If someone's trying to build efl git with 2.5 year old EGL headers they get
a break on missing EGLImage...
We should probably consider keeping an up to date copy of the EGL headers
in efl. There may be someone out there with even older headers.
As suggested by @k-s
I'm pretty sure that this parser will easily fail. Eg. find uchar
properties but it's not r,g,b in this exact order? No color for you.
Find no uchar at all? Fail immediately even if we can handle a
no color situation just fine.
There's actually an array of 2 in gl_x11, but it appears we only use the
first 1, except in an #if 0 block.
I gather this is legacy for some reason - it sure doesn't seem to make
any sense now, so I'm chopping off all the extra array indexes.
Note: I've not changed gl_sdl - it looks like it doesn't use the context
or surface at all and they could just be removed, but I don't build that
one here and don't want to touch it.
This patch just removes the 'evas' field from the Outbuf structure.
This should have actually gone in on the previous patch but I missed
removing it :(

These variables are unused (as reported by gcc), and 'ob' is not
really needed in eng_update so remove that also.

eglGetProcAddress should be queried with dlsym unconditionally. What we
had could query it with other extended forms of eglGetProcAddress, which
is probably not what anyone wants.
Also, throwing away the weird extended forms because there's a good chance
our other gl bits don't run on any stacks that don't support normal
eglGetProcAddress.
Commit fcef8d8392
breaks any evas engine that frees/NULLs its own outbuf before
calling evas_render_engine_software_generic_update()
We should unconditionally set the outbuf, we only need to
do the free conditionally.
evas_render_engine_software_generic_update(0 definitely is wrong where
it wants to always free the outbuf even if the buffer passed in is the
same one and thus it ends up being freed and now invalid. fix it
@fix
Because we async render into buffers before the compositor has told us
we can use them, we can end up kicking over to fallback while still
rendering into a buffer.
Refcount the manager to let us clean up properly without crashing when
this happens.
If we render fast enough we can use more than one buffer before the
compositor assigns us buffer ids. We need to be careful to clear the
busy bit on all but the most recent one.
Enlightenment needs to know if a specific dmabuf format is supported
before it lets clients use it. This lets E test commit a wayland
dmabuf object without assigning it a buffer.

On an engine resize, we previously would destroy the Outbuf structure.
This patch modifies the code so that on a resize we no longer have to
destroy the old Outbuf and reallocate a new one. Instead, we will just
reconfigure the existing one and update it's properties.
Signed-off-by: Chris Michael <cp.michael@samsung.com>
On an engine resize, rather than destroy & recreate the Outbuf
structure (and the associated surface) we can just call the
eng_output_resize function (which in turn will call
outbuf_reconfigure) to update Outbuf with new properties. This saves
us from having to create a whole new Outbuf every time we resize.

In C we need this to make clear that we really do not accept parameters.
Found by the smatch source code matcher. I had run and fixed this before
but it seems to creep in again over time.
Using *im and dereferencing it before doing the actual NULL check does not make
much sense. I kept the checks as they have been there before so the intent was
probably that they could be NULL and should be checked.

If the hidden flag is set, then we don't need to recreate the Outbuf
for a given canvas as the window is hidden and we are not going to
render there until it's shown again.

When a canvas gets hidden, we don't need to destroy & recreate the
wl_surface. We can simply attach a NULL wl_buffer to the surface which
achieves the same result. This saves us from having to always destroy
& recreate surfaces when we hide/show.

