...uAPI. Hence, fix this up for the new uAPI and split up the va_len field of struct drm_nouveau_exec_push, such that we keep 32bit for va_len and 32bit for flags. For drm_nouveau_gem_pushbuf_push::length at least provide NOUVEAU_GEM_PUSHBUF_NO_PREFETCH to indicate the bit shift. While at it, fix up nv50_dma_push() as well, such that the caller doesn't need to encode the NO_PREFETCH flag into the length parameter.

Perhaps originally true(?), but nothing suggests, guards, or enforces the assumption, and it's not true in practice. 0x7fffff is not the maximum possible push buffer size submitted for IB-mode DMA transfers, nor is it the maximum...

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(),

From: Thierry Reding <treding at nvidia.com> Hi, This series implements a new IOCTL to submit push buffers that can optionally return a sync FD or sync object to userspace. This is useful in cases where userspace wants to synchronize operations between the GPU and another driver (such as KMS for display). Among other things this allows extensions such as eglDupNativeFenceFDANDROID to be
