lib/igt_core.c: disable lowmemorykiller during tests
Cc: Tim Gore <tim.gore@intel.com>
Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
Several IGT tests cycle through a lot of GEM memory and
when running these tests on Android they tend to get
killed by the lowmemorykiller. The lowmemorykiller really
is not usefull in this context and is just preventing the
test from doing its job. This commit adds a function to
disable the lowmemorykiller by writing "9999" to its
oom adj parameter, which means it will never "select"
any process to kill. The normal linux oom killer is still
there to protect the kernel.
The low memory killer is disabled during the common
init function and then re-enabled by the exit handler.
To make this work for single tests the exit handler is now
installed in the common init function also so that it is
invoked for all tests.
This is just a hack to get round the fact that the i915
driver uses the concept of purgeable memory which is not
understood by the lowmemorykiller. If this ever gets
fixed then this patch can be removed.

[danvet: A bit of polish (coding style, static and rename
check_igt_exit to common_exit_handler, drop the is_disabled check
since we only call this once now).]

With the structured logging it makes more sense to tune this down a
bit. Also, this way it is consistent with Thomas Wood's new activity
indicator helper.
Spotted while discussing Thomas' patch with him.
v2: Thomas noticed that I've forgotten the fflush. Extract
igt_interactive_info for both igt_progress and igt_print_activity.
v3: Interactive output should go to stderr. Also extract the "is this
a terminal" check.

These tests require DRM master right, so make sure they have it from the
beginning. This gives an early indication if another DRM master is running
and makes the given test skip (with a proper explanation of the reason)
instead of exiting with error.

READ(...) is used for Render Target read and Media Block read. But there is no
sampler cache agent on gen9. At the same time two message types don't
share the same cache agent any more. So a parameter is needed for cache agent.
The 2th parameter of read(...) is not used for gen6/gen7/gen8. Hence it is
reused as cache agent for SKL as that on ILK.

Currently tests that use igt_simple_main will simply call
"exit()" if they pass, making it difficult to ensure that
any required cleanup is done. At present this is not an

Due to the nature of the test, we can be reasonably sure that it is
either all copied or not. So we can sacrificing testing the entire
buffer for the expected value in order to speed up the test by only
testing along the diagonal.

Since the last patched value does not match the presumed relocation
value we submit to the kernel, it occasionally makes mistakes. Also note
that the libdrm interface makes the same presumptive mistake, and would
easily be broken by a threaded environment.
