The PHY is active-low on the MPC85xx CDS and the 8560 ADS just had the wrong sense for the internal PCI and CPM interrupts. Signed-off-by:Kumar Gala <galak@kernel.crashing.org>

arch/powerpc still relies on asm-ppc/mmu.h for some 32-bit MMU types. This patch is another step towards fixing this. It takes the portions of asm-ppc/mmu.h related to 8xx embedded CPUs which are still relevant in arch/powerpc and puts them in a new asm-powerpc/mmu-8xx.h, included when appropriate from asm-powerpc/mmu.h.

Make the interrupt numbers match the OpenPIC spec intead of the Freescale docs which distinguish between internal and external interrupts. Now we can use the interrupt number directly to find the register offset associated with it. Signed-off-by: -

For the 83xx, 85xx, and 86xx device trees, add a "local-mac-address" property to every Ethernet node that didn't have one. Add a comment indicating that the "address" and/or "mac-address" properties are deprecated in DTS files and will be removed at a later time. Change all MAC address properties to have a zero MAC address value. Signed-off-by:

The function backing_ops->read_mfc_tagstatus() doesn't return a correct value because the dma_tagstatus_R register isn't saved in CSA. This fixes the problem. Signed-off-by:

When waiting for I/O events on mfc in an SPU context by using poll/epoll syscalls, some of the events can be lost because of wrong order of poll_wait and MFC status checks in the spufs_mfc_poll function and non-atomic update of tagwait. This fixes the problem. Signed-off-by:

spu_activate can be called from multiple threads at the same time on behalf of the same spu context. We need to make sure to only add it once to avoid runqueue corruption. Signed-off-by:

Provide load average information for spu context. The format is identical to /proc/loadavg, which is also where a lot of code and concepts is borrowed from. Signed-off-by:

The new tid file contains the ID of the thread currently running the context, if any. This is used so that the new spu-top and spu-ps tools can find the thread in /proc. Signed-off-by:

spu_deactivate should never be called for nosched contets. Put in a check so we can print a stacktrace and exit early in case it happes erroneously. Signed-off-by:

Add a cpus_allowed allowed filed to struct spu_context so that we always use the cpu mask of the owning thread instead of the one happening to call into the scheduler. Also use this information in grab_runnable_context to avoid spurious wakeups. Signed-off-by:

Update scheduling information on every spu_run to allow for setting threads to realtime priority just before running them. This requires some slightly ugly code in spufs_run_spu because we can just update the information unlocked if the spu is not runnable, but we need to acquire the active_mutex when it is runnable to protect against find_victim. This locking scheme requires opencoding spu_acquire_runnable in spufs_run_spu which actually is a nice cleanup all by itself. Signed-off-by:

The current timeslice code mixes 'jiffies' up with 'spesched ticks'. This change correctly defines the number of time slices each SPE contexts is given, and clarifies the comment. This brings the default timeslice for SPE contexts into a reasonable range. Signed-off-by:
-
Christoph Hellwig authored
Enable preemptive scheduling for non-RT contexts. We use the same algorithms as the CPU scheduler to calculate the time slice length, and for now we also use the same timeslice length as the CPU scheduler. This might be not enough for good performance and can be changed after some benchmarking. Note that currently we do not boost the priority for contexts waiting on the runqueue for a long time, so contexts with a higher nice value could starve ones with less priority. This could easily be fixed once the rework of the spu lists that Luke and I discussed is done. Signed-off-by:

Get rid of the scheduler workqueues that complicated things a lot to a dedicated spu scheduler thread that gets woken by a traditional scheduler tick. By default this scheduler tick runs a HZ * 10, aka one spu scheduler tick for every 10 cpu ticks. Currently the tick is not disabled when we have less context than available spus, but I will implement this later. Signed-off-by:

Use the ppc64 style list management and allocation functions for pci_controllers. This makes the pci_controller structs just a bit more common between ppc32 & ppc64. Signed-off-by: -

In the places we can move to using pci_bus_to_host, this allows us to make pci_bus_to_host static and remove its export. Signed-off-by: -

Make the pci_controller struct use global_number for the PHB domain number instead of index to match what ppc64 does and reuse its pci_domain_nr code. Introduced a pci-common.c to handle shared code between ppc32 & ppc64. Signed-off-by: -
