[Qemu-devel] [PATCH v3 3/7] sm501: Use values from the pitch register for 2D operations |
Date: |
Wed, 04 Jul 2018 11:40:58 +0200 |
Before, crt_h_total was used for src_width and dst_width. This is a
property of the current display setting and not relevant for the 2D
operation that also can be done off-screen. The pitch register's purpose
is to describe line pitch relevant of the 2D operation.
