57b35e29cf drm/radeon: work around KMS modeset limitations in PLL allocation (v2)
Since the current KMS API sets the mode independantly on
each crtc, we may end up with resource conflicts.  The PLL
allocation is one of those cases.  In the following example
we have 3 crtcs in use driving 2 DVI connectors and 1 DP
connector.  On the initial kernel modeset for fbdev, the
display topology ends up as follows:

crtc0 -> DP-0
crtc1 -> DVI-0
crtc2 -> DVI-1

Because this is the first modeset, all of the PLLs are
available as none have been assigned.  So we end up with
the following:

crtc0 uses DCPLL
crtc1 uses PPLL2
crtc2 uses PPLL1

When X starts, it assigns a different topology:

crtc0 -> DVI-0
crtc1 -> DP-0
crtc2 -> DVI-1

However, since the KMS API is per crtc, we set the mode on each
crtc independantly.  When it comes time to set the mode on crtc0,
the topology for crtc1 and crtc2 are still intact.  crtc1 and
crtc2 are already assigned PPLL2 and PPLL1 so when it comes time
to set the mode on crtc0, crtc1 and crtc2 have not been torn down
yet, so there appears to be no PLLs available.  In reality, we
are reconfiguring the entire display topology, however, since
each crtc is handled independantly, we don't know that in the
driver at each crtc mode set time.

This patch checks to see if the same connector is being driven by
another crtc, and if so, uses the PLL already associated with it.

v2: store connector in the radeon crtc struct, simplify checking.

Merge tag 'v3.6-rc7' into drm-intel-next-queued

Manual backmerge of -rc7 to resolve a silent conflict leading to
compile failure in drivers/gpu/drm/i915/intel_hdmi.c.

This is due to the bugfix in -rc7:

commit b98b601672
Author: Wang Xingchao <xingchao.wang@intel.com>
Date:   Thu Sep 13 07:43:22 2012 +0800

    drm/i915: HDMI - Clear Audio Enable bit for Hot Plug

Since this code moved around a lot in -next git put that snippet at
the wrong spot. I've tried to fix this by making the conflict explicit
by merging a version for next with:

commit 3cce574f01
Author: Wang Xingchao <xingchao.wang@intel.com>
Date:   Thu Sep 13 11:19:00 2012 +0800

    drm/i915: HDMI - Clear Audio Enable bit for Hot Plug unconditionally

But that failed to solve the entire problem. To avoid pushing out
further -nightly branch to our QA where this is broken, do the
backmerge and manually add the stuff git adds to -next from the patch
in -fixes.

Note that this doesn't show up in git's merge diff (and hence is also
not handled by git rerere), which adds to the reasons why I'd like to
fix this with a verbose backmerge. The git merge diff only shows a
bunch of trivial conflicts of the "code changed in lines next to each
another" kind.

2f454cf126 drm/radeon: allow PPLL sharing on non-DP displays
If several non-DP displays use the same pixel clock
we can use the same PPLL for all of them.  If all
relevant displays have the same pixel clock, this
allows the driver to:
- use fewer PPLLs which saves power
- support more than two non-DP displays on DCE4+

The current drm modesetting infrastructure doesn't
really provide a good framework for validating combinations
that work or won't work, so it's possible you could go from
a working configuration to a non-working one by changing the
mode a one of the displays.  However, there this is better
than what was there before.

f3dd8508d4 drm/radeon: rework pll selection (v4)
For DP we can use the same PPLL for all active DP
encoders.  Take advantage of that to prevent cases
where we may end up sharing a PPLL between DP and
non-DP which won't work.  Also clean up the code
a bit.

v2: - fix missing pll_id assignment in crtc init
v3: - fix DP PPLL check
    - document functions
    - break in main encoder search loop after matching.
      no need to keep checking additional encoders.
v4: - same as v3, but re-apply to drm-next as the corner
      cases are fixed properly in subsequent patches.

16c58081eb drm/radeon: Prevent leak of scratch register on resume from suspend
Cards typically have 5-7 scratch registers; one of these is reserved for
rdev->rptr_save_reg. Unfortunately the reservation is done in function
r100_cp_init, which is called by all drivers except r600 - and this
function is also invoked on resume from suspend. After several resumes,
no scratch registers are free and graphics acceleration is disabled.

