+ <body>
+ <p>Work on automatically loading modules based on the
+ plug-and-play data from devices that are scanned and found to not
+ already have a driver attached is in progress. Digging this
+ information out from kernel modules, as well as tagging relevant
+ bits of driver tables, has been committed. PC Card, USB and some
+ PCI devices now have these markings. This data is stored in a
+ file that the kernel, boot loader and userland processes all have
+ access to.</p>
+
+ <p>When complete, a user will be able to run a minimal kernel
+ (currently checked in as the <tt>MINIMAL</tt> config). Devices
+ necessary for booting will be loaded by <tt>loader(8)</tt>. Other
+ devices may be loaded there, or early in the boot (depending on
+ which gives better performance). Users will still be able to run
+ more "monolithic" configurations, as well as limit which
+ kernel modules are avalibale as can be done today, though without
+ the convenience that automatic loading will provide. This work
+ remains ongoing.</p>

+ <p>Go through all the simplebus drivers and add

+ functionality is needed. There is some work in progress for
+ this.</p>

+
+ <task>
+ <p>Go through all the PCI drivers and add plug-and-play
+ information to them. Unlike PC Card or USB, the PCI bus does
+ not have a stylized table of PCI Ids, so each driver invents
+ its own method, meaning that the semi-mechanical conversion
+ that was done with PC Card and USB will not be possible.
+ Instead, customized code for each dirver will be needed.
+ Since a large number of drivers have their own device tables,
+ the work will be primarily writing a description of the
+ current table style.</p>

+ <p>Run-time parsing and loading is still needed.</p>
