int).  But this could fail in out of memory conditions.  If we failed to

In "manual" derivative mode (always used on nv50 and sometimes on nvc0
but always for cube), the idea is that using the quadop instruction, we
set up the "other" quads to have values such that the derivatives work
out, and then run the texture instruction as if nothing were strange. It
pulls values from the other lanes, and does its magic.

However cube coordinates have to be normalized - one of the 3 coords has
to be 1, to determine which is the major axis, to say which face is
being sampled. We were normalizing the coordinates first, and then
adding the derivatives. This is wrong for two reasons:

- the coordinates got normalized by a scaling factor but the
  derivatives didn't
- the result of the addition didn't end up normalized

To resolve this, we flip the logic around to normalize *after* the
per-lane coordinates are set up.

This fixes a bunch of textureGrad cube dEQP tests.

NOTE: nv50 cube arrays with explicit derivatives are still broken, to be
resolved at a later date.

egl: support EGL_LARGEST_PBUFFER in eglCreatePbufferSurface(...)

EGL_LARGEST_PBUFFER is used by the client. MIN2 macro is moved

From EGL 1.5 spec:
   "Use EGL_LARGEST_PBUFFER to get the largest available pbuffer
   when the allocation of the pbuffer would otherwise fail."

Currently there exists no API to query largest available pixmap size
using xlib or xcb so right now this seems most straightforward way to
ensure that we fulfill above API and also we don't attempt to allocate
'too big' pixmap which might succeed on server side but not work in
practice when driver starts to use it as a texture.

8 years agoglsl: disable varying packing when its not safe
Timothy Arceri [Mon, 29 Feb 2016 00:46:37 +0000 (11:46 +1100)]
glsl: disable varying packing when its not safe

In GL 4.4+ there is no guarantee that interpolation qualifiers will
match between stages so we cannot safely pack varyings using the
current packing pass in Mesa.

We also disable packing on outerward facing interfaces for SSO
because in ES we need to retain the unpacked varying information
for draw time validation. For desktop GL we could allow packing for
SSO in versions < 4.4 but its just safer not to do so.

We do however enable packing on individual arrays, structs, and
matrices as these are required by the transform feedback code and it
is still safe to do so.

Finally we also enable packing when a varying is only used for
transform feedback and its not a SSO.

This fixes all remaining rendering issues with the dEQP SSO tests,
the only issues remaining with thoses tests are to do with validation.

Note: There is still one remaining SSO bug that this patch doesn't fix.
Their is a chance that VS -> TCS will have mismatching interfaces
because we pack VS output in case its used by transform feedback but
don't pack TCS input for performance reasons. This patch will make the
situation better but doesn't fix it.

V4: fix out of order function params after rebase, make sure packing
still disabled in tess stages. Update comments as to why we disable
packing on SSO.

V3: ES 3.1 *does* require interpolation to match so don't disable
packing there. Rebased on master rather than on enhanced layouts
component packing series.

V2: Make is_varying_packing_safe() a function in the varying_matches
class, fix spelling (Matt) and make sure to remove the outer array
when dealing with Geom and Tess shaders where appropriate.
Lastly fix piglit regression in new piglit test and document the
undefined behaviour it depends on:
