Adds support for PowerQuicc on-chip PCMCIA. The driver is implemented as of_device, so only arch/powerpc stuff is capable to use it, which now implies only mpc885ads reference board. To cope with the code that should be hooked inside driver, but is really board specific (like set_voltage), global structure mpc8xx_pcmcia_ops holds necessary function pointers that are filled in the BSP code.

Use the eieio function so we can redefine what eieio does rather than direct inline asm. This is part code clean up and partially because not all PPCs have eieio (book-e has mbar that maps to eieio). Signed-off-by: -

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.

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:

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:

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:
