Alex Deucher 8a227555a8 drm/radeon/kms: enable UVD as needed (v9)
When using UVD, the driver must switch to a special UVD power
state.  In the CS ioctl, switch to the power state and schedule
work to change the power state back, when the work comes up,
check if uvd is still busy and if not, switch back to the user
state, otherwise, reschedule the work.

Note:  We really need some better way to decide when to
switch out of the uvd power state.  Switching power states
while playback is active make uvd angry.

V2: fix locking.

V3: switch from timer to delayed work

    1 second and rearm timeout on activity

Dave Airlie 4c813d4d75 drm: add hotspot support for cursors.
So it looks like for virtual hw cursors on QXL we need to inform
the "hw" device what the cursor hotspot parameters are. This
makes sense if you think the host has to draw the cursor and interpret
clicks from it. However the current modesetting interface doesn't support
passing the hotspot information from userspace.

This implements a new cursor ioctl, that takes the hotspot info as well,
userspace can try calling the new interface and if it gets -ENOSYS it means
its on an older kernel and can just fallback.

Alex Deucher 963e81f9e0 drm/radeon/cik: Add support for compute queues (v4)
On CIK, the compute rings work slightly differently than
on previous asics, however the basic concepts are the same.

The main differences:
- New MEC engines for compute queues
- Multiple queues per MEC:
  - CI/KB: 1 MEC, 4 pipes per MEC, 8 queues per pipe = 32 queues
  -    KV: 2 MEC, 4 pipes per MEC, 8 queues per pipe = 64 queues
- Queues can be allocated and scheduled by another queue
- New doorbell aperture allows you to assign space in the aperture
  for the wptr which allows for userspace access to queues

Daniel Vetter 160954b7bc drm: kms_helper: don't lose hotplug event
There's a race window (small for hpd, 10s large for polled outputs)
where userspace could sneak in with an unrelated connnector probe
ioctl call and eat the hotplug event (since neither the hpd nor the
poll code see a state change).

To avoid this, check whether the connector state changes in all other
->detect calls (in the current helper code that's only probe_single)
and if that's the case, fire off a hotplug event. Note that we can't
directly call the hotplug event handler, since that expects that no
locks are held (due to reentrancy with the fb code to update the kms
console).

Also, this requires that drivers using the probe_single helper
function set up the poll work. All current drivers do that already,
and with the reworked hpd handling there'll be no downside to
unconditionally setting up the poll work any more.

(same regs and bits). We could share the SI variants, and
I may yet do that, but I figured I would add CIK specific

V2: add documentation, minor fixes.
V3: integrate vram offset fixes for APUs
V4: enable 2 level VM PTs
V5: index SH_MEM_* regs properly
V6: add ib_parse()

non-privileged IBs, if the CP encounters an illegal

an interrupt.  The CP needs to be reset to continue.  For now

Daniel Vetter 5cef29aa52 drm: fix fb leak in setcrtc
Drivers are allowed (actually have to) disable unrelated crtcs in
their ->set_config callback (when we steal all the connectors from
that crtc). If they do that they'll clear crtc->fb to NULL.

Which results in a refcount leak, since the drm core is keeping track
of that reference.

To fix this track the old fb of all crtcs and adjust references for
all of them. Of course, since we only hold an additional reference for
the fb for the current crtc we need to increase refcounts before we
drop the old one.

This approach has the benefit that it inches us a bit closer to an
atomic modeset world, where we want to update the config of all crtcs
in one step.

This regression has been introduce in the framebuffer refcount
conversion, specifically in

Daniel Vetter cc85e1217f drm: check that ->set_config properly updates the fb
Historically drm lacked fb refcounting, so the updating of crtc->fb
was done by the lower levels at a point convenient to get their own
refcounting (e.g. refcounts for the underlying gem bo, pinning
refcounts) right. With the introduction of refcounted fbs the drm core
handled the fb refcounts, but still relied on drivers to update the
crtc->fb pointer (this approach required the least invasive changes in
drivers).

Enforce this contract with a WARN_ON.

