belong in driver code
The implementation of texture <-> pixel-buffer transfers in drivers common layer
includes certain error checks and argument validation that don't belong there,
considering how the Mesa codebase is laid out. These are higher level
validations that, if necessary, should be performed earlier (i.e, in GL API
entry points).
This patch simply removes these error checks from driver code.
For more information, see discussion at

System headers may contain C++ declarations, which cannot be given C
linkage. For this reason, include statements should never occur
inside extern "C".
This patch moves the C linkage statements to enclose only the
declarations within a single header.

The yoffset needs to be interpreted as a slice offset for 1D array
textures. This patch implements that by moving the yoffset into
zoffset similar to how it moves the height into depth.

Now that a layered source PBO is interpreted as a single tall 2D image
it's quite easy to accept the image height packing option by just
creating an image that is tall enough to include the image padding.
I'm not sure whether the image height property should affect 1D_ARRAY
textures. My intuition and interpretation of the GL spec (which is a
bit vague) would be that it shouldn't. However the software fallback
path in Mesa uses the property for packing but not for unpacking. The
binary NVidia driver uses it for both. This patch doesn't use it for
either case so it is different from the software fallback. There is
some discussion about this here:
http://lists.freedesktop.org/archives/mesa-dev/2015-February/077925.html
This is tested by the texsubimage Piglit test with the array and pbo
arguments. Previously this test was skipping this code path because it
always sets the image height.
I've also tested it by modifying the getteximage-targets test. It
wasn't using this code path before because it was using the default
texture object so this code couldn't successfully create a frame
buffer. I also modified it to add some image padding with the image
height in the PBO.

This reverts commit 546aba143d13ba3f993ead4cc30b2404abfc0202.
I think the changes to the calls to glBlitFramebuffer from this patch
are no different to what it was doing previously because it used to
set height to 1 before doing the blits. However it was introducing
some problems with the blit for layer 0 because this was no longer
special cased. It didn't fix problems with the yoffset which needs to
be interpreted as a slice offset. I think a better solution would be
to modify the original if statement to cope with the yoffset.

Previously, there were bugs where if the app set a scissor it could affect
the area of the texture that was downloaded. There was also potential that
the framebuffer SRGB state could affect downloads. This ensures that those
will get saved/restored and can't affect the texture download.

This moves the line setting immutability for the texture to after
_mesa_initialize_texture_object so that the initializer function will not
cancel it out. Moreover, because of the ARB_texture_view extension, immutable
textures must have NumLayers > 0, or depth will equal (0-1)=0xFFFFFFFF during
SURFACE_STATE setup, which triggers assertions.
v2: Review from Kenneth Graunke:
- Include more explanation in the commit message.

When restoring the current state in _mesa_meta_end it was previously trying to
copy the on-going sample count of the current occlusion query into the new
query after restarting it so that the driver will continue adding to the
previous value. This wouldn't work for two reasons. Firstly, the query might
not be ready yet so the Result member will usually be zero. Secondly the saved
query is stored as a pointer to the query object, not a copy of the struct, so
it is actually restarting the exact same object. Copying the result value is
just copying between identical addresses with no effect. The call to
_mesa_BeginQuery will have always reset it back to zero.
This patch fixes it by making it actually wait for the query object to be
ready before grabbing the previous result. The downside of doing this is that
it could introduce a stall but I think this situation is unlikely so it might
not matter too much. A better solution might be to introduce a real
suspend/resume mechanism to the driver interface. This could be implemented in
the i965 driver by saving the depth count multiple times like it does in the
i945 driver.

In order to implement ARB_DIRECT_STATE_ACCESS, many GL API functions must now
rely on a backend that both traditional and DSA functions can use. For
instance, _mesa_TexStorage2D and _mesa_TextureStorage2D both call a backend
function _mesa_texture_storage that takes a context and a texture object as
arguments. The backend is named _mesa_texture_storage so that Meta can call
it and avoid looking up the context and the texture object. However, backend
names often look very close to the names of software fallbacks (ie.
_mesa_alloc_texture_storage). For this reason, software fallbacks have been
renamed for clarity to have the form _mesa_[Driver function name]_sw.

Extension enables doing a multisample buffer resolve and buffer
scaling using a single glBlitFrameBuffer() call. Currently, we
have this extension implemented in BLORP which is only used by
SNB and IVB. This patch implements the extension in meta path
which makes it available to Broadwell.
Implementation features:
- Supports scaled resolves of 2X, 4X and 8X multisample buffers.
- Avoids unnecessary shader compilations by storing the pre compiled
shaders for each supported sample count.
- Uses bilinear filtering for both GL_SCALED_RESOLVE_FASTEST_EXT and
GL_SCALED_RESOLVE_NICEST_EXT filter options. This is an allowed
behavior in the extension's spec.
- I tried doing bicubic filtering for GL_SCALED_RESOLVE_NICEST_EXT
filter. It made the edges in the image look little smoother but
the image gets blurred causing no overall quality improvement.
For now I have dropped the idea of doing different filtering for
nicest filter.
V2:
- Minor changes to simplify the fragment shader.
- Refactor the code to move i965 specific sample_map computation out
of Meta. We now use ctx->Const.SampleMap{2,4,8}x variables initialized
by the driver.
- Use a simple msaa resolve shader for scaled resolves with scaling
factor = 1.0.
V3:
- Make changes to create a string out of ctx->Const.SampleMap{2,4,8}x
variables and use it in fragment shader.
V4:
- Make changes to use uint8_t type ctx->Const.SampleMap{2,4,8}x
variables.
