powerpc: Remove the celleb support

2015-04-07T07:15:13+00:00

The celleb code has seen no actual development for ~7 years. We (maintainers) have no access to test hardware, and it is highly likely the code has bit-rotted. As far as we're aware the hardware was never widely available, and is certainly no longer available, and no one on the list has shown any interest in it over the years. So remove it. If anyone has one and cares please speak up. Signed-off-by: Michael Ellerman Acked-by: Benjamin Herrenschmidt Acked-by: Jeremy Kerr

powerpc/cell: Move spu_handle_mm_fault() out of cell platform

2014-10-08T09:14:54+00:00

Currently spu_handle_mm_fault() is in the cell platform. This code is generically useful for other non-cell co-processors on powerpc. This patch moves this function out of the cell platform into arch/powerpc/mm so that others may use it. Signed-off-by: Ian Munsie Signed-off-by: Michael Neuling Signed-off-by: Michael Ellerman

cpufreq: powerpc/platforms/cell: move cpufreq driver to drivers/cpufreq

2013-04-10T11:19:26+00:00

This patch moves cpufreq driver of powerpc platforms/cell to drivers/cpufreq. Signed-off-by: Viresh Kumar Acked-by: Arnd Bergmann Signed-off-by: Rafael J. Wysocki

powerpc: Remove stubbed beat smp support

2011-05-19T05:30:59+00:00

I have no idea if the beat hypervisor supports multiple cpus in a partition, but the code has not been touched since these stubs were added in February of 2007 except to move them in April of 2008. These are stubs: start_cpu always returns fail (which is dropped), the message passing and reciving are empty functions, and the top of file comment says "Incomplete".

powerpc/pci: Move IO workarounds to the common kernel dir

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. Signed-off-by: Michael Ellerman Signed-off-by: Benjamin Herrenschmidt

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. Signed-off-by: Benjamin Krill Signed-off-by: Arnd Bergmann

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. Signed-off-by: Christian Krafft Signed-off-by: Arnd Bergmann Acked-by: Dave Jones Signed-off-by: Benjamin Herrenschmidt

[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. Signed-off-by: Kou Ishizaki Acked-by: Arnd Bergmann Signed-off-by: Paul Mackerras
