6619ccf1bb dma-buf: Use struct dma_buf_map in dma_buf_vmap() interfaces
This patch updates dma_buf_vmap() and dma-buf's vmap callback to use
struct dma_buf_map.

The interfaces used to return a buffer address. This address now gets
stored in an instance of the structure that is given as an additional
argument. The functions return an errno code on errors.

Users of the functions are updated accordingly. This is only an interface
change. It is currently expected that dma-buf memory can be accessed with
system memory load/store operations.

v3:
	* update fastrpc driver (kernel test robot)
v2:
	* always clear map parameter in dma_buf_vmap() (Daniel)
	* include dma-buf-heaps and i915 selftests (kernel test robot)

91d0ca3d6b Merge tag 'drm-msm-next-2020-09-27' of https://gitlab.freedesktop.org/drm/msm into drm-next
* DSI support for sm8150/sm8250
* Support for per-process GPU pagetables (finally!) for a6xx.
  There are still some iommu/arm-smmu changes required to
  enable, without which it will fallback to the current single
  pgtable state.  The first part (ie. what doesn't depend on
  drm side patches) is queued up for v5.10[1].
* DisplayPort support.  Userspace DP compliance tool support
  is already merged in IGT[2]
* The usual assortment of smaller fixes/cleanups

d693def4fd drm: Remove obsolete GEM and PRIME callbacks from struct drm_driver
Several GEM and PRIME callbacks have been deprecated in favor of
per-instance GEM object functions. Remove the callbacks as they are
now unused. The only exception is .gem_prime_mmap, which is still
in use by several drivers.

What is also gone is gem_vm_ops in struct drm_driver. All drivers now
use struct drm_gem_object_funcs.vm_ops instead.

While at it, the patch also improves error handling around calls
to .free and .get_sg_table callbacks.

v3:
	* restore default call to drm_gem_prime_export() in
	  drm_gem_prime_handle_to_fd()
	* return -ENOSYS if get_sg_table is not set
	* drop all checks for obj->funcs
	* clean up TODO list and documentation
v2:
	* update related TODO item (Sam)

9e9f605fb5 drm/doc: Document that modifiers are always required for fb
Even for legacy userspace, since otherwise GETFB2 is broken and if you
switch between modifier-less and modifier-aware compositors, smooth
transitions break.

Also it's just best practice to make sure modifiers are invariant for
a given drm_fb, and that a modifier-aware kms drivers only has one
place to store them, ignoring any old implicit bo flags or whatever
else might float around.

Motivated by some irc discussion with Bas about amdgpu modifier
support.

db9c1734ad drm/ttm: stop dangerous caching attribute change
When we swapout/in a BO we try to change the caching
attributes of the pages before/after doing the copy.

On x86 this is done by calling set_pages_uc(),
set_memory_wc() or set_pages_wb() for not highmem pages
to update the linear mapping of the page.

On all other platforms we do exactly nothing.

Now on x86 this is unnecessary because copy_highpage() will
either create a temporary mapping of the page which is wb
anyway and destroyed immediately again or use the linear
mapping with the correct caching attributes.

So stop this nonsense and just keep the caching as it is and
return an error when a driver tries to change the caching of
an already populated TT object.

This is much more defensive since changing caching
attributes is platform and driver specific and usually
doesn't work after the page was initially allocated.

4c8e84b887 drm/managed: Cleanup of unused functions and polishing docs
Following functions are only used internally, not by drivers:
- devm_drm_dev_init

Also, now that we have a very slick and polished way to allocate a
drm_device with devm_drm_dev_alloc, update all the docs to reflect the
new reality. Mostly this consists of deleting old and misleading
hints. Two main ones:

- it is no longer required that the drm_device base class is first in
  the structure. devm_drm_dev_alloc can cope with it being anywhere

- obviously embedded now strongly recommends using devm_drm_dev_alloc

v2: Fix typos (Noralf)

v3: Split out the removal of drm_dev_init, that's blocked on some
discussions on how to convert vgem/vkms/i915-selftests. Adjust commit

9ab57658a6 drm/i915: Fix sha_text population code
This patch fixes a few bugs:

1- We weren't taking into account sha_leftovers when adding multiple
   ksvs to sha_text. As such, we were or'ing the end of ksv[j - 1] with
   the beginning of ksv[j]

