This page describes how to use coreboot on the Lenovo G505S mainboard.

This page is a work in progress. ACPI is still being worked on, however due to the nature of ACPI it may take some time to get this right.

Known Issues

  • S3 Suspend/Resume - You will need a Console verbosity set to at least "BIOS_INFO" or greater for it to work! Coreboot is likely too fast for the Embedded Controller firmware on the S3 resume hot path.
  • S3 Suspend/Resume - Nasty looking dmesg messages seen in Note 2. LKML bug report force_ibs_eilvt_setup().
  • "AGP: Please enable the IOMMU option in the BIOS setup" showing up in dmesg - Pass iommu=noaperture to the kernel boot args to ask the IOMMU not to touch the aperture for AGP.
  • "Re-enabling disabled Topology Extensions Support" showing up in dmesg - See Note 1.

Note 1: Look in src/vendorcode/amd/agesa/f15tn/Proc/CPU/Family/0x15/TN/F15TnMsrTables.c for 

 if (PkgType == PACKAGE_TYPE_FM2) {
    CpuMsrData |= BIT54;
 }

this is the wrong package type for us. Fixed in 7671


Note 2: Look in src/vendorcode/amd/agesa/f16kb/Proc/CPU/Family/0x16/KB/F16KbMsrTables.c and src/vendorcode/amd/agesa/f15tn/Proc/CPU/Family/0x15/TN/F15TnMsrTables.c Backport fixes that pertain to MSR 0x00000413' and MSR 0xC0000408. The following in seen in dmesg on S3 resume: 

[  396.828594] [Firmware Bug]: cpu 0, try to use APIC500 (LVT offset 0) for vector 0xf9, but the register is already in use for vector 0x400 on another cpu
[  396.828596] [Firmware Bug]: cpu 0, failed to setup threshold interrupt for bank 4, block 0 (MSR00000413=0xc000000001000000)
[  396.828597] [Firmware Bug]: cpu 0, try to use APIC500 (LVT offset 0) for vector 0xf9, but the register is already in use for vector 0x400 on another cpu
[  396.828599] [Firmware Bug]: cpu 0, failed to setup threshold interrupt for bank 4, block 1 (MSRC0000408=0xc000000001000000)

Overview

Hardware

  • AMD A-series AMD A10-5750M APU
  • AMD AGESA Hudson part of the chipset, AMD AGESA Hudson southbridge
  • ENE KB9012 EC However we use the ENE932 EC driver in coreboot's tree.

Details

...

  • 1x MXIC MX25L1606E (SO8, soldered) 16 Mbit SPI flash (BIOS)

Building a coreboot image

Make a fresh clone of Coreboot into a empty directory and run: 

make crossgcc-i386

Make a cup of tea.. Then run: 

make menuconfig

and select Lenovo/G505S under "Mainboard -> Mainboard vendor/model" leaving everything else as defaults. Then finally do, 

make

To flash the board with flashrom externally run: 

flashrom -p ft2232_spi:type=2232H,port=A -w build/coreboot.rom

and internally run: 

flashrom -p internal:laptop=force_I_want_a_brick -w build/coreboot.rom
