HP Elitebook 8770w Suspend-to-RAM
by Robert Reeves 11 Jan '18

11 Jan '18

Hi, I'm working on porting coreboot to the elitebook 8770w, with the goal of submitting what I've come up with once I get it working the way it should. Hardware wise it's very similar to the EB 8470p which I based the port off of. Almost everything works right now, except for suspend to RAM (and grub, but I'll figure that out later). It goes into suspend fine, but on resume it simply restarts. I've never done this before and I don't really know what I'm doing. I've attached a log which includes serial output from both coreboot and debian over several power/suspend/resume cycles with every debug option I could think of turned on. I'm not sure what to look for, I see several error messages, but I'm having a hard time telling which ones are serious and which can be ignored. I would appreciate any help, and I would like to gain enough experience to be a regular contributor to this project. -Rob

Hi Hilbert. > The SeaBIOS .config is always been reset when I recompile the coreboot. I am trying to figure out how to avoid that. Just cd into the seabios-folder and make menuconfig. Save your config after modification. Now copy the resulting .config file somewhere (your coreboot directory for example). Now make menuconfig for coreboot and here, if you have selected SeaBIOS as payload, you can provide a .config file for SeaBIOS. Add the path to the saved .config file from SeaBIOS and you are good to go.

Hi Hilbert. It might be nothing but if I have a look at your last attached log I can't see SeaBIOS finding any USB devices. There is just one Error mentioned: >ehci_wait_td error - status=80e42 So what is special with SeaBIOS and Broadwell-DE: you have to unset the config switch called "CONFIG_MALLOC_UPPERMEMORY" in SeaBIOS config. With this option set SeaBIOS has issues with USB on Broadwell-DE. It might help you, just check it and give it a try if not unset already.

Hi Zoran, I have my USB stick formatted with ext4fs and I am pretty sure the image inside is bootable. What I mean to get a prompt shell is like following so that I can specify my commands. grub> linux (usb0,1)/bzImage console=ttyS1,115200 console=tty1 root=/dev/ra m ramdisk_size=102400 grub> initrd (usb0,1)/core-image-minimal-initramfs-mohonpeak64.cpio.gz grub> boot But right now it just hangs there and I am looking into GIPO settings or maybe I have some wrong settings in ACPI table:( -Hilbert This e-mail and its attachment may contain information that is confidential or privileged, and are solely for the use of the individual to whom this e-mail is addressed.

> 1. There is a 8GB DDR4 memory in my system. YUP, it is clearly visible from e820. I do not know too much about setup parameters for DDRs, so it is hard for me to get the DDRX (X) from MRC logs you have attached at the beginning of this email thread. I assumed DDR3. > 2.

It just depend how did you configure your Live Linux on your USB stick (should be MBR partition header, and probably USB stick should be formatted as ext4 or NTFS). Please, look here: https://rufus.akeo.ie/ . Please, note that on this figure: https://rufus.akeo.ie/pics/rufus_en.png partition scheme should be only MBR, and File System I use in legacy case is NOT FAT32, NTFS usually (maybe ext2 or ext4). Under these conditions, USB should show to you GRUB2 setup screen (my best guess).

Hi Zoran, 1. There is a 8GB DDR4 memory in my system. 2. I don't attach any HDD/SSD and I'll try to use Grub2 to access my kernel through USB interface. But I wish I can get shell prompt first before starting kernel. Suppose there should be a prompt for Grub2 or SeaBIOS, doesn't it? -Hilbert This e-mail and its attachment may contain information that is confidential or privileged, and are solely for the use of the individual to whom this e-mail is addressed.
