[RFC] first view: armv7 Linux early_ioremap

by Leif Lindholm

Hi all, This is my first, monolithic, stab at an early_ioremap for ARMv7 - taken straight from the head of http://git.linaro.org/gitweb?p=people/leiflindholm/linux-uefi-runtime-servi… I'll be cleaning up, splitting up, documenting and see if I can get it working on non-LPAE in time, and then send it upstream later this week. Early reviewing would be much appreciated. / Leif

Re: Possible race condition in multi-core EDK2

by Roy Franz

Hi Oliver, Sorry for the missing information. I am using version 7.1.63 of the A15 fast model. I'm using the ArmVExpress-RTSM-A15_MPCore.dsc dsc file,and building against the linaro-tracking-2013.05 branch of the uefi-next repository. I have been making some changes, mostly debug related. I had made the following changes to the DSC file: gArmPlatformTokenSpaceGuid.PcdCoreCount|1 gArmPlatformTokenSpaceGuid.PcdSendSgiToBringUpSecondaryCores|FALSE This was running fine on a single core until I started removing some debug prints.

[PATCH 0/1] Removing GIC driver from Arndale BSP

by Ryan Harkin

These two patches will remove the GIC driver from the Arndale BSP, instead using the official GIC driver from the upstream tree: [PATCH 1/2] Samsung/Arndale: remove GIC400 driver [PATCH 2/2] ArmPkg/PL390Gic: remove ArmPlatformLib from inf file I've already sent the second patch to Olivier for review, but as far as I can see, ArmPlatformLib is incuded in the PL390 sec lib, but it isn't needed. Including it when booting on Arndale hangs the board. I'm guessing there are two issues: 1) if it isn't needed, we can remove it 2) but it shouldn't crash Arndale if it is included, so Arndale is most likely doing something wrong and we should probably work out what that is. However, the general act of replacing Arndale's clone of the GIC driver seems safe. Arndale appears to have simply cloned an old version of the driver without modification. However, a couple of the bit masks may be different, so perhaps there is an underlying problem that I have not discovered? Hence, a review by a few other people is really important. Regards, Ryan.

Possible race condition in multi-core EDK2

by Roy Franz

I've been working with the DEBUG build of EDK2, and thought I had changed the configuration to be 'proper' for a single core, and it ran fine on a single core simulation. As I started removing debug prints, I started getting simulator seg faults. I confirmed that the difference between running and crashing versions were simply debug prints. Changing the simulation to simulator 2 cores resolved the problem. I suspect that there may be a race condition or some other multi-core detection bug that causes this crash. I don't plan to investigate this further at this point - just wanted to report this as I was surprised to find that a debug print being removed would cause the simulator to crash. Roy

uefi-build.sh - bash completion

by Ryan Harkin

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.

I have no specific code that was using the IS_PRIMARY_CORE() macro, so these patches will not give an example of how you deal with those changes, but Olivier's original patch should help a lot there.

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.

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.

boot Ubuntu using PXE from U-Boot on the Samsung XE303C12-A01US Chromebook

by Mario

Hello. I'm trying to boot Ubuntu using PXE from U-Boot on the Samsung XE303C12-A01US Chromebook. I would like to understand better the point 5 of the tutorial here : https://wiki.linaro.org/Boards/Arndale/Setup/PXEBoot it says : "At the u-boot prompt, set the environmental variables "serverip" and "ipaddr" as per the board and host PC configuration. Now set the following environmental variables as mentioned..." the problem is that the Samsung XE303C12-A01US does not have a serial port and I can't stop the u-boot booting and set the enviromental variables manually. I would like to know how can I embed them inside u-boot. Also because there is not a configuration file like boot.cmd/boot.scr like there is on the pandaboard that can be used to pass the parameters. Thanks. -- Mario.

OMAP4 PandaBoard 4430 vs PandaBoardES 4460

by Péter Ujfalusi

Hi, First of all I'm not sure if this is the right list to post this, but I thought boot-architecture might be the best list to post. Currently we have one hwpack for PandaBoard4430 and PandaBoardES 4460 which means that when we install the hwpack on PandaBoardES the kernel thinks it is running on PandaBoard 4430. However there is a HW difference between the two boards: Audio routing is different (for capture path). Also the hdmi pin muxing need to be different (according to the DTS files). I can see two ways of dealing with the different versions: 1. create separate hwpacks for the revisions where only the included DTB file is different: PandaBoard 4430: omap4-panda.dtb PandaBoardES: omap4-panda-es.dtb 2. Or to have single hwpack for Panda: With the included patch in u-boot Include both omap4-panda.dtb and omap4-panda-es.dtb files to the boot partition. Modify the boot.txt to load different dtb based on the board: if is_pandaES; then setenv bootcmd "fatload mmc 0:1 0x80200000 uImage; fatload mmc 0:1 0x81600000 uInitrd; fatload mmc 0:1 0x815f0000 omap4-panda-es.dtb; bootm 0x80200000 0x81600000 0x815f0000"; else setenv bootcmd "fatload mmc 0:1 0x80200000 uImage; fatload mmc 0:1 0x81600000 uInitrd; fatload mmc 0:1 0x815f0000 omap4-panda.dtb; bootm 0x80200000 0x81600000 0x815f0000"; fi; For audio we need to tell the difference between the two revision and this is done via different DTB blob. Thank you, Péter

Planned maintenance - lists.linaro.org

by IT Services

Hello You are receiving this email because you are subscribed to one or more mailing lists provided by the lists.linaro.org server. IT Services are announcing planned maintenance for this server scheduled for *Friday 15th March 2013, starting at 2pm GMT*. The purpose of the work is to move the service to another server. There will be some disruption during this maintenance. In order to ensure that you do not accidentally try to use the service while it is being moved, the current server will be shut down at 2pm. A further email will be sent on Friday afternoon to confirm that the migration of the service is completed. However, due to the way servers are found, it may take a while before your computer is able to connect to the relocated service. After the old server has been shut down, email sent to any of the lists will be queued, but it is possible that the sending server will still trying to deliver the email to the old server rather than the new one when it is started. It is therefore *strongly* recommended that you do not send any email to an @lists.linaro.org email address until you can connect to the new service, which you will be able to test by trying to use a web browser to connect to http://lists.linaro.org after you receive the email confirming that the migration has been completed. Since the old service will be shut down, if you are able to connect, you can be sure you have connected to the new service. If by Monday you are still unable to connect to the service or you are not able to send email to an @lists.linaro.org email address, please send an email to its(a)linaro.org. Thank you.

[PATCH] MdeModulePkg/PartitionDxe: hack MBR unique signature to zero

by Ryan Harkin

This is a hack and is not intended to go upstream, but will be useful for Linaro's short term goals. Linaro's development boards use SD cards, currently we have a problem where each unique SD card has a different UUID when created with linaro-media-create / linaro-android-media create. This means that no one Boot Device configuration can boot Linaro images without some manual intervention from the user. This hack will zero the signature (UUID) read from the card meaning that all SD cards will appear to be the same card.

[PATCH] Samsung/Arndale: use Linaro default config

by Ryan Harkin

The attached patch will change the default config for the Arndale board so that it boots into a Linaro SD card image. Problem is that a bug [1] prevents the Arndale board booting from a linaro-media-create'd image, so this patch can only sensibly applied after that bug is fixed.
