After the first run of a cpu/northbridge /southbridge_smi_handler() function, the cause of the SMI should be handled and thus the second run should do nothing (but checking for the SMI's cause). Does that help? I wasn't sure if I got your question right. Nico

logical error for smm hander in coreboot.
by Tang Tank 02 Jan '17

02 Jan '17

Hi all, For smm handler (func smm_handler_start) in coreboot/src/cpu/x86/smm/smm_module_handler.c, there may be a logical error. If I have 4 cores in my mainboard in the following special conditions: 1. core0 run into smm_handler_start and smi_handler_status will be SMI_LOCKED. 2. core1/2 run into smm_handler_start and pause since smi_handler_status is locked. 3. core0 release smi_handler_status and then core4 run into smm_handler_start, it will do southbridge_smi_handler again. So is there have a reliable way of doing smm multi processors services in coreboot? Thanks Tank

[GRUB2][PAYLOAD] How to integrate grub.cfg
by megagolgoth 02 Jan '17

02 Jan '17

Hi, I successfully compile and flash Coreboot for a x220, with SeaBios as payload. I follow steps on these page : "https://www.coreboot.org/Board:lenovo/x220" "https://www.coreboot.org/Build_HOWTO" "https://www.coreboot.org/VGA_support" (Done it 2 month ago with "bios_extract" , now it fails, I don't know why... But I got the extracted BLOB) My goal is having Qubes installed with HDD completely encrypted, ME (1,5MB version) disable ("https://github.com/corna/me_cleaner"), and Seabios available in case of need. I have three step to do for that : 1. Using Grub2 as Coreboot payload, with Seabios as Grub2 payload. 2. Find a 1,5MB version of ME (from a Chromebook). Applying me_cleaner.py on coreboot.romn at the end. 3. Installing Qubes fully encrypted ("https://github.com/QubesOS/qubes-issues/issues/2118"). My questions are : 1. I'm stuck because I didn't know how to integrate or make Grub2 use my grub.cfg. How to do? 2. Where can I find a Chromebook BIOS (or a 1,5MB ME) ? 3. Is someone did that? Any recommendation? Jérémie.

Re: [coreboot] nvramtool options
by ron minnich 01 Jan '17

01 Jan '17

well, I would suggest looking at the nvramtool code and seeing what it is that makes it print that message, i.e., what is it looking for that it is not finding? The look at coreboot.rom file and see if the string it is looking for is in the rom image. Let's start there. There is no substitute for spending a bit of time understanding WHY an error message is printed, not just WHAT is printed. Can you ask you IT folks to remove that silly string: "DISCLAIMER: This message is proprietary to Aricent and is intended solely for the use of the individual to whom it is addressed. It may contain privileged or confidential information and should not be circulated or used for any purpose other than for what it is intended.

Offering Gigabyte GA-890FXA-UD5 for porting
by Merlin Büge 01 Jan '17

01 Jan '17

Hey all, I have a nice Gigabyte mainboard which I don't need/use anymore: A Gigabyte GA-890FXA-UD5 (rev. 2.0 or 2.1) http://www.gigabyte.de/products/product-page.aspx?pid=3519 Since I like libre-friendly computing hardware, I'd find it nice to see libreboot running on it. I'm not sure, but from what I see, it should be libreboot compatible? Could someone more knowledged than me confirm this? If someone is interested in porting this board to coreboot, and if there are no big foreseeable obstacles to porting it to lireboot, I'd be happy donating that board together with a Phenom II 965 and 4G RAM, preferrable to someone in Germany or within the EU (shipping costs). Regards, Merlin -- Merlin Büge <toni(a)bluenox07.de>
