This is a lot of prep-work for being able to send event notifications back to userspace. Events now contain data, rather than a "something just happened" signal. Handler data is now embedded into a containing structure, rather than being kmalloc()'d, and can optionally have the notify routine handled in a workqueue. Various races between suspend/unload with display HPD/DP IRQ handlers automagically solved as a result. Signed-off-by: NBen Skeggs <bskeggs@redhat.com>

Vblank irqs don't get disabled during suspend or driver unload, which causes irq delivery after "suspend" or driver unload, at least until the gpu is powered off. This could race with drm_vblank_cleanup() in the case of nouveau and cause a use-after-free bug if the driver is unloaded. More annoyingly during everyday use, at least on nv50 display engine (likely also others), vblank irqs are off after a resume from suspend, but the drm doesn't know this, so all vblank related functionality is dead after a resume. E.g., all windowed OpenGL clients will hang at swapbuffers time, as well as many fullscreen clients in many cases. This makes suspend/resume useless if one wants to use any OpenGL apps after the resume. In Linux 3.16, drm_vblank_on() was added, complementing the older drm_vblank_off() to solve these problems elegantly, so use those calls in nouveaus suspend/resume code. For kernels 3.8 - 3.15, we need to cherry-pick the drm_vblank_on() patch to support this patch.

Cards with nv04 display engine can't reliably use vblank counts and timestamps computed via drm_handle_vblank(), as the function gets invoked after sending the pageflip events. Fix this by defaulting to the old crtcid = -1 fallback path on <= NV-50 cards, and only using the precise path on NV-50 and later.

Now that CRTC's have a primary plane, there's no need to track the framebuffer in the CRTC. Replace all references to the CRTC fb with the primary plane's fb. This patch was generated by the Coccinelle semantic patching tool using the following rules: @@ struct drm_crtc C; @@ - (C).fb + C.primary->fb @@ struct drm_crtc *C; @@ - (C)->fb + C->primary->fb v3: Generate patch via coccinelle. Actual removal of crtc->fb has been moved to a subsequent patch. v2: Fixup several lingering crtc->fb instances that were missed in the first patch iteration.

*hpos horizontal scanout position doesn't need to be corrected to count the pixels between hactive end and htotal negative. That is only needed for *vpos to count lines until end of vblank for the vblank timestamping. Use hpos as is without correction. Removes occassional spikes in timestamps of up to 1 scanline duration, thereby improves accuracy to about +/- 2 usecs instead of +/- 12 usecs, wrt. true onset time as measured with high precision equipment on NV-A5.

Upcoming mobile Kepler GPUs (such as GK20A) use the platform bus instead of PCI to which Nouveau is tightly dependent. This patch allows Nouveau to handle platform devices by: - abstracting PCI-dependent functions that were typically used for resource querying and page mapping, - introducing a nv_device_is_pci() function that allows to make PCI-dependent code conditional, - providing a nouveau_drm_platform_probe() function that takes a GPU platform device to be probed. Core code as well as engine/subdev drivers are updated wherever possible to make use of these functions. Some older drivers are too dependent on PCI to be properly updated, but all newer code on which future chips may depend should at least be runnable with platform devices.

There is no reason to keep the gem object separately allocated. nouveau is the last user of gem_obj->driver_private, so if we embed it, we can get rid of 8bytes per gem-object. The implementation follows the radeon driver. bo->gem is only valid, iff the bo was created via the gem helpers _and_ iff the user holds a valid gem reference. That is, as the gem object holds a reference to the nouveau_bo. If you use nouveau_ref() to gain a bo reference, you are not guaranteed to also hold a gem reference. The gem object might get destroyed after the last user drops the gem-ref via drm_gem_object_unreference(). Use drm_gem_object_reference() to gain a gem-reference. For debugging, we can use bo->gem.filp != NULL to test whether a gem-bo is valid. However, this shouldn't be used for real functionality to avoid gem-internal dependencies. Note that the implementation follows the previous style. However, we no longer can check for bo->gem != NULL to test for a valid gem object. This wasn't done before, so we should be safe now.

All the gem based kms drivers really want the same function to destroy a dumb framebuffer backing storage object. So give it to them and roll it out in all drivers. This still leaves the option open for kms drivers which don't use GEM for backing storage, but it does decently simplify matters for gem drivers.

Use the new vma-manager infrastructure. This doesn't change any implementation details as the vma-offset-manager is nearly copied 1-to-1 from TTM. The vm_lock is moved into the offset manager so we can drop it from TTM. During lookup, we use the vma locking helpers to take a reference to the found object. In all other scenarios, locking stays the same as before. We always guarantee that drm_vma_offset_remove() is called only during destruction. Hence, helpers like drm_vma_node_offset_addr() are always safe as long as the node has a valid offset. This also drops the addr_space_offset member as it is a copy of vm_start in vma_node objects. Use the accessor functions instead. v4: - remove vm_lock - use drm_vma_offset_lock_lookup() to protect lookup (instead of vm_lock) Cc: Dave Airlie <airlied@redhat.com> Cc: Ben Skeggs <bskeggs@redhat.com> Cc: Maarten Lankhorst <maarten.lankhorst@canonical.com> Cc: Martin Peres <martin.peres@labri.fr> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: NDavid Herrmann <dh.herrmann@gmail.com> Reviewed-by: NDaniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: NDave Airlie <airlied@gmail.com>