Daniel Vetter 372835a852 drm/crtc-helper: explicit DPMS on after modeset
Atm the crtc helper implementation of set_config has really
inconsisten semantics: If just an fb update is good enough, dpms state
will be left as-is, but if we do a full modeset we force everything to
dpms on.

This change has already been applied to the i915 modeset code in

furthermore isn't even properly implemented on ilk+: Despite claims to

Nowadays (i.e. with Valleyview) we also have edp on non-PCH_SPLIT

Secondly we have full pfit pipe config tracking, so we'll correctly
disable the pfit as part of the initial modeset.

For fastboot we need a bit of work here to correctly kill unsupported
configs (if e.g. the pfit is used on anything else than the built-in
panel). But since that's not yet supported we don't need to worry.

Dragging random garbage along from the BIOS isn't a good idea, since

In the specific case for the bug reporter the BIOS used the 10bit
gamma table, but since we only support an 8bit table the dark colors
ended up all wrong and the light ones all unadjusted.

Note that this has a nice implication for fastboot, it essentially
means that we have quite a bit more state to check and compare before
we can decide whether fastboot is possible.

Christopher Harvey a080db9fdd drm/mgag200: Hardware cursor support
G200 cards support, at best, 16 colour palleted images for the cursor
so we do a conversion in the cursor_set function, and reject cursors
with more than 16 colours, or cursors with partial transparency. Xorg
falls back gracefully to software cursors in this case.

We can't disable/enable the cursor hardware without causing momentary
corruption around the cursor. Instead, once the cursor is on we leave
it on, and simulate turning the cursor off by moving it
offscreen. This works well.

Since we can't disable -> update -> enable the cursors, we double
buffer cursor icons, then just move the base address that points to
the old cursor, to the new. This also works well, but uses an extra
page of memory.

The cursor buffers are lazily-allocated on first cursor_set. This is
to make sure they don't take priority over any framebuffers in case of
limited memory.

Here is a representation of how the bitmap for the cursor is mapped in G200 memory :

  Each line of color cursor use 6 Slices of 8 bytes. Slices 0 to 3
  are used for the 4bpp bitmap, slice 4 for XOR mask and slice 5 for
  AND mask. Each line has the following format:

      //      Byte 0  Byte 1  Byte 2  Byte 3  Byte 4  Byte 5  Byte 6 Byte 7
      //
      // S0:  P00-01  P02-03  P04-05  P06-07  P08-09  P10-11  P12-13 P14-15
      // S1:  P16-17  P18-19  P20-21  P22-23  P24-25  P26-27  P28-29 P30-31
      // S2:  P32-33  P34-35  P36-37  P38-39  P40-41  P42-43  P44-45 P46-47
      // S3:  P48-49  P50-51  P52-53  P54-55  P56-57  P58-59  P60-61 P62-63
      // S4:  X63-56  X55-48  X47-40  X39-32  X31-24  X23-16  X15-08 X07-00
      // S5:  A63-56  A55-48  A47-40  A39-32  A31-24  A23-16  A15-08 A07-00

Disable them all in drm_fb_helper_restore_fbdev_mode.

After the cursors and planes have been disabled, user space needs to
explicitly re-enable them to make them visible again.

drm_plane_force_disable() will forcibly disable the plane even if user

The code was simply pulled from drm_framebuffer_remove(), which now
calls the new function as well.

Mika Kuoppala aa60c664e6 drm/i915: find guilty batch buffer on ring resets
After hang check timer has declared gpu to be hung,
rings are reset. In ring reset, when clearing
request list, do post mortem analysis to find out
the guilty batch buffer.

Select requests for further analysis by inspecting
the completed sequence number which has been updated
into the HWS page. If request was completed, it can't
be related to the hang.

