gpu: nvgpu: support binding multiple channels to a debug session
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
