From 40b6f2d020ca8074ed38a1b6bfa170aead1a170e Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sat, 25 Jul 2015 21:52:38 +0900 Subject: devres: add debug command to dump device resources This new command can dump all device resources associated to each device. The fields in every line shows: - The address of the resource - The size of the resource - The name of the release function - The stage in which the resource has been acquired (BIND/PROBE) Currently, there is no driver using devres, but if such drivers are implemented, the output of this command should look like this: => dm devres - root_driver - soc - extbus - serial@54006800 bfb541e8 (8 byte) devm_kmalloc_release BIND bfb54440 (4 byte) devm_kmalloc_release PROBE bfb54460 (4 byte) devm_kmalloc_release PROBE - serial@54006900 bfb54270 (8 byte) devm_kmalloc_release BIND - gpio@55000000 - i2c@58780000 bfb5bce8 (12 byte) devm_kmalloc_release PROBE bfb5bd10 (4 byte) devm_kmalloc_release PROBE - eeprom bfb54418 (12 byte) devm_kmalloc_release BIND Signed-off-by: Masahiro Yamada Acked-by: Simon Glass --- include/dm/util.h | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'include/dm') diff --git a/include/dm/util.h b/include/dm/util.h index 7dbed6793f..15daa3d19f 100644 --- a/include/dm/util.h +++ b/include/dm/util.h @@ -39,4 +39,13 @@ void dm_dump_all(void); /* Dump out a list of uclasses and their devices */ void dm_dump_uclass(void); +#ifdef CONFIG_DEBUG_DEVRES +/* Dump out a list of device resources */ +void dm_dump_devres(void); +#else +static inline void dm_dump_devres(void) +{ +} +#endif + #endif -- cgit v1.2.1
