Rob Clark 3ab1c5cc39 drm/msm: Add param for userspace to query suspend count
Performance counts, and ALWAYS_ON counters used for capturing GPU
timestamps, lose their state across suspend/resume cycles.  Userspace
tooling for performance monitoring needs to be aware of this.  For
example, after a suspend userspace needs to recalibrate it's offset
between CPU and GPU time.

amdgpu:
- Debugfs cleanup
- Various cleanups and spelling fixes
- Flexible array cleanups
- Initial AMD Freesync HDMI
- Display fixes
- 10bpc dithering improvements
- Display ASSR support
- Clean up and unify powerplay and swsmu interfaces

- Drop legacy IO BAR requirements
- Various power fixes

amdkfd:
- MMU notifier fixes
- APU fixes

radeon:
- Debugfs cleanups
- Flexible array cleanups

UAPI:
- amdgpu: Add a new INFO ioctl interface to query video capabilities
  rather than hardcoding them in userspace.  This allows us to provide
  fine grained asic capabilities (e.g., if a particular part is
  bandwidth limited, we can limit the capabilities).  Proposed userspace:
  https://gitlab.freedesktop.org/leoliu/drm/-/commits/info_video_caps
  https://gitlab.freedesktop.org/leoliu/mesa/-/commits/info_video_caps
- amdkfd: bump the driver version.  There was a problem with reporting
  some RAS features on older versions of the driver. Proposed userspace:
  7cdd63475c

Danvet: A bunch of conflicts all over, but it seems to compile ... I
did put the call to dc_allow_idle_optimizations() on a single line
since it looked a bit too jarring to be left alone.

Jason Ekstrand b5b6f6a610 drm/i915/gem: Drop legacy execbuffer support (v2)
libdrm has supported the newer execbuffer2 ioctl and using it by default
when it exists since libdrm commit b50964027bef which landed Mar 2, 2010.
The i915 and i965 drivers in Mesa at the time both used libdrm and so
did the Intel X11 back-end.  The SNA back-end for X11 has always used
execbuffer2.

v2 (Jason Ekstrand):
 - Add a comment saying what Linux version it's being removed in.

drm/fourcc: fix Amlogic format modifier masks
The comment says the layout and options use 8 bits, and the shift
uses 8 bits. However the mask is 0xf, ie. 0b00001111 (4 bits).

This could be surprising when introducing new layouts or options
that take more than 4 bits, as this would silently drop the high
bits.

Make the masks consistent with the comment and the shift.

Found when writing a drm_info patch [1].

drm/doc: demote old doc-comments in drm.h
Sphinx doesn't like old doc-comments in drm.h and generates warnings
like:

    ./include/uapi/drm/drm.h:87: warning: cannot understand function prototype: 'struct drm_clip_rect '
    ./include/uapi/drm/drm.h:97: warning: cannot understand function prototype: 'struct drm_drawable_info '
    ./include/uapi/drm/drm.h:105: warning: cannot understand function prototype: 'struct drm_tex_region '
    ...

Demote these to regular comments, because converting all of them is
quite a lot of work (also requires documenting all of the struct fields
for instance). Also many of these structures aren't really used by
modern user-space.

We can easily convert these remaining old comments to Sphinx style on a
one-by-one basis.

Tvrtko Ursulin 348fb0cb0a drm/i915/pmu: Deprecate I915_PMU_LAST and optimize state tracking
Adding any kinds of "last" abi markers is usually a mistake which I
repeated when implementing the PMU because it felt convenient at the time.

This patch marks I915_PMU_LAST as deprecated and stops the internal
implementation using it for sizing the event status bitmask and array.

New way of sizing the fields is a bit less elegant, but it omits reserving
slots for tracking events we are not interested in, and as such saves some
runtime space. Adding sampling events is likely to be a special event and
the new plumbing needed will be easily detected in testing. Existing
asserts against the bitfield and array sizes are keeping the code safe.

First event which gets the new treatment in this new scheme are the
interrupts - which neither needs any tracking in i915 pmu nor needs
waking up the GPU to read it.

v2:
 * Streamline helper names. (Chris)

v3:
 * Comment which events need tracking. (Chris)

The table describes how each bit in the u64 value is used. Explicitly
state which values a field can take if we have defines for them. Also
add a note when a field isn't always populated.

