Some information from emperorlinux

[edit] Processor

 driver: centrino
 hardware limits: 800 MHz - 1.60 GHz
 available frequency steps: 1.60 GHz, 1.33 GHz, 1.07 GHz, 800 MHz
 available cpufreq governors: conservative, ondemand, powersave, userspace, performance

(of course this is for a Sony Vaio S4/M. Different models mount different processor, 1.73 Ghz etc. But since they are all pentium-m the configuration is just the same)

So you can put in your make.conf

CFLAGS="[...] -march=i686 [...]"
USE="[...] sse sse2 mmx mmxext[...]"

with gcc >= 3.4 you can try -march=pentium-m

edit: xushi.

After reading gcc's man pages, i've safely used the following CFLAGS for the past year with very good results. make.conf

CFLAGS="-O2 -march=pentium-m -pipe -fomit-frame-pointer -ftracer -fweb"

WARNING: some of the cflags reported above (like funroll-loops) can lead to serious problems. Don't use them if you don't know what you are doing. A set of more conservative and safe CFLAGS are reported in this howto: I strongly recommend not to experiment if you don't know exactly what those flags do, be on the safe side. For gcc 3.4 and later use:

CFLAGS="-march=pentium-m -O2 -pipe -fomit-frame-pointer"

[edit] Disk

description: SCSI Disk
product: FUJITSU MHT2060B
vendor: ATA
physical id: 0.0.0
bus info: scsi@0:0.0.0
logical name: /dev/sda
version: 4000
size: 55GB
configuration: ansiversion=5

N.B. At the moment the stable hdparm (5.9) does not support SATA disks. The ~x86 masked hdparm (6.3) does support SATA disks and with the suspend2-2.6.15 sources it works out of the box. See the gentoo power management guide for more info on how to get the disks to spin down when on battery.

There is a big (10GB) recover partition at the beginning of the disk. Make recover DVDs from Vaio Recover Utility in Win and wipe it, if you want. I did. Just remembered, the bootable restore DVD is actually the *second* you burn.

[edit] Frame buffer

At the moment I'm using gentoo-sources-2.6.12-r9 and splashutils-1.1.9.9. I could not manage to get the 1280x800 framebuffer, so I stay with 1024x768 (vga=791). vesafb-tng is doing strange things with my display, so I stayed with vesafb. To set up the whole thing just follow HOWTO gensplash. Do not enable FB_NVIDIA, it conflicts with X nvidia drivers.

[edit] Nvidia 3D Acceleration

Nvidia 6200 Turbocache and a 13.3 TFT widescreen.

Note: Should any problems arise, please visit The Nvidia Guide and follow it through. Your kernel needs to be configured for AGP support.

As of October 2006, Gentoo changed the location in portage of the nvidia drivers from nvidia-glx / nvidia-kernel to x11-drivers/nvidia-drivers. To install the 3D accelerated nvidia drivers, you will need the following packages.

app-admin/eselect
app-admin/eselect-opengl
x11-drivers/nvidia-drivers 

I recommend the latest versions of them. To unmask, add them to /etc/portage/package.keywords and emerge them as follows,

echo "x11-drivers/nvidia-drivers ~x86" >> /etc/portage/package.keywords
echo "app-admin/eselect-opengl ~x86" >> /etc/portage/package.keywords
echo "app-admin/eselect ~x86" >> /etc/portage/package.keywords

emerge -avt eselect eselect-opengl nvidia-drivers

Note: I (xushi) successfully use the 1.0.8776 drivers with very good results (~2000fps on full resolution). the 8774, has also been tested, and the masked beta 1.0.9626 work well too.

Note: I (moment) could only use the 1.0.9639 and prior drivers. More recent drivers break X when I switch to other terminals (CTRL+ALT+F1) or when the system reboots or shuts down.

When installed, you'll need to switch from the xorg-x11 libraries to the nvidia ones. To display what drivers you have, run the command

eselect opengl list

and you should get an output similar to this

xushitop # eselect opengl list
Available OpenGL implementations:
  [1]   nvidia 
  [2]   xorg-x11 *

The star ( * ) indicates which driver you are currently using. To switch, simply type the command,

eselect opengl set nvidia

Please read the X Configuration section below in order to use the drivers in your desktop environment. You will not be able to use them unless you edit your xorg.conf file.

Comment added by Massimiliano Adamo (5 August 2006): You may think that the monitor is too small and stretched, in this case you'll like Twinview, to have a dual monitor. The second monitor in this case must stay at the left of your notebook, and the total resolution is the addition of the single resolutions (in this case they differ). The second monitor is called here "CRT-0" (it's a huge old monitor, around 21 inches, made by Sun. You may need to tune only these parameters to fit your monitor)

These are the relevant sections from my xorg.conf:

       Identifier  "Videocard0"

       EndSubSection

To make the touchpad work we need synaptics drivers,

emerge x11-drivers/synaptics

You also need to have the following enabled in the kernel. "evdev" (CONFIG_INPUT_EVDEV=y)

 Device Drivers -> Input Device Support -> Event Interface (Y)

and "psmouse" (MOUSE_PS2=y)

Device Drivers -> Input Device Support -> Mouse -> PS/2 Mouse (Y)

Have a look also at gksyn and syndaemon to disable the touchpad when typing. See also the Synaptics Touchpad howto

Note: media-video/nvidia-glx-1.0.7676-r1 installs X's modules in /usr/lib/xorg/modules instead of /usr/lib/modules as expected. If X isn't able to find the nvidia driver, add the following line in the "Files" Section.

      ModulePath "/usr/lib/xorg/modules"

[edit] Networking

[edit] Ethernet

Enable the Intel(R) PRO/100+ Support driver (CONFIG_E100=y) in your kernel.

Device Drivers -> Network device support -> Ethernet (10 or 100Mbit) -> Intel(R) PRO/100+ Support (Y)

If you put it as module remember to echo "e100" >> /etc/modules.autoload/kernel-2.6

[edit] Wireless

For wireless you need to compile the ipw2200 driver as module you need the driver as module since it can only load the firmware if the filesystem was mounted before.

     Selects: FW_LOADER && IEEE80211   

You also need the firmware:

ipw2200-firmware

 emerge -av net-wireless/ipw2200-firmware

If you have a problem in loading the firmware simply add a rule for udev by:

echo 'ACTION=="add", SUBSYSTEM=="ipw2200", RUN+="/sbin/firmware_helper"' >> /etc/udev/rules.d/25-lfs.rules

[edit] Sound

Yes, the sound is really poor. But anyway we want it working. So enable

Symbol: SND_HDA_INTEL [=m]
   Prompt: Intel HD Audio
   Defined at sound/pci/Kconfig:517
   Depends on: !M68K && SOUND!=n && PCI && SND
   Location:

           -> Advanced Linux Sound Architecture (SND [=m])
             -> PCI devices
   Selects: SND_PCM

and edit

alias snd-card-0 snd-hda-intel

then rc-update add alsasound default If you prefer using alsa-driver then edit

ALSA_CARDS="hda-intel"

It seems (tested!) that by adding

options snd-hda-intel position_fix=1

(remember to run modules-update after any changes) you get better results (no crackling and more volume). Try also with position_fix=2. But to do this you need ~x86 alsa-drivers, since hda-intel is quite new and still under development.

With oss emulation, you can get a cleaner sound but volume is a bit low.

[edit] DVDRW drive

To get some more control on it download and install sony_acpi. Check your /proc/acpi for the new entries it creates. You'll have a cd_power read/write one. (CDPW/GCDP acpi method). The drive is region locked (MATSHITA UJ-832D). There is no region free firmware yet, check [1]. The latest firmware is 1.03 and is available as a download from Sony's support website.

To activate DMA (useful to read dvd, otherwise it may be slow) you need build in (not as module) PIIX Support.

CONFIG_BLK_DEV_PIIX=y

Enjoy a dvd in mplayer using all our screen by adding

monitoraspect=16:10

[edit] ACPI

[edit] general ACPI

Sony will not release the BIOS flash image as updates, I asked. So, the only way to update the BIOS as of now is via Windows, a DOS bootdisk won't help here. Also, pnxdeco cannot extract the flash image from the .exe There are no visible improvements gained through updating with the current .exe

Enable ACPI in your kernel configuration

and read your temperature from /proc/acpi/thermal_zone/ATF0/temperature If you want to be sure to get all acpi functionality add to your kernel line

acpi_os_name="Windows 2001 SP1"

this info is taken directly from the DSDT. (By the way, the dsdt compiles cleanly) (J.Jordens: I have not seen that the acpi_os_name enables special windows-only functionality, from the DSDT is seems to simply be a rewriting of sorts)

