2017-06-07drm/gma500/psb: Actually use VBT mode when it is foundPatrik Jakobsson1-7/+11
commit 82bc9a42cf854fdf63155759c0aa790bd1f361b0 upstream. With LVDS we were incorrectly picking the pre-programmed mode instead of the prefered mode provided by VBT. Make sure we pick the VBT mode if one is provided. It is likely that the mode read-out code is still wrong but this patch fixes the immediate problem on most machines.

2017-06-07drm/radeon: Unbreak HPD handling for r600+Lyude4-7/+7
commit 3d18e33735a02b1a90aecf14410bf3edbfd4d3dc upstream. We end up reading the interrupt register for HPD5, and then writing it to HPD6 which on systems without anything using HPD5 results in permanently disabling hotplug on one of the display outputs after the first time we acknowledge a hotplug interrupt from the GPU. This code is really bad. But for now, let's just fix this. I will hopefully have a large patch series to refactor all of this soon.

commit 04a68a35ce6d7b54749989f943993020f48fed62 upstream. Explicitly disable stolen memory when running as a guest in a virtual machine, since the memory is not mediated between clients and reserved entirely for the host.

2017-05-25drm/edid: Add 10 bpc quirk for LGD 764 panel in HP zBook 17 G2Mario Kleiner1-0/+8
commit e345da82bd6bdfa8492f80b3ce4370acfd868d95 upstream. The builtin eDP panel in the HP zBook 17 G2 supports 10 bpc, as advertised by the Laptops product specs and verified via injecting a fixed edid + photometer measurements, but edid reports unknown depth, so drivers fall back to 6 bpc. Add a quirk to get the full 10 bpc.

commit 1b0f84380b10ee97f7d2dd191294de9017e94d1d upstream. If the time to the next alarm is short enough, we could race with HW and end up with an ~4 second delay until it triggers.

commit 330bdf62fe6a6c5b99a647f7bf7157107c9348b3 upstream. The idea here was to avoid having to "manually" program the HW if there's a new earliest alarm.

commit e190ed1ea7458e446230de4113cc5d53b8dc4ec8 upstream. At dot clocks > approx. 250 Mhz, some of these calcs will overflow and cause miscalculation of latency watermarks, and for some overflows also divide-by-zero driver crash ("divide error: 0000 [#1] PREEMPT SMP" in "dce_v10_0_latency_watermark+0x12d/0x190"). This zero-divide happened, e.g., on AMD Tonga Pro under DCE-10, on a Displayport panel when trying to set a video mode of 2560x1440 at 165 Hz vrefresh with a dot clock of 635.540 Mhz.

Only call synchronize_rcu_expedited after unlocking struct_mutex to avoid deadlock because the workqueues depend on struct_mutex. >From original patch by Andrea: synchronize_rcu/synchronize_sched/synchronize_rcu_expedited() will hang until its own workqueues are run. The i915 gem workqueues will wait on the struct_mutex to be released. So we cannot wait for a quiescent state using those rcu primitives while holding the struct_mutex or it creates a circular lock dependency resulting in kernel hangs (which is reproducible but goes undetected by lockdep). kswapd0 D 0 700 2 0x00000000 Call Trace: ? __schedule+0x1a5/0x660 ? schedule+0x36/0x80 ? _synchronize_rcu_expedited.constprop.65+0x2ef/0x300 ? wake_up_bit+0x20/0x20 ? rcu_stall_kick_kthreads.part.54+0xc0/0xc0 ? rcu_exp_wait_wake+0x530/0x530 ? i915_gem_shrink+0x34b/0x4b0 ? i915_gem_shrinker_scan+0x7c/0x90 ? i915_gem_shrinker_scan+0x7c/0x90 ? shrink_slab.part.61.constprop.72+0x1c1/0x3a0 ? shrink_zone+0x154/0x160 ? kswapd+0x40a/0x720 ? kthread+0xf4/0x130 ? try_to_free_pages+0x450/0x450 ? kthread_create_on_node+0x40/0x40 ? ret_from_fork+0x23/0x30 plasmashell D 0 4657 4614 0x00000000 Call Trace: ? __schedule+0x1a5/0x660 ? schedule+0x36/0x80 ? schedule_preempt_disabled+0xe/0x10 ? __mutex_lock.isra.4+0x1c9/0x790 ? i915_gem_close_object+0x26/0xc0 ? i915_gem_close_object+0x26/0xc0 ? drm_gem_object_release_handle+0x48/0x90 ? drm_gem_handle_delete+0x50/0x80 ? drm_ioctl+0x1fa/0x420 ? drm_gem_handle_create+0x40/0x40 ? pipe_write+0x391/0x410 ? __vfs_write+0xc6/0x120 ? do_vfs_ioctl+0x8b/0x5d0 ?

