drm/hisilicon: Don't set drm_device->platformdev

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

drm/nouveau/bl: Assign different names to interfaces

Currently, every backlight interface created by Nouveau uses the same name,
nv_backlight. This leads to a sysfs warning as it tries to create an already
existing folder. 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.

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=86539

v2:
* Switch to using ida for generating unique IDs, as suggested by Ilia Mirkin;
* Allocate backlight name on the stack, as suggested by Ilia Mirkin;
* Move `nouveau_get_backlight_name()` to avoid forward declaration, as
  suggested by Ilia Mirkin;
* Fix reference to bug report formatting, as reported by Nick Tenney.

v3:
* Define a macro for the size of the backlight name, to avoid defining
  it multiple times;
* Use snprintf in place of sprintf.

v4:
* Do not create similarly named interfaces when reaching the maximum

drm/nouveau/ttm: wait for bo fence to signal before unmapping vmas

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.

prevent GPU page faults where a buffer is still being accessed.

7 years agodrm: Add fake controlD* symlinks for backwards compat

drm: Add fake controlD* symlinks for backwards compat

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).

7 years agodrm/amd/powerplay: use pr_debug to print function not implemented message

drm/amd/powerplay: use pr_debug to print function not implemented message

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!"

on which function is not implemented and why.

Rather than using KERN_INFO to print the message everytime the

when debug prints are enabled at runtime.

7 years agodrm/amd/amdgpu: enable GUI idle INT after enabling CGCG

prevents GFX engine generating idle interrupt even
though CGCG is not completely enabled.

Most of the time this goes un-noticed, but on some

system resumes from suspend. The issue is not
