* gpu: nvgpu: Move Linux nvgpu_mem fieldsAlex Waterman2017-04-20
| | | | | | | | | | | | | | | | | | | | Hide the Linux specific nvgpu_mem fields so that in subsequent patches core code can instead of using struct sg_table it can use mem_desc. Routines for accessing system specific fields will be added as needed. This is the first step in a fairly major overhaul of the GMMU mapping routines. There are numerous issues with the current design (or lack there of): massively coupled code, system dependencies, disorganization, etc. JIRA NVGPU-12 JIRA NVGPU-30 Change-Id: I2e7d3ae3a07468cfc17c1c642d28ed1b0952474d Signed-off-by: Alex Waterman <alexw@nvidia.com> Reviewed-on: http://git-master/r/1464076 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Give nvgpu_kalloc a less generic nameAlex Waterman2017-03-03
| | | | | | | | | | | | | | | | | | | | | | Change nvgpu_kalloc() to nvgpu_big_[mz]alloc(). This is necessary since the natural free function name for this is nvgpu_kfree() but that conflicts with nvgpu_k[mz]alloc() (implemented in a subsequent patch). This API exists becasue not all allocation sizes can be determined at compile time and in some cases sizes may vary across the system page size. Thus always using kmalloc() could lead to OOM errors due to fragmentation. But always using vmalloc() is wastful of memory for small allocations. This API tries to alleviate those problems.
