* gpu: nvgpu: gv11b: disable fifo_intr_0_runlist_eventSeema Khowala2018-01-11
| | | | | | | | | | | | | | | | | | | | | | runlist event interrupt is not needed to be enabled as s/w polls for preemption completion for preempts issued in RUNLIST_PREEMPT. Even though it is not enabled, intr will get set in fifo_intr_0 status register whenever RUNLIST_PRREMPT is successfully completed. Since intr is disabled, fifo intr will not be triggered but it will be handled during handling of other fifo interrupts whenever fifo intr is triggered.

Use TEGRA_VGPU_CMD_GET_SMS_MAPPING to query current mapping.

* gpu: nvgpu: gv11b: fix for gfx preemptionseshendra Gadagottu2018-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Used chip specific attrib_cb_gfxp_default_size and attrib_cb_gfxp_size buffer sizes during committing global callback buffer when gfx preemption is requested. These sizes are different for gv11b from gp10b. For gp10b used smaller buffer sizes than specified value in hw manuals as per sw requirement. Also used gv11b specific preemption related functions: gr_gv11b_set_ctxsw_preemption_mode gr_gv11b_update_ctxsw_preemption_mode This is required because preemption related buffer sizes are different for gv11b from gp10b. More optimization will be done as part of NVGPU-484. Another issue fixed is: gpu va for preemption buffers still needs to be 8 bit aligned, even though 49 bits available now. This done because of legacy implementation of fecs ucode.