Forcing people to update the table when changing the bit layout should
make it more obvious when there's a mistake, I hope.

If we get to the point where the bit layout gets more complicated, it
might be worth it to split the table into multiple tables (e.g. one for
GFX8, one for GFX9+, and so on).

Bas Nieuwenhuizen 8ba16d5993 drm/fourcc: Add AMD DRM modifiers.
This adds modifiers for GFX9+ AMD GPUs.

As the modifiers need a lot of parameters I split things out in
getters and setters.
  - Advantage: simplifies the code a lot
  - Disadvantage: Makes it harder to check that you're setting all
                  the required fields.

The tiling modes seem to change every generation, but the structure
of what each tiling mode is good for stays really similar. As such
the core of the modifier is
 - the tiling mode
 - a version. Not explicitly a GPU generation, but splitting out
   a new set of tiling equations.

Sometimes one or two tiling modes stay the same and for those we
specify a canonical version.

Then we have a bunch of parameters on how the compression works.
Different HW units have different requirements for these and we
actually have some conflicts here.

e.g. the render backends need a specific alignment but the display
unit only works with unaligned compression surfaces. To work around
that we have a DCC_RETILE option where both an aligned and unaligned
compression surface are allocated and a writer has to sync the
aligned surface to the unaligned surface on handoff.

Finally there are some GPU parameters that participate in the tiling
equations. These are constant for each GPU on the rendering/texturing
side. The display unit is very flexible however and supports all
of them :|

Some estimates:
 - Single GPU, render+texture: ~10 modifiers
 - All possible configs in a gen, display: ~1000 modifiers
 - Configs of actually existing GPUs in a gen: ~100 modifiers

For formats with a single plane everything gets put in a separate
DRM plane. However, this doesn't fit for some YUV formats, so if
the format has >1 plane, we let the driver pack the surfaces into
1 DRM plane per format plane.

This way we avoid X11 rendering onto the frontbuffer with DCC, but
still fit into 4 DRM planes.

drm: deprecate DRM_FORMAT_MOD_NONE
DRM_FORMAT_MOD_NONE is in the list of vendors, which is pretty
confusing. We already have DRM_FORMAT_MOD_VENDOR_NONE. Move it down in
the list of format modifiers.

DRM_FORMAT_MOD_NONE is an alias for DRM_FORMAT_MOD_LINEAR, however the
name is confusing: NONE doesn't mean that the modifier is implicit,
instead it means that the layout is linear. Deprecate it.

Simon Ser ec5722adb8
drm/fourcc: document modifier uniqueness requirements
There have suggestions to bake pitch alignment, address alignment,
contiguous memory or other placement (hidden VRAM, GTT/BAR, etc)
constraints into modifiers. Last time this was brought up it seemed
like the consensus was to not allow this. Document this in drm_fourcc.h.

There are several reasons for this.

- Encoding all of these constraints in the modifiers would explode the
  search space pretty quickly (we only have 64 bits to work with).
- Modifiers need to be unambiguous: a buffer can only have a single
  modifier.
- Modifier users aren't expected to parse modifiers (except drivers).

v2: add paragraph about aliases (Daniel)

v3: fix unrelated changes sent with the patch

v4: disambiguate users between driver and higher-level programs (Brian,
Daniel)

v5: fix AFBC example (Brian, Daniel)

v6: remove duplicated paragraph (Daniel)

Gurchetan Singh eda3e1018f drm/virtgpu api: blob resources
This makes blob resources available to guest userspace. They are needed
for GL4.5, Vulkan and zero-copy virtio-gpu.

For Mesa, blob resources have been tested with Piglit's ARB_buffer_storage
tests and apitraces.  Apitraces of GL4.5 games show we're between 70%
to 80% of host performance on Iris, based on a apitrace of a 2013 GL4.5
game:

11.204 FPS (guest)
15.947 FPS (host)

This is still better than the status quo, when said game was unplayable
with Virgl due to an inefficient GL4.3 fallback.  But there's still room
for improvement if we want to match HW-assisted virtualization.

For Vulkan, blob resources have been tested with dEQP.vk.memory* and
running Vulkan applications in production with the "Cuttlefish" virtual
Android device.  This has been done with Lingfeng Yang's "gfxstream"
Vulkan implementation, which virtualizes Vulkan across many Google
products.
