The magic switching between proper pci driver and shadow-attach isn't
useful anymore since there's no ums+kms drivers left. Let's split this
up properly, calling pci_register_driver for kms drivers and renaming
the shadow-attach init to drm_legacy_pci_init/exit.

The previous attempt at this had an issue with with num_clips > 1
because it would always end up using the coordinates of the last
clip while using width and height calculated from the bounding
box of all the clips.
So if the last clip happens to be not at the top-left corner of
the bounding box, the CPU blit operation would go out of bounds.
The original intent was to coalesce all the clips into one blit,
and to do that we need to also track the starting point of the

Backmerge tag 'v4.11-rc6' into drm-next

drm-misc needs 4.11-rc5, may as well fix conflicts with rc6.
I've broken this by removing the backoff handling from the
set_config2atomic helper in

Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date: Wed Mar 22 22:50:58 2017 +0100
drm/atomic-helper: Remove the backoff hack from set_config
Fixing this properly would mean we get to wire the acquire_ctx all the
way through vmwgfx fbdev code, and doing the same was tricky for the
shared fbdev layer. Probably much better to look into refactoring the
entire code to use the helpers, but since that's not a viable
long-term solution fix the issue by open-coding a vmwgfx version of
set_config, that does the legacy backoff dance internally.
Note: Just compile-tested. The idea is to take
drm_mode_set_config_internal(), remove the "is this a legacy driver"
check, and whack the drm_atomic_legacy_backoff trickery at the end.
Since drm_atomic_legacy_backoff is for atomic commits only we need to
open-code it.

Atomic helpers really want this instead of the hacked-up legacy

own private drm_modeset_locks.
Aside: There's a few atomic drivers (nv50, vc4, soon vmwgfx) which
don't yet use the new atomic color mgmt/gamma table stuff. Would be
nice if they could switch over and just hook up
drm_atomic_helper_legacy_gamma_set() instead.

Most of the display servers today use a single surface to represent the
entire desktop even if it's stretched across multiple screens.
For vmwgfx with STDU, the maximum surface size is limited to the
maximum texture size on the host. On a 2D VM, this limits our
ability to support configurations with more than one 4K monitor.
To get past this limitation, we will now allow using a large DMA buf
as the framebuffer, and take care of blitting contents from this DMA buf
to the display buffer.

In vmw_get_cap_3d_ioctl(), a user can supply 0 for a size that is
used in vzalloc(). This eventually calls dump_stack() (in warn_alloc()),

Merge tag 'doc-4.11-images' of git://git.lwn.net/linux into drm-misc-next
Pointer for Markus's image conversion work.
We need this so we can merge all the pretty drm graphs for 4.12.
Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
First slice of drm-misc-next for 4.12:
Core/subsystem-wide:
- link status core patch from Manasi, for signalling link train fail
to userspace. I also had the i915 patch in here, but that had a
small buglet in our CI, so reverted.
- more debugfs_remove removal from Noralf, almost there now (Noralf
said he'll try to follow up with the stragglers).
- drm todo moved into kerneldoc, for better visibility (see
Documentation/gpu/todo.rst), lots of starter tasks in there.
- devm_ of helpers + use it in sti (from Ben Gaignard, acked by Rob
Herring)
- extended framebuffer fbdev support (for fbdev flipping), and vblank
wait ioctl fbdev support (Maxime Ripard)
- misc small things all over, as usual
- add vblank callbacks to drm_crtc_funcs, plus make lots of good use
of this to simplify drivers (Shawn Guo)
- new atomic iterator macros to unconfuse old vs. new state
Small drivers:
- vc4 improvements from Eric
- vc4 kerneldocs (Eric)!
- tons of improvements for dw-mipi-dsi in rockchip from John Keeping
and Chris Zhong.
- MAINTAINERS entries for drivers managed in drm-misc. It's not yet
official, still an experiment, but definitely not complete fail and
better to avoid confusion. We kinda screwed that up with drm-misc a
bit when we started committers last year.
- qxl atomic conversion (Gabriel Krisman)
- bunch of virtual driver polish (qxl, virgl, ...)
- misc tiny patches all over
This is the first time we've done the same merge-window blackout for
drm-misc as we've done for drm-intel for ages, hence why we have a
_lot_ of stuff queued already. But it's still only half of drm-intel
(room to grow!), and the drivers in drm-misc experiment seems to work
at least insofar as that you also get lots of driver updates here
alredy.

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.

