Subject: [RFC][PATCH 0/5] VM_PINNED
Date: Mon, 26 May 2014 16:56:05 +0200 [thread overview]
Message-ID: <20140526145605.016140154@infradead.org> (raw)
Hi all,
I mentioned at LSF/MM that I wanted to revive this, and at the time there were
no disagreements.
I finally got around to refreshing the patch(es) so here goes.
These patches introduce VM_PINNED infrastructure, vma tracking of persistent
'pinned' page ranges. Pinned is anything that has a fixed phys address (as
required for say IO DMA engines) and thus cannot use the weaker VM_LOCKED. One
popular way to pin pages is through get_user_pages() but that not nessecarily
the only way.
Roland, as said, I need some IB assistance, see patches 4 and 5, where I got
lost in the qib and ipath code.
Patches 1-3 compile tested.
