2013-11-07nouveau: prevent undefined behavior in nouveau_pushbuf_reloc with gcc-4.8Maarten Lankhorst1-1/+2
Reported-by: ronald645@gmail.com Bisected-by (gcc): Andreas Radke <a.radke@arcor.de> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=71116 Signed-off-by: Maarten Lankhorst <maarten.lankhorst@canonical.com>
2013-03-26nouveau: add a way to override single pushbuffer memory limitsMarcin Slusarz3-4/+21
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 Skeggs1-4/+4
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 Slusarz2-5/+4
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>

2010-10-31nouveau: Avoid unnecessary call to CPU_FINI.Francisco Jerez2-1/+5

2010-02-16nouveau: interface changes for 0.0.16 DRMLuca Barbieri10-350/+344
This commit encompasses the changes necessary to run on top of the 0.0.16 nouveau interface, additional APIs to support the new features of the interface, as well as code from Luca Barbieri to improve the pushbuf interface, which just happens to break nouveau's libdrm ABI so was delayed until now. API changes as a result of 0.0.16 DRM interface: 1. No more bo_pin()/bo_unpin(), these were only there for UMS and we no longer support it. 2. Any random nouveau_bo can be submitted to the GPU as a push buffer. 3. Relocations can be applied on any nouveau_bo This patch changes the pushbuffer ABI to: 1. No longer use/expose nouveau_pushbuffer. Everything is directly in nouveau_channel. This saves the extra "pushbuf" pointer dereference. 2. Use cur/end pointers instead of tracking the remaining size. Pushing data now only needs to alter cur and not both cur and remaining. The goal is to make the *_RING macros faster and make the interface simpler and cleaner in the process. The *_RING APIs are unchanged, but those are inlined and the ABI is changed. Also, anything accessing pushbuf->remaining instead of using AVAIL_RING will need to be fixed.
