You could have multiple ROMs, but the most common thing is to just have a single FD. FV is a Firmware Volume. Basically a simple Flash Filesystem that allows files, named by GUIDs to be discovered. EFI is a collection of relocatable PE/COFF images, and in general an INF file (no for a library) in your project maps to a PE/COFF file getting generated. It can vary by compiler, but it is common for the *.dll file to be the native image with the debug info. So that is the file you want to load symbols for. There are various schemes on how to do this. Some platforms print out debug messages that map into the commands you need to load symbols. Some platforms have scripts that can load symbols. Sorry I don't remember the latest recommendation on which scheme to use for your platform? Try looking at the *.Fv.map file as I think it has info about how to load symbols. You would need a script to convert this into some format the DS-5 understands. Maybe the scripts in https://svn.code.sf.net/p/edk2/code/trunk/edk2/ArmPlatformPkg/Scripts/Ds5/ are what you are looking for?

Aarch64 patches for uefi-next.git

by Ryan Harkin

Hi Steven, Please find attached two patches used for aarch64 work. Each patch goes into a different topic branch in the end, not in the linaro-topic-fvp branch as we discussed earlier. Still, they are quite simple, so shouldn't cause much of a problem. 0001-tools_def-AARCH64-use-CROSS_COMPILE-variable.patch The above patch goes into linaro-topic-misc. 0002-FVP-Add-support-for-EDK2_USE_ANDROID_CONFIG-build-pa.patch The above patch goes into linaro-topic-fvp. Please let me know if these cause you any problems, but it would be good to get them into uefi.git for the -rc4 and the -03 release respin. You can also pull both patches/branches from my tree: https://git.linaro.org/gitweb?p=people/ryanharkin/uefi-next.git;a=summary Thanks, Ryan.

If you mean that there are two command lines to parse for the EFI_LOADED_IMAGE (one for shell/gummiboot), surely there is a handle in there to identify the "current" one. / Leif

The way that can be resolved is: - FDT present? - Commandline present in FDT chosen node? - Yes - Use that. - No - EFI_LOADED_IMAGE command line present? - Yes - Use that. - No - Fail miserably. / Leif

Yes, both my implementation and the x86 implementation get the command line from the EFI_LOADED_IMAGE protocol, and do conversion from UCS-2 (I think) to ASCII/UTF-8 to pass to the kernel.

OK. So we push the actual error condition of missing tree down to stub?

This would be my preference. > The other option would be to pass the command line via the LoadOptions > from the EFI_LOADED_IMAGE protocol. I believe that is what Roy's > patches currently rely on for getting a command line. Since the current code doesn't UEFI-wise "load" the stub image, we'd effectively need to reverse-reconstruct GRUB's runtime environment, which I really wouldn't like. / Leif

uefi stub + grub

by Leif Lindholm

Hi guys, I've been looking at the patches Matthew Garrett wrote for loading a UEFI stub kernel through GRUB, and noticed one thing that may require updates to the stub code: it uses GRUB to load the initrd. Doing this of course means the initrd does not need to go into the EFI System Partition, which is a lot nicer from the distros' position. Now, in x86 land GRUB just passes the stub a bootparam structure, and I assume it just keeps filling the same structure in before passing it on to the kernel . On ARM*, we would need to get this information over "some other way", where the obvious candidate would be FDT. GRUB could register an empty devicetree, with only the initrd information in it, as a UEFI configuration table. (Getting a UUID for this was discussed in New Orleans.) Or, on systems using FDT for hardware description, once firmware becomes mature enough to do this themselves - add this information to the system-provided one. The stub would then need to look for this devicetree, and if present, copy the initrd nodes across into the one it loads itself. Alternatively, we could define a special protocol for passing additional parameters to the stubbed kernel ... or a special protocol to pass a special FDT but I'm not sure we want yet another interface. Thoughts? / Leif

Re: [linaro-uefi-internal] [PATCH] ARMVE:SMBIOS: Enable smbios support on all ARMVE platform

by Steven Kinney

Hi Yi, One comment regarding the patch and non-existing files (*dsc) and the like, targeted by this patch, relative to the current tianocore-edk2 and resulting uefi-next codebase. I don't think patches targeting future file(s) benefit us prior to their inclusion within either tianocore-edk2 or direct addition into uefi-next via topic branch patch. There are a number of ways this could create undue stress, in the future, when the patch has a sane codebase. IMHO, we should only create patches for current source in either existing uefi-next or tianocore-edk2 source code, not future source code that may change significantly between patch generation and its eventual application. I am using you previous patch, which does not include the future source code, not present in the current tianocore-edk2. I see no value in creating patches based on a possible source code revision; to many permutations possible prior to the patches application.

