Currently, NO_PREFETCH is passed implicitly through drm_nouveau_gem_pushbuf_push::length and drm_nouveau_exec_push::va_len. Since this is a direct representation of how the HW is programmed it isn't really future proof for a 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

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.

Introduce accessors for TTM buffer object memory that has been mapped into the kernel virtual address space or as IO memory. IO memory needs to be accessed via special accessor functions, not by dereferencing the iomem cookie. The wrappers hide the details of 32-bit access and honour the TTM map type. nv04_crtc_cursor_set() is changed to use the new wrappers. 'cursor' is received from

The following patchset remove use of the deprecated drmP.h header file in the nouveau driver(s). As preparation a dependency on drm_os_linux.h is dropped. The list of include files are sorted and are in some cases divided up in blocks of linux/* drm/* etc. The removal is divided up in a few patches that was the logical steps to remove the use of drmP.h. Build tested with allmodconfig and

Commit "drm/nouveau: port all engines to new engine module format" changed IB size calculation to be less wasteful, but didn't take into account already existing off-by-one bugs :). So: - ib_max is the last entry, so we need to +1 when calculating number of free entries - nv50_dma_wait already does +1 (for FIRE_RING), so we don't need another +1 on nouveau_gem_ioctl_pushbuf

Before this patch they were being reset to zero on every context switch instead of leaving the saved value, causing some context switching weirdness (the most serious symptom was the memory manager corrupting the BOs it migrated because of a malfunctioning M2MF).

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

Hello, I have my work on the nv vpe video decoder in a functional state. In case you didn't know this decoder accelerates mpeg2 video at the idct/mc level. I have verified that it works on nv40 hardware. I believe it works on nv30 hardware (and maybe some earlier hardware), but I cannot verify since I have none. I will reply with patches against the kernel, drm, ddx and mesa for
