Every drm driver calls framebuffer_alloc, fb_alloc_cmap,
unregister_framebuffer, fb_dealloc_cmap and framebuffer_release in
order to emulate fbdev support.
Create drm_fb_helper functions that perform the above operations.
This is part of an effort to prevent drm drivers from calling fbdev
functions directly. It also removes repetitive code from drivers.
There are some drivers that call alloc_apertures after framebuffer_alloc
and some that don't. Make the helper always call alloc_apertures. This
would make certain drivers allocate memory for apertures but not use
them. Since it's a small amount of memory, it shouldn't be an issue.

This is required for DPMS to work correctly, during a modeset
the DPMS property should be turned off, unless the state is
crtc is made active in which case it should be set to DPMS on.
Changes since v1:
- Set DPMS to off when a connector is removed from a crtc too.
- Update the legacy dpms property too.
- Add an exception for the legacy dpms paths, it updates its own state.
Changes since v2:
- Do not preserve dpms property.

This is required to properly handle failing dpms calls.
When making a wait in i915 interruptible, I've noticed
that the dpms sequence could fail with -ERESTARTSYS because
it was waiting interruptibly for flips. So from now on
allow drivers to fail in their connector dpms callback.
Encoder and crtc dpms callbacks are unaffected.

This can be a separate case from mode_changed, when connectors stay the

Two nice things here:
- drm_dev_register will truly register everything in the right order
if the driver doesn't have a ->load callback. Before this we had to
init the primary mode_group after the device nodes where already
registered.
- Less things to keep track of when reworking the connector locking,
yay!

It's been dead code since forever since mode groups haven't ever been
implemented. On top of that it's also been non-functional since we
only ever filtered the getresources ioctl and not any of the others
nor the mode object lookup code.
Given overwhelming evidence it looks like this isn't a feature we
need, hence remove it.

This function takes two locks, both of them the wrong ones. This

Now that we also grab the connection_mutex and so fixed the race with
atomic modeset we can use the iterator there too.
The other special case is drm_connector_unplug_all which would have a
locking inversion with the sysfs store/show functions if we'd grab the
mode_config.mutex around the unplug. We could just grab
connection_mutex instead, but that's a bit too much a dirty trick for
my taste. Also it's only used by udl, which doesn't do any other kind
of connector hotplugging, so should be race-free. Hence just stick
with a comment for now.

Similar with the i915 take all modeset locks for mst hotplug. This is
needed to make sure radeon holds both mode_config.mutex and
mode_config.connection_mutex when updating the connector_list, which
is the new (interim) locking regime we want for that.

While auditing various users of the connector/encoder lists I realized
that the atomic code is a very prolific user of them. And it only ever
grabs the mode_config->connection_mutex, but not the
mode_config->mutex like all the other code walking encoder/connector
lists.
The problem is that we can't grab the mode_config.mutex late in atomic
code since that would lead to locking inversions. And we don't want to
grab it unconditionally like the legacy set_config modeset path since
that would render all the fine-grained locking moot.
Instead just grab more locks in the dp mst hotplug code. Note that
drm_connector_init (which is the one adding the connector to these
lists) already uses drm_modeset_lock_all.
The other reason for grabbing all locks is that the dpms off in the
unplug function amounts to a modeset, so better to take all required
locks for that.

drm_fb_helper_single_add_all_connectors
This is now truly only duct-tape to keep locking checks happy since
calling this function when hpd or polling are already enabled is a
bug. The fbdev helper can't cope with hotplug changes yet at this
point, only after that.
Otoh a bit more robustness in this function can't hurt, and with this
fbdev can actually cope with hotplug changes. And it's also more
consistent with the connector hotadd/remove dp mst needs to do.
Therefore document this as new official behavior.

So on first looks this seems superflous since drivers should ensure
correct ordering to not make this a problem. Otoh ordering constraints
between hdp, fbdev load and enabling polling are already tricky on
some hardware and it helps to be more robust.
But the real goal is to just shut up a locking WARN_ON I'd like to
add, which means init code gets some additional locks just for
uniformity.
v2: Also grab the lock for the public poll_enable, not just poll_init
which is used for resume, with the same justification.

And roll them out across drm_* files. The point here isn't code
prettification (it helps with that too) but that some of these lists
aren't static any more. And having macros will gives us a convenient
place to put locking checks into.

This patch adds the gfx8 interface file between amdgpu and amdkfd. This
interface file is currently in use when running on a Carrizo-based
system.
The interface itself is represented by a pointer to struct
kfd_dev. The pointer is located inside amdgpu_device structure.
All the register accesses that amdkfd need are done using this
interface. This allows us to avoid direct register accesses in
amdkfd proper, while also allows us to avoid locking between
amdkfd and amdgpu.
The single exception is the doorbells that are used in both of
the drivers. However, because they are located in separate pci
bar pages, the danger of sharing registers between the drivers
is minimal.
Having said that, we are planning to move the doorbells as well
to amdgpu.

This patch adds the gfx7 interface file between amdgpu and amdkfd. This
interface file mirrors (some) of the functions in radeon_kfd.c
(the interface file between radeon and amdkfd).
The gfx7 interface is used when it is run on a Kaveri-based system.
This interface file was used for bring-up of amdkfd on amdgpu and for
debugging purposes. For users who would like to run HSA on Kaveri, please
use the radeon graphic driver.
Note: CONFIG_DRM_AMDGPU_CIK must be selected for amdgpu to handle Kaveri.
v2: removed MTYPE_NONCACHED enum definition as it is defined in another
patch

This patch adds an interface file between amdgpu and amdkfd. This
interface file is H/W agnostic, thus containing functions that
operate the same for any AMD APU/GPU H/W generation.
The functions in this interface mirror (some) of the functions in
radeon_kfd.c (the radeon<-->amdkfd interface file). The main functions
are:
- amdgpu_amdkfd_init - initialize the amdkfd module
- amdgpu_amdkfd_load_interface - load the H/W interface according to the
currently probed device
- amdgpu_amdkfd_device_probe - probe the device in amdkfd
- amdgpu_amdkfd_device_init - initialize the device in amdkfd
- amdgpu_amdkfd_interrupt - call the ISR of amdkfd
- amdgpu_amdkfd_suspend - suspend callback from amdgpu
- amdgpu_amdkfd_resume - resume callback from amdgpu
This patch also modifies the relevant amdgpu files, to use this new
interface.

This patch splits the KGD_ENGINE_SDMA to KGD_ENGINE_SDMA1 and
KGD_ENGINE_SDMA2 to match CZ definitions.

Calls to set_memory_wb() incure heavy TLB flush and IPI cost. To
minimize those wait until pool grow beyond batch size before
draining the pool.

Current code never allowed the page pool to actualy fill in anyway.
This fix it, so that we only start freeing page from the pool when
we go over the pool size.
Changed since v1:
- Move the page batching optimization to its separate patch.
Changed since v2:
- Do not remove code part of the batching optimization with
this patch.
- Better commit message.
