Hey all, After my chat with Leif chat on Thurs, one thing I thought about was bash completion for uefi-build.sh. Turns out it's quite easy! I just pushed this commit to uefi-tools.git [1]. It's quite dumb in that you can autocomplete "DEBUG" or "RELEASE" even without the "-b" parameter, but hey, it makes my life easier :-) Cheers, Ryan. commit dc3ba99d46ecb87c529a475d5ff6b840cd2f7c8d Author: Ryan Harkin <ryan.harkin(a)linaro.org> Date: Tue Jun 11 13:00:12 2013 +0100 uefi-build: add bash completion script Copy this script into the bash completion directory to easy entering parameters: $ sudo cp uefi-build.sh.bash_completion \ /etc/bash_completion.d/uefi-build.sh Signed-off-by: Ryan Harkin <ryan.harkin(a)linaro.org> diff --git a/uefi-build.sh.bash_completion b/uefi-build.sh.bash_completion new file mode 100644 index 0000000..f0a5305 --- /dev/null +++ b/uefi-build.sh.bash_completion @@ -0,0 +1,24 @@ +# bash completion for uefi-build.sh +# copy this file to /etc/bash_completion.d/uefi-build.s + +have uefi-build.sh && +_uefi-build.sh() +{ + local cur prev + + COMPREPLY=() + _get_comp_words_by_ref -n = cur + + _expand || return 0 + + COMPREPLY=( $( compgen -W '--help -b --build RELEASE DEBUG a5 a9 tc1 tc2 panda origen arndale rtsm_a9x4 rtsm_a15x1 rtsm_a15mpcore rtsm_aarch6 +} && +complete -F _uefi-build.sh uefi-build.sh + +# Local variables: +# mode: shell-script +# sh-basic-offset: 4 +# sh-indent-comment: t +# indent-tabs-mode: nil +# End: +# ex: ts=4 sw=4 et filetype=sh [1] http://git.linaro.org/gitweb?p=arm/uefi/uefi-tools.git;a=summary

[PATCH 0/1] How to fix your ARM UEFI BSP to work with the latest upstream Tianocore code

by Ryan Harkin

[PATCH 1/2] TC1: Fix TC1 build for latest upstream changes [PATCH 2/2] VEA5: Fix A5 build for latest upstream changes The two platforms are relatively simple to fix because they follow the TC2 and A9 BSPs very closely. Perhaps close enough to some more code to be moved to common areas ;-) These examples will show you the simple steps you will need to take to get your BSP working. However, your BSP may be using old functionality that my BSPs were not. The main change to watch out for is the deletion of the macro IS_PRIMARY_CORE() which has been replaced with a function that the BSP must provide. The change came about with this commit: -------------------------------------------------------------------------------- commit bebda7ceec3d3024c76b3c2ed0c9b4e502a13d61 Author: oliviermartin <oliviermartin@6f19259b-4bc3-4df7-8a09-765794883524> Date: Fri May 10 12:41:27 2013 +0000 ArmPlatformPkg/ArmPlatformLib: Added support for ArmPlatformIsPrimaryCore() Checking if a core if the primary/boot core used to be done with the macro IS_PRIMARY_CORE(). Some platforms exposes configuration registers to change the primary core. Replacing the macro IS_PRIMARY_CORE() by ArmPlatformIsPrimaryCore() allows some flexibility in the way to check the primary core.

linaro-uefi-2013.06-rc1 is out

by Ryan Harkin

Hello UEFI folks, I spent the day with Leif going through maintainer stuff and together we produced the 2013.06 iteration of the Linaro UEFI tree [1]. Highlights include: - A5, TC1, Panda, Origen and Arndale no longer build (I will be fixing A5 and TC1 as part of -rc2, unless something else urgent comes in and needs an -rc2) - The -menu and -local-fdt topics have been merged into one -bds topic to simplify upstreaming, reviewing and merging - All topics are rebased to the latest Tianocore upstream code - Some of our patches have made it upstream - yay! - and thus have been removed from our topic branches - There are more patches that we think are ready to go upstream now. I'll start this after -rc2 Regards, Ryan. [1] https://git.linaro.org/gitweb?p=arm/uefi/uefi-next.git;a=summary

