* gpu: nvgpu: Move Linux kernel driver code to module.cTerje Bergstrom2017-04-18
| | | | | | | | | | | | | | | | Move Linux driver specific code to common/linux/module.c. This includes module initialization, power management, and interrupt functions. Move pci.c, pci.h and nvgpu_common.c under common/linux as they're Linux only files.

Use PCI vendor/device ids and VBIOS version to identify such device, and set power_sensor_missing flag. This flag is subsequently used to skip power device and power policy programming in PMU.

* gpu: nvgpu: Fix submit profiling stat reportingPeter Boonstoppel2017-04-17
| | | | | | | | | | | | | | | | | | | The debugfs submit profiling stats report the distribution of submit times at different percentiles. The original code reports the lowest entry in every percentile-bin as being representative for that bin. This means that where debugfs reports the 50th percentile, it actually reports the ~45.001th percentile. This is especially inconveniant when looking at the 100th percentile, which does not in fact reflect the maximum. This patch changes the code to instead report the highest entry in every percentile-bin.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 ...
