Fix empty commit: Add grayscale support for ARM in vertical packing format.

2007-09-22T23:37:58+00:00

Enable grayscale for Iriver ifp. Fix timer_unregister for PNX0101.

Grayscale lib: Using a 32x32->32 bit multiplication is better on ARM, as 16x16->32 bit isn't a single instruction. Renamed the macro for pointing out that it's not necessarily 16 bit anymore, and to avoid collisions with similar macros in plugins.

* Use fast multiplication macro in some more places. * Better pipelining on SH1.

Better implementation of the new greyscale algorithm. A bit faster (+2% on iPod and Archos, +7% on Iriver H1x0), and more straightforward. * Fixed garbage display when a plugin switches on the overlay before drawing anything.

New algorithm for grayscale buffer updates which is faster for large buffer depths. Speedup (unbuffered, depth==32): +8% on H1x0, +17% on Recorder (depth==24), and +83% on iPod Mini.

ARM targets: Shave off one instruction from the multiply-by-75.

* Assembler optimised gray_update_rect() and writearray() for arm (greyscale iPods). * Some slight optimisations for coldfire (H1x0) and SH1 (archos). * Comment and formatting cleanup.

Grayscale library ported to the grayscale iPods, first version. Added C reference versions of gray_update_rect() for both horizontal and vertical pixel packing. gray_update_rect() and gray_ub_gray_bitmap_part() not yet assembler optimised. Grayscale screendump doesn't work yet. * Fixed button assignments for iPod in grayscale.c
