Subject: [PATCH 1/2] drm/amd/display: Expose support for xBGR ordered fp16 formats.
Date: Fri, 15 May 2020 07:19:23 +0200	[thread overview]
Message-ID: <20200515051924.12331-2-mario.kleiner.de@gmail.com> (raw)
In-Reply-To: <20200515051924.12331-1-mario.kleiner.de@gmail.com>

Expose support for DRM_FORMAT_ABGR16161616F and
DRM_FORMAT_XBGR16161616F to the DRM core, complementing
the already existing xRGB ordered fp16 formats.

These are especially useful for creating presentable
swapchains in Vulkan for VK_FORMAT_R16G16B16A16_SFLOAT.
