2015-05-06nouveau: restore check that avoids multiple user bos per kernel boBen Skeggs
Lost in 5ea6f1c32628887c9df0c53bc8c199eb12633fec, triggering fdo#89842. Unlike the PRIME fd->handle interfaces, the GEM_OPEN interface doesn't do anything at the kernel level to prevent this situation occuring, and we end up with multiple GEM handles for a single kernel buffer.

2015-04-28Add missing <strings.h> includesGreg Hackmann
A couple of files use ffs() without explicitly including strings.h. Some systems will pull in ffs()'s declaration through another header anyway, but not when compiling against bionic in AOSP master.

2015-04-28drm: remove drm_public macroEmil Velikov
Some compilers (like the Oracle Studio), require that the function declaration must be annotated with the same visibility attribute as the definition. As annotating functions with drm_public is no longer required just remove the macro.

2015-04-28nouveau: annotate the private symbolsEmil Velikov
They are less and easier to track than the public ones. The macro drm_public will be going away by the end of the series. Cc: Maarten Lankhorst <maarten.lankhorst@canonical.com> Cc: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Emil Velikov <emil.l.velikov@gmail.com>
2015-03-13nouveau: Do not add most bo's to the global bo list.Maarten Lankhorst
Only add wrapped bo's and bo's that have been exported through flink or dma-buf. This avoids a lock in the common case, and decreases traversal needed for importing a dma-buf or flink. Signed-off-by: Maarten Lankhorst <maarten.lankhorst@ubuntu.com> Tested-By: Emil Velikov <emil.l.velikov@gmail.com>
2015-03-13nouveau: make nouveau importing global buffers completely thread-safe, with ↵Maarten Lankhorst
tests While I've closed off most races in a previous patch, a small race still existed where importing then unreffing cound cause an invalid bo. Add a test for this case. Racing sequence fixed: - thread 1 releases bo, refcount drops to zero, blocks on acquiring nvdev->lock. - thread 2 increases refcount to 1. - thread 2 decreases refcount to zero, blocks on acquiring nvdev->lock. At this point the 2 threads will clean up the same bo. Signed-off-by: Maarten Lankhorst <maarten.lankhorst@ubuntu.com> Reviewed-By: Emil Velikov <emil.l.velikov@gmail.com>

2014-04-15nouveau: safen up nouveau_device list usage against concurrent accessMaarten Lankhorst
I cannot make nouveau_bo_wrap thread-safe (by design), but it seems to be used to convert drm fb's to nouveau_bo's and to get a notify handle from fifo->notify in nv30_screen.c Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Signed-off-by: Maarten Lankhorst <maarten.lankhorst@ubuntu.com>
2013-03-26nouveau: add a way to override single pushbuffer memory limitsMarcin Slusarz
Currently single pushbuffer can take up to 80% of VRAM and 80% of GART. As this value seems to be arbitrary (and user may need to set it differently) this patch adds support for 2 environment variables: NOUVEAU_LIBDRM_VRAM_LIMIT_PERCENT (default 80) NOUVEAU_LIBDRM_GART_LIMIT_PERCENT (default 80) which will let users override pushbuffer VRAM/GART limits.