linaro uefi-next 13.09-rc1

by Ryan Harkin

Hi all, The uefi-next.git tree [1] has been updated for the 13.09 cycle. We're at -rc1, but the code freeze is today, so probably not enough time for any changes before the release. Snapshot binaries are available now [2] What's included? Well, not as much as I hoped because I've run out of time. So no ethernet and no SMBIOS patches just yet. Current topic branches: linaro-topic-a5 linaro-topic-a9 linaro-topic-arndale linaro-topic-bds linaro-topic-fvp linaro-topic-misc linaro-topic-origen linaro-topic-panda linaro-topic-tc1 linaro-topic-tc2 As always, you should probably pull and build the "linaro-tracking" branch, not one of the topic branches. The main addition for this release is the (now) upstream aarch64 support. The uefi_rtsm-ve-aemv8.bin snapshot binary will boot on the Aarch64 VE model that is currently available to Linaro internal people from the usual place [4] I've tested A9, TC2, FVP on the snapshot binaries. I tested RTSMs, aarch64 VE model and Arndale on my own build of the code and Dave Long has tested Panda on his own build of the same code. One problem I note for aarch64 is that we don't have a similar fix to this for native building: 4511a19 2012-12-12 BaseTools: allow native building [Leif Lindholm] Probably not a big issue, who would want to compile aarch64 inside a model?? Regards, Ryan.

Having problem with booting panda!!!

by davidson mistral

Hi, I have checked out to the 2012.09.1 branch of the u-boot-linaro-stable source and built the u-boot for panda. It worked fine. Then I enabled the Debug prints and again built the u-boot. But this time the u-boot hanged up in the middle. In my observations, it hanged up at the end of the board_init_f() function in the arch/arm/lib/board.c. At the end it has the relocate_code() function that might cause the problem. Im stuck up with this and any help would be appreciated. Thanks, Davidson. K

[PROPOSAL] ARM/FDT: passing multiple binaries to a kernel

by Andre Przywara

Hi, a normal Linux kernel currently supports reading the start and end address of a single binary blob via the FDT's /chosen node. This will be interpreted as the location of an initial RAM disk. The Xen hypervisor itself is a kernel, but needs up to _two_ binaries for proper operation: a Dom0 Linux kernel and it's associated initrd. On x86 this is solved via the multiboot protocol used by the Grub bootloader, which supports to pass an arbitrary number of binary modules to any kernel. Since in the ARM world we have the versatile device tree, we don't need to implement the mulitboot protocol. So I'd like to propose a new binding which denotes binary modules a kernel can use at it's own discretion. The need is triggered by the Xen hypervisor (which already uses a very similar scheme), but the approach is deliberately chosen to be as generic as possible to allow future uses (like passing firmware blobs for devices or the like). Credits for this go to Ian Campbell, who started something very similar [1] for the Xen hypervisor. The intention of this proposal is to make this generic and publicly documented. Looking forward to any comments! Thanks, Andre. [1] http://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=docs/misc/arm/device-tree… ---------------------------- * Multiple boot modules device tree bindings Boot loaders wanting to pass multiple additional binaries to a kernel shall add a node "module" for each binary blob under the /chosen node with the following properties: - compatible: compatible = "boot,module"; A bootloader may add names to more specifically describe the module, e.g. Xen may use "xen,dom0-kernel" or "xen,dom0-ramdisk". If possible a kernel should be able to use modules even without a descriptive naming, by enumerating them in order and using hard-coded meanings for each module (e.g. first is kernel, second is initrd). - reg: specifies the base physical address and size of a region in memory where the bootloader loaded the respective binary data to. - bootargs: An optional property describing arguments to use for this module. Could be a command line or configuration data. Example: /chosen { #size-cells = <0x1>; #address-cells = <0x1>; module@0 { compatible = "xen,linux-zimage", "xen,multiboot-module", "boot,module"; reg = <0x80000000 0x003dcff8>; bootargs = "console=hvc0 earlyprintk ro root=/dev/sda1 nosmp"; }; module@1 { compatible = "xen,linux-initrd", "xen,multiboot-module", "boot,module"; reg = <0x08000000 0x00123456>; }; ...

Right, this is just a text file with a list of binaries. It is not really the multiboot spec. There is no reason for this part to be different for grub on ARM. There is a big advantage to reusing the distro side tooling. If there isn't really much reuse on the bootloader side, then I'm fine with a different bootloader to Xen interface. I would like to hear that from folks working on grub though. > For u-boot Andre has proposed some syntactic sugar over the "fdt" > command to make boot.scr more trivial to use.

