2012-06-10meta: Use sampler object in framebuffer blitHEADmasterARB_sampler_objectPauli Nieminen1-17/+14
Framebuffer blit needs to setup texture sampling to match application requested blit operation. Sampler object can be used to avoid changes to texture object. But caching sampler object doesn't make much sense when we need to synamically change it based on filtering parameters. Signed-off-by: Pauli Nieminen <pauli.nieminen@linux.intel.com>
2012-06-10meta: Add sampler object to texture decompressionPauli Nieminen1-21/+24
Sampler objects can be used to shadow texture object state without modifying original application state. Decompression path feels a bit like path where caching shouldn't happen. But as everything else is cached already I decided to cache sampler state too. Signed-off-by: Pauli Nieminen <pauli.nieminen@linux.intel.com>
2012-06-10meta: texture rectangle textures may not have mipmapsPauli Nieminen1-2/+4
Avoid INVALID_OPERATION error if decompressing rectangle texture. Setting mipmap level limits for those textures is error that must not be hit by meta code to mislead user. Signed-off-by: Pauli Nieminen <pauli.nieminen@linux.intel.com>
2012-06-10meta: Use sampler object for mipmap generationPauli Nieminen1-25/+27
Sampler objects are perfect for meta operations.Sampler object is separate state object that shadows the sampling state in texture object. With sampler object mipmap can maintain same sampling state for all subsequent generation requests. Signed-off-by: Pauli Nieminen <pauli.nieminen@linux.intel.com>
2012-06-10mesa/samplerobj: Allow meta module to call sampler functionsPauli Nieminen2-4/+15
To allow meta module to use sample objects mesa GL functions need to be visible and linkable for meta module. Signed-off-by: Pauli Nieminen <pauli.nieminen@linux.intel.com>
2012-06-10swrast: Support sampler object for texture fetching statePauli Nieminen10-358/+438
swrast needs to pass sampler object into all texture fetching functions to use correct sampling state when sampler object is bound to the unit. The changes were made using half manual regular expression replace. With the patch llvmpipe didn't get any regressions. Signed-off-by: Pauli Nieminen <pauli.nieminen@linux.intel.com>
2012-06-10mesa: Make ARB_sampler_objects mandatorPauli Nieminen6-11/+3
To allow meta acceleration operations to use sampler objects the ARB_sampler_objects extension needs to be mandator for all drivers. Because the extension doesn't have any hardware dependencies it is trivial to implement. Signed-off-by: Pauli Nieminen <pauli.nieminen@linux.intel.com>

2012-06-10mesa: Check index buffer offset in DrawElementsPauli Nieminen1-1/+2
DrawElements checks for cound beeing larger than index buffer object. But application can specify offset to buffer leading to buffer overflow again. ARB_vertex_buffer_object leaves the case undefined but allows program termination. But if we do check the index buffer size it makes sense to check it correctly. " What happens when an attempt is made to access data outside the bounds of the buffer object with a command that dereferences the arrays? RESOLVED: ALLOW PROGRAM TERMINATION. In the event of a software fallback, bounds checking can become impractical. Since applications don't know the actual address of the buffer object and only provide an offset, they can't ever guarantee that out-of-bounds offsets will fall on valid memory. So it's hard to do any better than this." Signed-off-by: Pauli Nieminen <pauli.nieminen@linux.intel.com>
2012-06-10radeon&r200: Add support for ARB_shader_objectPauli Nieminen10-46/+57

2012-06-10nouveau: Add support for ARB_sampler_objectPauli Nieminen3-31/+39
ARB_sampler_object is very simple software only extension to support. I want to make it mandator extension for Mesa drivers to allow meta module to use it. This patch add support for the extension to nouveau. It is completely untested search and replace patch. I hope someone with old NV hardware could give a try that there is no regressions and ARB_sampler_object tests passes.

2012-06-10mesa/samplerobj: Avoid crash in sampler query if texture unit is disabledPauli Nieminen1-1/+3
Sampler queries are so far made only for enabled texture unit. But if any code would query sampler before checking texture unit state that would result to NULL deference. Making the inline helper easier to use with NULL check makes a lot sense because compiler is likely to combine the checks for the current texture. Signed-off-by: Pauli Nieminen <pauli.nieminen@linux.intel.com>
2012-06-10mesa/samplerobj: Support EXT_texture_sRGB_decodePauli Nieminen1-0/+56
sRGBDecode state is part of sampler object state but mesa was missing handlers to access the state. This patch adds the support for required state changes and queries. GL_EXT_texture_sRGB_decode issue 4: "4) Should we add forward-looking support for ARB_sampler_objects? RESOLVED: YES If ARB_sampler_objects exists in the implementation, the sampler objects should also include this parameter per sampler." Signed-off-by: Pauli Nieminen <pauli.nieminen@linux.intel.com>
2012-06-10mesa/macros: Add ARRAY_SIZE helper macro core mesaPauli Nieminen3-4/+4
The ARRAY_SIZE macro is usefull helper that is used already in many parts of core. But mesa core was missing it. I decided to add it to the macros.h when I wanted to use it in following patch. Signed-off-by: Pauli Nieminen <pauli.nieminen@linux.intel.com>
2012-06-10mesa: Move DepthMode to texture objectPauli Nieminen12-21/+19
GL_DEPTH_TEXTURE_MODE isn't meant to be part of sampler state based on compatibility profile specifications. OpenGL specification 4.1 compatibility 20100725 3.9.2: "... The values accepted in the pname parameter are TEXTURE_WRAP_S, TEXTURE_WRAP_T, TEXTURE_WRAP_R, TEXTURE_MIN_- FILTER, TEXTURE_MAG_FILTER, TEXTURE_BORDER_COLOR, TEXTURE_MIN_- LOD, TEXTURE_MAX_LOD, TEXTURE_LOD_BIAS, TEXTURE_COMPARE_MODE, and TEXTURE_COMPARE_FUNC. Texture state listed in table 6.25 but not listed here and in the sampler state in table 6.26 is not part of the sampler state, and remains in the texture object." Same can be found from 3.3 compatibility specification. That makes me think that moving DepthMode from sampler state makes sense to avoid bugs if DepthMode happens to be used with sampler objects.

