linaro armv8 kernel crashdump (kdump?)
Hi All, I'd like to investigate kernel crashdump debuging for armv8. For this I need a crashdump, basically I would be happy with a vmlinux with debuginfos (-g compiled) either as 1 a.out or a splitted a.out ( ala suse) a save state of some sort (a crash notes records) and a vmcore that could be a simple raw file, a core file, an elf file, a kdump format. I am not to picky on the crashdump format for the time being. What would be my best bet? - Does someone as a crashdump at hand, I would simply download the vmlinux/vmcore/crashnotes. - Make it myself as a qemu guest crash. If qemu is able to produce a guest core dump, I could build a kernel -g then trig a guest dump (if someone did this any receipe would be appreciated :) ) - Make it myself with a manual kdump (ideal) or kexec phases. I would then have to install linaro, get the source, build the -g vmlinux, then try some kexec sequence and catch the kcore, or better if available I could do a makedumpfile to get a kdump. Again if one did this, any help appreciated. Cheers, Phi ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev

[PATCH 1/2] USB: OHCI: make ohci-platform a separate driver
This patch splits the ohci-platform code from ohci-hcd out
into its own separate driver module.This work is part of enabling
multi-platform kernels on ARM.
In V2:
-Passed "hcd" argument instead of "ohci" in ohci_setup() because it is
using "struct usb_hcd" argument.
In V3:
-Directly passed "hcd" argument not required to call ohci_to_hcd() function.

Until now none of the platform drivers has used this private space,

Re: [ANNOUNCE] linux-linaro kernel schedule / llct age
On 22/05/13 02:48, the mail apparently from Andrey Konovalov included: The next steps are: May 22: ll rebuild based on llct-20130521.0 May 23: ll rebuild based on llct-20130521.0, linux-linaro release candidate, code freeze The last llct update for this cycle is scheduled on May 21, The last linux-linaro update for this cycle is scheduled on May 23. May 23 is the linux-linaro code freeze for 13.05 (only bug fixes allowed after this date). This happened, which is good, but llct has not updated for 3.10-rc3 or 3.10-rc4 yet, which is not good; llct is two weeks old. Something similar happened last month. I realize this isn't the case for everyone but actually the literal "schedule for 13.05" holds zero interest for me. Timely updates on llct for each mainline -rc are very interesting though, in fact we depend on them. Is it possible things have gotten a little unbalanced with all the excitement of "code freezes", "releases", "schedules" that make the choo-choo noises for the monthly release train set, we're not giving the llct tracking activity enough love? -Andy -- Andy Green | Fujitsu Landing Team Leader Linaro.org │ Open source software for ARM SoCs | Follow Linaro http://facebook.com/pages/Linaro/155974581091106 - http://twitter.com/#!/linaroorg - http://linaro.org/linaro-blog ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
