similar to: [PATCH] drm/virtio: Replace instances of reference/unreference with get/put

From: Dave Airlie <airlied at gmail.com> 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

From: Markus Elfring <elfring at users.sourceforge.net> Date: Fri, 15 Jul 2016 22:38:42 +0200 The drm_gem_object_unreference_unlocked() function tests whether its argument is NULL and then returns immediately. Thus the test around the calls is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring at users.sourceforge.net> ---

Some helper functions to manage an array of gem objects. v6: - add ticket to struct virtio_gpu_object_array. - add virtio_gpu_array_{lock,unlock}_resv helpers. - add virtio_gpu_array_add_fence helper. v5: some small optimizations (Chia-I Wu). v4: make them virtio-private instead of generic helpers.

This patch set replaces functions named {un,reference} by their {put,get} counterparts. Affected data types are struct drm_connector, struct drm_framebuffer, struct drm_gem_object, and struct drm_device. With the reference-counting functions being named {put,get}, the DRM interface is more aligned to Linux kernel nameing standard. The patch set does not change driver-internal interfaces. Thomas

Because all drivers currently use gem objects for framebuffer planes, the virtual create_handle() is not required. This change adds a struct drm_gem_object *gems[4] field to drm_framebuffer and removes create_handle() function pointer from drm_framebuffer_funcs. The corresponding *_create_handle() function is removed from each driver. In many cases this change eliminates a struct *_framebuffer

virtio-gpu basically needs a sg_table for the bo, to tell the host where the backing pages for the object are. So the gem shmem helpers are a perfect fit. Some drm_gem_object_funcs need thin wrappers to update the host state, but otherwise the helpers handle everything just fine. Once the fencing was sorted the switch was surprisingly easy and for the most part just removing the ttm code. v4:

This patch set replaces the occurrences of drm_*_reference() and drm_*_unreference() with the new drm_*_get() and drm_*_put() functions. All patches in the series do the same thing, converting to the new APIs. I created patches per DRM driver as suggested by Daniel Vetter. Background: In the kernel, reference counting APIs use *_get(), *_put() style naming to reference-count the objects. But DRM
