| * | drm/exynos: Disable plane when releasedInki Dae2012-10-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | this patch ensures that each plane connected to encoder is disabled when released, by adding disable callback function of encoder helper we had faced with one issue that invalid memory is accessed by dma once drm is released and then the dma is turned on again. actually, in our case, page fault was incurred with iommu. the reason is that a gem buffer accessed by the dma is also released once drm is released. so this patch would fix this issue ensuring the dma is disabled when released.

| * | drm/exynos: check NV12M format specific to Exynos properlyInki Dae2012-10-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | this patch adds buf_cnt variable in exynos_drm_fb structure and that means a buffer count to drm framebuffer and also adds two functions to get/set the buffer count from/to exynos_drm_fb structure. if pixel format is not DRM_FORMAT_NV12MT then it gets a buffer count to drm framebuffer refering to mode_cmd->handles and offsets. but when booted, the buffer count will always be 1 because pixel format of console framebuffer is RGB format.

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."

| * | drm: refcnt drm_framebuffer (v4.1)Rob Clark2012-10-02

This is a problem that shows up when userspace is using a drm plane to implement a hw cursor.. making overlay disable synchronous causes a performance problem when x11 is rapidly enabling/disabling the hw cursor. But not making it synchronous opens up a race condition for crashing if userspace turns around and immediately deletes the fb. Refcnt'ing the fb makes it possible to solve this problem. v1: original v2: add drm_framebuffer_remove() which is called in all paths where fb->funcs->destroy() was directly called before. This cleans up the CRTCs/planes that the fb was attached to. You should only directly use drm_framebuffer_unreference() if you are also using drm_framebuffer_reference() to keep a ref to the fb. v3: add comment explaining the fb refcount v4: remove duplicate 'list_del(&fb->filp_head)' [airlied: v4.1: fix local rejection] Signed-off-by: Rob Clark <rob@ti.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

I've tried to fix this by making the conflict explicit by merging a version for next with: commit 3cce574f0190dd149472059fb69267cf83d290f9 Author: Wang Xingchao <xingchao.wang@intel.com> Date: Thu Sep 13 11:19:00 2012 +0800 drm/i915: HDMI - Clear Audio Enable bit for Hot Plug unconditionally But that failed to solve the entire problem. To avoid pushing out further -nightly branch to our QA where this is broken, do the backmerge and manually add the stuff git adds to -next from the patch in -fixes. Note that this doesn't show up in git's merge diff (and hence is also not handled by git rerere), which adds to the reasons why I'd like to fix this with a verbose backmerge.

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Neither the drm core nor any of the drivers really need the raw_edid field of struct drm_display_info for anything. Instead of being useful, it creates confusion about who is responsible for freeing the memory it points to and setting the field to NULL afterwards, leading to memory leaks and dangling pointers. Remove the raw_edid field, and fix drivers as necessary.

(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.

A lot of activities this round including considerable API and behavior cleanups. * delayed_work combines a timer and a work item. The handling of the timer part has always been a bit clunky leading to confusing cancelation API with weird corner-case behaviors. delayed_work is updated to use new IRQ safe timer and cancelation now works as expected. * Another deficiency of delayed_work was lack of the counterpart of mod_timer() which led to cancel+queue combinations or open-coded timer+work usages. mod_delayed_work[_on]() are added. These two delayed_work changes make delayed_work provide interface and behave like timer which is executed with process context. * A work item could be executed concurrently on multiple CPUs, which is rather unintuitive and made flush_work() behavior confusing and half-broken under certain circumstances. This problem doesn't exist for non-reentrant workqueues. While non-reentrancy check isn't free, the overhead is incurred only when a work item bounces across different CPUs and even in simulated pathological scenario the overhead isn't too high. All workqueues are made non-reentrant. This removes the distinction between flush_[delayed_]work() and flush_[delayed_]_work_sync(). The former is now as strong as the latter and the specified work item is guaranteed to have finished execution of any previous queueing on return. * In addition to the various bug fixes, Lai redid and simplified CPU hotplug handling significantly. * Joonsoo introduced system_highpri_wq and used it during CPU hotplug. There are two merge commits - one to pull in IRQ safe timer from tip/timers/core and the other to pull in CPU hotplug fixes from wq/for-3.6-fixes as Lai's hotplug restructuring depended on them." Fixed a number of trivial conflicts, but the more interesting conflicts were silent ones where the deprecated interfaces had been used by new code in the merge window, and thus didn't cause any real data conflicts. Tejun pointed out a few of them, I fixed a couple more. * 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: (46 commits) workqueue: remove spurious WARN_ON_ONCE(in_irq()) from try_to_grab_pending() workqueue: use cwq_set_max_active() helper for workqueue_set_max_active() workqueue: introduce cwq_set_max_active() helper for thaw_workqueues() workqueue: remove @delayed from cwq_dec_nr_in_flight() workqueue: fix possible stall on try_to_grab_pending() of a delayed work item workqueue: use hotcpu_notifier() for workqueue_cpu_down_callback() workqueue: use __cpuinit instead of __devinit for cpu callbacks workqueue: rename manager_mutex to assoc_mutex workqueue: WORKER_REBIND is no longer necessary for idle rebinding workqueue: WORKER_REBIND is no longer necessary for busy rebinding workqueue: reimplement idle worker rebinding workqueue: deprecate __cancel_delayed_work() workqueue: reimplement cancel_delayed_work() using try_to_grab_pending() workqueue: use mod_delayed_work() instead of __cancel + queue workqueue: use irqsafe timer for delayed_work workqueue: clean up delayed_work initializers and add missing one workqueue: make deferrable delayed_work initializer names consistent workqueue: cosmetic whitespace updates for macro definitions workqueue: deprecate system_nrt[_freezable]_wq workqueue: deprecate flush[_delayed]_work_sync() ...

Mark them deprecated and convert all users to flush[_delayed]_work().

* | drm: use drm_compat_ioctl for 32-bit appsKeith Packard2012-09-05
|/ | | | | | | | | | | | | | | Most of the DRM drivers appear to be missing the .compat_ioctl file operation entry necessary for 32-bit application compatibility. This patch uses drm_compat_ioctl for all drivers which don't have their own, and which are using drm_ioctl for .unlocked_ioctl. This leaves drivers/gpu/drm/psb/psb_drv.c unchanged; it has a custom .unlocked_ioctl and will presumably need a custom .compat_ioctl as well.
