by: Laszlo Ersek <lersek@redhat.com>
* ArmVirtPkg/PlatformPeiLib: discover the TPM base address from the DTArd Biesheuvel2020-03-046-14/+129
| | | | | | | | | | | | | | | | | Introduce a boolean PCD that tells us whether TPM support is enabled in the build, and if it is, record the TPM base address in the existing routine that traverses the device tree in the platform PEIM. If a TPM is found, install the gOvmfTpmDiscoveredPpiGuid signalling PPI that will unlock the dispatch of OvmfPkg's Tcg2ConfigPei. If TPM2 support is enabled in the build but no TPM2 device is found, install the gPeiTpmInitializationDonePpiGuid PPI, which is normally installed by Tcg2ConfigPei if no TPM2 is found, but in our case Tcg2ConfigPei will never run so let's do it here instead.

* ArmVirtPkg/PlatformPeiLib: make PcdLib dependency explicit in .INFArd Biesheuvel2020-03-041-0/+1
| | | | | | | | | | | | | | We currently include PcdLib.h in PlatformPeiLib, without declaring this dependency in its .INF description. Since all the PCDs we use resolve to fixed type in practice, this does not really matter at the moment, but since we will be adding dynamic PCD references in a subsequent patch, let's make the PcdLib dependency explicit, so that its dispatch is guaranteed to be ordered correctly with respect to the provider of the dynamic PCD PPI.

* ArmVirtPkg: increase FD/FV size for NOOPT buildsArd Biesheuvel2019-09-134-9/+68
| | | | | | | | | | | | | | | After upgrading the CI system we use for building the ArmVirtPkg targets, we started seeing failures due to the NOOPT build running out of space when using the CLANG38 toolchain definition combined with clang 7. We really don't want to increase the FD/FV sizes in general to accommodate this, so parameterize the relevant quantities and increase them by 50% for NOOPT builds.

* ArmVirtPkg/PlatformBootManagerLib: unload image on EFI_SECURITY_VIOLATIONLaszlo Ersek2019-09-051-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The LoadImage() boot service is a bit unusual in that it allocates resources in a particular failure case; namely, it produces a valid "ImageHandle" when it returns EFI_SECURITY_VIOLATION. This is supposed to happen e.g. when Secure Boot verification fails for the image, but the platform policy for the particular image origin (such as "fixed media" or "removable media") is DEFER_EXECUTE_ON_SECURITY_VIOLATION. The return code allows platform logic to selectively override the verification failure, and launch the image nonetheless. ArmVirtPkg/PlatformBootManagerLib does not override EFI_SECURITY_VIOLATION for the kernel image loaded from fw_cfg -- any LoadImage() error is considered fatal. When we simply treat EFI_SECURITY_VIOLATION like any other LoadImage() error, we leak the resources associated with "KernelImageHandle". From a resource usage perspective, EFI_SECURITY_VIOLATION must be considered "success", and rolled back. Implement this rollback, without breaking the proper "nesting" of error handling jumps and labels.

* ArmVirtPkg/ArmVirtPrePiUniCoreRelocatable: revert to PIE linkingArd Biesheuvel2019-09-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | In some cases, the CLANG38 toolchain profile in LTO mode emits GOT based relocations in spite of our attempts to avoid this, by using hidden visibility, -Bsymbolic etc. On AARCH64, we managed to work around this by processing the GOT based relocations in GenFw. As it turns out, the same issue exists on 32-bit ARM, but unfortunately, we cannot use a similar trick to get rid of the GOT entry, and the relocation metadata is insufficient to locate the GOT entry in the binary. Note that in this particular case, we are interested in PIE linking only (i.e., producing a .rela section containing dynamic relocations that the startup code can process directly), and not in position independent code generation, and by passing the -pie option to the linker directly using -Wl,-pie (and dropping -shared), we can coerce the GOLD linker into doing only the former rather than both when it performs its LTO code generation.

