Problem with implementing workaround from errata
by Łukasz Dobrowolski 23 Jul '17

23 Jul '17

Hi! I've resumed my work non ThinkPad X120e. I have a problem with random hangs during boot. The hang occurs in vendorcode/amd/cimx/sb800/SBPort.c:296. After a long fight I was able to diagnose the issue. It's described in errata (attached) on page 13. There is a suggested workaround, however the description is not verbose enough for me. Could somebody give me some hints? The functions are entered in this order: (?) cache_as_ram_setup: //cpu/amd/agesa/cache_as_ram.inc void * asmlinkage romstage_main(unsigned long bist) //cpu/amd/agesa/romstage.c void platform_once(struct sysinfo *cb) //cpu/amd/agesa/family14/romstage.c void sb_Poweron_Init(void) //southbridge/amd/cimx/sb800/early.c VOID sbPowerOnInit(IN AMDSBCFG* pConfig) //vendorcode/amd/cimx/sb800/SBPort.c (hang!) Where should I put the workaround if I can't pollute the shared code? The code for the port is based on asrock/e350m1. I can upload it to gerrit if needed but not much was changed. -- Łukasz Dobrowolski

Re: [coreboot] another AMT exploit

This is the same bug we lamented before. Siemens's IPCs are nothing more beneath the hood as normal PCs, using the same set of the CPU + PCH (serving to the purpose), just the silicon and platform packaging are special (to withstand temperatures from -40C to +85C). The packages provided are just set of the improved BIOSes and the improved MEs (BIOSes done/improved by Siemens, MEs transparently taken from INTEL). Once this bug is discovered, it affects ALL the devices and machines based upon released INTEL CORE families till May 2017. So, this is just an extension of the original bug, my best guess, Siemens Industrial must announce this bug as well, since they are responsible for their own devices and IPCs as eOEM, don't they???

What makes ME seem all the more sketchy is how evasive intel is about it, logic would dictate that the most money would be made via making it a removable TPM style module (buy or no blurays for you $$$$) but instead they choose to integrate it and make it mandatory. I wonder how hard would it be for a foreign intelligence agency to ruin a country via convincing an intel employee to embed a ME program on every new PC that introduces subtle errors to various important calculations...better than a physical hardware flaw as your own stuff isn't vulnerable.

I think I'm using a pl2303 at the moment, but I'm sure any other will work as well. What you need to connect is only EC_TX <-> RX, EC_RX <-> TX and GND <-> GND.

I've just soldered dupont cables to my device because I only use it as a dev unit. What I want to implement next in Origami-EC is charger and battery support, but I didn't have enough free time to dive into the implementation of it.

ASUS KGPE-D16 PIKE slot usable as a PCI-e x4 slot
by Christian E. Jørgensen 21 Jul '17

21 Jul '17

Has anyone here tried this: https://hardforum.com/threads/asus-pike-is-usable-as-pcie-x4.1781277/ ? Unfortunately, the pictures are gone, but I assume something like this http://www.ebay.com/itm/PCI-E-4X-to-4X-Riser-Card-Extender-Express-Extensio… and a low profile card are required. In any case, an extra PCI-e x4 slot may come in handy. :-) Christian

Cherry Trail Support
by Arne Zachlod 21 Jul '17

21 Jul '17

Hi all, I got a GPD Pocket with an Atom X7-Z8750 (Cherry Trail). I would like to use coreboot with it, but there seems to be no support for Cherry Trail, is support for this platform planned/worked on or is this more likely not going to happen? Thanks, Arne
