Merge tag 'exynos-drm-next-for-v4.18-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next Add more HW overlays support - It enables hardware overlay number 4 and 5. For this, this patch series adds required clocks. Several fixups - Fix default value of zpos according to real hardware overlay number. - Fix error value of exynos_Drm_crtc_get_by_type function correctly. - Fix static checker warning of scaler_task_done function. - Fix signedness bug in fimc_setup_clocks function. One cleanup - Disable framedone interrupt of DSI device which is not required. Signed-off-by:

To free the fence from the amdgpu_fence_slab, need twice call_rcu, to avoid the amdgpu_fence_slab_fini call kmem_cache_destroy(amdgpu_fence_slab) before kmem_cache_free(amdgpu_fence_slab, fence), add rcu_barrier after drm_sched_entity_fini.

DSI driver is not really interested in this interrupt. It causes only unnecessary code execution of interrupt handler and could possibly cause FIFO overflow - as it triggers DSI interrupt handler to process next DSI transfer.

First of all it's already being called from the display code from amd_ip_funcs.suspend/resume hooks. Second of all, the place in amdgpu_device_gpu_recover it's being called is wrong for GPU stalls since it is called BEFORE we cancel and force completion of all in flight jobs which were not yet processed. So, as Bas pointed in the ticket we will try to wait for fence in amdgpu_pm_compute_clocks but the pipe is hanged so we end up in deadlock. v2: remove unused variable Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=106500Signed-off-by:

Enable support for 2 more hardware windows. This require enabling a few more clocks and set proper plane type for all windows. In the new configuration primary plane uses hardware window no 3 and cursor uses window no 5. The remaining hardware windows are used for overlays. This gives us an overlay plane both below and above primary plane for both Decon and DeconTV (which uses hardware window nr 0 for background). Signed-off-by:

Merge tag 'exynos-drm-next-for-v4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into exynos-drm-next - Add S5PV210 FIMD variant support. - Add IPP v2 framework. . it is a rewritten version of the Exynos mem-to-mem image processing framework which supprts color space conversion, image up/down-scaling and rotation. This new version replaces existing userspace API with new easy-to-use and simple ones so we have already applied the use of these API to real user, Tizen Platform[1], and also makes existing Scaler, FIMC, GScaler and Rotator drivers to use IPP v2 core API. And below are patch lists we have applied to a real user, https://git.tizen.org/cgit/platform/adaptation/samsung_exynos/libtdm-exynos/log/?h=tizen&qt=grep&q=ipp https://git.tizen.org/cgit/platform/adaptation/samsung_exynos/libtdm-exynos/commit/?h=tizen&id=b59be207365d10efd489e6f71c8a045b558c44fe https://git.tizen.org/cgit/platform/kernel/linux-exynos/log/?h=tizen&qt=grep&q=ipp TDM(Tizen Display Manager) is a Display HAL for Tizen platform. Ps. Only real user using IPP API is Tizen. [1] https://www.tizen.org/ - Two cleanups . One is to just remove mode_set callback from MIPI-DSI driver because drm_display_mode data is already available from crtc atomic state. . And other is to just use new return type, vm_fault_t for page fault handler.

drm/tegra: Changes for v4.18-rc1 This set enables IOMMU support in the gr2d and gr3d drivers and adds support for the zpos property on older Tegra generations. It also enables scaling filters and incorporates some rework to eliminate a private wrapper around struct drm_framebuffer. The remainder is mostly a random assortment of fixes and cleanups, as well as some preparatory work for destaging the userspace ABI, which is almost ready and is targetted for v4.19-rc1.
