2018-03-05glamor: Implement PixmapFromBuffers and BuffersFromPixmapLouis-Francis Ratté-Boulianne1-0/+1
It relies on GBM >= 17.1.0 where we can import BO with multiple planes and a format modifier (GBM_BO_IMPORT_FD_MODIFIER). v2: Properly free fds in Xwayland [Also add glamor_egl_ext.h to Makefile.am for distcheck's sake - ajax] Signed-off-by: Louis-Francis Ratté-Boulianne <lfrb@collabora.com> Reviewed-by: Daniel Stone <daniels@collabora.com> Acked-by: Keith Packard <keithp@keithp.com> Reviewed-by: Adam Jackson <ajax@redhat.com>
2016-10-05glamor: Use eglGetPlatformDisplay{,EXT} if we canAdam Jackson1-1/+3
eglGetDisplay forces the implementation to guess which kind of display it's been handed. glvnd does something different from Mesa, and in general it's impossible for the library to get this right. Add a new inline that gets the logic right, and works around a quirk in epoxy. Signed-off-by: Adam Jackson <ajax@redhat.com> Reviewed-by: Eric Anholt <eric@anholt.net>

2015-05-14glamor: Replace CompositeGlyphs code [v2]Keith Packard1-1/+1
New composite glyphs code uses the updated glamor program infrastructure to create efficient shaders for drawing render text. Glyphs are cached in two atlases (one 8-bit, one 32-bit) in a simple linear fashion. When the atlas fills, it is discarded and a new one constructed. v2: Eric Anholt changed the non-GLSL 130 path to use quads instead of two triangles for a significant performance improvement on hardware with quads. Someone can fix the GLES quads emulation if they want to make it faster there. v3: Eric found more dead code to delete Signed-off-by: Keith Packard <keithp@keithp.com> Reviewed-by: Eric Anholt <eric@anholt.net>

2014-06-15glamor: Add glamor_program based 0-width dashed linesKeith Packard1-0/+1
This makes sure the pixelization for dashed lines matches non-dashed lines, while also speeding them up. v2: Switch to glamor_make_current v3: Create dash pattern pixmap without GLAMOR_CREATE_FBO_NO_FBO v4: Adopt suggestions from Eric's review: - Drops power-of-two alignment of our line vertex data, simplifying the code. - Stops reading from the VBO. While on keithp's and my machines the VBO is mapped cached, on many implementations it will be mapped WC, making those reads extremely expensive. - Style fixes (line wrapping, spaces around operators). v5: Adopt suggestions from Markus' review: - Use max when computing zero-width dashed line length. Don't open code max here. - Embed CoordModePrevious into VBO writing for dashed lines Instead of pre-computing the coord mode previous results, just embed this in the loop which fills the vertex buffer. Saves re-writing the request buffer, and shortens the code a bit v6: Export glamor_destroy_gc for UXA UXA needs to call glamor_destroy_gc from its GCFuncs, so export it.

2014-06-15glamor: Add glamor_program based copy accelerationKeith Packard1-3/+1
Paints with textures, using a temporary buffer for overlapping copies Performs CPU to GPU transfers for pixmaps in memory. Accelerates copy plane when both objects are in the GPU. Includes copy_window acceleration too. v2: Use NV_texture_barrier for non-overlapping copies within the same drawable v3: Switch to glamor_make_current v4: Do overlap check on the bounding box of the region rather than on individual boxes v5: Use Eric Anholt's re-written comments which provide a more accurate description of the code v6: Use floating point uniform for copy plane bit multiplier. This avoids an int to float conversion in the copy plane fragment shader. Use round() instead of adding 0.5 in copy plane. round() and +0.5 end up generating equivalent code, and performance measurements confirm that they are the same speed. Round() is a bit clearer though, so we'll use it. Signed-off-by: Keith Packard <keithp@keithp.com> Reviewed-by: Eric Anholt <eric@anholt.net> Reviewed-by: Markus Wick <markus@selfnet.de>
2014-06-15glamor: Replace fallback preparation codeKeith Packard1-0/+2
These offer a simpler and more efficient means for temporarily transitioning to CPU-accessible memory for fallback implementations. v2: Do not attempt fallbacks with GLAMOR_DRM_ONLY pixmaps glamor cannot transfer pixels for GLAMOR_DRM_ONLY pixmaps using glReadPixels and glTexSubImage2D, and so there's no way to perform fallback operations with these pixmaps. v3: Clear ->pbo field when deleting the PBO. Otherwise, we'd reuse the old name next time we fall back on the pixmap, which would potentially conflict with some other pixmap that genned a new name, or just do a lazy allocation of the name (compat GL context, like we currently use) or error out (core GL context, like we hope to use some day).

2013-12-18GLX: Enable glx support.Zhigang Gong1-2/+2
If we are using MESA as our GL library, then both xserver's GLX and glamor are link to the same library. As xserver's GLX has its own _glapi_get/set_context/dispatch etc, and it is a simplified version derived from mesa thus is not sufficient for mesa/egl's dri loader which is used by glamor. Then if glx module is loaded before glamoregl module, the initialization of mesa/egl/opengl will not be correct, and will fail at a very early stage, most likely fail to map the element buffer. Two methodis to fix this problem, first is to modify the xserver's glx's glapi.c to fit mesa's requirement. The second is to put a glamor.conf as below, to the system's xorg.conf path. Section "Module" Load "glamoregl" EndSection Then glamor will be loaded firstly, and the mesa's libglapi.so will be used. As current xserver's dispatch table is the same as mesa's, then the glx's dri loader can work without problem. We took the second method as it don't need any change to xorg.:) Although this is not a graceful implementation as it depends on the xserver's dispatch table and the mesa's dispatch table is the same and the context set and get is using the same method. Anyway it works. As by default, xserver will enable GLX_USE_TLS. But mesa will not enable it, you may need to enable that when build mesa. Three pre-requirements to make this glamor version work: 0. Make sure xserver has commit 66e603, if not please pull the latest master branch. 1. Rebuild mesa by enable GLX_USE_TLS. 2. Put the glamor.conf to your system's xorg.conf path and make sure it loaded prior to glx module. Preliminary testing shows indirect glxgears works fine. If user want to use GLES2 for glamor by using MESA, GLX will not work correctly. If you are not using normal MESA, for example PVR's private GLES implementation, then it should be ok to use GLES2 glamor and the GLX should work as expected. In this commit, I use gbm to check whether we are using MESA or non-mesa. Maybe not the best way. Signed-off-by: Zhigang Gong <zhigang.gong@linux.intel.com>

This is the first patch to implement a fbo/tex pool mechanism which is like the sna's BO cache list. We firstly need to decopule the fbo/tex from each pixmap.
