* ArmPlatformPkg: Honour RES1 fields in CPTR_EL2Jessica Clarke2024-11-141-1/+2
| | | | | | | | | | | | | | | | | | | | | | | Unlike CPACR_EL1 whose reserved bits are solely RES0, CPTR_EL2 has some RES1 bits, and so we should not clear them unless we know what they mean. For example, when SVE was introduced, CPACR_EL1.ZEN occupied a RES0 field and thus 0 means trap (which is what we get at EL1), but CPTR_EL2.TZ occupied a RES1 field and thus 1 means trap, but we set it to 0, so the environment is inconsistent between EDK2 and EL1 and EL2. Another concrete case is for Morello, where the CEN/TC fields similarly gate access to capability register state, but also alter exception delivery and return, such that VBAR_ELx and ELR_ELx become capabilities. So long as software adheres to RES0/1 this is backwards-compatible, but since EDK2 does not do so here it inadvertently enables capability-based exception delivery and return and thus, when run at EL2, gets stuck in a trap loop when taking its first interrupt, but works just fine at EL1. Fix this by setting all the RES1 fields in CPTR_EL2, following the pattern for CPACR_EL1's non-zero initial value (due to setting FPEN so as to not trap on SIMD/FP use), tested by running ArmVirtQemu-AARCH64 (DEBUG) on Morello QEMU with EL2 enabled.

* ArmPlatformPkg,MdePkg: Rename AARCH64 CPACR_CP_FULL_ACCESSJessica Clarke2024-11-141-3/+3
| | | | | | | | | | | | | | CP_FULL_ACCESS is a misnomer, we only enable access to SIMD/FP state, and although the register's mnemonic is CPACR_EL1, its full name is "Architectural Feature Access Control Register", with AArch64 having no coprocessors like AArch32 did, so the "CP" is also not appropriate. Rename it to show it's the default value we use on entry, and define it in terms of the existing CPACR_FPEN_FULL rather than a magic constant with the same value to more clearly document that fact. Also update comments to reflect all this (including the CPTR_EL2 case). Continuous-integration-options: PatchCheck.ignore-multi-package Signed-off-by: Jessica Clarke <jrtc27@jrtc27.com>
* ArmPlatformPkg: Document that we don't support HCR_EL2.E2H being setJessica Clarke2024-11-141-0/+2
| | | | | | | | | | | The existing code here predates its existence as it's assuming that CPTR_EL2 has the traditional layout rather than being like CPACR_EL1 (likely also true elsewhere for other registers), and the UEFI spec has nothing to say on the matter. One assumes the intent is that if you're in EL2 you're in EL2 proper, and it would be very strange to enter EDK2 with E2H set. Document this existing assumption.

* MdePkg: Move AsmMacroIoLib*.h from ArmPkgOliver Smith-Denny2024-09-127-7/+7
| | | | | | | | | | | | | | | | | | | AsmMacroIoLib.h and AsmMacroIoLibV8.h are used by the CompilerIntrinsicsLib, which is moving to MdePkg. These functions provide standard definitions for ARM/AARCH64 assembly code, respectively, and so are moved to the arch directories in MdePkg to avoid MdePkg having a dependency on ArmPkg. Now that the files are in Arm/ and AArch64/ directories, the filenames are changed to AsmMacroLib.h as we can distinguish the architecture from the path. AsmMacroIoLib.inc is unused and so is removed. Continuous-integration-options: PatchCheck.ignore-multi-package Signed-off-by: Oliver Smith-Denny <osde@linux.microsoft.com>
* ArmPlatformPkg: Initialize Serial Port Before WritingOliver Smith-Denny2024-08-281-0/+4
| | | | | | | | | | | | | | | | | PrePeiCore and Sec directly write the firmware version to the serial port. They relies on another component to initialize the serial port, however in certain configurations (such as release builds that don't use a DebugLib that initializes the serial port), the serial port can be uninitialized at this point, causing a crash when SerialPortWrite is called here. This patch updates PrePeiCore and Sec to call SerialPortInitialize before calling SerialPortWrite directly, which follows the pattern of other serial port writes. It is accepted to call the initialization routine multiple times, it is supposed to dump out if the serial port is already initialized. Signed-off-by: Oliver Smith-Denny <osde@linux.microsoft.com>
* ArmPlatformPkg: Clone PrePeiUniCore into SecArd Biesheuvel2024-08-0112-0/+891
| | | | | | | | | | | | PrePeiUniCore was already named rather awkwardly, but now that the UniCore bit has become redundant too, let's rename it in a way that conveys its purpose a bit better: Sec. This also matches what other architectures and platforms tend to provide. A straight rename would break all out-of-tree users, so clone it into a new module with a fresh GUID, giving users some time to update. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
* ArmPlatformPkg: remove unused Sec libraryRyan Harkin2016-02-0911-1042/+0
| | | | | | | | | | | The Sec library was built by the AARCH64 FVP models, but the binary was unused because it was part of a legacy booting strategy from before ARM Trusted Firmware came along.

* ArmPlatformPkg/Sec: fix return_from_exception code and commentArd Biesheuvel2015-12-142-17/+6
| | | | | | | | | | | | | | | | The return_from_exception implementation in Sec/Helper.S (the GCC version) deviates from the RVCT version, in a way that suggests that both may have been broken at some point, and that they weren't fixed in the same way nor at the same time. So bring the GCC version in line with the RVCT version, and at the same time, deobfuscate the comment.

| | | | | | | | | | The enter_monitor_world() function was trashing r0/r1/r2 registers and then was returning back to 'C'. The compiler might have used these registers in the C code. These new design prevents register corruptions. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@13060 6f19259b-4bc3-4df7-8a09-765794883524

It means stack_size must be added to the stack base. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12858 6f19259b-4bc3-4df7-8a09-765794883524
