Current register contents are available under debugfs at: [debugfs]/pm_debug/registers/current To add a save point, do following: From module init (or somewhere before the save call, called only once): pm_dbg_init_regset(n); // n=1..4, allocates memory for dump area #n From arbitrary code location: pm_dbg_regset_save(n); // n=1..4, saves registers to dump area #n After this, the register dump can be seen under [debugfs]/pm_debug/registers/n Signed-off-by: Tero Kristo Signed-off-by: Kevin Hilman --- Reading git-diff-tree failed
