We are able to compile CPP files for X64 using UDK2014 by using Visual Studio. How do we compile the same source for AARCH64? Appreciate the help! Thanks, Daniel

[PATCH 0/3] add ARM and AArch64 support

by Ard Biesheuvel

These patches have been in my personal queue for about two years, and have already been incorporated into the Ubuntu packaged version of sbsigntool. Patch #1 and #2 fixes some generic issues, and patch #3 introduces the ARM and AArch64 magic values in the PE/COFF header check, which is all that is needed to get sbsign to sign ARM images.

[edk2] [PATCH v4 0/3] support multiple PL061 gpio controllers

by Haojian Zhuang

Changelog: v4: * Use 64-bit value on PL061 register base address. * Use fallback to be compatible with current PcdPL061GpioBase value when platform gpio driver isn't present. * Remove the dependancy on PL061. Move the dependancy to platform gpio driver instead. v3: * Remove GPIO_PIN_MASK_HIGH_8BIT() and GPIO_PIN_MASK_LOW_8BIT(). * Avoid to use MmioAnd8() on updating GPIO DATA register, since PL061 could access each bit by specified register offset. * Add PLATFORM_GPIO_CONTROLLER structure in embedded gpio. * Support multiple PL061 gpio controllers in one platform. v2: * Append the patch to fix gpio pin mask macro.

Quiry of EFI_EXT_SCSI_PASS_THRU_PROTOCOL, supporting sas disk for hisilicon hip06

by Zhangfei Gao

We are planning to support sas disk for hisilicon hip06. Want to double check whether using EFI_EXT_SCSI_PASS_THRU_PROTOCOL is right direction? Originally we would like directly use BLOCK IO, which need hack scsi cmd (cdb) and port lots of code. Happen to find the scsi protocol is somehow realized in ./MdePkg/Library/UefiScsiLib/UefiScsiLib.c, so switch to EFI_EXT_SCSI_PASS_THRU_PROTOCOL. By the way, I got one problem. The API of EFI_EXT_SCSI_PASS_THRU_PROTOCOL can not be called by MdeModulePkg/Bus/Scsi/ScsiBusDxe/ScsiBus.c. While EFI_NOT_FOUND EFIERR (14) is returned. Status = ScsiBusDev->ExtScsiInterface->GetNextTargetLun (ScsiBusDev->ExtScsiInterface, &TargetId, &Lun); Any suggestion? Thanks Zhangfei

[PATCH 1/2] ArmPkg: Bds: check path first for supporting fs

by Haojian Zhuang

BdsFileSystemSupport() checks Handle first before validating device path of file. There's the potential issue at here. BdsConnectAndUpdateDevicePath() will skip to locate handle if it's file or memory mapped. Then BdsFileSystemSupport() tries to use the invalid Handle when it's not file path in file system. Now check the device path first. If it's not file path in file system, return directly.

[PATCH v2 5/5] Platforms/ARM: Add optional GICv3 with v2 Legacy support

by Ryan Harkin

GICv3 with v2 legacy support was removed, but this patch adds it back in conditionally.

[PATCH 0/5] Copy commits from EDK2

by Ryan Harkin

Before removing Juno and FVP from ArmPlatformPkg, it has been noted that we should copy latest developments from EDK2 to OpenPlatformPkg to make sure there is not functionalilty lost. With the patches I manually copied over, I tried to keep the original author using the "--author" param, hopefully this translates across git send-email. The following 4 patches are copied from EDK2: [PATCH 1/5] ArmPlatformPkg/FVP: use 'auto' alignment and FIXED [PATCH 2/5] ArmPlatformPkg: Link separated VarCheckUefiLib NULL class [PATCH 3/5] ArmPlatformPkg/FVP: unify support for Foundation and Base [PATCH 4/5] ArmVExpressPkg/ArmVExpress-FVP-AArch64: run GICv3 in v3 And this one it not copied from EDK2: [PATCH 5/5] Platforms/ARM: Add optional GICv3 with v2 Legacy support

