I'm not sure if I really got it right. This seems like one of those
"Duh, of course it works that way" things, but I'd like the
documentation to be readable by people not acquainted with OGL/D3D.
Only for first RT at the moment, as there is no trivial way in galahad
to look at framebuffer state and (sadly) people don't usually calloc
their CSOs, so flags could be wrongly set.
On the other hand, of course, galahad will hopefully encourage more
people to calloc their CSOs. :3
We were previously calculating a value which was either the geometry
shader output primitive or the application's input primitive, and
passing that to the various front/middle/back components for use as
the ultimate rendering primtive.
Unfortunately, this was not correct -- if the vcache decomposition
path is active and geometry shaders are *not* active, we can end up
with a third primitive -- specifically the decomposed version of the
input primitive.
Rather than trying to precalculate this, just let the individual
components inform their successors about which primitive type they are
recieving.
Any elt may potentially have flags bits set so mask off those bits
everywhere.
Fixes crashes with demos/gamma.c, redbook/polys.c, etc. but polygon
stippling is still broken.
This commit introduces type-safe platform displays internally. A
platform display consists of a generic pointer and an enum that
specifies the platform.
An EGLDisplay is created from a platform display. Native displays
become platform displays whose platform is determined by
_eglGetNativePlatform(). Platform windows and pixmaps may also be
introduced if needed.
Galahad is a sanity-checking layer meant to replace the crufty and
scattered sanity checks inside drivers with a robust, non-silenceable,
useful set of warnings and errors that can be used to keep misbehaving
state trackers from going unnoticed.
allows application to not only request the frequency of the TIME_ELAPSED
clock but also to detect if that frequency was consistent throughout the
entire bracketed range of graphics commands.
