2011-01-07intel: Use the _BaseFormat from MESA_FORMAT_* in renderbuffer setup.Eric Anholt
2011-01-07i915: Don't claim to support AL1616 when neither 830 nor 915 does it.Eric Anholt
Fixes an abort in fbo-generatemipmap-formats.
2011-01-07intel: Add a vtbl hook for determining if a format is renderable.Eric Anholt
By relying on just intel_span_supports_format, some formats that aren't supported pre-gen4 were not reporting FBO incomplete. And we also complained in stderr when it happened on i915 because draw_region gets called before framebuffer completeness validation.
2011-01-07intel: expose ARB_framebuffer_object in the i915 driver.Eric Anholt
ARB_fbo no longer disallows mismatched width/height on attachments (shouldn't be any problem), mixed format color attachments (we only support 1), and L/A/LA/I color attachments (we already reject them on 965 too). It requires Gen'ed names (driver doesn't care), and adds FramebufferTextureLayer (we don't do texture arrays). So it looks like we're already in the position we need to be for this extension. Bug #27468, #32381.
2011-01-06i965: skip too small size mipmapZou Nan hai
this fixes doom3 crash.
2011-01-05intel: Always allocate miptrees from level 0, not tObj->BaseLevel.Eric Anholt
BaseLevel/MaxLevel are mostly used for two things: clamping texture access for FBO rendering, and limiting the used mipmap levels when incrementally loading textures. By restricting our mipmap trees to just the current BaseLevel/MaxLevel, we caused reallocation thrashing in the common case, for a theoretical win if someone really did want just levels 2..4 or whatever of their texture object. Bug #30366
2011-01-05intel: Drop unused first/lastlevel args to miptree_create_for_region.Eric Anholt
We're always making a single-level, 0-baselevel miptree.
2011-01-05intel: Clarify first_level/last_level vs baselevel/maxlevel by deletion.Eric Anholt
This has always been ugly about our texture code -- object base/max level vs intel object first/last level vs image level vs miptree first/last level. We now get rid of intelObj->first_level which is just tObj->BaseLevel, and make intelObj->_MaxLevel clearly based off of tObj->_MaxLevel instead of duplicating its code (incorrectly, as image->MaxLog2 only considers width/height and not depth!)
2011-01-05i915: Implement min/max lod clamping in hardware on 8xx.Eric Anholt
This avoids 8xx-specific texture relayout for min/max lod changes. One step closer to avoiding relayout for base/maxlevel changes!
2011-01-05intel: Drop TEXTURE_RECTANGLE check in miptree layout setup.Eric Anholt
It's already handled by our non-mipmapped MinFilter, since TEXTURE_RECTANGLE is always NEAREST or LINEAR.
2011-01-05intel: Clean up redundant setup of firstLevel.Eric Anholt
It's always BaseLevel (since TEXTURE_RECTANGLE's baselevel can't be changed from 0), except for 8xx minlod hilarity.
2011-01-05intel: Drop a check for GL_TEXTURE_4D_SGIS.Eric Anholt
The SGIS_texture4D extension was thankfully never completed, so we couldn't implement it if we wanted to.
2011-01-05i965: use BLT to clear buffer if possible on SandybridgeXiang, Haihao
This fixes https://bugs.freedesktop.org/show_bug.cgi?id=32713
2011-01-04i965: Add support for SRGB DXT1 formats.Eric Anholt
This makes fbo-generatemipmap-formats GL_EXT_texture_sRGB-s3tc match fbo-generatemipmap-formats GL_EXT_texture_compression_s3tc and swrast in bad DXT1_RGBA alpha=0 handling, but it means we won't unpack and repack someone's textures into uncompressed SARGB8 format.
2011-01-04intel: Merge our choosetexformat fallbacks into core.Eric Anholt
We now share the type/format -> MESA_FORMAT_* mappings with software mesa, and the core supports most of the fallbacks hardware drivers will want.
