2021-05-08nvc0: Remove unnecessary bsp_bo NULL check.Vinson Lee1-1/+1
Fix defect reported by Coverity Scan. Dereference before null check (REVERSE_INULL) check_after_deref: Null-checking bsp_bo suggests that it may be null, but it has already been dereferenced on all paths leading to the check.

2017-01-12nouveau: take extra push space into account for pushbuf_space callsIlia Mirkin1-6/+1
Ever since a long time ago when I messed around with fences, I ensure that after a PUSH_SPACE call there is enough space to write a fence out into the pushbuf. However the PUSH_SPACE macro is not all-knowing, and so sometimes we have to invoke nouveau_pushbuf_space manually with the relocs/pushes args set. If we don't take the extra allocation from PUSH_SPACE into account, then we will end up accidentally flushing when the code was not expecting a flush. This can lead to various runtime and rendering failures. The amount of extra allocation isn't that important - it has to be at least 8 based on the current nouveau_winsys.h setting, but even more won't hurt. I just rounded up to powers of 2.

We already deref it earlier. And these are all allocated on load. Spotted by Coverity. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu>

2016-01-05nouveau: split nouveau_vp3_bsp in begin/next/endJulien Isorce1-2/+3
It allows to call nouveau_vp3_bsp_next multiple times between one begin/end.

H264 doesn't have a bitplane bo. We just need a device reference, so use the one from the client. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Cc: "11.0 11.1" <mesa-stable@lists.freedesktop.org>

2014-09-11nouveau: re-allocate bo's on overflowMaarten Lankhorst1-2/+45
The BSP bo might be too small to contain all of the bsp data, bump its size on overflow. Also bump inter_bo when this happens, it might be too small otherwise. Signed-off-by: Maarten Lankhorst <maarten.lankhorst@canonical.com> Cc: "10.2 10.3" <mesa-stable@lists.freedesktop.org>
2013-09-11Move nv30, nv50 and nvc0 to nouveau.Johannes Obermayr1-0/+155
It is planned to ship openSUSE 13.1 with -shared libs. nouveau.la, nv30.la, nv50.la and nvc0.la are currently LIBADDs in all nouveau related targets. This change makes it possible to easily build one shared libnouveau.so which is then LIBADDed. Also dlopen will be faster for one library instead of three and build time on -jX will be reduced. Whitespace fixes were requested by 'git am'.
