docs: fb: convert docs to ReST and rename to *.rst

2019-06-14T20:21:11+00:00

The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings. Also, removed the Maintained by, as requested by Geert.

udlfb: Enable fb_defio by default

2011-08-24T10:12:33+00:00

Enables page fault based detection of mmap writes to the framebuffer, which allows standard fbdev apps (like the generic fbdev xorg driver) to work on DisplayLink devices. Not all bugs are shaken out of the fb_defio path of udlfb, but it's tantalizingly close, so this seems a good time to enable by default. Alternatively, option can be disabled when running with an xorg driver that can more directly communicate damaged regions of the framebuffer via IOCTL. This is a simpler, higher perf option, when available. Signed-off-by: Bernie Thompson Signed-off-by: Florian Tobias Schandinat

udlfb: Add module option to do without shadow framebuffer

2011-08-24T10:10:44+00:00

By default, udlfb allocates a 2nd buffer to shadow what's across the bus on the USB device. It can operate without this shadow, but then it cannot tell which pixels have changed, and must send all. Saves host memory, but worsens the USB 2.0 bus bottleneck. This option allows users in very low memory situations (e.g. bifferboard) to optionally turn off this shadow framebuffer.

fbdev: move udlfb out of staging.

2010-11-16T05:00:24+00:00

udlfb has undergone a fair bit of cleanup recently and is effectively at the point where it can be liberated from staging purgatory and promoted to a real driver. The outstanding cleanups are all minor, with some of them dependent on drivers/video headers, so these will be done incrementally from udlfb's new home.
