23/* Information about the kgdb test suite.
24 * -------------------------------------
25 *
26 * The kgdb test suite is designed as a KGDB I/O module which
27 * simulates the communications that a debugger would have with kgdb.
28 * The tests are broken up in to a line by line and referenced here as
29 * a "get" which is kgdb requesting input and "put" which is kgdb
30 * sending a response.
31 *
32 * The kgdb suite can be invoked from the kernel command line
33 * arguments system or executed dynamically at run time. The test
34 * suite uses the variable "kgdbts" to obtain the information about
35 * which tests to run and to configure the verbosity level. The
36 * following are the various characters you can use with the kgdbts=
37 * line:
38 *
39 * When using the "kgdbts=" you only choose one of the following core
40 * test types:
41 * A = Run all the core tests silently
42 * V1 = Run all the core tests with minimal output
43 * V2 = Run all the core tests in debug mode
44 *
45 * You can also specify optional tests:
46 * N## = Go to sleep with interrupts of for ## seconds
47 * to test the HW NMI watchdog
48 * F## = Break at do_fork for ## iterations
49 * S## = Break at sys_open for ## iterations
50 *
51 * NOTE: that the do_fork and sys_open tests are mutually exclusive.
52 *
53 * To invoke the kgdb test suite from boot you use a kernel start
54 * argument as follows:
55 * kgdbts=V1 kgdbwait
56 * Or if you wanted to perform the NMI test for 6 seconds and do_fork
57 * test for 100 forks, you could use:
58 * kgdbts=V1N6F100 kgdbwait
59 *
60 * The test suite can also be invoked at run time with:
61 * echo kgdbts=V1N6F100 > /sys/module/kgdbts/parameters/kgdbts
62 * Or as another example:
63 * echo kgdbts=V2 > /sys/module/kgdbts/parameters/kgdbts
64 *
65 * When developing a new kgdb arch specific implementation or
66 * using these tests for the purpose of regression testing,
67 * several invocations are required.
68 *
69 * 1) Boot with the test suite enabled by using the kernel arguments
70 * "kgdbts=V1F100 kgdbwait"
71 * ## If kgdb arch specific implementation has NMI use
72 * "kgdbts=V1N6F100
73 *
74 * 2) After the system boot run the basic test.
75 * echo kgdbts=V1 > /sys/module/kgdbts/parameters/kgdbts
76 *
77 * 3) Run the concurrency tests. It is best to use n+1
78 * while loops where n is the number of cpus you have
79 * in your system. The example below uses only two
80 * loops.
81 *
82 * ## This tests break points on sys_open
83 * while [ 1 ] ; do find / > /dev/null 2>&1 ; done &
84 * while [ 1 ] ; do find / > /dev/null 2>&1 ; done &
85 * echo kgdbts=V1S10000 > /sys/module/kgdbts/parameters/kgdbts
86 * fg # and hit control-c
87 * fg # and hit control-c
88 * ## This tests break points on do_fork
89 * while [ 1 ] ; do date > /dev/null ; done &
90 * while [ 1 ] ; do date > /dev/null ; done &
91 * echo kgdbts=V1F1000 > /sys/module/kgdbts/parameters/kgdbts
92 * fg # and hit control-c
