Kleber Sacilotto de Souza 7e0e419637 radeon: use max_bus_speed to activate gen2 speeds
radeon currently uses a drm function to get the speed capabilities for
the bus, drm_pcie_get_speed_cap_mask. However, this is a non-standard
method of performing this detection and this patch changes it to use
the max_bus_speed attribute.

Alex Deucher 50a583f64b drm/radeon: narrow scope of Apple re-POST hack
This narrows the scope of the apple re-POST hack added in:
drm/radeon: re-POST the asic on Apple hardware when booted via EFI

That patch prevents UVD from working on macs when booted in EFI
mode.  The original patch fixed macbook2,1 systems which were
r5xx and hence have no UVD.  Limit the hack to those systems to
prevent UVD breakage on newer systems.

Newer asics have variable numbers of crtcs.  Use that

to check.  This avoids checking non-existent crtcs or

- Fix up the setcrtc semantics to unconditionally enable the outputs.
  Juding from git digging that has (kinda) always been the case and neatly

- jiffies_timeout + 1 patches from Imre. They partially fix spurious

  few patches more than strictly required since Imre is pushing for a

Jani Nikula 5a09ae9fd5 drm/i915: refactor VLV IOSF sideband accessors to use one helper
Both the intel_dpio_{read,write} and valleyview_{punit,nc}_{read,write}
use the IOSF sideband interface. They access the same registers and do
mostly the same stuff, but no shared code. There are even duplicate
register defines for the same registers. Both have locking, but the
former use dpio_lock and the latter rps.hw_lock. It's racy.

This patch refactors the sideband access to a single function that
expects dpio_lock to be held. The dpio_lock is only used for sideband
stuff, so it's a better match than rps.hw_lock for the purpose. The rps
stuff still needs rps.hw_lock, since it's used to protect more than just
the register access, so rps code will need to hold both locks.

Chris Wilson 2dc8aae06d drm/i915: Workaround incoherence with fence updates on Valleyview
In commit 25ff1195f8
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Thu Apr 4 21:31:03 2013 +0100

    drm/i915: Workaround incoherence between fences and LLC across multiple CPUs

we introduced an empirical workaround for memory corruption when using
fences from multiple CPUs. At the time, we did not have any results for
Valleyview, so the presumption was that it was limited to recent
generations using LLC. Now we have evidence that Valleyview also suffers
incoherence and requires a similar but different workaround. For
Valleyview, the wbinvd instruction is insufficient and we require the
serialising register write per-CPU. Conversely, that serialising
register write is not enough for SNB/IVB/HSW. To compromise and keep the
code relatively clean, employ both serialisation techniques in the same
workaround.

Paulo Zanoni 90a8864320 drm/i915: set FORCE_ARB_IDLE_PLANES workaround
Commit 1544d9d573 added a workaround
inside haswell_init_clock_gating and mentioned it is "a workaround for
early silicon revisions and should be removed later". This workaround
is documented in bit 31 of PRI_CTL. I asked Arthur and he mentioned
that setting FORCE_ARB_IDLE_PLANES replaces that workaround for the
newer machines. So use the new one.

Also notice that there's still another workaround for PRI_CTL that
involves WM_DBG, but it's not the one we're reverting. And notice that
we were previously setting WM_DBG_DISALLOW_MULTIPIPE_LP which disables
the LP watermarks when more than one pipe is used, and we really don't
want this because we need the LP watermarks if we want to reach deeper
PC states.

Tomi Valkeinen 591a0ac7f1 OMAPDSS: Fix crash with DT boot
When booting with DT, there's a crash when omapfb is probed. This is
caused by the fact that omapdss+DT is not yet supported, and thus
omapdss is not probed at all. On the other hand, omapfb is always
probed. When omapfb tries to use omapdss, there's a NULL pointer
dereference crash. The same error should most likely happen with omapdrm
and omap_vout also.

To fix this, add an "initialized" state to omapdss. When omapdss has
been probed, it's marked as initialized. omapfb, omapdrm and omap_vout
check this state when they are probed to see that omapdss is actually
there.

