2009-05-11mesa: better handling/printing of driver-specific opcodes, register filesBrian Paul
Drivers such as i965 define extra instruction opcodes and register files. Improve the program printing code to handle those opcodes/files better.
2009-05-08i965: improve debug loggingRobert Ellison
Looking for memory leaks that were causing crashes in my environment in a situation where valgrind would not work, I ended up improving the i965 debug traces so I could better see where the memory was being allocated and where it was going, in the regions and miptrees code, and in the state caches. These traces were specific enough that external scripts could determine what elements were not being released, and where the memory leaks were. I also ended up creating my own backtrace code in intel_regions.c, to determine exactly where regions were being allocated and for what, since valgrind wasn't working. Because it was useful, I left it in, but disabled and compiled out. It can be activated by changing a flag at the top of the file.
2009-05-08i965: fix memory leak in context/renderbuffer region managementRobert Ellison
A temporary change to the intelMakeCurrent() function to make it work with frame buffer objects causes the static regions associated with the context (the front_region, back_region, and depth_region) to take on an additional reference, with no corresponding release. This causes a memory leak if a program repeatedly creates and destroys contexts. The fix is the corresponding hack, to unreference these regions when the context is deleted, but only if the framebuffer objects are still present and the same regions are still referenced within. Both sets of code have comment blocks referring to each other.
2009-05-08i965: fix segfault on low memory conditionsRobert Ellison
When out of memory (in at least one case, triggered by a longrunning memory leak), this code will segfault and crash. By checking for the out-of-memory condition, the system can continue, and will report the out-of-memory error later, a much preferable outcome.
2009-05-08mesa: Fixed a texture memory leakRobert Ellison
The current texture for any particular texture unit is given an additional reference in update_texture_state(); but if the context is closed before that texture can be released (which is quite frequent in normal use, unless a program unbinds and deletes the texture and renders without it to force a call to update_texture_state(), the memory is lost. This affects general Mesa; but the i965 is particularly affected because it allocates a considerable amount of additional memory for each allocated texture.
2009-05-08intel: Add a metaops version of glGenerateMipmapEXT/SGIS_generate_mipmaps.Eric Anholt
In addition to being HW accelerated, it avoids the incorrect (black) rendering of the mipmaps that SW was doing in fbo-generatemipmap. Improves the performance of the mipmap generation and drawing in fbo-generatemipmap by 30%.
2009-05-08intel: Put the constant texcoords used in metaops into a vbo.Eric Anholt
Make this be its own function for setup/teardown of the binding of these texcoords. No performance difference in the engine demo (I just felt dirty not using a VBO for this), and I think it should be more resilient to interference from current GL state.
2009-05-08i965: const qualifiersBrian Paul
2009-05-08mesa: raise MAX_VARYING (number of shader varying vars) to 16Brian Paul
16 is the limit for now because of various 32-bit bitfields.
2009-05-08mesa: assertions to check for too many vertex outputs or fragment inputsBrian Paul
2009-05-08glsl: check number of varying variables against the limitBrian Paul
Link fails if too many varying vars.
2009-05-08mesa: issue warning for out of bounds array indexesBrian Paul
2009-05-08i965: don't use GRF regs 126,127 for WM programsBrian Paul
They seem to be used for something else and using them for shader temps seems to lead to GPU lock-ups. Call _mesa_warning() when we run out of temps. Also, clean up some debug code.
2009-05-08glsl: set vertex/fragment program Ids to aid with debuggingBrian Paul
2009-05-08mesa: more shader debug code (disabled)Brian Paul
2009-05-08mesa/st: keep surface_copy arguments positiveKeith Whitwell
The src/dest x,y, and w,h arguments of the pipe->surface_copy function are unsigned and the drivers aren't expecting negative (or extremly-large unsigned) values as inputs. Trim the requests at the state-tracker level before passing down.
2009-05-08mesa/st: remove redundant call to st_finish in CopyTexSubImageKeith Whitwell
Rendering should already have been flushed, any synchronization will be done by the driver or memory manager.
2009-05-08mesa/st: cope with non-ibo index data in st_draw_feedback.cKeith Whitwell
Previously only non-indexed or indicies-in-a-vbo cases were handled in this code. This change adds the missing regular indices-in-memory case.
