a09d431f34 drm/radeon: fix load detect on rn50 with hardcoded EDIDs.
When the force changes went in back in 3.3.0, we ended up returning
disconnected in the !force case, and the connected in when forced,
as it hit the hardcoded check.

Fix it so all exits go via the hardcoded check and stop spurious
modesets on platforms with hardcoded EDIDs.

Merge tag 'v3.4-rc3' into drm-intel-next-queued

Backmerge Linux 3.4-rc3 into drm-intel-next to resolve a few things
that conflict/depend upon patches in -rc3:
- Second part of the Sandybridge workaround series - it changes some
  of the same registers.
- Preparation for Chris Wilson's fencing cleanup - we need the fix
  from -rc3 merged before we can move around all that code.
- Resolve the gmbus conflict - gmbus has been disabled in 3.4 again,
  but should be enabled on all generations in 3.5.

On coherent systems (not-AGP) the IB should be in cached memory so should
be just as fast, so we can avoid copying to temporary pages and just use it
directly.

provides minor speedups on rv530: gears ~1820->1860, ipers: 29.9->30.6,

ed2d265d12 The following text was taken from the original review request:
"[RFC - PATCH 0/7] consolidation of BUG support code."
 		https://lkml.org/lkml/2012/1/26/525
 --
 
 The changes shown here are to unify linux's BUG support under
 the one <linux/bug.h> file.  Due to historical reasons, we have
 some BUG code in bug.h and some in kernel.h -- i.e. the support for
 BUILD_BUG in linux/kernel.h predates the addition of linux/bug.h,
 but old code in kernel.h wasn't moved to bug.h at that time.  As
 a band-aid, kernel.h was including <asm/bug.h> to pseudo link them.
 
 This has caused confusion[1] and general yuck/WTF[2] reactions.
 Here is an example that violates the principle of least surprise:
 
       CC      lib/string.o
       lib/string.c: In function 'strlcat':
       lib/string.c:225:2: error: implicit declaration of function 'BUILD_BUG_ON'
       make[2]: *** [lib/string.o] Error 1
       $
       $ grep linux/bug.h lib/string.c
       #include <linux/bug.h>
       $
 
 We've included <linux/bug.h> for the BUG infrastructure and yet we
 still get a compile fail!  [We've not kernel.h for BUILD_BUG_ON.]
 Ugh - very confusing for someone who is new to kernel development.
 
 With the above in mind, the goals of this changeset are:
 
 1) find and fix any include/*.h files that were relying on the
    implicit presence of BUG code.
 2) find and fix any C files that were consuming kernel.h and
    hence relying on implicitly getting some/all BUG code.
 3) Move the BUG related code living in kernel.h to <linux/bug.h>
 4) remove the asm/bug.h from kernel.h to finally break the chain.
 
 During development, the order was more like 3-4, build-test, 1-2.
 But to ensure that git history for bisect doesn't get needless
 build failures introduced, the commits have been reorderd to fix
 the problem areas in advance.

be53bfdb80 Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm main changes from Dave Airlie:
 "This is the main drm pull request, I'm probably going to send two more
  smaller ones, will explain below.

  This contains a patch that is also in the fbdev tree, but it should be
  the same patch, it added an API for hot unplugging framebuffer
  devices, and I need that API for a new driver.

  It also contains some changes to the i2c tree which Jean has acked,
  and one change to moorestown platform stuff in x86.

  Highlights:
   - new drivers: UDL driver for USB displaylink devices, kms only,
     should support correct hotplug operations.
   - core: i2c speedups + better hotplug support, EDID overriding via
     firmware interface - allows user to load a firmware for a broken
     monitor/kvm from userspace, it even has documentation for it.
   - exynos: new HDMI audio + hdmi 1.4 + virtual output driver
   - gma500: code cleanup
   - radeon: cleanups, CS optimisations, streamout support and pageflip
     fix
   - nouveau: NVD9 displayport support + more reclocking work
   - i915: re-enabling GMBUS, finish gpu patch (might help hibernation
     who knows), missed irq fixes, stencil tiling fixes, interlaced
     support, aliasesd PPGTT support for SNB/IVB, swizzling for SNB/IVB,
     semaphore fixes

  As well as the usual bunch of cleanups and fixes all over the place.

