linux-stable.git/drivers/tty/vt, branch linux-2.6.37.y Linux kernel stable tree vt: fix issue when fbcon wants to takeover a second time. 2011-02-24T22:54:25+00:00 Dave Airlie airlied@redhat.com 2011-01-06T23:57:41+00:00 385979a2a621ab3c0d740d552ad243f82697cd48 commit c55c63c6539499379ab4a7e8a5c0f857351fb946 upstream. With framebuffer handover and multiple GPUs, we get into a position where the fbcon unbinds the vesafb framebuffer for GPU 1, but we still have a radeon framebuffer bound from GPU 0, so we don't unregister the console driver. Then when we tried to bind the new radeon framebuffer for GPU1 we never get to the bind call as we fail due to the console being registered already. This changes the return value to -EBUSY when the driver is already registered and continues to bind for -EBUSY.

commit c55c63c6539499379ab4a7e8a5c0f857351fb946 upstream.

With framebuffer handover and multiple GPUs, we get into a
position where the fbcon unbinds the vesafb framebuffer for GPU 1,
but we still have a radeon framebuffer bound from GPU 0, so
we don't unregister the console driver. Then when we tried to bind
the new radeon framebuffer for GPU1 we never get to the bind
call as we fail due to the console being registered already.

This changes the return value to -EBUSY when the driver is
already registered and continues to bind for -EBUSY.

vcs: make proper usage of the poll flags 2010-11-11T18:51:35+00:00 Nicolas Pitre nicolas.pitre@canonical.com 2010-11-10T06:33:12+00:00 47c344d0bd290e04c57eefdb0a721726e53bb57e Kay Sievers pointed out that usage of POLLIN is well defined by POSIX, and the current usage here doesn't follow that definition. So let's duplicate the same semantics as implemented by sysfs_poll() instead.
