32bd0f8ab1 Greyscale library: Optionally put the greyscale ISR on COP on portalplayertargets (only use with the grey_info structure in IRAM atm\!). This speeds up doom by ~50%, and makes mpegplayer work without stuttering audio on targets using it (measured on iPod 2nd Gen and Mini 2nd Gen). It needs corelocking certain functions in the LCD driver on 1st/2nd Gen.

8399749412 1st/2nd Gen: Backlight inversion needs to be protected from interrupts, because it can happen any time, even while the greyscale lib or something else is writing to the LCD from an ISR. Also make backlight inversion only hit the LCD if necessary. * Use register definition in the 1st..3rd Gen backlight drivers.

b073f0cfc1 LCD driver tweaks for greyscale iPods: * Use 1/7 bias, 5x step-up and the highest step-up frequency on all 1st..3rd gen iPods, simplifying the driver this way. The default contrast for those iPods has changed - reset settings in case the display becomes unreadable. * Set n-line inversion drive to 9 lines, improving image quality on 1st..3rd gen iPods somewhat.

e249ecc85b iPod 1st..3rd Gen and Mini 1st Gen fixes/improvements: * Remove the unnecessary 'reverse' parameter from handle_scroll_wheel() (a remnant from IPL that's not needed in rockbox), and make it static. * Wheel power saving on 1st Gen needs to disable the respective GPIO interrupts as well, otherwise every wheel check might fire interrupts. Make wheel power saving more self-contained as well.

af395f4db6 Do core interrupt masking in a less general fashion and save some instructions to decrease size and speed things up a little bit. Small fix to a few places where interrupts would get enabled again where they shouldn't have been (context switching calls when disabled).

ef62d6891a Split up app.lds to the respective target directories. The portalplayer devices replicate app.lds since their target tree doesn't follow a syntax typical to the newer arm targets - the portalplayers could be cleaned up further. boot.lds and plugin.lds still need to be cleaned up.

054447f9e6 Commit FS#8379 by Andree Buschmann. Disables much of the remaining unneeded hardware on PP50xx targets (Ipods, Sansa, H10s, etc) resulting in a large savings in power and consequent increase in battery life. Results vary from target to target and from codec to codec, but we now approach the OF runtime on several PP devices. For now, leave base CPU clock at 30MHz, although further savings is possible with some codecs if clock is reduced. Additionally, fix battery capacity on c200 and use my measurements to improve runtime estimation for Sandisk targets.

6a56c14e17 Greyscale library: Changed the internal data format once more (separated pixel values and phases), allowing for further optimisation of drawing, scrolling etc. * Optimised grey phase blitting in the core reduces CPU load on all architectures, most significantly on coldfire. Previous version was too slow to keep up at 45MHz, leading to unwanted graininess (update frequency was halved). Also fixed screendump on 2bpp targets with vertical pixel packing.

feb5b15e9b All-new greyscale library, replacing the old one. Features: (1) Drawing/updating is faster than the old grayscale lib at full depth. (2) Always 129 shades instead of 2..33 shades. (3) No graininess caused by frequent updates (mpegplayer, doom, ...). (4) Needs less memory than the old grayscale lib at full depth. * The tradeoff is slightly higher CPU load in the ISR (frames are calculated 'live') and an extra function in the core. * Ported all plugins which used the graylib to use the new one. * Some slight optimisations for archos and H1x0 LCD update.

9daf658ef1 iPod Video LCD driver: Reintroduce the simple method of waiting for update completion for use in the bootloader, because bootloaders don't enable interrupts and hence the tick task won't work. Slower than the full driver, but still faster than the old one, because it first transfers the data, and then polls the BCM.

a9b2fb5ee3 Finally full multicore support for PortalPlayer 502x targets with an eye towards the possibility of other types. All SVN targets the low-lag code to speed up blocking operations. Most files are modified here simple due to a name change to actually support a real event object and a param change to create_thread. Add some use of new features but just sit on things for a bit and leave full integration for later. Work will continue on to address size on sensitive targets and simplify things if possible. Any PP target having problems with SWP can easily be changed to sw corelocks with one #define change in config.h though only PP5020 has shown an issue and seems to work without any difficulties.
