2021-10-13drm/amdkfd: unregistered svm range not overlap with TTM rangePhilip Yang3-7/+94
When creating unregistered new svm range to recover retry fault, avoid new svm range to overlap with ranges or userptr ranges managed by TTM, otherwise svm migration will trigger TTM or userptr eviction, to evict user queues unexpectedly. Change helper amdgpu_ttm_tt_affect_userptr to return userptr which is inside the range. Add helper svm_range_check_vm_userptr to scan all userptr of the vm, and return overlap userptr bo start, last.

This was previously left disabled by default because of issues with compositors that do not pageflip and scan out directly to the frontbuffer.

This may introduce bugs or new cases not tested by users so this is only currently targeting newer DCN.

2021-10-13drm/locking: add backtrace for locking contended locks without backoffJani Nikula2-2/+62
If drm_modeset_lock() returns -EDEADLK, the caller is supposed to drop all currently held locks using drm_modeset_backoff(). Failing to do so will result in warnings and backtraces on the paths trying to lock a contended lock. Add support for optionally printing the backtrace on the path that hit the deadlock and didn't gracefully handle the situation. For example, the patch [1] inadvertently dropped the return value check and error return on replacing calc_watermark_data() with intel_compute_global_watermarks(). The backtraces on the subsequent locking paths hitting WARN_ON(ctx->contended) were unhelpful, but adding the backtrace to the deadlock path produced this helpful printout: <7> [98.002465] drm_modeset_lock attempting to lock a contended lock without backoff: drm_modeset_lock+0x107/0x130 drm_atomic_get_plane_state+0x76/0x150 skl_compute_wm+0x251d/0x2b20 [i915] intel_atomic_check+0x1942/0x29e0 [i915] drm_atomic_check_only+0x554/0x910 drm_atomic_nonblocking_commit+0xe/0x50 drm_mode_atomic_ioctl+0x8c2/0xab0 drm_ioctl_kernel+0xac/0x140 Add new CONFIG_DRM_DEBUG_MODESET_LOCK to enable modeset lock debugging with stack depot and trace.

2021-10-13drm: rcar-du: Don't create encoder for unconnected LVDS outputsLaurent Pinchart3-4/+28
On R-Car D3 and E3, the LVDS encoders provide the pixel clock to the DU, even when LVDS outputs are not used. For this reason, the rcar-lvds driver probes successfully on those platforms even if no further bridge or panel is connected to the LVDS output, in order to provide the rcar_lvds_clk_enable() and rcar_lvds_clk_disable() functions to the DU driver. If an LVDS output isn't connected, trying to create a DRM connector for the output will fail. Fix this by skipping connector creation in that case, and also skip creation of the DRM encoder as there's no point in an encoder without a connector.

2021-10-12drm/i915/dg2: update link training for 128b/132bJani Nikula2-36/+133
The 128b/132b channel coding link training uses more straightforward TX FFE preset values. Reuse voltage tries and max vswing for retry logic. The delays for 128b/132b are still all wrong, but this is regardless a step forward. v2: Fix UHBR rate checks, use intel_dp_is_uhbr() helper v3: - Rebase - Modify intel_dp_adjust_request_changed() and intel_dp_link_max_vswing_reached() to take 128b/132b into account. (Ville) v4: - Train request printing for TX FFE (Ville) - Log 8b/10b vs. 128b/132b (Ville) - Add helper for per-lane max vswing / tx ffe (Ville) - Name functions with tx_ffe/vswing instead of 128b132b/8b10b Cc: Ville Syrjälä <[email protected]> Reviewed-by: Ville Syrjälä <[email protected]> Signed-off-by: Jani Nikula <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2021-10-11drm/msm/dsi: dsi_phy_14nm: Take ready-bit into account in poll_for_readyMarijn Suijten1-15/+15
The downstream driver models this PLL lock check as an if-elseif-else. The only way to reach the else case where pll_locked=true [1] is by succeeding both readl_poll_timeout_atomic calls (which return zero on success) in the if _and_ elseif condition. Hence both the "lock" and "ready" bit need to be tested in the SM_READY_STATUS register before considering the PLL locked and ready to go. Tested on the Sony Xperia XA2 Ultra (nile-discovery, sdm630).

2021-10-11drm/msm/dsi/phy: fix clock names in 28nm_8960 phyDmitry Baryshkov1-2/+2
The commit 9f91f22aafcd ("drm/msm/dsi: remove duplicate fields from dsi_pll_Nnm instances") mistakenly changed registered clock names. While the platform is in progress of migration to using clock properties in the dts rather than the global clock names, we should provide backwards compatibility. Thus restore registerd global clock names.