Imre Deak e3de42b684 drm/i915: force full modeset if the connector is in DPMS OFF mode
Currently the driver's assumed behavior for a modeset with an attached
FB is that the corresponding connector will be switched to DPMS ON mode
if it happened to be in DPMS OFF (or another power save mode). This
wasn't enforced though if only the FB changed, everything else (format,
connector etc.) remaining the same. In this case we only set the new FB
base and left the connector in the old power save mode.

Fix this by forcing a full modeset whenever there is an attached FB and
any affected connector is in a power save mode.

V_2: Run the test for encoders in power save mode outside the the
test for fb change: user space may have just disabled the encoders
but left everything else in place. Make sure the connector list is
not empty before running this test.

At DDX commit Chris mentioned the tendency we have of finding out more
PCI IDs only when users report. So Let's add all new reserved Haswell IDs.

This patch also fix GT3 names. I'no not sending in separated patche because
names are only in few comments and not in variable names.

Paulo Zanoni b2b877ffe3 drm/i915: make intel_ddi_get_cdclk_freq return values in KHz
With this, that 338 can finally become the correct 337500.

Due to the change we need to adjust the intel_dp_aux_ch function to
set the correct value, so adjust the division and also use
DIV_ROUND_CLOSEST instead of the old "round down" behavior because the
spec says the value "should be programmed to get as close as possible
to the ideal rate of 2MHz".

Quoting Paulo's follow-up to a question from Chris Wilson to explain
what exactly will change:

I use the 337500 value on the next patch, when setting the
ips_linetime value. The correct frequency is 337500, not 338000.

ips_linetime = DIV_ROUND_CLOSEST(mode->htotal * 1000 * 8,
intel_ddi_get_cdclk_freq);
For a mode with htotal of 2640 [0] we'll have: (i) (2640 * 1000 * 8) /
338000 = 62.48, resulting in 62 and (ii) (2640 * 1000 * 8) / 337500 =
62.57 resulting in 63.

For the case inside intel_dp.c:
Previously we were using 338. So with the old formula we were writing
338/2 = 169 to the register. And 337500 / 169 = 1997.04 (we use 337500
here because it's the real clock value). With the new value of
337500/2000 we'll have 168.75, which is 168 on the round-down case and
169 on the round-closest case. If we write 168 to the register, 337500
/ 168 = 2008.92, and 2008.92 is more distant from 2000 than 1997.04.
So with this patch we're changing the formula but still writing the
same correct value to the DP AUX register.

[0]: That's 1920x1080@50Hz on my DP monitor.

Paulo Zanoni 1011d8c437 drm/i915: remove intel_update_linetime_watermarks
The spec says the linetime watermarks must be programmed before
enabling any display low power watermarks, but we're currently
updating the linetime watermarks after we call intel_update_watermarks
(and only at crtc_mode_set, not at crtc_{enable,disable}). So IMHO the
best way guarantee the linetime watermarks will be updated before the
low power watermarks is inside the update_wm function, because it's
the function that enables low power watermarks. And since Haswell is
the only platform that has linetime watermarks, let's completely kill
the "intel_update_linetime_watermarks" abstraction and just use the
intel_update_watermarks abstraction by creating haswell_update_wm.

For now haswell_update_wm is still calling sandybridge_update_wm, but
in the future I plan to implement a function specific to Haswell.

v2: - Rename patch
    - Disable LP watermarks before changing linetime WMs (Chris)
    - Add a comment explaining that this is just temporary code.

Merge tag 'v3.10-rc2' into drm-intel-next-queued

Backmerge Linux 3.10-rc2 since the various (rather trivial) conflicts
grew a bit out of hand. intel_dp.c has the only real functional
conflict since the logic changed while dev_priv->edp.bpp was moved
around.

Also squash in a whitespace fixup from Ben Widawsky for
i915_gem_gtt.c, git seems to do something pretty strange in there
(which I don't fully understand tbh).

Linus Torvalds e51066824a Merge branch 'devm_no_resource_check' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull devm usage cleanup from Wolfram Sang:
 "Lately, I have been experimenting how to improve the devm interface to
  make writing device drivers easier and less error prone while also
  getting rid of its subtle issues.  I think it has more potential but
  still needs work and definately conistency, especiall in its usage.

