==== VGA Option ROM / VBIOS replacement (native graphics) ====
 
The [[VGA_support|VGA option ROM]] is proprietary. If you have an X60,X60s or X60t, GNUtoo (et al) has developed a free replacement which is under review, but you can use it right now:

== Enable backlight controls on X60 (with native gpu init instead of VGA ROM) ==
 
 
It was discovered that while this code seems to work fine on kernels older than linux 3.12.
 
 
 
On 3.12 and later kernels the i915 driver became unstable. Causing broken/glitchy 3D. and performance bugs.
 
 
 
The current suspicion is that linux had a bug which caused it to miss stolen memory altogether on this machine and hence disable parts of code.
 
This bug was corrected in:
 
[https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=17fec8a08698bcab98788e1e89f5b8e7502ababd 17fec8a08698bcab98788e1e89f5b8e7502ababd]
 
 
 
Which was identified by git bisect, to be the cause of the driver crashes using native vga on the x60.
 
 
 
The native vga init code in coreboot needs to be corrected to have more engineered memory management.
 
In the interim users have attempted running patched linux 3.12 kernels which revert commit 17fec. To apparent success.
 
  
Reported upstream in the Freedesktop Bugzilla as [https://bugs.freedesktop.org/show_bug.cgi?id=79038 ticket #79038][https://01.org/linuxgraphics/documentation/how-report-bugs How to file a good bug report?].

Revision as of 08:47, 23 September 2014

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.

Installation and Flashing

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
