Hi, I've attached a patch with changes I had to make to MI bus-related code for the sparc64 port. I would like to commit soonish (around the 21st) if there are no objections. The changes are in detail: - pass the bus device to isa_init() - add a generic resource list printing function, and make use of it in the PCI and ISA code (this may change the order in which the resources are printed in the ISA case). - add a generic __BUS_ACCESSOR macro to generate ivar accessors like PCI_ACCESSOR did, and make use of it in the PCI code - add a 'PCI_BROKEN_INTPIN' option. It activates a workaround for a bug in some Sun PCI devices, which have the intpin register wired to 0 although they use this interrupt generation mechanism. - another new option, PCI_INTLINE_0_BAD, indicates that an intline register value of 0 is used to indicate an unrouted interrupt. It is required for some Sun boxes in conjunction with PCI_BROKEN_INTPIN to avoid the confusing detection of interrupts that are not actually present. - make most functions in pci_pci.c non-static and add a new header (pcib.h) and an extension pointer to the softc to allow drivers for non-standard PCI-PCI bridges to use this code instead of duplicating most of it. - add a variation of rman_reserve_resource(), rman_reserve_resource_bound(), that can additionally honor a boundary for the allocation. This way, the resource manager can be used to handle DVMA allocations, for example. - fix a few bugs in subr_bus.c and subr_rman.c related to the use of min()/max() when ulmin()/ulmax() should be used. It is tested on sparc64 and i386, and build-tested on alpha. It would be nice if somebody could try to build a kernel with it on ia64 (there is a one-line change to ia64-specific code). The patch is also available at http://people.FreeBSD.org/~tmm/sparc64-bus-mi.diff Comments?
