| | | | | | | | | | | | | | | | | | | In a number of places the SwapBytes handling didn't handle cases with GL_(UN)PACK_ALIGNMENT set and 7 byte width cases aligned to 8 bytes. This adds a common routine to swap bytes a 2D image and uses this code in: texture storage texture get readpixels swrast drawpixels. [airlied: updated with Brian's nitpicks].

| | | | | | | | | | Some people have complained that code using the CEILING() macro is difficult to understand because it's not immediately obvious what it is supposed to do until you go and look up its definition. Use a more descriptive name that matches the similar utility macro in the Linux kernel. Reviewed-by: Matt Turner <[email protected]>

* mesa: Add _mesa_swap2_copy and _mesa_swap4_copyIago Toral Quiroga2015-01-121-8/+17
| | | | | | | | | | | | | | | | | We have _mesa_swap{2,4} but these do in-place byte-swapping only. The new functions receive an extra parameter so we can swap bytes on a source input array and store the results in a (possibly different) destination array. This is useful to implement byte-swapping in pixel uploads, since in this case we need to swap bytes on the src data which is owned by the application so we can't do an in-place byte swap. v2: - Include compiler.h in image.h, which is necessary to build in MSCV as indicated by Brian Paul.

I believe that was already the sensible interpretation, but spelling it out is probably better. More practically, it also prevents people from accidentally copy & pasting the license into a new file which says Brian is not liable when he isn't even one of the authors.

* mesa: new _mesa_error_check_format_and_type() functionBrian Paul2012-02-071-62/+154
| | | | | | | | | | | | | | | | | | | | 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: allow exposing GL3 without EXT_texture_integerMarek Olšák2012-01-251-4/+8
| | | | | | | | | | | Strictly speaking, it's not legal to expose EXT_texture_integer without EXT_gpu_shader4. It might be even dangerous (apps can assume EXT_gpu_shader4 is available without checking for it). The check in compute_version is removed as well, because that's already covered by GLSLVersion >= 130. Reviewed-by: Brian Paul <[email protected]>

* mesa/image: assert on bad formatnobled2011-12-081-11/+9
| | | | | | | | | | | | | | | | | NULL as an error indicator is meaningless, since it will return NULL on success anyway if the caller passes in zero as the image's address and asks to calculate the offset of the first pixel. For example, _mesa_validate_pbo_access() does this. This also matches the code in the non-GL_BITMAP codepath, which already has an assert like this. v2: Per Brian Paul's review, remove the function call entirely and tighten the assert to only accept the two formats compatible with GL_BITMAP. They always have one component per pixel. Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Ian Romanick <[email protected]>

* mesa: Make _mesa_is_stencil_format() consistent with _mesa_is_depth_format().Eric Anholt2011-11-291-1/+0
| | | | | | | | | | | | | | | | | There was only one consumer of this API, meta.c, which was intending to ask "is this format just stencil index (and nothing else)?". Instead, if one tried to glDrawPixels of GL_DEPTH_STENCIL-type formats, it would just try to draw the stencil parts. Nothing good came of this. This function looks rather silly at this point, but I'm leaving it in place to be the obvious parallel API to _mesa_is_depth_format(). Note that if you want the old behavior, you should use it as (_mesa_is_stencil_format() || _mesa_is_depthstencil_format()) like is commonly done for depth-related tests.

| | | | | | | | | | | | | | | | | The encoding/decoding algorithms are shared with RGTC. Thanks to some magic with the base format, the RGTC texstore functions work for LATC too. swrast passes the related piglit tests besides two things: - The alpha channel is wrong (it's always 1), however the incorrect alpha channel makes some other tests fail too, so I guess it's unrelated to LATC. - Signed LATC fetches aren't correct yet (signed values are clamped to [0,1]), however RGTC has the same problem. Further testing (with other of my patches) shows that hardware drivers and softpipe work. BTW, ETQW uses this extension.