There is not much love for boot.scr either. There is work to address what are not really machine differences, but largely vendor u-boot differences: http://www.mail-archive.com/u-boot@lists.denx.de/msg119025.html One option for u-boot which already supports syslinux style menu files is to adopt the syslinux multiboot parsing support: http://www.syslinux.org/wiki/index.php/Doc/mboot We need to back-up and consider what this looks like in the end for all the pieces and get input from folks on grub, UEFI, and armv8. The UEFI answer may be this is a grub problem. For armv8, this proposal does match up well as the kernel boot interface for v8 is DT. Despite some claims, ACPI will not completely replace DT because of this. Rob

Last I checked the patches have been posted for merging, but it is stalled on the Grub maintainer. I believe he wanted to fix a bug on the raspberry pi before merging. Leif would know more.

(Note: this isn't implemented yet, but is in progress) The DTB will need to be passed via the UEFI system table. Initrd is passed by modifying the dtb with linux,initrd-* properties in the device tree. In the Xen case, I think the original proposal is conceptually sound. I'll quibble about a couple of the details, but I'll address those with a reply to the original proposal. It makes perfect sense to use the same mechanism as the initrd properties to tell the kernel about additional blobs. > Or are you saying the stub should load the initramfs itself?

Having Linux's stub parse the grub CFG is > even less likely to work well IMHO. The stub has the ability to load both the dtb and initrd itself by adding "dtb=" and "initrd=" arguments, but it is currently limited to loading images from the same filesystem that the kernel was loaded from.

Panda UEFI link error

by David Long

I discovered a link problem with uefi-next when building for panda. Apparently a couple new functions need to be added to the platform-specific helper code for panda. As suggested by Leif I will reply with the patch. -dl

Re: UEFI configuration on ARM VE TC2

by Leif Lindholm

Hi Vijay, The Linaro boot-architecture mailing list is a better forum for questions about the Linaro UEFI releases. I have cc:d this email to that list. The reason you do not see TFTP boot as an option is that that is not yet released. We are hoping to do this shortly. It would probably be a good idea for us to mention that in the documentation. I do not recognise the other error message. / Leif On Mon, Sep 02, 2013 at 05:01:23PM +0530, Vijay Kilari wrote: > Hi Leif Lindholm, > > > I am changing to UEFI from u-boot on my TC2 board. > I have followed the step listed under "Firmware Update" tab from below link > http://releases.linaro.org/13.06/ubuntu/vexpress/ > > After reboot, I see that uefi fails to load kernel image with below log > > > The default boot selection will start in 1 seconds > ERROR: Did not find Linux kernel. > [1] Linaro image on SD card > - VenHw(09831032-6FA3-4484-AF4F-0A000A8D3A82)/HD(1,MBR,0x00000000,0x3F,0x19FC0)/uImage > - Initrd: > VenHw(09831032-6FA3-4484-AF4F-0A000A8D3A82)/HD(1,MBR,0x00000000,0x3F,0x19FC0)/uInitrd > - Arguments: console=ttyAMA0,38400n8 root=/dev/mmcblk0p2 > rootwait ro androidboot.console=ttyAMA0 mmci.fmax=12000000 > - FDT: VenHw(09831032-6FA3-4484-AF4F-0A000A8D3A82)/HD(1,MBR,0x00000000,0x3F,0x19FC0)/v2p-ca15-tc2.dtb > - LoaderType: Linux kernel with Local FDT > ----------------------- > Global FDT Config > - VenHw(09831032-6FA3-4484-AF4F-0A000A8D3A82)/HD(1,MBR,0x00000000,0x3F,0x19FC0)/v2p-ca15-tc2.dtb > ----------------------- > [a] Boot Manager > [b] Shell > [c] Reboot > [d] Shutdown > Start: a > [1] Add Boot Device Entry > [2] Update Boot Device Entry > [3] Remove Boot Device Entry > [4] Update FDT path > [5] Return to main menu > Choice: 3 > [1] Linaro image on SD card > Delete entry: 1 > [1] Add Boot Device Entry > [2] Update Boot Device Entry > [3] Remove Boot Device Entry > [4] Update FDT path > [5] Return to main menu > Choice: 1 > [1] VenHw(E7223039-5836-41E1-B542-D7EC736C5E59) > [2] VenHw(02118005-9DA7-443A-92D5-781F022AEDBB) > [3] VenHw(1F15DA3C-37FF-4070-B471-BB4AF12A724A) > [4] VenHw(CC2CBF29-1498-4CDD-8171-F8B6B41D0909) > [5] VenHw(09831032-6FA3-4484-AF4F-0A000A8D3A82) > Select the Boot Device: > > > When I try to delete and add new boot entry, I dont see option for TFTP option > unlike it is mentioned in > > https://wiki.linaro.org/ARM/UEFI#Configuring_A5.2C_TC1_and_TC2 > > Can you please help me in configuring it?. > > In fact, when I try to add an entry, uefi asks for kernel start > address like below > > [1] Add Boot Device Entry > [2] Update Boot Device Entry > [3] Remove Boot Device Entry > [4] Update FDT path > [5] Return to main menu > Choice: 1 > [1] VenHw(E7223039-5836-41E1-B542-D7EC736C5E59) > [2] VenHw(02118005-9DA7-443A-92D5-781F022AEDBB) > [3] VenHw(1F15DA3C-37FF-4070-B471-BB4AF12A724A) > [4] VenHw(CC2CBF29-1498-4CDD-8171-F8B6B41D0909) > [5] VenHw(09831032-6FA3-4484-AF4F-0A000A8D3A82) > Select the Boot Device: 5 > Starting Address of the EFI Application or the kernel: > > What should be the address that I should give here?.