  The first thing I come up with is a low hanging fruit regarding
  devm_ioremap_resouce().  This function already checks if the passed
  resource is valid and gives an error message if not.  So, we can
  remove similar checks from the drivers and get rid of a bit of code
  and a number of inconsistent error strings.

  This series only removes the unneeded check iff devm_ioremap_resource
  follows platform_get_resource directly.  The previous version tried to
  shuffle code if needed, too, what lead to an embarrasing bug.  It
  turned out to me that shuffling code for all cases found will make the
  automated script too complex, so I am unsure if an automated cleanup
  is the proper tool for this case.  Removing the easy stuff seems
  worthwhile to me, though.

  Despite various architectures and platform dependencies, I managed to
  compile test 45 out of 57 modified files locally using heuristics and
  defconfigs."

Dave Airlie a6ac1bc341 drm/qxl: fix ioport interactions for kernel submitted commands.
So qxl has ioports, but it really really really doesn't want you
to write to them twice, but if you write and get a signal before
the irq arrives to let you know its completed, you have to think
ahead and avoid writing another time.

However this works fine for update area where really multiple
writes aren't the end of the world, however with create primary
surface, you can't ever do multiple writes. So this stop internal
kernel writes from doing interruptible waits, because otherwise
we have no idea if this write is a new one or a continuation of
a previous one.

virtual hw sucks more than real hw.

This fixes lockups and VM crashes when resizing and starting/stopping
X.

Pfit state readout is a bit ugly on gen2/3 due to the intermingling

Christopher Harvey fb70a66908 drm/mgag200: Fix writes into MGA1064_PIX_CLK_CTL register
The original line,
  WREG_DAC(MGA1064_PIX_CLK_CTL_CLK_DIS, tmp);
wrote tmp into MGA1064_PIX_CLK_CTL_CLK_DIS, where
MGA1064_PIX_CLK_CTL_CLK_DIS is an offset into
MGA1064_PIX_CLK_CTL. Change the line to write properly into
MGA1064_PIX_CLK_CTL. There were other chunks of code nearby that use
the same pattern (but work correctly), so this patch updates them all
to use this new (slightly more efficient) write pattern. The WREG_DAC
macro was causing the DAC_INDEX register to be set to the same value
twice. WREG8(DAC_DATA, foo) takes advantage of the fact that DAC_INDEX
is already at the value we want.

It adds a new function gen7_enable_fbc to avoid getting

Daniel Vetter fec32900cc drm/i915: rip out TV-out lore ...
This seems to be an impressive piece of copy&pasta lore. I've
checked all docs and on most platforms these bits are all MBZ, with
the exception of the SDVO pixel multiplier on gen3. On gen4 that
moved to a special DPLL_MD registers.

No indication whatsoever that we actually need this for native
TV-out support. I suspect this started as a hack when we didn't
yet have proper pixel multiplier support in place for SDVO TV, but
then got stuck in a life of its own.

TV-out uses the same reference clock as everyone else. The only
difference seems to be in the slightly different CB tuning limit.

Note that PLL_REF_INPUT_TVCLKINBC is a reserved value on ilk+. Also
strictly speaking we don't support native TV-out on ilk+, hence all
that code is dead. But Bspec still contains some residual mentions of
native TV-out on some pch-split platforms, so I've figured it doesn't
hurt to keep the code around a bit longer (e.g. in the cb tune
function).

Jani Nikula bc5ead8c09 drm/i915: fix hotplug event bit tracking
commit 142e239849
Author: Egbert Eich <eich@suse.de>
Date:   Thu Apr 11 15:57:57 2013 +0200

    drm/i915: Add bit field to record which pins have received HPD events (v3)

added a bit field for hotplug event tracking. There ended up being three
different v3 of the patch: [1], [2], and [3]. Apparently [1] was the
correct one, but some frankenstein combination of the three got
committed, which reversed the logic for setting the hotplug bits and
misplaced a continue statement, skipping the hotplug irq storm handling
altogether.

