Re: [coreboot] Buy desktop mainboard

New versions may or may not work, sometimes they change critical components. *rolls dice* you could always see if they're on ebay. If I was you I'd buy a *new* KGPE-D16 (around $400), a cheap g34 62xx CPU off of ebay ($10-40) and a decent foss video card - it is blob free, one of the most popular coreboot boards and it has proper virtualization support including IOMMU/RVI (SLAT). You don't want a G41, even with a 771>775 xeon mod it is pretty old and lacks many features. 2008+ intel and AM4+ boards are just shimboot - If something contains blobs you have no real control, all of the real stuff is done by the black box "FSP" https://blogs.coreboot.org/blog/2015/02/23/the-truth-about-purism-why-libre… (new intel = will never be libre) https://www.coreboot.org/Binary_situation https://libreboot.org (good info here if you ignore the politics) On 11/06/2016 07:47 AM, José Manuel Bueno Cuesta wrote: > Hi, I want to buy a new desktop mainboard compatible with coreboot, > but I have not found any of the ones listed in the supported boards > webpage (because they are too old).

Coreboot is hanging while going to S3
by Alok Kumar 10 Nov '16

10 Nov '16

Hi All, I want to increase my debug capabilities while working on coreboot with S3 issues. I am facing proble, and system is hanging while going to S3. I am trying to figureout the root cause for this issue. While going to S3 their is no Debug messages so its becoming diffcullt for me to root cause this issue. I am aware of _PTS and _WAK method of ACPI tables. So here are my question for the intel platform: a) What are the drivers will come into picture while going to S3. b) How to enable the DEBUF messages while going S3. So that how the Boot Scripts tables are getting saved. c) What is the list of drivers in coreboot which may take the control while goijng to S3. d) In which driver we generaly enable PME_B0_EN bit in the case if we are not setting this BIT into _PTS method. Please note that I am working on Intel platforms. Regards Alok Kumar Agarwal

Gerrit cleanup: Abandoning patches older than 18 months
by Martin Roth 10 Nov '16

10 Nov '16

I've just completed another round of gerrit cleanup, abandoning a bunch of patches that are older than 18 months. Here's a link to what was just abandoned: https://review.coreboot.org/#/q/status:abandoned+comment:%22Cleanup:+Abando… I plan to do this again in another month, abandoning any patches found by this query: https://review.coreboot.org/#/q/is:open+before:2015-06-15 Some of these patches might still be valuable, so please feel free to pick up any abandoned patches that you want to work on to try to integrate.

If there is really something missing, it would be very board (or maybe ThinkPad) specific, I suppose. So nothing standard, hard to find an example. Sometimes there's something that can be configured at the OS level if the firmware haven't done so yet. Sometimes you need to disable a single device/chip when the system goes into a sleep state. Looking at the "tunables" in the powertop tool might be a good idea. > > I see some boards have cstates support, like > src/mainboard/lenovo/x200/cstates.c and after googling I found that > libreboot had "Higher battery life on GM45 (X200, T400, T500, R400) > due to higher cstates now being supported (thanks Arthur Heymans).

This is defined in the ACPI specification [1, p.381..]. The last 0x30 in that patch gives the number of the C-state, IIRC. coreboot actually uses C4, too, it's just using a weird register to tell the hardware to use C4 when C3 is requested (see 2a1847e lenovo/x200,t400: enable C4 cpu low power state). The 0x30 is an operand to the MWAIT instruction [2]. But again, this all should work fine for Ivy Bridge. > > I have found http://www.intel.com/content/www/us/en/support/processors/000006619.html > but that is not super helpful. Well, most of Intel's public documentation is about how you make use of their technology from an OS perspective.

Usually ACPI methods are called on standardized events from the kernel. So you might have to write a kernel driver to call your method (just noticed there exists `acpi_call` in the bumblebee project). Writing a register isn't very straight forward (nothing seems to be in ACPI). Generally you have to define a `OperationRegion` that represents a part of memory or i/o space, and define a `Field` of registers over that. `southbridge/intel/bd82x6x/acpi/smbus.asl` might be a good example. The second `OperationRegion` there works on i/o ports, I guess you need something similar to change GPIO settings.

grub as payload: Where to put the grub.cfg?
by Philipp Stanner 09 Nov '16

09 Nov '16

Hi, I'm currently busy making cb+grub running. While I can boot successfully (qemu) using the grub-shell I of course want to automatize this process. But how and where do I have to put the grub.cfg file? The wiki doesn't include much informations about this. I would appreciate if someone could help me :)

Re: [coreboot] radare
by Rafael Machado 09 Nov '16

09 Nov '16

Hi guys I usually do the following to play with the coreboot images: radare2 -b 16 Desktop\coreboot.rom [f000:fff0]> pd 3 ;-- entry0: `=< f000:fff0 e98df7 jmp 0xff780 f000:fff3 ff invalid f000:fff4 ff6690 jmp word [bp - 0x70] [f000:fff0]> After I saw the "-b 16" on a post at the internet the magic started to work. But in case this bios you are checking is a UEFI bios (maybe it is since it's a AMI bios), things will change a little bit. I'm not sure about how to work with uefi images at radare yet. Maybe you can use the UEFITool to try to help you: https://github.com/LongSoft/UEFITool/releases/tag/A32 Thanks and good luck.
