This ioctl will allow us to purge inactive userspace buffers when the
system is running out of contiguous memory.
For now, the purge logic is rather dumb in that it does not try to
release only the amount of BO needed to meet the last CMA alloc request
but instead purges all objects placed in the purgeable pool as soon as
we experience a CMA allocation failure.
Note that the in-kernel BO cache is always purged before the purgeable
cache because those objects are known to be unused while objects marked
as purgeable by a userspace application/library might have to be
restored when they are marked back as unpurgeable, which can be
expensive.

At least when they have vblank support they need to call this, or the
vblank core will happily call into their crtc->enable_vblank callback
even when the crtc is off. Which leads to a boom when the clocks are
off on most hardware (besides the inevitable confusion in the
book-keeping).
The consistency checks in drm_vblank.c will then make sure that
vblank_off/on calls are balanced, and if drivers forget to re-enable
it all the commits will stall, so I think we're covered.
It'd be nice to be able to place this check outside of commit helpers,
but tha's not really possible (due to nonblocking commits and all
that). Placing it into atomic helpers should at least cover most
drivers.
Also note that vblank support is still optional (for virtual drivers,
which tend to not have this), check for that.

The default VGA device is normally set in vga_arbiter_add_pci_device() when
we call it for the first enabled device that can be accessed with the
legacy VGA resources ([mem 0xa0000-0xbffff], etc.)
That default device can be overridden by an EFI device that owns the boot
framebuffer. As a fallback, we can also select a VGA device that can't be
accessed via legacy VGA resources, or a VGA device that isn't even enabled.
Factor out this EFI and fallback selection from vga_arb_device_init() into
a separate vga_arb_select_default_device() function. This doesn't change
any behavior, but it untangles the "bridge control possible" checking and
messages from the default device selection.

Daniel Axtens reported that on the HiSilicon D05 board, the VGA device is
behind a bridge that doesn't support PCI_BRIDGE_CTL_VGA, so the VGA arbiter
never selects it as the default, which means Xorg auto-detection doesn't
work.
VGA is a legacy PCI feature: a VGA device can respond to addresses, e.g.,
[mem 0xa0000-0xbffff], [io 0x3b0-0x3bb], [io 0x3c0-0x3df], etc., that are
not configurable by BARs. Consequently, multiple VGA devices can conflict
with each other. The VGA arbiter avoids conflicts by ensuring that those
legacy resources are only routed to one VGA device at a time.
The arbiter identifies the "default VGA" device, i.e., a legacy VGA device
that was used by boot firmware. It selects the first device that:
- is of PCI_CLASS_DISPLAY_VGA,
- has both PCI_COMMAND_IO and PCI_COMMAND_MEMORY enabled, and
- has PCI_BRIDGE_CTL_VGA set in all upstream bridges.
Some systems don't have such a device. For example, if a host bridge
doesn't support I/O space, PCI_COMMAND_IO probably won't be enabled for any
devices below it. Or, as on the HiSilicon D05, the VGA device may be
behind a bridge that doesn't support PCI_BRIDGE_CTL_VGA, so accesses to the
legacy VGA resources will never reach the device.
This patch extends the arbiter so that if it doesn't find a device that
meets all the above criteria, it selects the first device that:
- is of PCI_CLASS_DISPLAY_VGA and
- has PCI_COMMAND_IO or PCI_COMMAND_MEMORY enabled
If it doesn't find even that, it selects the first device that:
- is of class PCI_CLASS_DISPLAY_VGA.
Such a device may not be able to use the legacy VGA resources, but most
drivers can operate the device without those. Setting it as the default
device means its "boot_vga" sysfs file will contain "1", which Xorg (via
libpciaccess) uses to help select its default output device.
This fixes Xorg auto-detection on some arm64 systems (HiSilicon D05 in
particular; see the link below).
It also replaces the powerpc fixup_vga() quirk, albeit with slightly
different semantics: the quirk selected the first VGA device we found, and
overrode that selection with any enabled VGA device we found. If there
were several enabled VGA devices, the *last* one we found would become the
default.
The code here instead selects the *first* enabled VGA device we find, and
if none are enabled, the first VGA device we find.

