* ArmPkg/ArmMmuLib AARCH64: avoid EL0 accessible mappingsArd Biesheuvel2022-02-012-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | We never run any code at EL0, and so it would seem that any access permissions set for EL0 (via the AP[1] attribute in the page tables) are irrelevant. We currently set EL0 and EL1 permissions to the same value arbitrarily. However, this causes problems on hardware like the Apple M1 running the MacOS hypervisor framework, which enters EL1 with SCTLR_EL1.SPAN enabled, causing the Privileged Access Never (PAN) feature to be enabled on any exception taken to EL1, including the IRQ exceptions that handle our timer interrupt. When PAN is enabled, EL1 has no access to any mappings that are also accessible to EL0, causing the firmware to crash if it attempts to access such a mapping. Even though it is debatable whether or not SCTLR_EL1.SPAN should be disabled at entry or whether the firmware should put all UNKNOWN bits in all system registers in a consistent state (which it should), using EL0 permissions serves no purpose whatsoever so let's fix that regardless.

* ArmPkg: Implement PlatformBootManagerLib for LinuxBootNhi Pham2021-10-234-0/+254
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | LinuxBoot is a firmware that replaces specific firmware functionality like the UEFI DXE phase with a Linux kernel and runtime. It is built-in UEFI image like an application, which is executed at the end of DXE phase. To achieve the LinuxBoot boot flow "SEC->PEI->DXE->BDS->LinuxBoot", today we use the common well-known GUID of UEFI Shell for LinuxBoot payload, so LinuxBoot developers can effortlessly find the UEFI Shell Application and replace it with the LinuxBoot payload without recompiling platform EDK2 (There might be an issue with a few systems that don't have a UEFI Shell). Also, we have a hard requirement to force the BDS to boot into the LinuxBoot as it is essentially required that only the LinuxBoot boot option is permissible and UEFI is an intermediate bootstrap phase. Considering all the above, it is reasonable to just have a new GUID for LinuxBoot and require a LinuxBoot specific BDS implementation. In addition, with making the BDS implementation simpler, we can reduce many DXE drivers which we think it is not necessary for LinuxBoot booting. This patch adds a new PlatformBootManagerLib implementation which registers only the gArmTokenSpaceGuid.PcdLinuxBootFileGuid for LinuxBoot payload as an active boot option. It allows BDS to jump to the LinuxBoot quickly by skipping the UiApp and UEFI Shell. The PlatformBootManagerLib library derived from ArmPkg/Library/PlatformBootManagerLib.

* ArmPkg/GicV3Dxe: Don't signal EOI on arbitrary interruptsArd Biesheuvel2021-08-271-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, at ExitBootServices() time, the GICv3 driver signals End-Of-Interrupt (EOI) on all interrupt lines that are supported by the interrupt controller. This appears to have been carried over from the GICv2 version, but has been turned into something that violates the GIC spec, and may trigger SError exceptions on some implementations. Marc puts it as follows: The GIC interrupt state machine is pretty strict. An interrupt can only be deactivated (with or without prior priority drop) if it has been acknowledged first. In GIC speak, this means that only the following sequences are valid: With EOImode==0: x = ICC_IAR{0,1}_EL1; ICC_EOIR{0,1}_EL1 = x; With EOImode==1: x = ICC_IAR{0,1}_EL1; ICC_EOIR{0,1}_EL1 = x; ICC_DIR_EL1 = x; Any write to ICC_EOIR{0,1}_EL1 that isn't the direct consequence of the same value being read from ICC_IAR{0,1}_EL1, and with the correct nesting, breaks the state machine and leads to unpredictable results that affects *all* interrupts in the system (most likely, the priority system is dead). See Figure 4-3 ("Interrupt handling state machine") in Arm IHI 0069F for a description of the acceptable transitions. Additionally, on implementations that have ICC_CTLR_EL1.SEIS==1, a SError may be generated to signal the error. See the various <quote> IMPLEMENTATION_DEFINED "SError ...."; </quote> that are all over the pseudocode contained in the same architecture spec. Needless to say, this is pretty final for any SW that would do silly things on such implementations (which do exist). Given that in our implementation, every signalled interrupt is acked, handled and EOId in sequence, there is no reason to EOI all interrupts at ExitBootServices() time in the first place, so let's just drop this code. This fixes an issue reported by Marc where an SError is triggered by this code, bringing down the system.

* ArmPkg: Add missing library headers to ArmPkg.decPierre Gondois2021-04-281-3/+9
| | | | | | | | | | | | | | | | | | | | | | | Some library headers are missing/incorrect in ArmPkg.dec. This makes the 'LibraryClassCheck' CI test fail. This patch adds/corrects them. According to .pytool/Readme about the 'LibraryClassCheck' test: This test scans at all library header files found in the `Library` folders in all of the package's declared include directories and ensures that all files have a matching LibraryClass declaration in the DEC file for the package.
