  31       <div class="body">
  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
  41 packages.</p>
  42
  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
  46 modalias.</p>
  47
  48 <p><blockquote>
  49 Package: package-name
  50 <br>Modaliases: module(modaliasglob, modaliasglob, modaliasglob)</p>
  51 </blockquote></p>
  52
  53 <p>It is fairly trivial to write code to find the relevant packages
  54 for a given modalias value using this file.</p>
  55
  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>
  58
  59 <p><blockquote>
  60 Package: cheese
  61 <br>Modaliases: cheese(usb:v*p*d*dc*dsc*dp*ic0Eisc01ip*)</p>
  62 </blockquote></p>
  63
  64 <p>An entry like this would suggest the pcmciautils package when a
  65 CardBus bridge (bus class 0607) PCI device is present:</p>
  66
  67 <p><blockquote>
  68 Package: pcmciautils
  69 <br>Modaliases: pcmciautils(pci:v*d*sv*sd*bc06sc07i*)
  70 </blockquote></p>
  71
  72 <p>An entry like this would suggest the package colorhug-client when
  73 plugging in a ColorHug with USB IDs 04D8:F8DA:</p>
  74
  75 <p><blockquote>
  76 Package: colorhug-client
  77 <br>Modaliases: colorhug-client(usb:v04D8pF8DAd*)</p>
  78 </blockquote></p>
  79
  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>
  83
  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
  91 Raring.</p>
  92
  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
  97 try the
  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>
 102
 103 <p>When I use it on a machine with a yubikey inserted, it suggest to
 104 install yubikey-personalization:</p>
 105
 106 <p><blockquote>
 107 % ./hw-support-lookup
 108 <br>yubikey-personalization
 109 <br>%
 110 </blockquote></p>
 111
 112 <p>When I run it on my Thinkpad X40 with a PCMCIA/CardBus slot, it
 113 propose to install the pcmciautils package:</p>
 114
 115 <p><blockquote>
 116 % ./hw-support-lookup
 117 <br>pcmciautils
 118 <br>%
 119 </blockquote></p>
 120
 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>
 124
 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
 132 see if it work.</p>
 133
 134 <p>If you want to help implementing a system to let us propose what
 135 packages to install when new hardware is plugged into a Debian
 136 machine, please send me an email or talk to me on
 137 <a href="irc://irc.debian.org/%23debian-devel">#debian-devel</a>.</p>

 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
 162 in
 163 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/">the
 164 Debian Edu subversion repository</a>:
 165
 166 <p><strong>Modalias decoded</strong></p>
 167
 168 <p>This document try to explain what the different types of modalias
 169 values stands for.  It is in part based on information from
 170 &lt;URL: <a href="https://wiki.archlinux.org/index.php/Modalias">https://wiki.archlinux.org/index.php/Modalias</a> &gt;,
 171 &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;,
 172 &lt;URL: <a href="http://code.metager.de/source/history/linux/stable/scripts/mod/file2alias.c">http://code.metager.de/source/history/linux/stable/scripts/mod/file2alias.c</a> &gt; and
 173 &lt;URL: <a href="http://cvs.savannah.gnu.org/viewvc/dmidecode/dmidecode.c?root=dmidecode&view=markup">http://cvs.savannah.gnu.org/viewvc/dmidecode/dmidecode.c?root=dmidecode&view=markup</a> &gt;.
 174
 175 <p>The modalias entries for a given Linux machine can be found using
 176 this shell script:</p>
 177
 178 <pre>
 179 find /sys -name modalias -print0 | xargs -0 cat | sort -u
 180 </pre>
 181
 182 <p>The supported modalias globs for a given kernel module can be found
 183 using modinfo:</p>
 184
 185 <pre>
 186 % /sbin/modinfo psmouse | grep alias:
 187 alias:          serio:ty05pr*id*ex*
 188 alias:          serio:ty01pr*id*ex*
 189 %
 190 </pre>
 191
 192 <p><strong>PCI subtype</strong></p>
 193
 194 <p>A typical PCI entry can look like this.  This is an Intel Host
 195 Bridge memory controller:</p>
 196
 197 <p><blockquote>
 198 pci:v00008086d00002770sv00001028sd000001ADbc06sc00i00
 199 </blockquote></p>
 200
 201 <p>This represent these values:</p>
 202
 203 <pre>
 204  v   00008086  (vendor)
 205  d   00002770  (device)
 206  sv  00001028  (subvendor)
 207  sd  000001AD  (subdevice)
 208  bc  06        (bus class)
 209  sc  00        (bus subclass)
 210  i   00        (interface)
 211 </pre>
 212
 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>
 217
 218 <p>Not sure how to figure out the interface value, nor what it
 219 means.</p>
 220
 221 <p><strong>USB subtype</strong></p>
 222
 223 <p>Some typical USB entries can look like this.  This is an internal
 224 USB hub in a laptop:</p>
 225
 226 <p><blockquote>
 227 usb:v1D6Bp0001d0206dc09dsc00dp00ic09isc00ip00
 228 </blockquote></p>
 229
 230 <p>Here is the values included in this alias:</p>
 231
 232 <pre>
 233  v    1D6B  (device vendor)
 234  p    0001  (device product)
 235  d    0206  (bcddevice)
 236  dc     09  (device class)
 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)
