* Add drirenderbuffer.c to COMMON_SOURCESAdam Jackson2005-05-041-0/+1
|
* Major check-in of changes for GL_EXT_framebuffer_object extension.Brian Paul2005-05-047-26/+173
| | | | | | | Main driver impacts: - new code for creating the Mesa GLframebuffer - new span/pixel read/write code Some drivers not yet updated/tested.
* Bumped the Savage driver date (a bit late) to mark S3TC support.Felix Kuehling2005-05-011-1/+1
|
* Fixed and cleaned up programming of watermark registers. There may beFelix Kuehling2005-05-012-53/+75
| | | | | | a marginal speedup, but I'm not sure this has the same effect on all hardware. Tested on Savage IX and ProSavageDDR. For experimenting with different values see the macros at the start of savagestate.c.
* Added S3TC support to the Savage driver with some help from Mark Cass'sFelix Kuehling2005-04-302-31/+200
| | | | | | | S3TC support for an older driver version. On Savage3D/IX/MX GL_EXT_texture_compression_s3tc can't be enabled because DXT3 and DXT5 are not supported. However GL_S3_s3tc is enabled on all Savage chips. Tested on a Savage IX and a ProSavageDDR
* Software fallback for glColorMask. Can be avoided on Savage4 when allFelix Kuehling2005-04-242-41/+22
| | | | | | channels are masked (disable draw update). Bumped driver date to reflect recent correctness fixes. The driver now passes all glean tests except exactRGBA on both Savage4 and Savage3D-based cards.
* Fixed a segfault introduced by Keith's pipeline changes.Felix Kuehling2005-04-231-1/+2

* Texturing fixes for Savage3D/MX/IX:Felix Kuehling2005-04-233-24/+240
| | | | | | | | | | | | | | | | | - force emitting texAddr when the texture image changed (flush caches) - set transparent texture color key to something improbable (couldn't find a way to disable it completely) - fixed texture environment modes GL_DECAL and GL_REPLACE - made texture environment mode GL_BLEND a software fallback - added two custom texture formats for promoting from GL_ALPHA to ARGB8888 and 4444. Since the hardware can't be made to ignore the RGB color components, set them to 1 instead of 0. This gives the correct results - disabled GL_EXT_texture_env_add on Savage3D/MX/IX - map both GL_CLAMP and GL_CLAMP_TO_EDGE to hardware mode "wrap". It doesn't match either mode exactly by the spec, so we should either fall back on both or none. I chose the latter. - fall back to software when s and t wrapping modes differ (hardware has only one bit for both)
* First pass at updating these drivers with pipeline_stage struct changes.Keith Whitwell2005-04-221-44/+17

* Fixed some suspicious pointer casts that caused lots ofFelix Kuehling2005-04-215-19/+19
| | | | | | compile-time-warnings on x86-64. Not tested on x86-64 yet, but a good thing in general, so I'm giving up waiting for feedback. See also https://bugs.freedesktop.org/show_bug.cgi?id=2924.
* Fixed TexEnv modes GL_BLEND and GL_ADD on Savage4-based cards. DisabledFelix Kuehling2005-04-213-24/+71
| | | | | the use of hardware texture format I8 as it produces garbage at least on ProSavageDDR.
* Fixed segfault due to an off-by-one error in SAVAGE_TEX_MAXLEVELS.Felix Kuehling2005-03-241-1/+1
|
* Initialize texture addresses to something valid.Felix Kuehling2005-03-231-0/+20
|
* When timestamping textures, need to emit the event with SAVAGE_WAIT_3DFelix Kuehling2005-03-142-27/+41
| | | | | | | | 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.)
* Updated savage_dri.h from Xorg CVS. This removes definitions that areFelix Kuehling2005-03-131-81/+0
| | | | | not part of the DDX->DRI interface and should never have been in this file in the first place.
* Removed savagedma.[ch]. They have been unused for a while and were onlyFelix Kuehling2005-03-122-261/+0
| | | | | kept around for reference. Now that command DMA is implemented in the DRM module they are no longer needed.
* - Flush before updating the timestamp of a texture heap from a bound texture.Felix Kuehling2005-03-101-3/+21
| | | | | | | - Flush before using a new texture or before disabling a texture unit, because savageFlushCmdBuf can only update the timestamp of the last used texture. This fixes corruption in quake2 with single-textured lighting.
* If the texture image changed force emitting the texture address, evenFelix Kuehling2005-03-091-2/+10
| | | | | if it didn't change. This seems to flush texture cashes. Fixes multi-textured lighting in quake2.
* Don't synchronize after each frame. Allow the GPU to be one frameFelix Kuehling2005-03-063-14/+17
| | | | | | | | | 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.
* - Fixed two bugs related to DMA buffer handling that showed up with theFelix Kuehling2005-03-065-29/+14
| | | | | | new DRM version 2.4 and command DMA. - Flush less. - Bumped the driver date.
* Don't forget to update a heap's timestamp when a texture image isFelix Kuehling2005-02-231-2/+15
| | | | | | changed. Other drivers don't need to do this because they're swapping modified textures out of texture memory, which implies a timestamp update.
* With Savage DRM version 2.3.x or later use event counters for textureFelix Kuehling2005-02-233-1/+30
| | | | | heap aging, similar to the way it's done in the i810 and i855 drivers. This avoids idling the engine on every texture upload.
