| | | | | | | | | | | | | | | | | Cyclestats snapshot feature is expected for new devices. The detection code was isolated in separate function and run-time check added to validate/allow ioctl calls on the current GPU.

| | | | | | | | | | | | | | | | | | | | | | | In gk20a_ce2_nonstall_isr(), we first invoke semaphore workqueue on all channels and then clear the interrupt This delay in clearing the interrupt can sometimes lead to dropping of new interrupt If that happens, we never invoke gk20a_channel_semaphore_wakeup() for new semaphore interrupts and semaphore waiting never completes.

* gpu: nvgpu: Check for valid memory pointersYogesh2015-08-12
| | | | | | | | | | | | | | | | | | | | | 1. Before destroying the allocator for PMU dmem check if it was already initialized. It is only initialized through certain paths like PMU ISRs. So while testing the nvgpu module using nvgpu_submit_twod test I found that it was never initialized. 2. Inside gk20a_init_gr_setup_sw, cleanup part calls for de-allocating the already allocated chunk of memory. Whereas, cleanup also gets called when memory allocation inside the same function fails. In such cases, we should have a non-null check else we attempt to free a non-allocated memory and kernel panics.