 242 </pre>
 243
 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>
 247
 248 <p><blockquote>
 249 usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc01ip00
 250 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc02ip00
 251 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc01ip00
 252 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc02ip00
 253 </blockquote></p>
 254
 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>
 258
 259 <p><strong>ACPI subtype</strong></p>
 260
 261 <p>The ACPI type is used for several non-PCI/USB stuff.  This is an IR
 262 receiver in a Thinkpad X40:</p>
 263
 264 <p><blockquote>
 265 acpi:IBM0071:PNP0511:
 266 </blockquote></p>
 267
 268 <p>The values between the colons are IDs.</p>
 269
 270 <p><strong>DMI subtype</strong></p>
 271
 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:</p>
 275
 276 <p><blockquote>
 277 dmi:bvnIBM:bvr1UETB6WW(1.66):bd06/15/2005:svnIBM:pn2371H4G:pvrThinkPadX40:rvnIBM:rn2371H4G:rvrNotAvailable:cvnIBM:ct10:cvrNotAvailable:
 278 </blockquote></p>
 279
 280 <p>The values present are</p>
 281
 282 <pre>
 283  bvn  IBM            (BIOS vendor)
 284  bvr  1UETB6WW(1.66) (BIOS version)
 285  bd   06/15/2005     (BIOS date)
 286  svn  IBM            (system vendor)
 287  pn   2371H4G        (product name)
 288  pvr  ThinkPadX40    (product version)
 289  rvn  IBM            (board vendor)
 290  rn   2371H4G        (board name)
 291  rvr  NotAvailable   (board version)
 292  cvn  IBM            (chassis vendor)
 293  ct   10             (chassis type)
 294  cvr  NotAvailable   (chassis version)
 295 </pre>
 296
 297 <p>The chassis type 10 is Notebook.  Other interesting values can be
 298 found in the dmidecode source:</p>
 299
 300 <pre>
 301   3 Desktop
 302   4 Low Profile Desktop
 303   5 Pizza Box
 304   6 Mini Tower
 305   7 Tower
 306   8 Portable
 307   9 Laptop
 308  10 Notebook
 309  11 Hand Held
 310  12 Docking Station
 311  13 All In One
 312  14 Sub Notebook
 313  15 Space-saving
 314  16 Lunch Box
 315  17 Main Server Chassis
 316  18 Expansion Chassis
 317  19 Sub Chassis
 318  20 Bus Expansion Chassis
 319  21 Peripheral Chassis
 320  22 RAID Chassis
 321  23 Rack Mount Chassis
 322  24 Sealed-case PC
 323  25 Multi-system
 324  26 CompactPCI
 325  27 AdvancedTCA
 326  28 Blade
 327  29 Blade Enclosing
 328 </pre>
 329
 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>
 333
 334 <p><strong>SerIO subtype</strong></p>
 335
 336 <p>This type is used for PS/2 mouse plugs.  One example is from my
 337 test machine:</p>
 338
 339 <p><blockquote>
 340 serio:ty01pr00id00ex00
 341 </blockquote></p>
 342
 343 <p>The values present are</p>
 344
 345 <pre>
 346   ty  01  (type)
 347   pr  00  (prototype)
 348   id  00  (id)
 349   ex  00  (extra)
 350 </pre>
 351
 352 <p>This type is supported by the psmouse driver.  I am not sure what
 353 the valid values are.</p>
 354
 355 <p><strong>Other subtypes</strong></p>
 356
 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>
 364
 365 <p><strong>Looking up kernel modules using modalias values</strong></p>
 366
 367 <p>To check which kernel modules provide support for a given modalias,
 368 one can use the following shell script:</p>
 369
 370 <pre>
 371   for id in $(find /sys -name modalias -print0 | xargs -0 cat | sort -u); do \
 372     echo "$id" ; \
 373     /sbin/modprobe --show-depends "$id"|sed 's/^/  /' ; \
 374   done
 375 </pre>
 376
 377 <p>The output can look like this (only the first few entries as the
 378 list is very long on my test machine):</p>
 379
 380 <pre>
 381   acpi:ACPI0003:

 424       <div class="body">
 425         <p>As part of my investigation on how to improve the support in Debian
 426 for hardware dongles, I dug up my old Mark and Spencer USB Rocket
 427 Launcher and updated the Debian package
 428 <a href="http://packages.qa.debian.org/pymissile">pymissile</a> to make
 429 sure udev will fix the device permissions when it is plugged in.  I
 430 also added a "Modaliases" header to test it in the Debian archive and
 431 hopefully make the package be proposed by jockey in Ubuntu when a user
 432 plug in his rocket launcher.  In the process I moved the source to a
 433 git repository under collab-maint, to make it easier for any DD to
 434 contribute.  <a href="http://code.google.com/p/pymissile/">Upstream</a>
 435 is not very active, but the software still work for me even after five
 436 years of relative silence.  The new git repository is not listed in
 437 the uploaded package yet, because I want to test the other changes a
 438 bit more before I upload the new version.  If you want to check out
 439 the new version with a .desktop file included, visit the
 440 <a href="http://anonscm.debian.org/gitweb/?p=collab-maint/pymissile.git">gitweb
 441 view</a> or use "<tt>git clone

 463         <p>One thing that annoys me with Debian and Linux distributions in
 464 general, is that there is a great package management system with the
