Currently if the userspace declares a int variable to store the out_fence
fd and pass it to OUT_FENCE_PTR the kernel will overwrite the 32 bits
above the int variable on 64 bits systems.
Fix this by making the internal storage of out_fence in the kernel a s32
pointer.

|
|
* This is the only hook to validate an atomic modeset update. This

|
* function must reject any modeset and state changes which the hardware
|
|
* or driver doesn't support. This includes but is of course not limited
|
|
* to:
|
|
*
|
|
* - Checking that the modes, framebuffers, scaling and placement
|
|
* requirements and so on are within the limits of the hardware.
|
|
*
|
|
* - Checking that any hidden shared resources are not oversubscribed.
|
|
* This can be shared PLLs, shared lanes, overall memory bandwidth,
|
|
* display fifo space (where shared between planes or maybe even
|
|
* CRTCs).
|
|
*
|
|
* - Checking that virtualized resources exported to userspace are not
|
|
* oversubscribed. For various reasons it can make sense to expose
|
|
* more planes, crtcs or encoders than which are physically there. One
|
|
* example is dual-pipe operations (which generally should be hidden
|
|
* from userspace if when lockstepped in hardware, exposed otherwise),
|
|
* where a plane might need 1 hardware plane (if it's just on one
|
|
* pipe), 2 hardware planes (when it spans both pipes) or maybe even
|
|
* shared a hardware plane with a 2nd plane (if there's a compatible
|
|
* plane requested on the area handled by the other pipe).
|
|
*
|
|
* - Check that any transitional state is possible and that if
|
|
* requested, the update can indeed be done in the vblank period
|
|
* without temporarily disabling some functions.
|
|
*
|
|
* - Check any other constraints the driver or hardware might have.
|
|
*
|
|
* - This callback also needs to correctly fill out the &drm_crtc_state
|
|
* in this update to make sure that drm_atomic_crtc_needs_modeset()
|
|
* reflects the nature of the possible update and returns true if and
|
|
* only if the update cannot be applied without tearing within one
|
|
* vblank on that CRTC. The core uses that information to reject
|
|
* updates which require a full modeset (i.e. blanking the screen, or
|
|
* at least pausing updates for a substantial amount of time) if
|
|
* userspace has disallowed that in its request.
|
|
*
|
|
* - The driver also does not need to repeat basic input validation
|
|
* like done for the corresponding legacy entry points. The core does
|
|
* that before calling this hook.
|
|
*

|
* See the documentation of @atomic_commit for an exhaustive list of

|

* - -ENOMEM, if allocating additional state sub-structures failed due
|
|
* to lack of memory.
|
|
*
|
|
* - -EINTR, -EAGAIN or -ERESTARTSYS, if the IOCTL should be restarted.

|
* This can either be due to a pending signal, or because the driver

|
|

*
|
|
* NOTE:
|
|
*
|
|
* Drivers are not allowed to shut down any display pipe successfully
|
|
* enabled through an atomic commit on their own. Doing so can result in
|
|
* compositors crashing if a page flip is suddenly rejected because the

* pipe is off.

|
|
* RETURNS:

|
* an earlier updated pending. Drivers are allowed to support a queue
|
|
* of outstanding updates, but currently no driver supports that.
|
|
* Note that drivers must wait for preceding updates to complete if a
|
|
* synchronous update is requested, they are not allowed to fail the
|
|
* commit in that case.
|
|
*
|
|
* - -ENOMEM, if the driver failed to allocate memory. Specifically
|
|
* this can happen when trying to pin framebuffers, which must only
|
|
* be done when committing the state.
|
|
*
|
|
* - -ENOSPC, as a refinement of the more generic -ENOMEM to indicate
|
|
* that the driver has run out of vram, iommu space or similar GPU

|
* address space needed for framebuffer.
|
|

* - -EIO, if the hardware completely died.