The drm_mm range manager claimed to support top-down insertion, but it
was neither searching for the top-most hole that could fit the
allocation request nor fitting the request to the hole correctly.
In order to search the range efficiently, we create a secondary index
for the holes using either their size or their address. This index
allows us to find the smallest hole or the hole at the bottom or top of
the range efficiently, whilst keeping the hole stack to rapidly service
evictions.
v2: Search for holes both high and low. Rename flags to mode.
v3: Discover rb_entry_safe() and use it!

Currently the pitch is passed in as depth. This causes

The wrong pixel format will be rejected by vmw_kms_new_framebuffer(),

<drm/drm_crtc.h> used to define most of the in-kernel KMS API. It has
now been split into separate files for each object type, but still
includes most other KMS headers to avoid breaking driver compilation.
As a step towards fixing that problem, remove the inclusion of
<drm/drm_encoder.h> from <drm/drm_crtc.h> and include it instead where
appropriate. Also remove the forward declarations of the drm_encoder and
drm_encoder_helper_funcs structures from <drm/drm_crtc.h> as they're not
needed in the header.
<drm/drm_encoder.h> now has to include <drm/drm_mode.h> and contain a
forward declaration of struct drm_encoder in order to allow including it
as the first header in a compilation unit.

The function's behaviour was changed in 90844f0004, without changing
its signature, causing people to keep using it the old way without
realising they were now leaking memory.
Rob Clark also noticed it was also allocating GFP_KERNEL memory in
atomic contexts, breaking them.
Instead of having to allocate GFP_ATOMIC memory and fixing the callers
to make them cleanup the memory afterwards, let's change the function's
signature by having the caller take care of the memory and passing it to
the function.
The new parameter is a single-field struct in order to enforce the size
of its buffer and help callers to correctly manage their memory.

The driver is the last users of the drm_fb_get_bpp_depth() function. It
should ideally be converted to use struct drm_mode_fb_cmd2 instead of
the legacy struct drm_mode_fb_cmd internally, but that will require
broad changes across the code base. As a first step, replace
drm_fb_get_bpp_depth() with drm_format_info() in order to stop exporting
the function to drivers.
The new DRM_ERROR() message comes from the vmw_create_dmabuf_proxy(),
vmw_kms_new_framebuffer_surface() and vmw_kms_new_framebuffer_dmabuf()
functions that currently print an error if the pixel format is
unsupported.

I find that the developers often just specified the numeric value
when calling a macro which is defined with a parameter for access
permission.
As we know, these numeric value for access permission have had the
corresponding macro, and that using macro can improve the robustness and

with the macro.

It would be great if vmwgfx could switch over to the fbdev emulation

Linux 4.7-rc5
The fsl-dcu pull needs -rc3 so go to -rc5 for now.
When the surface backing a framebuffer doesn't match the framebuffer's
dimensions, the screen target code would test the framebuffer dimensions
rather than the surface dimensions when deciding whether to bind the
surface as a screen target directly. This causes a screen target -
surface dimension mismatch and a subsequent device error.
Fix this by testing against the surface dimension.

For the Screen Object display unit, we need to reserve a
guest-invisible region equal to the size of the framebuffer for
the host. This region can only be reserved in VRAM, whereas
the guest-visible framebuffer can be reserved in either VRAM or
GMR.
As such priority should be given to the guest-invisible
region otherwise in a limited VRAM situation, we can fail to
allocate this region.
This patch makes it so that vmw_sou_backing_alloc() is called
before the framebuffer is pinned.

This is the last patch of a 3-patch series to fix console black
screen issue on Ubuntu 16.04 server
In certain scenarios, e.g. when fbdev is enabled, we can get into
a situation where a vmw_framebuffer_pin() is called on a buffer
that is already pinned.
When this happens, ttm_bo_validate() will unintentially remove the
TTM_PL_FLAG_NO_EVICT flag, thus unpinning it, and leaving no way
to actually pin the buffer again.
To prevent this, if a buffer is already pinned, then instead of
calling ttm_bo_validate(), just make sure the proposed placement is
compatible with the existing placement.

This is the 2nd patch in a 3-patch series to fix a console black
screen issue on Ubuntu 16.04 server. This fixes a BUG_ON()
condition where a pinned buffer gets accidentally put onto the
LRU list.
Offer an option for advanced users who want larger modes at 16bpp.
This becomes necessary after the fix: "Work around mode set
failure in 2D VMs." Without this patch, there would be no way
for existing advanced users to get to a high res mode, and the
regression is they will likely get a black screen after a software
update on their current VM.

