* gpu: nvgpu: gv11b: fifo recovery for nonreplay faultSeema Khowala2017-07-08
| | | | | | | | | | | | | | | | Host will no longer receive replayable or non-replayable fault requests. MMU will handle both types of fault reporting. This means that Host will no longer automatically disable scheduling or preempt a PBDMA when an engine page faults. After fault happens, engine will stall on its own fault and will not context switch until the fault is serviced JIRA GPUT19X-7 Change-Id: I8039e6f50d87f43e101d1372faa5ca6fb739036e Signed-off-by: Seema Khowala <seemaj@nvidia.com> Reviewed-on: https://git-master/r/1493417 Reviewed-by: Vijayakumar Subbu <vsubbu@nvidia.com> GVS: Gerrit_Virtual_Submit

One for copying from fault snap registers/nonreplayable h/w fault buffers and one for replay h/w fault buffers -implement s/w set up for buffering mmu faults Replayable/Non-replayable fault buffers are mapped in BAR2 virtual/physical address space. These buffers are circular buffers in terms of address calculation. Currently there are num host channels buffers -configure h/w for buffering mmu faults if s/w set up is successful, configure h/w registers to enable buffered mode of mmu faults -if both s/w and h/w set up are successful, enable corresponding hub interrupts -implement new ops, fault_info_buf_deinit This will be called during gk20a_mm_destroy to disable hub intr and de-allocate shadow fault buf that is used to copy mmu fault info during mmu fault handling -implement mm ops remove_bar2_vm This will also unmap and free fault buffers mapped in BAR2 if fault buffers were allocated JIRA GPUT19X-7 JIRA GPUT19X-12 Change-Id: I53a38eddbb0a50a1f2024600583f2aae1f1fba6d Signed-off-by: Seema Khowala <seemaj@nvidia.com> Reviewed-on: https://git-master/r/1492682 Reviewed-by: Vijayakumar Subbu <vsubbu@nvidia.com> GVS: Gerrit_Virtual_Submit
