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. I have compile tested this with allyesconfig against x86_64, allmodconfig against i386 and a scattering of additional defconfigs of other arches.

Remove redundant #inclusions of core DRM UAPI headers (drm.h, drm_mode.h and drm_sarea.h). They are now #included via drmP.h and drm_crtc.h via a preceding patch. Without this patch and the patch to make include the UAPI headers from the core headers, after the UAPI split, the DRM C sources cannot find these UAPI headers because the DRM code relies on specific -I flags to make #include "..." work on headers in include/drm/ - but that does not work after the UAPI split without adding more -I flags.

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() ...
| * workqueue: deprecate flush[_delayed]_work_sync()Tejun Heo2012-08-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | flush[_delayed]_work_sync() are now spurious. Mark them deprecated and convert all users to flush[_delayed]_work(). If you're cc'd and wondering what's going on: Now all workqueues are non-reentrant and the regular flushes guarantee that the work item is not pending or running on any CPU on return, so there's no reason to use the sync flushes at all and they're going away. This patch doesn't make any functional difference.

* | | drm/radeon: Prevent leak of scratch register on resume from suspendSimon Kitching2012-09-201-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Cards typically have 5-7 scratch registers; one of these is reserved for rdev->rptr_save_reg. Unfortunately the reservation is done in function r100_cp_init, which is called by all drivers except r600 - and this function is also invoked on resume from suspend. After several resumes, no scratch registers are free and graphics acceleration is disabled. Dmesg then reports either: *ERROR* radeon: cp failed to get scratch reg (-22). *ERROR* radeon: cp isn't working(-22). radeon 0000:01:00.0: failed initializing CP (-22). or: *ERROR* radeon: failed to get scratch reg (-22). *ERROR* radeon: failed testing IB on GFX ring (-22). *ERROR* ib ring test failed (-22). The chain of calls on boot for all except r600 is: radeon_init -> ... -> (rXXX_init) -> rXXX_startup -> r100_cp_init The chain of calls on resume for all except r600 is: rXXX_resume -> rXXX_startup -> r100_cp_init. R600 correctly allocates rptr_save_reg in r600_init (ie once only, not in resume). However moving the code into the init functions for all drivers means touching 4 drivers. So instead, this patch just adds a test in r100_cp_init to avoid reallocating on resume. As the rdev structure is allocated via kzalloc in radeon_driver_load_kms, and zero is not a valid registerid, zero safely implies not-yet-allocated.

* | drm/radeon: fix checking of MSAA renderbuffers on r600-r700Marek Olšák2012-08-201-5/+6
| | | | | | | | | | | | | | | | | | | | | | The MSAA checking was mostly unimplemented on r600-r700. The userspace submits GPU commands and the kernel driver computes how much memory the GPU will access and checks if it's all within buffer bounds the userspace allocated. This patch fixes the computations of the size of MSAA surfaces in memory. Signed-off-by: Marek Olšák <maraeo@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It seems we can not update the crtc scanout address. After disabling crtc, update to base address do not take effect after crtc being reenable leading to at least frame being scanout from the old crtc base address. Disabling crtc display request lead to same behavior. So after changing the vram address if we don't keep crtc disabled we will have the GPU trying to read some random system memory address with some iommu this will broke the crtc engine and will lead to broken display and iommu error message. So to avoid this, disable crtc. For flicker less boot we will need to avoid moving the vram start address.