Yes, but you shouldn't even need to do that. I just looked at the LinuxLoader code, in particular the UEFI FDT code, and I've noticed that the reserved regions should already be set up. Look in ArmPkg/Library/BdsLib/BdsLinuxFdt.c, about line 420. The function PrepareFdt() retrieves the UEFI memory map and calls fdt_add_mem_rsv() for each region. It does use the function IsLinuxReservedRegion() to filter the regions, so if SMBIOS uses a different region type then you'll need to add that type to the list. So, if I'm correct, it should be sufficient to merely enable SMBIOS support in UEFI and the kernel will automatically mark the SMBIOS region as reserved. You can verify this by adding "memblock=debug" to the kernel command line and looking at the kernel boot output. You'll see something like this: memblock_reserve: [0x00000000008400-0x0000000042e98c] arm_memblock_init+0x4c/0x150 memblock_reserve: [0x00000004000000-0x0000000452f400] arm_memblock_init+0xcc/0x150 memblock_reserve: [0x00000000004000-0x00000000008000] arm_memblock_init+0xf0/0x150 memblock_reserve: [0x00000004530000-0x00000004537350] arm_dt_memblock_reserve+0x30/0xb0 MEMBLOCK configuration: memory size = 0x8000000 reserved size = 0x960cdc memory.cnt = 0x1 memory[0x0] [0x00000000000000-0x00000007ffffff], 0x8000000 bytes reserved.cnt = 0x4 reserved[0x0] [0x00000000004000-0x00000000007fff], 0x4000 bytes reserved[0x1] [0x00000000008400-0x0000000042e98b], 0x42658c bytes reserved[0x2] [0x00000004000000-0x0000000452f3ff], 0x52f400 bytes reserved[0x3] [0x00000004530000-0x0000000453734f], 0x7350 bytes Memory policy: ECC disabled, Data cache writeback memblock_reserve: [0x00000007fff000-0x00000008000000] memblock_alloc_base_nid+0x68/0x84 memblock_reserve: [0x00000007ffe000-0x00000007fff000] memblock_alloc_base_nid+0x68/0x84 memblock_reserve: [0x00000007ffdf10-0x00000007ffe000] memblock_alloc_base_nid+0x68/0x84 memblock_reserve: [0x00000007ffc000-0x00000007ffd000] memblock_alloc_base_nid+0x68/0x84 memblock_reserve: [0x00000007ffb000-0x00000007ffc000] memblock_alloc_base_nid+0x68/0x84 memblock_reserve: [0x00000007ffa000-0x00000007ffb000] memblock_alloc_base_nid+0x68/0x84 Note: this only works with the UEFI LinuxLoader. The GRUB code doesn't currently add the UEFI reserved regions to the FDT reserved map. g.

EFI_STUB notes

by Grant Likely

Hi Roy, Here are some very quick notes on what I found on writing UEFI applications. I found a library called "gnuefi" which allows building EFI applications apart from the Tianocore build tree. It looks interesting, but has not been ported to ARM. I don't yet know if it is worthwhile pursuing. http://gnu-efi.sourceforge.net/ As mentioned, the Linux kernel has an EFI stub already. I could tell you which files to look at, but really just doing a "git grep EFI_STUB" in the kernel tree will show you all the files that you need to care about. :-) You'll need to figure out how to get a UEFI PE-COFF header into the LInux kernel zImage wrapper. It shouldn't be too hard. You'll need to look at the startup code in arch/arm/boot/compressed/head.S. The PE-COFF header will need to go somewhere after the start: label. You should be able to see the existing LInux kernel "header" (not much of a header, more of a magic number) about 10 lines down from the start label. That's all I can write at the moment. We can talk more tomorrow. g.

ARMv7-A UEFI runtime services support in Linux

by Leif Lindholm

Terse information, more engineering notes than documentation, and links to sources can be found at: https://wiki.linaro.org/LEG/Engineering/Kernel/UEFI/RuntimeServices Contains a few known bugs, and will need some fundamental discussions/reengineering, but lets us start experimenting. / Leif

PXE for arndale

by Rony Nandy

To boot linux kernel using TFTP in Arndale. Following is the steps: 1. Apply the patches 13.03 branch. (on top of Olivers Ethernet patches,If Olivier's patches doesn't apply, then do it manually) 2. Compile and boot as usual. 3. Wait till USB initialization and then do as shown below: The default boot selection will start in 1 seconds UsbEnumeratePort: Device Connect/Disconnect Normally UsbEnumeratePort: Device Connect/Disconnect Normally UsbEnumeratePort: Device Connect/Disconnect Normally EhcExecTransfer: transfer failed with 8 EhcControlTransfer: error - Device Error, transfer - 8 0x9F6BDA90: Allocate pNicDevice, 792 bytes 0x9F4DCD10: Allocated timer Installed: gEfiCallerIdGuid on 0x9F4DE390 Installed: gEfiSimpleNetworkProtocolGuid on 0x9F4DE390 MnpSyncSendPacket: No network cable detected.
