2011-11-27nouveau: Mark nouveau subchannel unbound nouveau_grobj_freeMaarten Lankhorst
Valgrind throws warns about a user-after-free if you try to bind a new subchannel after the old one in that slot was freed, so remove it from the channel list. Signed-off-by: Maarten Lankhorst <m.b.lankhorst@gmail.com>
2011-10-19nouveau: free in error path if drmAvailable fails.Dave Airlie

2010-12-21nouveau: fix up reloc_emit() to accept NULL target bufferBen Skeggs
The nvc0 gallium drivers passes NULL here to indicate to the memory manager that a buffer is being used, but without creating an actual reloc. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

It makes sure that GPU object destruction is executed in order with respect to the previous FIFO commands. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Acked-by: Ben Skeggs <bskeggs@redhat.com>
2010-10-31nouveau: Avoid unnecessary call to CPU_FINI.Francisco Jerez
nouveau_bo_unmap called the CPU_FINI IOCTL even if it was a NOSYNC mapping. It caused no harmful effects (actually CPU_FINI is a no-op on recent enough kernels) besides the precious CPU cycles being wasted. Signed-off-by: Francisco Jerez <currojerez@riseup.net>

2010-04-09nouveau: stop shipping nouveau_class.hBen Skeggs
The motivation behind this is that by shipping it here, it's essentially an API which causes issues while bisecting across changes to the header files.

2010-02-16nouveau: interface changes for 0.0.16 DRMLuca Barbieri
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.
