PAO people thinking PCIC problem below: #Thanks nomads-ML people translate this message. - PCIC is an ISA device. PCIC handles bus, yet the bus is not the bus PCIC belongs to. Please note that a PCIC is an ISA device and a bridge between ISA bus and PC Card bus. Also, if you see codes on NetBSD, bus dependent code and handling bridge is different. - sysctl is the last way to go. It can't work unless the module is loaded after boot. There are also other problems loading the driver with current KLD. - User configuration method dependent on KLD or boot loader is wrong solution. It should be independent from them. - It is clearly wrong to specify the management irq by sysctl. - It is clear that you should consider multiple PCICs. Machines with more than one PCIC are not singular. Any code that does not take the fact into account is apparently wrong. - It is a bad way to handle resources by hard coding. A way for the user to change the resources is must. UserConfig is the available solution, now. - The method used by PAO is the right way to go, although native probe/attach codes for PCI PCIC and CardBus controllers is yet to be written. -- NAKAGAWA, Yoshihisa y-nakaga@nwsl.mesh.ad.jp nakagawa@jp.FreeBSD.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