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.

drivers/gpu/drm/vmwgfx/vmwgfx_msg.o: warning: objtool: vmw_host_get_guestinfo()+0x252: duplicate frame pointer save
To quote Linus:
"The reason is that VMW_PORT_HB_OUT() uses a magic instruction sequence
(a "rep outsb") to communicate with the hypervisor (it's a virtual GPU
driver for vmware), and %rbp is part of the communication. So the
inline asm does a save-and-restore of the frame pointer around the
instruction sequence.
I actually find the objtool warning to be quite reasonable, so it's
not exactly a false positive, since in this case it actually does
point out that the frame pointer won't be reliable over that
instruction sequence.
But in this particular case it just ends up being the wrong thing -
the code is what it is, and %rbp just can't have the frame information
due to annoying magic calling conventions."
Silence the warnings by telling objtool to ignore the two functions
which use the VMW_PORT_HB_{IN,OUT} macros.

Fence contexts are created on the fly (for example) by the GPU scheduler used
in the amdgpu driver as a result of an userspace request. Because of this
userspace could in theory force a wrap around of the 32bit context number
if it doesn't behave well.
Avoid this by increasing the context number to 64bits. This way even when
userspace manages to allocate a billion contexts per second it takes more
than 500 years for the context number to wrap around.

When the framebuffer is a vmwgfx dma buffer and a proxy surface is
created, the vmw_kms_update_proxy() function requires that the proxy
surface width and the framebuffer pitch are compatible, otherwise
display corruption occurs as seen in gnome-shell/native with software
3D. Since the framebuffer pitch is determined by user-space, allocate
a proxy surface the width of which is based on the framebuffer pitch

Fixes native drm clients like Fedora 23 Wayland which now appears to
be able to use cursor hotspots without strange cursor offsets.
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.

drm/vmwgfx: Stabilize the command buffer submission code
This commit addresses some stability problems with the command buffer
submission code recently introduced:
1) Make the vmw_cmdbuf_man_process() function handle reruns internally to
avoid losing interrupts if the caller forgets to rerun on -EAGAIN.
2) Handle default command buffer allocations using inline command buffers.
This avoids rare allocation deadlocks.
3) In case of command buffer errors we might lose fence submissions.
Therefore send a new fence after each command buffer error. This will help
avoid lengthy fence waits.

Just one special case (since i915 lost its ums code, yay):
- radeon: Has slots for the old ums ioctls which don't have
DRM_UNLOCKED, but all filled with drm_invalid_op. So ok to drop it
everywhere.
Every other kms driver just has DRM_UNLOCKED for all their ioctls, as
they should.
v2: admgpu happened, include that one too. And i915 lost its UMS
support which means we can change all the i915 ioctls too.
v3: Rebased on top of new vmwgfx DX interface extensions.
v4: Rebase on top of render-node support in exynos.

This continues the pattern started in commit cc1ef118fc ("drm/irq:
Make pipe unsigned and name consistent"). This is applied to the public
APIs and driver callbacks, so pretty much all drivers need to be updated
to match the new prototypes.

A single commit to fix a command submission hang regression.

drm/vmwgfx: Fix a command submission hang regression
When we're out of command buffer space, we turn on the command buffer
processed irq without re-checking for finished command buffers afterwards.
This might lead to a missed irq and the command submission process waiting
forever for space.
Fix this by rerunning the command buffer submission handler whenever we're
out of command space. This ensures both that we don't needlessly turn on
the irq, and that if we decide to turn on the irq, we recheck for finished
command buffers before going to sleep.

ioremap_cache() is currently not available on some architectures.
Reported-by: kbuild test robot <fengguang.wu@intel.com>
Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com>
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.

If user space calls unreference on a user_dmabuf it will typically
kill the struct ttm_base_object member which is responsible for the
user-space visibility. However the dmabuf part may still be alive and
refcounted. In some situations, like for shared guest-backed surface
referencing/opening, the driver may try to reference the
struct ttm_base_object member again, causing an immediate kernel warning
and a later kernel NULL pointer dereference.
Fix this by always maintaining a reference on the struct
ttm_base_object member, in situations where it might subsequently be
referenced.

Also there is an implementation of register-driven command buffers, that
overrides the FIFO ring for command processing. It's needed for our upcoming

This addresses two issues that cause problems with viewperf maya-03 in
situation with memory pressure.
The first issue causes attempts to unreserve buffers if batched
reservation fails due to, for example, a signal pending. While previously
the ttm_eu api was resistant against this type of error, it is no longer
and the lockdep code will complain about attempting to unreserve buffers
that are not reserved. The issue is resolved by avoid calling
ttm_eu_backoff_reservation in the buffer reserve error path.
The second issue is that the binding_mutex may be held when user-space
fence objects are created and hence during memory reclaims. This may cause
recursive attempts to grab the binding mutex. The issue is resolved by not
holding the binding mutex across fence creation and submission.
