Seung-Woo Kim 0d8071ee11 drm/exynos: added source size to overlay structure
Set plane has source size but exynos overlay structure did
not consider it. This patch adds source size to overlay
structure. For set crtc, source size is set from crtc size.

Alex Deucher 1b9c3dd022 drm/radeon: make use of radeon_gem_init() consistent
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.

Dave Airlie f9aa76a852 drm/kms: driver for virtual cirrus under qemu
This is the initial driver for emulated cirrus GPU found in qemu.
This driver only supports the emulated GPU and doesn't attempt
to bind to any real cirrus GPUs.

This driver is intended to be used with xf86-video-modesetting in userspace.
It requires at least version 0.3.0

This follow the same design as ast and mgag200, and is based on work
done by Matthew Garrett previously.

This GPU has no hw cursor, and it can't scanout 32-bpp, only packed 24-bpp.
i.e. it sucks.

it doesn't driver any of the Matrix G series desktop cards.

It will bind to G200 SE A,B, G200EV, G200WB, G200EH and G200ER cards.

Its based on previous work done my Matthew Garrett but remodelled
to follow the same style and flow as the AST server driver. It also
works along the same lines as the AST server driver wrt memory management.

There is no userspace driver planned, xf86-video-modesetting should be used.
It also appears these GPUs have no ARGB hw cursors.

v2: add missing tagfifo reset + G200 SE memory bw setup pieces.

Dave Airlie 312fec1405 drm: Initial KMS driver for AST (ASpeed Technologies) 2000 series (v2)
This is the initial driver for the Aspeed Technologies chips found in
servers. This driver supports the AST 2000, 2100, 2200, 2150 and 2300. It
doesn't support the AST11xx due to lack of hw to test it on, and them requiring
different codepaths.

This driver is intended to be used with xf86-video-modesetting in userspace.

This driver has a slightly different design than other KMS drivers, but
future server chips will probably share similiar setup. As these GPUs commonly
have low video RAM, it doesn't make sense to put the kms console in VRAM
always. This driver places the kms console into system RAM, and does dirty
updates to a copy in video RAM. When userspace sets a new scanout buffer,
it forcefully evicts the video RAM console, and X can create a framebuffer
that can use all of of video RAM.

This driver uses TTM but in a very simple fashion to control the eviction
to system RAM of the console, and multiple servers.

v2: add s/r support, fix Kconfig.

Highlights:
- sparse fixes from Ben.
- tons of little cleanups from Chris all over: tiling_changed
 clarification, deferred_free list removal, ...
- fix up irq handler on gen2 & gen3 + related cleanups from Chris
- prep work for wait_rendering_timeout from Ben with some nice
 refactorings
- first set of infoframe fixes from Paulo for doubleclocked CEA modes
- improve pch pll handling from Jesse and Chris
- gpu hangman, this also contains the reset fix for gen4
- rps sanity check from Chris - this papers over issues when the gpu fails
 to clock up on snb/ivb, and it is shockingly easy to hit. The code
 prints a big WARN backtrace and restores the hw to a sane state. The
 real fix is still in the works.

Atm I'm aware of 2 regressions in -next:
- One of the gmbus patches (not gmbus itself) regressed lvds detection on
 a MacbookPro. I've analyzed the bug already and I think I know what's
 going on, patch is awaiting test feedback.
- Just today QA reported that DP on ilk regressed. That bug is fresh of
 the press and still awaiting detailed logfiles and the bisect result.
 The only thing that's clear atm is that -fixes works and -next doesn't.

Rob Clark b06d66be3b drm: pass dev to drm_vm_{open,close}_locked()
Previously these functions would assume that vma->vm_file was the
drm_file.  Although if in some cases if the drm driver needs to use
something else for the backing file (such as the tmpfs filp) then this
assumption is no longer true.  But vma->vm_private_data is still the
GEM object.

