this is to fix fatal page fault error that occured if: job is signaled/released after its timeout work is already put to the global queue (in this case the cancel_delayed_work will return false), which will lead to NX-protection error page fault during job_timeout_func. Signed-off-by:

original time out detect routine is incorrect, cuz it measures the gap from job scheduled, but we should only measure the gap from processed by hw. Signed-off-by:

the mirror_list will be used for later time out detect feature. This is needed to properly detect a GPU timeout with the scheduler. Signed-off-by:

for those jobs submitted through scheduler, do not free it immediately after scheduled, instead free it in global workqueue by its sched fence signaling callback function. v2: call uf's bo_undef after job_run() call job's sync free after job_run() no static inline __amdgpu_job_free() anymore, just use kfree(job) to replace it.

In some cases, like when freezing for hibernation, we need to be able to force hard reset even if no engine are stuck. This patch add a bool option to current asic reset callback to allow to force hard reset on asic that supports it. Reviewed-by:

This match the exact same control flow as existing code. It just use goto instead of multiple levels of if/else. It also clarify early initialization failures by clearing rdev->has_vce doing so does not change end result from hardware point of view, it only avoids printing more error messages down the line and thus only the original error is reported.

This adds very rudimentary TCON (timing controller for raw LCD displays) support to enable the bypass mode in order to use the DCU controller on Freescale/NXP Vybrid SoC's. Additionally the register clock and pixel clock has been separated, but are currently still enabled and disabled pairwise. Other than that, fixes and cleanups accross the driver. * 'for-next' of http://git.agner.ch/git/linux-drm-fsl-dcu: drm/fsl-dcu: increment version and date drm/fsl-dcu: implement lastclose callback drm/fsl-dcu: disable output polling on driver unload drm/fsl-dcu: deallocate fbdev CMA on unload drm/fsl-dcu: use variable name dev for struct drm_device drm/fsl-dcu: handle missing panel gracefully drm/fsl-dcu: detach panel on destroy drm/layerscape: reduce excessive stack usage drm/fsl-dcu: add TCON driver drm/fsl-dcu: use common clock framework for pixel clock divider drm/fsl-dcu: add extra clock for pixel clock drm/fsl-dcu: disable clock on initialization failure and remove

Merge tag 'sun4i-drm-for-4.7' of https://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux into drm-next Allwinner DRM driver for 4.7 This pull request introduces the sun4i driver, meant to be used on the older Allwinner SoCs (A10, A13, A20, A23, A31 and A33). It currently supports only the A13, which has one of the simplest video pipeline. Support for other video components and SoCs will be added eventually. It supports only a RGB or composite output. It doesn't do HDMI, VGA, LVDS or power management yet, but that will come in time as well. * tag 'sun4i-drm-for-4.7' of https://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux: MAINTAINERS: Add a maintainer for the Allwinner DRM driver drm: sun4i: tv: Add NTSC output standard drm: sun4i: tv: Add PAL output standard drm: sun4i: Add composite output drm: sun4i: Add RGB output drm: Add Allwinner A10 Display Engine support drm: sun4i: Add DT bindings documentation drm: fb: Add seq_file definition

Some Allwinner SoCs have an IP called the TV encoder that is used to output composite and VGA signals. In such a case, we need to use the second TCON channel. Add support for that TV encoder. Reviewed-by:

One of the A10 display pipeline possible output is an RGB interface to drive LCD panels directly. This is done through the first channel of the TCON that will output our video signals directly. Reviewed-by:

The Allwinner A10 and subsequent SoCs share the same display pipeline, with variations in the number of controllers (1 or 2), or the presence or not of some output (HDMI, TV, VGA) or not. Add a driver with a limited set of features for now, and we will hopefully support all of them eventually Reviewed-by:

Need to move the free function around a bit, but otherwise mostly just removing code. Specifically we can nuke all the _locked variants since the weak idr reference is now protected by the idr_mutex, which we never hold anywhere expect in the lookup/reg/unreg functions. And those never call anything else. Another benefit of this is that this patch switches the weak reference logic from kref_put_mutex to kref_get_unless_zero. And the later is in general more flexible wrt accomodating multiple weak references protected by different locks, which might or might not come handy eventually. But one consequence of that switch is that we need to acquire the blob_lock from the free function for the list_del calls. That's a bit tricky to pull off, but works well if we pick the exact same scheme as is already used for framebuffers. Most important changes: - filp list is maintainer by create/destroy_blob ioctls directly (already the case, so we can just remove the redundant list_del from the free function). - filp close handler walks the filp-private list lockless - works because we know no one else can access it. I copied the same comment from the fb code over to explain this. - Otherwise we need to sufficiently restrict blob_lock critical sections to avoid all the unreference calls. Easy to do once the blob_lock only protects the list, and no longer the weak reference. Cc: Dave Airlie <airlied@gmail.com> Cc: Daniel Stone <daniels@collabora.com> Signed-off-by:
