native_display_buffer is just a wrapper to resource_{from,get}_handle
for drm backend.
|
|
The interface is a wrapper to pipe_screen::resource_from_handle and
pipe_screen::resource_get_handle. A winsys handle is
platform-dependent.
|
|
This allows a backend to be written in C++.
|
|
Added for completeness. It makes sense to have such mechanism, but I am
not aware of any user of that..
|
|
The value of EGL_MAX_SWAP_INTERVAL and whether
EGL_SWAP_BEHAVIOR_PRESERVED_BIT is set will depend on the native
backend used.
|
|
They are deprecated by native_surface::present and there is no user of
them.
|
|
Replace native_surface::flush_frontbuffer and
native_surface::swap_buffers calls by native_surface::present calls.
|
|
The callback presents the given attachment to the native engine. It
allows the swap behavior and interval to be controlled. It will replace
native_surface::flush_frontbuffer and native_surface::swap_buffers
shortly.

Use scons target and dependency system instead of ad-hoc options.
Now is simply a matter of naming what to build. For example:
scons libgl-xlib
scons libgl-gdi
scons graw-progs
scons llvmpipe
and so on. And there is also the possibility of scepcified subdirs, e.g.
scons src/gallium/drivers
If nothing is specified then everything will be build.
There might be some rough corners over the next days. Please bare with me.

Remove all _egl<Res>IsLinked and _egl<Res>IsBound. Update
_eglBindContext and drivers to do reference counting.
|
|
Define the unit to match _EGLMode's.
|
|
Internally a mode belongs to a screen. But functions like
eglGetModeAttribMESA treat a mode as a display resource: a mode can be
looked up without a screen. Considering how KMS works, it is better to
stick to the current implementation.
To properly support looking up a mode without a screen, this commit
assigns each mode (of all screens) a unique ID.
|
|
Make _eglInitScreen take a display and rename _eglAddScreen to
_eglLinkScreen. Remove unused functions.
|
|
Mainly to rename _eglAddConfig to _eglLinkConfig, along with a few clean
ups.
|
|
Avoid code duplications.
|
|
The opaque nature of EGLImage implies that extensions almost always
define their own attributes. Move attributes in _EGLImage to
_EGLImageAttribs and add a helper function to parse attribute lists.
|
|
i915g would dereference the NULL pointer.
|
|
Drop the use of SET_CONFIG_ATTRIB. Fix the value of EGL_SAMPLE_BUFFERS
along the way.
|
|
__GLcontextModes is always only used as an implementation internal struct
at this point and we shouldn't install glcore.h anymore. Anything that
needs __GLcontextModes should just include the struct in its headers files
directly.
|
|
Fix a regression since 17eace581d25a626a7d75d9d1205d012cbb14a6e.

Let DRI2 report single-buffered configs and skip them in EGL. This is
based on the patch by Luca Barbieri.
|
|
The Gallium EGL state tracker reuses dri2.c but not the GLX code.
Currently there is a bit of code in dri2.c that is incorrectly tied
to GLX: instead, make it call an helper that both GLX and Gallium EGL
implement, like dri2InvalidateBuffers.
This avoids a link error complaining that dri2GetGlxDrawableFromXDrawableId
is undefined.
Note that we might want to move the whole event translation elsewhere,
and probably stop using non-XCB DRI2 altogether, but this seems to be
the minimal fix.

s/kms/drm/, s/kdpy/drmdpy/, and so forth.
|
|
The main use of the backend is to support EGL_MESA_drm_display. drm
should be a better name.
|
|
The modeset code supports now obsolete EGL_MESA_screen_surface. Move it
to a file of its own.
|
|
Replace all uses of ST_API_OPENGL_ES{1,2} by profiles. Having 3
st_api's to provide OpenGL, OpenGL ES 1.1, and OpenGL ES 2.0 is not a
sane abstraction, since all of them share glapi for current
context/dispatch management.
|
|
Add struct st_context_attribs to describe context profiles and
attributes. Modify st_api::create_context to take the new struct
instead of an st_visual.
st_context_attribs can be used to support GLX_ARB_create_context_profile
and GLX_EXT_create_context_es2_profile in the future. But the
motivation for doing it now is to be able to replace ST_API_OPENGL_ES1
and ST_API_OPENGL_ES2 by profiles.

It should be called DRM backend now.
|
|
When the kernel driver name is radeon, ask the loader for r300 or r600
depending on the PCI ID.
|
|
Add new source files to SConscripts.
|
|
The extension is implemented by pipe_fence_handle.
|
|
The extension is implemented by pipe_condvar.
|
|
This allows Mesa EGL to be compiled with eglext.h that does not define
EGL_MESA_screen_surface.

Mainly, the type of __GLXdisplayPrivateRec::screenConfigs has changed
from "__GLXscreenConfigs *" to "__GLXscreenConfigs **".
|
|
st/egl uses GLX code for DRI2 support. It should honor
GLX_DIRECT_RENDERING.
Also updates configure.ac to define GLX_DIRECT_RENDERING for st/egl.
|
|
|
|
The configs should be FREE()ed, not free()ed. We cannot rely on
_eglCleanupDisplay here.

The target supports OpenVG on Windows with software rasterizer. The
egl_g3d_loader defined by the target supports arbitrary client APIs and
window systems. It is the SConscript that limits the support to OpenVG
and GDI.
This commit also fixes a typo in gdi backend.
