Emil Velikov 52a2a052aa glamor_egl: use LogMessage over xf86DrvMsg
Much of glamor already use LogMessage() so we might as well be
consistent. This effectively paves the way of making glamor-egl xf86
agnostic.

Olivier Fourdan 26fe29f4fa glamor: Make pixmap exportable from `gbm_bo_from_pixmap()`
If a pixmap is not exportable, `glamor_gbm_bo_from_pixmap()` would fail
and the modesettings driver would consequently fail to do its page flip,
which both prevents Present from working and also fill up the logs with
error messages such as:

  (EE) modeset(0): Failed to get GBM bo for flip to new front.
  (EE) modeset(0): present flip failed

Refactor the code so that `glamor_gbm_bo_from_pixmap()` takes care of
making the pixmap exportable.

Adam Jackson 766bf01b21 glamor: Fix more fallback paths with non-GXcopy rop with GLES
Desktop GL can handle arbitrary rops here, GLES can't. The switch
statement attempts to optimize some cases that GLES can still handle if
we precompute the right pixel value, but we were then throwing that
pixel value away and using gc->fgPixel anyway. Fix this, and now
xts-render passes against glamor+gles.

Eric Anholt 8702c938b3 glamor: Introduce a central place for our pixmap format/type handling.
We had various helper functions trying to come up with the
internalformat/format/type/render formats for pixmaps, and it's much
nicer to just detect what those should be once at startup.  This gives
us a chance to do the right thing for GLES.

It also, notably, fixes our format/type for depth 15 and 16 setup for
desktop GL, so that we actually allocate 16bpp (GL_RGB/565) on most
drivers instead of 32bpp (GL_RGB/UBYTE).

GLES still has regressions over desktop (2 regressions in llvmpipe
XTS, many in rendercheck), but I think this is a good baseline.

We currently support two modes of operation for RW PBO buffers: one

Paul Kocialkowski c98c7709c6 glamor: Propagate FBO allocation failure for picture to texture upload
When uploading a picture to a texture, glamor_upload_picture_to_texture
calls glamor_pixmap_ensure_fbo to ensure that there is backing FBO.
The FBO will be allocated if the picture's drawable pixmap does not have
one already, which can fail when there is no GL memory left.

glamor_upload_picture_to_texture checks that the call succeeded and will
enter the failure path if it did not. However, unlike many other
functions in glamor, this one has ret set to TRUE initially, so it needs
to be set to FALSE when a failure happens.

Otherwise, the error is not propagated and the failure path return TRUE.
This leads to a fault when trying to access the FBO pointer later on.

Adam Jackson 0a9415cf79 glamor_egl: Don't initialize on llvmpipe
Mesa started supporting GL_OES_EGL_image on llvmpipe in 17.3, after this
commit:

    commit bbdeddd5fd0b797e1e281f058338b3da4d98029d
    Author: Gurchetan Singh <gurchetansingh@chromium.org>
    Date:   Tue Aug 1 14:49:33 2017 -0700

        st/dri: add drisw image extension

That's pretty cool, but it means glamor now thinks it can initialize on
llvmpipe. This is almost certainly not what anyone wants, as glamor on
llvmpipe is pretty much uniformly slower than fb.

This fixes both Xorg and Xwayland to refuse glamor in such a setup.
Xephyr is left alone, both because glamor is not the default there and
because Xephyr+glamor+llvmpipe is one of the easier ways to get xts to
exercise glamor.

The (very small) downside of this change is that you lose DRI3 support.
This wouldn't have helped you very much (since an lp glamor blit is
slower than a pixman blit), but it would eliminate the PutImage overhead
for llvmpipe's glXSwapBuffers. A future change should add DRI3 support
for the fb-only case.

Lyude Paul 186a21c4ba glamor: Unbreak glamor_fd_from_pixmap()
When support for allocating GBM BOs with modifiers was added,
glamor_fd_from_pixmap() was changed so that it would return an error if
it got a bo with modifiers set from glamor_fds_from_pixmap(). The
problem is that on systems that support BOs with modifiers,
glamor_fds_from_pixmap() will always return BOs with modifiers.

This means that glamor_fd_from_pixmap() was broken entirely, which broke
a number of other things including glamor_shareable_fd_from_pixmap(),
which meant that modesetting using multiple GPUs with the modesetting
DDX was also broken. Easy reproducer:

- Find a laptop with DRI prime that has outputs connected to the
  dedicated GPU and integrated GPU
- Try to enable one display on each using the modesetting DDX
- Fail

Since there isn't a way to ask for no modifiers from
glamor_fds_from_pixmap, we create a shared _glamor_fds_from_pixmap()
function used by both glamor_fds_from_pixmap() and
glamor_fd_from_pixmap() that calls down to the appropriate
glamor_egl_fd*_from_pixmap() function.

