2012-12-10drm/ttm: remove no_wait_reserve, v3Maarten Lankhorst
All items on the lru list are always reservable, so this is a stupid thing to keep. Not only that, it is used in a way which would guarantee deadlocks if it were ever to be set to block on reserve. This is a lot of churn, but mostly because of the removal of the argument which can be nested arbitrarily deeply in many places. No change of code in this patch except removal of the no_wait_reserve argument, the previous patch removed the use of no_wait_reserve. v2: - Warn if -EBUSY is returned on reservation, all objects on the list should be reservable. Adjusted patch slightly due to conflicts. v3: - Focus on no_wait_reserve removal only.

2012-11-20drm: add support for monotonic vblank timestampsImre Deak
Jumps in the vblank and page flip event timestamps cause trouble for clients, so we should avoid them. The timestamp we get currently with gettimeofday can jump, so use instead monotonic timestamps. For backward compatibility use a module flag to revert back to using gettimeofday timestamps. Add also a DRM_CAP_TIMESTAMP_MONOTONIC flag that is simply a read only version of the module flag, so that clients can query this without depending on sysfs.

2012-11-20drm: don't start the poll engine in probe_single_connectorDaniel Vetter
Actually there's a reason this stuff is there, and it's called commit e58f637bb96d5a0ae0919b9998b891d1ba7e47c9 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Aug 20 09:13:36 2010 +0100 drm/kms: Add a module parameter to disable polling The idea has been that users can enable/disable polling at runtime. So the quick hack has been to just re-enable the output polling if xrandr asks for the latest state of the connectors. The problem with that hack is that when we force connectors to another state than what would be detected, we nicely ping-pong: - Userspace calls probe, gets the forced state, but polling starts again. - Polling notices that the state is actually different, wakes up userspace. - Repeat. As that commit already explains, the right fix would be to make the locking more fine-grained, so that hotplug detection on one output does not interfere with cursor updates on another crtc. But that is way too much work. So let's just safe this gross hack by caching the last-seen state of drm_kms_helper_poll for that driver, and only fire up the poll engine again if it changed from off to on. v2: Fixup the edge detection of drm_kms_helper_poll.

2012-11-20drm: handle HPD and polled connectors separatelyDaniel Vetter
Instead of reusing the polling code for hpd handling, split them up. This has a few consequences: - Don't touch HPD capable connectors in the poll loop. - Only touch HPD capable connectors in drm_helper_hpd_irq_event. - We could run the HPD handling directly (because all callers already use their own work item), but for easier bisect that happens in it's own patch. The ultimate goal is that drivers grow some smarts about which connectors have received a hotplug event and only call the detect code of that connector. But that's a second step. v2: s/hdp/hpd/, noticed by Adam Jackson. I can't type. v3: Split out the work item removal as requested by Dave Airlie. This results in a temporary mode_config.hpd_irq_work item to keep things the same. v4: In the hpd_irq_event handler don't bail out if other bits than HPD are set. This is useful where e.g. hpd is unreliably, but mostly works. Drivers can then set both HPD and POLL flags, and users get the best of both worlds: Quick hotplug feedback if the hpd works, but still reliable detection with the polling. The poll loop already works the same, and doesn't bail if HPD is set.

2012-10-22drm: extract dp link train delay functions from radeonDaniel Vetter
This requires a few changes since that dpcd value is above the range currently cached by radeon. I've check the dp specs, and above 0xf there's a big gap and nothing that looks like we should cache it while a given device is plugged in. It's also the same value that i915.ko uses. Hence extend the various dpcd arrays in the radeon driver, use proper symbolic constants where applicable (one place overallocated the dpcd array to 25 bytes). Then also drop the rd_interval cache - radeon_dp_link_train_init re-reads the dpcd block, so the values we'll consume in train_cr and train_ce will always be fresh. To avoid needless diff-churn, #define the old size of dpcd as the new one and keep it around. v2: Alex Deucher noticed one place where I've forgotten to replace 8 with DP_RECEIVER_CAP_SIZE.

