@ -589,3 +589,26 @@ Why: Useful in 2003, implementation is a hack.
Generally invoked by accident today.
Seen as doing more harm than good.
Who: Len Brown <len.brown@intel.com>
----------------------------
What: video4linux /dev/vtx teletext API support
When: 2.6.35
Files: drivers/media/video/saa5246a.c drivers/media/video/saa5249.c
include/linux/videotext.h
Why: The vtx device nodes have been superseded by vbi device nodes
for many years. No applications exist that use the vtx support.
Of the two i2c drivers that actually support this API the saa5249
has been impossible to use for a year now and no known hardware
that supports this device exists. The saa5246a is theoretically
supported by the old mxb boards, but it never actually worked.
In summary: there is no hardware that can use this API and there
are no applications actually implementing this API.
The vtx support still reserves minors 192-223 and we would really
like to reuse those for upcoming new functionality. In the unlikely
event that new hardware appears that wants to use the functionality
provided by the vtx API, then that functionality should be build
around the sliced VBI API instead.

to NULL in remove() or if probe() failed anymore. The i2c-core does this
automatically on these occasions. Those are also the only times the core will
touch this field.

Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
require workarounds. Without workarounds the system may hang
unexpectedly. For more information please refer to the gas
-mfix-loongson2f-nop and -mfix-loongson2f-jump options.
Loongson 2F03 and later have fixed these issues and no workarounds
are needed. The workarounds have no significant side effect on them
but may decrease the performance of the system so this option should
be disabled unless the kernel is intended to be run on 2F01 or 2F02
systems.
If unsure, please say Y.