2- In the sha_leftovers == 2 and sha_leftovers == 3 case, bstatus was
   being placed on the wrong half of sha_text, overlapping the leftover
   ksv value

3- In the sha_leftovers == 2 case, we need to manually terminate the
   byte stream with 0x80 since the hardware doesn't have enough room to
   add it after writing M0

The upside is that all of the HDCP supported HDMI repeaters I could
find on Amazon just strip HDCP anyways, so it turns out to be _really_
hard to hit any of these cases without an MST hub, which is not (yet)
supported. Oh, and the sha_leftovers == 1 case works perfectly!

8445e2c54c drm: Replace mode->export_head with a boolean
In order to shrink drm_display_mode below the magic two cacheline
mark in 64bit we need to shrink it by another 8 bytes. The easiest
thing to eliminate is the 'export_head' list head which is only
used during the getconnector ioctl to temporarly track which modes
on the connector's mode list are to be exposed and which are to
remain hidden.

We can simply replace the list head with a boolean which we use
to tag the modes that are to be exposed. If we make sure to clear
the tags after we're done with them we don't even need an extra
loop over the modes to reset the tags at the start of the
getconnector ioctl.

Conveniently we already have a hole for the boolean left
behind by the removal of mode->private_flags. The final size
of the struct is now 112 bytes on 32bit and 120 bytes on 64bit.

Another alternative would be a temp bitmask so we wouldn't have
to have anything in the mode struct itself. The main issue is
how large of a bitmask do we need? I guess we could allocate
it dynamically but that means an extra kcalloc() and an extra
loop through the modes to count them first (or grow the bitmask
with krealloc() as needed).

1f0882214f drm/i915: Fix sha_text population code
This patch fixes a few bugs:

1- We weren't taking into account sha_leftovers when adding multiple
   ksvs to sha_text. As such, we were or'ing the end of ksv[j - 1] with
   the beginning of ksv[j]

2- In the sha_leftovers == 2 and sha_leftovers == 3 case, bstatus was
   being placed on the wrong half of sha_text, overlapping the leftover
   ksv value

3- In the sha_leftovers == 2 case, we need to manually terminate the
   byte stream with 0x80 since the hardware doesn't have enough room to
   add it after writing M0

The upside is that all of the HDCP supported HDMI repeaters I could
find on Amazon just strip HDCP anyways, so it turns out to be _really_
hard to hit any of these cases without an MST hub, which is not (yet)
supported. Oh, and the sha_leftovers == 1 case works perfectly!

b9936121d9 drm/i915/dp: Extract drm_dp_read_dpcd_caps()
Since DP 1.3, it's been possible for DP receivers to specify an
additional set of DPCD capabilities, which can take precedence over the
capabilities reported at DP_DPCD_REV.

Basically any device supporting DP is going to need to read these in an
identical manner, in particular nouveau, so let's go ahead and just move
this code out of i915 into a shared DRM DP helper that we can use in
other drivers.

v2:
* Remove redundant dpcd[DP_DPCD_REV] == 0 check
* Fix drm_dp_dpcd_read() ret checks

* Fix drm_dp_dpcd_readb() ret check
* Add back comment and move back sink_count assignment in intel_dp_get_dpcd()
v5:
* Change name from drm_dp_get_sink_count() to drm_dp_read_sink_count()

693c3ec597 drm/i915/dp: Extract drm_dp_read_sink_count_cap()
Since other drivers are also going to need to be aware of the sink count
in order to do proper dongle detection, we might as well steal i915's
DP_SINK_COUNT helpers and move them into DRM helpers so that other
dirvers can use them as well.

Note that this also starts using intel_dp_has_sink_count() in
intel_dp_detect_dpcd(), which is a functional change.

3d3721ccb1 drm/i915/dp: Extract drm_dp_read_downstream_info()
We're going to be doing the same probing process in nouveau for
determining downstream DP port capabilities, so let's deduplicate the
work by moving i915's code for handling this into a shared helper:
drm_dp_read_downstream_info().

Note that when we do this, we also do make some functional changes while
we're at it:
* We always clear the downstream port info before trying to read it,
  just to make things easier for the caller
* We skip reading downstream port info if the DPCD indicates that we
  don't support downstream port info
* We only read as many bytes as needed for the reported number of
  downstream ports, no sense in reading the whole thing every time

v2:
* Fixup logic for calculating the downstream port length to account for
  the fact that downstream port caps can be either 1 byte or 4 bytes
  long. We can actually skip fixing the max_clock/max_bpc helpers here
  since they all check for DP_DETAILED_CAP_INFO_AVAILABLE anyway.
* Fix ret code check for drm_dp_dpcd_read
v5:
* Change name from drm_dp_downstream_read_info() to
  drm_dp_read_downstream_info()
* Also, add "See Also" sections for the various downstream info
  functions (drm_dp_read_downstream_info(), drm_dp_downstream_max_clock(),
  drm_dp_downstream_max_bpc())

77ef38574b drm/modeset-lock: Take the modeset BKL for legacy drivers
This fell off in the conversion in

commit 9bcaa3fe58
Author: Michal Orzel <michalorzel.eng@gmail.com>
Date:   Tue Apr 28 19:10:04 2020 +0200

    drm: Replace drm_modeset_lock/unlock_all with DRM_MODESET_LOCK_ALL_* helpers

but it's caught by the drm_warn_on_modeset_not_all_locked() that the
legacy modeset code uses. Since this is the bkl and it's unclear
what's all protected, play it safe and grab it again for legacy
drivers.

Unfortunately this means we need to sprinkle a few more #includes
around.

Also we need to add the drm_device as a parameter to the _END macro.

Finally remove the mute_lock() from setcrtc, since that's now done by
the macro.

e5b9277328 drm: report dp downstream port type as a subconnector property
Currently, downstream port type is only reported in debugfs. This
information should be considered important since it reflects the actual
physical connector type. Some userspace (e.g. window compositors)
may want to show this info to a user.

The 'subconnector' property is already utilized for DVI-I and TV-out for
reporting connector subtype.

The initial motivation for this feature came from i2c test [1].
It is supposed to be skipped on VGA connectors, but it cannot
detect VGA over DP and fails instead.

v2:
 - Ville: utilized drm_dp_is_branch()
 - Ville: implement DP 1.0 downstream type info
 - Replaced create_dp_properties with add_dp_subconnector_property
 - Added dp_set_subconnector_property helper

v4:
 - Ville: add DP1.0 best assumption about subconnector
 - Ville: assume DVI is DVI-D
 - Ville: reuse Writeback enum value for Virtual subconnector
 - Renamed #defines: HDMI -> HDMIA, DP -> DisplayPort

v5: rebase

v6:
 - Jani Nikula: renamed a function name
 - Jani Nikula: addressed the issues with documentation

 "New xilinx displayport driver, AMD support for two new GPUs (more

2a1658bf92 drm/drm_fb_helper: fix fbdev with sparc64
Recent kernels have been reported to panic using the bochs_drm
framebuffer under qemu-system-sparc64 which was bisected to
commit 7a0483ac4f ("drm/bochs: switch to generic drm fbdev emulation").

The backtrace indicates that the shadow framebuffer copy in
drm_fb_helper_dirty_blit_real() is trying to access the real
framebuffer using a virtual address rather than use an IO access
typically implemented using a physical (ASI_PHYS) access on SPARC.

The fix is to replace the memcpy with memcpy_toio() from io.h.

memcpy_toio() uses writeb() where the original fbdev code
used sbus_memcpy_toio(). The latter uses sbus_writeb().

The difference between writeb() and sbus_memcpy_toio() is
that writeb() writes bytes in little-endian, where sbus_writeb() writes
bytes in big-endian. As endian does not matter for byte writes they are
the same. So we can safely use memcpy_toio() here.

Note that this only fixes bochs, in general fbdev helpers still have
issues with mixing up system memory and __iomem space. Fixing that will
require a lot more work.

v3:
  - Improved changelog (Daniel)
  - Added FIXME to fbdev_use_iomem (Daniel)

v2:
  - Added missing __iomem cast (kernel test robot)
  - Made changelog readable and fix typos (Mark)
  - Add flag to select iomem - and set it in the bochs driver

a5f23a7235 drm/vram-helper: Managed vram helpers
Calling drmm_vram_helper_init() sets up a managed instance of
VRAM MM. Releasing the DRM device also frees the memory manager.

