We will typically have a current context when we need to lookup the image,
but the lookup implementation don't need it so drop it.
|
|
We can't expect to have a context when this is called, and we don't need one
so just require a __DRIscreen instead.

Only r200 implemented it.

The presence of this extension indicates to the DRI driver that the
loader will call invalidate in the __DRI2_FLUSH extension, whenever
the needs to query for new buffers. This means that the DRI driver
can drop the polling in glViewport().

Add a new DRI2 configuration query extension. Allows for DRI2 client
code to query for common DRI2 configuration options.

__NOT_HAVE_DRM_H is a like a feature, defined by default on specific platforms
and allows to be defined externally as well.
__NOT_HAVE_DRM_H should only be used by xserver and mesa swrast_dri drivers
|
|
These are used for implementing the various EGLImage extensions.
|
|
When a buffer invalidation event is received from the X server, the
"invalidate" hook of the DRI2 flush extension is executed: A generic
implementation (dri2InvalidateDrawable) is provided that just bumps
the "pStamp" sequence number in __DRIdrawableRec.
For old servers not supporting buffer invalidation events, the
invalidate hook will be called before flushing the fake front/back
buffer (that's typically once per frame -- not a lot worse than the
situation we were in before).
No effort has been made on preserving backwards compatibility with
version 2 of the flush extension, but I think it's acceptable because
AFAIK no released stack is making use of it.

This used to take GLX tokens, but the DRI interface can't depend on GLX
defines. We fix this by introducing DRI tokens that have the same value
as the GLX texture format tokens.
|
|
Support the new DRI2 protocol request, DRI2SwapBuffers, in both direct
and indirect rendering context. This request allows the display server
to optimize back->front swaps (e.g. through page flipping) and allows us
to more easily support other GLX features like swap interval and the OML
sync extension in DRI2.

Here is a couple of fixes for GNU/Hurd:
- dri_interface.h: no libdrm support either.
- configure.ac:
- GNU/Hurd is a GNU OS with _GNU_SOURCE and PTHREADS.
- GNU needs a couple of flags like other OSes

This requires upgrading the interface so that the argument to
glXBindTexImageEXT isn't just dropped on the floor. Note that this only
fixes the accelerated path on Intel, as Mesa's texture format support is
missing x8r8g8b8 support (right now, GL_RGB textures get uploaded as a8r8gb8,
but in this case we're not doing the upload so we can't really work around it
that way).
Fixes bugs with compositors trying to use shaders that use alpha channels, on
windows without a valid alpha channel. Bug #19910 and likely others as well.

We probably shouldn't be including sys/types.h at all, but let's leave that
for another time.