With this change, now the drm_device comes from the GEM object rather
than the drm_file so the driver is more free to play with vma->vm_file.

The scenario where this comes up is for mmap'ing of cached dmabuf's
for non-coherent systems, where the driver needs to use fault handling
and PTE shootdown to simulate coherency.  We can't use the vma->vm_file
of the dmabuf, which is using anon_inode's address_space.  The most
straightforward thing to do is to use the GEM object's obj->filp for
vma->vm_file in all cases, for which we need this patch.

Currently the code re-reads PCH_IIR during the hotplug interrupt

for handling a spurious interrupt as we then may not clear all the
interrupts processed (since the re-read IIR may contains more interrupts

Daniel Vetter 59de3295ad drm/i915: enable semaphores on gen6 if dmar is not active
Inspired by the recent ppgtt regression report, where switching of
dmar only for the gpu seems to fix things completely, I've looked
again at the semaphores+vt-d situation.

Contrary to my earlier testing a few months back my system is now
stable with dmar disabled for the igd, and not only when disabling
dmar completely.

So I'm rather hopeful that all our recent fixes for snb have changed
things for code and it's time to try enabling semaphores again. We've
also had issues with enabling semaphores which are not vt-d related,
but I guess these are all fixed by the autoreport-disabling and lazy
request fix. And there's only one way to find out whether there are
still other issues ...

When I've tried to apply this patch I've noticed that semaphores on
gen6 have already silently been enabled in

    drm/i915: use semaphores for the display plane

Fix this up by only checking whether dmar is enabled on the gfx (not
on the entire system).

Christian König c3b7fe8b8a drm/radeon: multiple ring allocator v3
A startover with a new idea for a multiple ring allocator.
Should perform as well as a normal ring allocator as long
as only one ring does somthing, but falls back to a more
complex algorithm if more complex things start to happen.

We store the last allocated bo in last, we always try to allocate
after the last allocated bo. Principle is that in a linear GPU ring
progression was is after last is the oldest bo we allocated and thus
the first one that should no longer be in use by the GPU.

If it's not the case we skip over the bo after last to the closest
done bo if such one exist. If none exist and we are not asked to
block we report failure to allocate.

If we are asked to block we wait on all the oldest fence of all
rings. We just wait for any of those fence to complete.

v2: We need to be able to let hole point to the list_head, otherwise
    try free will never free the first allocation of the list. Also
    stop calling radeon_fence_signalled more than necessary.

v3: Don't free allocations without considering them as a hole,
    otherwise we might lose holes. Also return ENOMEM instead of ENOENT
    when running out of fences to wait for. Limit the number of holes
    we try for each ring to 3.

Jerome Glisse 3b7a2b24ea drm/radeon: rework fence handling, drop fence list v7
Using 64bits fence sequence we can directly compare sequence
number to know if a fence is signaled or not. Thus the fence
list became useless, so does the fence lock that mainly
protected the fence list.

Things like ring.ready are no longer behind a lock, this should
be ok as ring.ready is initialized once and will only change
when facing lockup. Worst case is that we return an -EBUSY just
after a successfull GPU reset, or we go into wait state instead
of returning -EBUSY (thus delaying reporting -EBUSY to fence
wait caller).

v2: Remove left over comment, force using writeback on cayman and
    newer, thus not having to suffer from possibly scratch reg
    exhaustion
v3: Rebase on top of change to uint64 fence patch
v4: Change DCE5 test to force write back on cayman and newer but

    prefix for all function names. Even if it's now highly optimized,

Jerome Glisse bb63556729 drm/radeon: convert fence to uint64_t v4
This convert fence to use uint64_t sequence number intention is
to use the fact that uin64_t is big enough that we don't need to
care about wrap around.

