When we find failures / regressions or when tests change from pass to fail we will report those on the mailing list. output: ------- [ 3.290336] ### dt-test ### start of unittest - you will see error messages [ 3.298352] ### dt-test ### EXPECT \ : Duplicate name in testcase-data, renamed to \"duplicate-name#1\" [ 3.298535] Duplicate name in testcase-data, renamed to \"duplicate-name#1\" [ 3.318485] ### dt-test ### EXPECT / : Duplicate name in testcase-data, renamed to \"duplicate-name#1\" [ 3.319418] ### dt-test ### pass of_unittest_check_tree_linkage():278 [ 3.335123] ### dt-test ### pass of_unittest_check_tree_linkage():279 [ 3.341662] ### dt-test ### pass of_unittest_check_phandles():387 Test job: https://lkft.validation.linaro.org/scheduler/job/4473059#L1019 > --- > Documentation/admin-guide/kernel-parameters.txt | 4 ++++ > drivers/of/unittest.c | 17 ++++++++++++++++- > 2 files changed, 20 insertions(+), 1 deletion(-) > > diff --git a/Documentation/admin-guide/kernel-parameters.txt b/Documentation/admin-guide/kernel-parameters.txt > index f5a27f067db9..045455f9b7e1 100644 > --- a/Documentation/admin-guide/kernel-parameters.txt > +++ b/Documentation/admin-guide/kernel-parameters.txt > @@ -5997,6 +5997,10 @@ > Note that genuine overcurrent events won't be > reported either. > > + unittest.hide_pass > + Disable printing individual drivers/of/unittest test > + pass messages. > + > unknown_nmi_panic > [X86] Cause panic on unknown NMI. > > diff --git a/drivers/of/unittest.c b/drivers/of/unittest.c > index 70992103c07d..2cfbdc6b29ac 100644 > --- a/drivers/of/unittest.c > +++ b/drivers/of/unittest.c > @@ -12,6 +12,7 @@ > #include <linux/errno.h> > #include <linux/hashtable.h> > #include <linux/libfdt.h> > +#include <linux/module.h> > #include <linux/of.h> > #include <linux/of_address.h> > #include <linux/of_fdt.h> > @@ -32,6 +33,19 @@ > > #include "of_private.h" > > +MODULE_LICENSE("GPL v2"); > +static bool hide_pass; > + > +static int __init hide_pass_setup(char *str) > +{ > + hide_pass = true; > + return 0; > +} > + > +early_param("hide_pass", hide_pass_setup); > +module_param(hide_pass, bool, 0); > +MODULE_PARM_DESC(hide_pass, "Disable printing individual of unittest pass messages"); > + > static struct unittest_results { > int passed; > int failed; > @@ -44,7 +58,8 @@ static struct unittest_results { > pr_err("FAIL %s():%i " fmt, __func__, __LINE__, ##__VA_ARGS__); \ > } else { \ > unittest_results.passed++; \ > - pr_debug("pass %s():%i\n", __func__, __LINE__); \ > + if (!hide_pass) \ > + pr_err("pass %s():%i\n", __func__, __LINE__); \ > } \ > failed; \ > }) > -- > Frank Rowand <frank.rowand@xxxxxxxx> -- Linaro LKFT https://lkft.linaro.org
