git://anongit.freedesktop.org/drm-intel into drm-next
So small drm stuff all over for 3.18. Biggest one is the cmdline parsing
from Chris with a few fixes from me to make it work for stupid kernel
configs.
Plus the atomic prep series.
Tested for more than a week in -nightly and Ville/Imre indeed discovered
some fun which is now fixed (and i915 vblank patches postponed since the
fixups need this branch plus drm-intel-next merged together).

i915.ko has a custom fbdev initialisation routine that aims to preserve
the current mode set by the BIOS, unless overruled by the user. The
user's wishes are determined by what, if any, mode is specified on the
command line (via the video= parameter). However, that command line mode
is first parsed by drm_fb_helper_initial_config() which is called after
i915.ko's custom initial_config() as a fallback method. So in order for
us to honour it, we need to move the cmdline parser earlier. If we
perform the connector cmdline parsing as soon as we initialise the
connector, that cmdline mode and forced status is then available even if
the fbdev helper is not compiled in or never called.
We also then expose the cmdline user mode in the connector mode lists.
v2: Rebase after connector->name upheaval.
v3: Adapt mga200 to look for the cmdline mode in the new place. Nicely
simplifies things while at that.
v4: Fix checkpatch.
v5: Select FB_CMDLINE to adapt to the changed fbdev patch.

The following configuration options combination:
CONFIG_DRM_EXYNOS_DP=y
CONFIG_DRM_PTN3460=m
currently leads to the following linker failure:
drivers/built-in.o: In function `exynos_drm_attach_lcd_bridge':
.../drivers/gpu/drm/exynos/exynos_dp_core.c:1004:
undefined reference to `ptn3460_init'
This is because ptn3460_init can't be implemented in a module while
its caller is built into the kernel. So add the proper dependency in
Kconfig so that the above can't happen.
I moved DRM_PTN3460 earlier in Kconfig, next to the I2C helper module
section, so that the user has a chance to select it before moving to
the Exynos-specific section.
IMHO the proper way to solve the problem would be to turn ptn3460 into
a clean I2C driver, similar to the other I2C helper chip drivers. It's
the only way to not sink into impossible-to-guess dependencies. Then
ptn3460 could even be moved together with the other I2C helper chip
drivers.

Add a very simple framework to register and lookup panels. Panel drivers
can initialize a DRM panel and register it with the framework, allowing
them to be retrieved and used by display drivers. Currently only support
for DPMS and obtaining panel modes is provided. However it should be
sufficient to enable a large number of panels. The framework should also
be easily extensible to support more sophisticated kinds of panels such
as DSI.
The framework hasn't been tied into the DRM core, even though it should
be easily possible to do so if that's what we want. In the current
implementation, display drivers can simple make use of it to retrieve a
panel, obtain its modes and control its DPMS mode.
Note that this is currently only tested on systems that boot from a
device tree. No glue code has been written yet for systems that use
platform data, but it should be easy to add.

MIPI DSI bus allows to model DSI hosts and DSI peripherals using the
Linux driver model. DSI hosts are registered by the DSI host drivers.
During registration DSI peripherals will be created from the children
of the DSI host's device tree node. Support for registration from
board-setup code will be added later when needed.
DSI hosts expose operations which can be used by DSI peripheral drivers
to access associated devices.

drm/tegra: Changes for v3.13-rc1
The biggest part of the changes is the decoupling of the host1x and DRM
drivers followed by the move of Tegra DRM back to drivers/gpu/drm/tegra
from whence it came. There is a lot of cleanup as well, and the drivers
can now be properly unloaded and reloaded.
HDMI support for the Tegra114 SoC was contributed by Mikko Perttunen.
gr2d support was extended to Tegra114 and the gr3d driver that has been
in the works for quite some time finally made it in. All pieces to run
an OpenGL driver on top of an upstream kernel are now available.
Support for syncpoint bases was added by Arto Merilainen. This is useful
for synchronizing between command streams from different engines such as
gr2d and gr3d.
Erik Faye-Lund and Wei Yongjun contributed various small fixes. Thanks!

