Kenneth Graunke 992e2afd59 intel: Change context create failure message to from fprintf to DBG().
Since there is no getparam for hardware context support, Mesa always
tries to obtain a context by calling drm_intel_gem_context_create and
NULL-checking the result.  On an older kernel without context support,
this caused libdrm to print an unwanted message to stderr:

DRM_IOCTL_I915_GEM_CONTEXT_CREATE failed: Invalid argument

In fact, this caused every Piglit test to fail with a "warn" status due
to the unrecognized error message.

Change the message to use DBG() rather than fprintf(), so people can
still get the debug message, but it won't spam normally.

Paul Berry da02f72bc2 intel: Add the ability to supply annotations for .aub files.
This patch adds a new function,
drm_intel_bufmgr_gem_set_aub_annotations(), which can be used to
annotate the type and subtype of data stored in various sections of
each buffer.  This data is used to populate type and subtype fields
when generating the .aub file, which improves the ability of later
debugging tools to analyze the contents of the .aub file.

If drm_intel_bufmgr_gem_set_aub_annotations() is not called, then we
fall back to the old set of annotations (annotate the portion of the
batchbuffer that is executed as AUB_TRACE_TYPE_BATCH, and everything
else as AUB_TRACE_TYPE_NOTYPE).

Eric Anholt 515cea6ac6 intel: Add an interface for removing relocs after they're added.
This lets us replace the current inner drawing loop of mesa:

for each prim {
	compute bo list
	if (check_aperture_space(bo list)) {
		batch_flush()
		compute bo list
		if (check_aperture_space(bo list)) {
			whine_about_batch_size()
			fall back;
		}
	}
	upload state to BOs
}

with this inner loop:

for each prim {
 retry:
	upload state to BOs
	if (check_aperture_space(batch)) {
		if (!retried) {
			reset_to_last_prim()
			batch_flush()
		} else {
			if (batch_flush())
				whine_about_batch_size()
			goto retry;
		}
	}
}

This avoids having to implement code to walk over certain sets of GL
state twice (the "compute bo list" step).  While it's not a
performance improvement, it's a significant win in code complexity:
about -200 lines, and one place to make mistakes related to aperture
space instead of N places to forget some BO we should have included.

Note how if we do a reset in the new loop , we immediately flush.  We
don't need to check aperture space -- the kernel will tell us if we
actually ran out of aperture or not.  And if we did run out of
aperture, it's because either the single prim was too big, or because
check_aperture was wrong at the point of setting up the last
primitive.
