When user space detects an error or does not receive response for a request, Lets do a reset(LDAR) is triggered. Before LDAR, user space sends flush command to the kernel space. In order to debug the cause for this situation and to dump the information, user space sends a dump command to kernel space before sending flush. As a part of this command, it passes the culprit request id and the buffer into which the information can be dumped. Kernel space traverses across the drivers and find the culprit hw and dumps the relevant information in the buffer. This data is written to a file for offline processing. This commit dumps the IFE, CSID registers, LUT tables and context information, cmd buffers, timestamps information for submit, apply, RUP, epoch and buffdones of the last 20 requests.
