[coreboot] Does S3 work on Haswell boards?

I don’t think that the problem is connected to operating system version as both Windows 7 and Ubuntu 16.04 act the same for me:
- for S3 time less than ~15s, resume works ok
- for S3 time longer than ~15s, Coreboot won't resume with quick_ram_check error

I use “pm-suspend” to go to S3, but “systemctl suspend” works exactly the same. USB wakeup doesn't work at all for me. I wake system with power button.

Hello Kostja,

Since presently I am not in Munich/Germany (I am in front of my HSW notebook in my apartment in Belgrade), I have limited abilities to test your question, since I do not have native/bare metal Fedora on my SSD (I have in safe box HDD with dual boot: WIN10 and Fedora 26 in Munich).

Here, I have my notebook (HP EliteBook 840 G1) with SSD, bare metal WIN10 64 PRO and VMWare reader with Fedora 26 VM. IT is based on HSW i5-4300:
[user at 192 ~]$ dmesg | grep 4300
[    0.097524] smpboot: CPU0: Intel(R) Core(TM) i5-4300U CPU @ 1.90GHz (family: 0x6, model: 0x45, stepping: 0x1)
[user at 192 ~]$

Here is the pointer to ark.intel.com for this CPU: https://ark.intel.com/products/76308/Intel-Core-i5-4300U-Processor-3M-Cache-up-to-2_90-GHz

The current BSP used is UEFI: BIOS 01.39 Rev.A (08 Nov 2016) -> sp77791.exe (12.7 MB)
_______

Being in WIN10, suspend works when I simply press <F3>, but resume works ONLY while I press muse buttons - keyboard <ANY KEY> does not work, although it should?!

I did several attempts to suspend and resume using Fedora 26 VM, but I did not have success. I do remember that this does work with my bare metal Fedora 26:
Kernel used for Fedora26 VM: uname -r -> 4.13.9-200.fc26.x86_64 .

I would strongly suggest to use two methods to check S3 on Linux bare metal:
[1] To use systemctl suspend and systemctl resume commands;
[2] To install on your HSW platform the following package: http://www.linuxfromscratch.org/blfs/view/cvs/general/pm-utils.html
      so you can try the following two commands: pm-suspend and pm-hibernate (wakeup should work using keyboard/mouse)!

First, you should do all these tests with UEFI BIOS for your platform, record the results, and then switch to Coreboot, than repeat all use cases, and cross compare.

If you do, please, post your kernel version and results here.

Hope this helps.

Best Regards,
Zoran Stojsavljevic

I've enabled mrc.cache and ME in coreboot. I use ME binary from original

It seems like DRAM controller and ME are initialized correctly (like in
normal boot), what can be wrong?

Does S3 work on Haswell boards?