2009-05-08mesa: Make _mesa_share_state thread safe.José Fonseca
2009-05-07mesa: make the array object save/remove functions staticBrian Paul
2009-05-07mesa: clean-up vertex array object VBO unbinding and delete/refcountingBrian Paul
Don't really delete vertex array objects until the refcount hits zero. At that time, unbind any pointers to VBOs.
2009-05-07mesa: reference counting for gl_array_objectBrian Paul
Every kind of object that can be shared by multiple contexts should be refcounted.
2009-05-07mesa: array object commentsBrian Paul
2009-05-07mesa: move the NullBufferObj from GLcontext to gl_shared_stateBrian Paul
Since shared array objects may point to the null/default buffer object, the null/default buffer object should be part of the shared state.
2009-05-07mesa: fix comments, s/texture/buffer/Brian Paul
2009-05-07vbo: in glDraw[Range]Element() code, check for out of bounds indexesBrian Paul
No-op the bad drawing command rather than go out of bounds and render garbage. Print a warning to alert the developer to the bad drawing call.
2009-05-07mesa: remove unused gl_buffer_object::OnCard fieldBrian Paul
2009-05-07mesa: added gl_buffer_object::Written flag (for debug purposes)Brian Paul
The flag is set when we data has been written into the buffer object.
2009-05-07mesa: Compute gl_client_array->_MaxElement during array validationBrian Paul
Used to be done in the glVertex/Normal/Color/etc/Pointer() calls but if the VBO was reallocated the size could change. New _NEW_BUFFER_OBJECT state flag.
2009-05-07mesa: GLvector4f:: flags is a GLbitfield, update comments too.Brian Paul
2009-05-07mesa: add storage_count field to GLvector4f. Useful for debugging.Brian Paul
2009-05-07mesa: use array->BufferObj instead of ctx->Array.ArrayBufferObjBrian Paul
No difference, but a little more understandable.
2009-05-07mesa: added _ElementSize field to gl_client_arrayBrian Paul
Will be handy for bounds checking later...
2009-05-07mesa: use local var to make code a bit more conciseBrian Paul
2009-05-07mesa: fix/add commentsBrian Paul
2009-05-07mesa: use _mesa_sizeof_type() in vbo split codeBrian Paul
2009-05-07mesa: vbo code reformatting, clean-up, commentsBrian Paul
2009-05-07mesa: add GL_DOUBLE case in _mesa_sizeof_type()Brian Paul
2009-05-07mesa: in vbo split code, map buffers read-only, not write-onlyBrian Paul
And use GL_ELEMENT_ARRAY_BUFFER where appropriate.
2009-05-07mesa: limit number of error raised by invalid GL_TEXTURE_MAX_ANISOTROPY_EXTBrian Paul
2009-05-07 tnl: added some clip debug/print code (disabled)Brian Paul
2009-05-07mesa: reformatting, updated comments, const-correctnessBrian Paul
2009-05-07tnl: replace 0x3f with CILP_FRUSTUM_BITSBrian Paul
2009-05-07i965: relAddr local var (to make debug/test a little easier)Brian Paul
2009-05-07Merge branch 'mesa_7_5_branch'Brian Paul
2009-05-07swrast: fix span clipping bugBrian Paul
If a horizontal span of pixels was located at x < 0 we could sometimes read/write outside of renderbuffer bounds.
2009-05-07mesa: unmap buffer objects during context tear-downBrian Paul
2009-05-06i965: Remove bad constant buffer constant-reg-already-loaded optimization.Eric Anholt
Thanks to branching, the state of c->current_const[i].index at the point of emitting constant loads for this instruction may not match the actual constant currently loaded in the reg at runtime. Fixes a regression in my GLSL program for idr's class since b58b3a786aa38dcc9d72144c2cc691151e46e3d5.
2009-05-06intel: Unmap buffers if needed at DeleteBuffer time.Eric Anholt
This fixes a crash in glean's pbo test, which tripped over the assert when a context was destroyed while a buffer was still mapped (Mesa doesn't call UnmapBuffer in that case). Regression in c6bde8873fbda6d8467600b7491d8543c75b0509
2009-05-06mesa: remove unnecessary buffer size checkBrian Paul
