2020-03-26mm/hmm: check the device private page owner in hmm_range_fault()Christoph Hellwig
hmm_range_fault() will succeed for any kind of device private memory, even if it doesn't belong to the calling entity. While nouveau has some crude checks for that, they are broken because they assume nouveau is the only user of device private memory. Fix this by passing in an expected pgmap owner in the hmm_range_fault structure. If a device_private page is found and doesn't match the owner then it is treated as an non-present and non-faultable page. This prevents a bug in amdgpu, where it doesn't know how to handle device_private pages, but hmm_range_fault would return them anyhow.

2020-03-26mm: simplify device private page handling in hmm_range_faultChristoph Hellwig
Remove the HMM_PFN_DEVICE_PRIVATE flag, no driver has ever set this flag on input, and the only place that uses it on output can be trivially changed to use is_device_private_page(). This removes the ability to request that device_private pages are faulted back into system memory.

2020-03-26drm/i915/gt: Stage the transfer of the virtual breadcrumbChris Wilson
We move the virtual breadcrumb from one physical engine to the next, if the next virtual request is scheduled on a new physical engine. Since the virtual context can only be in one signal queue, we need it to track the current physical engine for the new breadcrumbs. However, to move the list we need both breadcrumb locks -- and since we cannot take both at the same time (unless we are careful and always ensure consistent ordering) stage the movement of the signaler via the current virtual request.

2020-03-26drm/vboxvideo: Add missing remove_conflicting_pci_framebuffers call, v2Hans de Goede
The vboxvideo driver is missing a call to remove conflicting framebuffers. Surprisingly, when using legacy BIOS booting this does not really cause any issues. But when using UEFI to boot the VM then plymouth will draw on both the efifb /dev/fb0 and /dev/drm/card0 (which has registered /dev/fb1 as fbdev emulation). VirtualBox will actual display the output of both devices (I guess it is showing whatever was drawn last), this causes weird artifacts because of pitch issues in the efifb when the VM window is not sized at 1024x768 (the window will resize to its last size once the vboxvideo driver loads, changing the pitch). Adding the missing drm_fb_helper_remove_conflicting_pci_framebuffers() call fixes this.

2020-03-25drm/amd/display: Fix pageflip event race condition for DCN.Mario Kleiner
Commit '16f17eda8bad ("drm/amd/display: Send vblank and user events at vsartup for DCN")' introduces a new way of pageflip completion handling for DCN, and some trouble. The current implementation introduces a race condition, which can cause pageflip completion events to be sent out one vblank too early, thereby confusing userspace and causing flicker: prepare_flip_isr(): 1. Pageflip programming takes the ddev->event_lock. 2. Sets acrtc->pflip_status == AMDGPU_FLIP_SUBMITTED 3. Releases ddev->event_lock. --> Deadline for surface address regs double-buffering passes on target pipe. 4. dc_commit_updates_for_stream() MMIO programs the new pageflip into hw, but too late for current vblank. => pflip_status == AMDGPU_FLIP_SUBMITTED, but flip won't complete in current vblank due to missing the double-buffering deadline by a tiny bit. 5. VSTARTUP trigger point in vblank is reached, VSTARTUP irq fires, dm_dcn_crtc_high_irq() gets called. 6. Detects pflip_status == AMDGPU_FLIP_SUBMITTED and assumes the pageflip has been completed/will complete in this vblank and sends out pageflip completion event to userspace and resets pflip_status = AMDGPU_FLIP_NONE. => Flip completion event sent out one vblank too early. This behaviour has been observed during my testing with measurement hardware a couple of time. The commit message says that the extra flip event code was added to dm_dcn_crtc_high_irq() to prevent missing to send out pageflip events in case the pflip irq doesn't fire, because the "DCH HUBP" component is clock gated and doesn't fire pflip irqs in that state. Also that this clock gating may happen if no planes are active. This suggests that the problem addressed by that commit can't happen if planes are active. The proposed solution is therefore to only execute the extra pflip completion code iff the count of active planes is zero and otherwise leave pflip completion handling to the pflip irq handler, for a more race-free experience. Note that i don't know if this fixes the problem the original commit tried to address, as i don't know what the test scenario was. It does fix the observed too early pageflip events though and points out the problem introduced.

2020-03-24drm/vmwgfx: Introduce a huge page aligning TTM range managerThomas Hellstrom (VMware)
Using huge page-table entries requires that the physical address of the start of a buffer object is huge page size aligned. Make a special version of the TTM range manager that accomplishes this, but falls back to a smaller page size alignment (PUD->PMD, PMD->NORMAL) to avoid eviction. If other drivers want to use it in the future, it can be made a TTM generic helper. Note that drivers can force eviction for a certain alignment by assigning the TTM GPU alignment correspondingly.

2020-03-24drm/ttm, drm/vmwgfx: Support huge TTM pagefaultsThomas Hellstrom (VMware)
Support huge (PMD-size and PUD-size) page-table entries by providing a huge_fault() callback. We still support private mappings and write-notify by splitting the huge page-table entries on write-access. Note that for huge page-faults to occur, either the kernel needs to be compiled with trans-huge-pages always enabled, or the kernel needs to be compiled with trans-huge-pages enabled using madvise, and the user-space app needs to call madvise() to enable trans-huge pages on a per-mapping basis. Furthermore huge page-faults will not succeed unless buffer objects and user-space addresses are aligned on huge page size boundaries.
