* gpu: nvgpu: Remove vmalloc.h and slab.h usageAlex Waterman2017-04-04
| | | | | | | | | | | | | | Remove all usage of vmalloc.h and slab.h outside of the Linux specific kmem API implementation code.

* gpu: nvgpu: debugging API updateAlex Waterman2017-04-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the debugging APIs in nvgpu to be more coherent and less dependent on Linux kernel APIs and data structures. The old API is maintained for backwards compatibility but the prints themselves are changed. The old API now prints stuff like this: [ 46.376077] nvgpu: gk20a_channel_suspend:3430 [DBG] suspend channel 508 [ 46.376242] nvgpu: gk20a_channel_suspend:3430 [DBG] suspend channel 509 [ 46.376359] nvgpu: gk20a_channel_suspend:3430 [DBG] suspend channel 510 [ 46.376466] nvgpu: gk20a_channel_suspend:3430 [DBG] suspend channel 511 [ 46.376604] nvgpu: gk20a_fifo_update_runlist_locked:3090 [DBG] runlist_id : 0, switch to new buffer 0x 4003a0000 [ 46.378348] nvgpu: gk20a_mm_l2_flush:5259 [DBG] l2_flush_dirty 0x2 [ 46.378562] nvgpu: clk_config_pll:170 [DBG] low_PL 1(div1), high_PL 2(div2) [ 46.378684] nvgpu: clk_config_pll:170 [DBG] low_PL 8(div8), high_PL 17(div17) Each line starts with 'nvgpu:' since this is the nvgpu driver. Then there's the function name which is is right justified and post-fixed with a line number. This keeps all statements lined up so long as the function name does not exceed the length of characters alloted for function names (33 currently). Lines are also left justified with 4 available spaces since there are currently no source files with over 9999 lines. The type of message (DBG, WRN, ERR) is then printed in brackets. Finally there's whatever message is to be printed. The new API will be largely the same except there will be an additional print of the GPU that the message has originated from in order to help debug cases where both an iGPU and dGPU are active. Also the implicit newline added in the legacy API has been removed. This is inline with essentially every other print function in the C world. There are numerous places where '\n' is added despite it not being needed which results in log files being littered with blank lines. This makes the logs much harder to read. Bug ...

* gpu: nvgpu: Move programming of host registers to fifoTerje Bergstrom2017-03-28
| | | | | | | | | | | | | | | | | | | Move code that touches host registers and instance block to fifo HAL. This involves adding HAL ops for the fifo HAL functions that get called from outside fifo. This clears responsibility of channel by leaving it only managing channels in software and push buffers. channel had member ramfc defined, but it was not used, to remove it. pbdma_acquire_val consisted both of channel logic and hardware programming. The channel logic was moved to the caller and only hardware programming was moved.

* gpu: nvgpu: Remove circular dependency in PMU includesTerje Bergstrom2017-01-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove including gk20a.h from pmu_gk20a.h. This causes a fallout as some #includes were missing. gr_gp10b.h uses mem_desc, but did not include mm_gk20a.h. Add the include. Including mm_gk20a.h in gr_gp10b.h causes recursive include, as mm_gk20a.h has some gr defines. Move the defines to gr_gk20a.h to remove the dependency. gr_ctx_gk20a.h used struct gk20a pointers, but did not forward declare it. Add a forward declaration. gr_gk20a.h uses dbg_session_gk20a, but was missing forward declaration. gr_gk20a.h did not include nvgpu.h but it uses preemption types from that header. Add include.
