The Broadwell GT3 machine has two independent BSD rings in kernel driver while
it is transparent to the user-space driver. In such case it needs to check
the ring sync between the two BSD rings. At the same time it also needs to
check the sync among the second BSD ring and the other rings.
V2->V3: Follow Imre's comment to remove the unnecessary initialization and
use igt_assert_f instead of igt_assert.
V3->V4: Add gem_multi_bsd_sync_loop.c into the tests/.gitignore

This fills all the gaps we've had in our execbuf testing. Overflow
testing of the various arrays is already done by gem_reloc_overflow.
Also add kms_flip_tiling to .gitignore.
This will cause a bunch of failures since current kernels don't catch
all fallout.

This is an "advanced" form of the the simple gem_render_copy test.
Instead of aiming for maximal simplicity to aide debugging of new
rendercopy backends, this test aims to exercise the execbuf interface

The subsequet code expects the read() to not have filled the entire
buffer, and yet we allow it to do so. Reduce the size passed to read()
by 1 to make the code sane.

The assert in igt_set_stop_rings() is a bit bogus. Suppsoedly it was
meant to assure that the caller always restores the rings to running
state after stopping them. But in its current form it will trigger
any time someone calls the function and the rings were already stopped.
So you can't even restore the rings to running state w/o the assert
triggering.
Fix it up so that it'll ignore the current ring state when we're trying
to restore the rings back to running state.

Test that a page flip from a tiled buffer to a linear one works
correctly. First, it sets the crtc with the linear buffer andr
generate a reference crc for the pipe. Then, the crtc is set with
the tiled one and page flip to the linear one issued. A new crc is
generated and compared to the rerence one.

lib/drmtest: extract rawer __gem_set_tiling
Fix things up so that we properly propaget the error again.
Now to make this all properly work we also need to make kms_flip a
notch more robust against such failures ...
This only blows up on gen2/3 with the pan tests which want a too wide
framebuffer for tiling.

Some tests, namely the close pending variety, tries to
carefully drop all handles to gpu when hang is intruduced,
to expose bugs in reset handling without any clients.
Add guards after and before tests to really know if
the gpu is still alive as the particular test might
report success and then gpu dies few seconds after.

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+

In android builds there is no reliable way to determine if mmap64 is defined

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.

For 1 function and 2 types we kinda don't need separate files.

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.

Stuff all the framebuffer creation, cairo and drm fourcc format
handling in there. This gives us a very clear cut in the headers where
igt_fb.c only needs to include igt_fb.h, and igt_kms.c includes both
(well igt_kms.h pulls in igt_fb.h since we always need this).
The aim here is to add api docs for igt_fb since that part of the kms
library seems fairly stable already, while all the mode setting and
iteration is still a bit in flux.
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.
