cbfstool without cloning the whole repos? Use this script for <4MB download
by Mike Banon 10 Mar '21

10 Mar '21

The original script has been created by my friend Ivan Ivanov aka qmastery [1] but I noticed that it doesn't work anymore - because a cbfstool got a lot more new dependencies: 4MB of sources, compared to the previous 2MB. Had to update this script heavily [2] and now it's working fine as of today.

EC config registers?
by crabstorage＠getbackinthe.kitchen 06 Mar '21

06 Mar '21

I've now run autoport to compare in tree T440P and stock bios. I didn't get as much output as expected and not as many differences save for one. In devicetree.cb there are changes to the config0-config3 registers. Is this notable and can it cause pcie issues? Also the subsystemid is listed for devices in autoport, is it superfluous or should I append it to the current devicetree? Autoport chip ec/lenovo/h8 # FIXME: has_keyboard_backlight, has_power_management_beeps, has_uwb register "beepmask0" = "0x00" register "beepmask1" = "0x86" register "config0" = "0xa7" register "config1" = "0x05" register "config2" = "0xa8" register "config3" = "0xc6" register "event2_enable" = "0xff" register "event3_enable" = "0xff" register "event4_enable" = "0xd0" register "event5_enable" = "0x3c" register "event7_enable" = "0x01" register "event8_enable" = "0x7b" register "event9_enable" = "0xff" register "eventc_enable" = "0xff" register "eventd_enable" = "0xff" register "evente_enable" = "0x9d" Tree chip ec/lenovo/h8 register "beepmask0" = "0x00" register "beepmask1" = "0x86" register "config0" = "0xa6" register "config1" = "0x0d" register "config2" = "0xa8" register "config3" = "0xc4" register "has_keyboard_backlight" = "1" register "event2_enable" = "0xff" register "event3_enable" = "0xff" register "event4_enable" = "0xd0" register "event5_enable" = "0x3c" register "event7_enable" = "0x01" register "event8_enable" = "0x7b" register "event9_enable" = "0xff" register "eventc_enable" = "0xff" register "eventd_enable" = "0xff" register "evente_enable" = "0x9d"

Running QEMU targets in Jenkins
by Julius Werner 04 Mar '21

04 Mar '21

I'm just curious... have we ever considered booting some of our QEMU targets as part of the Jenkins CI? I know they don't do a lot but they do cover some stuff (e.g. CBFS). I randomly happened to boot one of my in-flight patch trains on qemu-i440fx recently and discovered that I accidentally broke rmodule loading. Would be nice if Jenkins could just do that for you automatically. Just wanted to know whether this had been discussed before and people have come up with good reasons not to do it, or if it's just a matter of nobody had time to implement it yet. (And if someone wanted to implement it, what would be the best hook point? Put it into abuild?)

what are requirements for coreboot IOMMU support?
by ludphaeus 03 Mar '21

03 Mar '21

Hi I am trying to port a Haswell laptop and I would want it to have IOMMU support. My chipset supports VT-d but CPU does not. The official info from Intel says the PC needs chipset, CPU and BIOS to support VT-d to use IOMMU. I think this is not true because I saw some boards in board status have working IOMMU with no VT-d support in chipset but with coreboot advertising DMAR table to OS and CPU with VT-d support. Sapphire H61 is a example of this. But other H61 coreboot boards such as P8H61-M LX that have CPU without VT-d advertise no IOMMU capability. So what is really required for full IOMMU ? Do I have chance for full, working IOMMU on this laptop? Thanks, Lud

Display Port Monitor turns off during Ubuntu OS boot
by Rao G 03 Mar '21

03 Mar '21

Hi Coreboot Team, There is an external Monitor which works on HDMI/DVI and also DP , In BIOS the display is good whereas in OS (Ubuntu 18.04) until the kernel is initialized and i915 Video driver is loaded display is perfect, looks like the i915 OS driver switches off the monitor and there is no signal Does ACPI GFX method have to return any External display specific data to the OS driver ? Tried to make changes to VBIOS but did not help, thought ASL code is missing under GFX0 From the OS following data can be read 1. External Monitor's EDID data can be read from I2C Bus 2. Even VBT data from ACPI NVS can be read Tried to dig into some of these files https://github.com/torvalds/linux/tree/master/drivers/gpu/drm/i915/display intel_dp.c, intel_acpi.c to understand what function is turning off DP link when i have the OS debug driver logs, can send it across Any clues will help, appreciate your time PS:The platform has Intel BayTrail SoC, ValleyView chipset and VBIOS. The bios do not use GOP driver which replaces VBIOS Thanks Rao

Lenovo T410: Regression in coreboot 4.13?
by Daniel Kulesz 02 Mar '21

02 Mar '21

Hi folks, I spent a long time trying to get coreboot 4.13 to work on a Lenovo T410, trying various configuration options etc. but it never worked (fan, keyboard LED and thinklight went on, screen stayed dark). I tried even the most basic config, but no luck. I tried the same with coreboot 4.12 and this seems to work fine. Unfortunately, this is not my laptop and the owner needs his laptop back asap, so I don't have the time to further debug this issue. Yet, I wanted to report this regression as I I am wondering if anyone else is running 4.13 on a T410 with success? Cheers, Daniel

Question regarding reflashing/updating
by Louis 02 Mar '21

02 Mar '21

Hello, Just wanted to say thank you for creating this firmware it is a great project and I hope I can contribute to it one day. I have an x230 preinstalled with Coreboot skulls, am I able to re-flash Coreboot skulls internally just through the OS or is there a way to verify that the firmware installed on the system hasn't been modified in any way, thank you. Kindest regards, Louis