Software rendered wayland clients will now attempt
to use dmabuf on some platforms. This results in a window
that a compositor may be able to drop into a plane without a copy.
Disable it with the env var EVAS_WAYLAND_SHM_DISABLE_DMABUF
but if you need to disable it, please ping me or file a bug report.
Thank you NVIDIA for breaking your drivers regularly!
eglGetDisplay(x11_display) should work but was consistently
returning 0 instead.
Apparently EGL 1.5 introduced "eglGetPlatformDisplay" that
is more advanced to open a display. So, prefer that over
eglGetDisplay if it's available.
@fix
when the DIB header is BITMAPINFOHEADER (size 40),
a bitmap file has alpha channel only if the compression method is BI_ALPHABITFIELDS (= 6).
the original code enabled alpha channel when the compression method was BI_RGB (= 0),
which made an opaque bmp image loaded as a transparent one.
@fix
Not providing a call to the first method segfaults in elm_glview
right away. Instead of crashing, we now just issue a runtime error
about the method not being implemented.
If there's a "next" buffer set, we're better off freeing it before we
start to render. This lets us keep gbm from allocating an extra buffer
which it currently never frees.
Previously we'd call this only when we absolutely needed to, so it made
sense to always attempt to free a buffer, including ones on scanout or
pending flip.
However, it's useful to have a way to release the "next" only, so we can
do that before starting a render to free up the buffer that's never going
to be scanned out.
for gl noscale buffers are texture atlases that are fbo's. the point
is never to scale or transofmr them but to render them pixel for pixel
and just store pre-rendered data where its cheaper to do this than
rebuild every time. this is the enigne infra for sw and gl with the gl
code... it SHOULD work... in theory...
preparing an object is a good idea. especially with gl. you want to do
texture uploads BEFORE using textures all in one batch. otherwise this
may mean the gl implementation has to make a copy of your data in a
tmp location then copy it in later when texture becomes "unused" as it
may be in use at the moment, or it may have to stall and wait.
i have seen somewhere around 7-10% speedups on nvidia and intel
drivers with this on given a very special test case i brewed up (1000
32x32 images where i change 1 pixel every frame). this should have
impact really when we are modifying textures a lot. this is all i've
implemented for now, but this should/would/could do much more like
re-order map, proxy renders to render FIRST in a pre-render list
instead of inline and to pre-render fbo/buffer content for complex
objects like text or textblock etc.
this will define EGL_WAYLAND_PLANE_WL and EGL_WAYLAND_BUFFER_WL if
missing as SOME older egl public headers dont expose them and yet we
still wans to compile and support the feature should the egl BINARY
etc. actually support this (or be upgraded to support it after efl
compilation).
@fix
this technically isn't needed. it does help in some cases hide driver
or other buffer swap bugs, but in and of itself is not needed, so
remove. at least the drm egl bugs still happen on my pi3 so its
something else...
so i was just about to add buffer age debugging evlogs to everywhere
doing buffer age and i found... drm gl and wayland gl engines DONT
HANDLE age change like gl_x11! they dont reset to a "full render" for
that frame. well well. this explains bugs i am seeing for sure. very
very bag! i thought this was handled properly. this does lend some
credence to my thoughts about somehow having a single universal buffer
swapping/update calculating and "applying" api inside efl somewhere...
anyway - this fixes this issue for these 2 engines which is a real
necessary fix to be correct.
@fix
The first patch did not work for maps. This explains why the
original code was so weird. But it actually made sense.
After struggling a bit I realized that we really just need
to shuffle around the pixel position on the window to map that
of the position in the canvas (unrotate it).
Note that compatibility with GLSL-ES (for OpenGL ES) implies
we can not use an array initializer like:
vec2 pos[4] = vec2[4](a,b,c,d);
So the code could probably be optimized. But at least this works.
This patch also avoids calling glGetUniformLocation again and
again.
as per mailing list discussion about dropping xcb support now. it
hasn't been complete for a long time, thus not recommented for being
turned on. as we are moving to a wayland world xcbmakes even less
sense. as agreed, time to clean up a bit and remove a distraction as
well as not well tested code. this also updates po's too.
@feature
The original solution was really complex and relied on
transforming the current gl_Position into the screen
coordinate in pixels, and map that to the pixel position
in the mask.
This new solution simply pushes the required vertices for
the mask, based on its geometry. This fixes masks when used
in a rotated window.
Why was it so hard to get right? :(
@fix
These engines are incredibly similar - by sharing the same engine info
structure we'll be able to simplify the wayland ecore_evas bits and
make them much more maintainable.
In the event that an ecore_evas (using wayland_shm) gets hidden then
the corresponding wl_surface gets destroyed. If evas_norender is
called after that, the outbuf_redraws_clear function follows.
Outbuf_redraw_clear function ends up trying to post updates to the
wl_surface however if that wl_surface is gone, then we end up crashing.
This patch addresses that issue by checking for a valid wl_surface
inside the engine before trying to post updates to that wl_surface.

Now that we have redraws_clear exposed through software generic, we can
use that to do the final buffer swap from the main thread instead of doing
it in outbuf_flush which runs from the render thread.
This becomes more important later when other call sites in the main thread
will perform buffer flips.

When triple buffering it's possible that we'll only need two buffers at
a time for long durations. When we finally call upon a third buffer it
hasn't been used recently enough to do a partial redraw.
By picking the oldest available buffer when multiple buffers are free we
can increase the likelihood of doing partial redraws.

One deadlock and one segfault.
Patch 1:
Software X11 Evas Engine: Fix deadlock
Summary:
The patch bc6e8d2692 introduced a callback responsible to notify the pixels
that were sent to the X server. Since all EFL rendering is done by another
thread, the callback should be called from the main thread context.
To achieve this behaviour evas_software_x11_region_push_hook_call()
was using ecore_thread_main_loop_begin(), which may cause deadlocks, since
evas mainloop waits for the render thread and the render thread waits
the mainloop.
In order to fix this problem, the function
ecore_main_loop_thread_safe_call_async() will be used to
schedule the callback to run in the main loop context.
Since a callback is schedule to run in async manner, the pixels that
were sent to the X server must not be deleted until the user is informed.
In order to avoid more mallocs(), this patch adds the support for refcounts to the
X_Output_Buffer and Xcb_Output_Buffer.
Patch 2:
Ecore_Evas VNC: Use the image size to create the buffer.
In same cases they may differ and may lead to a segfault, since
memcpy() causes a buffer overrun.

KHR partial damage must be set once at the beginning of rendering with
buffer damage for the entire scene to be rendered. Doing otherwise can
result in graphical anomalies on some GL implementations.
