A recent commit means igt_debugfs.c now needs to include igt_kms.h,
which in turn includes igt_fb.h and hence cairo.h.
We need to avoid this inclusion of cairo.h when building for Android,
(until we have a cairo port) so I have added a #ifndef around it.

In android builds there is no reliable way to determine if mmap64 is defined
or not, and this sometimes leads to a compile error due to its re-defnition.
So this commit avoids its use altogether in intel-gpu-tools for Android builds,
unless the HAVE_MMAP64 macro is defined.

Someone with actual automake-fu really needs to fix this up for real
since compiling a bunch of source files again, with broken dep

isn't too awesome.

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.

Using uint64_t in that second member makes it aligned to 64bits, while
the first member is only 32bits. We then had a 32bits hole in there!

For 1 function and 2 types we kinda don't need separate files.
Especially now that igt_kms is much more focused on the actual modeset
stuff with all the framebuffer helpers extracted to igt_fb.

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>
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.

quick_dump built fine, but it could actually run, since a lot of the
linking happens at run time. There is one hack where we redefine the
environment stuff, since depending on igt_aux means we have to pull in
libdrm, which I do not want to do.

I've forgotten that we might want to call this from within specific

Also rename the arguments of do_ioctl a bit for better clarity.

So I wasn't really happy with env_set since it's way too close to
