execlist_update_context() will try to update PDPs in a context before a ELSP submission only for full PPGTT mode, while PDPs was populated during context initialization. Now the latter code path is removed. Let execlist_update_context() also cover !FULL_PPGTT mode.

To be consistent with the recent change to enable hotplug detection early on GEN9 platforms do the same on all non-GMCH platforms starting from GEN5. On GMCH platforms enabling detection without interrupts isn't trivial, since AUX and HPD have a shared interrupt line. It could be done there too by using a SW interrupt mask, but I punt on that for now.

This effectively reverts commit 489375c8 Author: Imre Deak <imre.deak@intel.com> Date: Mon Oct 24 19:33:31 2016 +0300 drm/i915/lspcon: Add workaround for resuming in PCON mode The workaround was added without considering that HPD is low during the failed AUX transfers the WA fixed. Since the previous patch we wait for HPD to get asserted. My tests also show that this happens _after_ the DPCD reads start to return correct values. This suggests that we don't need this WA any more, let's try to remove it to reduce the clutter.

During system resume time initialization the HPD level on LSPCON ports can stay low for an extended amount of time, leading to failed AUX transfers and LSPCON initialization.

For LSPCON resume time initialization we need to sample the corresponding pin's HPD level, but this is only available when HPD detection is enabled. Currently we enable detection only when enabling HPD interrupts which is too late, so bring the enabling of detection earlier. This is needed by the next patch.

The drm_mm range manager (within i915_address_space) uses a special drm_mm_node that excludes the unavailable range (beyond the end of the drm_mm). However, we play games with the global GTT to use the head_node to exclude the tail page but tell ourselves that the whole range is available. This causes an issue when we try to evict using the full range of the global GTT which is wider than the drm_mm, resulting in complete confusion and catastrophe. One way to resolve this would be to use a reserved node to exclude the guard page, or we can treat the drm_mm's head_node as our guard page and assign it the appropriate colour. Signed-off-by:

If we have any residual freed atomic state from earlier commits, flush the freed list after performing the current modeset. This prevents the freed list from ever-growing if userspace manages to starve the kernel threads (i.e. we are never able to run our free state worker and eventually the system may even oom).

Commit 920cf419 ("drm/i915: Introduce an internal allocator for disposable private objects") introduced a regression for the kernel running as Xen dom0: when switching to graphics mode a GPU HANG occurred. Reason seems to be a missing adaption similar to that done in commit 7453c549 ("swiotlb: Export swiotlb_max_segment to users") to i915_gem_object_get_pages_internal(). So limit the maximum page order to be used according to the maximum swiotlb segment size instead to the complete swiotlb size.