This lead to broken hotplug detection, bisected to
commit 321a1b3026
Author: Egbert Eich <eich@suse.de>
Date:   Thu Apr 11 16:00:26 2013 +0200

    drm/i915: Only reprobe display on encoder which has received an HPD event (v2)

which uses the incorrectly set hotplug event bits.

Fix the mess.

Ben Widawsky c4ae25ecdf Revert "drm/i915: Calculate correct stolen size for GEN7+"
This reverts commit 03752f5b7b.

This revert requires a bit of explanation on how I understand things
work. Internally the architects/designers decide how the stolen encoding
works. We put it in a doc. BIOS writers take these docs and implement
it. Driver writers read the doc too, and read the value left by the BIOS
writers, and then we make magic.

The failing here is that in the docs we had[1] contained two different
definitions for this register for Gen7. (We have both a PCI register,
and an MMIO, and each of these were different). At the time [2] of
03752f5, we asked the architects what the correct value should be; but
that doesn't match the reality (BIOS) unfortunately.

So on all machines I can get my hands on, this revert is the right thing
to do. I've also worked with the product group to confirm that they
agree this revert is what we should do. People using HW made my "people"
who both write their own BIOS, and have access to our docs (Apple?).
Investigations are still ongoing about whether we need to add a list
of machines needing special handling, but this patch should be the
right thing for pretty much everyone.

[1] The docs are still wrong on this one. Now instead of two registers with
two definitions, we have one register with BOTH definitions, progress?
[2] The open source PRMs have the "wrong" definitions in chapter Volume
1 part6, section 1.1.12.

This digging was inspired by Paulo.

Chris Wilson 112522f678 drm/i915: put context upon switching
In order to be notified of when the context and all of its associated
objects is idle (for if the context maps to a ppgtt) we need a callback
from the retire handler. We can arrange this by using the kref_get/put
of the context for request tracking and by inserting a request to
demarque the switch away from the old context.

Daniel Vetter 21a8e6a485 drm/i915: don't setup hdmi for port D edp in ddi_init
dp_init_connector adjusts the encoder type if it is a eDP panel. Use
that to decide whether we should set up a hdmi connector or not.

To do so reorder the hdmi connector setup sequence in ddi_init a bit.

Imre Deak 3ab9c63705 drm/i915: hsw: fix link training for eDP on port-A
According to BSpec the link training sequence for eDP on HSW port-A
should be as follows:

1. link training: clock recovery
2. link training: equalization
3. link training: set idle transmission mode
4. display pipe enable
5. link training: disable (set normal mode)

Contrary to this at the moment we don't do step 3. and we do step 5.
before step 4. Fix this by setting idle transmission mode for eDP at
the end of intel_dp_complete_link_train and adding a new
intel_dp_stop_link_training function to disable link training. With
these changes we'll end up with the following functions corresponding
to the above steps:

intel_dp_start_link_train    -> step 1.
intel_dp_complete_link_train -> step 2., step 3.
intel_dp_stop_link_train     -> step 5.

For port-A we'll call intel_dp_stop_link_train only after enabling the
pipe, for everything else we'll call it right after
intel_dp_complete_link_train to preserve the current behavior.

Tested on HSW/HSW-ULT.

In v2:
- Due to a HW issue we must set idle transmission mode for port-A too
  before enabling the pipe. Thanks for Arthur Runyan for explaining
  this.
- Update the patch subject to make it clear that it's an eDP fix, DP is
  not affected.

v3:
- rename intel_dp_link_train() to intel_dp_set_link_train(), use 'val'
  instead 'l' as var name. (Paulo)

It's an ugly hack for a Haswell SDV platform where the vbt doesn't

Linus Torvalds 99bece775f Merge branch 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c changes from Wolfram Sang:

 - an arbitration driver.  While the driver is quite simple, it caused
   discussion if we need additional arbitration on top of the one
   specified in the I2C standard.  Conclusion is that I accept a few
   generic mechanisms, but not very specific ones.

 - the core lost the detach_adapter() call.  It has no users anymore and
   was in the way for other cleanups.  attach_adapter() is sadly still
   there since there are users waiting to be converted.

 - the core gained a bus recovery infrastructure.  I2C defines a way to
   recover if the data line is stalled.  This mechanism is now in the
   core and drivers can now pass some data to make use of it.