For noncompleted requests mark the batch as guilty
if the ring was not waiting and the ring head was
stuck inside the buffer object or in the flush region
right after the batch. For everything else, mark
them as innocents.

v2: Fixed a typo in commit message (Ville Syrjälä)

v3: - more descriptive function parameters (Chris Wilson)
    - use masked head address when inspecting if request is in ring
    - s/hangcheck.last_action/hangcheck.action

Ville Syrjälä e0d8d59b08 drm/i915: Try harder to disable trickle feed on VLV
The specs are a bit unclear whether the per-plane trickle feed disable
control exists on VLV. There is another trickle feed disable control
in the MI_ARB register.

After some experimentation it turns out both the DSPCNTR trickle feed
bits and the MI_ARB bit can be toggled. However the DSPCNTR bits don't
seem to have any effect.

The MI_ARB bit, on the other hand, has a noticable effect. I performed
an experiment where I reduced the FIFO size via DSPARB and observed the
effect of the MI_ARB trickle feed bit on the display.

Using a 1920x1080-60 mode, with MI_ARB=0x4 the display started to have
problems with DSPARB=0x42424242, whereas with MI_ARB=0x0 the problems
didn't start until DSPARB=0x09090909. This seems to confirm that the
MI_ARB trickle feed bit actually does work.

So replace the use of the DSPCNTR trickle feed bits with MI_ARB
on VLV.

v2: Amend commit message with results from experimentation

Daniel Vetter 66e985c035 drm/i915: hw state readout and cross-checking for shared dplls
Just the plumbing, all the modeset and enable code has not yet been
switched over to use the new state. It seems to be decently broken
anyway, at least wrt to handling of the special pixel mutliplier
enabling sequence. Follow-up patches will clean up that mess.

Another missing piece is more careful handling (and fixup) of the fp1
alternate divisor state. The BIOS most likely doesn't bother to
program that one to what we expect. So we need to be more careful with
comparing that state, both for cross checking but also when checking
for dpll sharing when acquiring shared dpll. Otherwise fastboot will
deny a few shared dpll configurations which would otherwise work.

v2: We need to memcpy the pipe config dpll hw state into the pll, for
otherwise the cross-check code will get angry.

v3: Don't forget to read the pch pll state in the crtc get_pipe_config
function for ibx/ilk platforms.

v2:

- Also cross check the enabled crtc counting.

Note that I've botched up the patch ordering, and before this patch

Alex Deucher f100380ecd drm/radeon: fix AVI infoframe generation
- remove adding 2 to checksum, this is incorrect.

This was incorrectly introduced in:
92db7f6c86
http://lists.freedesktop.org/archives/dri-devel/2011-December/017717.html
However, the off by 2 was due to adding the version twice.
From the examples in the URL above:

[Rafał Miłecki][RV620] fglrx:
0x7454: 00 A8 5E 79     R600_HDMI_VIDEOINFOFRAME_0
0x7458: 00 28 00 10     R600_HDMI_VIDEOINFOFRAME_1
0x745C: 00 48 00 28     R600_HDMI_VIDEOINFOFRAME_2
0x7460: 02 00 00 48     R600_HDMI_VIDEOINFOFRAME_3
===================
(0x82 + 0x2 + 0xD) + 0x1F8 = 0x289
-0x289 = 0x77

However, the payload sum is not 0x1f8, it's 0x1f6.
00 + A8 + 5E + 00 +
00 + 28 + 00 + 10 +
00 + 48 + 00 + 28 +
00 + 48 =
0x1f6

Bits 25:24 of HDMI_VIDEOINFOFRAME_3 are the packet version, not part
of the payload.  So the total would be:
(0x82 + 0x2 + 0xD) + 0x1f6 = 0x287
-0x287 = 0x79

- properly emit the AVI infoframe version.  This was not being
emitted previous which is probably what caused the issue above.

This should fix blank screen when HDMI audio is enabled on
certain monitors.

Ville Syrjälä e6e792092e drm/edid: Add both 60Hz and 59.94Hz CEA modes to connector's mode list
Having both modes can be beneficial for video playback cases. If you can
match the video framerate exactly, and the audio and video clocks come
from the same source, you should be able to avoid dropped/repeated
frames without expensive operations such as resampling the audio to
match video output rate.