Tested with and without writeback using 0xFFFFF000 as initial
fence sequence and thus allowing to test the wrap around from
32bits to 64bits.

v2: Add comment about possible race btw CPU & GPU, add comment
    stressing that we need 2 dword aligned for R600_WB_EVENT_OFFSET
    Read fence sequenc in reverse order of GPU write them so we
    mitigate the race btw CPU and GPU.

v3: Drop the need for ring to emit the 64bits fence, and just have
    each ring emit the lower 32bits of the fence sequence. We
    handle the wrap over 32bits in fence_process.

v4: Just a small optimization: Don't reread the last_seq value
    if loop restarts, since we already know its value anyway.
    Also start at zero not one for seq value and use pre instead
    of post increment in emmit, otherwise wait_empty will deadlock.

Merge tag 'v3.4-rc6' into drm-intel-next

Conflicts:
	drivers/gpu/drm/i915/intel_display.c

Ok, this is a fun story of git totally messing things up. There
/shouldn't/ be any conflict in here, because the fixes in -rc6 do only
touch functions that have not been changed in -next.

The offending commits in drm-next are 14415745b2..1fa611065 which
simply move a few functions from intel_display.c to intel_pm.c. The
problem seems to be that git diff gets completely confused:

$ git diff 14415745b2..1fa611065

is a nice mess in intel_display.c, and the diff leaks into totally
unrelated functions, whereas

$git diff --minimal  14415745b2..1fa611065

is exactly what we want.

Unfortunately there seems to be no way to teach similar smarts to the
merge diff and conflict generation code, because with the minimal diff
there really shouldn't be any conflicts. For added hilarity, every
time something in that area changes the + and - lines in the diff move
around like crazy, again resulting in new conflicts. So I fear this
mess will stay with us for a little longer (and might result in
another backmerge down the road).

Daniel Vetter d54423037f drm/i915: allow the existing error_state to be destroyed
... by writing (anything) to i915_error_state.

This way we can simulate a bunch of gpu hangs and run the error_state
capture code every time (without the need to reload the module).

To make that happen we need to abandon the simple seq_file wrappers
provided by the drm core. While at it put the new error_state
refcounting to some good use and associated the error_state to the
debugfs when opening the file. Otherwise the error_state could change
while someone is reading it. This should help greatly when we finally
get around to split up the giant single seq_file block that the
error_state file currently is into smaller parts.

Daniel Vetter e5eb3d63c6 drm/i915: add interface to simulate gpu hangs
gpu reset is a very important piece of our infrastructure.
Unfortunately we only really it test by actually hanging the gpu,
which often has bad side-effects for the entire system. And the gpu
hang handling code is one of the rather complicated pieces of code we
have, consisting of
- hang detection
- error capture
- actual gpu reset
- reset of all the gem bookkeeping
- reinitialition of the entire gpu

This patch adds a debugfs to selectively stopping rings by ceasing to
update the hw tail pointer, which will result in the gpu no longer
updating it's head pointer and eventually to the hangcheck firing.
This way we can exercise the gpu hang code under controlled conditions
without a dying gpu taking down the entire systems.

Patch motivated by me forgetting to properly reinitialize ppgtt after
a gpu reset.

Usage:

echo $((1 << $ringnum)) > i915_ring_stop # stops one ring

echo 0xffffffff > i915_ring_stop # stops all, future-proof version

then run whatever testload is desired. i915_ring_stop automatically
resets after a gpu hang is detected to avoid hanging the gpu to fast
and declaring it wedged.

v2: Incorporate feedback from Chris Wilson.

v3: Add the missing cleanup.

v4: Fix up inconsistent size of ring_stop_read vs _write, noticed by
Eugeni Dodonov.

Daniel Vetter c6ebd4c015 drm/i915: use mode values consistently when converting to sdvo dtd
The drm_mode->dtd conversion used the crtc timings, whereas the
dtd->drm_mod did not set these. Use the standard mode information, not
the crtc timings, in both cases to make these two functions proper
inverses of each another.

