Also fix pipe_radeon.so not building
|
|
|
|
|
|
|
|
This change makes st/egl build a single egl_gallium.so and multiple
st_<API>.so and pipe_<HW>.so. When a display is initialized, the
corresponding pipe driver will be loaded. When a context is created,
the corresponding state tracker will be loaded.
Unlike DRI drivers, no ABI compatibility is maintained. egl_gallium,
pipe drivers and state trackers should always be distributed as a single
package. As such, there is only a single src/gallium/targets/egl/ that
builds everything for the package.
|
|
Several changes are made. libegl.a no longer defines _eglMain. It
defines functions to create and destroy a _EGLDriver instead. The
creation function is called by the targets. It takes an egl_g3d_loader
as its argument. The loader is defined by the targets and is in charge
of creating st_api and pipe_screen. This allows us to move the module
loading code to targets. Lastly, the modules are now loaded as the
respective contexts are created.
|
|
Merge all targets into targets/egl/. The target produces
egl_gallium_<HW>.so for each pipe driver and st_<API>.so for each client
APIs. This enables us to further merge egl_gallium_<HW>.so into
egl_gallium.so later.
|
|
Merge multiple egl_<platform>_<pipe>.so into a single
egl_gallium_<pipe>.so. The environment variable EGL_PLATFORM is now
used to modify the return value of _eglGetNativePlatform.
|
|
This allows api_OpenGL.so to support OpenGL ES.

Well sorta, at least I removed the drm_api dependancy and the
target can layer anything it wants to now.
|
|
Currently unconditional and causes segfaults.

A platform is already used to mean a window system in EGL. No need to
use a different term.

The KMS backend requires a hardware pipe driver. Do not build
egl_kms_swrast. Also, only build egl_fbdev_swrast for fbdev backend.
It is a pure software backend.
|
|
The backend is pure software. It implements EGL_MESA_screen_surface
extension, and is kept simple by only exporting the current mode.

The EGL state tracker is really weird in how it does software,
in the past we would just not return a drm_api struct but now,
there is no callback to get a function so we just set the
create_screen hock to NULL to make it switch to software.

So something in the build keept updating the timestamp on the
staging directory causing us to always copy the library to it.

The xorg state tracker gets two new options to let the user choose
whether to enable / disable dirty throttling and swapbuffer throttling.
The default value of these options are enabled, unless the winsys
supplies a customizer with other values. The customizer record has been
extended to allow this, and also to set winsys-based throttling on a per-
context basis.
The vmware part of this patch disables the dirty throttling if the kernel
supports command submission throttling, and also in that case sets kernel
based throttling for everything but swapbuffers. The vmware winsys does not
set throttling per context, even if it theoretically could, but instead
sets throttling per screen. This should perhaps be changed, should the
xorg state tracker start to use multiple rendering contexts. Kernel throttling
is off by default for all new screens/contexts, so the dri state tracker
is not affected.
This significantly improves interactivity of the vmware xorg driver.

It will build api_OpenVG.dll on Windows.
|
|
egl_gdi_swrast uses st/egl/gdi and winsys/sw/gdi to provide an EGL
driver for Windows.
|
|
Fix several portability issues and add SConscript for Windows build.
