Usage: ipi_test.sh [OPTIONS]
Runs the basic test for inter-processor interrupts (IPI)
TEST: Call smp_call_function on each online CPU to test if all other CPUs
could receive the interrupts.
OPTIONS:
The kernel test support about the following parameters
-t | --times <interation count> Sets how many times to test IPI between every
two CPUs. For example, the following command will test IPI 10000
times. It will call smp_call_function on each online CPU to test
if all other CPUs could receive the interrupts.
e.g.
#./ipi_test.sh -t 10000
If no option, the default value would be 10000.
-r | --repeatability Sets 1000000 times as a large interation number to test
IPI.
TEST BEHAVIOR:
* Online CPUs and ensure all the CPUs are not removed. Test will call
* smp_call_function on each online CPU to test if all other CPUs could
* receive the interrupts.
target support: all
Notes:
If the script returns 0 and prints "Test passed", then the test was successful.
If the script returns nonzero and prints "Test failed", then the test failed.
