2016-12-13drm/etnaviv: Use drm_dev_unref, not drm_put_devDaniel Vetter1-1/+1
drm_put_dev is the old midlayer-broken device cleanup function, but etnaviv has a proper unbind function which first unregisters and then drops the final reference. No functional change since drm_dev_unregister happens to be idempotent.

- Again move the information relevant for driver writers next to the callbacks. - Put the overview and userspace interface documentation into a DOC: section within the code. - Remove the text that mmap needs to be coherent - since the DMA_BUF_IOCTL_SYNC landed that's no longer the case.

2016-12-13drm/hisilicon: Don't set drm_device->platformdevDaniel Vetter3-15/+8
It's deprecated and only should be used by drivers which still use drm_platform_init, not by anyone else. And indeed it's entirely unused and can be nuked. This required a bit more fudging, but I guess kirin_dc_ops really wants to operate on the platform_device, not something else. Also bonus points for implementing abstraction, and then storing the vfunc in a global variable. v2: Don't break the build soooo badly :( Note that the cleanup function is a bit confused: ade_data was never set as drvdata, and calling drm_crtc_cleanup directly is a bug - this is called indirectly through drm_mode_config_cleanup, which calls into crtc->destroy, which already has the call to drm_crtc_cleanup. Which means we can just nuke it. Note this is the 2nd attempt after the first one failed and had to be reverted again in commit 9cd2e854d61ccfa51686f3ed7b0c917708fc641f Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed Aug 17 13:59:40 2016 +0200 Revert "drm/hisilicon: Don't set drm_device->platformdev" Cc: Xinliang Liu <xinliang.liu@linaro.org> Cc: Xinwei Kong <kong.kongxinwei@hisilicon.com> Cc: Archit Taneja <architt@codeaurora.org> Cc: Sean Paul <seanpaul@chromium.org> Reviewed-by: Sean Paul <seanpaul@chromium.org> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20161209141944.22121-1-daniel.vetter@ffwll.ch
2016-12-13drm: Enforce BKL-less ioctls for modern driversDaniel Vetter1-3/+2
With the last round of changes all ioctls called by modern drivers now have their own locking. Everything else is only allowed for legacy drivers and hence the lack of locking doesn't matter. One exception is nouveau, due to the DRIVER_KMS_LEGACY_CONTEXT flag. But that only works its magic on the context and bufs ioctls. And drm_bufs.c is protected with dev->struct_mutex, and drm_context.c by the same and dev->ctxlist_mutex. That should be all safe, and we can finally mandata drm-bkl-less ioctls for everyone!

2016-12-13drm: setclientcap doesn't need the drm BKLDaniel Vetter1-1/+1
It only updates per-file feature flags. And all the ioctl which change behaviour depending upon these flags (they're all kms features) do _not_ hold the BKL. Therefor this is pure cargo-cult and can be removed. Note that there's a risk that the ioctl will behave inconsistently when userspace is racing with itself, but that's ok. The only thing it's not allowed to do is oops the kernel, and from an audit all places are safe. v2: Clarify that the inconsistency is only when userspace races (Chris).

This patch adds a incremented number to the name, but keeps the initial name as nv_backlight, to avoid possibly breaking userspace; the second interface will be named nv_backlight1, and so on.

2016-12-13drm/nouveau/ttm: wait for bo fence to signal before unmapping vmasBen Skeggs1-0/+1
TTM was changed a while back to allow for pipelining of buffer moves, and part of this was the removal of waiting for a BO to idle before calling move(), placing the responsibility on the driver to do this if required. That's all well and good, except, we make use of move_notify() to handle mapping/unmapping from the GPU VMM as move() isn't called on all paths. This commit adds a wait before unmapping from a VMM in move_notify(), to prevent GPU page faults where a buffer is still being accessed.

This has been on the TODO list for a while now, recovering from things such as attempting to execute a push buffer or touch a semaphore in an unmapped memory area. The only thing required on the HW side here is that the offending channel is removed from the runlist, and *not* a full reset of PFIFO. This used to be a bit messier to handle before the rework to make use of engine topology info, but is apparently now trivial. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2016-12-10drm: Add fake controlD* symlinks for backwards compatDaniel Vetter1-0/+62
We thought that no userspace is using them, but oops libdrm is using them to figure out whether a driver supports modesetting. Check out drmCheckModesettingSupported but maybe don't because it's horrible and totally runs counter to where we want to go with libdrm device handling. The function looks in the device hierarchy for whether controlD* exist using the following format string: /sys/bus/pci/devices/%04x:%02x:%02x.%d/drm/controlD%d The "/drm" subdirectory is the glue directory from the sysfs class stuff, and the only way to get at it seems to through kdev->kobj.parent (when kdev is represents e.g. the card0 chardev instance in sysfs). Git grep says we're not the only ones touching that, so I hope it's ok we dig into such internals - I couldn't find a proper interface for getting at the glue directory. Quick git grep shows that at least -amdgpu, -ati are using this. -modesetting do not, and on -intel it's only about the 4th fallback path for device lookup, which is why this didn't blow up earlier. Oh well, we need to keep it working, and the simplest way is to add a symlink at the right place in sysfs from controlD* to card*. v2: - Fix error path handling by adding if (!minor) return checks (David) - Fix the controlD* numbers to match what's been there (David) - Add a comment what exactly userspace minimally needs. - Correct the analysis for -intel (Chris).

2016-12-08drm/amdgpu: use pin rather than pin_restricted in a few casesAlex Deucher2-2/+2
We don't require a resticted pinning in these cases, so just use plain pin. Reviewed-by: Edward O'Callaghan <funfunctor@folklore1984.net> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2016-12-08drm/amd/powerplay: use pr_debug to print function not implemented messageArindam Nath1-1/+1
For CZ, some function pointers like display_configuration_changed are not set. So when HW manager tries to configure display, we end up with messages like "[ powerplay ] this function not implement!" in the logs. This message is informational, but lacks details on which function is not implemented and why. Rather than using KERN_INFO to print the message everytime the system boots, we rather use pr_debug so that it is only printed when debug prints are enabled at runtime.

2016-12-08drm/atomic: Use active instead of enable in wait_for_vblanks.Maarten Lankhorst1-1/+1
When DPMS was introduced to atomic, vblanks only worked when the crtc was enabled and active. wait_for_vblanks were not converted to check for crtc_state->active, which may cause an attempt for vblank_get to fail. This is probably harmless, but convert from enable to active anyway.
