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.

+ +

When complete, a user will be able to run a minimal kernel + (currently checked in as the MINIMAL config). Devices + necessary for booting will be loaded by loader(8). 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.

+ + + + +

Go through all the simplebus drivers and add + plug-and-play information there. Some additional minor simplebus + functionality is needed. There is some work in progress for + this.

+ + + +

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.

+ + + +

Run-time parsing and loading is still needed.
