Hi all,
The below patch fixes a recently introduced failure of my VAO rework.
I could finally reproduce the problem using the provided apitrace
(thanks Kai for the hint with the lower left corner).
The change is slightly different than what I put initially into the
bugreport.
The patch survived piglit quick and dEQP in radeonsi and did not
introduce regressions to the base version with intels CI system.
Please review!
best
Mathias
The recent patch
mesa: Remove FLUSH_VERTICES from VAO state changes.
Pending draw calls on immediate mode or display list calls do
not depend on changes of the VAO state. So, remove calls to
FLUSH_VERTICES and flag _NEW_ARRAY as appropriate.
uncovered a problem that non immediate mode draw calls do only
flush outstanding immediate mode draws if FLUSH_UPDATE_CURRENT
is set in ctx->Driver.NeedFlush.
In that case, due to the sequence of _mesa_set_draw_vao commands
we could end up with the VAO from the FLUSH_VERTICES call set
into gl_context::Array._DrawVAO when the array draw is executed.
So the change pulls FLUSH_CURRENT out of _mesa_validate_* calls
into the array draw calls being validated.
The change introduces a new macro FLUSH_FOR_DRAW beside FLUSH_VERTICES
and FLUSH_CURRENT that flushes on changed current attributes as well
as on outstanding immediate mode draw calls. Use FLUSH_FOR_DRAW
in the non immediate mode draw code paths.
