Egbert Eich 0829184711 drm/radeon: Don't destroy I2C Bus Rec in radeon_ext_tmds_enc_destroy().
radeon_i2c_fini() walks thru the list of I2C bus recs rdev->i2c_bus[]
to destroy each of them.
radeon_ext_tmds_enc_destroy() however also has code to destroy it's
associated I2C bus rec which has been obtained by radeon_i2c_lookup()
and is therefore also in the i2c_bus[] list.
This causes a double free resulting in a kernel panic when unloading
the radeon driver.
Removing destroy code from radeon_ext_tmds_enc_destroy() fixes this
problem.

Alex Deucher c1a7ca0de3 drm/radeon/cayman: set VM max pfn at MC init
No need to emit them at VM flush as we no longer use
variable sized page tables now that we support 2 level
page tables.  This matches the behavior of SI (which
does not support variable sized page tables).

Christian König 90a51a3292 drm/radeon: allocate page tables on demand v4
Based on Dmitries work, but splitting the code into page
directory and page table handling makes it far more
readable and (hopefully) more reliable.

Allocations of page tables are made from the SA on demand,
that should still work fine since all page tables are of
the same size.

Also using the fact that allocations from the SA are mostly
continuously (except for end of buffer wraps and under very
high memory pressure) to group updates send to the chipset
specific code into larger chunks.

v3: mostly a rewrite of Dmitries previous patch.

Linus Torvalds 612a9aab56 Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm merge (part 1) from Dave Airlie:
 "So first of all my tree and uapi stuff has a conflict mess, its my
  fault as the nouveau stuff didn't hit -next as were trying to rebase
  regressions out of it before we merged.

  Highlights:
   - SH mobile modesetting driver and associated helpers
   - some DRM core documentation
   - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write
     combined pte writing, ilk rc6 support,
   - nouveau: major driver rework into a hw core driver, makes features
     like SLI a lot saner to implement,
   - psb: add eDP/DP support for Cedarview
   - radeon: 2 layer page tables, async VM pte updates, better PLL
     selection for > 2 screens, better ACPI interactions

  The rest is general grab bag of fixes.

  So why part 1? well I have the exynos pull req which came in a bit
  late but was waiting for me to do something they shouldn't have and it
  looks fairly safe, and David Howells has some more header cleanups
  he'd like me to pull, that seem like a good idea, but I'd like to get
  this merge out of the way so -next dosen't get blocked."

Tons of conflicts mostly due to silly include line changes, but mostly
mindless.  A few other small semantic conflicts too, noted from Dave's
pre-merged branch.

Merge tag 'uapi-prep-20121002' of git://git.infradead.org/users/dhowells/linux-headers

Pull preparatory patches for user API disintegration from David Howells:
 "The patches herein prepare for the extraction of the Userspace API
  bits from the various header files named in the Kbuild files.

  New subdirectories are created under either include/uapi/ or
  arch/x/include/uapi/ that correspond to the subdirectory containing
  that file under include/ or arch/x/include/.

  The new subdirs under the uapi/ directory are populated with Kbuild
  files that mostly do nothing at this time.  Further patches will
  disintegrate the headers in each original directory and fill in the
  Kbuild files as they do it.

  These patches also:

   (1) fix up #inclusions of "foo.h" rather than <foo.h>.

   (2) Remove some redundant #includes from the DRM code.

   (3) Make the kernel build infrastructure handle Kbuild files both in
       the old places and the new UAPI place that both specify headers
       to be exported.

   (4) Fix some kernel tools that #include kernel headers during their
       build.

  I have compile tested this with allyesconfig against x86_64,
  allmodconfig against i386 and a scattering of additional defconfigs of
  other arches.  Prepared for main script

"The big changes for 3.7 include:

- 2 level VM page table support.  Saves memory compared to 1 level
  page tables.
- Reworked PLL handing in the display code allows lots more
  combinations of monitors to work, including more than two

  This also allows us to power down extra PLLs when we can

Remove redundant #inclusions of core DRM UAPI headers (drm.h, drm_mode.h and

patch.

Without this patch and the patch to make include the UAPI headers from the core
headers, after the UAPI split, the DRM C sources cannot find these UAPI headers
because the DRM code relies on specific -I flags to make #include "..."  work
on headers in include/drm/ - but that does not work after the UAPI split without
adding more -I flags.

Linus Torvalds 033d9959ed Merge branch 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq
Pull workqueue changes from Tejun Heo:
 "This is workqueue updates for v3.7-rc1.  A lot of activities this
  round including considerable API and behavior cleanups.

   * delayed_work combines a timer and a work item.  The handling of the
     timer part has always been a bit clunky leading to confusing
     cancelation API with weird corner-case behaviors.  delayed_work is
     updated to use new IRQ safe timer and cancelation now works as
     expected.

   * Another deficiency of delayed_work was lack of the counterpart of
     mod_timer() which led to cancel+queue combinations or open-coded
     timer+work usages.  mod_delayed_work[_on]() are added.

     These two delayed_work changes make delayed_work provide interface
     and behave like timer which is executed with process context.

   * A work item could be executed concurrently on multiple CPUs, which
     is rather unintuitive and made flush_work() behavior confusing and
     half-broken under certain circumstances.  This problem doesn't
     exist for non-reentrant workqueues.  While non-reentrancy check
     isn't free, the overhead is incurred only when a work item bounces
     across different CPUs and even in simulated pathological scenario
     the overhead isn't too high.

