2015-06-21nouveau: add asserts to make sure krefs are thereIlia Mirkin
This should help catch odd bugs at the callsites rather than much later on with completely bogus bo indices. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu>
2015-05-21nouveau: add coherent BO attributeAlexandre Courbot
Add a flag allowing Nouveau to specify that an object should be coherent at allocation time. This is required for some class of objects like fences which are randomly-accessed by both the CPU and GPU. This flag instructs the kernel driver to make sure the object remains coherent even on architectures for which coherency is not guaranteed by the bus.

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.

2015-03-13nouveau: 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>

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.

2013-01-07nouveau: disallow pushbuf BOs in multiple memory typesBen Skeggs
Under certain circumstances it's possible for libdrm to decide to move a GART|VRAM pushbuf to be VRAM-only. This causes the kernel to reject the command submission on GF8 and up, due to a stricter policy where buffers are only allowed to move to memory types that were specified at creation time. The simplest fix for this is to force the creation-time memory type for the lifetime of the push buffer. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
