Adam Jackson ea483af99a glx: Move Composite's synthetic visuals to a different select group
Should you find yourself using a 16bpp display while also using a
compositor, you poor soul, you may find that your GLX applications
behave strangely; in particular, glxgears will be transparent. This is
because it clears to (0,0,0,0) which is transparent if you honor alpha,
and it will choose the synthetic visual because it has the most
available r/g/b bits.

To avoid this, bump synthetic visuals to a higher (less-preferred)
select group. Unless the client explicitly asks for non-zero alpha bits,
this will prefer any rgb565 visual ahead of the argb8888 visual.

Hans de Goede 445271ec00 glx: Always enable EXT_texture_from_pixmap for DRI swrast glx
Prior to commit f95645c6f7 ("glx: Don't enable EXT_texture_from_pixmap
unconditionally") DRI glx would always advertise EXT_texture_from_pixmap.

That commit moved the setting of the extension in the extension bits from
__glXInitExtensionEnableBits to its callers so that
__glXInitExtensionEnableBits can be used more generally, but at the same
time made the setting of EXT_texture_from_pixmap conditionally on
__DRI_TEX_BUFFER being present.

This has result in an unintended behavior change which breaks e.g.
compositors running on llvmpipe. This commit makes the DRI swrast glx code
advertise EXT_texture_from_pixmap unconditionally again fixing this.

Fixes: f95645c6f7 ("glx: Don't enable EXT_texture_from_pixmap unconditionally")

Jon Turney f5f4d32ac7 Add Windows-DRI extension
If windowsdriproto headers are available, build a Windows-DRI extension,
which supports requests to enable local clients to directly render GL to a
Windows drawable:

- a query to check if WGL is being used on a screen
- a query to map a fbconfigID to a native pixelformatindex
- a query to map a drawable to a native handle

Windows-DRI can only be useful if we are using WGL, so make an note if WGL
is active on a screen.

Make validGlxDrawable() public

Adjust glxWinSetPixelFormat() so it doesn't require a context, just a
screen and config.

That enables factoring out the deferred drawable creation code as
glxWinDeferredCreateDrawable()

Enhance glxWinDeferredCreateDrawable(), so that pixmaps are placed into a
file mapping, so they exist in memory which can be shared with the direct
rendering process.

Currently, this file mapping is accessed by a name generated from the XID.
This will not be unique across multiple server instances. It would perhaps
be better, although more complicated, to use an anonymous file mapping, and
then duplicate the handle for the direct rendering process.

Use glxWinDeferredCreateDrawable() to ensure the native handle exists for
the Windows-DRI query to map a drawable to native handle.

v2:
Various printf format warning fixes

v3:
Fix format warnings on x86
Move some uninteresting windows-dri output to debug log level

v4:
check for windowsdriproto when  --enable-windowsdri
use windowsdriproto_CFLAGS

Adam Jackson 392da389d7 glx: Fix computation of GLX_X_RENDERABLE fbconfig attribute
>From the GLX spec:

    "GLX_X_RENDERABLE is a boolean indicating whether X can be used to
    render into a drawable created with the GLXFBConfig. This attribute
    is True if the GLXFBConfig supports GLX windows and/or pixmaps."

Every backend was setting this to true unconditionally, and then the
core ignored that value and sent true unconditionally on its own. This
is broken for ARB_fbconfig_float and EXT_fbconfig_packed_float, which
only apply to pbuffers, which are not renderable from non-GLX APIs.

Instead compute GLX_X_RENDERABLE from the supported drawable types. The
dri backends were getting _that_ wrong too, so fix that as well.

This is not a functional change, as there are no mesa drivers that claim
to support __DRI_ATTRIB_{UNSIGNED_,}FLOAT_BIT yet.

Guilherme Quentel Melo a134d1e7ea glx: avoid memory leak when using indirect rendering
When multiple processes are using GL with indirect rendering a race
condition can make drawables refcount never drop to zero.

This situation could happen when there are many X clients using indirect
GLX:

1 - client1: calls glXMakeCurrent

2 - client2: calls glXMakeCurrent
This is the first context switch for this client. So old_context_tag=0

3 - client1: calls glXRender
For the client, its context is already current.
For the server side lastGLContext points to client2's context.

chance of working.

v4 also specifies that both extension strings should be advertised for
compatibility with clients written against v1 of the extension spec, so
add the es_profile bit to the extension list and enable it whenever we
would enable es2_profile.

Jon TURNEY bc71081f0e glx: Fix crash when a client exits without deleting GL contexts
With the previous patches applied, we now have crash due to use-after-free when
a client exits without deleting all it's GL contexts

On client exit, CloseDownClient first calls glxClientCallback() with
ClientStateGone, which calls __glXFreeContext() directly.

Subsequently CloseDownClient() frees all the clients resources, which leads to
ContextGone() being called for a context resource where the context has already
been freed.

Fix this by modifiying glxClientCallback() to free the context resource.

Also make __glXFreeContext() static, as calling it directly leads to this
problem, instead the context resource should be released.

With the previous patches applied, this can be demonstrated with e.g. glxinfo,
which doesn't delete it's context before exit.

This seems to miss the whole point of the idExists flag, as it makes the
lifetime of that being true the same as the lifetime of the Context resource.

The previously current context tag is always given in a MakeContextCurrent

has been deleted), so this leads to BadContextTag errors.

