ZMS is the abreviation of Zephyr Memory Storage. It is a storage developed to target especially the non erasable devices. The new memory storage system inherit from the NVS storage multiple features and introduce new ones : * Inherited features : - light key-value based storage - cache for entries - Wear Leveling of flash memory - Resilience to power failures * New features : - cycle counter for non erasable devices (instead of erase emulation) - Keys up to 32-bit - Built-in support of CRC32 for data - Small size data (<= 8 bytes) integrated within entries Signed-off-by: Riadh Ghaddab <[email protected]> (cherry picked from commit d4e246d)
List of added tests : - zms.test_delete - zms.test_zms_cache_collission - zms.test_zms_cache_gc - zms.test_zms_cache_hash_quality - zms.test_zms_cache_init - zms.test_zms_corrupted_sector_close_operation - zms.test_zms_corrupted_write - zms.test_zms_full_sector - zms.test_zms_gc - zms.test_zms_gc_3sectors - zms.test_zms_gc_corrupt_ate - zms.test_zms_gc_corrupt_close_ate - zms.test_zms_mount - zms.test_zms_write Signed-off-by: Riadh Ghaddab <[email protected]> (cherry picked from commit 004d6d6)
This adds a user application that shows the usage of ZMS The sample app shows three main functions of ZMS: - read/write/delete key/value pairs - fill all storage and delete it - calculate free remaining space Signed-off-by: Riadh Ghaddab <[email protected]> (cherry picked from commit fb7dae7)
This adds the documentation for the Zephyr Memory Storage system. Signed-off-by: Riadh Ghaddab <[email protected]> (cherry picked from commit 3c4fcaa)
This resolves some addressed comments in this PR zephyrproject-rtos/zephyr#77930 It adds as well a section in the documentation about some recommendations to increase ZMS performance. Signed-off-by: Riadh Ghaddab <[email protected]> (cherry picked from commit 46e1635)
Add myself "rghaddab" as maintainer to the ZMS storage system as I am the author of this new storage solution Signed-off-by: Riadh Ghaddab <[email protected]> (cherry picked from commit 6cc28c7)

…eads when performing a write ZMS checks if the data exists in the storage to avoid double writing the same data and save some memory cycle life time. However this downgrades the write performance. Enable this feature only when CONFIG_ZMS_NO_DOUBLE_WRITE is enabled. Signed-off-by: Riadh Ghaddab <[email protected]> (cherry picked from commit e0f0256)
