Somebody tried copying the EISA attachment code too closely: there's only one I/O space that needs to be allocated (the pci_io allocation is bogus). The IRQ allocation needs the RF_SHAREABLE flag or it will blow up in the case where the IRQ is shared with another device. Also, the vx driver still uses the ugly hack of statically allocated softc structs. I was working on this in the office the other day and just got done testing it. I have patches to fix all of this, plus make it use the bus_space_*() stuff instead of inb/outb/etc, plus allow it to be compiled as a KLD. The only thing I didn't do was implement detach routines, which means the driver can be loaded as a KLD, but not unloaded. The driver should also build in the alpha. I'll commit the changes to -current shortly. -Bill To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
