However, we will add the new names to the in-program (and hence wiki) database so that this new information becomes public. Thanks for the heads up, Victor. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Re: [flashrom] [coreboot] [LinuxBoot] FOSDEM 2019 deadline today

by Carl-Daniel Hailfinger

In that case, I'd also like to point you to the deadline for submitting main track talks which is tomorrow(!). https://fosdem.org/2019/news/2018-08-10-call-for-participation/ Having a coreboot/LinuxBoot talk there would be awesome. Ron/David, could you submit something or do you have someone in mind who can do that? There's also lightning talks, deadline is a bit later. OK, I'm submitting a request for a stand. I need a backup contact for the stand. Who is willing to do that? AFAICS we can still change the backup contact later if life happens.

80/100/132 column line width policy

by Carl-Daniel Hailfinger

Hi, we're hitting the 80 column limit in our code in ways which actually reduce readability for the code. Examples are various multiline messages and complicated nested code where refactoring to a separate function doesn't make sense. Keeping the old 80 column limit is not really an option anymore. Standard terminal sizes have one of 80, 100 or 132 columns. Given the monitor resolutions many people have nowadays, I think it is safe to say that you can fit two xterms with 100 columns horizonally next to each other. 100 columns should also be sufficient for a msg_p* of roughly 80 columns of text. 132 columns provide more leeway, but IMHO that would be too wide for good readability (and my screen can't fit two xterms side-by-side anymore). Of course some files have sections where any column limit is not acceptable (board lists etc.), but the column limit violations should be limited to the affected file sections, not whole files. Comments? I'd like to get this decided today or tomorrow so we know where we need line breaks in Stefan Tauner's new struct flashchip patch. Regards, Carl-Daniel -- http://www.hailfinger.org/

FOSDEM Hardware Enablement Devroom

by Paul Kocialkowski

A Hardware Enablement devroom will be taking place at FOSDEM this year, on Sunday 10 December 2017. This newly-created devroom is the result of 3 proposals that were merged together. It is co-organized by several individuals. The devroom covers all aspects related to hardware enablement and support with free software, including aspects related to boot software, firmwares, drivers and userspace tools and adaptation. Proposals for talks related to these topics are welcome and can be submitted until Sunday 26 November 2017 via the pentabarf interface. Short talks are encouraged over longer ones in order to cover a wide range of topics. The announcement for the devroom, that contains all the useful information, was published at: https://lists.fosdem.org/pipermail/fosdem/2017-October/002649.html Cheers and see you at FOSDEM! -- Paul Kocialkowski, developer of free digital technology and hardware support Website: https://www.paulk.fr/ Coding blog: https://code.paulk.fr/ Git repositories: https://git.paulk.fr/ https://git.code.paulk.fr/

Question about SIL3114 board with a N28F010-120 flash chip on it

by Peter Cost

Dear Reader, I have a SIL3114 PCI board with an Intel N28F010-120 flash chip on it, and I can't reprogram it since it lacks the 12V Vpp. I checked that there is no +12V connection on the PCI edge connector of the board and the VPP pin seems to be unconnected. My question is this. When I apply 12V Vpp to the chip will I then be able to reprogram the board with the Lattice (Silicon Image) dos utility or the flashrom utility. I am an experienced engineer, but my eprom day's are from way back in the 80's and early 90's and I have never done anything with flash proms other than reprogramming boards with the supplied software. Thanks for any response. Kind regards, Peter Cost

Heads Up: Ongoing layout-support work

by Nico Huber

Dear fellow flashrom contributors, I'll likely work on flashrom's layout support in the next few weeks. Part of it will be to finalize the work on per-region file arguments. There were multiple proposals for the command-line syntax without a real consent so far, [1] sums it up. If you have any preferences, please comment soon before things are set in stone.

Researching Lenovo IdeaPad 300-15ISK for Possible Future Support with FlashROM, and Later, CoreBoot

by moriel5

The title pretty much sums it up, however here are the details. I have managed to get a hold of my laptop's schematics due to them being leaked.I am currently working with someone over at Bios-Mods to modify the firmware ("unlocking it").Interestingly, this laptop (which I had already updated it's firmware), has no WiFi whitelist, and I had bought brand-new, about a month after it came out. The EC controller, an ITE IT8586E-LQFP, is connected via the LCP bus, and the touchpad, internal keyboard, and the NCT7718W thermal sensor are all connected to it, according to the schematics.I forget whether I have the same exact chip (though I believe it to be so) on my laptop, as 99% of the details match my laptop. The schematics refer to 2 SPI chips, an 8MB W25Q64FVSSIQ_SO8 on UC3 as the main SPI chip, and an 4MB W25Q32FVSSIQ_SO8 on UC6 as backup.I have only one SPI chip, an 8MB W25Q64FVS1011532 on UC3, with the UC6 solder point existing, so I could theoretically solder a backup SPI chip.A TPM chip, the Z32H320TC, also sits on the LCP bus, with a direct connection to the chipset, unlike the touchpad, internal keyboard and the thermal sensor, according to the schematics.I forget whether I have this TPM chip, but once again, I believe that it is so. The IdeaPad 300-15's motherboard is codenamed "Paris". It also (optionally) comes with an AMD dGPU, without direct connection to any graphical output.My specific model only has no dGPU. Can anyone help me with my research? I'm still not very experienced with the actual work regarding electronics, most of my experience is with researching them.If there is any more information required from the schematics, I'll gladly share them, and if anyone wants the schematics, I can send them over.
