- Use the CMDFIFO wakeup on vertical retrace only for the 3D mode.
- Report screen mode change (2D, 3D, mixed).
- Added BX_ERRORs for currently unsupported pixel format conversion.
- Only continue bitblt operation if width and height is > 0 after clipping.
- Temporary hack: Processing CMDFIFO packets directly after completion fixes
some display issues (FIXME: 3D mode should work like Voodoo2).
- Handling variable 'gui_update_pending' like Voodoo 1/2 fixes 3D display
flicker. Simplified first stage of the update() code. Some 3D display issues
still need to be investigated.
- Added missing 16-bit write support in 3D memory space.
- Added separate method for linear FB writes und use it for CMDFIFO packet type
5, destination code 0. Added minimal "byte disable" support in this code.
- Added Banshee specific registers in register_w() since they use the same
addresses as the Voodoo2 CMDFIFO config registers in register_w_common().
Now the fullscreen 3D mode is basicly working. The display flickers sometimes
and the desktop is possibly unusable after leaving 3D mode. This may be
caused by the still incorrect CMDFIFO implementation.
- Split the host-to-screen method in two ones: one for the pattern case (ternary
ROPs) and one optimized for the standard case (binary ROPs).
- Improved the foreground/background color handling for bitblt operations.
- Prepared update() code for 3D support (not yet working).
- Attempt to fix the LFB base address.
- CMDFIFO packet type 5: Added support for destination code 0 (linear FB).
- Always check if CMDFIFO is still enabled in the FIFO thread loop.
- Fixed offset for 3D register access (3D still not usable).
- Apply FBI mask when accessing memory in tiled desktop mode to avoid segfault.
- Added support for 16-bit writes to LFB.
- Don't access Voodoo2 CMDFIFO in Banshee mode.
- Set up the correct chipmask for Banshee (it has only one TMU).
- Fixed CMDFIFO enable message (using index #0 and #1).
dwords required for host-to-screen operations. There are no related error
messages in the log when I test 8, 24 and 32 bpp modes. There are still display
errors caused by buggy code, incorrect CMDFIFO implemenation or undocumented
features. The 16 bpp mode is still unusable possibly caused by CMDFIFO. 3D mode
testing cannot start before this mode is okay.
- Disabled voodoo_update() function completely and added the required code to
the vertical timer handler (Voodoo 1/2).
- Added new method banshee_blt_execute() to reduce code duplication.
- Added support for the pattern x/y start offset (Banshee).