  I've got two things I'd like to merge a bit later:

   a) AMD support for all their new radeonhd 7000 series GPU and APUs.
      AMD dropped this a bit late due to insane internal review
      processes, (please AMD just follow Intel and let open source guys
      ship stuff early) however I don't want to penalise people who own
      this hardware (since its been on sale for 3-4 months and GPU hw
      doesn't exactly have a lifetime in years) and consign them to
      using closed drivers for longer than necessary.  The changes are
      well contained and just plug into the driver new gpu functionality
      so they should be fairly regression proof.  I just want to give
      them a bit of a run on the hw AMD kindly sent me.

   b) drm prime/dma-buf interface code.  This is just infrastructure
      code to expose the dma-buf stuff to drm drivers and to userspace.
      I'm not planning on pushing any driver support in this cycle
      (except maybe exynos), but I'd like to get the infrastructure code
      in so for the next cycle I can start getting the driver support
      into the individual drivers.  We have started driver support for
      i915, nouveau and udl along with I think exynos and omap in

      pulled into your tree first since it needs the latest interfaces

Fix up trivial conflicts in arch/x86/platform/mrst/mrst.c due to the new

dfcf5f3652 drm/radeon/kms: add support for the CONST IB to the CS ioctl
This adds a new chunk id to the CS ioctl to support the
INDIRECT_BUFFER_CONST packet.

On SI, the CP adds a new engine called the CE (Constant Engine)
which runs simulatenously with the DE (Drawing Engine, formerly
called the ME).  This allows the CP to process two related IBs
simultaneously.  The CE is tasked with loading the constant data
(constant buffers, resource descriptors, samplers, etc.) while
the DE loads context register state and issues drawing commands.
It's up to the userspace application to sychronize the CE and the
DE using special synchronization packets.

11fe126625 drm/radeon/kms: reduce probe latency on digital connectors
On a system with one HDMI and one VGA connector the latter
causes output polling to run every ten seconds. This causes
full EDID re-fetch on every poll and approx. 100ms rendering
stalls are experienced by full screen page-flipping applications.
Optimisation is to trust HPD sense on R600+ ASICs and to skip
doing these expensive probes unless HPD sense has changed.

f48bb04a56 drivers/gpu/drm/radeon/radeon_cs.c: eliminate possible double free
The function radeon_cs_parser_init is only called from two places, in
drivers/gpu/drm/radeon/radeon_cs.c and drivers/gpu/drm/radeon/r600_cs.c.
In each case, if the call fails another function is called that frees all
of the kdata and dpage information in the chunks array.  So this
information should not be freed in radeon_cs_parser_init as well.

aaefcd4284 drm/radeon: deal with errors from framebuffer init path.
We've been getting occasional oops running a 32-bit kernel on a certain
system in our RHEL test hw. It appears that we fail to get sufficent ioremap
space for the framebuffer, and this leads to an oops.

This patch should fix the oops and leave a message in the logs we can
check for.

A future fix would probably to resize the console to a size that we can
ioremap.

81ffbbedc3 drm/radeon: fix deferred page-flip detection logic on Avivo-based ASICs
This fixes page-flip-related flickering observed on Iconia Tab W500.

The update_pending status returned by radeon_page_flip is very accurate on
Avivo-based ASICs when vpos is negative.

Experiments were conducted on several ASIC generations ranging from RS690
to Cayman where the page flip was artificially timed to occur at a specific
vpos. With negative vpos, overriding update_pending always lead to
flickering.

The same experiment on RV380 and RV410 showed that update_pending is not
accurate with negative vpos. In most cases update_pending == 1 is returned
although the flip would complete before the start of the next frame.
Therefore I left the behaviour unchanged for pre-AVIVO ASICs for
performance reasons, although this may result in flickering in rare cases.

This change also makes the logic a little easier to understand.

466e69b8b0 drm: move pci bus master enable into driver.
The current enabling of bus mastering in the drm midlayer allows a large
race condition under kexec. When a kexec'ed kernel re-enables bus mastering
for the GPU, previously setup dma blocks may cause writes to random pieces
of memory. On radeon the writeback mechanism can cause these sorts of issues.

