This patch adds a kms driver for the virtio gpu. The xorg modesetting driver can handle the device just fine, the framebuffer for fbcon is there too. Qemu patches for the host side are under review currently. The pci version of the device comes in two variants: with and without vga compatibility. The former has a extra memory bar for the vga framebuffer, the later is a pure virtio device. The only concern for this driver is that in the virtio-vga case we have to kick out the firmware framebuffer. Initial revision has only 2d support, 3d (virgl) support requires some more work on the qemu side and will be added later. Signed-off-by:

This patch deinlines indirect register accessor functions. These functions perform two mmio accesses, framed by spin lock/unlock. Spin lock/unlock by itself takes more than 50 cycles in ideal case (if lock is exclusively cached on current CPU).

If we have more than one CRTCs in a group pre-associate planes 0-3 with CRTC 0 and planes 4-7 with CRTC 1 to minimize flicker occurring when the association is changed. The pre-association could be controlled by a module parameter if needed. Signed-off-by:Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

The number of CRTCs in a group is only used to implement plane initialization for now, but is also needed to implement pre-association of planes to CRTCs. Store it in the group structure instead of computing it on demand. Signed-off-by: -

Hardware planes are driven by the timing generator of the CRTC they are associated to. Changing the association requires restarting the CRTC group that the plane belongs to, resulting in flicker on the other CRTC. To avoid flicker as much as possible, try to allocate planes first from the free planes already associated with the target CRTC. If allocation fails then fall back to allocation from all free planes.

The ADV7511 is probed before its slave encoder init function associates it with an encoder. This creates a time window during which hot plug detection interrupts can occur with an encoder, resulting in a crash in the IRQ handler. Fix this by ignoring hot plug detection IRQs when no encoder is associated yet. Signed-off-by:
