From c7853c6de126f6794946c592deed205c0ddad2d9 Mon Sep 17 00:00:00 2001
From: Olivier Fourdan <ofourdan@redhat.com>

Subject: [PATCH xserver 01/27] xwayland: Move dmabuf interface to common
glamor code
This is preliminary work for hardware accelerated rendering with the
NVIDIA driver.
The EGLStream backend can possibly also use the dmabuf interface, so
move the relevant code from the GBM specific source to the common bits.
Signed-off-by: Olivier Fourdan <ofourdan@redhat.com>
(cherry picked from commit ae225417c0a0828ffb24e11eb4b968c34692e25a)

Subject: [PATCH xserver 2/2] xwayland/eglstream: Remove stream validity
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
To avoid an EGL stream in the wrong state, if the window pixmap changed
before the stream was connected, we would still keep the pending stream
but mark it as invalid. Once the callback is received, the pending would
be simply discarded.
But all of this is actually to avoid a bug in egl-wayland, there should
not be any problem with Xwayland destroying an EGL stream while the
compositor is still using it.
With that bug now fixed in egl-wayland 1.1.7, we can safely drop all
that logic from Xwayland EGLstream backend.

- *
- * - Start processing X client events.
- * - X window receives resize event, causing us to create a new pixmap and

- * - X window receives another resize event, and again changes its current

- * window. This pixmap is known as pixmap B.
- * - Start handling events from the wayland compositor.

- * Since both pixmap A and B will have scheduled wl_display_sync events to

- *
- * - Receive pixmap A's stream callback, attach its stream to the surface of
- * the window that just orphaned it.
- * - Receive pixmap B's stream callback, fall over and fail because the
- * window's surface now incorrectly has pixmap A's stream attached to it.
- *
- * We work around this problem by keeping a pending stream associated with

- * In the scenario listed above, this should happen:
- *
- * - Begin processing X events...
- * - A window is resized, a new window pixmap is created causing us to
- * add an eglstream (known as eglstream A) waiting for its consumer
- * to finish attachment.
- * - Resize on same window happens. We invalidate the previously pending
- * stream on the old window pixmap.
- * A new window pixmap is attached to the window and another pending
- * stream is created for that new pixmap (known as eglstream B).
- * - Begin processing Wayland events...

- * - Receive callback from compositor for eglstream B, create producer.

Subject: [PATCH xserver 02/27] xwayland: move formats and modifiers functions
to common glamor code
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This is preliminary work for hardware accelerated rendering with the
NVIDIA driver.
This moves the modifiers and formats functions previously only available
to the GBM backend to the common glamor code so that it can be used by
both the GBM and EGLStream backends.

Subject: [PATCH xserver 04/27] xwayland: implement pixmap_from_buffers for the
eglstream backend
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Provides an implementation for the pixmap_from_buffers DRI3 function for
xwayland's eglstream backend. This will be used by the NVIDIA GLX driver
to pass buffers from client applications to the server. These can then
be presented using the PRESENT extension.
To hopefully make this less error-prone, we also introduce a "type"
field for this struct to distinguish between xwl_pixmaps for the new
DRI3-created pixmaps and those for the existing glamor-created pixmaps.
Additionally, the patch enables wnmd present mode with the eglstream backend.
This involves creating a wl_buffer for the provided dma-buf before importing it
into EGL and passing this to the compositor so it can be scanned out directly
if possible.
Since both backends now support this present mode, the HAS_PRESENT_FLIP flag is
no longer needed, so it can be removed.

Subject: [PATCH xserver 05/27] xwayland-eglstream: fix X11 rendering to
flipping GL / VK window
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If a window is being used for direct rendering with OpenGL or Vulkan, and is
using the flipping path for presentation, it's pixmap will be set to a dma-buf
backed pixmap created by the client-side GL driver. However, this means that
xwl_glamor_eglstream_post_damage won't work since it requires that the pixmap
has an EGLSurface that it can render to, which dma-buf backed pixmaps do not.
In this case, though, xwl_glamor_eglstream_post_damage is not necessary since
glamor will have rendered directly to the pixmap, so we can simply pass it
directly to the compositor. There's no need for the intermediate copy we
normally do in that function.
Therefore, this change adds an early-return case to post_damage for dma-buf
backed pixmaps, and removes the corresponding asserts from that function and
allow_commits.

