As we use chained batch into itself to hang the gpu, there
was no need to end the batchbuffer with BATCH_BUFFER_END.
With the introduction of command parser, the batch
need to have proper BATCH_BUFFER_END in it or it
will be rejected.
While at it, shift the upper half of batch gtt_offset
accordingly with gen8+

Note that the sleep(5); to fully idle the gpu is _really_ important.
Without it the bug is not exhibited.
The issue at hand is that after gem_quiescent_gpu we are at max
(expected, since the blocking waits peg to max), but then we never go
down to a lower freq again until we're fully idle. The tiny load is
sufficient to keep the gpu at max. I've played around with this a bit
and even ridiculously low loads (like one MI_STORE per 50ms) are
enough to keep the gpu at max freq.
Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
Apparently some rps chips are prone to stick to max once you're there.
And all the synchronous waits in gem_quiescent_gpu are _really_ good
at forcing the kernel to go full throttle.
And even a positively tiny load (one MI_STORE_IMM per 50 ms) is enough
to eternally keeep it there, which means the first idle measurement of
the freqs before we do the reset it completely busted.
Just add a wait before the tricky test and call it a day.
Option b) would have been to now have this tiny load, but I think a
good reminder how quirky rps is is always welcome. Just in case we
start sleeping too easy at night.

Shorter and more in line with our general igt_ prefix for everything
which isn't somehow intel or i915-gem or otherwise hw specific - these
helpers here are all fully generic framebuffer handling functions
based on kms + cairo.
Well, the actual buffer alloc is done with i915 gem, but meh ;-)
Two special cases:
- bpp_depth_to_drm_format and drm_format_to_bpp completely lacked
prefixes, so just add igt_.
- write_fb was a bit misleading given that we have gem_write for
uploading to buffers. Rename that to write_fb_to_png to make it
crystal clear what this thing does even without looking at docs.
Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
Use the new-style function using drm fourcc codes instead everywhere.
To easily use thew fourcc based interface also expose
bpp_depth_to_drm_format from the library. Finally include drm_fourcc.h
from the igt_kms.h header since pretty much everyone needs this now.

I've forgotten that we might want to call this from within specific
subtests (or special helpers like the autoresume one).
Also props for being competent enough to write a testcase, but
incompetent enough to botch the job up.

Only the igt core and non-test tools should have asserts to catch

I've accidentally broken the new cursor size extensions, but it
wasn't quite correct before already: Variables which are set in
igt_fixtures _must_ be outside of the stackframe of the igt_fixture
block.
Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
Thomas noticed that in simulation mode a lot of the tests fall over
instead of skipping properly. This is due to recently added
self-checks which ensure that any call to igt_skip happens either
within a fixture or subtest block (or it's a simple test without
subtests). This is to catch bugs since pretty much always not wrapping
up hardware setup and checks into these blocks is a bug.
Bug simulation skipping is a bit different, so allow that exception.
Otherwise we'd need to fix up piles of tests (and likely need to play
a game of whack-a-mole).
Also add a library testcase for all the different variants to make
sure it really works.
