  32         <p>Some times I try to figure out which Iceweasel browser plugin to
  33 install to get support for a given MIME type.  Thanks to
  34 <a href="https://wiki.ubuntu.com/MozillaTeam/Plugins">specifications
  35 done by Ubuntu</a> and Mozilla, it is possible to do this in Debian.
  36 Unfortunately, not very many packages provide the needed meta
  37 information, Anyway, here is a small script to look up all browser
  38 plugin packages announcing ther MIME support using this specification:</p>
  39
  40 <pre>
  41 #!/usr/bin/python
  42 import sys
  43 import apt
  44 def pkgs_handling_mimetype(mimetype):
  45     cache = apt.Cache()
  46     cache.open(None)
  47     thepkgs = []
  48     for pkg in cache:
  49         version = pkg.candidate
  50         if version is None:
  51             version = pkg.installed
  52         if version is None:
  53             continue
  54         record = version.record
  55         if not record.has_key('Npp-MimeType'):
  56             continue
  57         mime_types = record['Npp-MimeType'].split(',')
  58         for t in mime_types:
  59             t = t.rstrip().strip()
  60             if t == mimetype:
  61                 thepkgs.append(pkg.name)
  62     return thepkgs
  63 mimetype = "audio/ogg"
  64 if 1 < len(sys.argv):
  65     mimetype = sys.argv[1]
  66 print "Browser plugin packages supporting %s:" % mimetype
  67 for pkg in pkgs_handling_mimetype(mimetype):
  68     print "  %s" %pkg
  69 </pre>
  70
  71 <p>It can be used like this to look up a given MIME type:</p>
  72
  73 <pre>
  74 % ./apt-find-browserplug-for-mimetype
  75 Browser plugin packages supporting audio/ogg:
  76   gecko-mediaplayer
  77 % ./apt-find-browserplug-for-mimetype application/x-shockwave-flash
  78 Browser plugin packages supporting application/x-shockwave-flash:
  79   browser-plugin-gnash
  80 %
  81 </pre>
  82
  83 <p>In Ubuntu this mechanism is combined with support in the browser
  84 itself to query for plugins and propose to install the needed
  85 packages.  It would be great if Debian supported such feature too.  Is
  86 anyone working on adding it?</p>

 107         <p>The <a href="http://wiki.debian.org/AppStreamDebianProposal">DEP-11
 108 proposal to add AppStream information to the Debian archive</a>, is a
 109 proposal to make it possible for a Desktop application to propose to
 110 the user some package to install to gain support for a given MIME
 111 type, font, library etc. that is currently missing.  With such
 112 mechanism in place, it would be possible for the desktop to
 113 automatically propose and install leocad if some LDraw file is
 114 downloaded by the browser.</p>
 115
 116 <p>To get some idea about the current content of the archive, I decided
 117 to write a simple program to extract all .desktop files from the
 118 Debian archive and look up the claimed MIME support there.  The result
 119 can be found on the
 120 <a href="http://ftp.skolelinux.org/pub/AppStreamTest">Skolelinux FTP
 121 site</a>.  Using the collected information, it become possible to
 122 answer the question in the title.  Here are the 20 most supported MIME
 123 types in Debian stable (Squeeze), testing (Wheezy) and unstable (Sid).
 124 The complete list is available from the link above.</p>

 207 <p>I am told that PackageKit can provide an API to access the kind of
 208 information mentioned in DEP-11.  I have not yet had time to look at
 209 it, but hope the PackageKit people in Debian are on top of these
 210 issues.</p>

