Board:lenovo/x60

Coreboot supports all variants of the ThinkPad X60 Series. (X60, X60s, X60 Tablet).

Aside from pre-sales configuration (display, processor speed, optional components) it looks like every X60 variant uses the same motherboard schematic.

Status

• Some ACPI issues with Windows needs to be fixed.
• Works well with GNU/Linux.
• The Wacom Digitizer now works on the X60 Tablet.

Installation and Flashing

Follow the tutorial below to install Coreboot on the ThinkPad X60 Series.

Wifi chipsets

Lenovo BIOS has a whitelist of approved PCI ID's for wifi cards. Coreboot does not, so you are free to use any wifi chipset of your choosing once coreboot is installed.

The Libreboot distribution lists Wifi chipsets not needing proprietary software to work.

proprietary components status

• CPU Microcode (optional?) - works fine without. See http://download.intel.com/design/mobile/SPECUPDT/30922214.pdf
• VGA option rom (optional): Native graphics initialization (free replacement) is also available and merged in the master repo. Note that the replacement doesn't work yet with seabios but works with grub(as a payload) or libpayload based payloads. SeaBIOS can be used with SeaVGABIOS (coreboot linear framebuffer option in seabios menuconfig) but the native graphics implementation currently lacks INT 10H and VBT.
• EC(Embedded Controller) => you do not have to touch it(just leave it where it is)

TODO

Non-free components replacements

• Replace the non-free VGA option rom by making native graphics init work. (native graphics available in master)
• Create a Native graphics<->VGA option rom. SeaVGABIOS (part of SeaBIOS) might be the answer. INT 10H and VBT are missing in native graphics.
• Make backlight work without the non-free option rom. See [1]

Windows currently doesn't boot (STOP A5 error)

Windows 7 was tested and fails to boot at the moment.

The native graphics implementation lacks INT 10H and VBT, and GRUB cannot boot it. Booting with SeaBIOS+SeaVGABIOS results in graphical corruption (and no boot).

Booting with SeaBIOS and the VGA ROM (vbios) can be used to boot it, but booting ends with the message outlined here: STOP A5

high pitched noise from the board during low power states

During low power state (cstate 3), a high-pitched "humming" noise eminates from the board. Some discussion has been made about this; suggestions include "using an oscilliscope in clever ways" (to detect where the noise is coming from to debug the issue). There are some workarounds:

Use "idle=halt" (higher power consumption) or "processor.max_cstate=2" (higher power consumption, but not as bad) kernel parameter in GRUB. These increase heat and power consumption.

Another option (for increased battery life and lower temperatures) is to use powertop --auto-tune, or set 'Tunables' in powertop (without any parameters).

Building without proprietary blobs

This basically means:

• No microcode updates
• Native graphics (replacement for the proprietary VBIOS / VGA Option ROM)
• GRUB2 payload

Download coreboot like usual:

git clone http://review.coreboot.org/coreboot
cd coreboot

At the time of writing for (for these instructions), the following git revision was used:

git reset --hard 9310df8d0351842e7bb9efe3cabc0ff82ec99c53

Apply the following patches in this order:

# Text mode patch for X60 native graphics (main patch already merged in coreboot. See 6723 on coreboot gerrit)
git fetch http://review.coreboot.org/coreboot refs/changes/25/6725/3 && git cherry-pick FETCH_HEAD

# If you want legacy brightness controls (if using this, make sure not to include the ACPI brightness patch below):
git fetch http://review.coreboot.org/coreboot refs/changes/48/7048/4 && git cherry-pick FETCH_HEAD

# OR if you want ACPI brightness controls (if using this, make sure not to include the legacy brightness patch above):
git fetch http://review.coreboot.org/coreboot refs/changes/31/6731/7 && git cherry-pick FETCH_HEAD
# Fix uneven backlight levels (for ACPI brightness controls):
git fetch http://review.coreboot.org/coreboot refs/changes/49/7049/1 && git cherry-pick FETCH_HEAD

# ACPI brightness patches above were abandoned due to Windows incompatibility. If you only want to use GNU/Linux, then it should work fine.

Now you will want this basic configuration:

    General setup / Expert mode = enable
    General setup / Local version string = 7BETC7WW (2.08 )
    Mainboard / Mainboard vendor = Lenovo
    Mainboard / Mainboard model = ThinkPad X60 / X60s / X60t
    Mainboard / ROM chip size = 2048 KB (2 MB)
    Mainboard / SMBIOS Serial Number = L3BH242
    Mainboard / SMBIOS Version Number = ThinkPad X60s
    Mainboard / SMBIOS Manufacturer = LENOVO
    Mainboard / SMBIOS Product name = 1702L8G
    Chipset / Include CPU microcode in CBFS = Do not include microcode updates
    Devices / Use native graphics initialization = enable
    Display / Keep VESA framebuffer = disable (disable for text-mode graphics, enable for coreboot vesa framebuffer)
        Libreboot provides this with text-mode enabled by default, but it automatically patches a copy of the config at boot time to enable coreboot framebuffer for a separate set of ROM images, in each machine.
    Generic Drivers / Digitizer = Autodetect
    Console / Send console output to a CBMEM buffer = enable
    Payload / Add a payload = An ELF executable payload
    Payload / Payload path and filename = grub.elf

Now go back into Devices:

    Devices / Run VGA Option ROMs = disable
    Devices / Run Option ROMs on PCI devices = disable

Note, the above assumes that you already built your grub.elf from source along with everything that you need. Building GRUB is not covered here.

Other things

• Add support for more batteries in ACPI.
• Make the wifi card and/or the laptop produce less heat.
• Sometimes some dock USB port aren't initialized => fix that
• Fix that warning:

[   14.566817] ACPI Warning: 0x00000400-0x0000041f SystemIO conflicts with Region \_SB_.PCI0.SBUS.SMBI 1 (20130117/utaddress-251)

By using that advise:

<phcoder> GNUtoo-x60: in this case it looks like same range is declared twice in DSDT/SSDT
