The spufs_coredump_read array is NULL terminated, and we also store the size. We only need one or the other, and the other arrays in file.c are NULL terminated, so do that.

Because the SPU coredump code might be built as part of a module (spufs), we have a stub which is called by the coredump code, this routine then calls into spufs if it's loaded. 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.

The routine to dump the local store, __spufs_mem_read(), does not take the spu_lslr_RW value into account - so we shouldn't check it when we're calculating the size either.

Unfortunately GDB expects some of the SPU coredump values to be identical in format to what is found in spufs. This means we need to dump some of the values as ASCII strings, not the actual values. Because we don't know what the values will be, we always print the values with the format "0x%.16lx", that way we know the result will be 19 bytes. do_coredump_read() doesn't take a __user buffer, so remove the annotation, and because we know that it's safe to just snprintf() directly to it.

The spufs_coredump_reader array contains the size of the data that will be returned by the read routine. Currently these are specified as literals, and though some are obvious, sizeof(u32) == 4, others are not, 69 * 8 == ??? Instead, use sizeof() whatever type is returned by each routine, or in the case of spufs_mem_read() the #define LS_SIZE.

It makes sense to stop the SPU processes as soon as possible. Also if we dont acquire_saved() I think there's a possibility that the value in csa.priv2.spu_lslr_RW won't be accurate.

Remove the ctx_info struct entirely, and also the ctx_info_list. This fixes a race where two processes can clobber each other's ctx_info structs.

Extract the logic for searching through the file descriptors for spu contexts into a separate routine, coredump_next_context(), so we can use it elsewhere in future. In the process we flatten the for loop, and move the NOSCHED test into coredump_next_context().

At present, a built-in spufs will not use the spufs_calls callbacks, but directly call sys_spu_create. 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.

Affinity reference point location (gang->aff_ref_spu) is reset when the whole gang is descheduled. However, the last member of a gang can be descheduled while we are trying to schedule another member of the gang. This was leading to a race condition, and the code was using gang->aff_ref_spu in an unsafe manner. 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.

According to the comment in spufs_init_isolated_loader(), the isolated loader should be aligned on a 16 byte boundary. ARCH_{KMALLOC,SLAB}_MINALIGN is not defined so only 8 byte alignment is guaranteed. This enforces alignment via __get_free_pages.

This patch adds the clrsetbits_xxx() macros, which are used to set and clear multiple bits in a single read-modify-write operation. Specify the bits to clear in the 'clear' parameter and the bits to set in the 'set' parameter. These macros can also be used to set a multiple-bit bit pattern using a mask, by specifying the mask in the 'clear' parameter and the new bit pattern in the 'set' parameter. There are big-endian and little-endian versions for 8, 16, 32, and 64 bits. Signed-off-by: NTimur Tabi <timur@freescale.com> Signed-off-by: NKumar Gala <galak@kernel.crashing.org>
