"Mostly small fixes and cleanups for fb drivers (the biggest updates
are for udlfb and pxafb drivers). This also adds deferred console
takeover support to the console code and efifb driver.Summary:
- add support for deferred console takeover, when enabled defers
fbcon taking over the console from the dummy console until the
first text is displayed on the console - together with the "quiet"
kernel commandline option this allows fbcon to still be used
together with a smooth graphical bootup (Hans de Goede)- improve console locking debugging code (Thomas Zimmermann)
- copy the ACPI BGRT boot graphics to the framebuffer when deferred
console takeover support is used in efifb driver (Hans de Goede)- update udlfb driver - fix lost console when the user unplugs a USB
adapter, fix the screen corruption issue, fix locking and add some
performance optimizations (Mikulas Patocka)- update pxafb driver - fix using uninitialized memory, switch to
devm_* API, handle initialization errors and add support for
lcd-supply regulator (Daniel Mack)- add support for boards booted with a DeviceTree in pxa3xx_gcu
driver (Daniel Mack)- rename omap2 module to omap2fb.ko to avoid conflicts with omap1
driver (Arnd Bergmann)- enable ACPI-based enumeration for goldfishfb driver (Yu Ning)
- fix goldfishfb driver to make user space Android code use 60 fps
(Christoffer Dall)- print big fat warning when nomodeset kernel parameter is used in
vgacon driver (Lyude Paul)- remove VLA usage from fsl-diu-fb driver (Kees Cook)
- misc fixes (Julia Lawall, Geert Uytterhoeven, Fredrik Noring,
Yisheng Xie, Dan Carpenter, Daniel Vetter, Anton Vasilyev, Randy

This patch changes udlfb so that it may reallocate the framebuffer when
setting higher-resolution mode. If we boot the system without monitor
attached, udlfb creates a framebuffer with the size 800x600. This patch
makes it possible to select higher videomode with the fbset command when
a monitor is attached.Note that there is no reliable way to prevent the system from touching the
old framebuffer, so we must not free it. We add it to the list
dlfb->deferred_free and free it when the driver is unloaded.Signed-off-by: Mikulas Patocka

The default delay 5 jiffies is too much when the kernel is compiled with
HZ=100 - it results in jumpy cursor in Xwindow.In order to find out the optimal delay, I benchmarked the driver on
1280x720x30fps video. I found out that with HZ=1000, 10ms is acceptable,
but with HZ=250 or HZ=300, we need 4ms, so that the video is played
without any frame skips.This patch changes the delay to this value.

The defio subsystem overwrites the method fb_osp->mmap. That method is
stored in module's static data - and that means that if we have multiple
diplaylink adapters, they will over write each other's method.In order to avoid interference between multiple adapters, we copy the
fb_ops structure to a device-local memory.Signed-off-by: Mikulas Patocka

The udlfb driver reprograms the hardware everytime the user switches the
console, that makes quite unusable when working on the console.This patch makes the driver remember the videomode we are in and avoid
reprogramming the hardware if we switch to the same videomode.We mask the "activate" field and the "FB_VMODE_SMOOTH_XPAN" flag when
comparing the videomode, because they cause spurious switches when
switching to and from the Xserver.Signed-off-by: Mikulas Patocka

I observed that the performance of the udl fb driver degrades over time.
On a freshly booted machine, it takes 6 seconds to do "ls -la /usr/bin";
after some time of use, the same operation takes 14 seconds.The reason is that the value of "limit_sem" decays over time.
The udl driver uses a semaphore "limit_set" to specify how many free urbs
are there on dlfb->urbs.list. If the count is zero, the "down" operation
will sleep until some urbs are added to the freelist.In order to avoid some hypothetical deadlock, the driver will not call
"up" immediately, but it will offload it to a workqueue. The problem is
that if we call "schedule_delayed_work" on the same work item multiple
times, the work item may only be executed once.This is happening:
* some urb completes
* dlfb_urb_completion adds it to the free list
* dlfb_urb_completion calls schedule_delayed_work to schedule the function
dlfb_release_urb_work to increase the semaphore count
* as the urb is on the free list, some other task grabs it and submits it
* the submitted urb completes, dlfb_urb_completion is called again
* dlfb_urb_completion calls schedule_delayed_work, but the work is already
scheduled, so it does nothing
* finally, dlfb_release_urb_work is called, it increases the semaphore
count by 1, although it should increase it by 2So, the semaphore count is decreasing over time, and this causes gradual
performance degradation.Note that in the current kernel, the "up" function may be called from
interrupt and it may race with the "down" function called by another
thread, so we don't have to offload the call of "up" to a workqueue at
all. This patch removes the workqueue code. The patch also changes
"down_interruptible" to "down" in dlfb_free_urb_list, so that we will
clean up the driver properly even if a signal arrives.With this patch, the performance of udlfb no longer degrades.

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.By default all files without license information are under the default
license of the kernel, which is GPL version 2.Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if

Pull drm u pdates from Dave Airlie:
"This is the main drm pull request for v4.12. Apart from two fixes
pulls, everything should have been in drm-next for at least 2 weeks.The biggest thing in here is AMD released the public headers for their
upcoming VEGA GPUs. These as always are quite a sizeable chunk of
header files. They've also added initial non-display support for those
GPUs, though they aren't available in production yet.Otherwise it's pretty much normal.
New bridge drivers:
- megachips-stdpxxxx-ge-b850v3-fw LVDS->DP++
- generic LVDS bridge support.Core:
- Displayport link train failure reporting to userspace
- debugfs interface cleaned up
- subsystem TODO in kerneldoc now
- Extended fbdev support (flipping and vblank wait)
- drm_platform removed
- EDP CRC support in helper

Few parts of kernel define their own macro for aligning down so provide
a common define for this, with the same usage and assumptions as existing
ALIGN.Convert also three existing implementations to this one.

DECON in case of video mode generates interrupt by default at start
of vertical back porch. As this interrupt is used to generate VBLANK
events more optimal point is start of vertical front porch.Signed-off-by: Inki Dae
-
Current implementation of event handling assumes that vblank interrupt is
always called at the right time. It is not true, it can be delayed due to
various reasons. As a result different races can happen. The patch fixes
the issue by using hardware frame counter present in DECON to serialize
vblank and commit completion events.Signed-off-by: Andrzej Hajda

The IPUv3 can read 8-bit alpha values from a separate IDMAC channel driven
by the Alpha Transparency Controller (ATC) for the graphics IDMAC channels.
This allows to reduce memory bandwidth via a conditional read mechanism or
to support planar YUV formats with alpha transparency.Signed-off-by: Philipp Zabel
-
When disabling the foreground DP channel during a modeset, the DC is
already disabled without waiting for end of frame. There is no reason
to wait for a frame boundary before updating the DP registers in that
case.
Add support to apply updates immediately. No functional changes, yet.Signed-off-by: Philipp Zabel

Some registers should be programmed differently in interlace mode.
Additionally IP does not signal stop state properly in interlaced