* ArmVirtPkg/ArmVirtQemu*: enable minimal Status Code Routing in DXELaszlo Ersek2019-02-253-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The EFI_RETURN_STATUS_EXTENDED_DATA feature from PI-1.7 (<https://mantis.uefi.org/mantis/view.php?id=1885>) enables platform code to learn about boot option failures (loading and launching) via status codes reported by the UEFI Boot Manager. In commit 59541d41633c, we removed all status code support from ArmVirtPkg. Reenable that support now, minimally, just to the extent so we can benefit from the PI-1.7 feature mentioned above: (1) Include the ReportStatusCodeRouterRuntimeDxe driver. This driver produces two protocols, EFI_STATUS_CODE_PROTOCOL and EFI_RSC_HANDLER_PROTOCOL. The former allows DXE phase modules and runtime modules to report (produce) status codes. The latter allows the same types of modules to register callbacks for status code handling (consumption). (Handler registration occurs only at boot time. Status codes are delivered to each handler at runtime as well, unless the handler is unregistered at ExitBootServices().) (2) Resolve ReportStatusCodeLib to a non-Null instance, for DXE_DRIVER modules only. This way DXE_DRIVER modules that use the REPORT_STATUS_CODE_EX() macro and friends will reach EFI_STATUS_CODE_PROTOCOL from point (1). (3) Set PcdReportStatusCodePropertyMask to 3 (the default value is 0). This causes the REPORT_STATUS_CODE_EX() macro and friends to let Progress Codes (bit#0) and Error Codes (bit#1) through to point (1). Debug Codes (bit#2) are filtered out. (4) Include no driver, for now, that registers any status code handler via EFI_RSC_HANDLER_PROTOCOL, from point (1). Status codes that reach ReportStatusCodeRouterRuntimeDxe will be thrown away. (5) Modify only the ArmVirtQemu* platforms. A status code handler will be added to "ArmVirtPkg/Library/PlatformBootManagerLib" in the next patch, and this library instance is not consumed by ArmVirtXen.

This was introduced for 32-bit ARM, which may support more than 4 GB of physical address space, but cannot address all of it via a 1:1 mapping, and a single region that is not mappable in its entirety is unusable by the PEI core. AArch64 is in a similar situation now: platforms may support more than 256 TB of physical address space, but only 256 TB is addressable by the CPU, and so a memory region that extends from below this limit to above it should be split.

* ArmVirtPkg/PrePiUniCoreRelocatable CLANG38: work around build issuesArd Biesheuvel2018-12-114-5/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The self-relocating PrePi module that is used by the ArmVirtQemuKernel and ArmVirtXen targets runs the linker in PIE mode so that it emits dynamic relocations into the final image in a way that permits the module to relocate itself into place before calling into the C code. When building these targets using the CLANG38 toolchain, we switch from the BFD to the GOLD linker, which behaves a bit differently when building PIE executables, and insists on emitting GOT indirected symbol references throughout, which means a) that we end up with absolute addresses (which need to be fixed up at load time) for no good reason, and b) we have to add support for handling GOT entries to GenFw if we want to convert them into PE/COFF. So instead, let's emit a shared library. Since the ELF image only serves as the input to GenFw, this does not lead to any loss of functionality, although it does require the -Bsymbolic linker option to be added to ensure that no symbol based dynamic relocations are emitted (which would, e.g., permit lazy binding for shared libraries). So for all other toolchains, the linker option changes are a no-op. Then, we have to convince CLANG38/GOLD that there is no need to refer to symbols via a GOT entry. This is done by forcing hidden visibility for all symbols in all components that make up the PrePi SEC module: this informs the linker that a symbol is never exported or preempted, making it safe to refer to it directly from anywhere in the code, rather than indirectly via a GOT entry.

Given that the first page of the flash device is not actually used anyway, let's reduce the mappings of the peripheral space and the flash device (both of which cover page #0) to only cover what is actually required: ArmVirtQemu.fdf: > 0x00001000|0x001ff000 > gArmTokenSpaceGuid.PcdFvBaseAddress|gArmTokenSpaceGuid.PcdFvSize ArmVirtQemuKernel.fdf: > 0x00008000|0x001f8000 > gArmTokenSpaceGuid.PcdFvBaseAddress|gArmTokenSpaceGuid.PcdFvSize For ArmVirtQemu, the resulting virtual mapping looks roughly like: - [0, 4K) : flash, unmapped - [4K, 2M) : flash, mapped as WB+X RAM - [2M, 64M) : flash, unmapped - [64M, 128M) : varstore flash, will be mapped by the NOR flash driver - [128M, 256M) : peripherals, mapped as device - [256M, 1GB) : 32-bit MMIO aperture, translated IO aperture, ECAM, will be mapped by the PCI host bridge driver - [1GB, ...) : RAM, mapped. After this change, any inadvertent read or write from/to the first physical page will trigger a translation fault inside the guest, regardless of the nature of the instruction, without crashing QEMU.
