2011-11-30video: tegra: nvhost: add submit timeout supportChris Johnson
In this change, nvhost_cdma starts a timer (if a timeout is specified in the userctx), for the buffer at the head of the sync_queue that has not reached its syncpt threshold. If the timeout fires, nvhost_cdma initiates a channel / module reset. It then detects up to where in the sync_queue it stopped execution (based on the current HW syncpt value). For any remaining uncompleted buffers in the context, nvhost_cdma NOPs the entry and CPU incrs the syncpt to where it should be had it completed. If one of the sync_queue entries belongs to another context, it still does the syncpt incrs for this context, but via the PB as a GATHER opcode, At the end, CDMA is restarted, so buffers are refetched (either with NOP slots, or GATHERs to incr syncpts). This appears as though the buffer has completed (and the associated resources released). For testing, debugfs entries have been added under /d/tegra_nvhost force_timeout_val - set the timeout value, in ms force_timeout_channel - channel ID, were timeouts checks occur force_timeout_pid - process ID to set the userctx The idea is to set the timeout_val, then the timeout_channel (e.g. for 3D, the channel ID is 1) and then the process ID, gotten from running adb shell ps.
