| | * | | | [ARM] pxa/sharpsl_pm: merge pxa-specific code into generic oneDmitry Eremin-Solenikov2009-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As pxa now is the only user of sharpsl_pm we can drop several startup functions into generic code thus dropping several global functions.

The cpufreq will ask for a "vcc_core" regulator to the regulator framework. If a regulator is found at probe time, it will be used with values specified in PXA270 Electrical, Mechanical, and Thermal Specifications. If not, it will be assumed for now that frequency change will work without voltage control. This assumes that the IPL/SPL installs sane values to an existing voltage regulator (ie. voltage high enough to support the full range).

Zylonite needs 32, ASIC3 based boards need 70. My problem is still that due to the way IRQ_GPIO is hardcoded, ASIC3 based boards need 70 IRQs starting at IRQ_BOARD_START. If I define ASIC3 IRQs similar to LoCoMo or SA1111, things break as soon as something selects PXA_HAVE_BOARD_IRQS. Increasing the default number of board IRQs to 70 instead doesn't seem very nice.

| | * | | | | [ARM] alternative copy_to_user: more precise fallback thresholdNicolas Pitre2009-05-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Pitre2009-05-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