This patch adds support for the pair of LCD controllers on the Marvell
Armada 510 SoCs. This driver supports:
- multiple contiguous scanout buffers for video and graphics
- shm backed cacheable buffer objects for X pixmaps for Vivante GPU
acceleration
- dual lcd0 and lcd1 crt operation
- video overlay on each LCD crt via DRM planes
- page flipping of the main scanout buffers
- DRM prime for buffer export/import
This driver is trivial to extend to other Armada SoCs.
Included in this commit is the core driver with no output support; output
support is platform and encoder driver dependent.

Boots Just Fine (tm)!
The only glitch seems to be that at least on Fedora the boot splash
gets confused and doesn't display much at all.
And since there's no ugly console flickering anymore in between, the
flicker while switching between X servers (VT support is still enabled)
is even more jarring.
Also, I'm unsure whether we don't need to somehow kick out vgacon, now
that nothing else gets in the way. But stuff seems to work, so I
don't care. Also everything still works as well with VGA_CONSOLE=n
Also the #ifdef mess needs a bit of a cleanup, follow-up patches will
do just that.
To keep the Kconfig tidy, extract all the i915 options into its own
file.
v2:
- Rebase on top of the preliminary hw support option and the
intel_drv.h cleanup.
- Shut up warnings in i915_debugfs.c
v3: Use the right CONFIG variable, spotted by Chon Ming.

For drivers which might want to disable fbdev legacy support.
Select the new option in all drivers for now, so this shouldn't result
in any change. Drivers need some work anyway to make fbdev support
optional (if they have it implemented, that is), so the recommended
way to expose this is by adding per-driver options. At least as long
as most drivers don't support disabling the fbdev support.
v2: Update for new drm drivers msm and rcar-du. Note that Rob's msm
driver can already take advantage of this, which allows us to build
msm without any fbdev depencies in the kernel!
v3: Move the MODULE_* stuff from the fbdev helper file to
drm_crtc_helper.c.

The snapdragon chips have multiple different display controllers,
depending on which chip variant/version. (As far as I can tell, current
devices have either MDP3 or MDP4, and upcoming devices have MDSS.) And
then external to the display controller are HDMI, DSI, etc. blocks which
may be shared across devices which have different display controller
blocks.
To more easily add support for different display controller blocks, the
display controller specific bits are split out into a "kms" module,
which provides the kms plane/crtc/encoder objects.
The external HDMI, DSI, etc. blocks are part encoder, and part connector
currently. But I think I will pull in the drm_bridge patches from
chromeos tree, and split them into a bridge+connector, with the
registers that need to be set in modeset handled by the bridge. This
would remove the 'msm_connector' base class. But some things need to be
double checked to make sure I could get the correct ON/OFF sequencing..
This patch adds support for mdp4 crtc (including hw cursor), dtv encoder
(part of MDP4 block), and hdmi.

QXL is a paravirtual graphics device used by the Spice virtual desktop
interface.
The drivers uses GEM and TTM to manage memory, the qxl hw fencing however
is quite different than normal TTM expects, we have to keep track of a number
of non-linear fence ids per bo that we need to have released by the hardware.
The releases are freed from a workqueue that wakes up and processes the
release ring.
releases are suballocated from a BO, there are 3 release categories, drawables,
surfaces and cursor cmds. The hw also has 3 rings for commands, cursor and release handling.
The hardware also have a surface id tracking mechnaism and the driver encapsulates it completely inside the kernel, userspace never sees the actual hw surface
ids.
This requires a newer version of the QXL userspace driver, so shouldn't be
enabled until that has been placed into your distro of choice.

displays, for which support can be added (as I get hw to test on),
and an external i2c HDMI encoder found on some boards.
The display controller supports a single CRTC. And the encoder+

