Subject: [PATCH v5 RFC 0/3] Generic IOMMU pooled allocator
Date: Sun, 22 Mar 2015 15:22:51 -0400 [thread overview]
Message-ID: <cover.1426986386.git.sowmini.varadhan@oracle.com> (raw)
Follows up on the feedback in the thread at
http://www.spinics.net/lists/sparclinux/msg13493.html
- removed ->cookie_to_index and ->demap indirection from the iommu_tbl_ops
The caller needs to call these functions as needed, before invoking
the generic arena allocator functions.
- added the "skip_span_boundary" argument to iommu_tbl_pool_init() for
those callers like LDC which do no care about span boundary checks.
Sowmini (2):
Break up monolithic iommu table/lock into finer graularity pools and
lock
Make sparc64 use scalable lib/iommu-common.c functions
Sowmini Varadhan (1):
Make LDC use common iommu poll management functions
