81103355b1 drm/vmwgfx: Fix dma API layer violation
Remove the check for IOMMU presence since it was considered a
layer violation.
This means we have no reliable way to destinguish between coherent
hardware IOMMU DMA address translations and incoherent SWIOTLB DMA
address translations, which we can't handle. So always presume the
former. This means that if anybody forces SWIOTLB without also setting
the vmw_force_coherent=1 vmwgfx option, driver operation will fail,
like it will on most other graphics drivers.

aa8e2435b3 drm/ttm: Define a single DRM_FILE_PAGE_OFFSET constant
Most TTM drivers define the constant DRM_FILE_PAGE_OFFSET of the same
value. The only exception is vboxvideo, which is being converted to the
new offset by this patch. Unifying the constants in a single place
simplifies the driver code.

1ff494813b drm/irq: Ditch DRIVER_IRQ_SHARED
This is only used by drm_irq_install(), which is an optional helper.
For legacy pci devices this is required (due to interrupt sharing without
msi/msi-x), and just making this the default exactly matches the behaviour
of all existing drivers using the drm_irq_install() helpers. In case that
ever becomes wrong drivers can roll their own irq handling, as many
drivers already do (for other reasons like needing a threaded interrupt
handler, or having an entire pile of different interrupt sources).

v2: Rebase

v3: Improve commit message (Emil)

5b38e7475e drm/irq: Don't check for DRIVER_HAVE_IRQ in drm_irq_(un)install
If a non-legacy driver calls these it's valid to assume there is
interrupt support. The flag is really only needed for legacy drivers,
which control IRQ enabling/disabling through the DRM_IOCTL_CONTROL
legacy IOCTL.

Also remove all the flag usage from non-legacy drivers.

v2: Review from Emil:

2b3cd6249b drm/vmwgfx: fix the check when to use dma_alloc_coherent
Since Linux 4.21 we merged the swiotlb ops into the DMA direct ops,
so they would always have a the sync_single methods.  But late in
the cicle we also removed the direct ops entirely, so we'd see NULL
DMA ops.  Switch vmw_dma_select_mode to only detect swiotlb presence
using swiotlb_nr_tbl() instead.

af7ddd8a62 DMA mapping updates for Linux 4.21
A huge update this time, but a lot of that is just consolidating or
 removing code:
 
  - provide a common DMA_MAPPING_ERROR definition and avoid indirect
    calls for dma_map_* error checking
  - use direct calls for the DMA direct mapping case, avoiding huge
    retpoline overhead for high performance workloads
  - merge the swiotlb dma_map_ops into dma-direct
  - provide a generic remapping DMA consistent allocator for architectures
    that have devices that perform DMA that is not cache coherent. Based
    on the existing arm64 implementation and also used for csky now.
  - improve the dma-debug infrastructure, including dynamic allocation
    of entries (Robin Murphy)
  - default to providing chaining scatterlist everywhere, with opt-outs
    for the few architectures (alpha, parisc, most arm32 variants) that
    can't cope with it
  - misc sparc32 dma-related cleanups
  - remove the dma_mark_clean arch hook used by swiotlb on ia64 and
    replace it with the generic noncoherent infrastructure
  - fix the return type of dma_set_max_seg_size (Niklas Söderlund)
  - move the dummy dma ops for not DMA capable devices from arm64 to
    common code (Robin Murphy)
  - ensure dma_alloc_coherent returns zeroed memory to avoid kernel data
    leaks through userspace.  We already did this for most common
    architectures, but this ensures we do it everywhere.
    dma_zalloc_coherent has been deprecated and can hopefully be
    removed after -rc1 with a coccinelle script.

fd56746775 drm/vmwgfx: Protect from excessive execbuf kernel memory allocations v3
With the new validation code, a malicious user-space app could
potentially submit command streams with enough buffer-object and resource
references in them to have the resulting allocated validion nodes and
relocations make the kernel run out of GFP_KERNEL memory.

Protect from this by having the validation code reserve TTM graphics
memory when allocating.

13289241fe drm/vmwgfx: Remove the resource avail field
This field was previously used to prevent a lookup of a resource before its
constructor had run to its end. This was mainly intended for an interface
that is now removed that allowed looking up a resource by its device id.

Currently all affected resources are added to the lookup mechanism (its
TTM prime object is initialized) late in the constructor where it's OK to
look up the resource.

