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.