RE: ARM 64-bit - UEFI on the AArch64 Models

by Olivier Martin

All the patches required to build UEFI for the ARM Foundation and Base Models have been committed to subversion (revision 14628). The wikipage (https://sourceforge.net/apps/mediawiki/tianocore/index.php?title=ArmPlatfor mPkg/AArch64) has been updated to use the repository instead of the snapshot. It is recommended to apply the patch "Fixed calculation of BaseOfCode in GenFw when the first code section is aligned" (sent on July 16th on the mailing-list). A copy of this patch can be found in ArmPlatformPkg/Documentation/patch/BaseTools-Pending-Patches.patch. patch -p1 < ArmPlatformPkg/Documentation/patches/BaseTools-Pending-Patches.patch The snapshot contains changes to add AArch64 support to EdkShellPkg (required to start UEFI SCT) that is not yet into subversion. The latest version of this patch will be sent soon on the mailing-list. From: Olivier Martin [mailto:olivier.martin@arm.com] Sent: 26 July 2013 21:34 To: edk2-devel(a)lists.sourceforge.net; boot-architecture(a)lists.linaro.org Cc: Harry Liebel Subject: ARM 64-bit - UEFI on the AArch64 Models After the UEFI 2.4 specification - that contains the AArch64 (the ARM 64-bit architecture) Binding - was approved last week, I started to send the AArch64 patchset to be reviewed by the different EDK2 maintainers. Because patches are still waiting to be approved and also not all the patches have been sent yet (such as the pre-built binaries and few minor others), I created a snapshot of the latest subversion (svn rev 14505 - Friday 26 Jul 2013) with the AArch64 pathset to make it easier for people to play with UEFI on AArch64 platforms. The main reason of creating a snapshot and not a patch is binary data are not really portable in patch files. This archive is only a short term solution and should not be considered as a release package (some AArch64 patches could diverge from their original revision). The archive will be removed after all the patches will have been accepted by the maintainers.

constraints on UEFI image link address

by Leif Lindholm

When testing Roy Franz's ARM UEFI stub kernel loader patches on a TC2 platform, the loader (correctly) highlighted an issue that has been lurking unnoticed for a while: the very UEFI image actually makes following the Linux boot protocol impossible. Roy's stub takes the paranoid (and correct) approach of explicitly allocating in UEFI the regions the zImage may need to be relocated to (based on original load address) and that which it will decompress into (based on some masking operations relative to the resulting entry point). It also attempts to allocate a "big enough" region to ensure the decompressed kernel, with BSS, will fit. This operation fails on the TC2 tianocore port, and if basic arithmetic does not fail me, would also fail at least on Samsung Arndale and TI Beagleboard (I have yet to verify). The problem is that on all these platforms, the UEFI binary is linked to execute at or near the start of RAM on the platform. Oliver figured this out for me for TC2, and has promised to look into what would be the best way of resolving this for that platform. On these platforms, kernel decompression may result in overwriting the initial UEFI image in RAM, before ExitBootServices(). While this may work on some platforms, there are no guarantees. This region could even contain code or data required by runtime services. I have updated the (fairly random) list of UEFI port requirements at https://wiki.linaro.org/LEG/Engineering/Kernel/UEFI/BSP But several BSPs will need to change, along with their documentation. / Leif

ARM 64-bit - UEFI on the AArch64 Models