The backend has a mux to select the destination of the data to output
to. It can select the TCON or the frontends. On the A20, it includes
an option to output to the second TCON. This is not documented in the
user manual, but the vendor kernel uses it nevertheless, so the second
backend outputs to the second TCON.
Although the muxing can be changed on the fly, DRM needs to be able to
group a bunch of layers such that they get switched to another crtc
together. This is because the display backend does the layer compositing,
while the TCON generates the display timings. This constraint is not
supported by DRM.
Here we simply pair up backends and TCONs with the same ID.

So far, we've required all the TCON-connected encoders to call the TCON
enable and disable functions.
This was made this way because in the RGB/LVDS case, the TCON is the CRTC
and the encoder. However, in all the other cases (HDMI, TV, DSI, etc.), we
have another encoder down the road that needs to be programmed.
We also needed to know which channel the encoder is connected to, which is
encoder-specific.
The CRTC's enable and disable callbacks can work just fine for our use
case, and we can get the channel to use just by looking at the type of
encoder, since that is fixed. Implement those callbacks, which will
remove some of the encoder boilerplate.

The commit da82b8785e ("drm/sun4i: add components in breadth first
traversal order") implemented a breadth first traversal of our device tree
nodes graph. However, it was relying on the kernel linked lists, and those
are not really safe for addition.
Indeed, in a single pipeline stage, your first stage (ie, the mixer or
fronted) will be queued, and it will be the final iteration of that list as
far as list_for_each_entry_safe is concerned. Then, during that final
iteration, we'll queue another element (the TCON or the backend) that
list_for_each_entry_safe will not account for, and we will leave the loop
without having iterated over all the elements. And since we won't have
built our components list properly, the DRM driver will be left
non-functional.
We can instead use a kfifo to queue and enqueue components in-order, as was
the original intention. This also has the benefit of removing any dynamic
allocation, making the error handling path simpler too. The only thing
we're losing is the ability to tell whether an element has already been
queued, but that was only needed to remove spurious logs, and therefore
purely cosmetic.
This means that this commit effectively reverses e8afb7b67f ("drm/sun4i:
don't add components that are already in the queue").

The display backend, as well as other peripherals that have a DRAM
clock gate and access DRAM directly, bypassing the system bus,
address the DRAM starting from 0x0, while physical addresses the
system uses starts from 0x40000000 (or 0x20000000 in A80's case).
This issue was witnessed on the Cubietruck, which has 2GB of RAM.
Devices with less RAM function normally due to the DRAM address
wrapping around. CMA seems to always allocate its buffer at a
very high address, close to the end of DRAM.
On a 1GB RAM device, the physical address would be something like
0x78000000. The DRAM address 0x78000000 would access the same DRAM
region as 0x38000000 on a system, as the DRAM address would only
span 0x0 ~ 0x3fffffff. The bit 0x40000000 is non-functional in this
case.
However on the Cubietruck, the DRAM is 2GB. The physical address
is 0x40000000 ~ 0xbfffffff. The buffer would be something like
0xb8000000. But the DRAM address span 0x0 ~ 0x7fffffff, meaning
the buffer address wraps around to 0x38000000, which is wrong.
The correct DRAM address for it should be 0x78000000.
Correct the address configured into the backend layer registers
by PHYS_OFFSET to account for this.

certain monitors.

This patch replace instances of drm_framebuffer_reference/unreference with
*_get/put() suffixes, because get/put is shorter and consistent with the
kernel use of *_get/put suffixes.
This was done with the following Coccinelle script:
@r1@
expression e;
@@
(
-drm_framebuffer_reference(e);
+drm_framebuffer_get(e);

-drm_framebuffer_unreference(e);

drm_gem_cma_create() prints an error message when dma_alloc_wc() fails to
allocate the amount of memory we requested. This can lead to annoying
error messages when CMA is only one possible source of memory for the BO
allocation. Turn this error message into a debug one.
