It covers configuring the Linux kernel for the hardware of the X31 and setting up X11 for the Radeon graphics chipset. The Docbook XML source from which it was created is available as well. The latest version of this document can be obtained from www.brixandersen.dk.

This document describes my experiences with configuring GNU/Linux to run on the X31. The document covers how to set up the kernel for the specific hardware found in the X31 and how to set up the graphical user interface, X11. A certain amount of experience with kernel configuration and X11 is required. Although the instructions in this document are based on my experiences with Gentoo Linux it should be fairly trivial to use them with any other Linux distribution. I've tried to be as general as possible and left out distribution specific instructions.

This section describes how to configure a Linux kernel version 2.6.x for the hardware found in the X31. The instructions found in this revision of the document has been tested with linux-2.6.15. Only options closely related to the X31 specific hardware are mentioned; which options to enable apart from those is beyond the scope of this document. The kernel options which I have chosen to build as modules are marked with [module]. My main reasons to compile certain functionality as modules is to enable run-time configuration through module parameters and to be able to only load a module when that particular functionality is needed. My latest kernel .config file can be found at my web site.

Kernel support for the Pentium M CPU and the Centrino chipset of the X31 is enabled through the kernel options listed below. Subarchitecture Type (PC-compatible) (CONFIG_X86_PC) Processor family (Pentium M) (CONFIG_MPENTIUMM) Machine Check Exception (CONFIG_X86_MCE) MTRR (Memory Type Range Register) support (CONFIG_MTRR) PCI support (CONFIG_PCI) ISA support (CONFIG_ISA) ATA/ATAPI/MFM/RLL support (CONFIG_IDE) Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support (CONFIG_BLK_DEV_IDE) Include IDE/ATA-2 DISK support (CONFIG_BLK_DEV_IDEDISK) PCI IDE chipset support (CONFIG_BLK_DEV_IDEPCI) Sharing PCI IDE interrupts support (CONFIG_IDEPCI_SHARE_IRQ) Generic PCI bus-master DMA support (CONFIG_BLK_DEV_IDEDMA_PCI) Use PCI DMA by default when available (CONFIG_IDEDMA_PCI_AUTO) Intel PIIXn chipsets support (CONFIG_BLK_DEV_PIIX)

The SMBus of the X31 is supported by the kernel options listed below. Since the only devices connected to the SMBus are the DIMM EEPROMS, it's not of much use. I2C device interface (CONFIG_I2C_CHARDEV) Intel 801 (CONFIG_I2C_I801) Due to some rather nasty accidents with SMBus access on IBM ThinkPads in the past I recommend not fiddling with it unless you know what you are doing.

The X31 is equipped with an ATI Technologies Inc. Radeon Mobility M6 LY graphics chipset. The kernel has support for a high resolution framebuffer console on the Radeon chipset and a direct rendering manager which improves the performance of OpenGL 3D applications under X11. Frederick Dean has written a small utility called radeontool which can be used for controlling the Radeon graphics chipset.

To enable the high resolution framebuffer console you need the kernel options mentioned below. Support for frame buffer devices (CONFIG_FB) ATI Radeon display support (CONFIG_FB_RADEON) Video mode selection support (CONFIG_VIDEO_SELECT) Framebuffer Console support (CONFIG_FRAMEBUFFER_CONSOLE) To actually use the high resolution framebuffer you need to pass a video= option to the kernel at boot time like the one shown in . For more information see the documentation for the kernel and your boot loader.

video=radeonfb:1024x768-32

To enable the direct rendering manager you need the kernel options listed below. The X11 specific configuration is covered in . /dev/agpgart (AGP Support) (CONFIG_AGP) Intel 440LX/BX/GX, I8xx and E7x05 chipset support (CONFIG_AGP_INTEL) Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) (CONFIG_DRM) ATI Radeon (CONFIG_DRM_RADEON)

You have two choices when it comes to power management for the X31: the older Advanced Power Management (APM) or the newer Advanced Configuration and Power Interface, (ACPI).

Power Management support (CONFIG_PM) APM (Advanced Power Management) BIOS support (CONFIG_APM) Enable PM at boot time (CONFIG_APM_DO_ENABLE) Make CPU Idle calls when idle (CONFIG_APM_CPU_IDLE) Enable console blanking using APM (CONFIG_APM_DISPLAY_BLANK) RTC stores time in GMT (CONFIG_APM_RTC_IS_GMT) Allow interrupts during APM BIOS calls (CONFIG_APM_ALLOW_INTS)

You can make the X31 enter standby mode by pressing Fn+F3. Pressing Fn+F4 will make the X31 suspend to RAM. You can use the tphdisk utility to create a save2dsk.bin hibernation file on a primary, hidden FAT16 partition. You should then be able to make the X31 suspend to disk by pressing Fn+F12.

To use ACPI you will need the kernel options listed below instead of the ones listed in . You will also need acpid, the Linux ACPI Daemon. Power Management support (CONFIG_PM) Sleep States (CONFIG_ACPI_SLEEP) ACPI Support (CONFIG_ACPI) AC Adapter (CONFIG_ACPI_AC) Battery (CONFIG_ACPI_BATTERY) Button (CONFIG_ACPI_BUTTON) Processor (CONFIG_ACPI_PROCESSOR) Thermal Zone (CONFIG_ACPI_THERMAL) IBM ThinkPad Laptop Extras (CONFIG_ACPI_IBM) [module] Power Management Timer Support (CONFIG_X86_PM_TIMER)

You can make the X31 enter standby mode using the command echo -n standby > /sys/power/state. To make the X31 suspend to RAM you use the command echo -n mem > /sys/power/state. Suspend to disk under ACPI can be achieved using the kernel options listed below. You should then be able to make the X31 suspend to disk using the command echo -n disk > /sys/power/state. Power Management support (CONFIG_PM) Software Suspend (CONFIG_SOFTWARE_SUSPEND) To tell the kernel which swap partition to read the memory dump from at boot time you need need to pass a resume= option to the kernel like the one shown in . For more information see the documentation for the kernel and your boot loader.

resume=/dev/hda2

To enable the dynamic frequency scaling of the Centrino chipset you need the kernel options listed below. The CPU frequency can then be adjusted through the /sys/devices/system/cpu/cpu0/cpufreq/ interface. You will need a user-space utility such as cpufreqd if you wish to automate the frequency. CPU Frequency scaling (CONFIG_CPU_FREQ) 'performance' governor (CONFIG_CPU_FREQ_GOV_PERFORMANCE) 'powersave' governor (CONFIG_CPU_FREQ_GOV_POWERSAVE) 'userspace' governor for userspace frequency scaling (CONFIG_CPU_FREQ_GOV_USERSPACE) 'ondemand' cpufreq policy governor (CONFIG_CPU_FREQ_GOV_ONDEMAND) CPU frequency table helpers (CONFIG_CPU_FREQ_TABLE) Intel Enhanced SpeedStep (CONFIG_X86_SPEEDSTEP_CENTRINO) If you use ACPI, you will need the kernel options listed below as well.

To use the FIR port, a Fast Infrared port, of the X31 you need at least the kernel options listed below. You may want to enable higher level IrDA protocols such as the IrCOMM protocol (CONFIG_IRCOMM) which implements serial port emulation. You will need the irda-utils software package from The Linux IrDA Project. IrDA (infrared) subsystem support (CONFIG_IRDA) [module] NSC PC87108/PC87338 (CONFIG_NSC_FIR) [module] To have the kernel module recognize the hardware correctly you need to add the contents of to /etc/modules.conf.

alias irda0 nsc-ircc options nsc-ircc dongle_id=0x9

You will need to execute the command irattach irda0 to set up the infrared port. If you have enabled 8250/16550 and compatible serial support (CONFIG_SERIAL_8250) in the kernel you may have to add the line pre-install nsc-ircc /bin/setserial /dev/ttyS1 uart none to /etc/modules.conf to disable the serial driver for the infrared port.

To enable the parallel port of the X31 you will need the kernel options listed below. Parallel port support (CONFIG_PARPORT) [module] PC-style hardware (CONFIG_PARPORT_PC) [module] To have the kernel module automatically loaded when needed you should add the contents of to /etc/modules.conf.
