"http://people.skolelinux.org/pere/blog/Using_modalias_info_to_find_packages_handling_my_hardware.html">Using modalias info to find packages handling my hardware
</a>
32 <p>Yesterday, I wrote about the
33 <a href=
"http://people.skolelinux.org/pere/blog/Modalias_strings___a_practical_way_to_map__stuff__to_hardware.html">modalias
34 values provided by the Linux kernel
</a> following my hope for
35 <a href=
"http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html">better
36 dongle support in Debian
</a>. Using this knowledge, I have tested how
37 modalias values attached to package names can be used to map packages
38 to hardware. This allow the system to look up and suggest relevant
39 packages when I plug in some new hardware into my machine, and replace
40 discover and discover-data as the database used to map hardware to
43 <p>I create a modaliases file with entries like the following,
44 containing package name, kernel module name (if relevant, otherwise
45 the package name) and globs matching the relevant hardware
50 <br>Modaliases: module(modaliasglob, modaliasglob, modaliasglob)
</p>
53 <p>It is fairly trivial to write code to find the relevant packages
54 for a given modalias value using this file.
</p>
56 <p>An entry like this would suggest the video and picture application
57 cheese for many USB web cameras (interface bus class
0E01):
</p>
61 <br>Modaliases: cheese(usb:v*p*d*dc*dsc*dp*ic0Eisc01ip*)
</p>
64 <p>An entry like this would suggest the pcmciautils package when a
65 CardBus bridge (bus class
0607) PCI device is present:
</p>
69 <br>Modaliases: pcmciautils(pci:v*d*sv*sd*bc06sc07i*)
72 <p>An entry like this would suggest the package colorhug-client when
73 plugging in a ColorHug with USB IDs
04D8:F8DA:
</p>
76 Package: colorhug-client
77 <br>Modaliases: colorhug-client(usb:v04D8pF8DAd*)
</p>
80 <p>I believe the format is compatible with the format of the Packages
81 file in the Debian archive. Ubuntu already uses their Packages file
82 to store their mappings from packages to hardware.
</p>
84 <p>By adding a XB-Modaliases: header in debian/control, any .deb can
85 announce the hardware it support in a way my prototype understand.
86 This allow those publishing packages in an APT source outside the
87 Debian archive as well as those backporting packages to make sure the
88 hardware mapping are included in the package meta information. I've
89 tested such header in the pymissile package, and its modalias mapping
90 is working as it should with my prototype. It even made it to Ubuntu
93 <p>To test if it was possible to look up supported hardware using only
94 the shell tools available in the Debian installer, I wrote a shell
95 implementation of the lookup code. The idea is to create files for
96 each modalias and let the shell do the matching. Please check out and
98 <a href=
"http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/hw-support-lookup?view=co">hw-support-lookup
</a>
99 shell script. It run without any extra dependencies and fetch the
100 hardware mappings from the Debian archive and the subversion
101 repository where I currently work on my prototype.
</p>
103 <p>When I use it on a machine with a yubikey inserted, it suggest to
104 install yubikey-personalization:
</p>
107 % ./hw-support-lookup
108 <br>yubikey-personalization:
112 <p>When I run it on my Thinkpad X40 with a PCMCIA/CardBus slot, it
113 propose to install the pcmciautils package:
</p>
116 % ./hw-support-lookup
121 <p>If you know of any hardware-package mapping that should be added to
122 <a href=
"http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/modaliases?view=co">my
123 database
</a>, please tell me about it.
</p>
125 <p>It could be possible to generate several of the mappings between
126 packages and hardware. One source would be to look at packages with
127 kernel modules, ie packages with *.ko files in /lib/modules/, and
128 extract their modalias information. Another would be to look at
129 packages with udev rules, ie packages with files in
130 /lib/udev/rules.d/, and extract their vendor/model information to
131 generate a modalias matching rule. I have not tested any of these to

135 packages to install when new hardware is plugged into a Debian
136 machine, please send me an email or talk to me on

158 <p>While looking into how to look up Debian packages based on hardware
159 information, to find the packages that support a given piece of
160 hardware, I refreshed my memory regarding modalias values, and decided
161 to document the details. Here are my findings so far, also available

