>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. Coredump configuration needs to be set to "inline" in debug/test builds and "disabled" in production builds. Whereas recovery needs to be "disabled" for debugging purposes and "enabled" on production builds. This patch series removes the recovery/coredump entries from debugfs and moves them to sysfs. Also, this disables the coredump collection by default as this is a requirement for production devices. Changelog: 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.