This patch doesn't fix the problem, but it moves the bus master enable under
the individual drivers control so they can move enabling it until later in
their load cycle and close the race.

Fix for radeon kms driver will be in a follow-up patch.

30388c6e48 drm/radeon/kms/dce3+: add support for hw i2c using atom
Starting with DCE3 hardware, atom contains a general purpose
ProcessI2cChannelTransaction similar to ProcessAuxChannelTransaction.

Add an implementation using the atom tables for DCE3+ hardware.

This should be a little less CPU intensive than bit banging and
may work better in certain cases.

Enable it by setting the radeon hw_i2c module parameter to 1.  E.g.,
radeon.hw_i2c=1
on the kernel command line in grub.

1849ecb22f drm/kms: Make i2c buses faster
A udelay value of 20 leads to an I2C bus running at only 25 kbps. I2C
devices can typically operate faster than this, 50 kbps should be fine
for all devices (and compliant devices can always stretch the clock if
needed.)

FWIW, the vast majority of framebuffer drivers set udelay to 10
already. So set it to 10 in DRM drivers too, this will make EDID block
reads faster. We might even lower the udelay value later if no problem
is reported.

52b53a0bf8 drm/radeon/kms/blit: fix blit copy for very large buffers
Evergreen and NI blit copy was broken if the buffer maps to a rectangle
whose one dimension is 16384 (max dimension allowed by these chips).
In the mainline kernel, the problem is exposed only when buffers are
very large (1G), but it's still a problem. The problem could be exposed
for smaller buffers if anyone modifies the algorithm for rectangle
construction in r600_blit_create_rect() (the reason why someone would
modify that algorithm is to tune the performance of buffer moves).

The root cause was in i2f() function which only operated on range between
0 and 16383. Fix this by extending the range of i2f() function to 0 to
32767.

While at it improve the function so that the range can be easily
extended in the future (if it becomes necessary), cleanup lines
over 80 characters, and replace in-line comments with one strategic
comment that explains the crux of the function.

Credits to michel@daenzer.net for pointing out the root cause of
the bug.

v2: Fix I2F_MAX_INPUT constant definition goof and warn only once
    if input argument is out of range. Edit the comment a little
    bit to avoid some linguistic confusion and make it look better
    in general.

The value of this register is transferred to the V_COUNTER register at the
beginning of vertical blank. V_COUNTER is the reference for VLINE waits and
goes from VIEWPORT_Y_START to VIEWPORT_Y_START+VIEWPORT_HEIGHT during scanout,
so if VIEWPORT_Y_START is not 0, V_COUNTER actually went backwards at the
beginning of vertical blank, and VLINE waits excluding the whole scanout area
could never finish (possibly only if VIEWPORT_Y_START is larger than the length
of vertical blank in scanlines). Setting DESKTOP_HEIGHT to the framebuffer
height should prevent this for any kind of VLINE wait.

211fa4fc4e drm/radeon: finish getting bios earlier
Return a number of bytes read in radeon_atrm_get_bios_chunk() and
properly check this value in radeon_atrm_get_bios().
If radeon_atrm_get_bios_chunk() read less bytes then were requested,
it means that it finished reading bios data.

Prior to this patch, condition in radeon_atrm_get_bios() was always
equivalent to "if (ATRM_BIOS_PAGE <= 0)", so it was always false,
thus radeon_atrm_get_bios() was trying to read past the bios data
wasting boot time.

On my lenovo ideapad u455 laptop this patch drops bios reading time
from ~5.5s to ~1.5s.

cc1f719429 drm: introduce drm_can_sleep and use in intel/radeon drivers. (v2)
So we have a few places where the drm drivers would like to sleep to
be nice to the system, mainly in the modesetting paths, but we also
have two cases were atomic modesetting must take place, panic writing
and kernel debugger. So provide a central inline to determine if a
sleep or delay should be used and use this in the intel and radeon drivers.

v2: drop intel_drv.h MSLEEP macro, nobody uses it.

Based on patch from Michel Dänzer <michel.daenzer@amd.com>

3df96909b7 radeon: Fix disabling PCI bus mastering on big endian hosts.
It would previously write basically random bits to PCI configuration space...
Not very surprising that the GPU tended to stop responding completely. The
resulting MCE even froze the whole machine sometimes.

