2020-03-04ArmPlatformPkg/PrePeiCore: replace set/way cache ops with by-VA onesArd Biesheuvel1-0/+1
Cache maintenance operations by set/way are only intended to be used in the context of on/offlining a core, while it has been taken out of the coherency domain. Any use intended to ensure that the contents of the cache have made it to main memory is unreliable, since cacheline migration and non-architected system caches may cause these contents to linger elsewhere, without being visible in main memory once the MMU and caches are disabled. In KVM on Linux, there are horrid hacks in place to ensure that such set/way operations are trapped, and replaced with a single by-VA clean/invalidate of the entire guest VA space once the MMU state changes, which can be costly, and is unnecessary if we manage the caches a bit more carefully, and perform maintenance by virtual address only. So let's get rid of the call to ArmInvalidateDataCache () in the PrePeiCore startup code, and instead, invalidate the temporary RAM region by virtual address, which is the only memory region we will be touching with the caches and MMU both disabled and enabled, which will lead to data corruption if data written with the MMU off is shadowed by clean, stale cachelines that stick around when the MMU is enabled again.

2020-01-14ArmPlatformPkg/PrePeiCore: enable VFP at startupArd Biesheuvel1-0/+1
While the alternative PEI-less SEC implementation in PrePi already takes the EnableVFP PCD into account, the PrePeiCore code does not, and so we may end up triggering synchronous exception when code attempts to use FP or SIMD registers, which is permitted on AARCH64 by the spec. So enable the VFP as early as feasible if the associated PCD is set. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Reviewed-by: Leif Lindholm <leif.lindholm@linaro.org>
2019-07-23ArmPlatformPkg: list module-internal header files in INF [Sources]Laszlo Ersek1-0/+1
The BaseTools build feature introduced for TianoCore#1804 / in commit 1fa6699e6cd4 ("BaseTools: Add a checking for Sources section in INF file", 2019-06-10) logs some (non-fatal) warnings about unlisted internal header files. List those files explicitly. Note: header files are added in lexicographical order only if the underlying INF file already keeps the [Sources] and [LibraryClasses] sections in lexicographical order. Otherwise, header files are added in rough "logical" order.

2017-11-09ArmPlatformPkg/PrePeiCore: seed temporary stack before entering PEI coreArd Biesheuvel1-0/+2
DEBUG builds of PEI code will print a diagnostic message regarding the utilization of temporary RAM before switching to permanent RAM. For example, Total temporary memory: 16352 bytes. temporary memory stack ever used: 4820 bytes. temporary memory heap used for HobList: 4720 bytes. Tracking stack utilization like this requires the stack to be seeded with a known magic value, and this needs to occur before entering C code, given that it uses the stack. Currently, only Nt32Pkg appears to implement this feature, but it is useful nonetheless, so let's wire it up for PrePeiCore.

These PCDs by default use the ClusterId and CoreId to identify the core. And the primary core is defined as the ClusetrId=0 and CoreId=0. The helper macros are: IS_PRIMARY_CORE(MpId), GET_CORE_ID(MpId), GET_CLUSTER_ID(MpId), GET_CORE_POS(MpId), PRIMARY_CORE_ID. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12412 6f19259b-4bc3-4df7-8a09-765794883524

2011-07-06ArmPlatformPkg: Remove PcdStandalone from Sec module and Introduce ↵oliviermartin1-2/+4
ArmPlatformSecExtraAction() The PcdStandalone is a PCD ARM Ltd uses to make the difference between a standalone UEFI (boot from cold boot to Boot Manager without user intervention) and a Debug UEFI firmware (the firmware engineer has to copy the Normale World image into the DRAM to enable his/her firmware). By coping the firmware into DRAM in the non standalone version it is much faster than reflashing the NOR Flash after each build. ArmPlatformSecExtraAction() function is called just before the Sec module jump to normal world. The platform firmware can run extra actions at this stage. The 'ARM Standalone' concept has moved to the implementation of ArmPlatformSecExtraAction() for the ARM development boards (in ArmPlatformPkg/Library/DebugSecExtraActionLib).
