* mesa: fix SwapBytes handling in numerous placesDave Airlie2015-09-021-13/+7
| | | | | | | | | | | | | | | | | | | 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].

* DD: Refactor BlitFramebuffer.Laura Ekstrand2015-02-021-0/+3
| | | | | | | | | In preparation for glBlitNamedFramebuffer, the DD table function BlitFramebuffer needs to accept two arbitrary framebuffer objects rather than assuming ctx->ReadBuffer and ctx->DrawBuffer.

* mesa: Add _mesa_swap2_copy and _mesa_swap4_copyIago Toral Quiroga2015-01-121-2/+15
| | | | | | | | | | | | | | | | | 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 Paul2012-02-071-3/+3
| | | | | | | | | | | | | | | | | | | | 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.
