| * | | | | | | | | | | drm/i915: Hold mutex across i915_gem_releaseChris Wilson2013-12-04

Failing to do so has the potential to trigger an OOPS, later with a use-after-free.

| * | | | | | | | | | | drm/i915: Do not clobber config status after a forced restore of hw stateChris Wilson2013-12-03

During initialisation of the driver, it is imperative that we reset the config state. This correctly sets up the initial connector statuses and prepares the hardware for a thorough probing. However, during a lid event, we only want to undo the damage caused by the bios by resetting our last known mode. In this cirumstance, we do not want to clobber our desired state. In order to try and keep sanity between the config state and our own tracking, do the drm_mode_config_reset() first along the load/resume paths before reading out the hw state and apply any definite known corrections. v2: "As discussed on irc I don't think we should force the connector state to anything here: Imo connector->status should reflect what we believe to be the true output connection state, whereas connector->encoder reflects whether this connector is wired up to a pipe. And since we no longer reject modeset on disconnected connectors and never nuked the pipe if the connector gets disconnected there's no reason for that - such policy is userspace's job. This regression has been introduced in commit 2e9388923e83bc4e2726f170a984621f1d582e77 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Oct 11 20:08:24 2012 +0200 drm/i915/crt: explicitly set up HOTPLUG_BITS on resume" so sayeth Daniel.

| * | | | | | | | | | | drm/i915: Take modeset locks around intel_modeset_setup_hw_state()Ville Syrjälä2013-12-03

Actually the resume and lid_notify codepaths alreday hold the locks, but the init codepath doesn't, so fix that. Note: This slipped through since we only disable pipes if the plane/pipe linking doesn't match. Which is only relevant on older gen3 mobile machines, if the BIOS fails to set up our preferred linking.

Instead of a quick hack to fix this, we should defer until we have the real solution in place (allocating much less contiguous space). This wasn't found sooner because we didn't not have any systems supporting more than a 2GB GTT. Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

This made some sense as there was no pin on the CPU. With Haswell came the introduction of a CPU backlight pin, but the interface was still controlled by software with the same mechnism. Behind the scenes, hardware did all the dirty work for us. Broadwell no longer provides this for free. If we want to use the PCH backlight pin [1] then we have to set the override bit BLC_PWM_PCH_CTL1 and program BLC_PWM_PCH_CTL2 for the PWM values. This patch implements that. This patch is compile tested only, and given that I rarely if ever touch this code, careful review is welcome. [1] According to Art, we know of no devices that exist which use the CPU pin (and remember it has existed already on HSW). If such a device does exist, we'll have to handle it properly - this is left as TODO until then. v2: Drop the abstraction prep patch, as a bigger backlight overhaul is in the works, and do just the mimimal bdw enabling now.

Nothing really serious going on. For outstanding issues we still have the S4 fun due to the hsw S4 duct-tape pending (seems like I need to switch into angry maintainer mode on that one). And there's the mode merging revert to make my g33 work again still pending for drm core. For that one I don't have any more clue (and it looks like no one else has a good idea either). And apparently the locking WARN fix in here also needs to be replicated for boot, still confirming that one though. * tag 'drm-intel-fixes-2013-12-02' of git://people.freedesktop.org/~danvet/drm-intel: drm/i915: Pin pages whilst allocating for dma-buf vmap() drm/i915: MI_PREDICATE_RESULT_2 is HSW only drm/i915: Make the DERRMR SRM target global GTT drm/i915: use the correct force_wake function at the PC8 code drm/i915: Fix pipe CSC post offset calculation drm/i915: Simplify DP vs. eDP detection drm/i915: Check VBT for eDP ports on VLV drm/i915: use crtc_htotal in watermark calculations to match fastboot v2 drm/i915: Pin relocations for the duration of constructing the execbuffer drm/i915: take mode config lock around crtc disable at suspend drm/i915: Prefer setting PTE cache age to 3 drm/i915/ddi: set sink to power down mode on dp disable

However, the shrinker can and will reap any object that is unbound if the allocation for the array first fails. This includes the object which we are attempting to vmap(). The solution is to mark the object's pages as pinned whilst we try the allocation to prevent the use-after-free introduced by the potential shrinkage.

This is relatively simple as we can just keep the objects pinned for not just the relocation but until we are finished. One such example is the possibility of the context switch causing an eviction or hitting the shrinker in order to fit its object into the aperture.

The exynos_drm_crtc_dpms function waits for the completion of pended page flip events. However, preclose callback - this releases all unhandled page flip events - is called prior to the exynos_drm_crtc_dpms function call when drm is closed. So at this time, this will make the exynos_drm_crtc_dpms to wait infiniately for the completion of the page flip events. This patch releases the unhandled page flip events at postclose instead of preclose so that exynos_drm_crtc_dpms function can be waked up. Changelog v2: - fix a memory leak when drm is closed. . it has a memory leak when a requeste page flip is handled after drm_events_release() is called and before drm_fb_release() is called. At this time, a drm_pending_event will not be freed. So also this chage releases the drm_pending_event at postclose(). And it calls drm_vblank_put() for pair if there is any unhandled page flip event. Signed-off-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>

That has the disadvantage that when an encoder is detached from its CRTC, that field is set to NULL, leading to situations where it is impossible to access the DC registers required by the RGB output. However, the coupling between DC and RGB output is really fixed on Tegra. While they can be detached logically in DRM, the RGB output can rely on the DC's existence.

This allows subsequent code to check that the cast object is valid. Signed-off-by: Thierry Reding <treding@nvidia.com>
