ERR_INT can generate interrupts. However since most of the conditions seem quite fatal the patch opts to simply report it in error state instead of adding more complexity to the interrupt handler for little gain (the bits are sticky anyway). Signed-off-by:

In intel_dp_mode_set we OR in the exact same bits twice at the same spot. Kill one of the redundant assignments.

Given the persistence of an offset for the lifetime of an object, itis easy to contemplate how the mmap space becomes badly fragmented to the point that further allocations fail with ENOSPC. Our only recourse at this point is to try to purge the objects to release some space and reattempt the allocation. References: https://bugs.freedesktop.org/show_bug.cgi?id=39552Signed-off-by:

A pair of universally true checks that just need to be put in the right place depending on where in the patch sequence you go. Note that i915_gem_object_put_pages_gtt() already gains the BUG_ON(obj->gtt_space), but on reflection that needed to migrate to put_pages(). Signed-off-by: -

When dealing with a working set larger than the GATT, or even the mappable aperture when touching through the GTT, we end up with evicting objects only to rebind them at a new offset again later. Moving an object into and out of the GTT requires clflushing the pages, thus causing a double-clflush penalty for rebinding. To avoid having to clflush on rebinding, we can track the pages as they are evicted from the GTT and only relinquish those pages on memory pressure. As usual, if it were not for the handling of out-of-memory condition and having to manually shrink our own bo caches, it would be a net reduction of code. Alas. Note: The patch also contains a few changes to the last-hope evict_everything logic in i916_gem_execbuffer.c - we no longer try to only evict the purgeable stuff in a first try (since that's superflous and only helps in OOM corner-cases, not fragmented-gtt trashing situations). Also, the extraction of the get_pages retry loop from bind_to_gtt (and other callsites) to get_pages should imo have been a separate patch. v2: Ditch the newly added put_pages (for unbound objects only) in i915_gem_reset. A quick irc discussion hasn't revealed any important reason for this, so if we need this, I'd like to have a git blame'able explanation for it. v3: Undo the s/drm_malloc_ab/kmalloc/ in get_pages that Chris noticed.

Prep work to make Chris Wilson's unbound tracking patch a bit easier to read. Alas, I'd have preferred that moving the page allocation retry loop from bind to get_pages would have been a separate patch, too. But that looks like real work ;-) Signed-off-by:

In order for udl vmap to work properly, we need to push the object into the CPU domain before we start copying the data to the USB device. This along with the udl change avoids userspace explicit mapping to be used. v2: add a flag for userspace to query to know if Intel kernel driver can deal with the vmap flushing properly. In theory udl would need a flag also, but I intend to push the patches very close to each other and other drivers should do the right thing from the start. I've added a test to my intel-gpu-tools prime branch, however testing this is a bit messy since the only way to get udl to vmap is to rendering something. I've tested this with real code as well to make sure it works. Signed-off-by:

Yet again the too close relationship between the fb helper and the crtc helper code strikes. This time around the fb helper resets all encoder->crtc pointers to NULL before starting to set up it's own mode. Which is total bullocks, because this will clobber the existing output routing, which the new drm/i915 code depends upon to be absolutely correct. The crtc helper itself doesn't really care about that, since it disables unused encoders in a rather roundabout way anyway. Two places call drm_setup_crts: - For the initial fb config. I've auditted all current drivers, and they all allocate their encoders with kzalloc. So there's no need to clear encoder->crtc once more. - When processing hotplug events while showing the fb console. This one is a bit more tricky, but both the crtc helper code and the new drm/i915 modeset code disable encoders if their crtc is changed and that encoder isn't part of the new config. Also, both disable any disconnected outputs, too. Which only leaves encoders that are on, connected, but for some odd reason the fb helper code doesn't want to use. That would be a bug in the fb configuration selector, since it tries to light up as many outputs as possible. v2: Kill the now unused encoders variable. Acked-by:

All dvo drivers only support 2 dpms states, and our dvo driver even switches of the dvo port for anything else than DPMS_ON. Hence ditch this complexity and simply use bool enable. While reading through this code I've noticed that the mode_set function of ch7017 is a bit peculiar - it disable the lvds again, even though the crtc helper code should have done that ... This might be to work around an issue at driver load, we pretty much ignore the hw state when taking over. v2: Also do the conversion for the new ns2501 driver. Reviewed-by:

A few things need adjustement: - Change the dpms state by calling the dpms connector function and not some crtc helper internal callbacks. Otherwise this will break once we switch to our own dpms handling. - Instead of tracking and restoring intel_crtc->dpms_mode use the connector's dpms variable - the former relies on the dpms compuation rules used by the crtc helper. And it would break when the encoder is cloned and the other output has a different dpms state. But luckily no one is crazy enough for that. - Properly clear the connector -> encoder -> crtc linking, even when failing (note that the crtc helper removes the encoder -> crtc link in disabled_unused_functions for us).

Now that all affected i830M systems have the pipe A quirk set, we don't need to do any special dances in the overlay code any longer. And reading through the code I'm rather dubios that it actually does what it claims to do ... As a nice benefit this rips out a users of the crtc helper dpms callback. v2: As suggested by Chris Wilson, replace the code by an appropriate WARN to ensure that the pipe A is indeed running.

Following a report of a crash during an automount expire I found that the locking in fs/autofs4/expire.c:get_next_positive_subdir() was wrong. Not only is the locking wrong but the function is more complex than it needs to be. The function is meant to calculate (and dget) the next entry in the list of directories contained in the root of an autofs mount point (an autofs indirect mount to be precise). The main problem was that the d_lock of the owner of the list was not being taken when walking the list, which lead to list corruption under load. The only other lock that needs to be taken is against the next dentry candidate so it can be checked for usability. Signed-off-by:
