This patchset proposes to introduce a "staging" module option to dynamically enable features (mostly ioctls) that are merged but may be refined before they are declared "stable". The second patch illustrates the use of this staging option with the SET_TILING ioctl, which can be used to specify the tiling options of a PRIME-imported buffer. The staging parameter will allow us

Hello, Could someone briefly describe (or point me to the documentation) what can be a reason for getting NV_PFIFO_INTR_DMA_PUSHER status (nouveau_fifo_irq_handler). This started happening immediately after I set the nouveau_vram_pushbuf flag to TRUE ,it's 100% repetitive and causes fences not to be signaled. Below is the debug log from moment of creation of fifo 1 to some point in time where fences should already be signaled: [drm] nouveau _redefined_nouveau_channel_alloc: initialised FIFO 1 [drm] nouveau Ch0/0x000000d0: 0...

It has been a couple of months since v4 - apologies for this. v4 has not received many comments, but this version addresses them and makes a new attempt at pushing the critical bit for GK20A and Nouveau on ARM in general. As a reminder, this series addresses the memory coherency issue that we are seeing on ARM platforms. Contrary to x86 which invalidates the PCI caches whenever a write is made by

Hi there, Resending these now that they've had some more polish and testing, and I heard that Ben's vacation is over :-) These patches work as a starting point for more explicit error mechanisms and better robustness. At the moment, when a job hangs or faults, it seems that nouveau doesn't quite know how to handle the situation and often results in a hang. Some of these situations

I made a little changes in this series: 1. merge the two last patches together 2. unify the private data interface with the drm debugfs one now it should be very obvious for a new dev on how to add new files to debugfs and how to get access to the nouveau structs Karol Herbst (5): debugfs: add infrastructure to add files with other fops than only read debugfs: rename functions to

This is the first set of patches to make Nouveau work on Tegra. Those are only the obvious correctness fixes, a lot of optimization work remains to be done, but at least it's enough to get accel working and let the machine survive a piglit run. A new BO flag is introduced to allow userspace to hint the kernel about possible optimizations. Lucas Stach (6): drm/ttm: recognize ARM arch in