[edit] Suspend to disk/ram

[edit] Suspend to disk (S4) with suspend2-sources

• Using the suspend2-sources-2.6.15-r4 kernel and the latest nvidia drivers (1.0.8756) suspend to disk works perfectly (confirmed!). I followed the nvidia readme and did the following (you can add it to /etc/conf.d/local.start so it gets issued every boot):

 echo 0 > /proc/suspend2/extra_pages_allowance

• software suspend
  • Use 2.6.13-rc4 and the acpi 20050708.patch or the vanilla 2.6.15.1 kernel. swsusp works well on AC and Battery
  • laptop mode mustn't control the disks, disable that in the config
• Disable agpgart and dri, do not use libata.atapi_enable=1 as a kopt. irqpoll *can* help but is flaky
• Suspend To Ram (S3)
• suspend to ram does not work yet under X with nvidia, under the console it works.
• The garbled VT's are caused by the graphics card's registers getting junked while resuming.
• If you would like to see ongoing or previous tests with various kernels, please go to [2]. In any case, use the kernel mentioned above for the best results.
  • Using 2.6.15.1 I managed to get a kind of S3 resume. Everything works well until one tries HD access which hangs the process. These errors have all to do with libata's power management features. There are a bunch of patches for this floating around and 2.6.16-* has most of them included.

Further, I very much doubt this has anything to do with the DSDT - it compiles cleanly and there is no Windows-only functionality in it

• This is for a FS660 but perhaps someone could try fixing the DSDT for the S4 and seeing if the fixed DSDT fixes the S3 suspension [3]
  • Pay close attention to any missing PDC0 and PDC1 external() calls. After reading the ACPI specs I'm fairly certain this was the problem with the FS660s.

• Has anyone tried this solution? http://beyondabstraction.net/sonyfs660/#acpi

• Just a note, suspend-2-ram works out the box using "klaptop_acpi_helper --suspend " (included with one of the kde packages)

with the default hibernate-ram script and settings for me on an sz340 (which seems to have very similar hardware). This is using the 2.6.19-r3 suspend2-sources in portage. However, the console gets garbled upon resume. Not a problem if you only use X though.

• using nvidia-drivers-1.0.9639, suspend2-sources-2.6.22-r2 and hibernate-script-1.95-r2 both suspend to ram and disk work flawlessly! a working kernel config can be found here: [4]

[edit] Undervolt/Underclock

[edit] Processor

• On working, basically modify speedstep-centrino.c

On Windows I can run smoothly with 0.700 V @ 800 Mhz (6x) and 0.908 @ 1600 Mhz (12x). On linux I have 0.748 @ 800 or I get a freeze.

• an interesting patch Non tested

I actually tested it... my laptop works with 700mv @ 800 Mhz without any problems...but the fan still runs quite often....

[edit] Graphics Card

It's now possible to underclock the GPU/Memory using nvclock cvs. Download/compile and then

cd src
./nvclock -s
Card:           nVidia Geforce Go 6200
Card number:    1
Memory clock:   598.500 MHz
GPU clock:      300.857 MHz

./nvclock -m 200 -n 100 -f
Requested memory clock:         200.000 MHz
Requested core clock:           100.000 MHz

Adjusted low-level clocks on a nVidia Geforce Go 6200
Memory clock:   200.812 MHz
GPU clock:      99.000 MHz

Lower values give screen problem (lines/blur etc) for me.
N.B. I've not noticed any significant increase of battery life or some less heat.

[edit] LCD Brightness

The brightness isn't acpi governed, but it uses something in nvidia interface. The latest version (0.8 beta) nvclock supports it (thanks to Erik Waling!).

nvclock -S 40%

[edit] Fn keys

The method below is not needed any more since Sonypi now sends normal ACPI events so you can use acpid. But sonykeyd somehow seams much more responsive...

