2016-10-18drmtest: Install exithandler for i915, even in multidriver testsChris Wilson
If we opened the driver multiple times, we would not flush i915 if it was opened second. The persistence of one test state into a second can upset third parties, e.g. prime_vgem upsetting vgem_basic (due to references from i915.ko to vgem.ko preventing module unload).

2016-10-13lib/igt_aux: Add support for various system suspend/resume optionsImre Deak
To have a more accurate idea about any suspend/resume issues we can perform the s/r until various phases in the s/r sequence. This way we can isolate the given problem as being a device driver, kernel core or BIOS related issue. Actual subtests using these new s/r phases will be added as follow-up. While at it also add the freeze suspend target, it's something we also would need to test. Signed-off-by: Imre Deak <imre.deak@intel.com>
2016-10-13lib/igt_gt: Use /sys/.../error instead of /debug/.../i915_error_stateChris Wilson
The stable path is via sys, but we only have to use this should the kernel be ignoring our request to ignore simulated hangs. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-10-13igt/gem_wait: Use explicit timersChris Wilson
Rather than guestimating a workload that should take a certain amount of time, use a sigitimer to terminate a batch (and so complete the wait) after an exact amount of time. And in the process expand testing to cover multiple rings and hangcheck. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2016-09-16lib: Add an iterator to generate primesChris Wilson
Primes are useful as input sources since they should not fall into any patterns that may be optimised by the drivers. An example of use this in a test driver: uint32_t seqno, inc, count; seqno = inc = count = 0; do { inc = igt_next_prime_number(inc); if (seqno + inc < seqno) break; seqno += inc; /* igt_assert_eq(test_inc(inc), seqno); */ count++; } while (1); printf("count=%u, seqno=%u, last=%u\n", count, seqno, inc); and prints "count=27878, seqno=4294845817, last=323381", or for simply generating the set of the first N prime numbers, use for_each_prime_number(prime, 100) printf("%lu ", prime); which prints 1 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 64 67 71 73 79 83 89 97 101 103 107 109 113 127 131 137 139 149 151 157 163 167 173 179 181 191 193 197 199 211 223 227 229 233 239 241 251 257 263 269 271 277 281 283 293 307 311 313 317 331 337 347 349 353 359 367 373 379 383 389 397 401 409 419 421 431 433 439 443 449 457 461 463 467 479 487 491 499 503 509 521 Note that 1 is included in the set of prime numbers for convenience above. Mathematicians beware! The set of primes is computed using the Sieve of Eratosthenes, which basically just keeps a list of all multiples - any number not in list is therefore prime. As a bitmask of all integers is kept, it can be quite memory intensive for very large primes. A fallback to "trial division" is available just in case, but for large primes that is much slower.

2016-09-01autotools/: Allow check target to be invoked w/o the need to issue a build.Marius Vlad
We need to have the test list generated before running the check target. Migrated igt_command_line.sh to tests/ from lib/tests/, which allows to building the tests and execute the script. This would allow cleaning followed by a make check. Also assembler/ directory needs also to be adjusted in order for this to work.

2016-08-04lib/stubs: Add stubs for intel_bufmgrRobert Foss
This patch provides stubs for functionality otherwise provided by intel_bufmgr. The stubbed functions all fail with a call to igt_require_f(false,""). Defines and enums have been copied from libdrm_intel. Due to the stubbed tests failing with an igt_require_f() call, these stubs are not well suited for non-tests, since tools/benchmarks/etc 'skipping' execution is unhelpful.