This means we can change the device resource_lock to an ordinary spinlock
instead of an rwlock and remove a locking sequence during lookup.

f1d34bfd70 drm/vmwgfx: Replace vmw_dma_buffer with vmw_buffer_object
Initially vmware buffer objects were only used as DMA buffers, so the name
DMA buffer was a natural one. However, currently they are used also as
dumb buffers and MOBs backing guest backed objects so renaming them to
buffer objects is logical. Particularly since there is a dmabuf subsystem
in the kernel where a dma buffer means something completely different.

This also renames user-space api structures and IOCTL names
correspondingly, but the old names remain defined for now and the ABI
hasn't changed.

There are a couple of minor style changes to make checkpatch happy.

6a93cea15e drm/vmwgfx: Schedule an fb dirty update after resume
We have had problems displaying fbdev after a resume and as a
workaround we have had to call vmw_fb_refresh(). This has had
a number of unwanted side-effects. The root of the problem was,
however that the coalesced fbdev dirty region was not empty on
the first dirty_mark() after a resume, so a flush was never
scheduled.

Fix this by force scheduling an fbdev flush after resume, and
remove the workaround.

140bcaa23a drm/vmwgfx: Fix black screen and device errors when running without fbdev
When we are running without fbdev, transitioning from the login screen to
X or gnome-shell/wayland will cause a vt switch and the driver will disable
svga mode, losing all modesetting resources. However, the kms atomic state
does not reflect that and may think that a crtc is still turned on, which
will cause device errors when we try to bind an fb to the crtc, and the
screen will remain black.

Fix this by turning off all kms resources before disabling svga mode.

7a9d2001a1 drm/vmwgfx: Convert macro to octal representation

31788ca803 drm/vmwgfx: Work around drm removal of control nodes
vmware tools has a daemon that gets layout information from the GUI and
forwards it to DRM so that the modesetting code can set preferred connector
locations and modes. This daemon was using control nodes but since control
nodes were just removed, make it possible for the daemon to use render- or
primary nodes instead. This is a bit ugly but will allow drm to proceed with
removal of the mostly unused control-node code and allow vmware to proceed
with fixing up automatic layout settings for gnome-shell/wayland.

We bump minor to inform user-space about the api change.

This becomes necessary after the fix: "Work around mode set

regression is they will likely get a black screen after a software

7c20d213dd drm/vmwgfx: Work around mode set failure in 2D VMs
In a low-memory 2D VM, fbdev can take up a large percentage of
available memory, making them unavailable for other DRM clients.

Since we do not take fbdev into account when filtering modes,
we end up claiming to support more modes than we actually do.

As a result, users get a black screen when setting a mode too
large for current available memory.  In a low-memory VM
configuration, users can get a black screen for a mode as low
as 1024x768.

The current mode filtering mechanism keys off of
SVGA_REG_SUGGESTED_GBOBJECT_MEM_SIZE_KB, i.e. the maximum amount
of surface memory we have.  Since this value is a performance
suggestion, not a hard limit, and since there should not be much
of a performance impact for a 2D VM, rather than filtering out
more modes, we will just allow ourselves to exceed the SVGA's
performance suggestion.

Also changed assumed bpp to 32 from 16 to make sure we can
actually support all the modes listed.

Fixes native drm clients like Fedora 23 Wayland which now appears to

Also fixes a couple of ignored error paths.

Since the core drm cursor hotspot is incompatible with the legacy vmwgfx
hotspot (the core drm hotspot is reset when the drm_mode_cursor ioctl
is used), we need to keep track of both and add them when the device
hotspot is set. We assume that either is always zero.

2e586a7e01 drm/vmwgfx: Map the fifo as cached
On the guest kernel side, previously the FIFO has been mapped write-
combined. This has worked since VMs up to now has not honored the mapping
type and mapped the FIFO cached anyway. Since the FIFO is accessed cached
by the CPU on the virtual device side, this leads to inconsistent
mappings once the guest starts to honor the mapping types.

So ask for cached mappings when we map the FIFO. We do this by
using ioremap_cache() instead of ioremap_wc(), and remove the MTRR setup.
On the TTM side, MOBs, GMRs and VRAM buffers are already requesting
cached mappings for kernel- and user-space.

05c9501859 drm/vmwgfx: Fix crash when unloading vmwgfx v2
This patch fixes two issues.  One, when a surface is a proxy for a DMA
buffer, it holds an extra reference that needs to be cleared.

