Pull drm updates from Dave Airlie:
"Okay this is the big one, I was stalled on the fbdev pull req as I
stupidly let fbdev guys merge a patch I required to fix a warning with
some patches I had, they ended up merging the patch from the wrong
place, but the warning should be fixed. In future I'll just take the
patch myself!Outside drm:
There are some snd changes for the HDMI audio interactions on haswell,
they've been acked for inclusion via my tree. This relies on the
wound/wait tree from Ingo which is already merged.Major changes:
AMD finally released the dynamic power management code for all their
GPUs from r600->present day, this is great, off by default for now but
also a huge amount of code, in fact it is most of this pull request.Since it landed there has been a lot of community testing and Alex has
sent a lot of fixes for any bugs found so far. I suspect radeon might
now be the biggest kernel driver ever :-P p.s. radeon.dpm=1 to enable
dynamic powermanagement for anyone.New drivers:
Renesas r-car display unit.
Other highlights:
- core: GEM CMA prime support, use new w/w mutexs for TTM
reservations, cursor hotspot, doc updates
- dvo chips: chrontel 7010B support
- i915: Haswell (fbc, ips, vecs, watermarks, audio powerwell),
Valleyview (enabled by default, rc6), lots of pll reworking, 30bpp
support (this time for sure)
- nouveau: async buffer object deletion, context/register init
updates, kernel vp2 engine support, GF117 support, GK110 accel
support (with external nvidia ucode), context cleanups.
- exynos: memory leak fixes, Add S3C64XX SoC series support, device
tree updates, common clock framework support,
- qxl: cursor hotspot support, multi-monitor support, suspend/resume
support
- mgag200: hw cursor support, g200 mode limiting
- shmobile: prime support
- tegra: fixes mostlyI've been banging on this quite a lot due to the size of it, and it
seems to okay on everything I've tested it on."* 'drm-next' of git://people.freedesktop.org/~airlied/linux: (811 commits)

The old code allowed very strange memory types. Now it works like
all the other video drivers: ioremap_wc is used unconditionally,
and MTRRs are set if PAT is unavailable (unless MTRR is disabled
by a module parameter).UC, WB, and WT support is gone. If there are MTRR conflicts that prevent
addition of a WC MTRR, adding a non-conflicting MTRR is pointless; it's
better to just turn off MTRR support entirely.As an added bonus, any MTRR added is freed on unload.

Enables page fault based detection of mmap writes to the framebuffer,
which allows standard fbdev apps (like the generic fbdev xorg driver)
to work on DisplayLink devices.Not all bugs are shaken out of the fb_defio path of udlfb, but it's
tantalizingly close, so this seems a good time to enable by default.Alternatively, option can be disabled when running with an xorg driver
that can more directly communicate damaged regions of the framebuffer
via IOCTL. This is a simpler, higher perf option, when available.Signed-off-by: Bernie Thompson

By default, udlfb allocates a 2nd buffer to shadow what's across
the bus on the USB device. It can operate without this shadow,
but then it cannot tell which pixels have changed, and must send all.Saves host memory, but worsens the USB 2.0 bus bottleneck.
This option allows users in very low memory situations (e.g.
bifferboard) to optionally turn off this shadow framebuffer.Signed-off-by: Stuart Hopkins

The video= parameter of the DRM drivers supports some additional flags that
the normal fb drivers do not have. They also allow to limit these flags to
specific outputs. Both things were previously undocumented.Also the parsing of the line had some oddities:
-A lot of misplaced options were silently ignored or partly rejected instead
of stopping the parsing immediately
-The 'R' option is documented to follow the 'M' option if specified. It is not
documented that 'M' is needed to specify 'R' (also this is the case for normal
fb drivers). In fact the code is correct for normal fb drivers but wrong for
DRM ones.
The old code allowed 'R' only _before_ 'M' (since it parses backwards) and only
if 'M' is given at all which is not needed for the DRM drivers.
-the margins option ('m') was parsed but later ignored even if the later
functions support it.
-specifying multiple enable options at the same time did not lead to an error.
-specifying something bogus for horizontal resolution (i.e. other things as
digits) did not lead to an error but an invalid resolution was used.If any errors are encountered the position of the faulting string is now
printed to the user and the complete mode is ignored. This gives much
more consistent error behaviour.I also removed some useless assignments and changed the local flag variables
to be bool.Signed-off-by: Rolf Eike Beer

udlfb has undergone a fair bit of cleanup recently and is effectively at
the point where it can be liberated from staging purgatory and promoted
to a real driver.The outstanding cleanups are all minor, with some of them dependent on
drivers/video headers, so these will be done incrementally from udlfb's
new home.Requested-by: Bernie Thompson

