When doing a nop modeset we currently leave crtc->new_config point at the already freed temporary pipe_config. That will anger the sanity checks in intel_modeset_update_state() when the nop modeset gets followed by a GPU reset on gen3/4 where the display block gets fully reinitialized during the reset. So leave crtc->new_config alone until we know a modeset is actually required. Cc: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by:

The DRM connector's encoder pointer is managed internally by the DRM core and set to NULL when the DRM connector is disconnected from the CRTC it was attached to. This results in a NULL pointer dereference in the HDMI connector functions when trying to call the associated slave encoder's operations. Fix this by retrieving the slave encoder pointer from the R-Car connector structure instead of the DRM connector structure. Signed-off-by:

LRC object does not need to be mapped into the GGTT when dumping. A side-effect of this patch is that a compiler warning goes away (not checking return value of i915_gem_obj_ggtt_pin). v2: Broke out individual context dumping into a new function as the indentation was getting a bit crazy. Added notification of contexts with no gem object for debugging purposes. Removed unnecessary pin_pages and unpin_pages, replaced with explicit get_pages for the context object as there may be no backing store allocated at this time (Comment for get_pages says "Ensure that the associated pages are gathered from the backing storage and pinned into our object"). Improved error checking - get_pages and get_page are checked for failure. Signed-off-by:

Preparation for transition to planes, which use framebuffers for the cursor image. We've always done copies from the userspace buffer up until now for legacy reasons, there's no good reason to do so on the chipsets this code covers. Signed-off-by: -

We have the ability to move buffers around in the kernel if necessary, and should probably use it rather than failing if userspace passes us a non-contig buffer for a plane. The NOUVEAU_GEM_TILE_NONCONTIG flag from userspace will become a mere initial placement hint once all the relevant paths have been updated. Signed-off-by: -

A machine has been spotted where the ramcfg strap is "8", and the ramcfg xlat table goes 0-7,0-7, resulting in us selecting config 0 for memory items. On this particular system, config "8" is available and supposed to be used. It appears that starting from GT21x (where Mv2 appears), we're supposed to use the value in this table instead. One concern here is that not all the places we currently use ramcfg xlat are supposed to be treated the same now. The strap xlat table wasn't removed from the vbios either, presumably for some kind of good reason. Signed-off-by: -

We only support one kind of matching here (ramcfg strap), but it appears alternate methods are possible. I wrote a tool to scan our vbios repo for other types, but did not see any used. Hopefully this means there aren't any in the wild that will now break. Signed-off-by: -

On architectures for which access to GPU memory is non-coherent, caches need to be flushed and invalidated explicitly when BO control changes between CPU and GPU. This patch adds buffer synchronization functions which invokes the correct API (PCI or DMA) to ensure synchronization is effective. Based on the TTM DMA cache helper patches by Lucas Stach.

Specify TTM_PL_FLAG_UNCACHED when allocating GPFIFOs and fences to allow them to be safely accessed by the kernel without being synced on non-coherent architectures. Signed-off-by:

Alexandre Courbot authored
Allow nouveau_bo_new() to recognize the TTM_PL_FLAG_UNCACHED flag, which means that we want the allocated BO to be perfectly coherent between the CPU and GPU. This is useful on non-coherent architectures for which we do not want to manually sync some rarely-accessed buffers: typically, fences and pushbuffers. A TTM BO allocated with the TTM_PL_FLAG_UNCACHED on a non-coherent architecture will be populated using the DMA API, and accesses to it performed using the coherent mapping performed by dma_alloc_coherent().

Add a function allowing us to know whether a device is CPU-coherent, i.e. accesses performed by the CPU on GPU-mapped buffers will be immediately visible on the GPU side and vice-versa. For now, a device is considered to be coherent if it uses the PCI bus on a non-ARM architecture. Signed-off-by:
