* mesa: add a couple fast-paths to fast_read_rgba_pixels_memcpy()Brian Paul2012-04-171-7/+55
| | | | | | | | | | | | Accelerates a few glReadPixels cases for WebGL. See https://bugs.freedesktop.org/show_bug.cgi?id=48545 v2: Per Jose, use bit twiddling for the swizzle case instead of ubyte arrays (it's about 44% faster). Note: This is a candidate for the 8.0 branch. Reviewed-by: José Fonseca <[email protected]>
* mesa: use _mesa_rebase_rgba_float/uint() in glReadPixels codeBrian Paul2012-03-081-0/+4
| | | | | | | | | See the comments for _mesa_rebase_rgba_float() for details. Fixes https://bugs.freedesktop.org/show_bug.cgi?id=46679 NOTE: This is a candidate for the 8.0 branch. Reviewed-by: José Fonseca <[email protected]>
* mesa: Don't disable fast path for normalized typesNeil Roberts2012-02-281-7/+15
| | | | | | | | | | | | | | | | | | Mesa has a fast path for the generic fallback when using glReadPixels for RGBA data which uses memcpy. However it was really difficult to hit this case because it would not be used if any transferOps are enabled. Any type apart from floating point or non-normalized integer types (so any of the common types) would force enabling clamping so the fast path could not be used. This patch makes it ignore clamping when determining whether to use the fast path if the data type of the buffer is an unsigned normalized type because in that case clamping will not have any effect anyway. https://bugs.freedesktop.org/show_bug.cgi?id=46631 NOTE: This is a candidate for the 8.0 branch.

* mesa: remove unused _mesa_error_check_format_type() functionBrian Paul2012-02-071-117/+0

* mesa: stop using _mesa_error_check_format_type() in glReadPixelsBrian Paul2012-02-071-2/+7
| | | | | | | | Basically the same story as the previous commit. But we were already calling _mesa_source_buffer_exists() in ReadPixels(). Yeah, we were calling it twice. Signed-off-by: Brian Paul <[email protected]>

* mesa: new _mesa_error_check_format_and_type() functionBrian Paul2012-02-071-4/+5
| | | | | | | | | | | | | | | | | | | | This replaces the _mesa_is_legal_format_and_type() function. According to the spec, some invalid format/type combinations to glDrawPixels, ReadPixels and glTexImage should generate GL_INVALID_ENUM but others should generate GL_INVALID_OPERATION. With the old function we didn't make that distinction and generated GL_INVALID_ENUM errors instead of GL_INVALID_OPERATION. The new function returns one of those errors or GL_NO_ERROR. This will also let us remove some redundant format/type checks in follow-on commit. v2: add more checks for ARB_texture_rgb10_a2ui at the top of _mesa_error_check_format_and_type() per Ian.

* mesa: Make formats.c "datatype" values match glGetTexLevelParameter return.Eric Anholt2011-11-221-2/+2
| | | | | | | | | | | | | | | | | The formats.c code's "datatype" value is "what does this value mean", i.e. unorm or snorm or float, and is the return value from the GL_TEXTURE_RED_TYPE class of queries. The depth formats were marked as GL_UNSIGNED_INT, which is what we use for integer, and not what we should be returning from the glGetTexLevelParameter. In texstore, we were inappropriately using it as an argument to _mesa_unpack_depth_span() that was expecting a value like GL_UNSIGNED_INT or GL_UNSIGNED_SHORT. Just hardcode _mesa_unpack_depth_span()'s arguments for now, though it looks like the consumers of that interface would be happier with using MESA_FORMAT. Reviewed-by: Brian Paul <[email protected]>
