>From Android R onwards Google has restricted access to debugfs in user and user-debug builds. This restricts access to most of the features exposed through debugfs. 'Coredump' and 'Recovery' are critical interfaces that are required for remoteproc to work on Qualcomm Chipsets. This patch series adds recovery/coredump configuration to sysfs interface and disables coredump collection by default. Having coredump disabled by default on production devices makes sense. Changelog: v7 -> v6: - Keep the debugfs entries intact for now. - Reorder the patches to have a consistent sysfs interface. v6 -> v5: - Disable coredump collection by default - Rename the "default" configuration to "enabled" to avoid confusion v5 -> v4: - Fix the cover-letter of tha patch series. v4 -> v3: - Remove the feature flag to expose recovery/coredump v3 -> v2: - Remove the coredump/recovery entries from debugfs - Expose recovery/coredump from sysfs under a feature flag v1 -> v2: - Correct the contact name in the sysfs documentation. - Remove the redundant write documentation for coredump/recovery sysfs - Add a feature flag to make this interface switch configurable.
