2018-10-26dma-buf: Update reservation shared_count after adding the new fenceChris Wilson
We need to serialise the addition of a new fence into the shared list such that the fence is visible before we claim it is there. Otherwise a concurrent reader of the shared fence list will see an uninitialised fence slot before it is set. <4> [109.613162] general protection fault: 0000 [#1] PREEMPT SMP PTI <4> [109.613177] CPU: 1 PID: 1357 Comm: gem_busy Tainted: G U 4.19.0-rc8-CI-CI_DRM_5035+ #1 <4> [109.613189] Hardware name: Dell Inc.

2018-10-25drm/stm: Use drm_fbdev_generic_setup()Noralf Trønnes
The CMA helper is already using the drm_fb_helper_generic_probe part of the generic fbdev emulation. This patch makes full use of the generic fbdev emulation by using its drm_client callbacks. This means that drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are now handled by the emulation code. Additionally fbdev unregister happens automatically on drm_dev_unregister(). The drm_fbdev_generic_setup() call is put after drm_dev_register() in the driver. This is done to highlight the fact that fbdev emulation is an internal client that makes use of the driver, it is not part of the driver as such. If fbdev setup fails, an error is printed, but the driver succeeds probing. drm_fbdev_generic_setup() handles mode_config.num_connector being zero. In that case it retries fbdev setup on the next .output_poll_changed.

2018-10-25drm/virtio: document drm_dev_set_unique workaroundEmil Velikov
A while back we removed it, yet that lead to regressions. At some later point, I've attempted to remove it again without fully grasping the unique (pun intended) situation that virtio is in. Add a bulky comment to document why the call should stay as-is, for the next person who's around. As a Tl;Dr: virtio sits on top of struct virtio_device, which confuses dev_is_pci(), wrong info gets sent to userspace and X doesn't start.

There's no reason to track the atomic state three times. Unfortunately, this is currently what we're doing, and even worse is that there is only one actually correct state pointer: the one in mst_state->base.state. mgr->state never seems to be used, along with the one in mst_state->state.

2018-10-23vgaarb: Add support for 64-bit frame buffer addressAaron Ma
EFI GOP uses 64-bit frame buffer address when some BIOS disabled CSM support. vgaarb only stores lfb_base, this will lead boot framebuffer to wrong device. Add ext_lfb_base support to use 64-bit fb address.

2018-10-18drm: add syncobj timeline support v9Chunming Zhou
This patch is for VK_KHR_timeline_semaphore extension, semaphore is called syncobj in kernel side: This extension introduces a new type of syncobj that has an integer payload identifying a point in a timeline. Such timeline syncobjs support the following operations: * CPU query - A host operation that allows querying the payload of the timeline syncobj. * CPU wait - A host operation that allows a blocking wait for a timeline syncobj to reach a specified value. * Device wait - A device operation that allows waiting for a timeline syncobj to reach a specified value. * Device signal - A device operation that allows advancing the timeline syncobj to a specified value. v1: Since it's a timeline, that means the front time point(PT) always is signaled before the late PT. a. signal PT design: Signal PT fence N depends on PT[N-1] fence and signal opertion fence, when PT[N] fence is signaled, the timeline will increase to value of PT[N]. b. wait PT design: Wait PT fence is signaled by reaching timeline point value, when timeline is increasing, will compare wait PTs value with new timeline value, if PT value is lower than timeline value, then wait PT will be signaled, otherwise keep in list. syncobj wait operation can wait on any point of timeline, so need a RB tree to order them. And wait PT could ahead of signal PT, we need a sumission fence to perform that. v2: 1. remove unused DRM_SYNCOBJ_CREATE_TYPE_NORMAL. (Christian) 2. move unexposed denitions to .c file. (Daniel Vetter) 3. split up the change to drm_syncobj_find_fence() in a separate patch. (Christian) 4. split up the change to drm_syncobj_replace_fence() in a separate patch. 5. drop the submission_fence implementation and instead use wait_event() for that. (Christian) 6. WARN_ON(point != 0) for NORMAL type syncobj case. (Daniel Vetter) v3: 1. replace normal syncobj with timeline implemenation. (Vetter and Christian) a. normal syncobj signal op will create a signal PT to tail of signal pt list. b. normal syncobj wait op will create a wait pt with last signal point, and this wait PT is only signaled by related signal point PT. 2. many bug fix and clean up 3. stub fence moving is moved to other patch. v4： 1. fix RB tree loop with while(node=rb_first(...)). (Christian) 2. fix syncobj lifecycle. (Christian) 3. only enable_signaling when there is wait_pt. (Christian) 4. fix timeline path issues. 5. write a timeline test in libdrm v5: (Christian) 1. semaphore is called syncobj in kernel side. 2. don't need 'timeline' characters in some function name. 3. keep syncobj cb. v6: (Christian) 1. merge syncobj_timeline to syncobj structure. 2. simplify some check sentences. 3. some misc change. 4. fix CTS failed issue. v7: (Christian) 1. error handling when creating signal pt. 2. remove timeline naming in func. 3. export flags in find_fence. 4. allow reset timeline. v8: 1. use wait_event_interruptible without timeout 2. rename _TYPE_INDIVIDUAL to _TYPE_BINARY v9: 1. rename signal_pt->base to signal_pt->fence_array to avoid misleading 2. improve kerneldoc individual syncobj is tested by ./deqp-vk -n dEQP-VK*semaphore* timeline syncobj is tested by ./amdgpu_test -s 9 Signed-off-by: Chunming Zhou <david1.zhou@amd.com> Signed-off-by: Christian König <christian.koenig@amd.com> Cc: Christian Konig <christian.koenig@amd.com> Cc: Dave Airlie <airlied@redhat.com> Cc: Daniel Rakos <Daniel.Rakos@amd.com> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Bas Nieuwenhuizen <bas@basnieuwenhuizen.nl> Cc: Jason Ekstrand <jason@jlekstrand.net> Reviewed-by: Christian König <christian.koenig@amd.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/257258/

2018-10-17drm/i915/gen9+: Fix initial readout for Y tiled framebuffersImre Deak
If BIOS configured a Y tiled FB we failed to set up the backing object tiling accordingly, leading to a lack of GT fence installed and a garbled console. The problem was bisected to commit 011f22eb545a ("drm/i915: Do NOT skip the first 4k of stolen memory for pre-allocated buffers v2") but it just revealed a pre-existing issue.

For mmap-exhaustion, we deliberately put the system under a large amount of pressure to ensure that we are able to reap mmap-offsets from dead objects. If background activity does that reaping for us, that defeats the purpose of the test and in some cases will fail our sanity checks (because of the fake activity we use to prevent the idle worker).