2012-06-10mesa: Remove unnecessary parameters from AllocTextureImageBufferPauli Nieminen9-56/+29
Size and format information is always stored in gl_texture_image structure. That makes it preferable to remove duplicate information from parameters to make interface easier to understand. Signed-off-by: Pauli Nieminen <pauli.nieminen@linux.intel.com>
2012-06-10mesa: Remove unnecessary parameters from TexImagePauli Nieminen9-88/+33
gl_texture_image structure always holds size and internal format before TexImage driver hook is called. Those passing same information in function parameters only duplicates information making the interface harder to understand. Signed-off-by: Pauli Nieminen <pauli.nieminen@linux.intel.com>
2012-06-10mesa/format_unpack: Fix YCBCR unpackPauli Nieminen1-36/+66
The YCBCR unpack was reading one RGBA value from 4 bytes of YCBCR texture. But single pixel is only 2 bytes in the format. After noticing that error Ville told me that second chroma sample has to be average to match video requirements. Looking at places where unpack to rgba is called it is possible to get odd X coordinate and odd number of bytes. That makes unpack operation complex problem. But I assume that source allocation is 4 byte aligned always. That should hold for most of allocations but may fail. Better solution would be threating YCBCR as compressed format internally. But I suspect that I would break a lot of assumptions everywhere with that changes. But same time as I was checking call sites I started suspecting that we can't ever hit these unpack functions for YCBCR. But I need to study the code paths a lot more to be sure if that is true. Changes to fix unpacking: * Always start reading from the start of chroma pair. * Always read to the end of chroma pair * Unpack two RGB values in single iteration * Read next chroma pair (if available) to calculate average for second sample. * Refactor shared color space conversion code to separate function.

2012-06-07i965/blorp: allow all buffer formats provided src and dst match.Paul Berry1-25/+7
Previously, blits using the "blorp" mechanism only worked for 8-bit RGBA color buffers, 24-bit depth buffers, and 8 bit stencil buffers. This was not enough, because the blorp mechanism must be used for blitting whenever MSAA is in use. This patch allows all formats to be used, provided the source and destination formats match. So far I have confirmed that the following formats work properly with MSAA: - GL_RGB - GL_RGBA - GL_ALPHA - GL_ALPHA4 - GL_ALPHA8 - GL_R3_G3_B2 - GL_RGB4 - GL_RGB5 - GL_RGB8 - GL_RGB10 - GL_RGB12 - GL_RGB16 - GL_RGBA2 - GL_RGBA4 - GL_RGB5_A1 - GL_RGBA8 - GL_RGB10_A2 - GL_RGBA12 - GL_RGBA16 Fixes piglit tests "EXT_framebuffer_multisample/formats {2,4}" on Sandy Bridge and Ivy Bridge.

2012-06-07i965/blorp: Implement logic for additional buffer formats.Paul Berry3-7/+37
Previously the blorp engine only supported RGBA8 color buffers and 24-bit depth buffers. This patch adds support for any color buffer format that is supported as a render target, and for 16-bit and 32-bit depth buffers. This required threading the brw_context struct through into brw_blorp_surface_info::set() so that it can consult the brw->render_target_format array.

2012-06-07i965/blorp: De-virtualize brw_blorp_{mip,surface}_info::set() function.Paul Berry1-4/+4
Even though brw_blorp_surface_info is derived from brw_blorp_mip_info, this function doesn't need to be virtual, because it is never accessed through a base class pointer. Making the function non-virtual will allow it to take additional parameters in the brw_blorp_surface_info case. Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
2012-06-07i965/blorp: Refactor surface format determination.Paul Berry4-10/+10
This patch moves the responsibility for deciding on the format of the source and destination surfaces from the gen{6,7}_blorp_emit_surface_state() functions to brw_blorp_surface_info::set(), which is shared between Gen6 and Gen7. This will make it possible to add support for more surface formats without code duplication. Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>

2012-06-07mesa: Return 8 bits for GL_TEXTURE_RED_SIZE on RGTC formats.Kenneth Graunke1-4/+4
From the issues section of the GL_ARB_texture_compression_rgtc extension: 15) What should glGetTexLevelParameter return for GL_TEXTURE_GREEN_SIZE and GL_TEXTURE_BLUE_SIZE for the RGTC1 formats? What should glGetTexLevelParameter return for GL_TEXTURE_BLUE_SIZE for the RGTC2 formats? RESOLVED: Zero bits. These formats always return 0.0 for these respective components and have no bits devoted to these components. Returning 8 bits for red size of RGTC1 and the red and green sizes of RGTC2 makes sense because that's the maximum potential precision for the uncompressed texels. Thus, we need to return 8 bits for GL_TEXTURE_RED_SIZE on all RGTC formats and 8 bits for GL_TEXTURE_GREEN_SIZE on RGTC2 formats. BLUE should be 0.
