There is HW specific limit on number of channel entries that can be added for each TSG entry in runlist. Right now there is no checking to enforce this from SW and hence if User binds more than supported channels to same TSG, invalid TSG formation error interrupts are generated. Fix this by adding appropriate checks in below steps : - Add new field ch_count to struct nvgpu_tsg to keep track of channels bound to TSG. - Define new hal gops.runlist.get_max_channels_per_tsg() to retrieve HW specific maximum channel count per TSG. - Implement the HAL for gk20a and gv11b chips, and assign new HALs for all chips appropriately. - Increment ch_count while binding the channel to TSG and decrement it while unbinding. - While binding channel to TSG, Check if current channel count is already equal to max channel count. If yes, print an error and bail out.