Note that this also kills the risk that we handle interlaced timings
inconsistently because the drm core uses half-frames for crtc timings,
whereas we need full frames. But interlaced support is pretty decently
broken anyway for sdvo encoders, so no big deal.

    drm/i915: fixup overlay checks for interlaced modes

the only places we actually need the crtc timings is in the mode_set
function.

I guess the idea of the drm core is that every time it creates a drm
mode, it also sets the timings. But afaics it never uses them, safe
for the precise vblank timestamp code (but that can only run on active
modes, i.e.  after our mode_fixup functions have been called). The
problem is that drm core always sets CRTC_INTERLACE_HALVE_V, so the
timings are pretty much bogus for us anyway (at least with interlaced
support).

So I guess it's the drivers job that every active modes needs to have
crtc timings that suits it, and with these patches we should have
that. drm core doesn't seem to care about modes that just get passed
around. Hence we can now safely rip out all the remaining calls to
set_crtcinfo left in the driver and clean up this confusion.

whereby it seems that we begin suppressing power management interrupts,

This patch does have a side-effect. It removes the mark-busy for just
moving the cursor - we don't want to increase the render clock just for
the sprite, though we may want to bump the display frequency. I'd argue
that we do not, and certainly don't want to take the struct_mutex here
due to the large latencies that introduces.

Chris Wilson e04c735029 drm/i915: Wait for the clocks to stabilise before updating PLLs
When initialising the PLL registers we may have to clear existing state
from the BIOS - that is the PLL may already be enabled. So we need to
disable it, wait for the clocks to settle and then rewrite it.

The issue came to light when Ben tested

and found that booting into a VGA monitor was no longer working. Closer
inspection suggests that it was a pre-existing bug now being hit by the
rearranged code. Perhaps Ben was not even the first person to stumble
upon this bug, https://bugs.freedesktop.org/show_bug.cgi?id=37029.

Daniel Vetter 316d388450 drm/i915: rework legacy GFX HWS handling
To get the fun stuff out of the way, the legacy hws is allocated by
userspace when the gpu needs a gfx hws. And there's no reference-counting
going on, so userspace can simply screw everyone over.

At least it's not as horrible as i810, where the ringbuffer is allocated
by userspace ...

We can't fix this disaster, but we can at least tidy up the code a
bit to make things clearer:
- Drop the drm ioremap indirection.
- Add a new new read_legacy_status_page to paper over the differences
  between the legacy gfx hws and the physical hws shared with the
  new ringbuffer code.
- Add a pointer in dev_priv->dri1 for the cpu addresses - that one is
  an iomem remapping as opposed to all other hw status pages. This is
  just prep work to make sparse happy.

and make the caller responsible for retiring if the action is desired.

We always set it so there's no point in checking. We could
instead add a bit that tells us whether gem is actually
initialized (i.e. either kms or gem_init_ioctl called), but
that's imho not worth it.

So just rip it out.

There's a little change in the wait_ring timeout, but we've never
run with anything else than the 60 second timeout, even on dri1
userspace.

Chris Wilson 1488fc08c1 drm/i915: Remove the deferred-free list
The use of the mm_list by deferred-free breaks the following patches to
extend the range of objects tracked. We can simplify things if we just
make the unbind during free uninterrutible.

Note that unbinding should never fail, because we hold an additional
reference on every active object. Only the ilk vt-d workaround breaks
this, but already takes care of not failing by waiting for the gpu to
quiescent non-interruptible. But the existence of the deferred free
list casted some doubts on this theory, hence WARN if the unbind fails
and only then retry non-interruptible.

We can kill this additional code after a release in case the theory is
indeed right and no one has hit that WARN.

Chris Wilson 8325a09dd0 drm/i915: Bump the inactive LRU on set-to-GTT-domain
Currently, we only bump the inactive LRU of an object when we bind
into the GTT for a page-fault. As the object may be used many times
before its mapping is zapped, we do not mark it as active as
frequently as we should. Userspace should be calling set-to-GTT-domain
before each pointer deference (for synchronous access) and so is a
good place to mark the buffer as active.

