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.

This hides all the abi16_* functions and the nouveau_debug variable, they should have been private to begin with. Signed-off-by: Maarten Lankhorst <maarten.lankhorst@canonical.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>
2012-06-09nouveau: silence some remaining valgrind warningsMarcin Slusarz
Valgrind can't understand some of the fields passed to ioctls are overwritten by kernel, so we need to initialize them. Almost all of our ioctl wrappers already do it and the cost of remaining 3 is very small. Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com>

2012-04-14nouveau: pull in major libdrm rewriteBen Skeggs
Redesigned primarily to allow us to better take advantage of BO's having fixed GPU virtual addresses on GeForce 8 and up, and to reduce the overhead of handling relocations on earlier chipsets.
