proprietary components status

  • CPU Microcode (optional?)
  • VGA option rom (optional): without it you will get no graphics during early boot, old kernel versions(like the one in trisquel 6) are able to initializes the intel graphic card. Note that the replacement doesn't work yet with seabios but works with grub(as a payload) or libpayload based payloads.
  • 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.
  • Create a Native graphics<->VGA option rom.
  • Make backlight work without the non-free option rom.

Other things

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

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:

cbmem console

To get cbmem console working you need the non-free i915 option rom or native graphics(doesn't work yet, don't use). Even with a dummy VGA option rom it fails:

[root@X60 cbmem]# ./cbmem -c -VVV
Looking for coreboot table at 0

[root@X60 cbmem]# dmesg -c
[26300.943482] Program cbmem tried to access /dev/mem between f0000->1f0000.

Using fmem doesn't work either:

[root@X60 cbmem]# ./cbmem -c -VVV

Howto

Go in console:

Console  --->

Enable it:

[*] Send console output to a CBMEM buffer
(0x10000) Room allocated for console output in CBMEM
(0xc00) Room allocated for console output in Cache as RAM

thinkpad_acpi compatibility

The following commit might be interesting to cherry-pick:

git fetch http://review.coreboot.org/coreboot refs/changes/03/3403/3 && git cherry-pick FETCH_HEAD

Dmidecode from the BIOS says:

BIOS Information
	Vendor: LENOVO
	Version: 7BETC7WW (2.08 )

So in make menuconfig go in

General setup  --->

And modify Local version string accordinly

(7BETC7WW (2.08 )) Local version string

Then locate the following in dmidecode:

System Information
	Manufacturer: LENOVO
	Product Name: 1707Y8W
	Version: ThinkPad X60
	Serial Number: L3BY949

Then in

Mainboard  --->

do that:

(L3BY949) Serial number
(ThinkPad X60) Version number
(LENOVO) BIOS table vendor string
(ThinkPad X60 / X60s) BIOS table part number string

Then configure and build coreboot as usual

To modprobe the module use that:

modprobe thinkpad_acpi force_load=1 debug=0xffff fan_control=1 experimental=1

The module should now load automatically...