     All workqueues are made non-reentrant.  This removes the
     distinction between flush_[delayed_]work() and
     flush_[delayed_]_work_sync().  The former is now as strong as the
     latter and the specified work item is guaranteed to have finished
     execution of any previous queueing on return.

   * In addition to the various bug fixes, Lai redid and simplified CPU
     hotplug handling significantly.

   * Joonsoo introduced system_highpri_wq and used it during CPU
     hotplug.

  There are two merge commits - one to pull in IRQ safe timer from
  tip/timers/core and the other to pull in CPU hotplug fixes from
  wq/for-3.6-fixes as Lai's hotplug restructuring depended on them."

Fixed a number of trivial conflicts, but the more interesting conflicts
were silent ones where the deprecated interfaces had been used by new
code in the merge window, and thus didn't cause any real data conflicts.

Tejun pointed out a few of them, I fixed a couple more.

Dmitry Cherkasov fa87e62d35 drm/radeon: add 2-level VM pagetables support v9
PDE/PTE update code uses CP ring for memory writes.
All page table entries are preallocated for now in alloc_pt().

It is made as whole because it's hard to divide it to several patches
that compile and doesn't break anything being applied separately.

Tested on cayman card.

v2: rebased on top of "refactor set_page chipset interface v3",
    code cleanups

v3: switched offsets calc macros to inline funcs where possible,
    remove pd_addr from radeon_vm, switched RADEON_BLOCK_SIZE define,
    to 9 (and PTE_COUNT to 1 << BLOCK_SIZE)

v4 (ck): move "incr" documentation to previous patch, cleanup and
         document RADEON_VM_* constants, change commit message to
         our usual format, simplify patch allot by removing
         everything current not necessary, disable SI workaround.

v5: (agd5f): Fix typo in tables_size calculation in
             radeon_vm_alloc_pt().  Second line should have been
             '+=' rather than '='.

v6: fix npdes calculation. In scenario when pfns to be mapped overlap
two PDE spans:

   +-----------+-------------+
   | PDE span  | PDE span    |
   +-----------+----+--------+
          |         |
          +---------+
          | pfns    |
          +---------+

the following npdes calculation gives incorrect result:

npdes = (nptes >> RADEON_VM_BLOCK_SIZE) + 1;

For the case above picture it should give npdes = 2, but gives one.

This patch corrects it by rounding last pfn up to 512 border,
first - down to 512 border and then subtracting and dividing by 512.

v7: Make npde calculation clearer, fix ndw calculation.

v8: (agd5f): reserve enough for 2 full VM PTs, add some
             additional comments.

v9: fix typo in npde calculation

Alex Deucher 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.

Alex Deucher 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.

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.

We use __fls() to find the most significant bit.  Using that, the

conversion to the full 32 bits in a branchless way.

The routine is now exact up to 2^24.  Above that, we truncate which
is equivalent to rounding towards zero.

Simon Kitching 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)

Christian König 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.

Power gating is per crtc pair, but the powergating registers
should be called individually.  The hw handles power up/down
properly.  The pair is powered up if either crtc in the pair
is powered up and the pair is not powered down until both

programming and should save additional power as the previous

Marek Olšák fcdeefe4df drm/radeon: fix checking of MSAA renderbuffers on r600-r700
The MSAA checking was mostly unimplemented on r600-r700. The userspace
submits GPU commands and the kernel driver computes how much memory
the GPU will access and checks if it's all within buffer bounds the
userspace allocated. This patch fixes the computations of the size of
MSAA surfaces in memory.

Jerome Glisse 81ee8fb6b5 drm/radeon: do not reenable crtc after moving vram start address
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.

This patch should also fix :

Ilija Hadzic 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:

Christian König c6105f249a drm/radeon: remove vm_manager start/suspend
Just restore the page table instead. Addressing three
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
   unstable, creating an unrecoverable lockup

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

Alex Deucher 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.

 - Which just leaves a bunch of bugs about new modelines that don't work.

2. radeon_irq_set sometimes wasn't called with lock

   time.

3. The pm.gui_idle variable was assuming that the 3D

Jerome Glisse 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.

Alex Deucher 416a2bd274 drm/radeon: fixup tiling group size and backendmap on r6xx-r9xx (v4)
Tiling group size is always 256bits on r6xx/r7xx/r8xx/9xx. Also fix and
simplify render backend map. This now properly sets up the backend map
on r6xx-9xx which should improve 3D performance.

Vadim benchmarked also:
Some benchmarks on juniper (5750), fullscreen 1920x1080,
first result - kernel 3.4.0+ (fb21affa), second - with these patches:

Lightsmark:   91 fps => 123 fps    +35%
Doom3:        74 fps => 101 fps    +36%

Linus Torvalds f2fde3a65e Merge branch 'drm-core-next' of git://people.freedesktop.org/~airlied/linux
Pull main drm updates from Dave Airlie:
 "This is the main merge window request for the drm.

  It's big, but jam packed will lots of features and of course 0
  regressions.  (okay maybe there'll be one).

  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
  are also unblocked."

All radeon_gem_init() does is initialize the gem objects
list.  radeon_device.c does this explicitly.  r600+ calls
radeon_gem_init() so the list gets initialized twice.  Older
asics don't call it at all and rely on the the init in
radeon_device.c.  Just call radeon_gem_init() in radeon_device.c
and remove the explicit calls from all the newer asics.

All asics call radeon_gem_fini() in their fini pathes.  That
could possibly be cleaned up too.
