| * @PORTAL_CMD_GET_CLK_RATE_MGR: Request the clock trace manager internal |
| * data record. On a positive acknowledgement |
| * the prevailing clock rates and the GPU idle |
| * condition flag are returned. |
| * @PORTAL_CMD_GET_CLK_RATE_TRACE: Request the clock trace portal to return its |
| * data record. On a positive acknowledgement |
| * the last trace recorded clock rates and the |
| * GPU idle condition flag are returned. |
| * @PORTAL_CMD_GET_TRACE_SNAPSHOT: Request the clock trace portal to return its |
| * current snapshot data record. On a positive |
| * acknowledgement the snapshot array matching |
| * the number of clocks are returned. It also |
| * starts a fresh snapshot inside the clock |
| * trace portal. |
| * @PORTAL_CMD_INC_PM_CTX_CNT: Request the clock trace portal to increase |
| * its internal PM_CTX_COUNT. If this increase |
| * yielded a count of 0 -> 1 change, the portal |
| * will initiate a PM_CTX_ACTIVE call to the |
| * Kbase power management. Further increase |
| * requests will limit to only affect the |
| * portal internal count value. |
| * @PORTAL_CMD_DEC_PM_CTX_CNT: Request the clock trace portal to decrease |
| * its internal PM_CTX_COUNT. If this decrease |
| * yielded a count of 1 -> 0 change, the portal |
| * will initiate a PM_CTX_IDLE call to the |
| * Kbase power management. |
| * @PORTAL_CMD_CLOSE_PORTAL: Inform the clock trace portal service the |
| * client has completed its session. The portal |
| * will start the close down action. If no |
| * error has occurred during the dynamic |
| * interactive session, an inherent basic test |
| * carrying out some sanity check on the clock |
| * trace is undertaken. |
| * @PORTAL_CMD_INVOKE_NOTIFY_42KHZ: Invokes all clock rate trace manager callbacks |
| * for the top clock domain with a new GPU frequency |
| * set to 42 kHZ. |
| * @PORTAL_CMD_INVALID: Valid commands termination marker. Must be |
| * the highest enumeration value, as it |
| * represents valid command array size. |
| * @PORTAL_TOTAL_CMDS: Alias of PORTAL_CMD_INVALID. |

| * DOC: Portal service request command names. |
| * |
| * The portal request consists of a kutf named u64-value. |
| * For those above enumerated PORTAL_CMD, the names defined |
| * here are used to mark the name and then followed with a sequence number |
| * value. Example (manual script here for illustration): |
| * exec 5<>run # open the portal kutf run as fd-5 |
| * echo GET_CLK_RATE_MGR=1 >&5 # send the cmd and sequence number 1 |
| * head -n 1 <&5 # read back the 1-line server response |
| * ACK="{SEQ:1, RATE:[0x1ad27480], GPU_IDLE:1}" # response string |
| * echo GET_TRACE_SNAPSHOT=1 >&5 # send the cmd and sequence number 1 |
| * head -n 1 <&5 # read back the 1-line server response |
| * ACK="{SEQ:1, SNAPSHOT_ARRAY:[(0x0, 0x1ad27480, 1, 0)]}" |
| * echo CLOSE_PORTAL=1 >&5 # close the portal |
| * cat <&5 # read back all the response lines |
| * ACK="{SEQ:1, PM_CTX_CNT:0}" # response to close command |
| * KUTF_RESULT_PASS:(explicit pass) # internal sanity test passed. |
| * exec 5>&- # close the service portal fd. |
| * |
| * Expected request command return format: |
| * GET_CLK_RATE_MGR: ACK="{SEQ:12, RATE:[1080, 1280], GPU_IDLE:1}" |
| * Note, the above contains 2-clock with rates in [], GPU idle |
| * GET_CLK_RATE_TRACE: ACK="{SEQ:6, RATE:[0x1ad27480], GPU_IDLE:0}" |
| * Note, 1-clock with rate in [], GPU not idle |
| * GET_TRACE_SNAPSHOT: ACK="{SEQ:8, SNAPSHOT_ARRAY:[(0x0, 0x1ad27480, 1, 0)]}" |
| * Note, 1-clock, (start_rate : 0, last_rate : 0x1ad27480, |
| * trace_rate_up_count: 1, trace_rate_down_count : 0) |
| * For the specific sample case here, there is a single rate_trace event |
| * that yielded a rate increase change. No rate drop event recorded in the |
| * reporting snapshot duration. |
| * INC_PM_CTX_CNT: ACK="{SEQ:1, PM_CTX_CNT:1}" |
| * Note, after the increment, M_CTX_CNT is 1. (i.e. 0 -> 1) |
| * DEC_PM_CTX_CNT: ACK="{SEQ:3, PM_CTX_CNT:0}" |
| * Note, after the decrement, PM_CTX_CNT is 0. (i.e. 1 -> 0) |
| * CLOSE_PORTAL: ACK="{SEQ:1, PM_CTX_CNT:1}" |
| * Note, at the close, PM_CTX_CNT is 1. The PM_CTX_CNT will internally be |
| * dropped down to 0 as part of the portal close clean up. |