EGLStream wl_eglstream_display_create_stream() may fail, yet Xwayland
would try to attach the buffer which may cause a fatal Wayland protocol
error raised by the compositor.
Check if the buffer creation worked, and fail gracefully otherwise (like
wayland-eglsurface does).

Also dump the backtrace which may give more information as to where the

Subject: [PATCH xserver 09/27] xwayland/glamor: Add return status to
post_damage
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If the glamor backend failed to post damage, the caller should do the
same to avoid a failure to attach the buffer to the Wayland surface.
Change the API of Xwayland's glamor backend post_damage() to return a
status so that xwl_window_post_damage() can tell whether the callee
failed.

MIME-Version: 1.0

The EGLStream backend would sometime generate GL errors trying to draw
to the framebuffer, which gives an invalid buffer, which in turn would
generate a Wayland error from the compositor which is fatal to the
client.
Check the framebuffer status and bail out early if it's not complete,
to avoid getting into trouble later.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Some functions are called "callback" whereas they are not longer
callback functions or "unref" while they no longer deal with a reference
counter anymore, which is quite confusing. Rename those functions to be
more explicit.
Also, the pending streams can be destroyed in different places, move the
common code to separate function to avoid duplicating code and help with
readability of the code.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
eglCreateStreamKHR() can fail and return EGL_NO_STREAM_KHR, in which
case there is no point in trying to create a buffer from it.
Similarly, eglCreateStreamProducerSurfaceKHR() also fail and return
EGL_NO_SURFACE, which in turn will be used in eglMakeCurrent() as
draw/read surface, and therefore would mean no draw/read buffer.
In those cases, log the error, and bail out early. That won't solve the
issue but will help with investigating the root cause of issues with
EGLStream backend.

Subject: [PATCH xserver 13/27] xwayland/eglstream: Dissociate pending stream
from window
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Previously, we would have pending streams associated with top level X11
windows, keeping temporary accounting for the pending streams before
they get fully initialized for the xwl_pixmap which would be associated
with X11 pixmaps.
If the window content changes before the stream is ready, the
corresponding pending stream would be marked as invalid and the pending
stream would be eventually removed once the stream becomes ready.
Since commit affc47452 - "xwayland: Drop the separate refcount for the
xwl_pixmap", we no longer keep a separate reference counter for the
xwl_pixmap, but rather tie it to the X11 pixmap lifespan. Yet, the
pending stream would still be associated with the X11 toplevel window.
Dissociate the pending streams from the X11 toplevel window, to keep it
tied only to the xwl_pixmap so that we can have:
- pixmap <-> xwl_pixmap
- xwl_pixmap <-> pending stream
Of course, the pending streams remain temporary and get removed as soon
as the ready callback is triggered, but the pending streams are not
linked to the X11 window anymore which can change their content, and
therefore their X11 pixmap at any time.

Subject: [PATCH xserver 14/27] xwayland/eglstream: Keep a reference to the
pixmap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Commit affc47452 - "xwayland: Drop the separate refcount for the
xwl_pixmap" removed the separate reference counter for the xwl_pixmap
which holds the EGLStream.
While that works fine for the common case, if the window's pixmap is
changed before the stream is ready, the older pixmap will be destroyed
and the xwl_pixmap along with it, even if the compositor is still using
the stream.
The code that was removed with commit affc47452 was taking care of that
by increasing the separate reference counter for the xwl_pixmap, but it
no longer the case.
As a result, we may end up with the EGL stream in the wrong state when
trying to use it, which will cascade down into all sort of issues.
To avoid the problem, increase the reference count on the pixmap when it
is marked as invalid in EGLStream's SetWindowPixmap().
This way, the xwl_pixmap and the EGLStream are kept until released by
the compositor, even when the pixmap changes before stream is ready.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Now that the pending stream is associated with the xwl_pixmap for
EGLStream and the xwl_pixmap itself is associated to the pixmap, we have
a reliable way to get to those data from any pending stream.
As a result, the list of pending streams that we keep in the EGLStream
global structure becomes useless.
So we can drop the pending stream's xwl_pixmap and also the list of
pending streams altogether, and save us a walk though that list for each
callback.

The EGL surface for the xwl_pixmap is created once the stream is ready
and valid.
If the pixmap's EGL surface fails, for whatever reason, the xwl_pixmap
will be unusable and will end up as an invalid wl_buffer.
Make sure we do not allow commits in that case and recreate the
xwl_pixmap/stream.

Use calloc() instead of malloc() like the rest of the code.
Also fix the arguments of calloc() calls to match the definition which
is calloc(size_t nmemb, size_t size).
This is a cleanup patch, no functional change.

EGLstream's post_damage() would unconditionally return success
regardless of the actual status of the eglSwapBuffers().
Yet, if eglSwapBuffers() fails, we should not post the corresponding
damage as they wouldn't match the actual content of the buffer.
Use the eglSwapBuffers() return value as the return value for
post_damage() and do not take a refrence on the pixmap if it fails.

Subject: [PATCH xserver 19/27] xwayland/eglstream: Do not always increment
pixmap refcnt on commit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Currently, the EGLstream backend would increment the pixmap refcount for
each commit, and decrease that refcount on the wl_buffer release
callback.
But that's relying on the compositor sending us a release callback for
each commit, otherwise the pixmap refcount will keep increasing and the
pixmap will be leaked.
So instead, increment the refcount on the pixmap only when we have not
received a release notification for the wl_buffer, to avoid increasing
the pixmap refcount more than once without a corresponding release
event.
This way, if the pixmap is still in use when released on the X11 side,
the EGL stream will be kept until the compositor releases it.

blitting
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The EGLstream backend's post damage function uses a shader and
glDrawArrays() to copy the data from the glamor's pixmap texture prior
to do the eglSwapBuffers().
However, glDrawArrays() can be affected by the GL state, and therefore
not reliably produce the expected copy, causing the content of the
buffer to be corrupted.
Make sure to set the ALU to GXCopy prior to call glDrawArrays() to get
the expected result.

backed pixmaps
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
As of commit 098e0f52 xwl_glamor_eglstream_allow_commits will not allow commits
if the xwl_pixmap does not have an EGLSurface. This is valid for pixmaps backed
by an EGLStream, however pixmaps backed by a dma-buf for OpenGL or Vulkan
rendering will never have an EGLSurface. Unlike EGLStream backed pixmaps,
though, glamor will render directly to the buffer that Xwayland passes to the
compositor. Hence, they don't require the intermediate copy in
xwl_glamor_eglstream_post_damage that EGLStream backed pixmaps do, so there is
no need for an EGLSurface.

Subject: [PATCH xserver 22/27] xwayland/eglstream: flush stream after
eglSwapBuffers
When eglSwapBuffers inserts a new frame into a window's stream, there may be a
delay before the state of the consumer end of the stream is updated to reflect
this. If the subsequent wl_surface_attach, wl_surface_damage, wl_surface_commit
calls are received by the compositor before then, it will (typically) re-use
the previous frame acquired from the stream instead of the latest one.
This can leave the window displaying out-of-date contents, which might never be
updated thereafter.
To fix this, after calling eglSwapBuffers, xwl_glamor_eglstream_post_damage
should call eglStreamFlushNV. This call will block until it can be guaranteed
that the state of the consumer end of the stream has been updated to reflect
that a new frame is available.

If Xwayland's EGLstream backend supports hardware acceleration with the

Add a new member to the xwl_screen that the backend can optionally set
to the preferred GLVND vendor to use.
If not set, "mesa" is assumed.

Subject: [PATCH xserver 26/27] glx: don't create implicit GLXWindow if one
already exists
If a GLXMakeCurrent request specifies an X window as its drawable,
__glXGetDrawable will implicitly create a GLXWindow for it. However,
the client may have already explicitly created a GLXWindow for that X
window. If that happens, two __glXDrawableRes resources will be added
to the window.
If the explicitly-created GLXWindow is later destroyed by the client,
DrawableGone will call FreeResourceByType on the X window, but this
will actually free the resource for the implicitly-created GLXWindow,
since that one would be at the head of the list.
Then if the X window is destroyed after that, the resource for the
explicitly-created GLXWindow will be freed. But that GLXWindow was
already destroyed above. This crashes the server when it tries to call
the destroyed GLXWindow's destructor. It also means the
implicitly-created GLXWindow would have been leaked since the
FreeResourceByType call mentioned above skips calling the destructor.
To fix this, if __glXGetDrawable is given an X window, it should check
if there is already a GLXWindow associated with it, and only create an
implicit one if there is not.

Subject: [PATCH xserver 27/27] glx: Set ContextTag for all contexts
Currently, xorgGlxMakeCurrent() would set the context tag only for
indirect GLX contexts.
However, several other places expect to find a context for the tag or
they would raise a GLXBadContextTag error, such as WaitGL() or WaitX().
Set the context tag for direct contexts as well, to avoid raising an
error and possibly killing the client and set currentClient.