Rather than add both variants based on the CEA extension short video
descriptors in do_cea_modes(), add only one variant there. Once all
the EDID has been fully probed, do a loop over the entire probed mode
list, during which we add the other variants for all modes that match
CEA modes. This allows us to match modes that didn't come via the CEA
short video descriptors. For example one Samsung TV here doesn't have
the 640x480-60 mode as a SVD, but instead it's specified via a detailed
timing descriptor.

Daniel Vetter c0d43d6223 drm/i915: hw state readout for shared pch plls
Well, the first step of a long road at least, it only reads out
the pipe -> shared dpll association thus far. Other state which needs
to follow:

- hw state of the dpll (on/off + dpll registers). Currently we just
  read that out from the hw state, but that doesn't work too well when
  the dpll is in use, but not yet fully enabled. We get away since
  most likely it already has been enabled and so the correct state is
  left behind in the registers. But that doesn't hold for atomic
  modesets when we want to enable all pipes at once.

- Refcount reconstruction for each dpll.

- Cross-checking of all the above. For that we need to keep the dpll
  register state both in the pipe and in the shared_dpll struct, so
  that we can check that every pipe is still connected to a correctly
  configured dpll.

Note that since the refcount resconstruction isn't done yet this will
spill a few WARNs at boot-up while trying to disable pch plls which
have bogus refcounts. But since there's still a pile of refactoring to
do I'd like to lock down the state handling as soon as possible hence
decided against reordering the patches to quiet these WARNs - after
all the issues they're complaining about have existed since forever,
as Jesse can testify by having pch pll states blow up consistently in
his fastboot patches ...

v2: We need to preserve the old shared_dpll since currently the
shared dpll refcount dropping/getting is done in ->mode_set. With
the usual pipe_config infrastructure the old dpll id is already lost
at that point, hence preserve it in the new config.

v3: Rebase on top of the ips patch from Paulo.

v4: We need to unconditionally take over the shared_dpll id from the
old pipe config when e.g. doing a direct pch port -> cpu edp
transition.

v5: Move the saving of the old shared_dpll id to an ealier patch.

Daniel Vetter e2b7826742 drm/i915: switch crtc->shared_dpll from a pointer to an enum
Dealing with discrete enum values is simpler for hw state readout and
pipe config computations than pointers - having neat names instead of
chasing pointers should look better in the code.

This isn't a that good reason for pch plls, but on haswell we actually
have 3 different types of plls: WRPLL, SPLL and the DP clocks. Having
explicit names should help there.

Since this also adds the intel_crtc_to_shared_dpll helper to further
abstract away the crtc -> dpll relationship this will also help to
make the next patch simpler, which moves the shared dpll into the pipe
configuration.

Also note that for uniformity we have two special dpll ids: NONE for
pipes which need a shared pll but don't have one (yet) and private for
when there's a non-shared pll (e.g. per-pipe or per-port pll).

I've thought whether we should also add a 2nd enum for the type of the
pll we want (for really generic pll selection code) but thrown that
idea out again - likely there's too much platform craziness going on
to be able to share the pll selection logic much.

Since this touched all the shared_pll functions a bit I've also done
an s/intel_crtc/crtc/ replacement on a few of them.

v2: Kill DPLL_ID_NONE. It's probably better to call it DPLL_ID_INVALID and use
it to check that the compute config stage assigns a dpll to every pipe.
But since that code isn't ready yet until we move the dpll selection out
of the ->mode_set callback, there's no use for it.

Daniel Vetter e72f9fbf99 drm/i915: s/pch_pll/shared_dpll/
For fastboot we need some support to read out the sharing state of
plls, at least for platforms where they can be shared (or freely
assigned at least). Now for ivb we already have pretty extensive
infrastructure for tracking pch plls, and it took us an aweful lot of
tries to get that remotely right. Note that hsw could also share plls,
but even now they're already freely assignable. So we need this on
more than just ivb.

So on top of the usual fastboot fun pll sharing seems to be an
additional step up in fragility. Hence a common infrastructure for all
shared/freely assignable display plls seems to be in order.

