It is a backend to pstore, so this node is named -"ramoops" after the backend, rather than "pstore" which is the subsystem. - -Parts of this storage may be set aside for other persistent log buffers, such -as kernel log messages, or for optional ECC error-correction data. The total -size of these optional buffers must fit in the reserved region. - -Any remaining space will be used for a circular buffer of oops and panic -records. These records have a configurable size, with a size of 0 indicating -that they should be disabled. - -At least one of "record-size", "console-size", "ftrace-size", or "pmsg-size" -must be set non-zero, but are otherwise optional as listed below. - - -Required properties: - -- compatible: must be "ramoops" - -- memory-region: phandle to a region of memory that is preserved between - reboots - - -Optional properties: - -- ecc-size: enables ECC support and specifies ECC buffer size in bytes - (defaults to 0: no ECC) - -- record-size: maximum size in bytes of each dump done on oops/panic - (defaults to 0: disabled) - -- console-size: size in bytes of log buffer reserved for kernel messages - (defaults to 0: disabled) - -- ftrace-size: size in bytes of log buffer reserved for function tracing and - profiling (defaults to 0: disabled) - -- pmsg-size: size in bytes of log buffer reserved for userspace messages - (defaults to 0: disabled) - -- unbuffered: if present, use unbuffered mappings to map the reserved region - (defaults to buffered mappings) - -- no-dump-oops: if present, only dump panics (defaults to panics and oops) |
