* 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: support binding multiple channels to a debug sessionDeepak Nibade2016-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently bind only one channel to a debug session But some use cases might need multiple channels bound to same debug session Add this support by adding a list of channels to debug session. List structure is implemented as struct dbg_session_channel_data List node dbg_s_list_node is currently defined in struct dbg_session_gk20a. But this is inefficient when we need to add debug session to multiple channels Hence add new reference structure dbg_session_data to store dbg_session pointer and list entry For each NVGPU_DBG_GPU_IOCTL_BIND_CHANNEL call, create two reference structure dbg_session_channel_data for channel and dbg_session_data for debug session and bind them together Define API nvgpu_dbg_gpu_get_session_channel() which will get first channel in the list of debug session Use this API wherever we refer to channel bound to debug session Remove dbg_sessions define in struct gk20a since it is not being used anywhere Add new API NVGPU_DBG_GPU_IOCTL_UNBIND_CHANNEL to support unbinding of channel from debug sesssion Bug 200156699 Change-Id: I3bfa6f9cd5b90e7254a75c7e64ac893739776b7f Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1120331 GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>
