I'm planning to add functionality to the kernel which periodically dumps the EC console log and concatenates it so we can use it in bug reports and feedback. However, stitching together logs collected using the existing SNAPSHOT/READ commands is difficult. This adds a new version of READ which acts mostly the same but will only give you the difference between the two most recent snapshots when you pass the corresponding argument. BRANCH=ToT BUG=chromium:492721 TEST=On samus with kernel interface, cat /sys/kernel/debug/cros_ec/console_log and verify that the most recent bit of the log is printed, use spammy commands like 'accelinfo on' and make sure nothing breaks, check that 'ectool console' behavior has not changed Change-Id: Ib8216caa917715820c3e265400f0db2125e8808b Signed-off-by: Eric Caruso <ejcaruso@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/273581 Reviewed-by: Randall Spangler <rspangler@chromium.org> Reviewed-by: Gwendal Grignou <gwendal@chromium.org>
