gpu: nvgpu: support storing/reading single SM error state
Add support to store error state of single SM before preprocessing SM exception Error state is stored as : struct nvgpu_dbg_gpu_sm_error_state_record { u32 hww_global_esr; u32 hww_warp_esr; u64 hww_warp_esr_pc; u32 hww_global_esr_report_mask; u32 hww_warp_esr_report_mask; } Note that we can safely append new fields to above structure in the future if required Also, add IOCTL NVGPU_DBG_GPU_IOCTL_READ_SINGLE_SM_ERROR_STATE to support reading SM's error state by user space Bug 200156699 Change-Id: I9a62cb01e8a35c720b52d5d202986347706c7308 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1120329 GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>
