ce234ccc03 drm/tegra: Changes for v4.18-rc1
This set enables IOMMU support in the gr2d and gr3d drivers and adds
 support for the zpos property on older Tegra generations. It also
 enables scaling filters and incorporates some rework to eliminate a
 private wrapper around struct drm_framebuffer.
 
 The remainder is mostly a random assortment of fixes and cleanups, as
 well as some preparatory work for destaging the userspace ABI, which
 is almost ready and is targetted for v4.19-rc1.

900aa8ad21 drm: Add and handle new aspect ratios in DRM layer
HDMI 2.0/CEA-861-F introduces two new aspect ratios:
- 64:27
- 256:135

This patch:
-  Adds new DRM flags for to represent these new aspect ratios.
-  Adds new cases to handle these aspect ratios while converting
from user->kernel mode or vise versa.

This patch was once reviewed and merged, and later reverted due
to lack of DRM client protection, while adding aspect ratio bits
in user modes. This is a re-spin of the series, with DRM client
cap protection.

7595bda2fb drm: Add DRM client cap for aspect-ratio
To enable aspect-ratio support in DRM, blindly exposing the aspect
ratio information along with mode, can break things in existing
non-atomic user-spaces which have no intention or support to use this
aspect ratio information.

To avoid this, a new drm client cap is required to enable a non-atomic
user-space to advertise if it supports modes with aspect-ratio. Based
on this cap value, the kernel will take a call on exposing the aspect
ratio info in modes or not.

This patch adds the client cap for aspect-ratio.

Since no atomic-userspaces blow up on receiving aspect-ratio
information, the client cap for aspect-ratio is always enabled
for atomic clients.

9913f74fe1 drm/exynos: ipp: Add IPP v2 framework
This patch adds Exynos IPP v2 subsystem and userspace API.

New userspace API is focused ONLY on memory-to-memory image processing.
The two remainging operation modes of obsolete IPP v1 API (framebuffer
writeback and local-path output with image processing) can be implemented
using standard DRM features: writeback connectors and additional DRM planes
with scaling features.

V2 IPP userspace API is based on stateless approach, which much better fits
to memory-to-memory image processing model. It also provides support for
all image formats, which are both already defined in DRM API and supported
by the existing IPP hardware modules.

The API consists of the following ioctls:
- DRM_IOCTL_EXYNOS_IPP_GET_RESOURCES: to enumerate all available image
  processing modules,
- DRM_IOCTL_EXYNOS_IPP_GET_CAPS: to query capabilities and supported image
  formats of given IPP module,
- DRM_IOCTL_EXYNOS_IPP_GET_LIMITS: to query hardware limitiations for
  selected image format of given IPP module,
- DRM_IOCTL_EXYNOS_IPP_COMMIT: to perform operation described by the
  provided structures (source and destination buffers, operation rectangle,
  transformation, etc).

The proposed userspace API is extensible. In the future more advanced image
processing operations can be defined to support for example blending.

Userspace API is fully functional also on DRM render nodes, so it is not
limited to the root/privileged client.

Internal driver API also has been completely rewritten. New IPP core
performs all possible input validation, checks and object life-time
control. The drivers can focus only on writing configuration to hardware
registers. Stateless nature of DRM_IOCTL_EXYNOS_IPP_COMMIT ioctl simplifies
the driver API. Minimal driver needs to provide a single callback for
starting processing and an array with supported image formats.

57692c94dc drm/v3d: Introduce a new DRM driver for Broadcom V3D V3.x+
This driver will be used to support Mesa on the Broadcom 7268 and 7278
platforms.

V3D 3.3 introduces an MMU, which means we no longer need CMA or vc4's
complicated CL/shader validation scheme.  This massively changes the
GEM behavior, so I've forked off to a new driver.

v2: Mark SUBMIT_CL as needing DRM_AUTH.  coccinelle fixes from kbuild
    test robot. Drop personal git link from MAINTAINERS.  Don't
    double-map dma-buf imported BOs.  Add kerneldoc about needing MMU
    eviction.  Drop prime vmap/unmap stubs.  Delay mmap offset setup
    to mmap time.  Use drm_dev_init instead of _alloc.  Use
    ktime_get() for wait_bo timeouts.  Drop drm_can_sleep() usage,
    since we don't modeset.  Switch page tables back to WC (debug
    change to coherent had slipped in).  Switch
    drm_gem_object_unreference_unlocked() to
    drm_gem_object_put_unlocked().  Simplify overflow mem handling by
    not sharing overflow mem between jobs.
v3: no changes
v4: align submit_cl to 64 bits (review by airlied), check zero flags in
    other ioctls.

