Noticed this as I was skimming through, if we fail to allocate memory for cli we'll end up returning without dropping the runtime PM ref we got. Additionally, we'll even return the wrong return code! (ret most likely will == 0 here, we want -ENOMEM). Signed-off-by:

With instantaneous high precision vblank timestamping that updates at leading edge of vblank, the emulated "hw vblank counter" from vblank timestamping, which increments at leading edge of vblank, and reliable page flip execution and completion at leading edge of vblank, we should meet the requirements for fast/ immediate vblank irq disable/enable. This is only allowed on nv50+ gpu's, ie. the ones with atomic modesetting. One requirement for immediate vblank disable is that high precision vblank timestamping works reliably all the time on all connectors. This is not the case on all pre-nv50 parts for analog VGA outputs, where we currently don't always have support for scanout position queries and therefore fall back to vblank interrupt timestamping. The implementation in nv04_head_state() does not return valid values for vblanks, vtotal, hblanks, htotal for VGA outputs on all cards, but those are needed for scanout position queries. Testing on Linux-4.12-rc5 + drm-next on a GeForce 9500 GT (NV G96) with timing measurement equipment indicates this works fine, so allow immediate vblank disable for power saving. For debugging in case of unexpected trouble, booting with kernel cmdline option drm.vblankoffdelay=0 (or echo 0 > /sys/module/drm/parameters/vblankoffdelay) would keep vblank irqs permanently on to approximate old behavior.

A patchset worked out together with Peter Zijlstra. Ingo is OK with taking it through the DRM tree: This is a small fallout from a work to allow batching WW mutex locks and unlocks. Our Wound-Wait mutexes actually don't use the Wound-Wait algorithm but the Wait-Die algorithm. One could perhaps rename those mutexes tree-wide to "Wait-Die mutexes" or "Deadlock Avoidance mutexes". Another approach suggested here is to implement also the "Wound-Wait" algorithm as a per-WW-class choice, as it has advantages in some cases. See for example http://www.mathcs.emory.edu/~cheung/Courses/554/Syllabus/8-recv+serial/deadlock-compare.html Now Wound-Wait is a preemptive algorithm, and the preemption is implemented using a lazy scheme: If a wounded transaction is about to go to sleep on a contended WW mutex, we return -EDEADLK. That is sufficient for deadlock prevention. Since with WW mutexes we also require the aborted transaction to sleep waiting to lock the WW mutex it was aborted on, this choice also provides a suitable WW mutex to sleep on. If we were to return -EDEADLK on the first WW mutex lock after the transaction was wounded whether the WW mutex was contended or not, the transaction might frequently be restarted without a wait, which is far from optimal. Note also that with the lazy preemption scheme, contrary to Wait-Die there will be no rollbacks on lock contention of locks held by a transaction that has completed its locking sequence. The modeset locks are then changed from Wait-Die to Wound-Wait since the typical locking pattern of those locks very well matches the criterion for a substantial reduction in the number of rollbacks. For reservation objects, the benefit is more unclear at this point and they remain using Wait-Die. Signed-off-by:

Add suffix ULL to constant 5 and cast variables target_pix_clk_khz and feedback_divider to uint64_t in order to avoid multiple potential integer overflows and give the compiler complete information about the proper arithmetic to use. Notice that such constant and variables are used in contexts that expect expressions of type uint64_t (64 bits, unsigned). The current casts to uint64_t effectively apply to each expression as a whole, but they do not prevent them from being evaluated using 32-bit arithmetic instead of 64-bit arithmetic. Also, once the expressions are properly evaluated using 64-bit arithmentic, there is no need for the parentheses that enclose them.