Marking the buffer as recently used places it at the end of the
inactive eviction queue, though still before anything with outstanding
rendering. This reduces the likelihood of evicting a buffer that is
going to be used again by the CPU in the near future. This way we can
hopefully avoid to kick out upload buffers right before we use them on
the gpu.

Note that we need to check that the object is not active or pinned,
for otherwise we create havoc on the active/pinned lists, which also
use obj->mm_list.

The active lists are sorted by and evicted in last GPU rendering
order, access by the CPU to a still active buffer therefore does not
affect its eviction ordering. Pinned objects are currently excluded
from eviction, therefore the only list that we need to bump for GTT
access by the CPU is the inactive list.

Rename obj->tiling_changed to obj->fence_dirty so that it is clear that
it flags when the parameters for an active fence (including the
no-fence) register are changed.

Also, do not set this flag when the object does not have a fence
register allocated currently and the gpu does not depend upon the
unfence. This case works exactly like when a tiled object lost its
fence and hence does not need additional handling for the tiling
change in the code.

Chris Wilson e90f3b61f4 drm/i915: Only enable IPS polling for gen5
On SandyBridge IPS was entirely implemented in hardware and not reliant
on the driver monitoring power consumption and feeding back desired run
states, so the hardware is able to adapt quicker and more flexibly. Which
is a huge relief for us as we no longer have to carry empirically
derived magic algorithms.

Yet despite the advance in technology, the driver was still doing its
IPS polling on all machines. Restrict it to the only supported hardware,
Clarkdale/Arrandale.

Daniel Vetter writes:

A new drm-intel-next pull. Highlights:
- More gmbus patches from Daniel Kurtz, I think gmbus is now ready, all
 known issues fixed.
- Fencing cleanup and pipelined fencing removal from Chris.
- rc6 residency interface from Ben, useful for powertop.
- Cleanups and code reorg around the ringbuffer code (Ben&me).
- Use hw semaphores in the pageflip code from Ben.
- More vlv stuff from Jesse, unfortunately his vlv cpu is doa, so less
 merged than I've hoped for - we still have the unused function warning :(
- More hsw patches from Eugeni, again, not yet enabled fully.
- intel_pm.c refactoring from Eugeni.
- Ironlake sprite support from Chris.
- And various smaller improvements/fixes all over the place.

Note that this pull request also contains a backmerge of -rc3 to sort out
a few things in -next. I've also had to frob the shortlog a bit to exclude
anything that -rc3 brings in with this pull.

Regression wise we have a few strange bugs going on, but for all of them
closer inspection revealed that they've been pre-existing, just now
slightly more likely to be hit. And for most of them we have a patch
already. Otherwise QA has not reported any regressions, and I'm also not
aware of anything bad happening in 3.4.

Kenneth Graunke 3a69ddd6f8 drm/i915: Set the Stencil Cache eviction policy to non-LRA mode.
Clearing bit 5 of CACHE_MODE_0 is necessary to prevent GPU hangs in
OpenGL programs such as Google MapsGL, Google Earth, and gzdoom when
using separate stencil buffers.  Without it, the GPU tries to use the
LRA eviction policy, which isn't supported.  This was supposed to be off
by default, but seems to be on for many machines.

This cannot be done in gen6_init_clock_gating with most of the other
workaround bits; the render ring needs to exist.  Otherwise, the
register write gets dropped on the floor (one printk will show it
changed, but a second printk immediately following shows the value
reverts to the old one).

Some boards such as the Intel D2700MUD allow you to have over 4GB of RAM.
The GTT on the PVR based devices is 32bit however. Hugh Dickins points out

This is not the whole fix for the problem. Some further shmem patches will
be needed to deal with the corner cases.