Dmesg then reports either:
   *ERROR* radeon: cp failed to get scratch reg (-22).
   *ERROR* radeon: cp isn't working(-22).
   radeon 0000:01:00.0: failed initializing CP (-22).
or:
   *ERROR* radeon: failed to get scratch reg (-22).
   *ERROR* radeon: failed testing IB on GFX ring (-22).
   *ERROR* ib ring test failed (-22).

The chain of calls on boot for all except r600 is:
radeon_init -> ... -> (rXXX_init) -> rXXX_startup -> r100_cp_init

The chain of calls on resume for all except r600 is:
rXXX_resume -> rXXX_startup -> r100_cp_init.

R600 correctly allocates rptr_save_reg in r600_init (ie once only, not
in resume). However moving the code into the init functions for all
drivers means touching 4 drivers. So instead, this patch just adds a
test in r100_cp_init to avoid reallocating on resume. As the rdev
structure is allocated via kzalloc in radeon_driver_load_kms, and zero
is not a valid registerid, zero safely implies not-yet-allocated.

This issue appears to have been introduced in c7eff978 (3.6.0-rcN)

f492c171a3 drm/radeon: make 64bit fences more robust v3
Only increase the higher 32bits if we really detect a wrap around.

v2: instead of increasing the higher 32bits just use the higher
    32bits from the last emitted fence.
v3: also use last emitted fence value as upper limit.

The intention of this patch is to make fences as robust as
they where before introducing 64bit fences. This is
necessary because on older systems it looks like the fence
value gets corrupted on initialization.

It seems we can not update the crtc scanout address. After disabling
crtc, update to base address do not take effect after crtc being
reenable leading to at least frame being scanout from the old crtc
base address. Disabling crtc display request lead to same behavior.

So after changing the vram address if we don't keep crtc disabled
we will have the GPU trying to read some random system memory address
with some iommu this will broke the crtc engine and will lead to
broken display and iommu error message.

So to avoid this, disable crtc. For flicker less boot we will need
to avoid moving the vram start address.

949c4a34af drm: track dev_mapping in more robust and flexible way
Setting dev_mapping (pointer to the address_space structure
used for memory mappings) to the address_space of the first
opener's inode and then failing if other openers come in
through a different inode has a few restrictions that are
eliminated by this patch.

If we already have valid dev_mapping and we spot an opener
with different i_node, we force its i_mapping pointer to the
already established address_space structure (first opener's
inode). This will make all mappings from drm device hang off
the same address_space object.

Some benefits (things that now work and didn't work
before) of this patch are:

 * user space can mknod and use any number of device
   nodes and they will all work fine as long as the major
   device number is that of the drm module.
 * user space can even remove the first opener's device
   nodes and mknod the new one and the applications and
   windowing system will still work.
 * GPU drivers can safely assume that dev->dev_mapping is
   correct address_space and just blindly copy it
   into their (private) bdev.dev_mapping

For reference, some discussion that lead to this patch can
be found here:

This could previously fail if either of the enabled displays was using a

of the cursor was (supposed to be) visible at the right edge of that display.

The solution is to move the cursor one pixel to the left in that case.

problem with this change:

1. Calling vm_manager_suspend in the suspend path is
   problematic cause it wants to wait for the VM use
   to end, which in case of a lockup never happens.

2. In case of a locked up memory controller
   unbinding the VM seems to make it even more

3. If we want to backup/restore the leftover ring

c21b328ea8 drm/radeon: fix VM page table setup on SI
Cayman and trinity allow for variable sized VM page
tables, but SI requires that all page tables be the
same size.  The current code assumes variablely sized
VM page tables so SI may end up with part of each page
table overlapping with other memory which could end
up being interpreted by the VM hw as garbage.

Change the code to better accomodate SI.  Allocate enough
space for at least 2 full page tables and always set
last_pfn to max_pfn on SI so each VM is backed by a full
page table.  This limits us to only 2 VMs active at any
given time on SI.  This will be rectified and the code can
be reunified once we move to two level page tables.