Shell BCFG command - adding option data

by Ryan Harkin

Hello all, I'm using Shell.efi, a magic binary that is included in my aarch64 FVP binary. I'm trying to manipulate boot options using the BCFG command. And I've failed to work out how to set optional data. Before I clone ShellPkg and trawl through the code, I thought I'd post here and see if someone can tell me what's going wrong. First step, I created a boot option to run Shell.efi using the Intel BDS menu system. Thanks to Lazlo fixing cursor key support ;-) I added some simple optional data, "1 2 3 4". Next, I deleted all the other boot entries that were created by default, leaving only my new boot option. I created the option again, without optional data, giving it the description "xxxxxxxx" instead of "Shell.efi" (they're the same length) and here's what I see: Then I started the first new Shell.efi option. It gives an error that is hardly unexpected: '2' is not recognized as an internal or external command, operable program, or script file. So I ask bcfg to list my boot options and it says: Shell> bcfg boot dump Option: 00. Variable: Boot0006 Desc - Shell.efi DevPath - Fv(87940482-FC81-41C3-87E6-399CF85AC8A0)/\Shell.efi Optional- N Option: 01. Variable: Boot0000 Desc - xxxxxxxxx DevPath - Fv(87940482-FC81-41C3-87E6-399CF85AC8A0)/\Shell.efi Optional- N It claims there is no optional data. Hmmmm. So I dumped the value of variables Boot0006 and Boot0000 and I can see the optional data in there: Shell> setvar Boot0006 8BE4DF61-93CA-11D2-AA0D-00E098032B8C - Boot0006 - 005C Bytes 01 00 00 00 32 00 53 00 68 00 65 00 6C 00 6C 00 2E 00 65 00 66 00 69 00 00 00 04 07 14 00 82 04 94 87 81 FC C3 41 87 E6 39 9C F8 5A C8 A0 04 04 1A 00 5C 00 53 00 68 00 65 00 6C 00 6C 00 2E 00 65 00 66 00 69 00 00 00 7F FF 04 00 31 00 20 00 32 00 20 00 33 00 20 00 34 00 00 00 Shell> setvar Boot0000 8BE4DF61-93CA-11D2-AA0D-00E098032B8C - Boot0000 - 004C Bytes 01 00 00 00 32 00 78 00 78 00 78 00 78 00 78 00 78 00 78 00 78 00 78 00 00 00 04 07 14 00 82 04 94 87 81 FC C3 41 87 E6 39 9C F8 5A C8 A0 04 04 1A 00 5C 00 53 00 68 00 65 00 6C 00 6C 00 2E 00 65 00 66 00 69 00 00 00 7F FF 04 00 Shell> I started out this investigation because I was trying to add a boot option from the Shell command line and I can't work out how to add optional data: Shell> bcfg boot add 0 fs0:\Shell.efi "zzzzzzzzz" Target = 0001. bcfg: Add Boot0001 as 0 Shell> bcfg boot dump Option: 00.

I also tried setting the optional data at the same time as creating the boot option, but that fails in the same way: Shell> bcfg boot add 0 fs0:\Shell.efi "Shell" -opt 0 1 2 3 So, am I doing something wrong or is BCFG buggy?? I'm off to look at the code, because I think there's at least one bug... Regards, Ryan.

[PATCH 0/2] ArmPlatformPkg: Remove FVP and Juno

by Ryan Harkin

ARM Ltd Platform support is migrating to use OpenPlatformPkg [1]. Currently, Juno and FVP exist both in EDK2's ArmPlatformPkg and in OpenPlatformPkg. And they are starting to diverge, with OpenPlatformPkg being the most up-to-date with current developments. To prevent this divergence, remove the .dsc and .fdf files from ArmPlatformPkg and leave OpenPlatformPkg as the master. We can't remove ArmJuno.dec yet because ACPI still uses it to set the include path to ArmPlatform.h.
