2018-12-08drm/amd/dm: Don't forget to attach MST encodersLyude Paul1-0/+2
commit c9e0ab86b2e03154bb898cd2f851827783224727 upstream. The change fixed huge delay in SST daisy chain and S3 soft hang observed in 4.19 kernel rebase. Regression point in drm: drm/fb-helper: Eliminate the .best_encoder() usage The aux sequence is altered due to the failure in drm_connector_for_each_possible_encoder(). The failure is caused by missing attached encoder in the process of adding MST connector.   drm_dp_send_enum_path_resources() aux transaction is pushed after mode probe, which causes conflict to drm_dp_mst_i2c_xfer(), leading to the transaction timeout.

2018-11-27drm/amd/amdgpu/dm: Fix dm_dp_create_fake_mst_encoder()Lyude Paul1-5/+0
[ Upstream commit 63237f8748bdf46dccf79ef8f98f05e9fe799162 ] [why] Removing connector reusage from DM to match the rest of the tree ended up revealing an issue that was surprisingly subtle. The original amdgpu code for DC that was submitted appears to have left a chunk in dm_dp_create_fake_mst_encoder() that tries to find a "master encoder", the likes of which isn't actually used or stored anywhere. It does so at the wrong time as well by trying to access parts of the drm_connector from the encoder init before it's actually been initialized.

2018-11-21drm/amdgpu: Suppress keypresses from ACPI_VIDEO eventsLyude Paul1-5/+12
commit 582f58de36834096a91cc1de2540c2f7269f850d upstream. Currently we return NOTIFY_DONE for any event which we don't think is ours. However, many laptops will send more then just an ATIF event and will also send an ACPI_VIDEO_NOTIFY_PROBE event as well. Since we don't check for this, we return NOTIFY_DONE which causes a keypress for the ACPI event to be propogated to userspace. This is the equivalent of someone pressing the display key on a laptop every time there's a hotplug event. So, check for ACPI_VIDEO_NOTIFY_PROBE events and suppress keypresses from them.

2018-10-04drm/amd/display: Signal hw_done() after waiting for flip_done()Shirish S1-2/+8
In amdgpu_dm_commit_tail(), wait until flip_done() is signaled before we signal hw_done(). [Why] This is to temporarily address a paging error that occurs when a nonblocking commit contends with another commit, particularly in a mirrored display configuration where at least 2 CRTCs are updated. The error occurs in drm_atomic_helper_wait_for_flip_done(), when we attempt to access the contents of new_crtc_state->commit. Here's the sequence for a mirrored 2 display setup (irrelevant steps left out for clarity): **THREAD 1** | **THREAD 2** | Initialize atomic state for flip | | Queue worker | ... | Do work for flip | | Signal hw_done() on CRTC 1 | Signal hw_done() on CRTC 2 | | Wait for flip_done() on CRTC 1 <---- **PREEMPTED BY THREAD 1** Initialize atomic state for cursor | update (1) | | Do cursor update work on both CRTCs | | Clear atomic state (2) | **DONE** | ... | | Wait for flip_done() on CRTC 2 | *ERROR* | The issue starts with (1). When the atomic state is initialized, the current CRTC states are duplicated to be the new_crtc_states, and referenced to be the old_crtc_states. (The new_crtc_states are to be filled with update data.) Some things to note: * Due to the mirrored configuration, the cursor updates on both CRTCs. * At this point, the pflip IRQ has already been handled, and flip_done signaled on all CRTCs. The cursor commit can therefore continue. * The old_crtc_states used by the cursor update are the **same states** as the new_crtc_states used by the flip worker. At (2), the old_crtc_state is freed (*), and the cursor commit completes. We then context switch back to the flip worker, where we attempt to access the new_crtc_state->commit object. This is problematic, as this state has already been freed. (*) Technically, 'state->crtcs[i].state' is freed, which was made to reference old_crtc_state in drm_atomic_helper_swap_state() [How] By moving hw_done() after wait_for_flip_done(), we're guaranteed that the new_crtc_state (from the flip worker's perspective) still exists. This is because any other commit will be blocked, waiting for the hw_done() signal. Note that both the i915 and imx drivers have this sequence flipped already, masking this problem.

2018-09-20drm/amdkfd: Change the control stack MTYPE from UC to NC on GFX9Yong Zhao5-5/+10
CWSR fails on Raven if the control stack is MTYPE_UC, which is used for regular GART mappings. As a workaround we map it using MTYPE_NC. The MEC firmware expects the control stack at one page offset from the start of the MQD so it is part of the MQD allocation on GFXv9. AMDGPU added a memory allocation flag just for this purpose.

Even the bo was evicted, it won't set the bo_base->moved. 3.drm_gem_open_ioctl->amdgpu_vm_bo_base_init, here only called list_move_tail(&base->vm_status, &vm->evicted), but not set the bo_base->moved. 4.amdgpu_vm_bo_map->amdgpu_vm_bo_insert_map, as the bo_base->moved is not set true, the function amdgpu_vm_bo_insert_map will call list_move(&bo_va->base.vm_status, &vm->moved) 5.amdgpu_cs_ioctl won't validate the swapout bo, as it is only in the moved list, not in the evict list.

2018-08-22mm, oom: distinguish blockable mode for mmu notifiersMichal Hocko1-8/+35
There are several blockable mmu notifiers which might sleep in mmu_notifier_invalidate_range_start and that is a problem for the oom_reaper because it needs to guarantee a forward progress so it cannot depend on any sleepable locks. Currently we simply back off and mark an oom victim with blockable mmu notifiers as done after a short sleep. That can result in selecting a new oom victim prematurely because the previous one still hasn't torn its memory down yet. We can do much better though. Even if mmu notifiers use sleepable locks there is no reason to automatically assume those locks are held. Moreover majority of notifiers only care about a portion of the address space and there is absolutely zero reason to fail when we are unmapping an unrelated range. Many notifiers do really block and wait for HW which is harder to handle and we have to bail out though. This patch handles the low hanging fruit. __mmu_notifier_invalidate_range_start gets a blockable flag and callbacks are not allowed to sleep if the flag is set to false. This is achieved by using trylock instead of the sleepable lock for most callbacks and continue as long as we do not block down the call chain. I think we can improve that even further because there is a common pattern to do a range lookup first and then do something about that. The first part can be done without a sleeping lock in most cases AFAICS. The oom_reaper end then simply retries if there is at least one notifier which couldn't make any progress in !blockable mode. A retry loop is already implemented to wait for the mmap_sem and this is basically the same thing. The simplest way for driver developers to test this code path is to wrap userspace code which uses these notifiers into a memcg and set the hard limit to hit the oom. This can be done e.g. after the test faults in all the mmu notifier managed memory and set the hard limit to something really small. Then we are looking for a proper process tear down.
