| * selftests: watchdog: accept multiple params on command lineTimur Tabi2017-05-021-27/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Watchdog drivers are not required to retain programming information, such as timeouts, after the watchdog device is closed. Therefore, the watchdog test should be able to perform multiple actions after opening the watchdog device. For example, to set the timeout to 10s and ping every 5s: watchdog-test -t 10 -p 5 -e Also, display the periodic decimal point only if the keep-alive call succeeds.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Man page of mmap() says that portable applications should ensure fd argument to be -1 if MAP_ANONYMOUS flag is set as below: ``` The mapping is not backed by any file; its contents are initialized to zero. The fd and offset arguments are ignored; however, some implementations require fd to be -1 if MAP_ANONYMOUS (or MAP_ANON) is specified, and portable applications should ensure this. ``` However, few mmap() calls under selftests/vm/ uses 0 as fd though they use MAP_ANONYMOUS flag. This commit changes the argument to be -1 as recommended.

| * kselftest: ftrace: Fix to compare a zero-filled hex valueMasami Hiramatsu2017-04-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix to compare a zero-filled hexadecimal value with a part of string of long hexadecimal value. In check_types(), the last part of testcase compares with the hex value formatted by "%x" with a part of a string of long hex value (trimmed by tail -c and head -c). However, if that part of long hex value contains zero (e.g. "05" of "a3082059"), printf generated value (e.g. "5") is diffrent string, and the test case failed. To fix this, pass "%02x" instead of "%x" to printf.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Provide an interactive command to reset the tracepoint statistics. Requires some extra work for debugfs, as the counters cannot be reset. On the up side, this offers us the opportunity to have debugfs values reset on startup and whenever a filter is modified, becoming consistent with the tracepoint provider. As a bonus, 'kvmstat -dt' will now provide useful output, instead of mixing values in totally different orders of magnitude. Furthermore, we avoid unnecessary resets when any of the filters is "changed" interactively to the previous value.

| * | tools/kvm_stat: add option '--guest'Stefan Raspl2017-03-292-2/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new option '-g'/'--guest' to select a particular process by providing the QEMU guest name. Notes: - The logic to figure out the pid corresponding to the guest name might look scary, but works pretty reliably in practice; in the unlikely event that it returns add'l flukes, it will bail out and hint at using '-p' instead, no harm done. - Mixing '-g' and '-p' is possible, and the final instance specified on the command line is the significant one. This is consistent with current behavior for '-p' which, if specified multiple times, also regards the final instance as the significant one.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Updating the fields of the TracepointProvider does not propagate changes to the tracepoints. This shows when a pid filter is enabled, whereby subsequent extensions of the fields of the Tracepoint provider (e.g. by toggling drilldown) will not modify the tracepoints as required. To reproduce, select a specific process via interactive command 'p', and enable drilldown via 'x' - none of the fields with the braces will appear although they should. The fix will always leave all available fields in the TracepointProvider enabled.