The plan is to have a bit of dpll hw state readout code, which can be
used individually, but also to fill in the pipe config. The hw state
cross check code will then use that information to make sure that
after every modeset every pipe still is connected to a pll which still
has the correct configuration - a lot of the pch pll sharing bugs
where due to incorrect sharing.

We start this endeavour with a simple s/pch_pll/shared_dpll/ rename
job.

    drm/i915/sdvo: Use &intel_sdvo->ddc instead of intel_sdvo->i2c for DDC

Egbert Eich fixed a long-standing bug where we simply used a
non-working i2c controller to read the EDID for SDVO-LVDS panels.
Unfortunately some machines seem to not be able to cope with the mode
provided in the EDID. Specifically they seem to not be able to cope
with a 4x pixel mutliplier instead of a 2x one, which seems to have
been worked around by slightly changing the panels native mode in the
VBT so that the dotclock is just barely above 50MHz.

Since it took forever to notice the breakage it's fairly safe to
assume that at least for SDVO-LVDS panels the VBT contains fairly sane
data. So just switch around the order and use VBT modes first.

v2: Also add EDID modes just in case, and spell Egbert correctly.

v3: Elaborate a bit more about what's going on on Chris' machine.

Patrik Jakobsson 820de86a90 drm/gma500/psb: Unpin framebuffer on crtc disable
The framebuffer needs to be unpinned in the crtc->disable callback
because of previous pinning in psb_intel_pipe_set_base(). This will fix
a memory leak where the framebuffer was released but not unpinned
properly. This patch only affects Poulsbo.

Laurent Pinchart bda3fdaa0f drm/omap: Use drm_gem_mmap_obj() to implement dma-buf mmap
The dma-buf mmap code was copied from the GEM mmap implementation.
Replace it with the new drm_gem_mmap_obj() function.

Laurent Pinchart 1c5aafa6ee drm/gem: Split drm_gem_mmap() into object search and object mapping
The drm_gem_mmap() function first finds the GEM object to be mapped
based on the fake mmap offset and then maps the object. Split the object
mapping code into a standalone drm_gem_mmap_obj() function that can be
used to implement dma-buf mmap() operations.

Ville Syrjälä 22e407d749 drm/i915: Make g4x_fixup_plane() operational again
Don't enable the cursor until g4x_fixup_plane() had a chance to do
cast its magic spell.

Egbert writes:
"Today I had the chance to test this. First I tried
 if I can still reproduce the blank with this patch
 added when I disable my voodoo g4x_fixup_plane():
 It turned out it still happens however very rarely
 (like 1 out of 20 tries). When I reenabled my voodoo
 the issue still occurred.
 I had to switch two lines around, ie:

         intel_enable_plane(dev_priv, plane, pipe);
         if (IS_G4X(dev))
                 g4x_fixup_plane(dev_priv, pipe);
 +       intel_crtc_update_cursor(crtc, true);

 to avoid the blank screen issue - which is it didn't
 happen in ~75 tries."

v2: Add a comment to remind people of the ordering constraints

Rodrigo Vivi fd3da6c95b drm/i915: WA: FBC Render Nuke.
WaFbcNukeOn3DBlt for IVB, HSW.

According BSPec: "Workaround: Do not enable Render Command Streamer tracking for FBC.
Instead insert a LRI to address 0x50380 with data 0x00000004 after the PIPE_CONTROL that
follows each render submission."

v2: Chris noticed that flush_domains check was missing here and also suggested to do
    LRI only when fbc is enabled. To avoid do a I915_READ on every flush lets use the
    module parameter check.

v3: Adding Wa name as Damien suggested.

v4: Ville noticed VLV doesn't support fbc at all and comment came wrong from spec.

v5: Ville noticed than on blt a Cache Clean LRI should be used instead the Nuke one.

v6: Check for flush domain on blt (by Ville).
    Check for scanout dirty (by Chris).

v7: Apply proper fbc_dirty implemented by Chris.

v8: remove unused variables.
