Git commit 90797e6d1ec0dfde6ba62a48b9ee3803887d6ed4
("drm/i915: create compact dma scatter lists for gem objects") makes
certain assumptions about the under laying DMA API that are not always
correct.
On a ThinkPad X230 with an Intel HD 4000 with Xen during the bootup
I see:
[drm:intel_pipe_set_base] *ERROR* pin & fence failed
[drm:intel_crtc_set_config] *ERROR* failed to set mode on [CRTC:3], err = -28
Bit of debugging traced it down to dma_map_sg failing (in
i915_gem_gtt_prepare_object) as some of the SG entries were huge (3MB).
That unfortunately are sizes that the SWIOTLB is incapable of handling -
the maximum it can handle is a an entry of 512KB of virtual contiguous
memory for its bounce buffer. (See IO_TLB_SEGSIZE).
Previous to the above mention git commit the SG entries were of 4KB, and
the code introduced by above git commit squashed the CPU contiguous PFNs
in one big virtual address provided to DMA API.
This patch is a simple semi-revert - were we emulate the old behavior
if we detect that SWIOTLB is online. If it is not online then we continue
on with the new compact scatter gather mechanism.
An alternative solution would be for the the '.get_pages' and the
i915_gem_gtt_prepare_object to retry with smaller max gap of the
amount of PFNs that can be combined together - but with this issue
discovered during rc7 that might be too risky.

One remaining regression fix for i915. I've left it in -fixes for more
than a week since it's in tricky code, and it took us a few kernel
releases to notice the regression at all. The fence leak is especially
annoying on gen2/3 and will kill userspace there quickly. For extra
paranoia we've added a WARN in -next to catch this, things seem to be
solid now.

The omapdrm driver currently uses a string comparison to find out if the
display is a DVI display. This is not reliable, and as we now have a
specific display type for DVI, let's use that.

Now that omap_dss_output has been combined into omap_dss_device, we can
add ref counting for the relevant output functions also.
This patch adds omap_dss_get_device() calls to the various find_output()
style functions. This, of course, means that the users of those
find_output functions need to do a omap_dss_put_device() after use.

We currently have omap_dss_device, which represents an external display
device, sometimes an external encoder, sometimes a panel. Then we have
omap_dss_output, which represents DSS's output encoder.
In the future with new display device model, we construct a video
pipeline from the display blocks. To accomplish this, all the blocks
need to be presented by the same entity.
Thus, this patch combines omap_dss_output into omap_dss_device. Some of
the fields in omap_dss_output are already found in omap_dss_device, but
some are not. This means we'll have DSS output specific fields in
omap_dss_device, which is not very nice. However, it is easier to just
keep those output specific fields there for now, and after transition to
new display device model is made, they can be cleaned up easier than
could be done now.

We currently have two steps in panel initialization and startup: probing
and enabling. After the panel has been probed, it's ready and can be
configured and later enabled.
This model is not enough with more complex display pipelines, where we
may have, for example, two panels, of which only one can be used at a
time, connected to the same video output.
To support that kind of scenarios, we need to add new step to the
initialization: connect.
This patch adds support for connecting and disconnecting panels. After
probe, but before connect, no panel ops should be called. When the
connect is called, a proper video pipeline is established, and the panel
is ready for use. If some part in the video pipeline is already
connected (by some other panel), the connect call fails.
One key difference with the old style setup is that connect() handles
also connecting to the overlay manager. This means that the omapfb (or
omapdrm) no longer needs to figure out which overlay manager to use, but
it can just call connect() on the panel, and the proper overlay manager
is connected by omapdss.
This also allows us to add back the support for dynamic switching
between two exclusive panels. However, the current panel device model is
not changed to support this, as the new device model is implemented in
the following patches and the old model will be removed. The new device
model supports dynamic switching.

Currently omapdrm creates crtcs, which map directly to DSS overlay
managers, only on demand at init time. This would make it difficult to
manage connecting the display entities in the future, as the code cannot
just search for a suitable overlay manager.
We cannot fix this the sane way, which would be to create crtcs for each
overlay manager, because we need an overlay for each crtc. With limited
number of overlays, that's not possible.
So the solution for now is to detach the overlay manager from the crtc.
crtcs are still created on demand at init time, but all overlay managers
are always initialized by the omapdss.
This way we can create and connect whole display pipelines from the
overlay manager to the display, regardless of which crtcs omapdrm would
create.

Add two helper functions that can be used to find either the DSS output
or the overlay manager that is connected to the given display.
This hides how the output and the manager are actually connected, making
it easier to change the connections in the future.

Stéphane Marchesin found that fences for pinned objects (i.e. the
scanout) were not being restored upon resume, leading to corruption on
the display and reference counting issues. This is due to a bug in
commit 312817a39f17dbb4de000165b5b724e3728cd91c [2.6.38]
Author: Chris Wilson <chris@chris-wilson.co.uk>

drm/i915: Only save and restore fences for UMS
that zapped the pinned fences even though they were in use.
Fortuitously, whilst we forced a VT switch during suspend and resume,
no fences were ever pinned at the time. However, we now can do
switchless S3 transitions and so the old bug finally surfaces.