In drivers/usb/Kconfig "config USB_ARCH_HAS_HCD" is within "if USB_SUPPORT"
statement.
In drivers/gpu/drm/Kconfig "config DRM_USB" depends on USB_ARCH_HAS_HCD
but selects USB_SUPPORT which leads to the error for udl Kconfig:
$ yes "" | make oldconfig
scripts/kconfig/conf --oldconfig Kconfig
drivers/gpu/drm/udl/Kconfig:1:error: recursive dependency detected!
drivers/gpu/drm/udl/Kconfig:1: symbol DRM_UDL depends on USB_ARCH_HAS_HCD
drivers/usb/Kconfig:76: symbol USB_ARCH_HAS_HCD depends on USB_SUPPORT
drivers/usb/Kconfig:58: symbol USB_SUPPORT is selected by DRM_USB
drivers/gpu/drm/Kconfig:22: symbol DRM_USB is selected by DRM_UDL
Fix this by changing from select to depends on USB_SUPPORT in
"config DRM_USB".
This is a follow-up fix to df0b344300724e00db9fff7eb6406eb91f450b91
in Dave's drm-next GIT branch.

DRM_USB selects USB. However, USB depends on USB_SUPPORT and USB_ARCH_HAS_HCD.
Thus, selecting USB_SUPPORT in Kconfig avoids the following warning
(detected when DisplayLink was selected using exynos4_defconfig):
warning: (MOUSE_APPLETOUCH && MOUSE_BCM5974 && MOUSE_SYNAPTICS_USB && JOYSTICK_XPAD && TABLET_USB_ACECAD && TABLET_USB_AIPTEK && TABLET_USB_HANWANG && TABLET_USB_KBTAB && TABLET_USB_WACOM && TOUCHSCREEN_USB_COMPOSITE && INPUT_ATI_REMOTE2 && INPUT_KEYSPAN_REMOTE && INPUT_POWERMATE && INPUT_YEALINK && INPUT_CM109 && RC_ATI_REMOTE && IR_IMON && IR_MCEUSB && IR_REDRAT3 && IR_STREAMZAP && IR_IGUANA && DRM_USB) selects USB which has unmet direct dependencies (USB_SUPPORT && USB_ARCH_HAS_HCD)

Fix config warning:
warning: ( ... && DRM_USB) selects USB which has unmet direct dependencies
(USB_SUPPORT && USB_ARCH_HAS_HCD)
and build error:
ERROR: "usb_speed_string" [drivers/usb/core/usbcore.ko] undefined!
by adding the missing dependency on USB_ARCH_HAS_HCD to DRM_UDL and DRM_USB.
This exposes:

drivers/video/Kconfig:385: symbol FB_CYBER2000_DDC depends on FB_CYBER2000
drivers/video/Kconfig:373: symbol FB_CYBER2000 depends on FB
which is due to drivers/usb/Kconfig:
config USB_ARCH_HAS_OHCI
...
default y if ARCH_PNX4008 && I2C
Fix by dropping I2C from the above dependency; logic is that this is not a
platform dependency but a configuration dependency: the _architecture_ still
supports USB even is I2C is not selected.

This is the initial driver for emulated cirrus GPU found in qemu.
This driver only supports the emulated GPU and doesn't attempt
to bind to any real cirrus GPUs.
This driver is intended to be used with xf86-video-modesetting in userspace.
It requires at least version 0.3.0
This follow the same design as ast and mgag200, and is based on work
done by Matthew Garrett previously.
This GPU has no hw cursor, and it can't scanout 32-bpp, only packed 24-bpp.
i.e. it sucks.

This is a driver for the G200 server engines chips,
it doesn't driver any of the Matrix G series desktop cards.
It will bind to G200 SE A,B, G200EV, G200WB, G200EH and G200ER cards.
Its based on previous work done my Matthew Garrett but remodelled
to follow the same style and flow as the AST server driver. It also
works along the same lines as the AST server driver wrt memory management.
There is no userspace driver planned, xf86-video-modesetting should be used.
It also appears these GPUs have no ARGB hw cursors.
v2: add missing tagfifo reset + G200 SE memory bw setup pieces.

