* gpu: nvgpu: Prepare for per-GPU CDE program numbersSami Kiminki2015-08-19
| | | | | | | | | | | | | | | Add gpu_ops for CDE, and add get_program_numbers function pointer for determining horizontal and vertical CDE swizzler programs. This allows different GPUs to have their own specific requirements for choosing the CDE firmware programs.

| | | | | | | | | | | | | | | | | | | Add batch support for mapping and unmapping. Batching essentially helps transform some per-map/unmap overhead to per-batch overhead, namely gk20a_busy()/gk20a_idle() calls, GPU L2 flushes, and GPU TLB invalidates. Batching with size 64 has been measured to yield >20x speed-up in low-level fixed-address mapping microbenchmarks.

* gpu: nvgpu: add per-channel refcountingKonsta Holtta2015-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add reference counting for channels, and wait for reference count to get to 0 in gk20a_channel_free() before actually freeing the channel. Also, change free channel tracking a bit by employing a list of free channels, which simplifies the procedure of finding available channels with reference counting. Each use of a channel must have a reference taken before use or held by the caller. Taking a reference of a wild channel pointer may fail, if the channel is either not opened or in a process of being closed. Also, add safeguards for protecting accidental use of closed channels, specifically, by setting ch->g = NULL in channel free. This will make it obvious if freed channel is attempted to be used. The last user of a channel might be the deferred interrupt handler, so wait for deferred interrupts to be processed twice in the channel free procedure: once for providing last notifications to the channel and once to make sure there are no stale pointers left after referencing to the channel has been denied. Finally, fix some races in channel and TSG force reset IOCTL path, by pausing the channel scheduler in gk20a_fifo_recover_ch() and gk20a_fifo_recover_tsg(), while the affected engines have been identified, the appropriate MMU faults triggered, and the MMU faults handled. In this case, make sure that the MMU fault does not attempt to query the hardware about the failing channel or TSG ids. This should make channel recovery more safe also in the regular (i.e., not in the interrupt handler) context.