Two, when fbdev is enabled, we need to unpin the framebuffer before
unloading the driver.  This is done by a call to vmw_fb_off().

v2
Moved unreferencing surface to from vmw_framebuffer_surface_destroy()
to vmw_kms_new_framebuffer()

Added "struct vmw_framebuffer *vfb = NULL;" to silence a compiler
warning.

Removed error checking after calling vmw_surface/dmabuf_reference()

a278724aa2 drm/vmwgfx: Implement fbdev on kms v2
With screen targets the old legacy display system fbdev doesn't work
satisfactory anymore. At best the resolution is severely restricted.
Therefore implement fbdev on top of the kms system. With this change, fbdev
will be using whatever KMS backend is chosen.

There are helpers available for this, so in the future we'd probably want
to implement the helper callbacks instead of calling into our KMS
implementation directly.

v2: Make sure we take the mode_config mutex around modesetting,
Also clear the initial framebuffer using vzalloc instead of vmalloc.

496eb6fd2c drm/vmwgfx: Replace the hw mutex with a hw spinlock
Fixes a case where we call vmw_fifo_idle() from within a wait function with
task state !TASK_RUNNING, which is illegal.

In addition, make the locking fine-grained, so that it is performed once
for every read- and write operation. This is of course more costly, but we
don't perform much register access in the timing critical paths anyway. Instead
we have the extra benefit of being sure that we don't forget the hw lock around
register accesses. I think currently the kms code was quite buggy w r t this.

48ba813701 drm: drop redundant drm_file->is_master
The drm_file->is_master field is redundant as it's equivalent to:
    drm_file->master && drm_file->master == drm_file->minor->master

1) "=>"
  Whenever we set drm_file->is_master, we also set:
      drm_file->minor->master = drm_file->master;

  Whenever we clear drm_file->is_master, we also call:
      drm_master_put(&drm_file->minor->master);
  which implicitly clears it to NULL.

2) "<="
  minor->master cannot be set if it is non-NULL. Therefore, it stays as
  is unless a file drops it.

  If minor->master is NULL, it is only set by places that also adjust
  drm_file->is_master.

Therefore, we can safely drop is_master and replace it by an inline helper
that matches:
    drm_file->master && drm_file->master == drm_file->minor->master

6796cb16c0 drm: use anon-inode instead of relying on cdevs
DRM drivers share a common address_space across all character-devices of a
single DRM device. This allows simple buffer eviction and mapping-control.
However, DRM core currently waits for the first ->open() on any char-dev
to mark the underlying inode as backing inode of the device. This delayed
initialization causes ugly conditions all over the place:
  if (dev->dev_mapping)
    do_sth();

To avoid delayed initialization and to stop reusing the inode of the
char-dev, we allocate an anonymous inode for each DRM device and reset
filp->f_mapping to it on ->open().

Bit a bit -fixes pull request in the merge window than usual dua to two
feauture-y things:
- Display CRCs are now enabled on all platforms, including the odd DP case
  on gm45/vlv. Since this is a testing-only feature it should ever hurt,
  but I figured it'll help with regression-testing -fixes. So I left it
  in and didn't postpone it to 3.14.
- Display power well refactoring from Imre. Would have caused major pain
  conflict with the bdw stage 1 patches if I'd postpone this to -next.
  It's only an relatively small interface rework, so shouldn't cause pain.
  It's also been in my tree since almost 3 weeks already.

That accounts for about two thirds of the pull, otherwise just bugfixes:
- vlv backlight fix from Jesse/Jani
- vlv vblank timestamp fix from Jesse
- improved edp detection through vbt from Ville (fixes a vlv issue)
- eDP vdd fix from Paulo
- fixes for dvo lvds on i830M
- a few smaller things all over

Note: This contains a backmerge of v3.12. Since the -internal branch
always applied on top of -nightly I need that unified base to merge bdw
patches. So you'll get a conflict with radeon connector props when pulling
this (and nouveau/master will also conflict a bit when Ben doesn't
rebase). The backmerge itself only had conflicts in drm/i915.

There's also a tiny conflict between Jani's backlight fix and your sysfs
lifetime fix in drm-next.

