2016-07-29drm/radeon: Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar1-1/+1
alloc_workqueue replaces deprecated create_singlethread_workqueue(). Each hardware CRTC has a single flip work queue. When a radeon_flip_work_func item is queued, it needs to be executed ASAP because even a slight delay may cause the flip to be delayed by one refresh cycle. Hence, a dedicated workqueue with WQ_HIGHPRI set, has been used here since a delay can cause the outcome to miss the refresh cycle. Since there are only a fixed number of work items, explicit concurrency limit is unnecessary here.

2016-07-07drm/radeon: Poll for both connect/disconnect on analog connectorsLyude1-6/+9
DRM_CONNECTOR_POLL_CONNECT only enables polling for connections, not disconnections. Because of this, we end up losing hotplug polling for analog connectors once they get connected. Easy way to reproduce: - Grab a machine with a radeon GPU and a VGA port - Plug a monitor into the VGA port, wait for it to update the connector from disconnected to connected - Disconnect the monitor on VGA, a hotplug event is never sent for the removal of the connector. Originally, only using DRM_CONNECTOR_POLL_CONNECT might have been a good idea since doing VGA polling can sometimes result in having to mess with the DAC voltages to figure out whether or not there's actually something there since VGA doesn't have HPD. Doing this would have the potential of showing visible artifacts on the screen every time we ran a poll while a VGA display was connected. Luckily, radeon_vga_detect() only resorts to this sort of polling if the poll is forced, and DRM's polling helper doesn't force it's polls. Additionally, this removes some assignments to connector->polled that weren't actually doing anything.

2016-06-24drm/radeon: Forbid runtime pm on driver unloadLukas Wunner1-0/+1
The PCI core calls pm_runtime_forbid() on device probe in pci_pm_init(), making this the default state when radeon is loaded. radeon_driver_load_kms() therefore calls pm_runtime_allow(), but there's no pm_runtime_forbid() in radeon_driver_unload_kms() to balance it. Add it so that we leave the device in the same state that we found it. This isn't a bug, it's just good housekeeping. When radeon is first loaded with runpm=1, then unloaded and loaded again with runpm=0, pm_runtime_forbid() will be called from radeon_pmops_runtime_idle() or radeon_pmops_runtime_suspend(), so the behaviour is correct. If there ever is a third party driver for AMD cards, this commit avoids that it has to clean up behind radeon.

2016-06-24drm/radeon: Don't leak runtime pm ref on driver unloadLukas Wunner1-1/+3
radeon_driver_load_kms() calls pm_runtime_put_autosuspend() if radeon_is_px(dev), but radeon_driver_unload_kms() calls pm_runtime_get_sync() unconditionally. We therefore leak a runtime pm ref whenever radeon is unloaded on a non-PX machine or if runpm=0. The GPU will subsequently never runtime suspend after loading radeon again. Fix by taking the runtime pm ref under the same condition that it was released on driver load.

Fence contexts are created on the fly (for example) by the GPU scheduler used in the amdgpu driver as a result of an userspace request. Because of this userspace could in theory force a wrap around of the 32bit context number if it doesn't behave well. Avoid this by increasing the context number to 64bits. This way even when userspace manages to allocate a billion contexts per second it takes more than 500 years for the context number to wrap around. v2: fix printf formats as well.

I'm starting a bit earlier this time around because there's a few invasive patch series to land (nonblocking atomic prep work, fence prep work, rst/sphinx kerneldoc finally happening) and I need a baseline with all the branches merged. * tag 'topic/drm-misc-2016-06-01' of git://anongit.freedesktop.org/drm-intel: (21 commits) drm/vc4: Use lockless gem BO free callback drm/vc4: Use drm_gem_object_unreference_unlocked drm: Initialize a linear gamma table by default drm/vgem: Use lockless gem BO free callback drm/qxl: Don't set a gamma table size drm/msm: Nuke dummy gamma_set/get functions drm/cirrus: Drop redundnant gamma size check drm/fb-helper: Remove dead code in setcolreg drm/mediatek: Use lockless gem BO free callback drm/hisilicon: Use lockless gem BO free callback drm/hlcd: Use lockless gem BO free callback vga_switcheroo: Support deferred probing of audio clients vga_switcheroo: Add helper for deferred probing virtio-gpu: fix output lookup drm/doc: Unify KMS Locking docs drm/atomic-helper: Do not call ->mode_fixup for CRTC which will be disabled Fix annoyingly awkward typo in drm_edid_load.c drm/doc: Drop vblank_disable_allow wording drm: use seqlock for vblank time/count drm/mm: avoid possible null pointer dereference ...
2016-05-31vga_switcheroo: Add helper for deferred probingLukas Wunner1-9/+1
So far we've got one condition when DRM drivers need to defer probing on a dual GPU system and it's coded separately into each of the relevant drivers. As suggested by Daniel Vetter, deduplicate that code in the drivers and move it to a new vga_switcheroo helper. This yields better encapsulation of concepts and lets us add further checks in a central place. (The existing check pertains to pre-retina MacBook Pros and an additional check is expected to be needed for retinas.) One might be tempted to check deferred probing conditions in vga_switcheroo_register_client(), but this is usually called fairly late during driver load. The GPU is fully brought up and ready for switching at that point. On boot the ->probe hook is potentially called dozens of times until it finally succeeds, and each time we'd repeat bringup and teardown of the GPU, lengthening boot time considerably and cluttering logfiles. A separate helper is therefore needed which can be called right at the beginning of the ->probe hook. Note that amdgpu currently does not call this helper as the AMD GPUs built into MacBook Pros are only supported by radeon so far. v2: This helper could eventually be used by audio clients as well, so rephrase kerneldoc to refer to "client" instead of "GPU" and move the single existing check in an if block specific to PCI_CLASS_DISPLAY_VGA devices. Move documentation on that check from kerneldoc to a comment. (Daniel Vetter) v3: Mandate in kerneldoc that registration of client shall only happen after calling this helper. (Daniel Vetter) v4: Rebase on 412c8f7de011 ("drm/radeon: Return -EPROBE_DEFER when amdkfd not loaded") v5: Some Optimus GPUs use PCI_CLASS_DISPLAY_3D, make sure those are matched as well. (Emil Velikov) v6: The if-condition referring to PCI_BASE_CLASS_DISPLAY may be considered a functional change. Move to a separate commit to keep this a pure refactoring change.

2016-05-23drm/radeon: make radeon_mn_get wait for mmap_sem killableMichal Hocko1-1/+3
radeon_mn_get which is called during ioct path relies on mmap_sem for write. If the waiting task gets killed by the oom killer it would block oom_reaper from asynchronous address space reclaim and reduce the chances of timely OOM resolving. Wait for the lock in the killable mode and return with EINTR if the task got killed while waiting.
