2017-10-28drm/msm: Add per-instance submit queuesJordan Crouse
Currently the behavior of a command stream is provided by the user application during submission and the application is expected to internally maintain the settings for each 'context' or 'rendering queue' and specify the correct ones. This works okay for simple cases but as applications become more complex we will want to set context specific flags and do various permission checks to allow certain contexts to enable additional privileges. Add kernel-side submit queues to be analogous to 'contexts' or 'rendering queues' on the application side. Each file descriptor instance will maintain its own list of queues. Queues cannot be shared between file descriptors. For backwards compatibility context id '0' is defined as a default context specifying no priority and no special flags. This is intended to be the usual configuration for 99% of applications so that a garden variety application can function correctly without creating a queue. Only those applications requiring the specific benefit of different queues need create one. Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

2017-10-28drm/msm/adreno: load gpu at probe/bind timeRob Clark
Previously, in an effort to defer initializing the gpu until firmware was available (ie. rootfs mounted), the gpu was not loaded at when the subdevice was bound. Which resulted that clks/etc were requested in a place that devm couldn't really help unwind if something failed. Instead move request_firmware() to gpu->hw_init() and construct the gpu earlier in adreno_bind(). To avoid the rest of the driver needing to be aware of a gpu that hasn't managed to load firmware and hw_init() yet, stash the gpu ptr in the adreno device's drvdata, and don't set priv->gpu() until hw_init() succeeds.

2017-10-25drm: Add four ioctls for managing drm mode object leases [v7]Keith Packard
drm_mode_create_lease Creates a lease for a list of drm mode objects, returning an fd for the new drm_master and a 64-bit identifier for the lessee drm_mode_list_lesees List the identifiers of the lessees for a master file drm_mode_get_lease List the leased objects for a master file drm_mode_revoke_lease Erase the set of objects managed by a lease. This should suffice to at least create and query leases. Changes for v2 as suggested by Daniel Vetter <daniel.vetter@ffwll.ch>: * query ioctls only query the master associated with the provided file. * 'mask_lease' value has been removed * change ioctl has been removed. Changes for v3 suggested in part by Dave Airlie <airlied@gmail.com> * Add revoke ioctl. Changes for v4 suggested by Dave Airlie <airlied@gmail.com> * Expand on the comment about the magic use of &drm_lease_idr_object * Pad lease ioctl structures to align on 64-bit boundaries Changes for v5 suggested by Dave Airlie <airlied@gmail.com> * Check for non-negative object_id in create_lease to avoid debug output from the kernel. Changes for v6 provided by Dave Airlie <airlied@gmail.com> * For non-universal planes add primary/cursor planes to lease If we aren't exposing universal planes to this userspace client, and it requests a lease on a crtc, we should implicitly export the primary and cursor planes for the crtc. If the lessee doesn't request universal planes, it will just see the crtc, but if it does request them it will then see the plane objects as well. This also moves the object look ups earlier as a side effect, so we'd exit the ioctl quicker for non-existant objects. * Restrict leases to crtc/connector/planes. This only allows leasing for objects we wish to allow. Changes for v7 provided by Dave Airlie <airlied@gmail.com> * Check pad args are 0 * Check create flags and object count are valid. * Check return from fd allocation * Refactor lease idr setup and add some simple validation * Use idr_mutex uniformly (Keith) Signed-off-by: Keith Packard <keithp@keithp.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

Attempts to modify un-leased objects are rejected with an error. Information returned about unleased objects is modified to make them appear unusable and/or disconnected. Changes for v2 as suggested by Daniel Vetter <daniel.vetter@ffwll.ch>: * With the change in the __drm_mode_object_find API to pass the file_priv along, we can now centralize most of the lease-based access checks in that function. * A few places skip that API and require in-line checks.

2017-10-25drm: Add drm_object lease infrastructure [v5]Keith Packard
This provides new data structures to hold "lease" information about drm mode setting objects, and provides for creating new drm_masters which have access to a subset of the available drm resources. An 'owner' is a drm_master which is not leasing the objects from another drm_master, and hence 'owns' them. A 'lessee' is a drm_master which is leasing objects from some other drm_master. Each lessee holds the set of objects which it is leasing from the lessor. A 'lessor' is a drm_master which is leasing objects to another drm_master. This is the same as the owner in the current code. The set of objects any drm_master 'controls' is limited to the set of objects it leases (for lessees) or all objects (for owners). Objects not controlled by a drm_master cannot be modified through the various state manipulating ioctls, and any state reported back to user space will be edited to make them appear idle and/or unusable. For instance, connectors always report 'disconnected', while encoders report no possible crtcs or clones. The full list of lessees leasing objects from an owner (either directly, or indirectly through another lessee), can be searched from an idr in the drm_master of the owner. Changes for v2 as suggested by Daniel Vetter <daniel.vetter@ffwll.ch>: * Sub-leasing has been disabled. * BUG_ON for lock checking replaced with lockdep_assert_held * 'change' ioctl has been removed. * Leased objects can always be controlled by the lessor; the 'mask_lease' flag has been removed * Checking for leased status has been simplified, replacing the drm_lease_check function with drm_lease_held. Changes in v3, some suggested by Dave Airlie <airlied@gmail.com> * Add revocation. This allows leases to be effectively revoked by removing all of the objects they have access to. The lease itself hangs around as it's hanging off a file. * Free the leases IDR when the master is destroyed * _drm_lease_held should look at lessees, not lessor * Allow non-master files to check for lease status Changes in v4, suggested by Dave Airlie <airlied@gmail.com> * Formatting and whitespace changes Changes in v5 (airlied) * check DRIVER_MODESET before lease destroy call * check DRIVER_MODESET for lease revoke (Chris) * Use idr_mutex uniformly for all lease elements of struct drm_master.

Assignments to the crtc_id field are now done when the event is allocated, rather than when delievered. This way, delivery doesn't need to have the crtc ID available. v2: * Remove 'dev' argument from create_vblank_event It wasn't being used anyways, and if we need it in the future, we can always get it from crtc->dev. * Check for MODESETTING before looking for crtc in queue_vblank_event UMS drivers will oops if we try to get a crtc, so make sure we're modesetting before we try to find a crtc_id to fill into the event.

2017-10-21drm: Widen vblank count to 64-bits [v3]Keith Packard
This modifies the datatypes used by the vblank code to provide 64 bits of vblank count. The driver interfaces have been left using 32 bits of vblank count; all of the code necessary to widen that value for the user API was already included to handle devices returning fewer than 32-bits. This will provide the necessary datatypes for the Vulkan API. v2: * Re-write wait_vblank ioctl to ABSOLUTE sequence When an application uses the WAIT_VBLANK ioctl with RELATIVE or NEXTONMISS bits set, the target vblank interval is updated within the kernel. We need to write that target back to the ioctl buffer and update the flags bits so that if the wait is interrupted by a signal, when it is re-started, it will target precisely the same vblank count as before. * Leave driver API with 32-bit vblank count v3: * Rebase on top of Arnd Bergmann's patch which had the switch to ktime_t parts.

2017-10-19drm/vc4: Fix sleeps during the IRQ handler for DSI transactions.Eric Anholt
VC4's DSI1 has a bug where the AXI connection is broken for 32-bit writes from the CPU, so we use the DMA engine to DMA 32-bit values into registers instead. That sleeps, so we can't do it from the top half. As a solution, use an interrupt thread so that all our writes happen when sleeping is is allowed. v2: Use IRQF_ONESHOT (suggested by Boris) v3: Style nitpicks.
