| |
Currently the OS ignores EC panics when they occur. After reporting a panic, the EC will force a hard reset, possibly after a short delay. This may cause loss of data.
These patches add a handler for CrOS EC panics. When a panic is detected the OS will attempt to flush critical data for debugging purposes and attempt an orderly shutdown.
Changelog since v2: - Minor updates to commit messages
Changelog since v1: - Updated commit messages - Split into two patches - Moved panic handle before mkbp loop - Switched to dev_emerg
