The overall goal of this patch series is to add the ability to read from IO mapped memory at the kdb prompt. This is something I've long wished to have but never got around to implementing until now.
As I tried to implement this, I realized that the existing "md" code was a bit of a mess. I spent a bunch of time cleaning up the function which made the ability to support iomapped memory atop that pretty simple. The cleanup code here is not quite a no-op. The "md" handling code has some esoteric corner cases that it handled and, as part of this, I removed some of the weird corners. I have a hard time believing anyone was relying on these, but if you think someone is then please yell. Also note that it would probably be good to add iomapped memory writes, but this series is already pretty long so maybe that can be done later. Douglas Anderson (13): kdb: Get rid of "minlen" for the "md" command kdb: Document the various "md" commands better kdb: Use "bool" in "md" implementation where appropriate kdb: Drop "offset" and "name" args to kdbgetaddrarg() kdb: Separate out "mdr" handling kdb: Remove "mdW" and "mdWcN" handling of "W" == 0 kdb: Tweak "repeat" handling code for "mdW" and "mdWcN" kdb: In kdb_md() make `repeat` and `mdcount` calculations more obvious kdb: Use 'unsigned int' in kdb_md() where appropriate kdb: Replease simple_strtoul() with kstrtouint() in kdb_md() kdb: Abstract out parsing for mdWcN kdb: Add mdpW / mdpWcN commands kdb: Add mdi, mdiW / mdiWcN commands to show iomapped memory kernel/debug/kdb/kdb_bp.c | 5 +- kernel/debug/kdb/kdb_bt.c | 4 +- kernel/debug/kdb/kdb_main.c | 309 +++++++++++++++++++-------------- kernel/debug/kdb/kdb_private.h | 5 +- kernel/debug/kdb/kdb_support.c | 48 +++++ 5 files changed, 236 insertions(+), 135 deletions(-) -- 2.45.2.627.g7a2c4fd464-goog _______________________________________________ Kgdb-bugreport mailing list Kgdb-bugreport@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/kgdb-bugreport
