Before, the set_sampler_views() and restore_sampler_views() functions
used MAX2(old,new) to tell the driver how many samplers or sampler
views to set. This could result in cases such as:
pipe->set_fragment_sampler_views(pipe, 4, views={foo, bar, NULL, NULL})
Many/most gallium drivers would take this as-is and set
ctx->num_sampler_views=4 and ctx->sampler_views={foo, bar, NULL, NULL, ...}.
Later, loops over ctx->num_sampler_views would have to check for null
pointers. Worse, the number of sampler views and number of sampler CSOs
could get out of sync:
ctx->num_samplers = 2
ctx->samplers = {foo, bar, ...}
ctx->num_sampler_views = 4
ctx->sampler_views={Foo, Bar, NULL, NULL, ...}
So loops over the num_samplers could run into null sampler_views pointers
or vice versa.
This fixes a failed assertion in the SVGA driver when running the Mesa
engine demo in AA line mode (and possibly other cases).
It looks like all gallium drivers are careful to unreference views
and null-out sampler CSO pointers for the units beyond what's set
with the pipe::bind_x_sampler_states() and pipe::set_x_sampler_views()
functions.
I'll update the gallium docs to explain this as well.
cso: refactor texture sampler and sampler view code2011-02-03T03:28:00ZBrian Paulbrianp@vmware.com2011-02-03T03:19:51Zurn:sha1:c06fa98c86abbff730a098ffbe980347b3c7d0e6
This consolidates the code duplicated between the fragment sampler
and vertex sampler functions. Plus, it'll make adding support for
geometry shader samplers trivial.
cso: rename fragment sampler-related fields2011-02-03T01:14:48ZBrian Paulbrianp@vmware.com2011-02-03T01:14:46Zurn:sha1:5f30e0b2316c5d0a50f1b331e7cdb4c46882e918
To better distinguish from vertex sampler fields.
cso: fix loop bound in cso_set_vertex_samplers()2011-02-03T01:11:30ZBrian Paulbrianp@vmware.com2011-02-03T01:11:27Zurn:sha1:d087cfaabf386c462329fb62f54311523a89f106
Before we were looping to nr_samplers, which is the number of fragment
samplers, not vertex samplers.
NOTE: This is a candidate for the 7.9 and 7.10 branches.

Not all drivers implement this method.
Fixes regression reported by Chris Rankin and bug 28889.
