* ArmPlatformPkg: Dynamic flash variable baseSami Mujawar2020-10-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Some virtual machine managers like kvmtool can relocate the devices in the system memory map. The information about the devices location in memory is described in the device tree. Therefore, the CFI memory region and the associated Non volatile storage variables need to be adjusted accordingly. To support such use cases the non-volatile storage variable base PCD PcdFlashNvStorageVariableBase has been defined as a dynamic PCD. The NOR flash driver was using the Flash non-volatile storage variable base PCD as a fixed PCD, thereby preventing runtime resolution of the variable base address. Therefore update the NOR flash driver to load the PCD using PcdGet32 instead of FixedPcdGet32.

* ArmPlatformPkg/PrePi: replace set/way cache ops with by-VA onesArd Biesheuvel2020-03-053-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 UEFI memory region by virtual address, which is the only memory region we will be touching with the caches and MMU both disabled and enabled. (This 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.)

* ArmPlatformPkg: convert LFs to CRLF, expand hard TABsLaszlo Ersek2020-03-041-328/+328
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We're going to switch the internal line terminators globally to LF at some point, but until then, let's use CRLF consistently. Convert source files with LFs in them to CRLF, using "unix2dos". "git show -b" prints no code changes for this patch. (I collected all the file name suffixes in this package, with: $ git ls-files -- $PACKAGE | rev | cut -f 1 -d . | sort -u | rev I eliminated those suffixes that didn't stand for text files, then blanket-converted the rest with unix2dos. Finally, picked up the actual changes with git-add.) At the same time, the following file had to undergo TAB expansion: ArmPlatformPkg/Scripts/Ds5/profile.py I used "expand -t 4", conforming to the Indentation section of PEP-8 <https://www.python.org/dev/peps/pep-0008/#indentation>. Both the CRLF conversion and the TAB expansion are motivated by "PatchCheck.py". "PatchCheck.py" is also the reason why CRLF conversion and TAB expansion have to happen in the same patch.

This LcdHwLib implementation should be suitable for those platforms that implement ARM Mali DP500/DP550/DP650 replacing PL111/HDLCD. Only graphics layer of the ARM Mali DP is configured for rendering the RGB/BGR format frame buffer to satisfy the UEFI GOP requirements Other layers e.g. video layers are not configured.

* ArmPlatformPkg: Reserving framebuffer at buildGirish Pathak2018-04-231-0/+5
| | | | | | | | | | | | | | | | | | | | | | | Currently framebuffer memory is either reserved in special VRAM or dynamically allocated using boot services memory allocation functions. When allocated using boot services calls the memory has to be allocated as EfiBootServicesData. Unfortunately failures have been seen with this case. There is also an unfortunate lack of control on the placement of the framebuffer. This change introduces two PCDs, PcdArmLcdFrameBufferBase and PcdArmLcdFrameBufferSize which enable build time reservation of the framebuffer, avoiding the need to allocate dynamically. This allows the framebuffer to appear as "I/O memory" outside of the normal RAM map, which is similar to the "VRAM" case. This change has no impact on current code, only enables the option of build time reservation of framebuffers.

* ArmPlatformPkg: PCD to swap red/blue format for HDLCDGirish Pathak2018-04-233-2/+16
| | | | | | | | | | | | | | | | | | | This change adds a new PCD PcdArmHdlcdSwapBlueRedSelect to swap values for HDLCD RED_SELECT and BLUE_SELECT registers on platforms where blue and red hardware lines are swapped. If set to TRUE in the platform dsc, HDLCD library will swap the values while setting RED_SELECT and BLUE_SELECT registers. The default value of the PCD is FALSE. NOTE: The motive for this is that a discrepancy in the Red/Blue lines exists between some VersatileExpress platforms. Rather than have divergent code, this build switch allows a simple, pragmatic solution.

* ArmPlatformPkg: Add PCD to select pixel formatGirish Pathak2018-04-233-38/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current HDLCD and PL111 platform libraries do not support display modes with PixelBlueGreenRedReserved8BitPerColor format, i.e. because of historical confusion, they do not support the UEFI default PixelBlueGreenRedReserved8BitPerColor format In LcdPlatformLib for PL111, LcdPlatformQueryMode returns the pixel format as PixelRedGreenBlueReserved8BitPerColor which is wrong, because that does not match the display controller's pixel format which is set to BGR in PL111Lcd LcdHwLib. Also it is not possible to configure pixel format as RGB/BGR for the display modes for a platform at build time. This change adds PcdGopPixelFormat to configure pixel format as PixelRedGreenBlueReserved8BitPerColor or PixelBlueGreenRedReserved8BitPerColor or PixelBitMask. With this change, pixel format can be selected in the platform specific .dsc file for all supported display modes. Support for PixelBitMask is not implemented in PL111 or HDLCD LcdHwLib libraries, hence HDLCD and PL111 platform libraries will return error EFI_UNSUPPORTED if PcdGopPixelFormat is set to PixelBitMask. Indeed, it is not clear what selecting PixelBitMask might mean, but the option is allowed as it might suit a custom platform.