Lukas F. Hartmann 7437b6dbde glamor_init: clamp GLSL to 120 if platform doesn't have instanced arrays
Hi,

I upgraded Xwayland and the assorted libraries from git masters today,
and noticed that glamor wouldn't work anymore on i.MX6/etnaviv. The
error was:

No provider of glVertexAttribDivisor found.  Requires one of:
    Desktop OpenGL 3.3
    OpenGL ES 3.0
    GL extension "GL_ANGLE_instanced_arrays"
    GL extension "GL_ARB_instanced_arrays"
    GL extension "GL_EXT_instanced_arrays"
    GL extension "GL_NV_instanced_arrays"

The problem is that etnaviv offers GLSL 140 on GL 2.1 and glamor
rendering assumes that glVertexAttribDivisor() is always available on
GLSL>=130, which is not the case here. Forcing GLSL 120 makes glamor
work fine again on this platform. After chatting with ajax in
#xorg-devel, the following solution was proposed.

This is my first time of submitting a patch, so please excuse me and
advise if I'm doing it wrong ;)

When compositing a no-reflect gradient, 'before' the gradient is empty,
but 'after' the gradient is padded with the final color.  Both sides are
supposed to be empty.

This is fixed by moving the virtual stops to match the first and last
client-supplied stops for no-reflect gradients, then causing everything
'before' the initial virtual stop and 'after' the final virtual stop to
emit rgba(0,0,0,0).  This does not impact gradients using the other
reflect modes.

Michel Dänzer 7c88977d33 glamor: Store the actual EGL/GLX context pointer in lastGLContext
Fixes subtle breakage which could sometimes trigger after a server reset
with multiple screens using glamor:

Screen A enters glamor_close_screen last and calls various cleanup
functions, which at some point call glamor_make_current to make sure
screen A's GL context is current. This sets lastGLContext to screen A's
&glamor_priv->ctx. Finally, glamor_close_screen calls
glamor_release_screen_priv, which calls free(glamor_priv).

Later, screen B enters glamor_init, which allocates a new glamor_priv.
With bad luck, this can return the same pointer which was previously
used for screen A's glamor_priv. So when screen B's glamor_init calls
glamor_make_current, lastGLContext == &glamor_priv->ctx, so MakeCurrent
isn't called for screen B's GL context, and the following OpenGL API
calls triggered by glamor_init mess up screen A's GL context.

The observed end result of this was a crash in glamor_get_vbo_space
because glamor_priv->vbo didn't match the GL context, though there might
be other possible outcomes.

Assigning the actual GL context pointer to lastGLContext prevents this
by preventing the false negative test in glamor_make_current.

interesting.  And when saying that we've started using GL

Eric Anholt 1549e30372 Add a Meson build system alongside autotools.
This is a work in progress that builds Xvfb, Xephyr, Xwayland, Xnest,
and Xdmx so far.  The outline of Xquartz/Xwin support is in tree, but
hasn't been built yet.  The unit tests are also not done.

The intent is to build this as a complete replacement for the
autotools system, then eventually replace autotools.  meson is faster
to generate the build, faster to run the bulid, shorter to write the
build files in, and less error-prone than autotools.

v2: Fix indentation nits, move version declaration to project(), use
    existing meson_options for version-config.h's vendor name/web.

Olivier Fourdan 7bfb87a213 glamor: an FBO is not needed for Xv pixmaps
It appears that on some hardware/diver combo such as nv30/nouveau, using
GL_ALPHA as format for 8-bit depth will cause an incomplete attachment
error (GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT) when trying to bind the
texture.

As a result, the FBO is NULL and glamor segfaults when trying to access
the FBO width/height in pixmap_priv_get_scale() in glamor_xv_render().

This happens with glamor-xv which uses 8-bit pixmaps, meaning that on
such hardware/driver, trying to play a video using Xv will lead to a
crash of the Xserver. This affects Xwayland, Xephyr, modesetting driver
with glamor accel.

But the use of an FBO is not actually needed for glamox-xv, so by
disabling FBO at pixmap creation, we can avoid the issue entirely.

Olivier Fourdan 8805a48ed3 glamor: avoid a crash if texture allocation failed
Texture creation in _glamor_create_tex() can fail if a GL_OUT_OF_MEMORY
is raised, in which case the texture returned is zero.

But the texture value is not checked in glamor_create_fbo() and glamor
will abort in glamor_pixmap_ensure_fb() because the fbo->tex is 0:

  Truncated backtrace:
  Thread no. 1 (10 frames)

Check the value returned by _glamor_create_tex() in glamor_create_fbo()
and return NULL in the texture is zero.

All callers of glamor_create_fbo() actually check the returned value and
will use a fallback code path if it's NULL.

The fbo_array of a given glamor pixmap can be NULL in some cases, as
glamor_create_fbo_array() can fail to allocate the FBO array.

If this is the case, glamor_pixmap_fbo_at() will return NULL even though
the box index is valid, and glamor_set_destination_drawable() simply
assumes glamor_pixmap_fbo_at() will return an FBO prior to pass the
value to glamor_set_destination_pixmap_fbo(), which will segfault.

We need a way for glamor_set_destination_drawable() to fail safely and
let the caller know about the failure.

