Subject: [RFC PATCH v2] lightnvm: pblk
Date: Sat, 25 Feb 2017 17:53:00 +0100 [thread overview]
Message-ID: <1488041581-17379-1-git-send-email-javier@cnexlabs.com> (raw)
This patch introduces pblk, a new target for LightNVM implementing a
full host-based FTL. Details on the commit message.
Changes since v1:
* Rebase on top of Matias' for-4.12/core
* Move from per-LUN block allocation to a line model. This means that a
whole lines across all LUNs is allocated at a time. Data is still
stripped in a round-robin fashion at a page granurality.
* Implement new disk format scheme, where metadata is stored per line
instead of per LUN. This allows for space optimizations.
* Improvements on GC workqueue management and victim selection.
* Implement sysfs interface to query pblk's operation and statistics.
* Implement a user - GC I/O rate-limiter
* Various bug fixes
