* mesa: GL_MESA_framebuffer_flip_y extension [v4]Fritz Koenig2018-07-271-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Adds an extension to glFramebufferParameteri that will specify if the framebuffer is vertically flipped. Historically system framebuffers are vertically flipped and user framebuffers are not. Checking to see the state was done by looking at the name field. This adds an explicit field. v2: * updated spec language [for chadv] * correctly specifying ES 3.1 [for chadv] * refactor access to rb->Name [for jason] * handle GetFramebufferParameteriv [for chadv] v3: * correct _mesa_GetMultisamplefv [for kusmabite] v4: * update spec language [for chadv] * s/GLboolean/bool/g [for chadv] * s/InvertedY/FlipY/g [for chadv] * s/inverted_y/flip_y/g [for chadv] * assert changes [for chadv] Reviewed-by: Chad Versace <[email protected]>
* mesa: stop passing state bitfield to UpdateState()Timothy Arceri2017-06-091-4/+0
| | | | | | | | | | | | | | | | | | The code comment which seems to have been added in cab974cf6c2db (from year 2000) says: "Set ctx->NewState to zero to avoid recursion if Driver.UpdateState() has to call FLUSH_VERTICES(). (fixed?)" As far as I can tell nothing in any of the UpdateState() calls should cause it to be called recursively. V2: add a wrapper around the osmesa update function so it can still be used internally.

* tree-wide: remove trailing backslashEric Engestrom2017-06-071-1/+1
| | | | | | | | | Simple search for a backslash followed by two newlines. If one of the newlines were to be removed, this would cause issues, so let's just remove these trailing backslashes. Signed-off-by: Eric Engestrom <[email protected]> Reviewed-by: Ian Romanick <[email protected]>
* xlib: fix memory leak of and remove vishandle from XMesaVisualInfoJohn Sheu2016-04-151-1/+0
| | | | | | | | | | | | | | The vishandle member of XMesaVisualInfo is used to support the comparison of XVisualInfo instances by pointer value, in find_glx_visual(). The comparison however will always be false, as in every case the comparison is made, the VisualInfo instance being compared to is a new allocation passed in through a GLX API call. In addition, the XVisualInfo instance pointed to by vishandle is itself never freed, causing a memory leak. Since vishandle is essentially useless, we just remove it and thereby also fix the leak.

* mesa: Change "BRIAN PAUL" to "THE AUTHORS" in license text.Kenneth Graunke2013-04-231-1/+1
| | | | | | | | | | | | | | | | Generated automatically be the following shell command: $ git grep 'BRIAN PAUL BE LIABLE' | sed 's/:.*$//g' | xargs -I '{}' \ sed -i 's/BRIAN PAUL/THE AUTHORS/' {} The intention here is to protect all authors, not just 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.

* xmesa: drop glide (FX) backend.George Sapountzis2007-04-191-18/+1
| | | | | | glide is no longer compiled with stand-alone libGL, so this will not link. There are still the glide config files. some code in demos and the GLX_MESA_set_3dfx_mode code which could be removed.
* xmesa: export xmesa functions used by xfree86.George Sapountzis2007-04-131-10/+0
| | | | | | | | | This uses xmesa.h as the GLcore interface and avoids adding an explicit GLcore inteface which would not be a proper interface anyway. It puts the declarations of the three functions specific for XMesa/XFree86 in xmesa.h, we can push them down to xmesa_xf86.h if hiding behind XFree86Server ifdef's is not enough.
* xmesa: use newly added xm_image.[hc]George Sapountzis2007-04-061-5/+3
| | | | | | | | | Keep external includes to glxheader.h and xmesa includes to xmesaP.h. Drop the following from xm_image.h: - dix-config.h (comes from glheader.h) - xfree86 includes (come from GL/xmesa_xf86.h) - ifdef __CYGWIN__ (leftover ? xm_api.c has something similar)

* Clean and update XMesa/XFree86 interface.George Sapountzis2007-03-301-2/+3
| | | | | | | | | | | | | | | | Drop XMesaSetVisualDisplay(), XMesaReset(), no longer used. Add XMesaCopyContext() and move the GlxSetRenderTables() call for XGL within XMesaForceCurrent(). This is to make xserver/GL/mesa/X/xf86glx.c unaware of Mesa internals. Also, clean some ifdef's to make it clear that USE_XSHM and XFree86Server are mutually exclusive. Lastly, - move gcstruct.h from glxheader.h up to xmesa_xf86.h since it calls *gc->ops - drop GL/glxtokens.h from xm_api|dd.c, GLX tokens come from glcore.h and are used irrelevant of XFree86.
* Implement alpha buffer copy for SwapBuffers().Brian2007-03-231-0/+1
| | | | | | | | | | | | | Nicolai writes: When the pixmap pixel format has no alpha channel, the x11 driver (software rendering) adds a wrapped alpha channel on request. During SwapBuffers, this alpha channel is not copied from back to front, which means that the front buffer doesn't really contain the contents that the back buffer previously contained. A subsequent glReadPixels from the front buffer will return an incorrect result. The following patch attempts to fix this.
* Rewrite code related to buffer destruction.Brian2007-02-261-0/+7

| | | | | | | All buffer resizes now handled by xmesa_check_and_update_buffer_size() which uses the _mesa_resize_framebuffer() function. Moved all low-level XImage/Pixmap resizing into xm_buffers.c file. Also, update lots of comments for Doxygen.
