* [POWERPC] Add hugepagesz boot-time parameterJon Tollefson2008-01-172-34/+96
| | | | | | | | | | | | This adds the hugepagesz boot-time parameter for ppc64. It lets one pick the size for huge pages. The choices available are 64K and 16M when the base page size is 4k. It defaults to 16M (previously the only only choice) if nothing or an invalid choice is specified. Tested 64K huge pages successfully with the libhugetlbfs 1.2.

* [POWERPC] iSeries: eliminate pci_dn bussubnoStephen Rothwell2008-01-172-10/+7
| | | | | | | | | | | | | xlate_iomm_address() really wants the ds_addr to pass to the HV, so store that value (instead of the BAR number) when we allocate the device bars. This is not a fast path, so we can look up the device_node property there instead of using the bussubno field of the pci_dn. The other user of iseries_ds_addr() was already scanning the device tree, so looking up a property will not slow it down any more.

* [POWERPC] Add of_find_matching_node() helper functionGrant Likely2008-01-174-0/+4
| | | | | | | | | | | | | | Similar to of_find_compatible_node(), of_find_matching_node() and for_each_matching_node() allow you to iterate over the device tree looking for specific nodes, except that they take of_device_id tables instead of strings. This also moves of_match_node() from driver/of/device.c to driver/of/base.c to colocate it with the of_find_matching_node which depends on it.

* | [POWERPC] 4xx: PCIe: Increase max busses per port to 64Stefan Roese2008-01-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | Because of how big mapping the config space is (1M per bus), we limit how many busses we support for now. In the long run, we could replace that with something akin to kmap_atomic instead. This patch changes the limit from currently 16 to 64.

| * [POWERPC] pasemi: Distribute interrupts evenly across cpusOlof Johansson2007-12-282-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default the OpenPIC on PWRficient will bias to one core (since that will improve changes of the other core being able to stay idle/powered down). However, this conflicts with most irq load balancing schemes, since setting an interrupt to be delivered to either core doesn't really result in the load being shared. It also doesn't work well with the soft irq disable feature of PPC, since EE will stay on until the first interrupt is taken while soft disabled. Set the gconf0 config bit that enables even distribution of interrupts among the two cores. Signed-off-by: Olof Johansson <olof@lixom.net>
| * [POWERPC] pasemi: Implement NMI supportOlof Johansson2007-12-283-9/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some PWRficient-based boards have a NMI button that's wired up to a GPIO as interrupt source. By configuring the openpic accordingly, these get delivered as a machine check with high priority, instead of as an external interrupt. The device tree contains a property "nmi-source" in the openpic node for these systems, and it's the (hwirq) source for the input. Also, for these interrupts, the IACK is read from another register than the regular (MCACK instead), but they are EOI'd as usual. So implement said function for the mpic driver. Finally, move a couple of external function defines to include/ instead of local under sysdev. Being able to mask/unmask and eoi directly saves us from setting up a dummy irq handler that will never be called. Signed-off-by: Olof Johansson <olof@lixom.net>
