Subject: [PATCH 3/8] fbdev: Add Kconfig macro FB_IOMEM_HELPERS_DEFERRED
Date: Mon, 28 Aug 2023 15:14:19 +0200 [thread overview]
Message-ID: <20230828132131.29295-4-tzimmermann@suse.de> (raw)
In-Reply-To: <20230828132131.29295-1-tzimmermann@suse.de>
The new Kconfig macro FB_IOMEM_HELPERS_DEFERRED selects fbdev's
helpers for device I/O memory and deferred I/O. Drivers should
use it if they perform damage updates on device I/O memory.