 - bigger driver cleanups for designware, s3c2410

 - removing superfluous refcounting from drivers

 - removing Ben Dooks as second maintainer due to inactivity.  Thanks
   for all your work so far, Ben!

 - bugfixes, feature additions, devicetree fixups, simplifications...

Use remove_proc_subtree() rather than remove_proc_entry() to remove a
minor-specific drm proc directory and all its children.

Things could theoretically be improved by storing the drm_minor pointer in the
minor-specific dir proc_dir_entry struct data and then scrapping the list of
proc files - but that's shared with the debugfs interface where you can't do
that, so I don't see an easy way of doing it.

Also, use "%u" not "%d" to render the value and use a 12-byte buffer in which

Dave Airlie 33896bf320 udl: bind the framebuffer to the correct device.
This just moves the fb sysfs node beside the drm sysfs node which
I fixed before.

just noticed it in passing.

Imre Deak 011c2282c7 drm: prime: fix refcounting on the dmabuf import error path
In commit be8a42ae60 we inroduced a refcount problem, where on the
drm_gem_prime_fd_to_handle() error path we'll call dma_buf_put() for
self imported dma buffers.

Fix this by taking a reference on the dma buffer in the .gem_import
hook instead of assuming the caller had taken one. Besides fixing the
bug this is also more logical.

Dave Airlie 219b47339c drm/prime: keep a reference from the handle to exported dma-buf (v6)
Currently we have a problem with this:
1. i915: create gem object
2. i915: export gem object to prime
3. radeon: import gem object
4. close prime fd
5. radeon: unref object
6. i915: unref object

i915 has an imported object reference in its file priv, that isn't
cleaned up properly until fd close. The reference gets added at step 2,
but at step 6 we don't have enough info to clean it up.

The solution is to take a reference on the dma-buf when we export it,
and drop the reference when the gem handle goes away.

So when we export a dma_buf from a gem object, we keep track of it
with the handle, we take a reference to the dma_buf. When we close
the handle (i.e. userspace is finished with the buffer), we drop
the reference to the dma_buf, and it gets collected.

This patch isn't meant to fix any other problem or bikesheds, and it doesn't
fix any races with other scenarios.

v1.1: move export symbol line back up.

v2: okay I had to do a bit more, as the first patch showed a leak
on one of my tests, that I found using the dma-buf debugfs support,
the problem case is exporting a buffer twice with the same handle,
we'd add another export handle for it unnecessarily, however
we now fail if we try to export the same object with a different gem handle,
however I'm not sure if that is a case I want to support, and I've
gotten the code to WARN_ON if we hit something like that.

v2.1: rebase this patch, write better commit msg.
v3: cleanup error handling, track import vs export in linked list,
these two patches were separate previously, but seem to work better
like this.
v4: danvet is correct, this code is no longer useful, since the buffer
better exist, so remove it.
v5: always take a reference to the dma buf object, import or export.
(Imre Deak contributed this originally)
v6: square the circle, remove import vs export tracking now
that there is no difference

Mika Kuoppala dce3271b1e drm/i915: reference count for i915_hw_contexts
Enabling PPGTT and also the need to track which context was guilty of
gpu hang (arb robustness enabling) have put pressure for struct i915_hw_context
to be more than just a placeholder for hw context state.

In order to track object lifetime properly in a multi peer usage, add reference
counting for i915_hw_context.

v2: track i915_hw_context pointers instead of using ctx_ids
(from Chris Wilson)

v3 (Ben): Get rid of do_release() and handle refcounting more compactly.
(recommended by Chis)

v4: kref_* put inside static inlines (Daniel Vetter)
remove code duplication on freeing context (Chris Wilson)

v5: idr_remove and ctx->file_priv = NULL in destroy ioctl (Chris)
This actually will cause a problem if one destroys a context and later
refers to the idea of the context (multiple contexts may have the same
id, but only 1 will exist in the idr).

v6: Strip out the request related stuff. Reworded commit message.
Got rid of do_destroy and introduced i915_gem_context_release_handle,
suggested by Chris Wilson.

v7: idr_remove can't be called inside idr_for_each (Chris Wilson)