Adam Jackson 17ed7ac1fe glx: Lie about GLX_Y_INVERTED_EXT
Well, that was lame.  The problem with reporting y inversion honestly is
that libGL asks the driver _its_ opinion of Y inversion, which it just
fabricates from whole cloth.  So then when libGL goes to compare the
driver's idea of fbconfigs with that of the server - a fairly dumb idea
to begin with - nothing matches, and direct rendering fails, and
sadness.

So until the DRI drivers are fixed we should just continue to lie about
Y inversion.  GLX_DONT_CARE is what libGL would make up for that
attribute if we hadn't sent it, so just send that instead.

Adam Jackson be6680967a glx: convert to direct GL dispatch (v2)
We now expect to be linked against something that provides the GL API,
instead of manually grubbing about in the DRI driver's dispatch table.
Since the GLX we expose calls GL functions that are meant to be looked
up dynamically, also add a way to thunk through to GetProcAddress.

This includes a refresh of the generated sources, which requires a
correspondingly new Mesa.

The GetProcAddress stubs are at the moment merely enough to make this
link against Mesa 9.2, but should really be provided for everything not
in the OpenGL 1.2 ABI.

v2: Explicitly hide the GetProcAddress stubs so we can't conflict with
libGL symbols; fix leading tab/space issues [anholt]

Adam Jackson 8aacf47e17 glx: Remove DRI1 AIGLX (v2)
Mesa doesn't ship DRI1 drivers as of 8.0, which is about 18 months and
three releases ago.  The main reason to have wanted DRI1 AIGLX was to
get a GLX compositor working, but DRI1's (lack of) memory management API
meant that the cost of a GLX compositor was breaking direct GLX apps,
which isn't a great tradeoff.

Of the DRI1 drivers Mesa has dropped, I believe only mga stands to lose
some functionality here, since it and only it has support for
NV_texture_rectangle.  Since that's required for every extant GLX
compositor I know of, I conclude that anybody with a savage, say, would
probably not notice AIGLX going away, since they wouldn't be running a
GLX compositor in the first place.

In the future we'd like to use GL in the server in a more natural way,
as just another EGL client, including in the GLX implementation itself.
Since there's no EGL implemented for DRI1 drivers, this would already
doom AIGLX on DRI1 (short of entirely forking the GLX implementation,
which I'm not enthusiastic about).

v2: Remove DRI1 from AIGLX conditionals in configure.ac [anholt]

Adam Jackson 276d8057aa glx: Fix memory leak in context garbage collection (v2)
I broke this, back in:

    commit a48dadc98a
    Author: Adam Jackson <ajax@redhat.com>
    Date:   Mon Mar 21 11:59:29 2011 -0400

	glx: Reimplement context tags

In that, I changed the glx client state to not explicitly track the list
of current contexts for the client (since that was what we were deriving
tags from).  The bug was that I removed the code for same from
glxClientCallback without noticing that it had the side effect of
effectively de-currenting those contexts, so that ContextGone could free
them.  So, if you had a client exit with a context still current, the
context's memory would leak.  Not a huge deal for direct clients, but
viciously bad for indirect, since the swrast context state at the bottom
of Mesa is like 15M.

Fix this by promoting Bool isCurrent to ClientPtr currentClient, so that
we have a back-pointer to chase when walking the list of contexts when
ClientStateGone happens.

v2: Explicitly call __glXFreeContext on the ClientStateGone path.  Our
current context might be one we got from EXT_import_context and whose
creating client has since died.  Without the explicit call, the creating
client's FreeClientResources would not free the context because it's
still current, and the using client's FreeClientResources would not free
the context because it's not an XID it created.  This matches the logic
from a48dadc.

In __glXScreenInit() we generate the set of GLX visuals in two steps:
first we match each pre-existing X visual with a corresponding
FBConfig, then we generate a new X visual to correspond to all the
remaining FBConfigs.

The first step is used for the two default 24-bit visuals (true color
and direct color) and for the 32-bit visual.  If windowsystem
multisampling is enabled in Mesa, we need to ensure that none of these
three visuals gets matched to a multisampled config.

Fixes a bug with windowsystem multisampling in gnome-shell.  If the X
server happens to match up a multisampled FBConfig to the 32-bit
visual, gnome-shell will try to use it to read pixels from
alpha-blended windows (such as gnome-terminal), resulting in no window
appearing on screen.

Commit 84956ca4 bogusly adds GLX_INTEL_swap_event to the extensions reported

"DRI2 supports this now - and already enables it explicitly - but drisw does

once and wait forever for an event that's not coming."

(A similar bug for direct swrast is already fixed in mesa commit 25620eb1)

(Note that this may be papering over the cracks somewhat, as if we do report
GLX_INTEL_swap_event, some clutter apps fail with GLXBadDrawable calling
GLXChangeDrawableAttributes to change the setting of GLX_BUFFER_SWAP_COMPLETE_INTEL_MASK

Jon TURNEY 06ac7937fc Restore extern to the declaration of __glXDRISWRastProvider
b86aa74 dropped the 'extern' from the declaration of __glXDRISWRastProvider

This turns out to be important to me, as without it, the final link only gets
the tentative definition of __glXDRISWRastProvider implied by the declaration,
and not the proper one from glxdriswrast.c, presumably because nothing else
references anything in the object that file generates.
