Hi,
Because some hardware under some circumstances (e.g. disabled tiling)
may not be able to use a hardware-specific clear path, it would be
nice to let a state tracker do the clearing by drawing a
screen-aligned quad. I am proposing to change the pipe_context->clear
function to return TRUE if buffers were cleared by the driver, and
FALSE if the state tracker should do the clearing by taking a generic
path.
As an example, r300g can use the fast clearing only if colorbuffers
and zbuffers are micro-tiled, otherwise it must draw a screen-aligned
quad and doing it in the driver is really messy.
The attached patch implements this interface change and adapts all
state trackers and drivers.
I noticed that a lot of drivers still use slow util_clear, so they
will greatly benefit from this patch. It's up to their maintainers
whether they enable it, I suspect some unstable drivers may not be
able to draw a quad without visual errors.
Please review.
Best regards
Marek Olšák

Subject: [PATCH] gallium: let drivers fallback on framebuffer clearing
A driver can either clear a framebuffer by itself or can tell the state tracker
to draw a screen-aligned quad if a hardware-specific clear path is not
available.
