Toshiba - Documentation for Linux Developers

Toshiba - Documentation for Linux Developers

[Renato S. Yamane]

Hi for all,

Toshiba have a 'link' between Linux Developers and Head Company, that is:
<http://linux.toshiba-dme.co.jp/linux/eng/develop.htm>

If someone need documentation to develop Linux drivers, contact
linux@toshiba-dme.co.jp

I'm not a developer, so this is all that I can do.

Best regards,
Renato S. Yamane

Are there any known drivers for Toshiba hardware that you need for Linux
that we should be contacting them about?

thanks,

Greg, in my Toshiba M45-S355, multimedia keys (play, pause, stop, etc)
and Fn+Fx keys don't work.

With no Fn keys, I can't change brightness of monitor (Fn+F6/F7) and
change output video from LCD to VGA (Fn+F5).

I try use "xev" to capture key press, but Fn and Multimedia Keys is not
recognized.

And other problem is with battery charge, as we can see here:
<http://bugzilla.kernel.org/show_bug.cgi?id=10797>

I'm glad to see Toshiba hosting a Linux page, even if it seems
to be missing most of its links at this time, it is a step
in the right direction.

Toshiba specific support in upstream Linux is very weak.
There are two toshiba specific drivers, and ACPI based one,
and an SMM based one.  As far as I can tell, neither has
had any benefit of any support or documentation from Toshiba.
Neither has seen any significant development over the last 3 years.

TOSHIBA ACPI EXTRAS DRIVER
P:      John Belmonte
M:      toshiba_acpi@memebeam.org
W:      http://memebeam.org/toys/ToshibaAcpiDriver
S:      Maintained

TOSHIBA SMM DRIVER
P:      Jonathan Buzzard
M:      jonathan@buzzard.org.uk
L:      tlinux-users@tce.toshiba-dme.co.jp
W:      http://www.buzzard.org.uk/toshiba/
S:      Maintained

More public documentation is a great first step.
But Toshiba could make a huge improvement in Linux support by hiring
just a couple of programmers to help develop and support platform specific
drivers for Toshiba systems in upstream Linux.

Some of the Toshibas use an entirely different method for handling 
hotkeys - I don't think anyone's worked it out yet. Different OEMs, I 
guess.

Sorry: I forgot to mention that you have to turn off the acpi daemon.

If I stop acpid, when I run "cat /proc/acpi/event" nothing happens (when
I press Fn+Fx couple keys or multimedia keys) and I can't get out of cat
command (if I use VIM, I can't close it too).

Re: Toshiba - Documentation for Linux Developers

Hi,

yes, there are some things missing (Bluetooth, ...) . Posted some weeks ago 
in driver-devel list, but no response :-(

http://driverdev.linuxdriverproject.org/pipermail/devel/2008-April/000413.html

cu romal

www.romal.de
blog.romal.de

--------------------

Hi,

the builtin Toshiba Bluetooth adapter is in disabled state by default. It
works perfectly well if enabled.

There are two families of Toshiba notebooks, the ones made by Compal
(PhoenixBIOS), and the original Toshiba manufactured.

The Compal-OEMs are supported by the Omnibook kernel module (along with
some others laptops by HP, ...): http://omnibook.sourceforge.net/doku.php

The Toshiba made notebooks need toshiba_acpi. toshiba_acpi is included in
the kernel but is outdated and does not work on newer models and x86_64. 
The newer one works partially an can be downloaded:
http://memebeam.org/toys/ExperimentalToshibaAcpiDriver

Documentation from Toshiba is available from
http://linux.toshiba-dme.co.jp/linux/eng/develop.htm

Both drivers are maintained outside the kernel.

http://bugzilla.kernel.org/show_bug.cgi?id=10173

Any chance they might be included ?

As my last coding is several years old, I would not be of great help. But I
could assist in docs or testing. Our company does buy Toshiba laptops, so I
have access to various models for testing.

I have Toshiba A100 with Phoenix BIOS. This means toshiba_acpi doesn't
work for me and I can change LCD brightness.

On page http://www.buzzard.me.uk/toshiba/docs.html there is also link
to pdf with registers info:
http://www.buzzard.me.uk/toshiba/downloads/hci.pdf

However I am not programmer and I have no idea if this is some
interesging info for developrs.

Rafal, try use omnibook driver.
Get it with subversion:
$ svn co
https://omnibook.svn.sourceforge.net/svnroot/omnibook/omnibook/trunk

Use "make install" and "make load".

After this, maybe is possible change brightness writing in
/proc/omnibook/lcd (0 is minimun and 7 is max brightness)

The newest version is packed for openSUSE fortunately. But it doesn't
for my notebook. dmesg is:

omnibook: Driver version 2.20070211-trunk.
omnibook: Unknown model.
omnibook: dmi feature has no backend table, io_op not initialized.
omnibook: version feature has no backend table, io_op not initialized.
omnibook: Enabled features: dmi version.

So everything I can do is
toshiba:/proc/omnibook # cat dmi
BIOS Vendor:   Phoenix Technologies LTD
BIOS Version:  2.00
BIOS Release:  08/30/2006
System Vendor: TOSHIBA
Product Name:  SATELLITE A100
Version:       PSAA9E-0R101VPL
Serial Number: X6623092G
Board Vendor:  Intel Corporation
Board Name:    Not Applicable

Try compile SVN version as commented in my last e-mail

> dmesg is:

> omnibook: Unknown model.

Try force recognize with ectype parameter.
#modprobe omnibook ectype=x

Where "x" is a number between 1 and 15.

Load with ectype=1, test, unload, try load again with ectype=2, test,
unload...

Renato

OK, I tried version from SVN. Nothing changed :|

Sure, I tried every ectype between 1 and 15 before (omnibook from
package) and now (version from SVN) again. I checked two files (when
existed): lcd and temperature. Temperature (if file existed for forced
ectype) was always 0 and lcd always had some random values. Inserting
other values (1, 7) didn't change anything.

Re: Toshiba - Documentation for Linux Developers

Hi,

both Toshiba types (original and compal-oem machines) are basically 
unsupported for Linux.

The omnibook-module for compal-systems was maintained outside the kernel 
and stalled for some time now.

The toshiba_acpi included in the kernel is outdated (there is a newer 
release, that fixes some bugs). Toshiba_acpi does only work on 32 bit 
systems, it breaks on 64 bit systems.

If anyone is interested in some hacking I can provide shell-access to 
both types of machines.

For some Tecra machines, Toshiba has provided some Vista-compatible 
BIOSes, they seem to enhance acpi-stuff for Linux too. So you might look 
for a bios-update.
