AMD LX northbridge question
by Christian Gmeiner June 3, 2013

June 3, 2013

Looking at src / northbridge / amd / lx / northbridge.c I see a the following lines: 400 static void pci_domain_enable(device_t dev) 401 { 402 printk(BIOS_SPEW, ">> Entering northbridge.c: %s\n", __func__); 403 404 // do this here for now -- this chip really breaks our device model 405 northbridge_init_early(); 406 cpubug(); 407 chipsetinit(); http://review.coreboot.org/gitweb?p=coreboot.git;a=blob;f=src/northbridge/a… Can somebody tell me why "this chip really breaks our device model"? And what would be the correct way to do it? thanks -- Christian Gmeiner, MSc

Best Supported Laptop
by slhac tivist June 3, 2013

Hi, Which supported laptop is the most free? According to the laptop section of: http://www.coreboot.org/Supported_Motherboards#Laptops The the status of the Roda and Getac board (both "OK") doesn't link to anything. Is the implication that coreboot works flawlessly on these boards? And how bad is the proprietary code? Can Getac and Roda still spy on me with it? I'd like to get a chromebook. The status is "OK" but links to a page that says there are proprietary components. What is microcode? What is MRC.bin and ME.bin? Again, can google control my laptop with this code? Finally, if the above options don't pan out, I could get a Lenovo. The X60[s] and T60[p] made no mention of proprietary code. :) Can anyone confirm this? That would be pretty sweet! The Lenovo X201 supports a faster cpu, but the status links to a page that says it has proprietary components too...anyone know anything about these proprietary components? I don't want Lenovo sending my laptop secret messages! Any advice would be greatly appreciated. My goal is to build a laptop that is 100% free of proprietary code... Thanks in advance!

Hijacking (was Trying to get coreboot running on VIA EPIA-M (lzma: Decoding error = 1) )

Let's call it a "fork" of the original thread. I couldn't help but notice you have a VIA southbridge. I'm currently working on de-duplicating SMBus code, and also have a VIA chipset handy. I see the SMBus of the 8235 is hellishly similar to the VX900 I'm working on. I have a patch which adds a generic SMBus implementation for VIA chipstes here: http://review.coreboot.org/#/c/144/ If you have the time and patience, could I ask you to pull that patch and mess with the 8235 early_smbus.c and Makefile.inc to take advantage of that code?

coreboot at LinuxTag and coreboot hackaton, Berlin, May 22-27 2013

Hi all, coreboot will again have a booth at LinuxTag in Berlin, May 22-25, in Hall 7.1c at Messe Berlin AKA "Messegelände unter dem Funkturm". (Translation: Fairground under the radio tower.) After LinuxTag we'll continue with a developer meeting/hackaton, May 26-27, in the rooms of the community ISP IN-Berlin at Lehrter Straße 53, not far from Berlin Hauptbahnhof, the central train station. If you can join us for LinuxTag and/or for the developer meeting please let us know your availability using the Doodle at http://goo.gl/0OO6z If you're interested in helping out at the LinuxTag booth please email me off-list. We have a little bit more space this year, but also many nice things to show off, and the Google guys will be doing a workshop on Friday, May 24, about building a custom coreboot ROM from scratch, and flashing it onto a Chromebook. The developer meeting is free of charge thanks to the generosity of our hosts at IN-Berlin, but please note that space is somewhat limited. If there is overwhelming interest then priority will be given according to general level of contributions in the community -- but don't be shy!! If you would like to join then simply sign up at the Doodle. For visitors who wish to book accomodation near the IN-Berlin location here are a few suggestions in order of proximity: * A&O Hostel and Hotel, Lehrter Str. 12, 700m down the street http://www.aohostels.com/en/berlin/berlin-hauptbahnhof/ * Berliner Stadtmission Christian Jugendgästehaus, Lehrter Str. 66, 950m http://www.jgh-hauptbahnhof.de/ * Motel One, corner of Invalidenstr. and Lehrter Str., 1.2km http://www.motel-one.com/de/hotels/berlin/hotel-berlin-hauptbahnhof/ The central train station is in the opposite direction, ie. Motel One is closest to the station. S-Bahn line S5 toward Spandau departs from Hauptbahnhof track 16, the 7:th stop is Messe Süd where LinuxTag is. NOTE: Several other S-lines depart from track 16, but only S5 Spandau takes you to Messe Süd! Remember to validate (insert into little red machine which timestamps) your ticket if you travel by S-Bahn. The fine is 40 EUR and checks especially on the east-west line are frequent-ish. The developer meeting starts on Sunday morning and formally ends on Monday afternoon but there may also be some informal meetings or perhaps sightseeing excursions on Tuesday. There are grocery stores nearby IN-Berlin, we can use the kitchen if we want to, and they have an assortment of alcoholic and non-alcoholic beverages as well as sweets for sale at low cost. There is however not much in the way of restaurants nearby so I expect that we will order lunch to be delivered to IN-Berlin but leave in the evening and hit the city for dinner, and possibly tasty beverages. Looking forward to meeting you in Berlin //Peter

your mtrrs are probably still not right. Boot linux and cat /proc/mtrr (or whatever it is called) and see what it says. ron

I can now boot a kernel without MTRR support. But it takes much more time than with the normal Bios and syslinux. The coreboot and filo part without serial output and without vga bios is very fast. But it takes much time at 'Jumping to entry point.'. After that the kernel takes a bit more time starting.