 233       <div class="body">
 234         <p>Yesterday, I wrote about the
 235 <a href="http://people.skolelinux.org/pere/blog/Modalias_strings___a_practical_way_to_map__stuff__to_hardware.html">modalias
 236 values provided by the Linux kernel</a> following my hope for
 237 <a href="http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html">better
 238 dongle support in Debian</a>.  Using this knowledge, I have tested how
 239 modalias values attached to package names can be used to map packages
 240 to hardware.  This allow the system to look up and suggest relevant
 241 packages when I plug in some new hardware into my machine, and replace
 242 discover and discover-data as the database used to map hardware to
 243 packages.</p>
 244
 245 <p>I create a modaliases file with entries like the following,
 246 containing package name, kernel module name (if relevant, otherwise
 247 the package name) and globs matching the relevant hardware
 248 modalias.</p>
 249
 250 <p><blockquote>
 251 Package: package-name
 252 <br>Modaliases: module(modaliasglob, modaliasglob, modaliasglob)</p>
 253 </blockquote></p>
 254
 255 <p>It is fairly trivial to write code to find the relevant packages
 256 for a given modalias value using this file.</p>
 257
 258 <p>An entry like this would suggest the video and picture application
 259 cheese for many USB web cameras (interface bus class 0E01):</p>
 260
 261 <p><blockquote>
 262 Package: cheese
 263 <br>Modaliases: cheese(usb:v*p*d*dc*dsc*dp*ic0Eisc01ip*)</p>
 264 </blockquote></p>
 265
 266 <p>An entry like this would suggest the pcmciautils package when a
 267 CardBus bridge (bus class 0607) PCI device is present:</p>
 268
 269 <p><blockquote>
 270 Package: pcmciautils
 271 <br>Modaliases: pcmciautils(pci:v*d*sv*sd*bc06sc07i*)
 272 </blockquote></p>
 273
 274 <p>An entry like this would suggest the package colorhug-client when
 275 plugging in a ColorHug with USB IDs 04D8:F8DA:</p>
 276
 277 <p><blockquote>
 278 Package: colorhug-client
 279 <br>Modaliases: colorhug-client(usb:v04D8pF8DAd*)</p>
 280 </blockquote></p>
 281
 282 <p>I believe the format is compatible with the format of the Packages
 283 file in the Debian archive.  Ubuntu already uses their Packages file
 284 to store their mappings from packages to hardware.</p>
 285
 286 <p>By adding a XB-Modaliases: header in debian/control, any .deb can
 287 announce the hardware it support in a way my prototype understand.
 288 This allow those publishing packages in an APT source outside the
 289 Debian archive as well as those backporting packages to make sure the
 290 hardware mapping are included in the package meta information.  I've
 291 tested such header in the pymissile package, and its modalias mapping
 292 is working as it should with my prototype.  It even made it to Ubuntu
 293 Raring.</p>
 294
 295 <p>To test if it was possible to look up supported hardware using only
 296 the shell tools available in the Debian installer, I wrote a shell
 297 implementation of the lookup code.  The idea is to create files for
 298 each modalias and let the shell do the matching.  Please check out and
 299 try the
 300 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/hw-support-lookup?view=co">hw-support-lookup</a>
 301 shell script.  It run without any extra dependencies and fetch the
 302 hardware mappings from the Debian archive and the subversion
 303 repository where I currently work on my prototype.</p>
 304
 305 <p>When I use it on a machine with a yubikey inserted, it suggest to
 306 install yubikey-personalization:</p>
 307
 308 <p><blockquote>
 309 % ./hw-support-lookup
 310 <br>yubikey-personalization
 311 <br>%
 312 </blockquote></p>
 313
 314 <p>When I run it on my Thinkpad X40 with a PCMCIA/CardBus slot, it
 315 propose to install the pcmciautils package:</p>
 316
 317 <p><blockquote>
 318 % ./hw-support-lookup
 319 <br>pcmciautils
 320 <br>%
 321 </blockquote></p>
 322
 323 <p>If you know of any hardware-package mapping that should be added to
 324 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/modaliases?view=co">my
 325 database</a>, please tell me about it.</p>
 326
 327 <p>It could be possible to generate several of the mappings between
 328 packages and hardware.  One source would be to look at packages with
 329 kernel modules, ie packages with *.ko files in /lib/modules/, and
 330 extract their modalias information.  Another would be to look at
 331 packages with udev rules, ie packages with files in
 332 /lib/udev/rules.d/, and extract their vendor/model information to
 333 generate a modalias matching rule.  I have not tested any of these to
 334 see if it work.</p>
 335
 336 <p>If you want to help implementing a system to let us propose what
 337 packages to install when new hardware is plugged into a Debian
 338 machine, please send me an email or talk to me on
 339 <a href="irc://irc.debian.org/%23debian-devel">#debian-devel</a>.</p>

