* gpu: nvgpu: Remove Linux devnode fields from gk20aTerje Bergstrom2017-06-21
| | | | | | | | | | | | | | | Move Linux devnode related fields to a new header file os_linux.h. The class structure is defined in module.c, so move its declaration to module.h.

* gpu: nvgpu: hal for timestamps correlationThomas Fleury2017-06-15
| | | | | | | | | | | | | | | | | | | | | | | | In order to perform timestamps correlation for FECS traces, we need to collect GPU / GPU timestamps samples. In virtualization case, it is possible for a guest to get GPU timestamps by using read_ptimer. However, if the CPU timestamp is read on guest side, and the GPU timestamp is read on vm-server side, then it introduces some latency that will create an artificial offset for GPU timestamps (~2 us in average). For better CPU / GPU timestamps correlation, Added a command to collect all timestamps on vm-server side.

* gpu: nvgpu: remove duplicate \n from log messagesStephen Warren2017-05-26
| | | | | | | | | | | | | | | nvgpu_log/info/warn/err() internally add a \n to the end of the message. Hence, callers should not include a \n at the end of the message. Doing so results in duplicate \n being printed, which ends up creating empty log messages. Remove the duplicate \n from all err/warn messages.

* gpu: nvgpu: Put debugfs dependencies inside #ifdefTerje Bergstrom2017-04-24
| | | | | | | | | | | | | | | | | | | Put all debugfs dependencies inside #ifdef CONFIG_DEBUG_FS. This includes some functions in allocators that were used only for debugging. Remove include of linux/debugfs.h on files that do not deal with debugfs. linux/debugfs.h implicitly included linux/fs.h, which we relied on. Add explicit include of linux/fs.h for all files where this is the case.
