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.
|
|
The current context should be notified when the the front/back buffers
of the current drawable are swapped. The notification was skipped when
xmesa_strict_invalidate is false (the default).
This fixes fdo bug #29774.

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.

libmesagallium.a that this state tracker will be linked to expects
OpenGL's _glapi_table. That is, it expects libGL.so instead of
libGLESv1_CM.so or libGLESv2.so. As there is no clean way to know the
shared library the app links to, use the api as a simple check. It
might be as well to simply remove this function call though.

Make st/dri screens capable of creating OpenGL ES and
OpenGL ES2 contexts.
TODO: Figure out the "get_current" problem with multiple

Introduce a new configuration option XMESA_STRICT_INVALIDATE to switch
between swapbuffers-based and glViewport-based buffer invalidation.
Default strict invalidate to false, ie glViewport-based invalidation,
aka ST_MANAGER_BROKEN_INVALIDATE.
This means we will not call XGetGeometry after every swapbuffers,
which allows swapbuffers to remain asynchronous. For apps running at
100fps with synchronous swapping, a 10% boost is typical. For gears,
I see closer to 20% speedup.
Note that the work of copying data on swapbuffers doesn't disappear -
this change just allows the X server to execute the PutImage
asynchronously without us effectively blocked until its completion.
This applies even to llvmpipe's threaded rasterization as the
swapbuffers operation was a large part of the serial component of an
llvmpipe frame.
The downside of this is correctness - applications which don't call
glViewport on window resizes will get incorrect rendering, unless
XMESA_STRICT_INVALIDATE is set.
The ultimate solution would be to have per-frame but asynchronous
invalidation. Xcb almost looks as if it could provide this, but the
API doesn't seem to quite be there.
|
|
With this change, xmesa_get_window_size still does one round trip, but
that's better than doing two.
|
|
Try to eliminate some unnecessary X server round trips.

This is based on a patch by nobled <nobled@dreamwidth.org> and allows the TFP
extension to be enabled for DRISW also. This patch does not enable TFP for DRISW
though, because testing on xephyr segfaults here (for both classic and gallium):
Program received signal SIGSEGV, Segmentation fault.
0x00786a4a in _mesa_GenTextures (n=1, textures=0xbfffee4c) at main/texobj.c:788
788 ASSERT_OUTSIDE_BEGIN_END(ctx);

\#2 0x08168498 in __glXDispatch ()

The TFP code is generic except for the teximage call. We need to verify that
DRISW correclty implements whatever hook teximage finally calls.

It's easily reproducible with Compiz with its Resize window mode
set to Normal (which is usually not the default mode).
https://bugs.freedesktop.org/show_bug.cgi?id=28658
https://bugs.freedesktop.org/show_bug.cgi?id=29303
This is actually a workaround to prevent Compiz crashes.
Instead, a completely white titlebar might show up during resizing
transparent windows (a rare case).
The underlying cause should be fixed by someone who has more knowledge
about the code. (dri2_drawable_get_buffers should not return NULL)

This allows Mesa EGL to be compiled with eglext.h that does not define
EGL_MESA_screen_surface.
|

|
|
|

|
|
This is only compile tested.
|

Update u_draw_quad, st/vega, and st/mesa to use pipe_context::draw_vbo.
|

|
|
There seem to be a problem with this path and freeglut where
the window wont open if SWRAST_NO_PRESENT is set to true.

This makes it possible to prune modes already in pre-init.
We also keep these resources alive across server generations, and
they are implicitly closed on server exit.
