* gpu: nvgpu: posix: Multithreading for unit testsNicolas Benech2018-09-27
| | | | | | | | | | | | | | | | | | Add a -j argument to enable running unit tests on several threads. Also adds signal handling to prevent a fatal error in one thread from killing the whole unit test framework.

* gpu: nvgpu: unit: deref twice in qsort callbackKonsta Holtta2018-09-18
| | | | | | | | | | | | | | | | | | The compare function for qsort takes pointers to compared elements, and our elements are already pointers so the void pointer has to be cast to a pointer pointer. Dereferencing only once would compare some data that's in the array of module pointers (or past it), not the actual data where the module pointers point to.

* gpu: nvgpu: unit: Sort unit tests by priorityAlex Waterman2018-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sort unit tests by their priority before running said unit tests. There are three available priorities: UNIT_PRIO_SELF_TEST UNIT_PRIO_POSIX_TEST UNIT_PRIO_NVGPU_TEST Which correspond to the types of testing expected to be run. In general unit tests should always just use UNIT_PRIO_NVGPU_TEST but in the case of tests for the POSIX API layer or the unit test framework the other two priorities are provided. The reason for this is that it doesn't make much sense to run a bunch of unit tests if the environment itself or the POSIX API layer is broken. By placing these tests at the front of the list of tests to run an engineer will easily be able to see if there are core problems versus nvgpu problems. This also lets users fine grain control of test order by adding or subtracting to UNIT_PRIO_NVGPU_TEST but one must be very careful about how they do this.

* gpu: nvgpu: Userspace POSIX supportAlex Waterman2018-05-07
Add support for compiling nvgpu in a POSIX compliant userspace. This code adds all of the necessary abstraction interfaces (mostly stubbed) to enabled extremely limited and basic functionality in nvgpu. The goal of this code is to facilitate unit testing of the nvgpu common core. By doing this in userspace it is much easier to write tests that rely on very particular states within nvgpu since a user can very precisely control the state of nvgpu.