175 <p>The modalias entries for a given Linux machine can be found using
176 this shell script:
</p>
179 cat $(find /sys -name modalias) | sort -u
182 <p>The supported modalias globs for a given kernel module can be found
186 % /sbin/modinfo psmouse | grep alias:
187 alias: serio:ty05pr*id*ex*
188 alias: serio:ty01pr*id*ex*
192 <p><strong>PCI subtype
</strong></p>
194 <p>A typical PCI entry can look like this. This is an Intel Host
195 Bridge memory controller:
</p>
198 pci:v00008086d00002770sv00001028sd000001ADbc06sc00i00
201 <p>This represent these values:
</p>
206 sv
00001028 (subvendor)
207 sd
000001AD (subdevice)
213 <p>The vendor/device values are the same values outputted from 'lspci
214 -n' as
8086:
2770. The bus class/subclass is also shown by lspci as
215 0600. The
0600 class is a host bridge. Other useful bus values are
216 0300 (VGA compatible card) and
0200 (Ethernet controller).
</p>
218 <p>Not sure how to figure out the interface value, nor what it
221 <p><strong>USB subtype
</strong></p>
223 <p>Some typical USB entries can look like this. This is an internal
224 USB hub in a laptop:
</p>
227 usb:v1D6Bp0001d0206dc09dsc00dp00ic09isc00ip00
230 <p>Here is the values included in this alias:
</p>
233 v
1D6B (device vendor)
234 p
0001 (device product)
237 dsc
00 (device subclass)
238 dp
00 (device protocol)
239 ic
09 (interface class)
240 isc
00 (interface subclass)
241 ip
00 (interface protocol)
244 <p>The
0900 device class/subclass means hub. Some times the relevant
245 class is in the interface class section. For a simple USB web camera,
246 these alias entries show up:
</p>
249 usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc01ip00
250 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc02ip00
251 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc01ip00
252 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc02ip00
255 <p>Interface class
0E01 is video control,
0E02 is video streaming (aka
256 camera),
0101 is audio control device and
0102 is audio streaming (aka
257 microphone). Thus this is a camera with microphone included.
</p>
259 <p><strong>ACPI subtype
</strong></p>
261 <p>The ACPI type is used for several non-PCI/USB stuff. This is an IR
262 receiver in a Thinkpad X40:
</p>
265 acpi:IBM0071:PNP0511:
268 <p>The values between the colons are IDs.
</p>
270 <p><strong>DMI subtype
</strong></p>
272 <p>The DMI table contain lots of information about the computer case
273 and model. This is an entry for a IBM Thinkpad X40, fetched from
274 /sys/devices/virtual/dmi/id/modalias:

291 rvr NotAvailable (board version)
292 cvn IBM (chassis vendor)
294 cvr NotAvailable (chassis version)
297 <p>The chassis type
10 is Notebook. Other interesting values can be
298 found in the dmidecode source:
</p>
302 4 Low Profile Desktop
315 17 Main Server Chassis
318 20 Bus Expansion Chassis
319 21 Peripheral Chassis
321 23 Rack Mount Chassis
330 <p>The chassis type values are not always accurately set in the DMI
331 table. For example my home server is a tower, but the DMI modalias
332 claim it is a desktop.
</p>
334 <p><strong>SerIO subtype
</strong></p>
336 <p>This type is used for PS/
2 mouse plugs. One example is from my
340 serio:ty01pr00id00ex00
343 <p>The values present are
</p>
352 <p>This type is supported by the psmouse driver. I am not sure what
353 the valid values are.
</p>
355 <p><strong>Other subtypes
</strong></p>
357 <p>There are heaps of other modalias subtypes according to
358 file2alias.c. There is the rest of the list from that source: amba,
359 ap, bcma, ccw, css, eisa, hid, i2c, ieee1394, input, ipack, isapnp,
360 mdio, of, parisc, pcmcia, platform, scsi, sdio, spi, ssb, vio, virtio,
361 vmbus, x86cpu and zorro. I did not spend time documenting all of
362 these, as they do not seem relevant for my intended use with mapping
363 hardware to packages when new stuff is inserted during run time.
</p>
365 <p><strong>Looking up kernel modules using modalias values
</strong></p>
367 <p>To check which kernel modules provide support for a given modalias,
368 one can use the following shell script:
</p>
371 for id in $(cat $(find /sys -name modalias)|sort -u); do \
373 /sbin/modprobe --show-depends "$id"|sed 's/^/ /' ; \
377 <p>The output can look like this (only the first few entries as the
378 list is very long on my test machine):

421 <p>As part of my investigation on how to improve the support in Debian
422 for hardware dongles, I dug up my old Mark and Spencer USB Rocket
423 Launcher and updated the Debian package
424 <a href=
"http://packages.qa.debian.org/pymissile">pymissile
</a> to make
425 sure udev will fix the device permissions when it is plugged in. I
426 also added a "Modaliases" header to test it in the Debian archive and
427 hopefully make the package be proposed by jockey in Ubuntu when a user
428 plug in his rocket launcher. In the process I moved the source to a
429 git repository under collab-maint, to make it easier for any DD to
430 contribute.

