Thomas Moestl	5fb49f9fd6	Add PCI bus enumeration and latency timer setup to the sparc64 MD PCI ... code. Both tasks are not always performed completely by the firmware. The former is required to get some e450 models to boot; the latter fixes the repeated fifo underruns with hme(4)s and gem(4)s observed on some machines (and probably performance problems with other peripherals as well).	2002-06-12 19:20:57 +00:00
Thomas Moestl	4b5504494d	Add code to print the fault virtual address for uncorrectable DMA errors ... caused by IOMMU misses to aid debugging. This will only work on UltraSPARC-IIi and IIe.	2002-03-23 20:42:23 +00:00
Thomas Moestl	e37d222c43	Merge r1.39 from NetBSD (manage both streaming caches for psycho pairs). ... Use explicit bus space accesses instead of mapping the device memory into kva. Fix support for psycho pairs, and catch up with iommu code changes.	2002-02-13 16:07:59 +00:00
Thomas Moestl	9d69e46260	Add support for the Sun psycho/sabre UPA-PCI bridge, some OpenFirmware ... PCI support code, and a driver for the Sun APB PCI-PCI bridge. Partly ported from NetBSD.	2001-11-09 20:19:58 +00:00
