2017-02-17drm/nouveau/fifo/gf100-: provide notification to user if channel is killedBen Skeggs
There are instances (such as non-recoverable GPU page faults) where NVKM decides that a channel's context is no longer viable, and will be removed from the runlist. This commit notifies the owner of the channel when this happens, so it has the opportunity to take some kind of recovery action instead of hanging. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2017-02-17drm/nouveau/drm/nouveau/led: prevent a possible use-after-freeMartin Peres
If the led class registration fails, we free drm->led but do not reset it to NULL, which means that the suspend/resume/fini function will act as if everything went well in init() and will likely crash the kernel. This patch adds the missing drm->led = NULL.

2017-02-17gpu: ipu-v3: Stop overwriting pdev->dev.of_node of child devicesPhilipp Zabel
Setting dev->of_node changes the modalias and breaks module autoloading. Since there is an of_node field in the platform data passed to child devices, we don't even need this anymore. Suggested-by: Russell King <linux@armlinux.org.uk> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
2017-02-17gpu: ipu-v3: export ipu_csi_set_downsizePhilipp Zabel
This function will be used by the media drivers and needs to be exported to allow them to be built as modules. Reported-by: Russell King <linux@armlinux.org.uk> Fixes: 867341b95891 ("gpu: ipu-v3: add ipu_csi_set_downsize") Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
2017-02-17drm/imx: lift 64x64 pixel minimum framebuffer size requirementPhilipp Zabel
There is no reason to limit framebuffer size to 64x64 pixels at a minimum on creation. The actual scanout limitations (width >= 13 for the base plane and height >= 2) are checked in atomic_check. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Reviewed-by: Lucas Stach <l.stach@pengutronix.de>
2017-02-17drm/imx: imx-tve: Do not set the regulator voltageFabio Estevam
Commit deb65870b5d9d ("drm/imx: imx-tve: check the value returned by regulator_set_voltage()") exposes the following probe issue: 63ff0000.tve supply dac not found, using dummy regulator imx-drm display-subsystem: failed to bind 63ff0000.tve (ops imx_tve_ops): -22 When the 'dac-supply' is not passed in the device tree a dummy regulator is used and setting its voltage is not allowed. To fix this issue, do not set the dac-supply voltage inside the driver and let its voltage be specified in the device tree. Print a warning if the the 'dac-supply' voltage has a value different from 2.75V.

2017-02-17drm/nouveau: create userspace clients as subclientsBen Skeggs
This will allow the DRM to share memory objects between clients later down the track. For the moment, the only immediate benefit is less logic required to handle suspend/resume. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2017-02-17drm/nouveau/core/mm: replace region list with next pointerBen Skeggs
We never have any need for a double-linked list here, and as there's generally a large number of these objects, replace it with a single- linked list in order to save some memory. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-02-17drm/nouveau/core/client: allow creation of subclientsBen Skeggs
We want a supervisor client of NVKM (such as the DRM) to be able to allow sharing of resources (such as memory objects) between clients. To allow this, the supervisor creates all its clients as children of itself, and will use an upcoming ioctl to permit sharing. Currently it's not possible for indirect clients to use subclients. Supporting this will require an additional field in the main ioctl. This isn't important currently, but will need to be fixed for virt. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2017-02-17drm/nouveau/core/object: pass more args in oclassBen Skeggs
The fields were already in struct nvkm_oclass for some reason (probably as an accidental left-over). Preparation for supporting subclients. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-02-17drm/nouveau/core/object: pass client directly to ioctl handlersBen Skeggs
nvkm_object::client refers to the client that created the object, which, is currently always the same as the ioctl caller. Upcoming patches introduce the concept of subclients, where a parent is able to access the object trees of its children, making the above no longer true.

2017-02-17drm/nouveau/core/object: support lookup of specific object typesBen Skeggs
It turns out we have a nice and convenient way of looking up a specific object type already, by using the func pointer as a key. This will be used to remove the separate object trees for each type we need to be able to search for. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
