From 48d45fac3940347becd290b96b2fc6d5ad8171f7 Mon Sep 17 00:00:00 2001 From: Jacek Lawrynowicz Date: Tue, 31 Oct 2023 08:31:55 +0100 Subject: accel/ivpu: Remove support for uncached buffers Usages of DRM_IVPU_BO_UNCACHED should be replaced by DRM_IVPU_BO_WC. There is no functional benefit from DRM_IVPU_BO_UNCACHED if these buffers are never mapped to host VM. This allows to cut the buffer handling code in the kernel driver by half. Usage of DRM_IVPU_BO_UNCACHED buffers was removed from user-space driver and will not be part of first UMD release.
