|
|
|
|
|
[-s | stress ]
|
|
|
|

|
|
|
|
Options:
|
|
|
|
|
The following options can be used:
|
|
|
|
|
-n | --nominal nominal test, runs by default
|
|
|
|
|
-a | --adversarial adversarial test
|
|
|
|
|
-r | --repeatability iterations repeatability test, runs 10
|
|
|
|
|
iterations by default
|
|
|
|
|
-s | --stress stress test
|
|
|
|
|
--source trace_source trace source, supported
|
|
|
|
|
trace_source values are 'etm'
|
|
|
|
|
and 'stm'
|
|
|
|
|
|
|
|
|
|
Requirement:
|
|
|
|
|
CoreSight ETM and STM sources are initially disabled before running any test.
|
|
|
|
|
|
|
|
|
|
Description:
|
|
|
|
|
Nominal Test:
|
|
|
|
|
All CoreSight tests are invoked.
|
|
|
|
|
|
|
|
|
|
Adversarial Test:
|
|
|
|
|
Runs cs_adversary.sh. This test enables all trace sources, all ftrace events and
|
|
|
|
|
toggles the cpu cores on/off.
|
|
|
|
|
|
|
|
|
|
Repeatability Tests:
|
|
|
|
|
All test cases except probe test are invoked for user specified number of iterations,
|
|
|
|
|
or for 10 iterations by default.
|
|
|
|
|
|
|
|
|
|
Stress Test:
|
|
|
|
|
All test cases except probe test are invoked for 100 iterations.
|
|
|
|
|
|
|
|
|
|
Test case description:
|
|
|
|
|
1. platform/platform.sh
|
|
|
|
|
Tests that CoreSight trace drivers are probed without failures.
|
|
|
|
|
|
|
|
|
|
2. etm/etm_enable.sh
|
|
|
|
|
Tests ETM tracing gets properly enabled.
|
|
|
|
|
|
|
|
|
|
3. etm/etm_disable.sh
|
|
|
|
|
Tests ETM tracing get properly disabled.
|
|
|
|
|
|
|
|
|
|
4. stm/stm_enable.sh
|
|
|
|
|
Tests STM tracing gets properly enabled.
|
|
|
|
|
|
|
|
|
|
5. stm/stm_disable.sh
|
|
|
|
|
Tests STM tracing gets properly disabled.
|
|
|
|
|
|
|
|
|
|
6. stm/stm_etf_dump.sh
|
|
|
|
|
Tests ETF can be dumped with good data while STM is the only trace source. All ftrace,
|
|
|
|
|
hardware events are disabled while single string data is sent over STM. Once trailing
|
|
|
|
|
zeros of output file are truncated, size is compared with reference size for same
|
|
|
|
|
input data.
|
|
|
|
|
|
|
|
|
|
7. stm/stm_etr_dump.sh
|
|
|
|
|
Please refer to stm/stm_etf_dump.sh. Here ETR is the trace sink instead of ETM.
|
|
|
|
|
|
|
|
|
|
8. mult_trace/mult_source_enable.sh
|
|
|
|
|
Tests that multiple CoreSight trace sources (ETM and STM) can be successfully enabled
|
|
|
|
|
at the same time.
|
|
|
|
|
|
|
|
|
|
9. mult_trace/mult_source_disable.sh
|
|
|
|
|
Tests that multiple CoreSight trace sources (ETM and STM) can be successfully disabled
|
|
|
|
|
at the same time.
|
|
|
|
|
|
|
|
|
|
10. sink_switch/sinkswitch.sh
|
|
|
|
|
Tests that the device can switch between multiple CoreSight tracesinks. Assumes etf,
|
|
|
|
|
etr and tpiu sinks are present.
|
|
|
|
|
|
|
|
|
|
11. sink_switch/etr_modes.sh
|
|
|
|
|
Tests that the modes of ETR can be changed from usb to memory and vice versa.
|
|
|
|
|
|
|
|
|
|
12. cs_adversary.sh
|
|
|
|
|
While having trace sources enabled, enables and disables all cores in a loop.
|
|

|
13. profile/cs_profile.sh
|
|
|
|
|
This test enables STM tracing and echoes fixed amount of data(4KB) over stm. It
|
|
|
|
|
calculates the time taken to send that data.
|
|
|
|
|
|
|
|
|
|
14. byte-cntr/byte_cntr.sh
|
|
|
|
|
Enables the byte counter feature and tests if data can be streamed to a file
|
|
|
|
|
using the feature. Sends 2MB of data and checks if the data collected is
|
|
|
|
|
greater than the sent data. Target supported: 8x26

|
|
All tests prints:
|
