If you have extra white cups I'll buy those too. If I don't make it in person I'll ask if someone might courier cash and goodies on my behalf. Let me know the amount. Thanks a lot!

Goodies for Bonn meeting
by Vladimir 'φ-coder/phcoder' Serbinenko 06 Oct '15

06 Oct '15

Hello, all. My girlfriend Maria (CC'ed) would like to organize some goodies for coreboot meeting. Already available are black T-shirts: 2 x M, 8 x L, 1 x XL according to my notes, it's no guarantee, I can't double-check now as I'm travelling. Expected price is under €20 for any of items. Capacity is limited, first come first serve, respond to this e-mail to order. What else we can do: - White t-shirt - white cups - colour cups - Fridge magnets - case for iPhone (indicate which one), not sure which ones are available - Beer coaster - mouse pad - baseball cap In addition, if you're ok with waiting about a month + delivery time we can order: - Black t-shirt (other than the sizes mentioned above, or once the stock is out) - Colour t-shirt over €20 We're doing it just for fun and to serve the community, the price is only to cover our costs.

Compiling HowTo?
by NOQ2 Webmaster 06 Oct '15

06 Oct '15

Hello, Are there any more detailed descriptions on how to create a coreboot image for let´s say Thinkpad x61 or x230? Most of the online guides out there just describe the coreboot flashing procedure itself, not how the image was compiled before (especially which settings are of importance, how to cope with two eeprom chips in x230 - does it suffice to compile / flash a 4M image?). Any help appreciated :-) noq2

Re: [coreboot] cbmem fails with `Failed to mmap /dev/mem: Resource temporarily unavailable`
by Aaron Durbin 05 Oct '15

05 Oct '15

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drive… That patch added dmi_init() which maintains a persistent dmi mapping. However, that code used ioremap() as it's mapping. Thus, we have an uncached-minus PAT entry covering the DMI tables. I'm actually not sure why they don't just maintain a copy of the tables -- maybe for eventlog purposes? So that PAT entry will always cause issues w/ cbmem trying to do brute force 1MiB mappings of /dev/mem.

About the USB issue on the Lenovo T420 port
by Iru Cai 05 Oct '15

05 Oct '15

Hi, I'm using the new Lenovo T420 port on gerrit[1] and found a bug about USB(in my post on the gerrit page). And just now I found a work around on this issue. First I tested a USB disk on the buggy USB port before suspending the system, it works fine. Then I unplugged the USB disk, suspended my system, resume, and replugged the disk, the bug occurred. Then I unplugged the disk, reload the ehci_pci module as follows: rmmod ehci_pci modprobe ehci-pci The I plugged in the USB disk, it worked fine again. I think the kernel message[2] gives some information about it, because it gives two different port number on the USB device. But I know almost nothing about USB, so I'm not sure what's happening.

Emergency: Talks needed for coreboot conference in Bonn
by Carl-Daniel Hailfinger 04 Oct '15

04 Oct '15

Hey everyone, due to various reasons, a few speakers can't make it to the conference and thus I have a severe lack of talks and the agenda is starting to look like swiss cheese (holes everywhere). Admittedly I do love swiss cheese (so many delicious kinds of cheese), but for a conference agenda I'd rather like to have less holes. PLEASE PLEASE if you attend the conference PLEASE consider doing a talk about something - anything really - even if it's just three slides and five minutes of talking, followed by lots of discussion from/with the audience. Any proposals (title, duration (talk/discussion), name of speaker, preferred time (morning, noon, afternoon)) are highly appreciated. PLEASE send them to <coreboot-conference(a)bsi.bund.de> ASAP so I can allocate a slot for you. If you can't come but would be willing to donate slides for someone else to do a talk on your behalf, PLEASE tell me at <coreboot-conference(a)bsi.bund.de> or hit me up on IRC. Doing talks remotely via a video conference system of your choice is also an option. THANK YOU! Regards, Carl-Daniel
