* gpu: nvgpu: move pmuif/* to drivers/gpu/nvgpu/include/nvgpuMahantesh Kumbar2017-02-10
| | | | | | | | | | | | | | | | | | Moved pmuif/* headers to drivers/gpu/nvgpu/include/nvgpu folder to support cross platform feature implementation. Made changes to files which accessed “include pmuif/*” to reflect pmuif/* movement changes. Deleted includes of gk20a.h/pmu_gk20a.h from pmuif/*.h files.

* gpu: nvgpu: Skip checking for null in error pathTerje Bergstrom2017-01-26
| | | | | | | | | | | | | | | | | | vfe_var_construct_single_sensed_fuse() first constructs boardobj and then does further validity checks. If the checks fail, it calls exit label. The exit label checks if boardobj is NULL and calls destructor if it is. As there is no path to get to exit label with boardobj NULL, skip the check.

* gpu: nvgpu: Use perf table only if VBIOS supports itTerje Bergstrom2017-01-06
| | | | | | | | | | | | | | | | We retrieve perf table from VBIOS only if respective HAL op is implemented. Later in code we unconditionally dereference a pointer which can lead to NULL pointer access. Fix two new cases by early aborting creation of devinit tables if the perf VBIOS getter is missing.

* gpu: nvgpu: free boardobj if construct hits an errVijayakumar2017-01-05
| | | | | | | | | | | | | | | | | | | During construct of some VFE/CLK boardobjs, some data is filled after a boardobj allocation is done. Free up boardobj memory if an error is encountered in the data filling.
