The runqueue worker currently issues a get() when a new node is processed, and a put() once a node is completed. The corresponding suspend and resume calls currently only do clock gating, but with the upcoming introduction of IOMMU runpm also the corresponding IOMMU domain gets enabled (for get()) and disabled (for put()). This introduces performance regressions with we mitigate here. Switch PM runtime to autosuspend, such that clock gating and IOMMU control only happens when the engine is idle for a 'long' time.

While the engine works on a runqueue node it does memory access to the buffers associated with that node. Make sure that the engine is idle when g2d_close() and/or g2d_remove() are called, i.e. buffer associated with the process (for g2d_close()), or all buffers (for g2d_remove()) can be safely be unmapped. We have to take into account that the engine might be in an undefined state, i.e. it hangs and doesn't become idle. In this case, we issue a hardware reset to return the hardware and the driver context into a proper state. Signed-off-by:

The driver might be closed (and/or removed) while there are still nodes queued for processing. Make sure to remove these nodes, which means all of them in the case of g2d_remove() and only those belonging to the corresponding process in g2d_close(). Signed-off-by:

This reverts commit b05984e2. The change, i.e. merging the sleep and runpm operations, produces a deadlock situation: (1) exynos_g2d_exec_ioctl() prepares a runqueue node and calls g2d_exec_runqueue() (2) g2d_exec_runqueue() calls g2d_dma_start() which gets runtime PM sync (3) runtime PM core calls g2d_runtime_resume() (4) g2d_runtime_resume() calls g2d_exec_runqueue(), which loops back to (2) Due to mutexes that are in place, a deadlock situation is created.

We get 1 warning when building kernel with W=1: drivers/gpu/drm/exynos/exynos_dp.c:46:5: warning: no previous prototype for 'exynos_dp_crtc_clock_enable' [-Wmissing-prototypes] In fact, this function is only used in the file in which it is declared and don't need a declaration, but can be made static. So this patch marks it 'static'. Signed-off-by:

In case of some platforms fimd clocks can be configured to very low values, as a result refresh rate can be very low and driver/drm-core will timeout waiting for vblanks, it will result in premature removal of framebuffers and will cause oopses. The patch adds atomic_check callback to fimd to prevent setting such modes. Reported-by:

Exynos DRM devices update their registers at vblank time. Exynos-DRM uses custom mechanism to wait for vblank. This mechanism is error prone - variables are not updated atomically. As a result in certain circumstances user space can try to free buffers which are still in use by hardware, in such cases IOMMU can throw OOPS. The patch instead of fixing the mechanism replaces it with drm core helper. Signed-off-by:

VIDI driver uses fake vblank handler to generate vblank events. It was implemented using worker which slept for vblank time, additionally it did not work if there were no page flips. The patch replaces it with timer, uses drm_crtc_vblank_(on|off) helpers to manage it and fixes behavior for non-page-flip cases. This change allows further improvements of vblank in exynos-drm framework. Signed-off-by:
