Details
pstore is the Kernel Persistent Storage Filesystem.
It was designed to store Kernel debug messages, reboot and shutdown logs, dmesg tails and kernel panic logs.
pstore is implemented in the builtin modules pstore.ko and ramoops.ko. Both are part of Linux, see the source in fs/pstore.
The filesystem is mounted in head (initscr) into the Sys-Filesystem tree:
mount -t pstore pstore /sys/fs/pstore
pstore is used for some crash logs:
Reboot Info:
- procfs: info, reboot_status
- kernel: avm_reboot_status.ko, reboot_status.ko
Crash Logs: - user mode crashes
- bootenv: crash (bootenv)
- tffs: crash.log (tffs)
- procfs: crash.log (procfs), crash (procfs), crash2 (procfs)
- temp: crash.log (temp)
- pipes: crash.log (pipe)
Panic Logs: - kernel crashes
- tffs: panic (tffs)
- procfs: panic (procfs), panic2 (procfs), avm_panic_cr, avm_panic_sd
- temp: panic (temp)
- pstore: console-ramoops-0
User Logs: - user stuff
- procfs: user (procfs), user2
Module Logs: - kernel modules
- procfs: antfs_logger, capicodec

Dependencies
Daily updated index of all dependencies of this filesystem. Last update: GMT.
A * in the Mod column marks info from Supportdata-Probes, which will always stay incomplete.
A ** in the Mod column marks info from Supportdata2 probes, which by their nature will stay way more incomplete.
A - in the Mod column marks manual research, the Firmware then shows where the item occurs, not the Relation.

Model-Matrix
Daily updated index of the presence, path and size of this filesystem for each model. Last update: 2024-04-19 06:37 GMT.
Showing all models using this filesystem. Click any column header (click-wait-click) to sort the list by the respective data.
The (main/scrpn/boot/arm/prx/atom) label in the Model column shows which CPU is meant for models with multiple Linux instances.
Note that this list comes from Supportdata-Probes, which can have arbitrary settings and come from different firmware versions.
It doesn't say much if a model is not listed here. It may be a missing supportdata file or just a disabled feature.