This is the initial driver for the Aspeed Technologies chips found in
servers. This driver supports the AST 2000, 2100, 2200, 2150 and 2300. It
doesn't support the AST11xx due to lack of hw to test it on, and them requiring
different codepaths.
This driver is intended to be used with xf86-video-modesetting in userspace.
This driver has a slightly different design than other KMS drivers, but
future server chips will probably share similiar setup. As these GPUs commonly
have low video RAM, it doesn't make sense to put the kms console in VRAM
always. This driver places the kms console into system RAM, and does dirty
updates to a copy in video RAM. When userspace sets a new scanout buffer,
it forcefully evicts the video RAM console, and X can create a framebuffer
that can use all of of video RAM.
This driver uses TTM but in a very simple fashion to control the eviction
to system RAM of the console, and multiple servers.
v2: add s/r support, fix Kconfig.

This adds the basic drm dma-buf interface layer, called PRIME. This
commit doesn't add any driver support, it is simply and agreed upon starting
point so we can work towards merging driver support for the next merge window.
Current drivers with work done are nouveau, i915, udl, exynos and omap.
The main APIs exposed to userspace allow translating a 32-bit object handle
to a file descriptor, and a file descriptor to a 32-bit object handle.
The flags value is currently limited to O_CLOEXEC.
Acknowledgements:
Daniel Vetter: lots of review
Rob Clark: cleaned up lots of the internals and did lifetime review.
v2: rename some functions after Chris preferred a green shed
fix IS_ERR_OR_NULL -> IS_ERR
v3: Fix Ville pointed out using buffer + kmalloc
v4: add locking as per ickle review
v5: allow re-exporting the original dma-buf (Daniel)

Broken monitors and/or broken graphic boards may send erroneous or no
EDID data. This also applies to broken KVM devices that are unable to
correctly forward the EDID data of the connected monitor but invent
their own fantasy data.
This patch allows to specify an EDID data set to be used instead of
probing the monitor for it. It contains built-in data sets of frequently
used screen resolutions. In addition, a particular EDID data set may be
provided in the /lib/firmware directory and loaded via the firmware
interface. The name is passed to the kernel as module parameter of the
drm_kms_helper module either when loaded
options drm_kms_helper edid_firmware=edid/1280x1024.bin
or as kernel commandline parameter
drm_kms_helper.edid_firmware=edid/1280x1024.bin
It is also possible to restrict the usage of a specified EDID data set
to a particular connector. This is done by prepending the name of the
connector to the name of the EDID data set using the syntax
edid_firmware=[<connector>:]<edid>
such as, for example,
edid_firmware=DVI-I-1:edid/1920x1080.bin
in which case no other connector will be affected.
The built-in data sets are
Resolution Name
--------------------------------
1024x768 edid/1024x768.bin
1280x1024 edid/1280x1024.bin
1680x1050 edid/1680x1050.bin
1920x1080 edid/1920x1080.bin
They are ignored, if a file with the same name is available in the
/lib/firmware directory.
The built-in EDID data sets are based on standard timings that may not
apply to a particular monitor and even crash it. Ideally, EDID data of
the connected monitor should be used. They may be obtained through the
drm/cardX/cardX-<connector>/edid entry in the /sys/devices PCI directory
of a correctly working graphics adapter.
It is even possible to specify the name of an EDID data set on-the-fly
via the /sys/module interface, e.g.
echo edid/myedid.bin >/sys/module/drm_kms_helper/parameters/edid_firmware
The new screen mode is considered when the related kernel function is
called for the first time after the change. Such calls are made when the
X server is started or when the display settings dialog is opened in an
already running X server.

In order to satisfy all the various Kconfig options between
USB and DRM, we need to split the USB code out into a separate module
and export symbols to it.

This is an initial drm/kms driver for the displaylink devices.
Supports fb_defio,
supports KMS dumb interface
supports 24bpp via conversion to 16bpp, hw can do this better.
supports hot unplug using new drm core features.
On an unplug, it disables connector polling, unplugs connectors
from sysfs, unplugs fbdev layer (using Kay's API), drops all the
USB device URBs, and call the drm core to unplug the device.
This driver is based in large parts on udlfb.c so I've licensed
it under GPLv2.
