selftests/ptp: Remove clean target from Makefile

2023-02-13T17:05:49+00:00

Fix the following build warn removing unnecessary clean target from the Makefile. lib.mk handles clean. Makefile:10: warning: overriding recipe for target clean ../lib.mk:124: warning: ignoring old recipe for target clean In addition, fix to use TEST_GEN_PROGS for generated test executables and TES_PROGS for the shell script. Ger rid of all target as lib.mk handles it. Signed-off-by: Shuah Khan

selftests: ptp: Fix incorrect kernel headers search path

2023-02-13T16:09:45+00:00

Use $(KHDR_INCLUDES) as lookup path for kernel headers. This prevents building against kernel headers from the build environment in scenarios where kernel headers are installed into a specific output directory (O=...).

testptp: add option to shift clock by nanoseconds

2022-02-23T01:03:40+00:00

Add option to shift the clock by a specified number of nanoseconds. The new argument -n will specify the number of nanoseconds to add to the ptp clock. Since the API doesn't support negative shifts those needs to be calculated by subtracting full seconds and adding a nanosecond offset.

testptp: set pin function before other requests

2022-01-06T01:08:58+00:00

When the -L option of the testptp utility is specified with other options (e.g. -p to enable PPS output), the user probably wants to apply it to the pin configured by the -L option. Reorder the code to set the pin function before other function requests to avoid confusing users.

testptp: add new options for perout phase and pulse width

2020-07-21T01:04:59+00:00

Extend the example program for PTP ancillary functionality with the ability to configure not only the periodic output's period (frequency), but also the phase and duty cycle (pulse width) which were newly introduced. The ioctl level also needs to be updated to the new PTP_PEROUT_REQUEST2, since the original PTP_PEROUT_REQUEST doesn't support this functionality. For an in-tree testing program, not having explicit backwards compatibility is fine, as it should always be tested with the current kernel headers and sources. Tested with an oscilloscope on the felix switch PHC: echo '2 0' > /sys/class/ptp/ptp1/pins/switch_1588_dat0 ./testptp -d /dev/ptp1 -p 1000000000 -w 100000000 -H 1000 -i 0 Signed-off-by: Vladimir Oltean Acked-by: Richard Cochran Signed-off-by: David S.

testptp: promote 'perout' variable to int64_t

2020-07-21T01:04:59+00:00

Since 'perout' holds the nanosecond value of the signal's period, it should be a 64-bit value. Current assumption is that it cannot be larger than 1 second. Signed-off-by: Vladimir Oltean Acked-by: Richard Cochran Signed-off-by: David S. Miller

ptp: Add adjust_phase to ptp_clock_caps capability.

2020-05-02T23:31:45+00:00

Add adjust_phase to ptp_clock_caps capability to allow user to query if a PHC driver supports adjust phase with ioctl PTP_CLOCK_GETCAPS command. Signed-off-by: Vincent Cheng Reviewed-by: Richard Cochran Signed-off-by: David S. Miller

ptp: Extend the test program to check the external time stamp flags.

2019-11-15T20:48:33+00:00

Because each driver and hardware has different capabilities, the test cannot provide a simple pass/fail result, but it can at least show what combinations of flags are supported. Signed-off-by: Richard Cochran Signed-off-by: David S. Miller

selftests: ptp: Add Physical Hardware Clock test

2019-06-14T05:34:55+00:00

Test the PTP Physical Hardware Clock functionality using the "phc_ctl" (a part of "linuxptp"). The test contains three sub-tests: * "settime" test * "adjtime" test * "adjfreq" test "settime" test: * set the PHC time to 0 seconds. * wait for 120.5 seconds. * check if PHC time equal to 120.XX seconds. "adjtime" test: * set the PHC time to 0 seconds. * adjust the time by 10 seconds. * check if PHC time equal to 10.XX seconds. "adjfreq" test: * adjust the PHC frequency to be 1% faster. * set the PHC time to 0 seconds. * wait for 100.5 seconds. * check if PHC time equal to 101.XX seconds. Usage: $ ./phc.sh /dev/ptp It is possible to run a subset of the tests, for example: * To run only the "settime" test: $ TESTS="settime" ./phc.sh /dev/ptp Signed-off-by: Shalom Toledo Reviewed-by: Petr Machata Acked-by: Richard Cochran Tested-by: Vladimir Oltean Signed-off-by: Ido Schimmel Signed-off-by: David S.
