2006-11-01Remove x/y/width/height parameters from Clear functions.Brian Paul
2006-10-18Want to stop passing x/y/width/height to Clear() function.Brian Paul
The coordinates need to be computed after we've got the hw lock. Code updated to: 1. Ignore all/x/y/width/height/ params passed to Clear func. 2. Pass 0,0,0,0,0 to _swrast_Clear() until they're totally removed.

2005-09-03SetBuffer, renderbuffer changesBrian Paul
2005-05-04Major check-in of changes for GL_EXT_framebuffer_object extension.Brian Paul
Main driver impacts: - new code for creating the Mesa GLframebuffer - new span/pixel read/write code Some drivers not yet updated/tested.
2005-03-14When timestamping textures, need to emit the event with SAVAGE_WAIT_3DFelix Kuehling
set. Otherwise the 3D engine may still be using a texture that is being overwritten. In order to minimize the cost of waiting, timestamp textures only when needed: when a texture image changes, when a different texture is bound to a texture unit or when a texture unit is disabled. (Used to be after flushing every command buffer.)
2005-03-06Don't synchronize after each frame. Allow the GPU to be one frameFelix Kuehling
ahead of the CPU for more parallelism of CPU and GPU. Unfortunately there seems to be some broken hardware (like my ProSavageDDR) on which status register updates are delayed sometimes. This leads to very jerky animation if the hardware can buffer more than the current frame. A new option "sync_frames" can be used as a remedy on such broken hardware.
2005-03-06- Fixed two bugs related to DMA buffer handling that showed up with theFelix Kuehling
new DRM version 2.4 and command DMA. - Flush less. - Bumped the driver date.
2005-02-23With Savage DRM version 2.3.x or later use event counters for textureFelix Kuehling
heap aging, similar to the way it's done in the i810 and i855 drivers. This avoids idling the engine on every texture upload.
2005-02-12Make glean's masked clear test pass.Felix Kuehling
2005-02-05- Fixed scissor rectangle not moving with the window (Xorg bug #1731).Felix Kuehling
- Flush buffered primitives before changing scissors. - Require Savage DRM version 2.1.0, so that the broken single-cliprect code can finally rest in peace. - Removed some more dead code.
2005-02-02Fixed flushing of client-side vertex buffers.Felix Kuehling
2005-01-21Small cleanup:Felix Kuehling
* Remove some unused (mostly empty) functions * Added context parameter to WAIT_IDLE_EMPTY[_LOCKED] for consistency * Added debug messages to WAIT_IDLE_EMPTY[_LOCKED] * Don't flush empty command buffers
2005-01-20Added support for ELTS to the _savage_render_stage. Requires at leastFelix Kuehling
Savage DRM version 2.2.0. Otherwise the render stage is disabled.
2005-01-03Added support for floating point depth buffers on Savage4-basedFelix Kuehling
hardware. By also reversing the depth range this can compensate the loss of accuracy of far objects caused by the projective transformation. Software fallbacks work but are slightly slower since floats in a custom (non IEEE) format have to be encoded and decoded. I havn't done anything about polygon offsets yet. There doesn't seem to be an easy way do get it right except making the offset unit as big as the lowest resolution of depth values. For now float depth is disabled by default but can be enabled through driconf (though I have seen only positive effects so far).
2005-01-01Removed all direct hardware access (MMIO, BCI) from the Savage DRIFelix Kuehling
driver. It uses the new DRM version 2.0.x now, which has just been committed to DRM CVS.

2004-05-24WAIT_IDLE_EMPTY in savageSwapBuffers until real frame throttling is possible.Felix Kuehling
2004-05-03get rid of last few XF86DRIClipRectDave Airlie
2004-03-26Enable drawing directly to the (now tiled) front buffer.Felix Kuehling
2004-03-24Make sure hardware culling is disabled for unfilled primitives,Felix Kuehling
points and lines.
2004-03-24Buffer vertices and emit them in batches. Still using conventional drawingFelix Kuehling
commands, no vertex DMA.
2004-03-21unsigned int -> uint32_t, unsigned char -> uint8_t where the size matters.Felix Kuehling
A bit more cosmetics. Improved state emit on Savage 3D/IX/MX.
2004-03-20Fixed MAXFIFO_S4. Removed WAIT_IDLE_EMPTY from savage_BCI_swap which resultedFelix Kuehling
in another small speedup. Fixed a problem that was masked by that WAIT_IDLE_EMPTY: - flush command buffer and WAIT_IDLE_EMPTY before uploading textures
2004-03-04Clearing rectangle was one too big in each direction.Felix Kuehling
2004-02-29Reorganized hardware state data structures and state emission. Don't trackFelix Kuehling
which registers changed in all the functions that change the state. Instead check which registers changed in the end when the hardware state is updated. Tried to avoid cosmetic (whitespace) changes in this commit.
2004-02-22Imported the Savage DRI driver from the savage-2-0-0-branch of DRI CVSFelix Kuehling
with modifications to make it work with current Mesa 6.
