Subject: 2.6.39.3 nouveau_gart_manager_new() leaks memory
Date: Thu, 28 Jul 2011 12:07:53 +0200 [thread overview]
Message-ID: <20110728100753.GA16736@janus> (raw)
/proc/slabinfo shows an anomaly on a 2.6.39.3 x86_64 system. After
running F14 + kde4 for a while it shows high kmalloc-192 numbers:
# name <active_objs> <num_objs> <objsize> <objperslab> <pagesperslab>...
kmalloc-192 735694 735723 264 31 2 : tunables 0 0 0 : slabdata 23733 23733 0
Digging in /sys/kernel/slab/kmalloc-192/alloc_calls one line stands out:
701960 nouveau_gart_manager_new+0x5d/0xf0 age=24/7405655/87972315 pid=1-4920 cpus=0-3
There are 709907 allocations total and according to
/sys/kernel/slab/kmalloc-192/free_calls there are 52245 free
calls total.
