Some GPUs, namely, the bifrost/g72 part on MT8183, have a second regulator for their SRAM, let's add support for that. We extend the framework in a generic manner so that we could support more than 2 regulators, if required. Signed-off-by:

Propagate bus format/flags so that the previous bridge element in the chain knows which input format the panel bridge expects. v11: * Fix a typo in the subject * Update the commit message so it's readable by itself v10: * Add changelog to the commit message v8 -> v9: * No changes v7: * Set atomic state hooks explicitly v4 -> v6: * Not part of the series v3: * Adjust things to match the new bus-format negotiation approach * Use drm_atomic_helper_bridge_propagate_bus_fmt * Don't implement ->atomic_check() (the core now takes care of bus flags propagation) v2: * Adjust things to match the new bus-format negotiation approach Signed-off-by:

The drm_bridge_funcs structure is never modified, make it const. Making it read-only can improve security as the structure contains function pointers. Signed-off-by:

We currently create an OpenGL context when opening the DRM fd if 3D is available. We may need other context types (VK,..) in the future, and the plan is to have explicit initialization for that. For explicit initialization to work, we need to factor out virtio_gpu_create_context from driver initialization. v2: Move context handle initialization too (olv) v6: Remove redundant 3D check (emil.velikov) Reviewed-by:

The panel datasheet says that the panel samples at falling edge, but does not say anything about h/v sync signals. Testing shows that if the sync signals are driven on falling edge, the picture on the panel will be slightly shifted right. Setting sync drive edge to the same as data drive edge fixes this issue.

We need to make sure that the DRM driver is fully registered before allowing the panel to be attached. Otherwise, we may trigger a hotplug event before sun4i_framebuffer_init() sets up drm->mode_config.funcs, causing a NULL pointer dereference.

Before we are going to wait for virtqueue entries becoming available call virtio_gpu_notify() to make sure the host has seen everything we've submitted. Signed-off-by:

Gerd Hoffmann authored
Drop the virtio_gpu_{disable,enable}_notify(). Add a new virtio_gpu_notify() call instead, which must be called whenever the driver wants make sure the host is notified needed. Drop automatic notification from command submission. Add virtio_gpu_notify() calls after each command query instead. This allows more fine-grained control over host notification and can move around the notify calls in subsequent patches to batch command submissions. With this in place it is also possible to make notification optional for userspace ioctls. Page flip batching goes away (temporarely). v3: - move batching to separate patches. v2: - rebase to latest drm-misc-next. - use "if (!atomic_read())". - add review & test tags. Signed-off-by: -

The last in-kernel user of the old framebuffer driver is the IM-PD1 module for the Integrator/AP. Let's implement support for this remaining user so we can migrate the last user over to DRM and delete the old FB driver. On the Integrator/AP the IM-PD1 system controller will exist alongside the common Integrator system controller so make sure to do a special lookup for the IM-PD1 syscon and make it take precedence if found. Tested on the Integrator/AP with the IM-PD1 mounted. Acked-by:
