Cancel the output polling work proc before acquiring the struct mutex to avoid acquiring the work proc mutex with the struct mutex held. This avoids inverting the lock order seen when the work proc runs. Signed-off-by:

Move the access control up from the fast paths, which are no longer universally taken first, up into the caller. This then duplicates some sanity checking along the slow paths, but is much simpler. Tracked as CVE-2010-2962. Reported-by:

Instead of waiting for the display line value to settle, we can simply wait for the pipe configuration register 'state' bit to turn off. Contrarywise, disabling the plane will not cause the display line value to stop changing, so instead we wait for the vblank interrupt bit to get set. And, we only do this when we're not about to wait for the pipe to turn off. Signed-off-by:

While the display port is in training mode, vblank interrupts don't occur. Because we have to wait for the display port output to turn on before starting the training sequence, enable the output in 'normal' mode so that we can tell when a vblank has occurred, then start the training sequence.

Extend the error handling code with operations found in other nearby error handling code A simplified version of the sematic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ @r@ statement S1,S2,S3; constant C1,C2,C3; @@ *if (...) {... S1 return -C1;} ... *if (...) {... when != S1 return -C2;} ... *if (...) {... S1 return -C3;} // </smpl> Signed-off-by:

The return from move_to_gtt_domain() may indicate a pending signal which needs to handled as opposed to an actual error, for instance, so report the original return value rather than forcing an EINVAL. Signed-off-by:

The issue is that we may become stuck executing a long running shader and continually attempt to reset the GPU. (Or maybe we tickle some bug and need to break the vicious cycle.) So if we are detect a second hang within 5 seconds, give up trying to programme the GPU and report it wedged. Signed-off-by: -

Added a function that sets the LVDS values to default settings. This will be called by intel_init_bios before checking for the VBT (video BIOS table). The default values are thus loaded regardless of whether a VBT is found. The default settings in each parse function have been moved to the new function. This consolidates all the default settings into one place. The default dither bit value has been changed from 0 to 1. We can assume that display devices will want dithering enabled. Signed-off-by:

The IPS driver needs to know the current power consumption of the GMCH in order to make decisions about when to increase or decrease the CPU and/or GPU power envelope. So fix up the divisions to save the results so the numbers are actually correct (contrary to some earlier comments and code, these functions do not modify the first argument and use it for the result).
