* [POWERPC] ppc64: support CONFIG_DEBUG_PREEMPTHugh Dickins2007-10-02
| | | | | | | | | | | | | | | | | | | Add CONFIG_DEBUG_PREEMPT support to ppc64: it was useful for testing get_paca() preemption. Cheat a little, just use debug_smp_processor_id() in the debug version of get_paca(): it contains all the right checks and reporting, though get_paca() doesn't really use smp_processor_id(). Use local_paca for what might have been called __raw_get_paca(). Silence harmless warnings from io.h and lparcfg.c with local_paca - it is okay for iseries_lparcfg_data to be referencing shared_proc with preemption enabled: all cpus should show the same value for shared_proc. Why do other architectures need TRACE_IRQFLAGS_SUPPORT for DEBUG_PREEMPT? I don't know, ppc64 appears to get along fine without it.

If we're coredumping to a pipe we can't trust file->f_pos, we need to maintain the foffset value passed to us.

* | [POWERPC] spufs: Cleanup ELF coredump extra notes logicMichael Ellerman2007-09-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To start with, arch_notes_size() etc. is a little too ambiguous a name for my liking, so change the function names to be more explicit. Calling through macros is ugly, especially with hidden parameters, so don't do that, call the routines directly. Use ARCH_HAVE_EXTRA_ELF_NOTES as the only flag, and based on it decide whether we want the extern declarations or the empty versions. Since we have empty routines, actually use them in the coredump code to save a few #ifdefs. We want to change the handling of foffset so that the write routine updates foffset as it goes, instead of using file->f_pos (so that writing to a pipe works). So pass foffset to the write routine, and for now just set it to file->f_pos at the end of writing. It should also be possible for the write routine to fail, so change it to return int and treat a non-zero return as failure.

* | [POWERPC] spufs: Combine spufs_coredump_calls with spufs_callsMichael Ellerman2007-09-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because spufs might be built as a module, we can't have other parts of the kernel calling directly into it, we need stub routines that check first if the module is loaded. Currently we have two structures which hold callbacks for these stubs, the syscalls are in spufs_calls and the coredump calls are in spufs_coredump_calls. In both cases the logic for registering/unregistering is essentially the same, so we can simplify things by combining the two.

This saves us an indirect branch, but means we have duplicated functions - one for CONFIG_SPU_FS=y and one for =m. This change unifies the spufs syscall path, and provides access to the spufs_calls structure through a get/put pair. At present, the only user of the spufs_calls structure is spu_syscalls.c, but this will facilitate adding the coredump calls later. Everyone likes numbers, right? Here's a before/after comparison with CONFIG_SPU_FS=y, doing spu_create(); close(); 64k times. Before: [jk@cell ~]$ time ./spu_create performing 65536 spu_create calls real 0m24.075s user 0m0.146s sys 0m23.925s After: [jk@cell ~]$ time ./spu_create performing 65536 spu_create calls real 0m24.777s user 0m0.141s sys 0m24.631s So, we're adding around 11us per syscall, at the benefit of having only one syscall path.

* [POWERPC] Fix initialization and usage of dma_maskBenjamin Herrenschmidt2007-08-10
| | | | | | | | | | | | | | | powerpc has a couple of bugs in the usage of dma_masks that tend to break when drivers explicitly try to set a 32-bit mask for example. First, the code that generates the pci devices from the OF device-tree doesn't initialize the mask properly, then our implementation of set_dma_mask() was trying to validate the -previous- mask value, not the one passed in as an argument. This fixes these problems. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] cell: Move SPU affinity init to spu_management_of_opsAndre Detsch2007-08-10
| | | | | | | | | | | | | This patch moves affinity initialization code from spu_base.c to a new spu_management_of_ops function (init_affinity), which is empty in the case of PS3. This fixes a linking problem that was happening when compiling for PS3. Also, some small code style changes were made.

* [POWERPC] Fixes for the SLB shadow buffer codeMichael Neuling2007-08-03
| | | | | | | | | | | | | | On a machine with hardware 64kB pages and a kernel configured for a 64kB base page size, we need to change the vmalloc segment from 64kB pages to 4kB pages if some driver creates a non-cacheable mapping in the vmalloc area. However, we never updated with SLB shadow buffer. This fixes it. Thanks to paulus for finding this. Also added some write barriers to ensure the shadow buffer contents are always consistent.
