Board:lenovo/x60

works fine with Linux, some ACPI issues with Windows needs to be fixed.

Lenovo ThinkPad X60

Except where noted all status items apply to:

• x60
• x60s
• x60 tablet

Aside from pre-sales configuration (display, processor speed, optional components) the three models appear identical. It is believed that they share a single schematic.

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. submited for review. (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 6731 on review.coreboot.org

Enable backlight controls on X60 (with native gpu init instead of VGA ROM)

See x60 notes and t60 notes.

This is one way to get backlight controls working. Another method is shown in changeset 6731 on review.coreboot.org.

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

Features

nvramtool

Without the VGA optiorn rom nvramtool says:

# ./nvramtool -a
nvramtool: coreboot table not found.  coreboot does not appear to
        be installed on this system.  Scanning for the table produced the
        following results:

            0 valid signatures were found with bad header checksums.
            0 valid headers were found with bad table checksums.

Fortunately there is a workarround:

# ./nvramtool -y ../../src/mainboard/lenovo/x60/cmos.layout -a
boot_option = Fallback
last_boot = Fallback
baud_rate = 115200
debug_level = Emergency
hyper_threading = Enable
nmi = Disable
# Bad value -> boot_devices
boot_default = 0x40
cmos_defaults_loaded = Yes
lpt = Disable
volume = 0xc
tft_brightness = 0xf
first_battery = Primary
bluetooth = Disable

"whining" (buzzing) noise when idle

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

Note: Boot without these options, and there will be a high pitched noise coming from the board when the system is idle. A better workaround is to boot without these options, and run sudo powertop --auto-tune

Alternatively run powertop without arguments. Under "tunables", set all options to "Good" settings. This kills the noise. By using this, power consumption falls lower: near the levels in Lenovo BIOS (better battery life).

cbmem console Howto

When configuring coreboot with "make menuconfig" Go in console:

Console  --->

Enable it:

[*] Send console output to a CBMEM buffer
(0x20000) Room allocated for console output in CBMEM
(0xc00) Room allocated for console output in Cache as RAM
