2019-02-15drm: Use array_size() when creating leaseMatthew Wilcox
Passing an object_count of sufficient size will make object_count * 4 wrap around to be very small, then a later function will happily iterate off the end of the object_ids array. Using array_size() will saturate at SIZE_MAX, the kmalloc() will fail and we'll return an -ENOMEM to the norty userspace.

2019-02-12drm/i915: Block fbdev HPD processing during suspendLyude Paul
When resuming, we check whether or not any previously connected MST topologies are still present and if so, attempt to resume them. If this fails, we disable said MST topologies and fire off a hotplug event so that userspace knows to reprobe. However, sending a hotplug event involves calling drm_fb_helper_hotplug_event(), which in turn results in fbcon doing a connector reprobe in the caller's thread - something we can't do at the point in which i915 calls drm_dp_mst_topology_mgr_resume() since hotplugging hasn't been fully initialized yet. This currently causes some rather subtle but fatal issues. For example, on my T480s the laptop dock connected to it usually disappears during a suspend cycle, and comes back up a short while after the system has been resumed. This guarantees pretty much every suspend and resume cycle, drm_dp_mst_topology_mgr_set_mst(mgr, false); will be caused and in turn, a connector hotplug will occur. Now it's Rute Goldberg time: when the connector hotplug occurs, i915 reprobes /all/ of the connectors, including eDP. However, eDP probing requires that we power on the panel VDD which in turn, grabs a wakeref to the appropriate power domain on the GPU (on my T480s, this is the PORT_DDI_A_IO domain). This is where things start breaking, since this all happens before intel_power_domains_enable() is called we end up leaking the wakeref that was acquired and never releasing it later. Come next suspend/resume cycle, this causes us to fail to shut down the GPU properly, which causes it not to resume properly and die a horrible complicated death. (as a note: this only happens when there's both an eDP panel and MST topology connected which is removed mid-suspend. One or the other seems to always be OK). We could try to fix the VDD wakeref leak, but this doesn't seem like it's worth it at all since we aren't able to handle hotplug detection while resuming anyway. So, let's go with a more robust solution inspired by nouveau: block fbdev from handling hotplug events until we resume fbdev. This allows us to still send sysfs hotplug events to be handled later by user space while we're resuming, while also preventing us from actually processing any hotplug events we receive until it's safe. This fixes the wakeref leak observed on the T480s and as such, also fixes suspend/resume with MST topologies connected on this machine.

The old code never ever called virtio_gpu_resource_id_put().

On the D3 and E3 platforms, the LVDS internal PLL supplies the pixel clock to the DU. This works automatically for LVDS outputs as the LVDS encoder is enabled through the bridge API, enabling the internal PLL and clock output. However, when using the DU DPAD output with the LVDS outputs turned off, the LVDS PLL needs to be controlled manually. Add an API to do so, to be called by the DU driver. The drivers/gpu/drm/rcar-du/ directory has to be treated as obj-y unconditionally, as the LVDS driver could be built-in while the DU driver is compiled as a module.

2019-02-08drm: rcar-du: lvds: Don't fail probe if output is not connected on D3/E3Laurent Pinchart
On the D3 and E3 SoCs the LVDS encoder has an extended internal PLL and supplies a clock to the DU. That clock is used not only for the LVDS outputs but also for the DPAD output. The LVDS encoder thus needs to be available to the DU even when its output is disabled. Don't fail probe in that case on D3 and E3.

2019-02-08drm: rcar-du: Simplify encoder registrationLaurent Pinchart
Before the driver fully moved to drm_bridge and drm_panel, it was necessary to parse DT and locate encoder and connector nodes. The connector node is now unused and can be removed as a parameter to rcar_du_encoder_init(). As a consequence rcar_du_encoders_init_one() can be greatly simplified, removing most of the DT parsing.

2019-02-07drm/i915: Split color mgmt based on single vs. double buffered registersVille Syrjälä
Split the color management hooks along the single vs. double buffered registers line. Of the currently programmed registers GAMMA_MODE and the ilk+ pipe CSC are double buffered, the LUTS and CHV CGM block are single buffered. The double buffered register will be programmed during the normal pipe update with evasion, and also during pipe enable so that the settings will already be correct when the pipe starts up before the planes are enabled. The single buffered registers are currently programmed before the vblank evade. Which is totally wrong, but we'll correct that later. v2: Add some docs to explain the two vfuncs (Matt,Uma) Rebase Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190205160848.24662-6-ville.syrjala@linux.intel.com Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

2019-02-07drm/i915: Split the gamma/csc enable bits from the plane_ctl() functionVille Syrjälä
On g4x+ the pipe gamma enable bit for the primary plane affects the pipe bottom color as well. The same for the pipe csc enable bit on ilk+. Thus we must configure those bits correctly even when the primary plane is disabled. To make the feasible let's split those settings from the plane_ctl() function into a seprate funciton that we can call from the ->disable_plane() hook as well. For consistency we'll do that on all the plane types. While that has no real benefits at this time, it'll become useful when we start to control the pipe gamma/csc enable bits dynamically when we overhaul the color management code. On pre-g4x there doesn't appear to be any way to gamma correct the pipe bottom color, but sticking to the same pattern doesn't hurt. And it'll still help us to do crtc state readout correctly for the pipe gamma enable bit for the color management overhaul. An alternative apporach would be to still precompute these bits into plane_state->ctl, but that would require that we run through the plane check even when the plane isn't logically enabled on any crtc. Currently that condition causes us to short circuit the entire thing and not call ->check_plane(). There would also be some chicken and egg problems with ->check_plane() vs. crtc color state check that would requite splitting certain things into multiple steps. So all in all this seems like the easier route.
