Subject: [PATCH v2 0/4] fdp fixes, random placment id and xnvme support
Date: Wed, 12 Jul 2023 15:50:37 +0530 [thread overview]
Message-ID: <20230712102041.20283-1-ankit.kumar@samsung.com> (raw)
In-Reply-To: CGME20230712050110epcas5p1282a4e40485cb37545ec7cb55a3dcff1@epcas5p1.samsung.com
This series now enables us to either roundrobin or select a random
placement ID from the available ones. In future a non-unifrom
placement id selection such as zipf, pareto etc can be added.
The current boundary check for input placment ids was not correct.
Added a fix for that.
This series also adds FDP support to the xnvme I/O engine.
Changes since v1:
- Split the macro change and placement id check fix into separate
patches as suggested by Vincent
Ankit Kumar (4):
fdp: use macros
fdp: fix placement id check
fdp: support random placement id selection
engines/xnvme: add support for fdp
