Subject: [PATCH v6 5/8] ati-vga: Fix display updates in non-32 bit modes
Date: Sat, 21 Mar 2026 17:30:16 +0100 (CET)	[thread overview]
Message-ID: <6e1b83ef3fe7a1ebc246b474eb2b0c7cd05d5deb.1774110169.git.balaton@eik.bme.hu> (raw)
In-Reply-To: <cover.1774110169.git.balaton@eik.bme.hu>

The memory_region_set_dirty used to mark changes should use stride
value in vram which is normally only the same as surface_stride in 32
bit modes. This caused missed updates in 8 and 16 bit modes.