If the crtc was brought up with audio before the driver loads, then crtc_disable will remove a refcount to audio that doesn't exist before. Fortunately we already set power domains on readout, so we can just add the power domain handling to get_crtc_power_domains, which will update the power domains correctly in all cases. This was found when testing module reload on CI with the crtc enabled, which resulted in the following warn after module reload + modeset: [ 24.197041] ------------[ cut here ]------------ [ 24.197075] WARNING: CPU: 0 PID: 99 at drivers/gpu/drm/i915/intel_runtime_pm.c:1790 intel_display_power_put+0x134/0x140 [i915] [ 24.197076] Use count on domain AUDIO is already zero [ 24.197098] CPU: 0 PID: 99 Comm: kworker/u8:2 Not tainted 4.9.0-CI-Trybot_393+ #1 [ 24.197099] Hardware name: /NUC6i5SYB, BIOS SYSKLi35.86A.0042.2016.0409.1246 04/09/2016 [ 24.197102] Workqueue: events_unbound async_run_entry_fn [ 24.197105] ffffc900003c7688 ffffffff81435b35 ffffc900003c76d8 0000000000000000 [ 24.197107] ffffc900003c76c8 ffffffff8107e4d6 000006fe5dc36f28 ffff88025dc30054 [ 24.197109] ffff88025dc36f28 ffff88025dc30000 ffff88025dc30000 0000000000000015 [ 24.197110] Call Trace: [ 24.197113] [<ffffffff81435b35>] dump_stack+0x67/0x92 [ 24.197116] [<ffffffff8107e4d6>] __warn+0xc6/0xe0 [ 24.197118] [<ffffffff8107e53a>] warn_slowpath_fmt+0x4a/0x50 [ 24.197149] [<ffffffffa039b4b4>] intel_display_power_put+0x134/0x140 [i915] [ 24.197187] [<ffffffffa04217dd>] intel_disable_ddi+0x4d/0x80 [i915] [ 24.197223] [<ffffffffa03f388f>] intel_encoders_disable.isra.74+0x7f/0x90 [i915] [ 24.197257] [<ffffffffa03f6c05>] haswell_crtc_disable+0x55/0x170 [i915] [ 24.197292] [<ffffffffa03fec88>] intel_atomic_commit_tail+0x108/0xfd0 [i915] [ 24.197295] [<ffffffff810d47c6>] ? __lock_is_held+0x66/0x90 [ 24.197330] [<ffffffffa03fff79>] intel_atomic_commit+0x429/0x560 [i915] [ 24.197332] [<ffffffff81570186>] ?drm_atomic_add_affected_connectors+0x56/0xf0 [ 24.197334] [<ffffffff8156f726>] drm_atomic_commit+0x46/0x50 [ 24.197336] [<ffffffff81553f87>] restore_fbdev_mode+0x147/0x270 [ 24.197337] [<ffffffff81555bee>] drm_fb_helper_restore_fbdev_mode_unlocked+0x2e/0x70 [ 24.197339] [<ffffffff81555aa8>] drm_fb_helper_set_par+0x28/0x50 [ 24.197374] [<ffffffffa041c7d3>] intel_fbdev_set_par+0x13/0x70 [i915] [ 24.197376] [<ffffffff8149e07a>] fbcon_init+0x57a/0x600 [ 24.197379] [<ffffffff81514b71>] visual_init+0xd1/0x130 [ 24.197381] [<ffffffff8151603c>] do_bind_con_driver+0x1bc/0x3a0 [ 24.197384] [<ffffffff81516521>] do_take_over_console+0x111/0x180 [ 24.197386] [<ffffffff8149e152>] do_fbcon_takeover+0x52/0xb0 [ 24.197387] [<ffffffff814a12c3>] fbcon_event_notify+0x723/0x850 [ 24.197390] [<ffffffff810a4830>] ?__blocking_notifier_call_chain+0x30/0x70 [ 24.197392] [<ffffffff810a44a4>] notifier_call_chain+0x34/0xa0 [ 24.197394] [<ffffffff810a4848>] __blocking_notifier_call_chain+0x48/0x70 [ 24.197397] [<ffffffff810a4881>] blocking_notifier_call_chain+0x11/0x20 [ 24.197398] [<ffffffff814a4556>] fb_notifier_call_chain+0x16/0x20 [ 24.197400] [<ffffffff814a678c>] register_framebuffer+0x24c/0x330 [ 24.197402] [<ffffffff815558d9>] drm_fb_helper_initial_config+0x219/0x3c0 [ 24.197436] [<ffffffffa041d373>] intel_fbdev_initial_config+0x13/0x30 [i915] [ 24.197438] [<ffffffff810a5d44>] async_run_entry_fn+0x34/0x140 [ 24.197440] [<ffffffff8109c26c>] process_one_work+0x1ec/0x6b0 [ 24.197442] [<ffffffff8109c1e6>] ? process_one_work+0x166/0x6b0 [ 24.197445] [<ffffffff8109c779>] worker_thread+0x49/0x490 [ 24.197447] [<ffffffff8109c730>] ? process_one_work+0x6b0/0x6b0 [ 24.197448] [<ffffffff810a2a9b>] kthread+0xeb/0x110 [ 24.197451] [<ffffffff810a29b0>] ? kthread_park+0x60/0x60 [ 24.197453] [<ffffffff818241a7>] ret_from_fork+0x27/0x40 [ 24.197476] ---[ end trace bda64b683b8e8162 ]--- Signed-off-by:

Merge tag 'zxdrm-4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into drm-next ZTE DRM driver updates for 4.11: - Add missing selection of VIDEOMODE_HELPERS in Kconfig, since ZTE DRM driver uses drm_display_mode_to_videomode(). - Enable HDMI audio support through SPDIF interface based on generic hdmi-audio-codec driver. - Enable VOU VL (Video Layer) to support overlay plane with scaling function. - Refine zx_vou driver a bit and then add TV Encoder output device support.

Hope I'm not too late before the cutoff for the v4.11 with these patches. Mostly an asorted set of fixes that we have discovered while playing with the code and preparing for the next set of features. * 'for-upstream/mali-dp' of git://linux-arm.org/linux-ld: drm: mali-dp: fix stride setting for multi-plane formats drm: mali-dp: Add plane offset to the plane's physical start address register drm: mali-dp: Check for sufficient address space drm: mali-dp: Check hw version matches device-tree drm: mali-dp: Rename malidp_input_format to malidp_pixel_format drm: mali-dp: fix Lx_CONTROL register fields clobber drm: mali-dp: Fix transposed horizontal/vertical flip drm: mali-dp: Fix destination size handling when rotating drm: mali-dp: Don't force source size == crtc size drm: mali-dp: Check more use cases in the plane's ->atomic_check() drm: malidp: Remove event_list member from struct malidp_drm drm/arm/malidp: Fix possible dereference of NULL

Just do a quick check that the stolen memory address range doesn't overflow our chosen integer type. v2: Add add_overflows() to utils with the promise that gcc7 can do this better than C and then maybe it will have a proper definition in core. Signed-off-by:

The conversion of stolen to use phys_addr_t (from essentially u32) sparked an interesting discussion. We treat stolen memory as only accessible from the GPU (the DMA device) - an attempt to use it from the CPU will generate a MCE on gen6 onwards, although it is in theory a physical address that can be dereferenced from the CPU as demonstrated by earlier generations. As such, using phys_addr_t has the wrong connotations and as we pass the address into the DMA device via dma_addr_t (through the scatterlists used to program the GTT entries), we should treat it as dma_addr_t throughout.
