egl_dri2.c:dri2_terminate() handled terminating X11 and DRM displays.
The Wayland platform implemented its own dri2_wl_terminate(), which was
nearly a copy of the common one.
To implement the EGL platform extensions, we either need to dispatch
eglTerminate per display or define a common implementation for all
platforms. This patch chooses consolidation. It removes
dri2_wl_terminate() by folding it into the common dri2_terminate().
It was necessary to invert the `if (disp->PlatformDisplay == NULL)` and
the switch statement because, unlike DRM and X11, Wayland's terminator
performed action even when EGL didn't own the native display. In the
inversion, I replaced `disp->PlatformDisplay == NULL` with
`dri2_dpy->own_device` because the two expressions are synonymous, but
the latter's meaning is clearer.

When the user calls eglGetDisplay(EGL_DEFAULT_DISPLAY), the Wayland and
DRM platforms set dri2_dpy->own_device=true. This patch makes the X11
platform do the same for consistency.

Each of the egl_dri2 platforms (except Android) prefix their function
names with "dri2", not "dri2_${platform}". This means many function
names have three separate definitions in the egl_dri2 directory: one in
each of platform_drm.c, platform_wayland.c, and platform_x11.c. For
example, each of the three files defines dri2_create_window_surface().
The name collisions make it difficult to review patches for correctness
("Is this patch hunk calling a platform_x11 function or a global
egl_dri2 function?"), complicate debugging, and confuse code navigation
tools.
For each function in platform_x11.c prefixed with 'dri2', this patch
changes its prefix to 'dri2_x11'. Likewise for platform_drm.c and
'dri2_drm'; and platform_wayland.c and 'dri2_wl'.

This extension provides a way for an application to render to multiple
surfaces with different buffer formats without having to use multiple
contexts. An EGLContext can be created without an EGLConfig by passing
EGL_NO_CONFIG_MESA. In that case there are no restrictions on the surfaces
that can be used with the context apart from that they must be using the same
EGLDisplay.
_mesa_initialze_context can now take a NULL gl_config which will mark the
context as ‘configless’. It will memset the visual to zero in that case.
Previously the i965 and i915 drivers were explicitly creating a zeroed visual
whenever 0 is passed for the EGLConfig. Mesa needs to be aware that the
context is configless because it affects the initial value to use for
glDrawBuffer. The first time the context is bound it will set the initial
value for configless contexts depending on whether the framebuffer used is
double-buffered.

A return value of -1 indicate failure to allocate the back buffer and
means we don't segfault on the way out.
|
|
|
|
|
|
| |
The _EGLSurface struct which is embedded into dri2_egl_surface also contains a
swap interval member so the other member is redundant. Nothing was using it as
far as I can tell.

The Wayland EGL platform now respects the eglSwapInterval value. The value is
clamped to either 0 or 1 because it is difficult (and probably not useful) to
sync to more than 1 redraw.
The main change is that if the swap interval is 0 then Mesa won't install a
frame callback so that eglSwapBuffers can be executed as often as necessary.
Instead it will do a sync request after the swap buffers. It will block for
sync complete event in get_back_bo instead of the frame callback. The
compositor is likely to send a release event while processing the new buffer
attach and this makes sure we will receive that before deciding whether to
allocate a new buffer.
If there are no buffers available then instead of returning with an error,
get_back_bo will now poll the compositor by repeatedly sending sync requests
every 10ms. This is a last resort and in theory this shouldn't happen because
there should be no reason for the compositor to hold on to more than three
buffers. That means whenever we attach the fourth buffer we should always get
an immediate release event which should come in with the notification for the
first sync request that we are throttled to.
When the compositor is directly scanning out from the application's buffer it
may end up holding on to three buffers. These are the one that is is currently
scanning out from, one that has been given to DRM as the next buffer to flip
to, and one that has been attached and will be given to DRM as soon as the
previous flip completes. When we attach a fourth buffer to the compositor it
should replace that third buffer so we should get a release event immediately
after that. This patch therefore also changes the number of buffer slots to 4
so that we can accomodate that situation.
If DRM eventually gets a way to cancel a pending page flip then the compositors
can be changed to only need to hold on to two buffers and this value can be
put back to 3.
This also moves the vblank configuration defines from platform_x11.c to the
common egl_dri2.h header so they can be shared by both platforms.

