[PATCH v5] drm/pl111: Initial drm/kms driver for pl111

From: Tom Cooksey This is a modesetting driver for the pl111 CLCD display controller found on various ARM platforms such as the Versatile Express. The driver has only been tested on the bcm911360_entphn platform so far, with PRIME-based buffer sharing between vc4 and clcd. It reuses the existing

[PATCH 3/3] drm/vc4: Add support for dma-buf fencing.

This is needed for proper synchronization with display on another DRM device (pl111 or tinydrm) with buffers produced by vc4 V3D. Fixes the new igt vc4_dmabuf_poll testcase, and rendering of one of the glmark2 desktop tests on pl111+vc4. This doesn't yet introduce waits on other device's fences b

[PATCH 1/8] sync_file: add type/flags to sync file object creation.

From: Dave Airlie This allows us to create sync files with different semantics, and clearly define the interoperation between them it also provides flags to allow for tweaks on those semantics. This provides a validation interface for drivers that accept types from userspace so they can return E

From: Dave Airlie This patch allows the underlying fence in a sync_file to be changed or set to NULL. This isn't currently required but for Vulkan semaphores we need to be able to swap and reset the fence. In order to faciliate this, it uses rcu to protect the fence, along with a new mutex. The
