Jim Cromie 6ea3bf466a dyndbg: test DECLARE_DYNDBG_CLASSMAP, sysfs nodes ... Demonstrate use of DECLARE_DYNDBG_CLASSMAP macro, and expose them as sysfs-nodes for testing. For each of the 4 class-map-types: - declare a class-map of that type, - declare the enum corresponding to those class-names - share _base across 0..30 range - add a __pr_debug_cls() call for each class-name - declare 2 sysnodes for each class-map for 'p' flag, and future 'T' flag These declarations create the following sysfs parameter interface: :#> pwd /sys/module/test_dynamic_debug/parameters :#> ls T_disjoint_bits T_disjoint_names T_level_names T_level_num do_prints p_disjoint_bits p_disjoint_names p_level_names p_level_num NOTES: The local wrapper macro is an api candidate, but there are already too many parameters. OTOH, maybe related enum should be in there too, since it has _base inter-dependencies. The T_* params control the (future) T flag on the same class'd pr_debug callsites as their p* counterparts. Using them will fail, until the dyndbg-trace patches are added in. :#> echo 1 > T_disjoint [ 28.792489] dyndbg: disjoint: 0x1 > test_dynamic_debug.T_D2 [ 28.793848] dyndbg: query 0: "class D2_CORE +T" mod:* [ 28.795086] dyndbg: split into words: "class" "D2_CORE" "+T" [ 28.796467] dyndbg: op='+' [ 28.797148] dyndbg: unknown flag 'T' [ 28.798021] dyndbg: flags parse failed [ 28.798947] dyndbg: processed 1 queries, with 0 matches, 1 errs [ 28.800378] dyndbg: bit_0: -22 matches on class: D2_CORE -> 0x1 [ 28.801959] dyndbg: test_dynamic_debug.T_D2: updated 0x0 -> 0x1 [ 28.803974] dyndbg: total matches: -22 Signed-off-by: Jim Cromie <jim.cromie@gmail.com> Link: https://lore.kernel.org/r/20220904214134.408619-22-jim.cromie@gmail.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2022-09-07 17:04:49 +02:00