2011-01-04intel: When validating an FBO's combined depth/stencil, use the given FBO.Eric Anholt
We were looking at the current draw buffer instead to see whether the depth/stencil combination matched. So you'd get told your framebuffer was complete, until you bound it and went to draw and we decided that it was incomplete.
2011-01-04intel: Fix segfaults from trying to use _ColorDrawBuffers in FBO validation.Eric Anholt
The _ColorDrawBuffers is a piece of computed state that gets for the current draw/read buffers at _mesa_update_state time. However, this function actually gets used for non-current draw/read buffers when checking if an FBO is complete from the driver's perspective. So, instead of trying to just look at the attachment points that are currently referenced by glDrawBuffers, look at all attachment points to see if they're driver-supported formats. This appears to actually be more in line with the intent of the spec, too. Fixes a segfault in my upcoming fbo-clear-formats piglit test, and hopefully bug #30278
2011-01-03intel: Use tri clears when we don't know how to blit clear the format.Eric Anholt
Bug #32207. Fixes ARB_texture_rg/fbo-clear-formats (see my fbo-clear-formats piglit branch currently)
2011-01-03intel: Handle forced swrast clears before other clear bits.Eric Anholt
Fixes a potential segfault on a non-native depthbuffer, and possible accidental swrast fallback on extra color buffers.
2010-12-27i965: Internally enable GL_NV_blend_square on ES2.Kenneth Graunke
Hopefully should fix bug #32520.
2010-12-25intel: Only do frame throttling at glFlush time when using frontbuffer.Eric Anholt
This is the hack for input interactivity of frontbuffer rendering (like we do for backbuffer at intelDRI2Flush()) by waiting for the n-2 frame to complete before starting a new one. However, for an application doing multiple contexts or regular rebinding of a single context, this would end up lockstepping the CPU to the GPU because every unbind was considered the end of a frame. Improves WOW performance on my Ironlake by 48.8% (+/- 2.3%, n=5)
2010-12-23intel: Remove unnecessary headers.Vinson Lee
2010-12-23i965: Use MI_FLUSH_DW for blt ring flush on sandybridgeZhenyu Wang
Old MI_FLUSH command is deprecated on sandybridge blt.
2010-12-21intel: Check for unsupported texture when finishing using as a render targetChris Wilson
Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=32541 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-12-16intel: Support glCopyTexImage() from XRGB8888 to ARGB8888.Eric Anholt
The only mismatch between the two is that we have to clear the destination's alpha to 1.0. Fixes WOW performance on my Ironlake, from a few frames a second to almost playable.
2010-12-16intel: Try to sanely check that formats match for CopyTexImage.Eric Anholt
Before, we were going off of a couple of known (hopeful) matches between internalFormats and the cpp of the read buffer. Instead, we can now just look at the gl_format of the two to see if they match. We should avoid bad blits that might have been possible before, but also allow different internalFormats to work without having to enumerate each one.
2010-12-16intel: Drop commented intel_flush from copy_teximage.Eric Anholt
The blit that follows appears in the command stream so it's serialized with previous rendering. Any queued vertices in the tnl layer were already flushed up in mesa/main/.
2010-12-16intel: Update renderbuffers before looking up CopyTexImage's read buffer.Eric Anholt
Not fixing a particular bug, just noticed by code inspection.
2010-12-13i965: Add support for using the BLT ring on gen6.Eric Anholt
2010-12-13intel: Include stdbool so we can stop using GLboolean when we want to.Eric Anholt
This requires shuffling the driconf XML macros around, since they use true and false tokens expecting them to not get expanded to anything.
2010-12-10intel: Just use ChooseTextureFormat for renderbuffer format choice.Eric Anholt
One less place to forget to put your new MESA_FORMAT support in.
2010-12-10intel: Add a couple of helper functions to reduce rb code duplication.Eric Anholt
2010-12-10intel: Add spans code for the ARB_texture_rg support.Eric Anholt
This starts spantmp2.h down the path of using MESA_FORMAT_* for specifying the format instead of the crazy GL format/type combo.