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

 368 <p><strong>Modalias decoded</strong></p>
 369
 370 <p>This document try to explain what the different types of modalias
 371 values stands for.  It is in part based on information from
 372 &lt;URL: <a href="https://wiki.archlinux.org/index.php/Modalias">https://wiki.archlinux.org/index.php/Modalias</a> &gt;,
 373 &lt;URL: <a href="http://unix.stackexchange.com/questions/26132/how-to-assign-usb-driver-to-device">http://unix.stackexchange.com/questions/26132/how-to-assign-usb-driver-to-device</a> &gt;,

 376
 377 <p>The modalias entries for a given Linux machine can be found using
 378 this shell script:</p>
 379
 380 <pre>
 381 find /sys -name modalias -print0 | xargs -0 cat | sort -u
 382 </pre>
 383
 384 <p>The supported modalias globs for a given kernel module can be found
 385 using modinfo:</p>
 386
 387 <pre>
 388 % /sbin/modinfo psmouse | grep alias:
 389 alias:          serio:ty05pr*id*ex*
 390 alias:          serio:ty01pr*id*ex*
 391 %
 392 </pre>
 393
 394 <p><strong>PCI subtype</strong></p>
 395
 396 <p>A typical PCI entry can look like this.  This is an Intel Host
 397 Bridge memory controller:</p>
 398
 399 <p><blockquote>
 400 pci:v00008086d00002770sv00001028sd000001ADbc06sc00i00
 401 </blockquote></p>
 402
 403 <p>This represent these values:</p>
 404
 405 <pre>
 406  v   00008086  (vendor)
 407  d   00002770  (device)
 408  sv  00001028  (subvendor)
 409  sd  000001AD  (subdevice)
 410  bc  06        (bus class)
 411  sc  00        (bus subclass)
 412  i   00        (interface)
 413 </pre>
 414
 415 <p>The vendor/device values are the same values outputted from 'lspci
 416 -n' as 8086:2770.  The bus class/subclass is also shown by lspci as
 417 0600.  The 0600 class is a host bridge.  Other useful bus values are
 418 0300 (VGA compatible card) and 0200 (Ethernet controller).</p>
 419
 420 <p>Not sure how to figure out the interface value, nor what it
 421 means.</p>
 422
 423 <p><strong>USB subtype</strong></p>
 424
 425 <p>Some typical USB entries can look like this.  This is an internal
 426 USB hub in a laptop:</p>
 427
 428 <p><blockquote>
 429 usb:v1D6Bp0001d0206dc09dsc00dp00ic09isc00ip00
 430 </blockquote></p>
 431
 432 <p>Here is the values included in this alias:</p>
 433
 434 <pre>
 435  v    1D6B  (device vendor)
 436  p    0001  (device product)
 437  d    0206  (bcddevice)
 438  dc     09  (device class)
 439  dsc    00  (device subclass)
 440  dp     00  (device protocol)
 441  ic     09  (interface class)
 442  isc    00  (interface subclass)
 443  ip     00  (interface protocol)
 444 </pre>
 445
 446 <p>The 0900 device class/subclass means hub.  Some times the relevant
 447 class is in the interface class section.  For a simple USB web camera,
 448 these alias entries show up:</p>
 449
 450 <p><blockquote>

 627         <p>As part of my investigation on how to improve the support in Debian
 628 for hardware dongles, I dug up my old Mark and Spencer USB Rocket
 629 Launcher and updated the Debian package
 630 <a href="http://packages.qa.debian.org/pymissile">pymissile</a> to make
 631 sure udev will fix the device permissions when it is plugged in.  I
 632 also added a "Modaliases" header to test it in the Debian archive and
 633 hopefully make the package be proposed by jockey in Ubuntu when a user
 634 plug in his rocket launcher.  In the process I moved the source to a
 635 git repository under collab-maint, to make it easier for any DD to
 636 contribute.  <a href="http://code.google.com/p/pymissile/">Upstream</a>
 637 is not very active, but the software still work for me even after five
 638 years of relative silence.  The new git repository is not listed in
 639 the uploaded package yet, because I want to test the other changes a
 640 bit more before I upload the new version.  If you want to check out
 641 the new version with a .desktop file included, visit the
 642 <a href="http://anonscm.debian.org/gitweb/?p=collab-maint/pymissile.git">gitweb

