* mesa: clamp colors to [0,1] for glGetTexImage() when format is GL_LUMINANCEBrian Paul2009-04-031-4/+6
| | | | For luminance, we add R+G+B and it seems we should always clamp in case.
* mesa: whitespace and comment clean-upBrian Paul2009-04-031-11/+16

* mesa: in mesa_add_named_constant(), avoid adding duplicate constantsBrian Paul2009-04-031-7/+12
|
* mesa: fix parameter counting in ARB vertex/fragment program parsingBrian Paul2009-04-031-5/+2
| | | | Duplicated unnamed constants were getting counted more than once.
* mesa: replace >= with > when testing if we've exceeded max local paramsBrian Paul2009-04-031-2/+2
| | | | Now a program that uses 256 locals works as it should.
* mesa: only clear matrix MAT_DIRTY_INVERSE flag when we actually compute the ↵Brian Paul2009-04-031-3/+2
| | | | | | | | inverse If _math_matrix_analyse() got called before we allocated the inverse matrix array we could lose the flag indicating that we needed to compute the inverse. This could happen with certain vertex shader cases.
* mesa: for OPCODE_LIT, use _mesa_pow() instead of exp() and log()Brian Paul2009-04-031-2/+2
| | | | Also, s/pow/_mesa_pow/
* mesa: rename some gl_light fields to be clearerBrian Paul2009-04-0310-36/+36
| | | | | EyeDirection -> SpotDirection _NormDirection -> _NormSpotDirection
* mesa: don't normalize spot light direction until validation timeBrian Paul2009-04-031-2/+7
| | | | | In glLight() we're only supposed to transform the direction by the modelview matrix, not normalized it too.

* i965: another checkpoint commit of new constant buffer supportBrian Paul2009-04-032-65/+115
| | | | | Everything is in place now for using a true constant buffer for GLSL fragment shaders. Still some bugs to find though.
* i965: fix response length param in brw_dp_READ_4()Brian Paul2009-04-031-1/+1
| | | | We were accidentally clobbering the next register.
* i965: change args to get_src_reg() to prep for new constant buffer supportBrian Paul2009-04-031-79/+85

* i965: check-point commit of new constant buffer supportBrian Paul2009-04-035-35/+288
| | | | | | | | | | | | | | | | Currently, shader constants are stored in the GRF (loaded from the CURBE prior to shader execution). This severly limits the number of constants and temps that we can support. This new code will support (practically) unlimited size constant buffers and free up registers in the GRF. We allocate a new buffer object for the constants and read them with "Read" messages/instructions. When only a small number of constants are used, we can still use the old method. The code works for fragment shaders only (and is actually disabled) for now. Need to do the same thing for vertex shaders and need to add the necessary code-gen to fetch the constants which are referenced by the shader instructions.

* i965: code to setup a constant buffer samplerBrian Paul2009-04-031-0/+43
| | | | | This code won't actually be used and will be removed in a subsequent commit. Just committing for posterity.
* i965: do negation and Abs in get_src_reg_imm()Brian Paul2009-04-031-1/+6
| | | | Fixes regression seen with progs/glsl/bump.c

* i965: added new brw_dp_READ_4() functionBrian Paul2009-04-032-0/+57

* mesa: fix TexParameter functionsRoland Scheidegger2009-04-021-62/+86
| | | | | | | | | premature return in TexParameterf caused mesa to never call Driver.TexParameter breaking drivers relying on this (fix bug #20966). While here, also fix using ctx->ErrorValue when deciding to call Driver.TexParameter. Errors are sticky and uncleared errors thus would cause this to no longer get called. Since we thus need return value of set_tex_parameter[if] can also optimize this to only call when value changed.

* dri glx: Fix dri_util::driBindContextThomas Hellstrom2009-04-021-18/+14
| | | | | | | | | | | 1) Don't error-check here. It's done in glx makeCurrent. 2) Allow ctx and the dri drawables to be NULL for future use. This is currently blocked in glx makeCurrent. 3) Avoid updating dri drawables unless they are completely uninitialized. Since the updating was done outside of the lock, the driver need to verify and redo it anyway. Signed-off-by: Thomas Hellstrom <thellstrom-at-vmware-dot-com>
