Interrupt setting
Hi all,
I am a Nouveau user on FC12 with GeForce 9500GT.
I have read the Nouveau wiki documents, and they imply that there are ways
to set GPU to send interrupts to CPU, when we want to be notified for
something, e.g., when DMA transfer or GPU operation is completed.
By default, when I run an OpenGL demo application from Gallium3D, the driver
gets no interrupts from GPU in nouveau_irq_handler(),

[PATCH 1/3] drm/nouveau: Allocate a per-channel instance of NV_SW.
It will be useful for various synchronization purposes, mostly stolen
from "[PATCH] drm/nv50: synchronize user channel after buffer object
move on kernel channel" by Maarten Maathuis.

[PATCH 1/3] drm/nouveau: change channel regs mapping to ioremap
Use ioremap() for mapping the channel user regs (that are never exposed
to user space) instead of drm_addmap().
This removes the last use cases of drm_addmap/drm_rmmap from Nouveau.

[PATCH 1/3] Introduce nouveau_bo_wait for waiting on a BO with a GPU channel (v2)
Changes in v2:
- Addressed review comments
nouveau_bo_wait will make the GPU channel wait for fence if possible,
otherwise falling back to waiting with the CPU using ttm_bo_wait.
The nouveau_fence_sync function currently returns -ENOSYS, and is
the focus of the next patch.
