Linus and Alan last year (end Dec 2000), told that it would nice to have some kind of autoconfiguration. The problem was the bug report about non running kernel, because of false configuration (CPU configuration). How many people try new kernel with the wrong CPU configuration? (and mornally user know the name of own CPU, with netcards this is more difficult). [ We don't reduce trafic on lkml, because the fewer bug reports are hidden by this huge flamewar] > > 2.

(so a soft detection, but with some tests, I can say that with this soft detection we can detect nearly all, without the difficult to write hard probes). > > 3.

I will send Eric the new detections and database for new probes (for ISA and others) drivers. So I hope also the ISA thread will end. giacomo ^ permalink raw reply [flat|nested] 6+ messages in thread

All of us get the CPU wrong. By using modules however I don't have to guess the PCI devices. My system already did that. I just need the configurator to hit M a lot and to work out which root devices are for the initrd. The code for that exists > PCI, USB and ISAPNP detection works well. > ISA is a further step. > I will send Eric the new detections and database for new probes (for ISA > and others) drivers. So I hope also the ISA thread will end. I suspect ISA is a dead loss - but again build all the modules, the user system already has the right ones to load configured.

Then get HPA to give you a space on kernel.org for "Giacomo Standard Configure Entries" which you update. _Much_ less pain going around that way. -- Horst von Brand http://counter.li.org # 22616 ^ permalink raw reply [flat|nested] 6+ messages in thread
