Description Alexander Larsson 2003-02-25 19:17:38 UTC
Every time I start and exit X the sum of "Active + Inact_dirty + Inact_laundry +
Inact_clean + MemFree" in /proc/meminfo drops by about 12 megs.

Commenting out Load "DRI" in XF86Config removes the leak.

Comment 4 Mike A. Harris 2003-02-25 19:28:57 UTC
attach /var/log/messages too to peekaboo at agpgart loading et al.

This also happens on at least i8x0 cards.
This is not nptl related, but seems rmap related.
Arjans kernel-2.4.20-5nonptlfixrmap build fixes it. Waiting on an NPTL enabled
build to test that.

Comment 7 Bill Nottingham 2003-02-27 17:15:50 UTC
Should be fixed in -6.

Comment 8 Jay Turner 2003-02-28 02:49:20 UTC
Fix confirmed with the latest kernel.

Comment 9 Mike A. Harris 2003-02-28 07:50:38 UTC
Just to clarify with a bit more detail for those who might find this bug
report when doing a bugzilla query, this problem was due to a refcount
bug in rmap with respect to PageReserved pages. DRM marks it's pages as
PageReserved and was affected by this bug. (In Arjan's words)

Problem fixed in kernel-2.4.20-6 by Arjan The Machine(TM)  ;o)