If a buffer is never bound to a virtual memory pagetable than don't try
to unbind it. Only drawback is that we don't update the pagetable when
unbinding the ib pool buffer which is fine because it only happens at
suspend or module unload/shutdown.
Fixes spurious messages about buffers without VM mappings. E.g.:
radeon 0000:01:00.0: bo ffff88020afac400 don't has a mapping in vm ffff88021ca2b900

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.

sdvo->hotplug_active is initialised during intel_sdvo_setup_outputs(),
and so we never enabled the hotplug interrupts on SDVO as we were
checking too early.
This regression has been introduced somewhere in the hpd rework for
the storm detection and handling starting with
commit 1d843f9de4e6dc6a899b6f07f106c00da09925e6

DRM/I915: Add enum hpd_pin to intel_encoder.
and the follow-up patches to use the new encoder->hpd_pin variable for
the different irq setup functions.
The problem is that encoder->hpd_pin was set up _before_ the output
setup was done and so before we could assess the hotplug capabilities
of the outputs on an sdvo encoder.

In intel_sdvo_get_lvds_modes() the wrong i2c adapter record is used
for DDC. Thus the code will always have to rely on a LVDS panel
mode supplied by VBT.
In most cases this succeeds, so this didn't get detected for quite
a while.
This regression seems to have been introduced in

The current radeon driver initialization routines, when using KMS, are written
so that the IRQ installation routine is called before initializing the WB buffer
and the CP rings. With some ASICs, though, the IRQ routine tries to access the
GFX_INDEX ring causing a call to RREG32 with the value of -1 in
radeon_fence_read. This, in turn causes the system to completely hang with some
cards, requiring a hard reset.
A call stack that can cause such a hang looks like this (using rv515 ASIC for the
example here):
* rv515_init (rv515.c)
* radeon_irq_kms_init (radeon_irq_kms.c)
* drm_irq_install (drm_irq.c)
* radeon_driver_irq_preinstall_kms (radeon_irq_kms.c)
* rs600_irq_process (rs600.c)
* radeon_fence_process - due to SW interrupt (radeon_fence.c)
* radeon_fence_read (radeon_fence.c)
* hang due to RREG32(-1)
The patch moves the IRQ installation to the card startup routine, after the ring
has been initialized, but before the IRQ has been set. This fixes the issue, but
requires a check to see if the IRQ is already installed, as is the case in the
system resume codepath.
I have tested the patch on three machines using the rv515, the rv770 and the
evergreen ASIC. They worked without issues.
This seems to be a known issue and has been reported on several bug tracking
sites by various distributions (see links below). Most of reports recommend
booting the system with KMS disabled and then enabling KMS by reloading the
radeon module. For some reason, this was indeed a usable workaround, however,
UMS is now deprecated and disabled by default.

Last year, a patch was made for the "HP t5740e Thin Client" (see
http://lists.freedesktop.org/archives/dri-devel/2012-May/023245.html).
This device reports an lvds panel, but does not really have one.
The predecessor of this device is the "hp t5740", which also does not have
an lvds panel. This patch will add the same quirk for this device.

If we always force the pipe A to on we can't use the hw state to
decide whether it should be on. Hence quirk the quirk.
The problem is that crtc->active tracks the state of the entire
display pipe, i.e. including planes, encoders and all. But our hw
state readout simply looks at the pipe. But with the pipe A quirk we
force-enable that (together with it's pll). To fix that mismatch we
have two options:
- Quirk the checked state to match what our sw tracking states if the
pipe A quirk is in effect.
- Improve the hw state readout to not get fooled by the pipe A quirk.
Since we already have similar state clamping in e.g. assert_pipe I've
opted for the first variant. Also note that we don't really loose any
state checking: Individual pieces of the abstract crtc pipe are
checked in the enable/disable functions with the various asssert_*
checks we have, and the hw state check code doesn't check anything if
the pipe is off anyway.
v2: Pimp commit message after discussion with Chris and only apply the
quirk for the quirk if we're checking pipe A. Otherwise we'll miss
state checking for pipe B on i830M ...
v3: Make the code comment consistent with the improved commit message,
too (Chris).

drm/i915: clear up wedged transitions
X can again get -EIO when it does not expect it. And even worse score
a SIGBUS when accessing gtt mmaps. The established ABI is that we
_only_ return an -EIO from execbuf - all other ioctls should just
work. And since the reset code moves all bos out of gpu domains and
clears out all the last_seqno/ring tracking there really shouldn't be
any reason for non-execbuf code to ever touch the hw and see an -EIO.
After some extensive discussions we've noticed that these spurios -EIO
are caused by i915_gem_wait_for_error:
http://www.mail-archive.com/intel-gfx@lists.freedesktop.org/msg20540.html
That is easy to fix by returning 0 instead of -EIO, since grabbing the
dev->struct_mutex does not yet mean that we actually want to touch the
hw. And so there is no reason at all to fail with -EIO.
But that's not the entire since, since often (at least it's easily
googleable) dmesg indicates that the reset fails and we declare the
gpu wedged. Then, quite a bit later X wakes up with the "Timed out
waiting for the gpu reset to complete" DRM_ERROR message in
wait_for_errror and brings down the desktop with an -EIO/SIGBUS.
So clearly we're missing a wakeup somewhere, since the gpu reset just
doesn't take 10 seconds to complete. And indeed we're do handle the
terminally wedged state wrong.
Fix this all up.

strange, but it seems one has to always select both BACKLIGHT_CLASS_DEVICE
