* 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: Proper timeout for NVGPU_COND_WAITTerje Bergstrom2017-05-24
| | | | | | | | | | | | | | | | | | The timeout parameter to NVGPU_COND_WAIT() was passed directly to wait_event_timeout(), which takes jiffies. Also allows zero timeout to disable timeout. The return value of NVGPU_COND_WAIT() was defined in a way specific to how Linux wait_event_() calls work. Replace that with proper error reporting and change the callers to check against error codes.

* gpu: nvgpu: add ioctls to get current timesliceThomas Fleury2017-05-24
| | | | | | | | | | | | | | | | | | Add the following ioctls - NVGPU_CHANNEL_IOCTL_GET_TIMESLICE for channel timeslice in us - NVGPU_TSG_IOCTL_GET_TIMESLICE for TSG timeslice in us If timeslice has not been set explicitly, ioctl returns the default timeslice that will be used when programming the runlist entry.

* gpu: nvgpu: common: linux: Use new error macrosTerje Bergstrom2017-04-07
| | | | | | | | | | | | | | | gk20a_err() and gk20a_warn() require a struct device pointer, which is not portable across operating systems. The new nvgpu_err() and nvgpu_warn() macros take struct gk20a pointer. Convert code to use the more portable macros.

* gpu: nvgpu: Remove last Linux kmem usageAlex Waterman2017-04-04
| | | | | | | | | | | | | | | | | | Replace the last of the Linux kmem API usage with nvgpu kmem calls instead. Several places are left alone - allocating the struct gk20a in particular. Also one function was updated in the clk code to take a struct gk20a as an argument so that it could use nvgpu_kmalloc().
