The setTexBuffer2 hook from GLX is used to implement glxBindTexImageEXT
which has tighter restrictions than just "it's shared". In particular,
it says that any rendering to the image while it is bound causes the
contents to become undefined.
The GLX_EXT_texture_from_pixmap extension provides us with an acquire
and release in the form of glXBindTexImageEXT and glXReleaseTexImageEXT.
The extension spec says,
"Rendering to the drawable while it is bound to a texture will leave
the contents of the texture in an undefined state. However, no
synchronization between rendering and texturing is done by GLX. It
is the application's responsibility to implement any synchronization
required."
From the EGL 1.4 spec for eglBindTexImage:
"After eglBindTexImage is called, the specified surface is no longer
available for reading or writing. Any read operation, such as
glReadPixels or eglCopyBuffers, which reads values from any of the
surface’s color buffers or ancillary buffers will produce
indeterminate results. In addition, draw operations that are done
to the surface before its color buffer is released from the texture
produce indeterminate results
In other words, between the bind and release calls, we effectively own
those pixels and can assume, so long as we don't crash, that no one else
is reading from/writing to the surface. The GLX and EGL implementations
call the setTexBuffer2 and releaseTexBuffer function pointers that the
driver can hook.
In theory, this means that, between BindTexImage and ReleaseTexImage, we
own the pixels and it should be safe to track aux usage so we
can avoid redundant resolves so long as we start off with the right
assumption at the start of the bind/release pair.
In practice, however, X11 has slightly different expectations. It's
expected that the server may be drawing to the image at the same time as
the compositor is texturing from it. In that case, the worst expected
outcome should be tearing or partial rendering and not random corruption
like we see when rendering races with scanout with CCS. Fortunately,
the GEM rules about texture/render dependencies save us here. If X11
submits work to write to a pixmap after the compositor has submitted
work to texture from it, GEM inserts a dependency between the compositor
and X11. If X11 is using a high-priority context, this will cause the
compositor to get a temporarily boosted priority while the batch from
X11 is waiting on it. This means that we will never have an actual race
between X11 and the compositor so no corruption can happen.
Unfortunately, however, this means that X11 will likely be rendering to it
between the compositor's BindTexImage and ReleaseTexImage calls. If we
want to avoid strange issues, we need to be a bit careful about
resolves because we can't really transition it away from the "default"
aux usage. The only case where this would practically be a problem is
with image_load_store where we have to do a full resolve in order to use
the image via the data port. Even there it would only be a problem if
batches were split such that X11's rendering happens between the resolve
and the use of it as a storage image. However, the chances of this
happening are very slim so we just emit a warning and hope for the best.
This commit adds a new helper intel_miptree_finish_external which resets
all aux state to whatever ISL says is the right worst-case "default" for
the given modifier. It feels a little awkward to call it "finish"
because it's actually an acquire from the perspective of the driver, but
it matches the semantics of the other prepare/finish functions. This
new helper gets called in intelSetTexBuffer2 instead of make_shareable.
We also add an intelReleaseTexBuffer (we passed NULL to releaseTexBuffer
before) and call intel_miptree_prepare_external in it. This probably
does nothing most of the time but it means that the prepare/finish calls
are properly matched.

This requires moving the _MaxLevel handling up to the callers. Another
user of intel_finalize_mipmap_tree will be added later that depends on
_MaxLevel not being modified.

These two paths are basically the same. There's no good reason to have

The old return type of GLuint was wonky - it should have been bool.
But nothing actually uses the return value anyway, so we can just drop
that and make it a void function.
In theory, it might make sense to ask whether the texture validated
successfully, but just checking intel_obj->mt != NULL works for that.

I think pretty much everyone agrees that having more than a single bool as a
function argument is bordering on a bad idea. What sucks about the current
code is in several instances it's necessary to propagate these boolean
selections down to lower layers of the code. This requires plumbing (mechanical,
but still churn) pretty much all of the miptree functions each time. By
introducing the flags paramater, it is possible to add miptree constraints very
easily.
The use of this, as is already the case, is sometimes we have some information
at the time we create the miptree that needs to be known all the way at the
lowest levels of the create/allocation, disable_aux_buffers is currently one
such example. There will be another example coming up in a few patches.
v2:
Tab fix. (Ben)
Long line fixes (Topi)
Use anonymous enum instead of #define for layout flags (Chad)
Use 'X != 0' instead of !!X (everyone except Chad)

Added intel_readpixels_tiled_mempcpy and intel_gettexsubimage_tiled_mempcpy
functions. These are the fast paths for glReadPixels and glGetTexImage.
On chrome, using the RoboHornet 2D Canvas toDataURL test, this patch cuts
amount of time spent in glReadPixels by more than half and reduces the time
of the entire test by 10%.
v2: Jason Ekstrand <[email protected]>
- Refactor to make the functions look more like the old
intel_tex_subimage_tiled_memcpy
- Don't export the readpixels_tiled_memcpy function
- Fix some pointer arithmatic bugs in partial image downloads (using
ReadPixels with a non-zero x or y offset)
- Fix a bug when ReadPixels is performed on an FBO wrapping a texture
miplevel other than zero.
v3: Jason Ekstrand <[email protected]>
- Better documentation fot the *_tiled_memcpy functions
- Add target restrictions for renderbuffers wrapping textures
v4: Jason Ekstrand <[email protected]>
- Only check the return value of brw_bo_map for error and not bo->virtual
v5: Jason Ekstrand <[email protected]>
- Don't unnecessarily repeat a comment

blitter
v3: Properly support copying between two places on the same texture in the
memcpy fallback
v4: Properly handle blit between the same two images in the fallback path
v5: Properly handle blit between the same two compressed images in the

This makes brw_context available in every function that used
intel_context. This makes it possible to start migrating fields from
intel_context to brw_context.
Surprisingly, this actually removes some code, as functions that use
OUT_BATCH don't need to declare "intel"; they just use "brw."

This removes the delayed texture upload optimization from 965, in exchange for
bringing us closer to PBO support. It also disables SGIS_generate_mipmap,
which didn't seem to be working before anyway, according to the lodbias demo.
|
| |
|
|
|
| |
The only functional difference should be that 965 now gets the optimization
where textures default to 16bpp when the screen is 16bpp.

This driver comes from Tungsten Graphics, with a few further modifications by
Intel.