2012-10-17UAPI: Remove empty non-UAPI Kbuild filesDavid Howells
Remove non-UAPI Kbuild files that have become empty as a result of UAPI disintegration. They used to have only header-y lines in them and those have now moved to the Kbuild files in the corresponding uapi/ directories. Possibly these should not be removed but rather have a comment inserted to say they are intentionally left blank. This would make it easier to add generated header lines in future without having to restore the infrastructure. Note that at this point not all the UAPI disintegration parts have been merged, so it is likely that more empty Kbuild files will turn up. It is probably necessary to make the files non-empty to prevent the patch program from automatically deleting them when it reduces them to nothing. Signed-off-by: David Howells <dhowells@redhat.com>

Pull drm merge (part 1) from Dave Airlie: "So first of all my tree and uapi stuff has a conflict mess, its my fault as the nouveau stuff didn't hit -next as were trying to rebase regressions out of it before we merged. Highlights: - SH mobile modesetting driver and associated helpers - some DRM core documentation - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write combined pte writing, ilk rc6 support, - nouveau: major driver rework into a hw core driver, makes features like SLI a lot saner to implement, - psb: add eDP/DP support for Cedarview - radeon: 2 layer page tables, async VM pte updates, better PLL selection for > 2 screens, better ACPI interactions The rest is general grab bag of fixes. So why part 1? well I have the exynos pull req which came in a bit late but was waiting for me to do something they shouldn't have and it looks fairly safe, and David Howells has some more header cleanups he'd like me to pull, that seem like a good idea, but I'd like to get this merge out of the way so -next dosen't get blocked."

git://git.infradead.org/users/dhowells/linux-headers Pull preparatory patches for user API disintegration from David Howells: "The patches herein prepare for the extraction of the Userspace API bits from the various header files named in the Kbuild files. New subdirectories are created under either include/uapi/ or arch/x/include/uapi/ that correspond to the subdirectory containing that file under include/ or arch/x/include/. The new subdirs under the uapi/ directory are populated with Kbuild files that mostly do nothing at this time. Further patches will disintegrate the headers in each original directory and fill in the Kbuild files as they do it. These patches also: (1) fix up #inclusions of "foo.h" rather than <foo.h>. (2) Remove some redundant #includes from the DRM code. (3) Make the kernel build infrastructure handle Kbuild files both in the old places and the new UAPI place that both specify headers to be exported. (4) Fix some kernel tools that #include kernel headers during their build.

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull user namespace changes from Eric Biederman: "This is a mostly modest set of changes to enable basic user namespace support. This allows the code to code to compile with user namespaces enabled and removes the assumption there is only the initial user namespace. Everything is converted except for the most complex of the filesystems: autofs4, 9p, afs, ceph, cifs, coda, fuse, gfs2, ncpfs, nfs, ocfs2 and xfs as those patches need a bit more review. The strategy is to push kuid_t and kgid_t values are far down into subsystems and filesystems as reasonable. Leaving the make_kuid and from_kuid operations to happen at the edge of userspace, as the values come off the disk, and as the values come in from the network. Letting compile type incompatible compile errors (present when user namespaces are enabled) guide me to find the issues. The most tricky areas have been the places where we had an implicit union of uid and gid values and were storing them in an unsigned int. Those places were converted into explicit unions. I made certain to handle those places with simple trivial patches. Out of that work I discovered we have generic interfaces for storing quota by projid. I had never heard of the project identifiers before. Adding full user namespace support for project identifiers accounts for most of the code size growth in my git tree. Ultimately there will be work to relax privlige checks from "capable(FOO)" to "ns_capable(user_ns, FOO)" where it is safe allowing root in a user names to do those things that today we only forbid to non-root users because it will confuse suid root applications. While I was pushing kuid_t and kgid_t changes deep into the audit code I made a few other cleanups. I capitalized on the fact we process netlink messages in the context of the message sender. I removed usage of NETLINK_CRED, and started directly using current->tty. Some of these patches have also made it into maintainer trees, with no problems from identical code from different trees showing up in linux-next. After reading through all of this code I feel like I might be able to win a game of kernel trivial pursuit."