4c70ac7639 drm/vc4: Add a pad field to align drm_vc4_submit_cl to 64 bits.
I had originally asked Stefan Schake to drop the pad field from the
syncobj changes that just landed, because I couldn't come up with a
reason to align to 64 bits.

Talking with Dave Airlie about the new v3d driver's submit ioctl, we
came up with a reason: sizeof() on 64-bit platforms may align to 64
bits, in which case the userspace will be submitting the aligned size
and the final 32 bits won't be zero-padded by the kernel.  If
userspace doesn't zero-fill, then a future ABI change adding a 32-bit
field at the end could potentially cause the kernel to read undefined
data from old userspace (our userspace happens to use structure
initialization that zero-fills, but as a general rule we try not to
rely on that in the kernel).

c822e05918 drm/i915: expose rcs topology through query uAPI
With the introduction of asymmetric slices in CNL, we cannot rely on
the previous SUBSLICE_MASK getparam to tell userspace what subslices
are available. Here we introduce a more detailed way of querying the
Gen's GPU topology that doesn't aggregate numbers.

This is essential for monitoring parts of the GPU with the OA unit,
because counters need to be normalized to the number of
EUs/subslices/slices. The current aggregated numbers like EU_TOTAL do
not gives us sufficient information.

The Mesa series making use of this API is :

    https://patchwork.freedesktop.org/series/38795/

As a bonus we can draw representations of the GPU :

a446ae2c6e drm/i915: add query uAPI
There are a number of information that are readable from hardware
registers and that we would like to make accessible to userspace. One
particular example is the topology of the execution units (how are
execution units grouped in subslices and slices and also which ones
have been fused off for die recovery).

At the moment the GET_PARAM ioctl covers some basic needs, but
generally is only able to return a single value for each defined
parameter. This is a bit problematic with topology descriptions which
are array/maps of available units.

This change introduces a new ioctl that can deal with requests to fill
structures of potentially variable lengths. The user is expected fill
a query with length fields set at 0 on the first call, the kernel then
sets the length fields to the their expected values. A second call to
the kernel with length fields at their expected values will trigger a
copy of the data to the pointed memory locations.

The scope of this uAPI is only to provide information to userspace,
not to allow configuration of the device.

v2: Simplify dispatcher code iteration (Tvrtko)
    Tweak uapi drm_i915_query_item structure (Tvrtko)

v3: Rename pad fields into flags (Chris)
    Return error on flags field != 0 (Chris)
    Only copy length back to userspace in drm_i915_query_item (Chris)

v4: Use array of functions instead of switch (Chris)

v5: More comments in uapi (Tvrtko)
    Return query item errors in length field (All)

v6: Tweak uapi comments style to match the coding style (Lionel)

v7: Add i915_query.h (Joonas)

v8: (Lionel) Change the behavior of the item iterator to report
    invalid queries into the query item rather than stopping the
    iteration. This enables userspace applications to query newer
    items on older kernels and only have failure on the items that are
    not supported.

v9: Edit copyright headers (Joonas)

v10: Typos & comments in uapi (Joonas)

147ccf931e drm/uapi: Deprecate DRM_MODE_PROP_PENDING
DRM_MODE_PROP_PENDING is not used anywhere (except printed out
by libdrm proptest/modetest).

This seems to be yet another thing blindly copied from xrandr.
Quoting from the protocol spec:
"If 'pending' is TRUE, changes made to property values with
 RRChangeOutputProperty will be saved in the pending property value
 and be automatically copied to the current value on the next
 RRSetCrtcConfig request involving the named output. If 'pending' is
 FALSE, changes are copied immediately."

So it was some kind of early idea for atomic property updates.

65101d8c91 drm/vc4: Expose performance counters to userspace
The V3D engine has various hardware counters which might be interesting
to userspace performance analysis tools.

Expose new ioctls to create/destroy a performance monitor object and
query the counter values of this perfmance monitor.

Note that a perfomance monitor is given an ID that is only valid on the
file descriptor it has been allocated from. A performance monitor can be
attached to a CL submission and the driver will enable HW counters for
this request and update the performance monitor values at the end of the
job.

6ec5bd3489 drm/i915: Deprecate I915_SET_COLORKEY_NONE
Deprecate the silly I915_SET_COLORKEY_NONE flag. The obvious
way to disable colorkey is to just set flags to 0, which is
exactly what the intel ddx has been doing all along.

Currently when userspace sets the flags to 0, we end up in a
funny state where colorkey is disabled, but various colorkey
vs. scaling checks still consider colorkey to be enabled, and
thus we don't allow plane scaling to kick in.

In case there is some other userspace out there that actually
uses this flag (unlikely as this is an i915 specific uapi)
we'll keep on accepting it.

05ebac0980 drm/uapi: Deprecate DRM_MODE_FLAG_BCAST
Reject any mode with DRM_MODE_FLAG_BCAST. We have no code that even
checks for this flag hence it can't possibly do any good.

I think this maybe originated from fbdev where it was supposed to
indicate PAL/NTSC broadcast timings. I have no idea why those would
have to be identified by a flag rather than by just the timings
themselves. And then I assume it got copied into xfree86 for
fbdevhw, and later on it leaked into the randr protocol and kms uapi.

Since kms fbdev emulation never uses the corresponding fbdev flag
there should be no sane way for this to come back into kms via
userspace either.

The bulk of these changes are preparation work and addition of support

 DisplayPort.
 
 Tegra DRM now also uses the atomic commit helpers instead of the open-

 of the Tegra186 support the driver also gained HDMI 2.0 as well as zpos
 property support.

24557865c8 drm: Add Content Protection property
This patch adds a new optional connector property to allow userspace to enable
protection over the content it is displaying. This will typically be implemented
by the driver using HDCP.

The property is a tri-state with the following values:
- OFF: Self explanatory, no content protection
- DESIRED: Userspace requests that the driver enable protection
- ENABLED: Once the driver has authenticated the link, it sets this value

The driver is responsible for downgrading ENABLED to DESIRED if the link becomes
unprotected. The driver should also maintain the desiredness of protection
across hotplug/dpms/suspend.

If this looks familiar, I posted [1] this 3 years ago. We have been using this
in ChromeOS across exynos, mediatek, and rockchip over that time.

Changes in v2:
 - Pimp kerneldoc for content_protection_property (Daniel)
 - Drop sysfs attribute
Changes in v3:
 - None
Changes in v4:
- Changed kerneldoc to recommend userspace polling (Daniel)
- Changed kerneldoc to briefly describe how to attach the property (Daniel)
Changes in v5:
- checkpatch whitespace noise
- Change DRM_MODE_CONTENT_PROTECTION_OFF to DRM_MODE_CONTENT_PROTECTION_UNDESIRED
Changes in v6:
- None

8ded59413c drm/exynos: ipp: Remove Exynos DRM IPP subsystem
Exynos DRM IPP subsystem is in fact non-functional and frankly speaking
dead-code. This patch clearly marks that Exynos DRM IPP subsystem is
broken and never really functional. It will be replaced by a completely
rewritten API.

Exynos DRM IPP user-space API can be obsoleted for the following
reasons:

1. Exynos DRM IPP user-space API can be optional in Exynos DRM, so
userspace should not rely that it is always available and should have
a software fallback in case it is not there.

2. The only mode which was initially semi-working was memory-to-memory
image processing. The remaining modes (LCD-"writeback" and "output")
were never operational due to missing code (both in mainline and even
vendor kernels).

3. Exynos DRM IPP mainline user-space API compatibility for
memory-to-memory got broken very early by commit 083500baef ("drm:
remove DRM_FORMAT_NV12MT", which removed the support for tiled formats,
the main feature which made this API somehow useful on Exynos platforms
(video codec that time produced only tiled frames, to implement xvideo
or any other video overlay, one has to de-tile them for proper
display).

4. Broken drivers. Especially once support for IOMMU has been added,
it revealed that drivers don't configure DMA operations properly and in
many cases operate outside the provided buffers trashing memory around.

5. Need for external patches. Although IPP user-space API has been used
in some vendor kernels, but in such cases there were additional patches
applied (like reverting mentioned 083500baef patch) what means that
those userspace apps which might use it, still won't work with the
mainline kernel version.

We don't have time machines, so we cannot change it, but Exynos DRM IPP
extension should never have been merged to mainline in that form.

Exynos IPP subsystem and user-space API will be rewritten, so remove
current IPP core code and mark existing drivers as BROKEN.

268892cb63 drm/tegra: Sanitize format modifiers
The existing format modifier definitions were merged prematurely, and
recent work has unveiled that the definitions are suboptimal in several
ways:

  - The format specifiers, except for one, are not Tegra specific, but
    the names don't reflect that.
  - The number space is split into two, reserving 32 bits for some
    "parameter" which most of the modifiers are not going to have.
  - Symbolic names for the modifiers are not using the standard
    DRM_FORMAT_MOD_* prefix, which makes them awkward to use.
  - The vendor prefix NV is somewhat ambiguous.

Fortunately, nobody's started using these modifiers, so we can still fix
the above issues. Do so by using the standard prefix. Also, remove TEGRA
from the name of those modifiers that exist on NVIDIA GPUs as well. In
case of the block linear modifiers, make the "parameter" smaller (4
bits, though only 6 values are valid) and don't let that leak into any
of the other modifiers.

Finally, also use the more canonical NVIDIA instead of the ambiguous NV
prefix.