 465 ability to automatically install software packages by downloading them
 466 from the distribution mirrors, but no way to get it to automatically
 467 install the packages I need to use the hardware I plug into my
 468 machine.  Even if the package to use it is easily available from the
 469 Linux distribution.  When I plug in a LEGO Mindstorms NXT, it could
 470 suggest to automatically install the python-nxt, nbc and t2n packages
 471 I need to talk to it.  When I plug in a Yubikey, it could propose the
 472 yubikey-personalization package.  The information required to do this
 473 is available, but no-one have pulled all the pieces together.</p>
 474
 475 <p>Some years ago, I proposed to
 476 <a href="http://lists.debian.org/debian-devel/2010/05/msg01206.html">use
 477 the discover subsystem to implement this</a>.  The idea is fairly
 478 simple:
 479
 480 <ul>
 481
 482 <li>Add a desktop entry in /usr/share/autostart/ pointing to a program
 483   starting when a user log in.</li>
 484
 485 <li>Set this program up to listen for kernel events emitted when new
 486   hardware is inserted into the computer.</li>
 487
 488 <li>When new hardware is inserted, look up the hardware ID in a
 489   database mapping to packages, and take note of any non-installed
 490   packages.</li>
 491
 492 <li>Show a message to the user proposing to install the discovered
 493   package, and make it easy to install it.</li>
 494
 495 </ul>
 496
 497 <p>I am not sure what the best way to implement this is, but my
 498 initial idea was to use dbus events to discover new hardware, the
 499 discover database to find packages and
 500 <a href="http://www.packagekit.org/">PackageKit</a> to install
 501 packages.</p>
 502
 503 <p>Yesterday, I found time to try to implement this idea, and the
 504 draft package is now checked into
 505 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/">the
 506 Debian Edu subversion repository</a>.  In the process, I updated the
 507 <a href="http://packages.qa.debian.org/d/discover-data.html">discover-data</a>
 508 package to map the USB ids of LEGO Mindstorms and Yubikey devices to
 509 the relevant packages in Debian, and uploaded a new version
 510 2.2013.01.09 to unstable.  I also discovered that the current
 511 <a href="http://packages.qa.debian.org/d/discover.html">discover</a>
 512 package in Debian no longer discovered any USB devices, because
 513 /proc/bus/usb/devices is no longer present.  I ported it to use
 514 libusb as a fall back option to get it working.  The fixed package
 515 version 2.1.2-6 is now in experimental (didn't upload it to unstable
 516 because of the freeze).</p>
 517
 518 <p>With this prototype in place, I can insert my Yubikey, and get this
 519 desktop notification to show up (only once, the first time it is
 520 inserted):</p>
 521
 522 <p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2013-01-09-hw-autoinstall.png"></p>
 523
 524 <p>For this prototype to be really useful, some way to automatically
 525 install the proposed packages by pressing the "Please install
 526 program(s)" button should to be implemented.</p>
 527
 528 <p>If this idea seem useful to you, and you want to help make it
 529 happen, please help me update the discover-data database with mappings
 530 from hardware to Debian packages.  Check if 'discover-pkginstall -l'
 531 list the package you would like to have installed when a given
 532 hardware device is inserted into your computer, and report bugs using
 533 reportbug if it isn't.  Or, if you know of a better way to provide
 534 such mapping, please let me know.</p>
 535
 536 <p>This prototype need more work, and there are several questions that
 537 should be considered before it is ready for production use.  Is dbus
 538 the correct way to detect new hardware?  At the moment I look for HAL
 539 dbus events on the system bus, because that is the events I could see
 540 on my Debian Squeeze KDE desktop.  Are there better events to use?
 541 How should the user be notified?  Is the desktop notification
 542 mechanism the best option, or should the background daemon raise a
 543 popup instead?  How should packages be installed?  When should they
 544 not be installed?</p>
 545
 546 <p>If you want to help getting such feature implemented in Debian,
 547 please send me an email. :)</p>

 568         <p>During Christmas, I have worked a bit on the Debian support for
 569 <a href="http://mindstorms.lego.com/en-us/Default.aspx">LEGO Mindstorm
 570 NXT</a>.  My son and I have played a bit with my NXT set, and I
 571 discovered I had to build all the tools myself because none were
 572 already in Debian Squeeze.  If Debian support for LEGO is something
 573 you care about, please join me on the IRC channel
 574 <a href="irc://irc.debian.org/%23debian-lego">#debian-lego</a> (server
 575 irc.debian.org).  There is a lot that could be done to improve the
 576 Debian support for LEGO designers.  For example both CAD software
 577 and Mindstorm compilers are missing. :)</p>
