2007-07-09 | nouveau: rewrite gpu object code | Ben Skeggs | |
Allows multiple references to a single object, needed to support PCI(E)GART scatter-gather DMA objects which would quickly fill PRAMIN if each channel had its own. Handle per-channel private instmem areas. This is needed to support NV50, but might be something we want to do on earlier chipsets at some point? Everything that touches PRAMIN is a GPU object. | |||

2007-06-28 | nouveau: Nuke DMA_OBJECT_INIT ioctl (bumps interface to 0.0.7) | Ben Skeggs | |
For various reasons, this ioctl was a bad idea. At channel creation we now automatically create DMA objects covering available VRAM and GART memory, where the client used to do this themselves. However, there is still a need to be able to create DMA objects pointing at specific areas of memory (ie. notifiers). Each channel is now allocated a small amount of memory from which a client can suballocate things (such as notifiers), and have a DMA object created which covers the suballocated area. The NOTIFIER_ALLOC ioctl exposes this functionality. |
