powerpc/cell: Fix Axon MSI driver dependencies

2009-03-11T06:11:33+00:00

The Axon MSI driver depends on more than just PCI_MSI, so add a
Kconfig fragment for it. Fixes randconfig build failures.

powerpc/cell: add QPACE as a separate Cell platform

2008-12-22T21:19:19+00:00

Since the QPACE (Chromodynamics Parallel Computing on the
Cell Broadband Engine) platform doesn't use a iommu, doesn't
have PCI devices and a MPIC much lesser setup and
configurations are needed. So far all devices are detected
as OF device. A notifier function is used to set the dma_ops
for the of_platform bus. Further this patch splits the
PPC_CELL_NATIVE into PPC_CELL_COMMON which are parts that are
shared with the QPACE platform and the rest.

powerpc/cell: Add support for power button of future IBM cell blades

2008-07-22T00:39:32+00:00

This patch adds support for the power button on future IBM cell blades.
It actually doesn't shut down the machine. Instead it exposes an
input device /dev/input/event0 to userspace which sends KEY_POWER
if power button has been pressed.
haldaemon actually recognizes the button, so a plattform independent acpid
replacement should handle it correctly.

powerpc/cell/cpufreq: Add spu aware cpufreq governor

2008-07-22T00:39:31+00:00

This patch adds a cpufreq governor that takes the number of running spus
into account. It's very similar to the ondemand governor, but not as complex.
Instead of hacking spu load into the ondemand governor it might be easier to
have cpufreq accepting multiple governors per cpu in future.
Don't know if this is the right way, but it would keep the governors simple.

[POWERPC] celleb: Add support for PCI Express

2008-04-24T11:08:14+00:00

This adds support for PCI Express port on Celleb.  I/O space of this
PCI Express port is not mapped in memory space.  So we use the
io-workaround mechanism to make accesses indirect.
