2022-04-06dma-buf/drivers: make reserving a shared slot mandatory v4Christian König
Audit all the users of dma_resv_add_excl_fence() and make sure they reserve a shared slot also when only trying to add an exclusive fence. This is the next step towards handling the exclusive fence like a shared one. v2: fix missed case in amdgpu v3: and two more radeon, rename function v4: add one more case to TTM, fix i915 after rebase Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20220406075132.3263-2-christian.koenig@amd.com

2017-09-08lib/interval_tree: fast overlap detectionDavidlohr Bueso
Allow interval trees to quickly check for overlaps to avoid unnecesary tree lookups in interval_tree_iter_first(). As of this patch, all interval tree flavors will require using a 'rb_root_cached' such that we can have the leftmost node easily available. While most users will make use of this feature, those with special functions (in addition to the generic insert, delete, search calls) will avoid using the cached option as they can do funky things with insertions -- for example, vma_interval_tree_insert_after().

There is no major nouveau changes in here, Ben was working on something big, and we agreed it was a bit late, there wasn't anything else he considered urgent to merge.

It also contains a set of register headers auto generated from AMD internal database. core: - atomic modesetting API completed, enabled by default now. - Add support for mode_id blob to atomic ioctl to complete interface. - bunch of Displayport MST fixes - lots of misc fixes. panel: - new simple panels - fix some long-standing build issues with bridge drivers radeon: - VCE1 support - add a GPU reset counter for userspace - lots of fixes. amdkfd: - H/W debugger support module - static user-mode queues - support killing all the waves when a process terminates - use standard DECLARE_BITMAP i915: - Add Broxton support - S3, rotation support for Skylake - RPS booting tuning - CPT modeset sequence fixes - ns2501 dither support - enable cmd parser on haswell - cdclk handling fixes - gen8 dynamic pte allocation - lots of atomic conversion work exynos: - Add atomic modesetting support - Add iommu support - Consolidate drm driver initialization - and MIC, DECON and MIPI-DSI support for exynos5433 omapdrm: - atomic modesetting support (fixes lots of things in rewrite) tegra: - DP aux transaction fixes - iommu support fix msm: - adreno a306 support - various dsi bits - various 64-bit fixes - NV12MT support rcar-du: - atomic and misc fixes sti: - fix HDMI timing complaince tilcdc: - use drm component API to access tda998x driver - fix module unloading qxl: - stability fixes" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (872 commits) drm/nouveau: Pause between setting gpu to D3hot and cutting the power drm/dp/mst: close deadlock in connector destruction. drm: Always enable atomic API drm/vgem: Set unique to "vgem" of: fix a build error to of_graph_get_endpoint_by_regs function drm/dp/mst: take lock around looking up the branch device on hpd irq drm/dp/mst: make sure mst_primary mstb is valid in work function of: add EXPORT_SYMBOL for of_graph_get_endpoint_by_regs ARM: dts: rename the clock of MIPI DSI 'pll_clk' to 'sclk_mipi' drm/atomic: Don't set crtc_state->enable manually drm/exynos: dsi: do not set TE GPIO direction by input drm/exynos: dsi: add support for MIC driver as a bridge drm/exynos: dsi: add support for Exynos5433 drm/exynos: dsi: make use of array for clock access drm/exynos: dsi: make use of driver data for static values drm/exynos: dsi: add macros for register access drm/exynos: dsi: rename pll_clk to sclk_clk drm/exynos: mic: add MIC driver of: add helper for getting endpoint node of specific identifiers drm/exynos: add Exynos5433 decon driver ...