If the libEGL we are using has eglGetPlatformDisplayEXT, yet it still

type (e.g. EGL_PLATFORM_GBM_MESA) passed in, and then returning NULL is
the right thing to do.

This avoids falling back to an eglGetDisplay() implementation which does
not understands the passed in gbm handle, treats it as a pointer to
something else completely, followed by a crash sooner or later.

Specifically this fixes using the nvidia binary driver, with nvidia's
libEGL + the modesetting driver on a secondary GPU crashing inside

The extension does not exist in the registry, thus needs to know they're
using EGL 1.5 in order to determine the eglGetPlatformDisplay function
pointer is valid.

Thus brings us into some lovely circular dependency.

Since mesa won't be able (in the foreseeable future) to export the KHR
flavour of extension (another way one could assume that EGL 1.5 is
available) just drop all the heuristics and use the
EGL_EXT_platform_base extension.

In practise (checked with the Mali driver) any EGL 1.5 driver will

When a GPU gets hotplugged while X is already running, glamor_egl_init()
gets called and changes the current egl context, without updating
lastGLContext, potentially causing the next glamor call on another GPU to
run in the wrong context.

This causes glamor to e.g. crash in the next glamor_create_pixmap() call
(called through the master's screen->CreatePixmap), note this is not the
only troublesome entry point I've seen other backtraces when using a
compositing window manager.

Set lastGLContext to NULL to force the next glamor_make_current() call
to set the right context.

Note that we cannot use glamor_make_current() here to replace the
eglMakeCurrent() call and update lastGLContext for us because
glamor_make_current takes a glamor_priv struct as argument and that
has not been created yet when glamor_egl_init() gets called.

Michel Dänzer cba28d572a glamor: Handle bitplane in glamor_copy_fbo_cpu
This can significantly speed up at least some CopyPlane cases, e.g.
indirectly for stippled fills.

v2:
* Make temporary pixmap the same size as the destination pixmap
  (instead of the destination drawable size), and fix coordinate
  parameters passed to fbCopyXtoX and glamor_upload_boxes. Fixes
  incorrect rendering with x11perf -copyplane* and crashes with the
  xscreensaver phosphor hack.
v3:
* Make the change a bit more compact and hopefully more readable by
  re-using the existing src_* locals in the bitplane case as well.

Eric Anholt 950ffb8d6f glamor: Remove the FBO cache.
It is a modest performance improvement (2.7% on Intel), with the
significant downside that it keeps extra pixmap contents laying around
for 1000 BlockHandlers without the ability for the system to purge
them when under memory pressure, and tiled renderers don't know that
we could avoid reading their current contents when beginning to render
again.  We could use the FB invalidate functions, but they aren't
always available, aren't hooked up well in Mesa, and would eat into
the performance gains of having the cache.

Keith Packard fb1edccf3c dix: Call screen block/wakeup handlers closest to blocking [v3]
The screen block and wakeup handlers are the only ones which provide a
well known ordering between the wrapping layers; placing these as
close as possible to the server blocking provides a way for the driver
to control the flow of execution correctly.

Switch the shadow code to run in the screen block handler so that it
now occurrs just before the server goes to sleep.

Switch glamor to call down to the driver after it has executed its own
block handler piece, in case the driver needs to perform additional
flushing work after glamor has called glFlush.

These changes ensure that the following modules update the screen in
the correct order:

animated cursors        (uses RegisterBlockAndWakeupHandlers dynamically)
composite               (dynamic wrapping)
misprite                (dynamic wrapping)
shadow                  (static wrapping)
glamor                  (static wrapping)
driver                  (static wrapping)

It looks like there's still a bit of confusion between composite and
misprite; if composite updates after misprite, then it's possible
you'd exit the block handler chain with the cursor left hidden. To fix
that, misprite should be wrapping during ScreenInit time and not
unwrapping. And composite might as well join in that fun, just to make
things consistent.

[v2] Unwrap BlockHandler in shadowCloseScreen (ajax)
[v3] ephyr: Use screen block handler for flushing changes

ephyr needs to make sure it calls glXSwapBuffers after glamor finishes
its rendering. As the screen block handler is now called last, we have
to use that instead of a registered block/wakeup handler to make sure
the GL rendering is done before we copy it to the front buffer.

Keith Packard 181a4bd0cc glamor: Preserve GL_RED bits in R channel when destination is GL_RED [v2]
A1 and A8 pixmaps are usually stored in the Red channel to conform
with more recent GL versions. When using these pixmaps as mask values,
that works great. When using these pixmaps as source values, then the
value we want depends on what the destination looks like.

For RGBA or RGB destinations, then we want to use the Red channel
for A values and leave RGB all set to zero.

For A destinations, then we want to leave the R values in the Red
channel so that they end up in the Red channel of the output.

This patch adds a helper function, glamor_bind_texture, which performs
the glBindTexture call along with setting the swizzle parameter
correctly for the Red channel. The swizzle parameter for the Alpha
channel doesn't depend on the destination as it's safe to leave it
always swizzled from the Red channel.