* Fall back properly when GL_COLOR_LOGIC_OP is enabled and != GL_COPY.Felix Kuehling2005-02-122-13/+16
| | | | Add missing per-primitive fallback for polygon stipple.
* Offset LOD bias by about 0.3 to match software rendering more closely.Felix Kuehling2005-02-121-18/+18
| | | | Another small tweak to subtile upload (mostly cosmetic).
* Make glean's masked clear test pass.Felix Kuehling2005-02-121-1/+15
|
* Savage3D-based chips seem so use a constant tile stride of 2048 forFelix Kuehling2005-02-121-1/+10
| | | | | vertically incomplete tiles, but only if the color depth is 32bpp. Nobody said this was supposed to be logical!
* Fixed stride of incomplete tiles.Felix Kuehling2005-02-091-1/+1
|
* Disable vertex DMA on SuperSavages.Felix Kuehling2005-02-051-5/+15
|
* - Fixed scissor rectangle not moving with the window (Xorg bug #1731).Felix Kuehling2005-02-056-158/+47
| | | | | | | - 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.
* Added an option texture_heaps that allows selecting which texture heapsFelix Kuehling2005-02-041-2/+18
| | | | | | | will be used. Implemented this option in the Savage driver. On my ProSavageDDR uploads to AGP memory are about 1.5 times as fast as uploads to card memory. On non-IGP hardware the difference may be even bigger. Now mplayer -gl is getting really usable.
* Made subtile upload a template. This speeds up tiled texture uploads byFelix Kuehling2005-02-041-6/+41
| | | | about a factor 1.3.
* Check for heap == NULL before driSetTextureSwapCounterLocation.Felix Kuehling2005-02-021-2/+5
|
* Fixed flushing of client-side vertex buffers.Felix Kuehling2005-02-021-52/+53
|
* Fixed some debug output that was unconditionally enabled.Felix Kuehling2005-02-021-5/+6
|
* Bug #2428: #ifdef GLX_DIRECT_RENDERING in DRI drivers is pointless.Adam Jackson2005-01-312-7/+0
|
* * Fixed uploading of textures of certain sizes.Felix Kuehling2005-01-294-26/+168
| | | | | | | | * When glTexSubImageND is used, track the set of changed tiles in a bit vector and upload only dirty tiles later. This should improve the performance of dynamic light maps and gl movie player plugins. * Renamed debug item "lru" to "tex". Indicate which levels are uploaded completely or partially.
* Converted the Savage texture management to use Ian's common texmem code.Felix Kuehling2005-01-244-575/+239
|
* Fixed initialization of draw destination to front buffer on singleFelix Kuehling2005-01-231-49/+19
| | | | | | | buffered visuals. Also don't change span draw/read buffers in savageDDDrawBuffer. Now glean's polygon offset test works (and PASSes with fixed point depth buffer) with single buffered visuals without winding up in an infinite loop.
* My last attempt to fix polygon offsets with the reversed viewport depthFelix Kuehling2005-01-232-3/+1
| | | | | | | | | range used by the savage driver by negating ctx->MRD broke polygon offsets with software fallbacks. This one adds a REVERSE_DEPTH parameter to t_dd_tritmp.h (defaults to 0) that allows reversing polygon offsets for hardware rendering but not for software fallbacks. For software fallbacks depth values are reversed after polygon offsets have been applied by the depth span functions.
* Fixed polygon offset with reversed viewport depth range.Felix Kuehling2005-01-221-0/+3
|
* Small cleanup:Felix Kuehling2005-01-216-56/+30
| | | | | | | * 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
* * Added options for disabling the fast path (render stage) and vertex DMAFelix Kuehling2005-01-205-15/+42
| | | | | | * Fixed disabling of the render stage * Added debug output for per-primitive fallbacks * Bumped driver date
* Added support for ELTS to the _savage_render_stage. Requires at leastFelix Kuehling2005-01-205-31/+178
| | | | Savage DRM version 2.2.0. Otherwise the render stage is disabled.
* Added a fast path for emitting unclipped primitives directly to aFelix Kuehling2005-01-165-173/+375
| | | | | | | | vertex buffer. ELTS are not supported yet (missing functionality in the DRM). You need at least Savage DRM version 2.1.3, which fixes a bug that screwed up triangle fans and strips. Moved the texture normalization stage to savagerender.c.
* Converted to use spantmp2.h.Felix Kuehling2005-01-151-74/+32
|
* Make sure DMA buffers are released in savageDestroyContext. UsuallyFelix Kuehling2005-01-131-1/+2
| | | | | the DRM would reclaim DMA buffers, but if one process creates and destroys many contexts it can still run out of DMA buffers.
* Fixes to cope with the lack of AGP textures. This is all that's neededFelix Kuehling2005-01-103-14/+21
| | | | to support PCI Savages on the Mesa side. Bumped driver date.
* * Flush and wait in per-primitive fallback functions. Fixes flickeringFelix Kuehling2005-01-081-97/+206
| | | | | | | stars in glplanet. * Refactored vertex format choosing code. Improved the Savage4 version to choose a format suitable for DMA (size = 32bytes) whenever possible.
* Added state debugging option (SAVAGE_DEBUG=state).Felix Kuehling2005-01-083-1/+5
| | | | | Fixed: Use savageEmitChangedRegs instead of savageEmitContiguousRegs for emitting Savage4.
* Fixed: ptex drawing functions were overridden with standard drawingFelix Kuehling2005-01-071-3/+3
