From: Ayan Halder Subject: [PATCH] drm/arm/malidp: Consider rotation memory requirement in case of AFBC framebuffer Date: Fri, 9 Nov 2018 10:37:19 +0000 Message-ID: <1541759832-19211-1-git-send-email-ayan.halder@arm.com> Mime-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Return-path: Content-Language: en-US Sender: linux-kernel-owner@vger.kernel.org To: Ayan Halder , Liviu Dudau , Brian Starkey , "malidp@foss.arm.com" , "airlied@linux.ie" , "dri-devel@lists.freedesktop.org" , "linux-kernel@vger.kernel.org" Cc: nd List-Id: dri-devel@lists.freedesktop.org Rotation memory for layers is shared with AFBC decoder block. Thus one need= s to calculate rotation memory requirement in case of AFBC framebuffer. This is used later to verify if it can be sufficed by the hardware rotation memory availibility.
