cmos.layout: power_on_after_fail
by Iru Cai 02 May '15

02 May '15

Hi, After I set CONFIG_USE_OPTION_TABLE, my laptop will power on when I plug in the AC adapter. Then I find disabling `power_on_after_fail' will prevent my laptop from booting when AC is plugged in. So I wonder why this setting is called `power_on_after_fail' instead of `power on AC attach' as with the vendor BIOS?

I think making it depend on EXPERT is a great idea. I'd also like the interface to be friendlier. What granularity is actually supported for the option? I doubt that it's single bytes? Maybe make it decimal kb? The default value depends on ROM_SIZE, right? //Peter

The big difference is that users never see the actual ROM_SIZE value. They see a friendly list of common flash chip sizes, with the default being what ships with the particular board. > The actually supported granularity is anything that CBFS/cbfstool > supports as an image size, which I think is in theory arbitrary down > to individual bytes.

Kconfig: Move `CBFS_SIZE` out of main section
by Paul Menzel 01 May '15

01 May '15

Dear coreboot folks, commit f780c40f (CBFS: Correct ROM_SIZE for ARM boards, use CBFS_SIZE for cbfstool) [1] adds a description to the Kconfig variable `CBFS_SIZE`, which makes it, I think, visible in the Kconfig menu (`make menuconfig`). […] │ ┌─────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┐ │ │ │ General setup ---> │ │ │ │ Mainboard ---> │ │ │ │ Chipset ---> │ │ │ │ Devices ---> │ │ │ │ Display ---> │ │ │ │ Generic Drivers ---> │ │ │ │ Console ---> │ │ │ │ (0x400000) Size of CBFS filesystem in ROM │ │ │ │ System tables ---> │ │ │ │ Payload ---> │ │ │ │ Debugging ---> […] What section should (0x400000) Size of CBFS filesystem in ROM be moved to? Furthermore, should it even be visible or be hidden as an expert option? Thanks, Paul [1] http://review.coreboot.org/9619

After reading both of your replies to the test stand message, I was very angry and disappointed about the bad assumptions you both made and the, in my opinion, impolite style by using words like *spamming* and *annoying*. For the future I wish that we first assume that the other side is meaning well. So I should assume, both of you meant well too. But I just wanted to get it out. In the end, in my opinion, the Raptor Engineering Automated Test Stand¹ is the best contribution to the coreboot infrastructure since the switching to a git based workflow. So big thanks to Raptor Engineering and Timothy! Thanks, Paul ¹ REATS is a strange acronym. Maybe a better name can be found. ;-)

Re: [coreboot] Regarding the timestamp in coreboot.

Dear Rajashaker welcome to coreboot!

What board do you use? Note, AMD AGESA boards currently do *not* support storing romstage time stamps, so they cannot be read out and are lost during the boot. Also remember that the payloads, at least GRUB 2, SeaBIOS and FILO, do not write store time stamps in CBMEM. There is also timing information, which coreboot only puts in its console log (`sudo ./cbmem -c`). Search for *BS:* and *usec* for example. Please report back, if that helped you. Thanks, Paul PS: The official spelling of the project name is *coreboot*, that means it’s one word.