 Wrt regressions QA reported quite a few this time around.
 - The piglit/kernel-test fallout all has patches that are just awaiting
   review and merging into the next -next cycle.
 - Which just leaves a bunch of bugs about new modelines that don't work.
   It looks like these are all due to the new 16:9/16:10 modes in 3.5
   (yeah, only in this manual testing cycle did the git branch used by QA
   contain a backmerge of mainline with these patches).  Although I haven't
   yet confirmed this by letting our QA test the revert of that series.
 - Wrt bugs in general I'm trying to fight down some of our long-standing
   backlight issues (not regressions), but this seems to be a game of
   "you move, you lose" ... :("

Dropped merge bits since this had an -rc4 merge in it to fix some ugly

fb98257a9d drm/radeon: apply Murphy's law to the kms irq code v3
1. It is really dangerous to have more than one
   spinlock protecting the same information.

2. radeon_irq_set sometimes wasn't called with lock
   protection, so it can happen that more than one
   CPU would tamper with the irq regs at the same
   time.

3. The pm.gui_idle variable was assuming that the 3D
   engine wasn't becoming idle between testing the
   register and setting the variable. So just remove
   it and test the register directly.

v2: Also handle the hpd irq code the same way.
v3: Rename hpd parameter for clarification.

d26098759c drm/radeon: fix tiling and command stream checking on evergreen v3
Fix regresson since the introduction of command stream checking on
evergreen (thread referenced below). Issue is cause by ddx allocating
bo with formula width*height*bpp while programming the GPU command
stream with ALIGN(height, 8). In some case (where page alignment does
not hide the extra size bo should be according to height alignment)
the kernel will reject the command stream.

This patch reprogram the command stream to slice - 1 (slice is
a derivative value from height) which avoid rejecting the command
stream while keeping the value of command stream checking from a
security point of view.

This patch also fix wrong computation of layer size for 2D tiled
surface. Which should fix issue when 2D color tiling is enabled.
This dump the radeon KMS_DRIVER_MINOR so userspace can know if
they are on a fixed kernel or not.

 "This is the main merge window request for the drm.

  Highlights:

   - new KMS drivers for server GPU chipsets: ast, mgag200 and cirrus
     (qemu only).  These drivers use the generic modesetting drivers.

   - initial prime/dma-buf support for i915, nouveau, radeon, udl and
     exynos

   - switcheroo audio support: so GPUs with HDMI can turn off the sound
     driver without crashing stuff.

   - There are some patches drifting outside drivers/gpu into x86 and
     EFI for better handling of multiple video adapters in Apple Macs,
     they've got correct acks except one trivial fixup.

   - Core:
	edid parser has better DMT and reduced blanking support,
	crtc properties,
	plane properties,

   - Drivers:
	exynos: add 2D core accel support, prime support, hdmi features
	intel: more Haswell support, initial Valleyview support, more
	    hdmi infoframe fixes, update MAINTAINERS for Daniel, lots of
	    cleanups and fixes
	radeon: more HDMI audio support, improved GPU lockup recovery
	    support, remove nested mutexes, less memory copying on PCIE, fix
	    bus master enable race (kexec), improved fence handling
	gma500: cleanups, 1080p support, acpi fixes
	nouveau: better nva3 memory reclocking, kepler accel (needs
	    external firmware rip), async buffer moves on nv84+ hw.

  I've some more dma-buf patches that rely on the dma-buf merge for vmap
  stuff, and I've a few fixes building up, but I'd decided I'd better
  get rid of the main pull sooner rather than later, so the audio guys

40f5cf9969 drm/radeon: add PRIME support (v2)
This adds prime->fd and fd->prime support to radeon.
It passes the sg object to ttm and then populates
the gart entries using it.

Compile tested only.

v2: stub kmap + use new helpers + add reimporting

129b78bfca ttm: add prime sharing support to TTM (v2)
This adds the ability for ttm common code to take an SG table
and use it as the backing for a slave TTM object.

The drivers can then populate their GTT tables using the SG object.

v2: make sure to setup VM for sg bos as well.
