This patch validates those sampler views with backing copy
of texture whose original copy has been updated since the
view is last validated.
This is done here at draw time because the texture binding might not
have modified, hence validation is not triggered at state update time,
and yet the texture might have been updated in another context, so
we need to re-validate the sampler view in order to update the backing
copy of the updated texture.

This fixes a rendering flickering issue with Photoshop running in
Linux VM with HWversion 11. The problem is Photoshop renders to texture A
in context X, and then bind texture A to context Y. The first time
when texture A is bound to context Y, cso calls pipe->set_sampler_views().
Validation of sampler views is done, rendering is fine.
But when texture A is rendered to again in context X, and rebound in
context Y, cso skips pipe->set_sampler_views() because texture A is already
bound in context Y. SVGA driver is not given a chance to re-validate
the texture binding, the backing copy of the texture is not updated,
and hence causes black image.

7 years agomesa: Require mipmap completeness for glCopyImageSubData() at times.
Kenneth Graunke [Thu, 23 Feb 2017 23:04:52 +0000 (15:04 -0800)]
mesa: Require mipmap completeness for glCopyImageSubData() at times.

This patch makes glCopyImageSubData require mipmap completeness when the
texture object's built-in sampler object has a mipmapping MinFilter.
This is apparently the de facto behavior and mandated by Android's CTS.

One exception is that we ignore format based completeness rules
(specifically integer formats with linear filtering), as this is
also the de facto behavior that until recently was mandated by the
OpenGL 4.5 CTS.

This was discussed with both the OpenGL and OpenGL ES working groups,
and while everyone agrees this behavior is unfortunate and complicated,
it is what it is at this point.  There was little appetite for relaxing
restrictions given that all conformant Android drivers followed the
mipmapping rule, and all conformant GL 4.5 implementations ignored the
integer/linear rule.

i965: Drop index buffer re-alignment code.

This shouldn't ever happen - GL requires it to be aligned:

   "Clients must align data elements consistent with the requirements
    of the client platform, with an additional base-level requirement
    that an offset within a buffer to a datum comprising N basic
    machine units be a multiple of N."

Mesa should reject unaligned index buffers for us - we shouldn't have
to handle them in the driver.

Note that Gallium already makes this assumption.
