[SPARC64]: Restrict PCI bus scanning on SUN4V. · 987b6de7

David S. Miller authored Feb 14, 2006

On the PBM's first bus number, only allow device 0, function 0, to be
poked at with PCI config space accesses.

For some reason, this single device responds to all device numbers.

Also, reduce the verbiage of the debugging log printk's for PCI cfg
space accesses in the SUN4V PCI controller driver, so that it doesn't
overwhelm the slow SUN4V hypervisor console.

there is nothing we can really do but work around
it.

[SPARC64]: Fix IOMMU mapping on sun4v. · 7c8f486a

David S. Miller authored Feb 13, 2006

We should dynamically allocate the per-cpu pglist not use
an in-kernel-image datum, since __pa() does not work on
such addresses.

Also, consistently use "u32" for devhandle.

[SPARC64] sunhv: Bug fixes. · d5a2aa24

David S. Miller authored Feb 13, 2006

Add udelay to polling console write loop, and increment
the loop limit.

Name the device "ttyHV" and pass that to add_preferred_console()
when we're using hypervisor console.

Kill sunhv_console_setup(), it's empty.

Handle the case where we don't want to use hypervisor console.
(ie. we have a head attached to a sun4v machine)

[SPARC64]: More SUN4V PCI work. · 10804828

David S. Miller authored Feb 13, 2006

Get bus range from child of PCI controller root nexus.
This is actually a hack, but the PCI-E bridge sitting
at the top of the PCI tree responds to PCI config cycles
for every device number, so best to just ignore it for now.

Preliminary PCI irq routing, needs lots of work.
