* 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.

* gpu: nvgpu: Fix address space limit computationAlex Waterman2015-07-20
| | | | | | | | | | | | | | | | | | | | | | The address space limit was being computed with the assumption that the va_limit field is inclusive. The va_limit field is actually not inclusive. It points to the first invalid byte. Thus when generating the adr_limit register the code incorrectly calculated that the address limit should be 0. To fix this the computation now just uses va_limit - 1. Also, the bitwise OR of 0xfff into the lower limit word was incorrect. The bottom 12 bits of the lower 32 bit word are ignored by the GPU and as such should not be populated.

* gpu: nvgpu: WAR for bad GPFIFO entries from userspaceAlex Waterman2015-06-11
| | | | | | | | | | | | | | | | | | Userspace sometimes sends GPFIFO entries with a zero length. This is a problem when the address of the pushbuffer of zero length is larger than 32 bits. The high bits are interpreted as an opcode and either triggers an operation that should not happen or is trated as invalid. Oddly, this WAR is only necessary on simulation.

* 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.