2010-12-09intel: Use plain R8 and RG8 for COMPRESSED_RED and COMPRESSED_RG.Eric Anholt
Fixes texture-rg.
2010-12-06i965: Remove INTEL_DEBUG=glsl_force now that there's no brw_wm_glsl.cEric Anholt
2010-12-04intel: Add an env var override to execute for a different GPU revision.Eric Anholt
Sometimes I'm on the train and want to just read what's generated under INTEL_DEBUG=vs,wm for some code on another generation. Or, for the next gen enablement we'll want to dump aub files before we have the actual hardware. This will let us do that.
2010-11-23i915: Disallow alpha, red, RG, and sRGB as render targetsIan Romanick
Fixes bugzilla #31832 NOTE: This is a candidate for the 7.9 branch.
2010-11-20intel: Remove unnecessary header.Vinson Lee
2010-11-18mesa: pass gl_format to _mesa_init_teximage_fields()Brian Paul
This should prevent the field going unset in the future. See bug http://bugs.freedesktop.org/show_bug.cgi?id=31544 for background. Also remove unneeded calls to clear_teximage_fields(). Finally, call _mesa_set_fetch_functions() from the _mesa_init_teximage_fields() function so callers have one less thing to worry about.
2010-11-10intel: Add a new B43 pci id.Robert Hooker

2010-11-09intel: Add assert check for blitting alignment.Peter Clifton
Also fixup code comment to reflect that the GPU requires DWORD alignment, but in this case does not actually pass the value "in DWORDs" as I previously stated.
2010-11-09Revert "intel: Fix the client-side swapbuffers throttling."Eric Anholt
This reverts commit 76360d6abc9e0195bc5c373101ae616e68b2e6e6. On second thought, it turned out that sync objects also used the wait_rendering API like this, and would need the same treatment, and so wait_rendering itself is fixed in libdrm now.
2010-11-09intel: Fix the client-side swapbuffers throttling.Eric Anholt
We were asking for a wait to GTT read (all GPU rendering to it complete), instead of asking for all GPU reading from it to be complete. Prevents swapbuffers-based apps from running away with rendering, and produces a better input experience.
2010-11-08intel: Fix emit_linear_blit to use DWORD aligned width blitsPeter Clifton
The width of the 2D blits used to copy the data is defined as a 16-bit signed integer, but the pitch must be DWORD aligned. Limit to an integral number of DWORDs, (1 << 15 - 4) rather than (1 << 15 -1). Fixes corruption to data uploaded with glBufferSubData. Signed-off-by: Peter Clifton <pcjc2@cam.ac.uk>
2010-11-03intel: Remove leftover dri1 locking fields in the context.Eric Anholt
2010-11-03intel: Remove duplicated teximage miptree to object miptree promotion.Eric Anholt
intel_finalize_mipmap_tree() does this optimization too, just more aggressively.
2010-11-03intel: Avoid taking logbase2 of several things that we max.Eric Anholt
logbase2(max(width, height, depth)) == max(logbase2(width), logbase2(height), logbase2(depth)), but in 60 bytes less code.
2010-11-03intel: Remove the magic unaligned memcpy code.Eric Anholt
In testing on Ironlake, the histogram of clocks/pixel results for the system memcpy and magic unaligned memcpy show no noticeable difference (and no statistically significant difference with the 5510 samples taken, though the stddev is large due to what looks like the cache effects from the different texture sizes used).
2010-11-03intel: Annotate debug printout checks with unlikely().Eric Anholt
This provides the optimizer with hints about code hotness, which we're quite certain about for debug printouts (or, rather, while we developers often hit the checks for debug printouts, we don't care about performance while doing so).
2010-11-02intel: For batch, use GTT mapping instead of writing to a malloc and copying.Eric Anholt
No measurable performance difference on cairo-perf-trace, but simplifies the code and should have cache benefit in general.
