2017-02-17drm/nouveau/fifo/gk104-: preempt recoveryBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-02-17drm/nouveau/fifo/gk104-: trigger mmu fault before attempting engine recoveryBen Skeggs
Greatly improves the chances of recovering the GPU from a CTXSW_TIMEOUT. Tested with piglit's arb_shader_image_load_store-atomicity, which causes GR to hang in such a way that recovery failed (CTXSW_TIMEOUT continually re-triggers). Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2017-02-17drm/nouveau/fifo/gk104-: reset all engines a killed channel is still active onBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-02-17drm/nouveau/fifo/gk104-: refactor recovery codeBen Skeggs
This will serve as a basis for implementing some improvements to how we recover the GPU from channel errors. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-02-17drm/nouveau/fifo/gk104-: better detection of chid when parsing engine statusBen Skeggs
The previous commit simply changes the interface, but should result in the same behaviour as previously. This commit has been split out from it as it can result in a different channel being selected. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-02-17drm/nouveau/fifo/gk104-: separate out engine status parsingBen Skeggs
We'll be wanting to reuse this logic in more places. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-02-17drm/nouveau/fifo: add an api for initiating channel recoveryBen Skeggs
This will be used by callers outside of fifo interrupt handlers. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-02-17drm/nouveau/top: add function to translate subdev index to mmu fault idBen Skeggs

Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-02-17drm/nouveau/core: add engine method to assist in determining chsw directionBen Skeggs
FIFO gives us load/save/switch status, and we need to be able to determine which direction a "switch" is failing during channel recovery. In order to do this, we apparently need to query the engine itself. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-02-17drm/nouveau: check for dead channel before trying to idleBen Skeggs
This prevents *very* long waits while attempting to destroy channels after a fault has occurred. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-02-17drm/nouveau: request notifications for channels that have been killedBen Skeggs
These will be used to improve error recovery behaviour. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
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/fifo/g84-: rename non-stall interrupt eventBen Skeggs

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.

2017-02-17drm/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/i915/gvt: Fix check error on opregion.cZhenyu Wang
As we switched to memremap for opregion, shouldn't use any __iomem for that, and move to use memcpy instead.

Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
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

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>
