2009-09-04intel: Also get the DRI2 front buffer when doing front buffer reading.Eric Anholt
(cherry picked from commit df70d3049a396af3601d2a1747770635a74120bb)
2009-06-17i915: Use Stencil.Enabled instead of Stencil._Enabled in DrawBuffers.Eric Anholt
The _Enabled field isn't updated at the point that DrawBuffers is called, and the Driver.Enable() function does the testing for stencil buffer presence anyway. bug #21608 for Radeon (cherry picked from commit 4c6f82989983eecc0b3b724716cb3bcb675664c5)
2009-05-11Test either GL_FRONT_LEFT or GL_FRONT for front-buffer renderingIan Romanick
For non-stereo visuals, which is all we support, we treat GL_FRONT_LEFT as GL_FRONT. However, they are technically different, and they have different enum values. Test for either one to determine if we're in front-buffer rendering mode. This fix was suggested by Pierre Willenbrock.

2009-04-24intel / DRI2: When available, use DRI2GetBuffersWithFormatIan Romanick
This interface gives the driver two important features. First, it can allocate the (fake) front-buffer only when needed. Second, it can tell the buffer allocator the format of buffers being allocated. This enables support for back-buffer and depth-buffer with different bits per pixel.

2009-04-14DRI2: Don't fault on NULL DrawBufferIan Romanick
It is possible for ctx->DrawBuffer to be NULL, so don't fault when that happens. This change is not being committed to master because it doesn't appear to be necessary there. Signed-off-by: Ian Romanick <ian.d.romanick@intel.com> Cherry picked from mesa_7_4_branch, commit 49e0c74ddd91900fc4effb6d305d56e0563b456d
2009-04-09intel / DRI2: Track and flush front-buffer renderingIan Romanick
Track two flags: whether or not front-buffer rendering is currently enabled and whether or not front-buffer rendering has been enabled since the last glFlush. If the second flag is set, the front-buffer is flushed via a loader call back. If the first flag is cleared, the second flag is cleared at this time.

Fix the last merge fix, had the blocks ordered incorrectly.

Bah, applied the patches in the wrong order, not Owain's fault...
2009-01-23intel: fix vblank crtc selection with DRI1 when only one pipe is enabled.Owain Ainsworth
On Mobile chipsets, we often enable PipeB instead of PipeA, but the test in here was insufficient, falling back to pipe A if the area intersection returned zero. Therefore, in the case where a window went off to the top of the left of the screen, it would freeze, waiting on the wrong vblank. Fix this mess by checking the sarea for a crtc being zero sized, and in that case always default to the other one.
2009-01-23intel: Prevent an "irq is not working" printf when only pipe B is enabled.Owain G. Ainsworth
intelMakeCurrent is called before intelWindowMoved (in fact, it calls it), so calculation of the correct vblank crtc has not happened yet. Fix this by making a function that fixes up a set of vblank flags and call if from both functions.
2009-01-22intel: remove/disable the "paired depth/stencil" codeBrian Paul
We only allow combined depth+stencil renderbuffers so the complicated code for splitting and combining separate depth and stencil buffers is no longer needed.

2009-01-20[intel] Go back to using the typedef for the sarea structTimo Aaltonen
The upstream linux kernel headers and libdrm kernel headers disagree on the tag name for the sarea struct: _drm_i915_sarea vs drm_i915_sarea. They both typedef it to drm_i915_sarea_t though, so just use that.
2009-01-20Remove intel pageflipping support in its entirety.Owain G. Ainsworth
It's been broken and deprecated for a while, so it's time to die. This has the wonderful benefit of cleaning up the code a fair amount; making it marginally less twisty. I'm unsure if the for loops in IntelWindowMoved are still needed.
2008-12-23Remove third buffer support from Mesa.Dave Airlie
This is part of the deprecated pageflipping infrastructure.
2008-10-28intel: Don't keep intel->pClipRects, and instead just calculate it when needed.Eric Anholt
This avoids issues with dereferencing stale cliprects around intel_draw_buffer time. Additionally, take advantage of cliprects staying constant for FBOs and DRI2, and emit cliprects in the batchbuffer instead of having to flush batch each time they change.
2008-10-07intel: Push flushing for cliprects changes down into the cliprects changes.Eric Anholt
This lets us short-circuit when we're leaving the same cliprects in place, which becomes quite common with metaops clears, and may be useful for some of our FBO paths.

2008-07-22intel: fix buffer swaps and enable page flipping on 965Jesse Barnes
Some buffer swap intel render buffer fields (pf_num_pages & vbl_pending) are also used for page flipping, so enable the code that sets & updates them on 965. This allows buffer swaps and page flips to work on 965 and prevents hangs in LOCK_HARDWARE in the buffer swap case due to an uninitialized vbl_pending field. Fixes FDO #16118.

2008-02-29Use __DRIextension mechanism providing loader functionality to the driver.Kristian Høgsberg
Instead of passing in a fixed struct, the loader now passes in a list of __DRIextension structs, to advertise the functionality it can provide to the driver. Each extension is individually versioned and can be extended or phased out as the interface develops.

2008-01-10[intel] Only flush batch when changing draw buffers, not every cliprect update.Eric Anholt
The previous code would reference freed memory on window moves.
2008-01-10[intel] Add more cliprect modes to cover other meanings for batch emits.Eric Anholt
The previous change gave us only two modes, one which looped over the batch per cliprect (3d drawing) and one that didn't (state updeast). However, we really want 4: - Batch doesn't care about cliprects (state updates) - Batch needs DRAWING_RECTANGLE looping per cliprect (3d drawing) - Batch needs to be executed just once (region fills, copies, etc.) - Batch already includes cliprect handling, and must be flushed by unlock time (copybuffers, clears). All callers should now be fixed to use one of these states for any batchbuffer emits. Thanks to Keith Whitwell for pointing out the failure.
2008-01-09[intel] Clean up cliprect handling in intel drivers.Eric Anholt
In particular, batch buffers are no longer flushed when switching from CLIPRECTS to NO_CLIPRECTS or vice versa, and 965 just uses DRM cliprect handling for primitives instead of trying to sneak in its own to avoid the DRM stuff. The disadvantage is that we will re-execute state updates per cliprect, but the advantage is that we will be able to accumulate larger batch buffers, which were proving to be a major overhead.
2008-01-06Replace gl_framebuffer's _ColorDrawBufferMask with _ColorDrawBufferIndexesBrian
Each array element is now a BUFFER_x token rather than a BUFFER_BIT_x bitmask. The number of active color buffers is specified by _NumColorDrawBuffers. This builds on the previous DrawBuffer changes and will help with drivers implementing GL_ARB_draw_buffers.
2008-01-06Simplify ctx->_NumColorDrawBuffers, _ColorDrawBuffers and fix bug 13835.Brian
These fields are no longer indexed by shader output. Now, we just have a simple array of renderbuffer pointers. If the shader writes to gl_FragData[i], send those colors to the N _ColorDrawBuffers. Otherwise, replicate the single gl_FragColor (or the fixed-function color) to the N _ColorDrawBuffers. A few more changes and simplifications can follow from this...
