Subject: [PATCH 00/10] per-process address spaces for MMUv2
Date: Wed, 19 Dec 2018 15:45:36 +0100	[thread overview]
Message-ID: <20181219144546.28224-1-l.stach@pengutronix.de> (raw)

Hi all,

the following patches finally implement one of the longstanding TODO
items in the etnaviv driver: per-process address spaces. They are only
enabled for MMUv2, as switching the MMU context on MMUv1 would require
a full stop of the FE, which I deemed too expensive to do on potentially
every submitted commandstream.

For now this only provides better isolation between GPU clients, but it
is also a big step in the direction of supporting softpin. Softpin will
later be used by GC7000 userspace drivers to deal with texture descriptors
without the need to add even more relocation interfaces to the etnaviv
UAPI.

The changes are big and pretty disruptive, so I acknowledge that they
aren't prime targets for a quick review, but I would appreciate a
second pairs of eyes on them.

FWIW, I've been running a variation of those patches for some time on
GC2000, GC3000 and GC7000.

Regards,
Lucas