431 is not very active, but the software still work for me even after five
432 years of relative silence. The new git repository is not listed in
433 the uploaded package yet, because I want to test the other changes a
434 bit more before I upload the new version. If you want to check out
435 the new version with a .desktop file included, visit the

">Lets make hardware dongles easier to use in Debian</a>
459 <p>One thing that annoys me with Debian and Linux distributions in
460 general, is that there is a great package management system with the
461 ability to automatically install software packages by downloading them
462 from the distribution mirrors, but no way to get it to automatically
463 install the packages I need to use the hardware I plug into my
464 machine. Even if the package to use it is easily available from the
465 Linux distribution. When I plug in a LEGO Mindstorms NXT, it could
466 suggest to automatically install the python-nxt, nbc and t2n packages
467 I need to talk to it. When I plug in a Yubikey, it could propose the
468 yubikey-personalization package. The information required to do this
469 is available, but no-one have pulled all the pieces together.</p>
471 <p>Some years ago, I proposed to
472 <a href="http://lists.debian.org/debian-devel/
2010/
05/msg01206.html
">use
473 the discover subsystem to implement this</a>. The idea is fairly
478 <li>Add a desktop entry in /usr/share/autostart/ pointing to a program
479 starting when a user log in.</li>
481 <li>Set this program up to listen for kernel events emitted when new
482 hardware is inserted into the computer.</li>
484 <li>When new hardware is inserted, look up the hardware ID in a
485 database mapping to packages, and take note of any non-installed
488 <li>Show a message to the user proposing to install the discovered
489 package, and make it easy to install it.</li>
493 <p>I am not sure what the best way to implement this is, but my
494 initial idea was to use dbus events to discover new hardware, the
495 discover database to find packages and
496 <a href="http://www.packagekit.org/
">PackageKit</a> to install
499 <p>Yesterday, I found time to try to implement this idea, and the
500 draft package is now checked into
501 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/
">the
502 Debian Edu subversion repository</a>. In the process, I updated the
503 <a href="http://packages.qa.debian.org/d/discover-data.html
">discover-data</a>
504 package to map the USB ids of LEGO Mindstorms and Yubikey devices to
505 the relevant packages in Debian, and uploaded a new version
506 2.2013.01.09 to unstable. I also discovered that the current
507 <a href="http://packages.qa.debian.org/d/discover.html
">discover</a>
508 package in Debian no longer discovered any USB devices, because
509 /proc/bus/usb/devices is no longer present. I ported it to use
510 libusb as a fall back option to get it working. The fixed package
511 version 2.1.2-6 is now in experimental (didn't upload it to unstable
512 because of the freeze).</p>
514 <p>With this prototype in place, I can insert my Yubikey, and get this
515 desktop notification to show up (only once, the first time it is
518 <p align="center
"><img src="http://people.skolelinux.org/pere/blog/images/
2013-
01-
09-hw-autoinstall.png
"></p>
520 <p>For this prototype to be really useful, some way to automatically
521 install the proposed packages by pressing the "Please install
522 program(s)" button should to be implemented.
</p>
524 <p>If this idea seem useful to you, and you want to help make it
525 happen, please help me update the discover-data database with mappings
526 from hardware to Debian packages. Check if 'discover-pkginstall -l'
527 list the package you would like to have installed when a given
528 hardware device is inserted into your computer, and report bugs using
529 reportbug if it isn't. Or, if you know of a better way to provide
530 such mapping, please let me know.
</p>
532 <p>This prototype need more work, and there are several questions that
533 should be considered before it is ready for production use. Is dbus
534 the correct way to detect new hardware? At the moment I look for HAL
535 dbus events on the system bus, because that is the events I could see
536 on my Debian Squeeze KDE desktop. Are there better events to use?
537 How should the user be notified? Is the desktop notification
538 mechanism the best option, or should the background daemon raise a
539 popup instead? How should packages be installed? When should they
540 not be installed?
</p>
542 <p>If you want to help getting such feature implemented in Debian,
543 please send me an email. :)

607 Norge de siste månedene.
</li>
609 <li>BankID er et opplegg der utsteder (dvs. banken eller dens
610 leverandør) sitter på alt som trengs for å bruke BankID, men har
611 lovet å ikke bruke den unntatt på oppdrag fra deg. Det er greit nok
612 for banktjenester, der banken allerede har full kontroll over
613 resultatet, men problematisk når det gjelder tilgang til
614 helseopplysninger og avtaleinngåelse med andre enn banken. Jeg
615 håper protestene brer om seg.
