[POWERPC] mpc52xx_pic: fix main interrupt masking

2007-04-11T16:39:58Z

The bit setting was off by one. Tested with RTC and GPIO_WKUP interrupts. Signed-off-by: Domen Puncer Signed-off-by: Sylvain Munaut Signed-off-by: Paul Mackerras

[POWERPC] Bypass hcall stats until cpu features have run

2007-03-22T04:01:43Z

I noticed that we execute hcalls before cpu feature code has run (eg for setting up the bolted kernel region). This means that we may be executing code that is not appropriate for the processor we have. Create an unconditional branch that we nop out all the time to fix this.

[POWERPC] Avoid hypervisor statistics calculation in real mode

2007-03-22T04:01:43Z

kexec invokes plpar_hcall hypervisor call in real mode. plpar_hcall refers to per cpu variables for accounting hypervisor statistics. These variables may not be in the RMO region, so accesses to them in real mode may result in a data storage exception. This fixes this problem by using a new plpar_hcall_raw function which does not update the hypervisor call statistics. Thanks to Anton for suggesting this idea.

[POWERPC] ps3: always make sure were running on a PS3

2007-03-09T23:07:51Z

Add missing checks to PS3 specific drivers ps3av and sys-manager to verify that we are actually running on a PS3 (pointed out by Arnd). Correct existing checks in other subsystems/drivers to return -ENODEV instead of zero. Signed-off-by: Geert Uytterhoeven Signed-off-by: Arnd Bergmann

[POWERPC] Fix spu SLB invalidations

2007-03-09T23:07:50Z

The SPU code doesn't properly invalidate SPUs SLBs when necessary, for example when changing a segment size from the hugetlbfs code. In addition, it saves and restores the SLB content on context switches which makes it harder to properly handle those invalidations. This patch removes the saving & restoring for now, something more efficient might be found later on. It also adds a spu_flush_all_slbs(mm) that can be used by the core mm code to flush the SLBs of all SPEs that are running a given mm at the time of the flush. In order to do that, it adds a spinlock to the list of all SPEs and move some bits & pieces from spufs to spu_base.c Signed-off-by: Benjamin Herrenschmidt

[POWERPC] avoid SPU_ACTIVATE_NOWAKE optimization

2007-03-09T23:07:49Z

This optimization was added recently but is still buggy, so back it out for now. Signed-off-by: Arnd Bergmann

[POWERPC] spufs: fix possible memory corruption is spufs_mem_write

2007-03-09T23:07:48Z

Due to a buggy unsigned comparison, it was possible to write beyond the end of the local store file in spufs under some circumstances. This rewrites the buggy function to look more like simple_copy_from_buffer. Signed-off-by: Arnd Bergmann Cc: Ulrich Weigand