Consider a typical game-style main loop which might be like this:
while (1) {
draw_something();
eglSwapBuffers();
}
In this case the game is relying on eglSwapBuffers to throttle to a sensible
frame rate. Previously this game would end up using three buffers even though
it should only need two. This is because Mesa decides whether to allocate a
new buffer in get_back_bo which would be before it has tried to read any
events from the compositor so it wouldn't have seen any buffer release events
yet.
This patch just moves the block for the frame callback to get_back_bo.
Typically the compositor will send a release event immediately after one of
the attaches so if we block for the frame callback here then we can be sure to
have completed at least one roundtrip and received that release event after
attaching the previous buffer before deciding whether to allocate a new one.
dri2_swap_buffers always calls get_back_bo so even if the client doesn't
render anything we will still be sure to block to the frame callback. The code
to create the new frame callback has been moved to after this call so that we
can be sure to have cleared the previous frame callback before requesting a
new one.

This adds an extension called EGL_WL_create_wayland_buffer_from_image
which adds the following single function:
struct wl_buffer *
eglCreateWaylandBufferFromImageWL(EGLDisplay dpy, EGLImageKHR image);
The function creates a wl_buffer which shares its contents with the given
EGLImage. The expected use case for this is in a nested Wayland compositor
which is using subsurfaces to present buffers from its clients. Using this
extension it can attach the client buffers directly to the subsurface without
having to blit the contents into an intermediate buffer. The compositing can
then be done in the parent compositor.
The extension is only implemented in the Wayland EGL platform because of
course it wouldn't make sense anywhere else.

If we're not using EGL_EXT_swap_buffers_with_damage, we have to
damage the full extent. EGL operates on buffer coordinates, but
wl_surface.damage takes surface coordinates. EGL doesn't know the
buffer transformation (rotated or scaled) and can't post accurate
damage in surface coordinates. The damage event however is clipped to
the surface extents so we can just damage the maximum rectangle.
In case of EGL_EXT_swap_buffers_with_damage, the application knows
the buffer transform and is expected to pass in rectangles in
surface space.

This typically won't make a difference, since we only send the requests at
wl_display_flush() time. There might be a small race
with another thread calling wl_display_flush() after our commit request,
but before we flush the DRI driver. Moving the commit below the DRI
driver flush call looks more natural and eliminates the small race.

The EGLConfig doesn't have the rgba masks, only the rgba sizes. To

to make sure the formats really match.

All callers now use the more correct rgba mask mechanism for filtering
out mathcing DRI configs. Even if depth and buffer size match, the
color component layout can be different, or in case or ARGB8888 and
ARGB2101010 the color components can even be different sizes.
Since anything that the depth check would reject is also rejected by
the rgba mask comparison, the depth parameter is redundant and not
specific enough. We should probably have removed it when the rgba
masks argument was introduced, but better late than never.

Matching on visual depth to buffer size makes 8 bpc RGBA look similar to
10 bit RGB with 2 bit alphs - both have buffer size 32. Instead, build
the rgba masks from the visual data and use that for finding matching
DRI configs.
We need to keep the special case that allows us to match 24 bit visuals
to DRI configs with buffer size 32. We do that by creating an alpha
mask of "all the non-rgb bits" for 24 bit visuals and matching a second
time with that.

Now that libEGL has been fixed to not leak all kinds of symbols, gbm
links to its own copy of the libwayland-drm.a helper library. That means
we can't rely on comparing the addresses of a static vtable symbol in that
library to determine if a wl_buffer is a wl_drm_buffer. Instead, we
move the vtable into the wl_drm struct and use that for comparing.