Add DRI2 direct rendering support to libGL and add DRI2 client side
protocol code. Extend the GLX 1.3 create drawable functions in
glx_pbuffer.c to call into the DRI driver when possible.
Introduce __DRIconfig, opaque struct that represents a DRI driver
configuration. Get's rid of the open coded __GLcontextModes in the
DRI driver interface and the context modes create and destroy
functions that the loader was requires to provide. glcore.h is no
longer part of the DRI driver interface. The DRI config is GL binding
agnostic, that is, not specific to GLX, EGL or other bindings.
The core API is now also an extension, and the driver exports a list
of extensions as the symbol __driDriverExtensions, which the loader
must dlsym() for. The list of extension will always include the DRI
core extension, which allows creating and manipulating DRI screens,
drawables and contexts. The DRI legacy extension, when available,
provides alternative entry points for creating the DRI objects that
work with the XF86DRI infrastructure.
Change DRI2 client code to not use drm drawables or contexts. We
never used drm_drawable_t's and the only use for drm_context_t was as
a unique identifier when taking the lock. We now just allocate a
unique lock ID out of the DRILock sarea block. Once we get rid of the
lock entirely, we can drop this hack.
Change the interface between dri_util.c and the drivers, so that the
drivers now export the DriverAPI struct as driDriverAPI instead of the
InitScreen entry point. This lets us avoid dlsym()'ing for the DRI2
init screen function to see if DRI2 is supported by the driver.
|
|
This fixes a problem where texturing from the same Pixmap more than
once per batchbuffer would hang the DRI driver. We just use the region
associated with the front left renderbuffer of the __DRIdrawable for
texturing, which avoids creating different regions for the same BO.
This change also make GLX_EXT_texture_from_pixmap work for direct
rendering, since tracking the __DRIdrawable -> BO handle now uses
the standard DRI2 event buffer. Of course, DRI2 direct rendering
doesn't exist yet.
Finally, this commit bumps the DRI interface version again, accounting
for the change in the DRI_TEX_BUFFER extension and the change in
commit 0bba0e5be7a4a7275dad1edc34bdcc134ea1f424 to pass in the
event buffer head index on drawable creation.
|
|
The DRI driver needs to know where in the buffer to start reading.
|
|
When the DRI doesn't parse the event buffer for a while, the X server
may overwrite data that the driver didn't get a chance to look at. The
reemitDrawableInfo callback requests that the X server reemit all info
for the specified drawable. To make use of this, the drive needs to know
the new tail pointer so it know where to start reading from.
|
|
Instead of passing in a fixed struct, the loader now passes in a list
of __DRIextension structs, to advertise the functionality it can provide
to the driver. Each extension is individually versioned and can be
extended or phased out as the interface develops.
|
|
Right now the DRI2 screen constructor takes 3 different versions:
DRI, DDX and DRM. This is mostly useless, though:
DRI: The DRI driver doesn't actually care about the DRI protocol,
it only talks to the loader, which in turn speaks DRI protocol. Thus,
the DRI protocol version is of not interest to the DRI driver, but it
needs to know what functionality the loader provides. At this point
that's reflected in the __DRIinterfaceMethods struct and the
internal_version integer.
DDX: The DDX version number is essentially used to track extensions
to the SAREA. With DRI2 the SAREA consists of a number of versioned,
self-describing blocks, so the DDX version is no longer interesting.
DRM: We have the fd, lets just ask the kernel ourselves.
|
|
The DriverAPI is internal to the DRI drivers and GetDrawableMSC
obsoletes GetMSC. Also, since the DRI driver interface has not yet
been released, just drop the getMSC function from the DRI interface
instead using the ABI preserving version mechanism.
Finally, using void pointer privates in the DRI interface is not allowed,
always pass the actual types around (__DRIdrawable in this case) to
enhance type safety and readability of the code.
|
|
Currently only implemented for intel hw.

Consolidate support for synchronizing to and retrieving vblank counters. Also
fix the core vblank code to return monotonic MSC counters, which are required
by some GLX extensions. Adding support for multiple pipes to a low level
driver is fairly easy, the Intel 965 driver provides simple example code (see
intel_buffers.c:intelWindowMoved()).
The new code bumps the media stream counter extension version to 2 and adds a
new getDrawableMSC callback. This callback takes a drawablePrivate pointer,
which is used to calculate the MSC value seen by clients based on the actual
vblank counter(s) returned from the kernel. The new drawable private fields
are as follows:
- vblSeq - used for tracking vblank counts for buffer swapping
- vblFlags - flags (e.g. current pipe), updated by low level driver
- msc_base - MSC counter from the last time the current pipe changed
- vblank_base - kernel DRM vblank counter from the last time the pipe changed
Using the above variables, the core vblank code (in vblank.c) can calculate a
monotonic MSC value. The low level DRI drivers are responsible for updating
the current pipe (by setting VBLANK_FLAG_SECONDARY for example in vblFlags)
along with msc_base and vblank_base whenever the pipe associated with a given
drawable changes (again, see intelWindowMoved for an example of this).
Drivers should fill in the GetDrawableMSC DriverAPIRec field to point to
driDrawableGetMSC32 and add code for pipe switching as outlined above to fully
support the new scheme.
|
|
This is for consistency with glproto. The GL_CORE defines should probably be
dropped.