Below you will find an updated version from the original series bunching all patches into one big patch
updating broken web addresses that are located in Documentation/*
Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult,
the best way to deal with these is to use web.archive.org to locate these addresses that are outdated.
Now there are also some addresses pointing to .spec files some are located, but some(after searching
on the companies site)where still no where to be found. In this case I just changed the address
to the company site this way the users can contact the company and they can locate them for the users.Signed-off-by: Justin P. Mattock

I would like to get rid of option CONFIG_FB_MATROX_MULTIHEAD and just
always enable it. There are many reasons for doing this:* CONFIG_FB_MATROX_MULTIHEAD=y is what all x86 distributions do, so it
definitely works or we would know by now.* Building the matroxfb driver with CONFIG_FB_MATROX_MULTIHEAD not set
results in the following build warning:drivers/video/matrox/matroxfb_crtc2.c: In function 'matroxfb_dh_open':
drivers/video/matrox/matroxfb_crtc2.c:265: warning: the address of 'matroxfb_global_mxinfo' will always evaluate as 'true'
drivers/video/matrox/matroxfb_crtc2.c: In function 'matroxfb_dh_release':
drivers/video/matrox/matroxfb_crtc2.c:285: warning: the address of 'matroxfb_global_mxinfo' will always evaluate as 'true'This is nothing to be worried about, the driver will work fine, but build
warnings are still annoying.* The trick to get multihead support without CONFIG_FB_MATROX_MULTIHEAD,
which is described in the config help text, no longer works: you can't
load the same kernel module more than once.* I fail to see how CONFIG_FB_MATROX_MULTIHEAD=y would make the code
significantly slower, contrary to what the help text says. A few extra
parameters on the stack here and there can't really slow things down in
comaprison to the rest of the code, and register access.* The driver built without CONFIG_FB_MATROX_MULTIHEAD is larger than the
driver build with CONFIG_FB_MATROX_MULTIHEAD=y by 8%.* One less configuration option makes things simpler. We add options
all the time, being able to remove one for once is nice. It improves
testing coverage. And I don't think the Matrox adapters are still
popular enough to warrant overdetailed configuration settings.* We should be able to unobfuscate the driver code quite a bit after
this change (patches follow.)Signed-off-by: Jean Delvare

A tridentfb driver has all the functionality of the cyblafb driver without
the bugs of the latter.Changes to the tridentfb driver:
- FBINFO_READS_FAST added to the tridentfb. The cyblafb used a blitter
for scrolling which is faster than color expansion on Cyberblade
chipsets. The blitter is slower on a discrete Blade3D core. Use the
blitter for scrolling in the tridentfb only for integrated Blade3D
cores. Now, scrolling speed is about equal for the tridentfb and the
cyblafb.- a copyright notice addition is done on request of Jani Monoses (the
first author of the tridentfb).Tested on AGP Blade3D card and PCChips

PXA27x and later processors support overlay1 and overlay2 on-top of the
base framebuffer (although under-neath the base is also possible). They
support palette and no-palette RGB formats, as well as YUV formats (only
available on overlay2). These overlays have dedicated DMA channels and
behave in a similar way as a framebuffer.This heavily simplified and re-structured work is based on the original
pxafb_overlay.c (which is pending for mainline merge for a long time).The major problems with this pxafb_overlay.c are (if you are interested
in the history):1. heavily redundant (the control logics for overlay1 and overlay2 are
actually identical except for some small operations, which are now
abstracted into a 'pxafb_layer_ops' structure)2. a lot of useless and un-tested code (two workarounds which are now
fixed on mature silicons)3. cursorfb is actually useless, hardware cursor should not be used
this way, and the code was actually un-tested for a long time.The code in this patch should be self-explanatory, I tried to add minimum
comments. As said, this is basically simplified, there are several things
still on the pending list:1. palette mode is un-supported and un-tested (although re-using the
palette code of the base framebuffer is actually very easy now with
previous clean-up patches)2. fb_pan_display for overlay(s) is un-supported
3. the base framebuffer can actually be abstracted by 'pxafb_layer' as
well, which will help further re-use of the code and keep a better
and consistent structure. (This is the reason I named it 'pxafb_layer'
instead of 'pxafb_overlay' or something alike)See Documentation/fb/pxafb.txt for additional usage information.

The amount of video memory size is decided according to the following
order:1. x x by default, which is the backward
compatible way2. size specified in platform data
3. size specified in module parameter 'options' string or specified in
kernel boot command line (see updated Documentation/fb/pxafb.txt)And now since the memory is allocated from system memory, the pxafb_mmap
can be removed and the default fb_mmap() should be working all right.Also, since we now have introduced the 'struct pxafb_dma_buff' for DMA
descriptors and palettes, the allocation can be separated cleanly.NOTE: the LCD DMA actually supports chained transfer (i.e. page-based
transfers), to simplify the logic and keep the performance (with less
TLB misses when accessing from memory mapped user space), the memory
is allocated by alloc_pages_*() to ensures it's physical contiguous.Signed-off-by: Eric Miao

I'd be able to use it to get a console at the native 1024x600 resolution
