From 22136ff27c4e01fae81f6588033363a46c72ed8c Mon Sep 17 00:00:00 2001 From: Taimur Hassan syed.hassan@amd.com Date: Fri, 10 Nov 2023 10:15:28 -0500 Subject: [PATCH] drm/amd/display: Fix conversions between bytes and KB
[Why] There are a number of instances where we convert HostVMMinPageSize or GPUVMMinPageSize from bytes to KB by dividing (rather than multiplying) and vice versa. Additionally, in some cases, a parameter is passed through DML in KB but later checked as if it were in bytes.
