| − | == ThinkPad T43 2687-DDU setup for Debian Etch == | + | == Who is Hmh? == |
| | | | |
| − | This is an ongoing, spotty guide for an advanced {{Debian}} setup of a {{T43}}, focused on using absolutely all of its capabilities that can be used. It is not an installation guide, but rather a configuration guide. Refer to {{Debian}} for a list of pages with initial installation instructions.
| + | I am a Debian Developer for quite a few years now, and the current maintainer of [[ibm-acpi]]/[[thinkpad-acpi]], aka "ThinkPad ACPI Extras" Linux kernel driver for ThinkPad laptops. |
| | | | |
| − | When it is really usable, I will move it to some other far more public place in [[ThinkWiki]].
| + | I am also involved with the [[tp_smapi]] and [[HDAPS]] Linux drivers, as a beta-tester and power-user. I don't list myself as a developer for those projects because I have never contributed a single line of code to them, just suggestions and bug reports ;-) |
| | | | |
| − | Installing should be done using the latest Debian Etch debian-installer release. Anything else simply will not run on the ThinkPad.
| + | == My ThinkPads == |
| | | | |
| − | === Kernel ===
| + | I own just a simple [[:Category:T43|T43]] model 2687-DDU. It is a great machine: a very solid ThinkPad, with its own set of annoying quirks just like any other IBM-era ThinkPad. The SATA-PATA bridge, tg3 noise at full network load, and lack of support for AHCI being the worst ones IMHO. |
| | | | |
| − | Baseline kernel: Debian's latest 2.6.16 (2.6.16.17 with stabilization patches) {{NOTE|Thinkpad support is an ongoing, bleeding edge effort. One ends up needing to apply a ton of patches and to use the latest available kernel, sometimes even kernels not yet released}} {{HINT|The [http://members.optusnet.com.au/ckolivas/kernel/ Con Kolivas (ck) desktop kernel] patches might be very applicable to a ThinkPad Kernel}}
| + | == ping == |

| − | ==== Patches employed ====
| + | This is a ping edit, to let Akw know I am still alive and to not purge my account ;-) |
| − | * Latest ipw2200 driver and ieee80211 layer:
| |
| − | :There are two ways to go about this: either '''disable''' IEEE 802.11 support (and thus ipw2200) in the kernel and build both modules out-of-tree (failure to do so will break the out-of-tree build), or update the kernel subsystems with more up-to-date files.
| |
| − | :The advantage of updating the kernel drivers instead of doing an out-of-tree build is that should there be any configuration options that require ieee80211 support, those will be available. On the other hand, it is a bit more difficult, as you will have to mess with Kconfig.
| |
| − | :* copied files over the in-kernel files in {{path|include/net}}, {{path|drivers/net/wireless}}, {{path|Documentation/networking}}, {{path|net/ieee80211}}, thus replacing the old drivers with the new ones.
| |
| − | :* ipw2200 often have extra options you need to enable, look in the toplevel Makefile and add them to {{path|drivers/net/wireless/Kconfig}}. They are usually bool types, so it is trivial to copy, e.g. IPW_DEBUG and rename to the new required options.

| − | ==== Simple configuration issues ====
| |
| − | | |
| − | These are fairly simple minor things you might want to do:
| |
| − | | |
| − | ===== /etc/sysctl.conf =====
| |
| − | | |
| − | install the procps package. Add the following lines to /etc/sysctl.conf:
| |
| − | | |
| − | {{FIXME|nothing here yet}}
| |
| − | | |
| − | ===== /etc/sysfs.conf =====
| |
| − | | |
| − | install the sysfsutils package. Add the following lines to /etc/sysfs.conf
| |
| − | | |
| − | # ThinkPad battery charger defaults
| |
| − | devices/platform/smapi/BAT0/start_charge_tresh=40
| |
| − | devices/platform/smapi/BAT0/stop_charge_tresh=85
| |
| − | devices/platform/smapi/BAT1/start_charge_tresh=70
| |
| − | devices/platform/smapi/BAT1/stop_charge_tresh=90
| |
| − |
| |
| − | # Default frequency scalling governor
| |
| − | devices/system/cpu/cpu0/cpufreq/scaling_governor=conservative
| |
| − | | |
| − | ==== udev rules ====
| |
| − | | |
| − | # udev extended network interface naming needs to be configured, order of tg3/ipw2200 won't be respected if {{path|/etc/modules.conf}} is read after udev did the PCI coldplugging
| |
| − | | |
| − | ==== Kernel/module configuration ====
| |
| − | | |
| − | This is done in /etc/modprobe.d/ files. Install the setserial package.
| |
| − | | |
| − | Add a /etc/modprobe.d/thinkpad-t43 file there with this content:
| |
| − | # Intel Wireless, default to radio offline for safety and security
| |
| − | options ipw2200 disable=1 led=1 hwcrypto=1
| |
| − |
| |
| − | # IrDA
| |
| − | alias irda0 nsc-ircc
| |
| − | options nsc-ircc dongle_id=0x09 io=0x2f8 irq=3 dma=3
| |
| − | install nsc-ircc /bin/setserial /dev/ttyS1 uart none port 0 irq 0; /sbin/modprobe --ignore-install nsc-ircc

| − | ==== Software that needs packaging ====
| |
| − | {{NOTE|If nobody beats me to it, I will probably package them for official upload to Debian, and official Debian Sarge backports. This requires that the software be properly licensed first, of course}}
| |
| − | * hdapsd (a bit crude, needs a lot of work still)
| |
| − | * ipw2200/ieee80211 need adopting, and since they clash terribly with in-kernel support, they will only work right if we either convert them to be patch-based, or to detect that the user built with in-kernel ieee80211/ipw2200 enabled and abort the out-of-tree compilation.
| |
| − | | |
| − | ==== Software that could benefit from re-packaging ====
| |
| − | * hsfmodem: should be easy to build out-of-tree in another machine other than the one it will be installed at
