| * | | [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.

| * | | [POWERPC] spufs: Internal __spufs_get_foo() routines should take a spu_context *Michael Ellerman2007-09-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SPUFS attribute get routines take a void * because the generic attribute code doesn't know what sort of data it's passing around. However our internal __spufs_get_foo() routines can take a spu_context * directly, which saves plonking it in and out of a void * again.

Unfortunately the stub returns -ENOSYS if spufs is not loaded, which is interpreted by the coredump code as an extra note size of -38 bytes. This leads to a corrupt core dump. If spufs is not loaded there will be no SPU ELF notes to write, and so the extra notes size will be == 0.

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.

By holding the gang->aff_mutex a little bit longer, and increment gang->aff_sched_count (which controls when gang->aff_ref_spu should be reset) a little bit earlier, the problem is fixed.

The following includes were removed: <asm/amigappc.h> <asm/bootinfo.h> <asm/ppcboot.h> <asm/ppc_sys.h> <asm/residual.h> <asm/m8260_pci.h> This also caused platforms/embedded6xx/mpc7448_hpc2.h to no longer be needed and thus removed.

Previous scheme just pushed out the current timebase from the giving core to all cores without caring if they wanted it or not, nor checking if they'd taken it. The taking side didn't make sure the giving side had provided a value yet either. In other words, it was completely broken.