 665         <p>One thing that annoys me with Debian and Linux distributions in
 666 general, is that there is a great package management system with the
 667 ability to automatically install software packages by downloading them
 668 from the distribution mirrors, but no way to get it to automatically
 669 install the packages I need to use the hardware I plug into my
 670 machine.  Even if the package to use it is easily available from the
 671 Linux distribution.  When I plug in a LEGO Mindstorms NXT, it could
 672 suggest to automatically install the python-nxt, nbc and t2n packages
 673 I need to talk to it.  When I plug in a Yubikey, it could propose the
 674 yubikey-personalization package.  The information required to do this
 675 is available, but no-one have pulled all the pieces together.</p>
 676
 677 <p>Some years ago, I proposed to
 678 <a href="http://lists.debian.org/debian-devel/2010/05/msg01206.html">use
 679 the discover subsystem to implement this</a>.  The idea is fairly
 680 simple:
 681
 682 <ul>
 683
 684 <li>Add a desktop entry in /usr/share/autostart/ pointing to a program
 685   starting when a user log in.</li>
 686
 687 <li>Set this program up to listen for kernel events emitted when new
 688   hardware is inserted into the computer.</li>
 689
 690 <li>When new hardware is inserted, look up the hardware ID in a
 691   database mapping to packages, and take note of any non-installed
 692   packages.</li>
 693
 694 <li>Show a message to the user proposing to install the discovered
 695   package, and make it easy to install it.</li>
 696
 697 </ul>
 698
 699 <p>I am not sure what the best way to implement this is, but my
 700 initial idea was to use dbus events to discover new hardware, the
 701 discover database to find packages and
 702 <a href="http://www.packagekit.org/">PackageKit</a> to install
 703 packages.</p>
 704
 705 <p>Yesterday, I found time to try to implement this idea, and the
 706 draft package is now checked into
 707 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/">the
 708 Debian Edu subversion repository</a>.  In the process, I updated the
 709 <a href="http://packages.qa.debian.org/d/discover-data.html">discover-data</a>
 710 package to map the USB ids of LEGO Mindstorms and Yubikey devices to
 711 the relevant packages in Debian, and uploaded a new version
 712 2.2013.01.09 to unstable.  I also discovered that the current
 713 <a href="http://packages.qa.debian.org/d/discover.html">discover</a>
 714 package in Debian no longer discovered any USB devices, because
 715 /proc/bus/usb/devices is no longer present.  I ported it to use
 716 libusb as a fall back option to get it working.  The fixed package
 717 version 2.1.2-6 is now in experimental (didn't upload it to unstable
 718 because of the freeze).</p>
 719
 720 <p>With this prototype in place, I can insert my Yubikey, and get this
 721 desktop notification to show up (only once, the first time it is
 722 inserted):</p>
 723
 724 <p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2013-01-09-hw-autoinstall.png"></p>
 725
 726 <p>For this prototype to be really useful, some way to automatically
 727 install the proposed packages by pressing the "Please install
 728 program(s)" button should to be implemented.</p>
 729
 730 <p>If this idea seem useful to you, and you want to help make it
 731 happen, please help me update the discover-data database with mappings
 732 from hardware to Debian packages.  Check if 'discover-pkginstall -l'
 733 list the package you would like to have installed when a given
 734 hardware device is inserted into your computer, and report bugs using
 735 reportbug if it isn't.  Or, if you know of a better way to provide
 736 such mapping, please let me know.</p>
 737
 738 <p>This prototype need more work, and there are several questions that
 739 should be considered before it is ready for production use.  Is dbus
 740 the correct way to detect new hardware?  At the moment I look for HAL
 741 dbus events on the system bus, because that is the events I could see
 742 on my Debian Squeeze KDE desktop.  Are there better events to use?
 743 How should the user be notified?  Is the desktop notification
 744 mechanism the best option, or should the background daemon raise a
 745 popup instead?  How should packages be installed?  When should they
 746 not be installed?</p>
 747
 748 <p>If you want to help getting such feature implemented in Debian,
 749 please send me an email. :)</p>