Now resetting the GPU after a lockup has at least a fighting chance of
succeeding.

721604a15b drm/radeon: GPU virtual memory support v22
Virtual address space are per drm client (opener of /dev/drm).
Client are in charge of virtual address space, they need to
map bo into it by calling DRM_RADEON_GEM_VA ioctl.

First 16M of virtual address space is reserved by the kernel.

Once using 2 level page table we should be able to have a small
vram memory footprint for each pt (there would be one pt for all
gart, one for all vram and then one first level for each virtual
address space).

Plan include using the sub allocator for a common vm page table
area and using memcpy to copy vm page table in & out. Or use
a gart object and copy things in & out using dma.

v2: agd5f fixes:
- Add vram base offset for vram pages.  The GPU physical address of a
vram page is FB_OFFSET + page offset.  FB_OFFSET is 0 on discrete
cards and the physical bus address of the stolen memory on
integrated chips.
- VM_CONTEXT1_PROTECTION_FAULT_DEFAULT_ADDR covers all vmid's >= 1

v3: agd5f:
- integrate with the semaphore/multi-ring stuff

v4:
- rebase on top ttm dma & multi-ring stuff
- userspace is now in charge of the address space
- no more specific cs vm ioctl, instead cs ioctl has a new
  chunk

v5:
- properly handle mem == NULL case from move_notify callback
- fix the vm cleanup path

v6:
- fix update of page table to only happen on valid mem placement

v7:
- add tlb flush for each vm context
- add flags to define mapping property (readable, writeable, snooped)
- make ring id implicit from ib->fence->ring, up to each asic callback
  to then do ring specific scheduling if vm ib scheduling function

v8:
- add query for ib limit and kernel reserved virtual space
- rename vm->size to max_pfn (maximum number of page)
- update gem_va ioctl to also allow unmap operation
- bump kernel version to allow userspace to query for vm support

v9:
- rebuild page table only when bind and incrementaly depending
  on bo referenced by cs and that have been moved
- allow virtual address space to grow
- use sa allocator for vram page table
- return invalid when querying vm limit on non cayman GPU
- dump vm fault register on lockup

v10: agd5f:
- Move the vm schedule_ib callback to a standalone function, remove
  the callback and use the existing ib_execute callback for VM IBs.

v11:
- rebase on top of lastest Linus

v12: agd5f:
- remove spurious backslash
- set IB vm_id to 0 in radeon_ib_get()

v13: agd5f:
- fix handling of RADEON_CHUNK_ID_FLAGS

v14:
- fix va destruction
- fix suspend resume
- forbid bo to have several different va in same vm

v15:
- rebase

v16:
- cleanup left over of vm init/fini

v17: agd5f:
- cs checker

v18: agd5f:
- reworks the CS ioctl to better support multiple rings and
VM.  Rather than adding a new chunk id for VM, just re-use the
IB chunk id and add a new flags for VM mode.  Also define additional
dwords for the flags chunk id to define the what ring we want to use
(gfx, compute, uvd, etc.) and the priority.

v19:
- fix cs fini in weird case of no ib
- semi working flush fix for ni
- rebase on top of sa allocator changes

v20: agd5f:
- further CS ioctl cleanups from Christian's comments

v21: agd5f:
- integrate CS checker improvements

v22: agd5f:
- final cleanups for release, only allow VM CS on cayman

If the bpc is set from the connector is 0, we then use it later to adjust
in a special case the HDMI pixel clock, however if the bpc is 0, we end up
passing a 0 pixel clock into the code.

I'm not sure if this is the correct answer or if we should avoid the HDMI
clock adjustment for 0 values.

30eb77f4e6 drm/radeon: precompute fence cpu/gpu addr once v3
Add a start fence driver helper function which will be call
once for each ring and will compute cpu/gpu addr for fence
depending on wether to use wb buffer or scratch reg.

This patch replace initialize fence driver separately which
was broken in regard of GPU lockup. The fence list for created,
emited, signaled must be initialize once and only from the
asic init callback not from the startup call back which is
call from the gpu reset.

v2: With this in place we no longer need to know the number of
    rings in fence_driver_init, also writing to the scratch reg
    before knowing its offset is a bad idea.