2017-04-06drm/nouveau/mmu/nv4a: use nv04 mmu rather than the nv44 oneIlia Mirkin1-1/+1
The NV4A (aka NV44A) is an oddity in the family. It only comes in AGP and PCI varieties, rather than a core PCIE chip with a bridge for AGP/PCI as necessary. As a result, it appears that the MMU is also non-functional. For AGP cards, the vast majority of the NV4A lineup, this worked out since we force AGP cards to use the nv04 mmu. However for PCI variants, this did not work. Switching to the NV04 MMU makes it work like a charm. Thanks to mwk for the suggestion. This should be a no-op for NV4A AGP boards, as they were using it already.

2017-04-03drm/msm: Make sure to detach the MMU during GPU cleanupJordan Crouse2-13/+19
We should be detaching the MMU before destroying the address space. To do this cleanly, the detach has to happen in adreno_gpu_cleanup() because it needs access to structs in adreno_gpu.c. Plus it is better symmetry to have the attach and detach at the same code level. Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

2017-04-03drm/msm/mdp5: Update SSPP_MAX valueArchit Taneja1-1/+2
'SSPP_MAX + 1' is the max number of hwpipes that can be present on a MDP5 platform. Recently, 2 new cursor hwpipes were added, which caused overflows in arrays that used SSPP_MAX to represent the number of elements. Update the SSPP_MAX value to incorporate the extra hwpipes.

2017-04-03drm/msm/dsi: Fix bug in dsi_mgr_phy_enableArchit Taneja1-1/+1
A recent commit introduces a bug in dsi_mgr_phy_enable. In the non dual DSI mode, we reset the mdsi (master DSI) PHY. This isn't right since master and slave DSI exist only in dual DSI mode. For the normal mode of operation, we should simply reset the PHY of the DSI device (i.e. msm_dsi) corresponding to the current bridge. Usage of the wrong DSI pointer also resulted in a static checker warning. That too is resolved with this fix.

2017-03-31drm/i915: Use a dummy timeline name for a signaled fenceChris Wilson1-0/+11
Michał Winiarski pointed out that the debugging infrastructure (such as trace_dma_fence_release) likes to pretty print the timeline name, long after we have freed the timeline. Our timelines currently live as part of the GTT (due to the strict ordering we currently use through each) which belong to the context. We aim to free the context and release its hardware resources as soon as we able to (i.e. when the last fence/request using it has been signaled and retired). As the .get_timeline_name is purely a debug feature, rather than extending the lifetime of the context, or splitting it into many different release phases just to keep the name around, replace the timeline name with a constant after the fence has been signaled. This avoids the potential use-after-free.

2017-03-31drm/i915: Avoid lock dropping between reschedulingChris Wilson1-29/+24
Unlocking is dangerous. In this case we combine an early update to the out-of-queue request, because we know that it will be inserted into the correct FIFO priority-ordered slot when it becomes ready in the future. However, given sufficient enthusiasm, it may become ready as we are continuing to reschedule, and so may gazump the FIFO if we have since dropped its spinlock. The result is that it may be executed too early, before its dependencies. v2: Move all work into the second phase over the topological sort. This removes the shortcut on the out-of-rbtree request to ensure that we only adjust its priority after adjusting all of its dependencies.
