* ArmPkg/ArmLib: remove indirection layer from timer register accessorsArd Biesheuvel2017-01-203-141/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | The generic timer support libraries call the actual system register accessor function via a single pair of functions ArmArchTimerReadReg() and ArmArchTimerWriteReg(), which take an enum argument to identify the register, and return output values by pointer reference. Since these functions are never called with a non-immediate argument, we can simply replace each invocation with the underlying system register accessor instead. This is mostly functionally equivalent, with the exception of the bounds check for the enum (which is pointless given the fact that we never pass a variable), the check for the presence of the architected timer (which only makes sense for ARMv7, but is highly unlikely to vary between platforms that are similar enough to run the same firmware image), and a check for enum values that refer to the HYP view of the timer, which we never referred to anywhere in the code in the first place. So get rid of the middle man, and update the ArmGenericTimerPhyCounterLib and ArmGenericTimerVirtCounterLib implementations to call the system register accessors directly.

* ArmPkg/ArmMmuLib: avoid type promotion in TCR_EL1 assignmentArd Biesheuvel2016-07-131-78/+62
| | | | | | | | | | | | | | | | | | | | | | Commit fafb7e9c110e ("ArmPkg: correct TTBR1_EL1 settings in TCR_EL1") introduced a symbolic constant TCR_TG1_4KB which resolves to (2 << 30), and ORs it into the value to be written into TCR_EL1 (if executing at EL1). Since the constant is implicitly typed as signed int, and has the sign bit set, the promotion that occurs when casting to UINT64 results in a TCR value that has bits [63:32] all set, which includes mostly RES0 bits but also the TBIn, AS and IPS fields. So explicitly redefine all TCR related constants as 'unsigned long' types, using the UL suffix. To avoid confusion in the future, the inappropriately named VTCR_EL23_xxx constants have the leading V removed, and the actual VTCR_EL2 related constants are dropped, given that we never configure stage 2 translation in UEFI.

* ArmPkg/ArmPlatformPkg: position vectors relative to baseMark Rutland2015-11-191-0/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | We currently rely on .align directives to ensure that each exception vector entry is the appropriate offset from the vector base address. This is slightly fragile, as were an entry to become too large (greater than 32 A64 instructions), all following entries would be silently shifted until they meet the next alignment boundary. Thus we might execute the wrong code in response to an exception. To prevent this, introduce a new macro, VECTOR_ENTRY, that uses .org directives to position each entry at the precise required offset from the base of a vector. A vector entry which is too large will trigger a build failure rather than a runtime failure which is difficult to debug. For consistency, the base and end of each vector is similarly annotated, with VECTOR_BASE and VECTOR_END, which provide the necessary alignment and symbol exports. The now redundant directives and labels are removed.

* ArmPkg: correct TTBR1_EL1 settings in TCR_EL1Mark Rutland2015-11-191-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | As EDK2 runs in an idmap, we do not use TTBR1_EL1, nor do we configure it. TTBR1_EL1 may contain UNKNOWN values if it is not programmed since reset. Prior to enabling the MMU, we do not set TCR_EL1.EPD1, and hence the CPU may make page table walks via TTBR1_EL1 at any time, potentially using UNKNOWN values. This can result in a number of potential problems (e.g. the CPU may load from MMIO registers as part of a page table walk). Additionally, in the presence of Cortex-A57 erratum #822227, we must program TCR_EL1.TG1 == 0b1x (e.g. 4KB granule) regardless of the value of TCR_EL1.EPD1, to ensure that EDK2 can make forward progress under a hypervisor which makes use of PAR_EL1. This patch ensures that we program TCR_EL1.EPD1 and TCR_EL1.TG1 as above to avoid these issues. TCR_EL1.TG1 is set to 4K for all targets, as any CPU capable of running EDK2 must support this granule, and given TCR_EL1.EPD1, programming the field is not detrimental in the absence of the erratum.

This is relevant for things like coherent DMA and virtualization (where a guest may migrate to another core) but in general, since UEFI on ARM is mostly used in a context where the secure firmware and possibly a secure OS are already up and running, it is best to refrain from using any non-shareable mappings.
