Subject: [PATCH 0/2] zcrx and SQ/CQ queries
Date: Thu, 13 Nov 2025 10:48:56 +0000 [thread overview]
Message-ID: <cover.1763030298.git.asml.silence@gmail.com> (raw)
Note: depends on the 6.19 zcrx updates, and based on top of a
recent 6.18 query patch.
Introduce zcrx and SQ/CQ layout queries. The former returns what
zcrx features are available. And both return the ring size
information to help with allocation size calculation for user
provided rings like IORING_SETUP_NO_MMAP and.
IORING_MEM_REGION_TYPE_USER
