Toshiba Tecra S4
Model No. PTS40E-01K00JGR
SERIAL No. 27056280H
Dear ladies and gentlemen,
I could compile coreboot. A test with qemu, as described in coreboot -
lesson 1
was successful. But this configuration with mainboard = emulation is for
demon-
stration only, isn't it ? I did not find the toshiba mainboard. If it is
possible, please
give me some tips, how I can continue, because for me this is untouched
land.
Because of the fact, that this is an old laptop with many security
elements and a
separate password chip, would you say, let it be ?
Yours sincerely

Hi,
I'm trying to boot Windows 10 with Coreboot 4.9.2002 using Tianocore + a PCIe GPU and I always get an strange ACPI_BIOS_ERROR.
Without the PCIe GPU, works ok.
I'm pretty sure is an error with my DSDT or the southbridge code.
Sadly, I cannot debug Windows to know determine the exact ACPI problem.
I also tested with other boards like the Asus Maximus IV GeneZ and the problem is there too: with the IGP only works, but when I attach a PCIe GPU then it crashes.
Take a look to my code if you want, any help about this will be welcome.

Thanks.

Do you have something crazy going on and want to present it to the
community?
Submit your talk for the Open Source Firmware conference 2019 in silicon
valley until June 30, 2019.
Speakers get complimentary admission to the conference.
We also have scholarship funds to help you attend the conference.
We will have three tracks:
1) Open Source Firmware Main Track
2) Security Track
3) Baseboard Management Controllers (BMC) Track
as well as lightning talks during the hackathon
So just go ahead and participate on the OSFC 19: https://osfc.io/speakers
See you in California in September."
Cheers,
Zaolin

Hi,
We have "#ifdef LONG_FADT" at line #36
however, that LONG_FADT is not used at all
"git grep -r LONG_FADT" gives only 2 places:
src/southbridge/nvidia/ck804/fadt.c:#ifdef LONG_FADT
src/southbridge/nvidia/ck804/fadt.c:#ifdef LONG_FADT
Do you have any idea about LONG_FADT ?
can we drop it?
also, the line : header->length = 0x74 looks "wrong", we currently are using FADT revision 3.
Thx

Yes microcode updates are included.
Thats really interessting.
I can try to build one without microcode ... but as i am using an
Opteron 6380 i will need the microcode in some way.

Hello!
Please, someone tell me, why SeaBIOS changing e820 memory map for 0x100000 - 0x7ff2dfff region? For example:
Jun 4 21:41:31 tp0 kernel: [ 0.000000] BIOS-e820: [mem 0x0000000000100000-0x000000007ff2dfff] usable

This interrupts the boot from hibernation:
tp0 kernel: [ 6.241612] Hibernate inconsistent memory map detected!
tp0 kernel: [ 6.243876] PM: Image mismatch: architecture specific data
tp0 kernel: [ 6.246132] PM: Read 3253276 kbytes in 0.01 seconds (325327.60 MB/s)
tp0 kernel: [ 6.248816] PM: Error -1 resuming
tp0 kernel: [ 6.248852] PM: Failed to load hibernation image, recovering.
OS Debian testing
Linux tp0 4.19.0-5-amd64 #1 SMP Debian 4.19.37-3
Thinkpad T420 with IvyBridge i5-3380M

Thanks!

There is motherboard based on the Intel Rangeley Atom C2000 (C2758) series processor. How to enable the SMBus0 in coreboot? If I use OEM BIOS or BIOS from Intel (EDVLCRB1.86B.0048.R00.1508181657_MPK) for mohon peak crb, then I see on the SMBus0 (i2c-1 in Fedora 28) memory DIMM spd (0x50 & 0x52), clock generator (0x69) and other devices. If I use a coreboot based bios for the Mohon peak platform - I do not see any devices on i2c-1. I see an data exchange on the SMBus0 with oscilloscope at boot time only. When I send "i2cdetect -y 1" command in Linux no activity on SMBus0 and no device found.