0faa4a8777 drm/vmwgfx: remove ->firstopen callback
So if we survey kms drivers there's a bunch of things they commonly do
in ->lastclose
- delayed processing of vga switcheroo requests (i915, nouveau,
  radeon)
- force-restoring the fbcon (most)
- resetting a bunch properties to make fbcon work better (omap)
- disabling all outputs (vmwgfx)

In short besides the semantically important vga switcheroo stuff they
all try very hard to keep fbcon working in case X dies.

But none of them try to not do this at driver unload time safe for
vmwgfx, and digging through logs I couldn't find any reason for why
vmwgfx is special.

Since ->firstopen has lots of potential for abuse with kms drivers
(like delaying driver setup to pamper over races in the load sequence)
it's imo very much worth it to remove this logic so that we can
stop using the ->firstopen callback for kms drivers.

Also module unloading is rather a debug feature and developers should
know how to restore the display to a sane configuration.

b0e898ac55 drm: remove FASYNC support
So I've stumbled over drm_fasync and wondered what it does. Digging
that up is quite a story.

First I've had to read up on what this does and ended up being rather
bewildered why peopled loved signals so much back in the days that
they've created SIGIO just for that ...

Then I wondered how this ever works, and what that strange "No-op."
comment right above it should mean. After all calling the core fasync
helper is pretty obviously not a noop. After reading through the
kernels FASYNC implementation I've noticed that signals are only sent
out to the processes attached with FASYNC by calling kill_fasync.

No merged drm driver has ever done that.

After more digging I've found out that the only driver that ever used
this is the so called GAMMA driver. I've frankly never heard of such a
gpu brand ever before. Now FASYNC seems to not have been the only bad
thing with that driver, since Dave Airlie removed it from the drm
driver with prejudice:

commit 1430163b4bbf7b00367ea1066c1c5fe85dbeefed
Author: Dave Airlie <airlied@linux.ie>
Date:   Sun Aug 29 12:04:35 2004 +0000

    Drop GAMMA DRM from a great height ...

Long story short, the drm fasync support seems to be doing absolutely
nothing. And the only user of it was never merged into the upstream
kernel. And we don't need any fops->fasync callback since the fcntl
implementation in the kernel already implements the noop case
correctly.

So stop this particular cargo-cult and rip it all out.

v2: Kill drm_fasync assignments in rcar (newly added) and imx drivers
(somehow I've missed that one in staging). Also drop the reference in
the drm DocBook. ARM compile-fail reported by Rob Clark.

v3: Move the removal of dev->buf_asnyc assignment in drm_setup to this
patch here.

v4: Actually git add ... tsk.

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

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:

be53bfdb80 Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm main changes from Dave Airlie:
 "This is the main drm pull request, I'm probably going to send two more
  smaller ones, will explain below.

  This contains a patch that is also in the fbdev tree, but it should be
  the same patch, it added an API for hot unplugging framebuffer
  devices, and I need that API for a new driver.

  It also contains some changes to the i2c tree which Jean has acked,
  and one change to moorestown platform stuff in x86.

  Highlights:
   - new drivers: UDL driver for USB displaylink devices, kms only,
     should support correct hotplug operations.
   - core: i2c speedups + better hotplug support, EDID overriding via
     firmware interface - allows user to load a firmware for a broken
     monitor/kvm from userspace, it even has documentation for it.
   - exynos: new HDMI audio + hdmi 1.4 + virtual output driver
   - gma500: code cleanup
   - radeon: cleanups, CS optimisations, streamout support and pageflip
     fix
   - nouveau: NVD9 displayport support + more reclocking work
   - i915: re-enabling GMBUS, finish gpu patch (might help hibernation
     who knows), missed irq fixes, stencil tiling fixes, interlaced
     support, aliasesd PPGTT support for SNB/IVB, swizzling for SNB/IVB,
     semaphore fixes

  As well as the usual bunch of cleanups and fixes all over the place.

