Again some fixes, but also optimizations and interesting new features like:
- DWCAPS_NOFOCUS for easy on-screen-keyboard implementation in conjunction with DiVine
- Min/max axis value reporting per event (allowing dynamic ranges for devices like WiiMote)
- Initial support for Renesas SH7723 hardware acceleration

API | IDirectFBInputDevice
- Added DFBInputDeviceAxisInfo(Flags) with DIAIF_ABS_MIN/MAX flags and abs_min/max fields.
- Added DIEF_MIN/MAX and min/max to DFBInputEvent, e.g. for axis boundaries.
API | IDirectFBWindow
- Added DWCAPS_NOFOCUS: window will never get focus or receive key events, unless it grabs them.
Runtime Options
- New option "[no-]software-trace" to show every stage of the software rendering pipeline.
Build Options
- Switch to pkg-config for SDL and FreeType2, thanks to Keith Mok!
Graphics Core
- Only have DSRO_MATRIX be mandatory for now. Other flags no longer prohibit acceleration.
Worst case was when DSRO_SMOOTH_UP/DOWNSCALE was turned on globally via "smooth-upscale" or "smooth-downscale"
runtime option which caused all operations to use software fallbacks, not only StretchBlit()!
Input Core
- Added GetAxisInfo() to InputDriverFuncs to query information about one axis.
Make use of it in input_driver.h only if driver has defined DFB_INPUTDRIVER_HAS_AXIS_INFO
to avoid having to change all input drivers.
- Query axis information from driver and put it into events.
Layer Core
- Set background mode of new contexts to DLBM_DONTCARE.
Pixel Formats
- Rewrote YCbCr<->RGB conversion routines without lookups which are much more expensive on embedded devices.
- Fixed many NV12, NV16 and NV21 code areas, mostly for big endian.
Software Rendering
- Rewrote Dacc_RGB_to_YCbCr_C and Dacc_YCbCr_to_RGB_C using Duff's device with macros.
Conversion also supports 4:4:4 by this change, not optimizing for 4:2:x cases.
- Get rid of YUV tables saving 5k binary size!
- Added optimized Bop_argb_blend_alphachannel_one_invsrc_Aop_argb() -> 6x speed
Utilities
- Added exported dfb_pixelformat_names[] and replaced relevant code.
libdirect
- Important fix for having multiple interface implementations in one module.
- Added file and symbol lookup functions to trace code for external usage.
New functions are direct_trace_lookup_file(), direct_trace_lookup_symbol() and
a convenience function combining the above called direct_trace_lookup_symbol_at().
- Fixed missing magic value in thread structure created for non-direct threads.
Davinci Driver
- In ARGB OSD dithering use task buffer and add missing locks.
- Raise OSD surface pool priority to allocate in frame buffer rather than /dev/mem.
- Workaround broken DSP cache invalidation function.
SH7722 Driver
- Build only for SH4.
- Fixed missing update of rendering destination buffer.
- Fixes for JPEG encoding with conversion, cleanups...
- Fixed software fallback for JPEG decoding to unsupported formats.
SH7723 Driver
- Added support for SH7723 to SH7722 driver and kernel module.
Default WM
- Use min/max values from absolute axis motion events if present.
- Implemented DWCAPS_NOFOCUS.
X11 System
- Update X11 system module with cleaned up code from 1.3.x.
- Fixes in input driver and layer output.
JPEG Image Provider
- Fix direct decoding to NV16 (no to+from RGB) for little endian.
dfbtest_blit
- Added test program for (Stretch)Blit with an image from file.