The kernel patch is included in the kernel since 2.6.14. If you want to use an older version you need to patch manually, see the history of this page. To make them work you need to configure sonypi, read the doc ( /usr/src/linux/Documentation/sonypi.txt), but mainly you need to add the following to /etc/modprobe.conf:

alias char-major-10-250 sonypi
options sonypi minor=250 fnkeyinit=1

and execute the following commands:

mknod /dev/sonypi c 10 250
modules-update

Then set SONYPI (-> Device Drivers -> Character devices) in kernel as module and

make modules modules_install

Then you need some kind of daemon to grab the keys and do something. I've "upgraded" for our Vaio a quite old project, sonykeyd, you can get the ebuild here (copy&paste). Put it in $PORTDIR_OVERLAY/app-laptop/sonykeyd:

mkdir $PORTDIR_OVERLAY/app-laptop/sonykeyd
mv sonykeyd-$version.ebuild $PORTDIR_OVERLAY/app-laptop/sonykeyd

and remember to regenerate the digest:

cd $PORTDIR_OVERLAY/app-laptop/sonykeyd
ebuild sonykeyd-$version.ebuild digest
ebuild sonykeyd-$version.ebuild manifest

and emerge it:

emerge app-laptop/sonykeyd

to add it to the default run-level do

rc-update add sonypi default
/etc/init.d/sonypi start

The script run when an event occurs is /usr/local/sbin/sonykey.sh, in this version it enables audio (with alsa) and brightness control (you need smartdimmer, read section 8. This is far from perfect, and will be probably updated with your help. :)

If you want to use the events that occurs by pressing the fn key (i.e. fn+F1) in X you need to translate the event to the X event interface. That can be done in several ways, one of them is using evrouter. But I found easier to edit sonykeyd and add an XTestFakeKeyEvent routine.

If you want some kind of on-screen-display you can emerge xosd (use the ~x86 version, the stable one is too old) and edit your sonykey.sh. I use this commands (put them in the relevant section of sonykey.sh)

CATCOM="osd_cat -f -*-aquafont-*-*-*-*-17-*-*-*-*-*-*-uni -c red -s 1 -d 1 -o 30 -i 150 -p bottom"

${CATCOM} -b percentage -P $(amixer sset 'Front' 5- | awk '{if(match($5,/[0-9]+%/)){ print substr($5,RSTART,RLENGTH-1)}}') -T Volume 
${CATCOM} -b percentage -P $(amixer sset 'Front' 5+ | awk '{if(match($5,/[0-9]+%/)){ print substr($5,RSTART,RLENGTH-1)}}') -T Volume 

${CATCOM} -b slider -P $(smartdimmer -g | awk '{print $3*100/21}') -T Brightness

echo mute | ${CATCOM}

Another way of employing the Fn-keys is kvaio-hack HARDWARE_Sony_VGN_S580/kvaio.cpp_hack. It makes use of kmilo and works on my kde-3.5.2.

[edit] Firewire

Firewire works. On your kernel, add the following (M = module. Y = built in)

Device Drivers --> IEEE 1394 (FireWire) support (Y)
 Device Drivers --> IEEE 1394 (FireWire) support --> OHCI-1394 support (M)
 Device Drivers --> IEEE 1394 (FireWire) support --> SBP-2 support (Y)

This will allow for firewire to work, especially with external DVDs and Hard disks. Just recompile your kernel and reboot.

[edit] Miscellaneous

• EEPROM: there's an eeprom available at 0x57. Load i2c_i801 and i2c-dev. Than try decode-vaio.pl. It is possible also to decode the BIOS password.

• Bluetooth: To use a headset, you need to set the SCO mapping to HCI from the default PCM. To do this (may brick your hardware) execute bccmd psset -s default 0x1ab 0. "bccmd" is available from the bluez-utils package. A2DP works too.

[edit] Untested

• Modem (should work with hcfpcimodem)

• MemoryStick: Specs for the chipset are at the TI page. There is talk of a driver at Everest Inc, but no mention of it at TI.com. A similar chipset (according to the firm working on it) is described at this page and a project called tifm21 is linked. Reading through the mailing list archives reveals a binary only driver which is hosted here. I (J.Jordens) have not used it yet for a lack of a proper kernel (gcc 3.3 PREEMPT) and memory stick. Feedback would be appreciated! Another project tifmxx, a "fork" of tifm21.

• TPM chip: supported with the latest kernels, applications include secure booting (GRUB patch), trusted kernel/modules, secure storage and use of ssh/gpg keychains - a smartcard on the motherboard.