  I've got two things I'd like to merge a bit later:

   a) AMD support for all their new radeonhd 7000 series GPU and APUs.
      AMD dropped this a bit late due to insane internal review
      processes, (please AMD just follow Intel and let open source guys
      ship stuff early) however I don't want to penalise people who own
      this hardware (since its been on sale for 3-4 months and GPU hw
      doesn't exactly have a lifetime in years) and consign them to
      using closed drivers for longer than necessary.  The changes are
      well contained and just plug into the driver new gpu functionality
      so they should be fairly regression proof.  I just want to give
      them a bit of a run on the hw AMD kindly sent me.

   b) drm prime/dma-buf interface code.  This is just infrastructure
      code to expose the dma-buf stuff to drm drivers and to userspace.
      I'm not planning on pushing any driver support in this cycle
      (except maybe exynos), but I'd like to get the infrastructure code
      in so for the next cycle I can start getting the driver support
      into the individual drivers.  We have started driver support for
      i915, nouveau and udl along with I think exynos and omap in
      staging.  However this code relies on the dma-buf tree being
      pulled into your tree first since it needs the latest interfaces
      from that tree.  I'll push to get that tree sent asap.

  (oh and any warnings you see in i915 are gcc's fault from what anyone
  can see)."

Fix up trivial conflicts in arch/x86/platform/mrst/mrst.c due to the new
msic_thermal_platform_data() thermal function being added next to the
tc35876x_platform_data() i2c device function..

466e69b8b0 drm: move pci bus master enable into driver.
The current enabling of bus mastering in the drm midlayer allows a large
race condition under kexec. When a kexec'ed kernel re-enables bus mastering
for the GPU, previously setup dma blocks may cause writes to random pieces
of memory. On radeon the writeback mechanism can cause these sorts of issues.

This patch doesn't fix the problem, but it moves the bus master enable under
the individual drivers control so they can move enabling it until later in
their load cycle and close the race.

Fix for radeon kms driver will be in a follow-up patch.

e08e96de98 drm: Make the per-driver file_operations struct const
From fdf1fdebaa00f81de18c227f32f8074c8b352d50 Mon Sep 17 00:00:00 2001
From: Arjan van de Ven <arjan@linux.intel.com>
Date: Sun, 30 Oct 2011 19:06:07 -0700
Subject: [PATCH] drm: Make the per-driver file_operations struct const

The DRM layer keeps a copy of struct file_operations inside its
big driver struct... which prevents it from being consistent and static.
For consistency (and the general security objective of having such things
static), it's desirable to get this fixed.

This patch splits out the file_operations field to its own struct,
which is then "static const", and just stick a pointer to this into
the driver struct, making it more consistent with how the rest of the
kernel does this.

cd2b89e7e8 vmwgfx: Reinstate the update_layout ioctl
We need to redefine a connector as "connected" if it matches a window
in the host preferred GUI layout.
Otherwise "smart" window managers would turn on Xorg outputs that we don't
want to be on.

This reinstates the update_layout and adds the following information to
the modesetting system.
a) Connection status <-> Equivalent to real hardware connection status
b) Preferred mode <-> Equivalent to real hardware reading EDID
c) Host window position <-> Equivalent to a real hardware scanout address
dynamic register.

It should be noted that there is no assumption here about what should be
displayed and where. Only how to access the host windows.

This also bumps minor to signal availability of the new IOCTL.

Based on code originally written by Jakob Bornecrantz

e2fa3a7683 vmwgfx: Fix up query processing
Previously, query results could be placed in any buffer object, but since
we didn't allow pinned buffer objects, query results could be written when
that buffer was evicted, corrupting data in other buffers.

Now, require that buffers holding query results are no more than two pages
large, and allow one single pinned such buffer. When the command submission
code encounters query result structures in other buffers, the queries in the
pinned buffer will be finished using a query barrier for the last hardware
context using the buffer. Also if the command submission code detects
that a new hardware context is used for queries, all queries of the previous
hardware context is also flushed. Currently we use waiting for a no-op
occlusion query as a query barrier for a specific context.

The query buffer is also flushed and unpinned on context destructions,
master drops and before scanout bo placement.

No functional change - just cosmetic.

8410ea3b95 drm: rework PCI/platform driver interface.
This abstracts the pci/platform interface out a step further,
we can go further but this is far enough for now to allow USB
to be plugged in.

The drivers now just call the init code directly for their
device type.

135cba0dc3 vmwgfx: Implement a proper GMR eviction mechanism
Use Ben's new range manager hooks to implement a manager for
GMRs that manages ids rather than ranges.
This means we can use the standard TTM code for binding, unbinding and
eviction.

7fbd721ad3 drm/vmwgfx: Add new-style PM hooks to improve hibernation behavior
Add the new-style PM hooks prepare and complete. This allows us to
power up the device again after the hibernation image has been created, and
display output will thus be active until the VM is finally powered off.
