STATUS as of Tue, 8 May 2001 19:01:39 +0200
Working :
* Unaccelerated : Depth 8, 15, 16 and 24 are ok. I tested them upto
1280x1024 only as my monitor don't support higher modes.
* Endianess clean, thanks to Romain Dolbeau <dolbeaur@club-internet.fr> for
helping me debug this.
* HW cursor.
* ShadowFb.
* Full 2D Accels.
- Sync.
- Pixmap cache.
- Offscreen pixmaps.
- Clipping.
- Screen to screen copy.
- Solid fills.
- HorVert Solid Lines .
- 8x8 Mono Pattern Fills.
- Color Expansion Fills.
- Images Writes.
- Bitmap Writes using direct FIFO writes with or without FIFO Disconnect.
- Pixmap Writes using direct FIFO writes with or without FIFO Disconnect.
* Appian J2000 second head initialization.
* Xv : Hardware video scaler :
- Needs checking on a big endian machine.
- Needs acceleration to work - there is a hardware bug in YV12 mode.
- Support both dual head and single head, trough gamma or permedia3.
- NOTE: depth 15 and 16 currently broken as I can't figure out the
colorKey equation. From the docs it needs to be padded to 8bits per RGB,
but that doesn't seem to work either. FIXME.
- Attributes are :
- FILTER : None, Partial (X only) or Full filtering.
- COLORKEY : Speaks for itself
- DOUBLE_BUFFER : Speaks for itself
- AUTOPAINT_COLORKEY : Speaks for itself
- MIRROR : X and/or Y Axis mirroring. (NOT DONE)
- ALPHA : (NOT DONE)
- 0 -> FB Only
- 1 -> 25% Video, 75% FB
- 2 -> 75% Video, 25% FB
- 3 -> Video Only
Not Working :
* [NOT POSSIBLE] 2D Accel :
- Solid & Dashed Lines are not possible on glint hardware.
- 8x8 Color Pattern Fill is almost never used.
- Clipping needs cleaning up.
* [TODO] 2D Accel hooks for the Rendering extension :
- Render extension initialization.
- CPUToScreenTexture.
- CPUToScreenAlphaTexture.
