OK. It looks like we have cardbus working on most laptops. I'm currently coming in via the 3C575BT card. At BSDcon we found that the following cards worked: 3C575[CB][CT] Xircom cards (and clones: IBM and Intel) 3c656 (no modem) Dlink generic card There are no modems working right now. Most of them are win modems, but there are some drivers out there for them of unknown quality that haven't been ported to FreeBSD. Some laptops don't work. There are resource allocation issues that need to be addressed. The Dell 5000e is one of the bad ones, iirc. I may need to go buy one of those bad boys. We don't have a list of working/broken laptops at this time. 16-bit cards don't work yet. I've not had time to debug this completely yet. I've cleaned it up, but still need to dig deeper. scsi cards don't work yet. I talked to Justin about this. He has access to code that brings the chips out of power saving mode so that the SBCs are available. Generally speaking, to port to cardbus, you need to add 1 line to most pci drivers since our card bus code emulates a pci bus very well. Many drivers need to be taught to cope with detaching properly as well. In addition, many drivers will need to have some chip specific tweaking due to errata that apply only to cardbus silicon or the manner that the cardbus implementation differs slightly from other cards supported by the driver. A big thanks to Jonathan Chen for his excellent work. The code is mostly stable, but there are still issues. It should be considered advanced alpha or early beta until we get more experience with this code and fix the issues that invariably come up when laptop hardware gets into the loop. It will not be available in -stable for some time, if ever. My palns are to get the 16-bit code working, firm up the issues between now and then and then throw the switch over from OLDCARD to NEWCARD by default. We need an devd infrastructure in place as well. No clue how long all this will take :-) Warner To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
