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

I'd also like to avoid having the stub merge FDT contents from different trees.

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
