* [ARM] alternative copy_to_user: more precise fallback thresholdNicolas Pitre2009-05-301-2/+73
| | | | | | | | | | | | | | | | | | | | | | Previous size thresholds were guessed from various user space benchmarks using a kernel with and without the alternative uaccess option. This is however not as precise as a kernel based test to measure the real speed of each method. This adds a simple test bench to show the time needed for each method. With this, the optimal size treshold for the alternative implementation can be determined with more confidence. It appears that the optimal threshold for both copy_to_user and clear_user is around 64 bytes. This is not a surprise knowing that the memcpy and memset implementations need at least 64 bytes to achieve maximum throughput. One might suggest that such test be used to determine the optimal threshold at run time instead, but results are near enough to 64 on tested targets concerned by this alternative copy_to_user implementation, so adding some overhead associated with a variable threshold is probably not worth it for now.

* [ARM] lower overhead with alternative copy_to_user for small copiesNicolas Pitre2009-05-291-9/+27
| | | | | | | | | | | | | | | | | | | | Because the alternate copy_to_user implementation has a higher setup cost than the standard implementation, the size of the memory area to copy is tested and the standard implementation invoked instead when that size is too small. Still, that test is made after the processor has preserved a bunch of registers on the stack which have to be reloaded right away needlessly in that case, causing a measurable performance regression compared to plain usage of the standard implementation only. To make the size test overhead negligible, let's factorize it out of the alternate copy_to_user function where it is clear to the compiler that no stack frame is needed. Thanks to CONFIG_ARM_UNWIND allowing for frame pointers to be disabled and tail call optimization to kick in, the overhead in the small copy case becomes only 3 assembly instructions. A similar trick is applied to clear_user as well. Signed-off-by: Nicolas Pitre <nico@marvell.com>
* [ARM] alternative copy_to_user/clear_user implementationLennert Buytenhek2009-05-293-0/+158
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements {copy_to,clear}_user() by faulting in the userland pages and then using the regular kernel mem{cpy,set}() to copy the data (while holding the page table lock). This is a win if the regular mem{cpy,set}() implementations are faster than the user copy functions, which is the case e.g. on Feroceon, where 8-word STMs (which memcpy() uses under the right conditions) give significantly higher memory write throughput than a sequence of individual 32bit stores. Here are numbers for page sized buffers on some Feroceon cores: - copy_to_user on Orion5x goes from 51 MB/s to 83 MB/s - clear_user on Orion5x goes from 89MB/s to 314MB/s - copy_to_user on Kirkwood goes from 240 MB/s to 356 MB/s - clear_user on Kirkwood goes from 367 MB/s to 1108 MB/s - copy_to_user on Disco-Duo goes from 248 MB/s to 398 MB/s - clear_user on Disco-Duo goes from 328 MB/s to 1741 MB/s Because the setup cost is non negligible, this is worthwhile only if the amount of data to copy is large enough. The operation falls back to the standard implementation when the amount of data is below a certain threshold. This threshold was determined empirically, however some targets could benefit from a lower runtime determined value for optimal results eventually. In the copy_from_user() case, this technique does not provide any worthwhile performance gain due to the fact that any kind of read access allocates the cache and subsequent 32bit loads are just as fast as the equivalent 8-word LDM.

* [ARM] allow for alternative __copy_to_user/__clear_user implementationsNicolas Pitre2009-05-293-2/+6
| | | | | | | | | | | | | | | This allows for optional alternative implementations of __copy_to_user and __clear_user, with a possible runtime fallback to the standard version when the alternative provides no gain over that standard version. This is done by making the standard __copy_to_user into a weak alias for the symbol __copy_to_user_std. Same thing for __clear_user. Those two functions are particularly good candidates to have alternative implementations for, since they rely on the STRT instruction which has lower performances than STM instructions on some CPU cores such as the ARM1176 and Marvell Feroceon.

Fix by using an appropriately sized valiable to hold the size. [Ralf: Greg's original patch submission identified the issue and fixed one instance in tlb-r4k.c but there there were several more.

| * [ARM] Double check memmap is actually valid with a memmap has unexpected ↵Mel Gorman2009-05-181-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | holes V2 pfn_valid() is meant to be able to tell if a given PFN has valid memmap associated with it or not. In FLATMEM, it is expected that holes always have valid memmap as long as there is valid PFNs either side of the hole. In SPARSEMEM, it is assumed that a valid section has a memmap for the entire section. However, ARM and maybe other embedded architectures in the future free memmap backing holes to save memory on the assumption the memmap is never used. The page_zone linkages are then broken even though pfn_valid() returns true. A walker of the full memmap must then do this additional check to ensure the memmap they are looking at is sane by making sure the zone and PFN linkages are still valid. This is expensive, but walkers of the full memmap are extremely rare. This was caught before for FLATMEM and hacked around but it hits again for SPARSEMEM because the page_zone linkages can look ok where the PFN linkages are totally screwed. This looks like a hatchet job but the reality is that any clean solution would end up consumning all the memory saved by punching these unexpected holes in the memmap. For example, we tried marking the memmap within the section invalid but the section size exceeds the size of the hole in most cases so pfn_valid() starts returning false where valid memmap exists. Shrinking the size of the section would increase memory consumption offsetting the gains. This patch identifies when an architecture is punching unexpected holes in the memmap that the memory model cannot automatically detect and sets ARCH_HAS_HOLES_MEMORYMODEL. At the moment, this is restricted to EP93xx which is the model sub-architecture this has been reported on but may expand later. When set, walkers of the full memmap must call memmap_valid_within() for each PFN and passing in what it expects the page and zone to be for that PFN. If it finds the linkages to be broken, it assumes the memmap is invalid for that PFN. Signed-off-by: Mel Gorman <mel@csn.ul.ie> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

The function to_dma_chan() should be marked inline so that the compiler will eliminate it without warning if it isn't used. arch/arm/plat-s3c24xx/dma.c:1239: warning: 'to_dma_chan' defined but not used Signed-off-by: Ben Dooks <ben-linux@fluff.org>