The patch also updates the DRM documentation for VRAM helpers. The
tutorial now describes the new managed interface. The old interfaces
are deprecated and should not be used in new code.

5e6c2b4f91 drm/vblank: Add vblank works
Add some kind of vblank workers. The interface is similar to regular
delayed works, and is mostly based off kthread_work. It allows for
scheduling delayed works that execute once a particular vblank sequence
has passed. It also allows for accurate flushing of scheduled vblank
works - in that flushing waits for both the vblank sequence and job
execution to complete, or for the work to get cancelled - whichever
comes first.

Whatever hardware programming we do in the work must be fast (must at
least complete during the vblank or scanout period, sometimes during the
first few scanlines of the vblank). As such we use a high-priority
per-CRTC thread to accomplish this.

Changes since v7:
* Stuff drm_vblank_internal.h and drm_vblank_work_internal.h contents
  into drm_internal.h
* Get rid of unnecessary spinlock in drm_crtc_vblank_on()
* Remove !vblank->worker check
* Grab vbl_lock in drm_vblank_work_schedule()
* Mention self-rearming work items in drm_vblank_work_schedule() kdocs
* Return 1 from drm_vblank_work_schedule() if the work was scheduled
  successfully, 0 or error code otherwise
* Use drm_dbg_core() instead of DRM_DEV_ERROR() in
  drm_vblank_work_schedule()
* Remove vblank->worker checks in drm_vblank_destroy_worker() and
  drm_vblank_flush_worker()
Changes since v6:
* Get rid of ->pending and seqcounts, and implement flushing through
  simpler means - danvet
* Get rid of work_lock, just use drm_device->event_lock
* Move drm_vblank_work item cleanup into drm_crtc_vblank_off() so that
  we ensure that all vblank work has finished before disabling vblanks
* Add checks into drm_crtc_vblank_reset() so we yell if it gets called
  while there's vblank workers active
* Grab event_lock in both drm_crtc_vblank_on()/drm_crtc_vblank_off(),
  the main reason for this is so that other threads calling
  drm_vblank_work_schedule() are blocked from attempting to schedule
  while we're in the middle of enabling/disabling vblanks.
* Move drm_handle_vblank_works() call below drm_handle_vblank_events()
* Simplify drm_vblank_work_cancel_sync()
* Fix drm_vblank_work_cancel_sync() documentation
* Move wake_up_all() calls out of spinlock where we can. The only one I
  left was the call to wake_up_all() in drm_vblank_handle_works() as
  this seemed like it made more sense just living in that function
  (which is all technically under lock)
* Move drm_vblank_work related functions into their own source files
* Add drm_vblank_internal.h so we can export some functions we don't
  want drivers using, but that we do need to use in drm_vblank_work.c
* Add a bunch of documentation
Changes since v4:
* Get rid of kthread interfaces we tried adding and move all of the
  locking into drm_vblank.c. For implementing drm_vblank_work_flush(),
  we now use a wait_queue and sequence counters in order to
  differentiate between multiple work item executions.
* Get rid of drm_vblank_work_cancel() - this would have been pretty
  difficult to actually reimplement and it occurred to me that neither
  nouveau or i915 are even planning to use this function. Since there's
  also no async cancel function for most of the work interfaces in the
  kernel, it seems a bit unnecessary anyway.
* Get rid of to_drm_vblank_work() since we now are also able to just
  pass the struct drm_vblank_work to work item callbacks anyway
Changes since v3:
* Use our own spinlocks, don't integrate so tightly with kthread_works
Changes since v2:
* Use kthread_workers instead of reinventing the wheel.

display-only driver.

1c26b8e090 drm/probe_helper: Add drm_connector_helper_funcs.mode_valid_ctx
This is just an atomic version of mode_valid, which is intended to be
used for situations where a driver might need to check the atomic state
of objects other than the connector itself. One such example is with
MST, where the maximum possible bandwidth on a connector can change
dynamically irregardless of the display configuration.

Changes since v1:
* Use new drm logging functions
* Make some corrections in the mode_valid_ctx kdoc
* Return error codes or 0 from ->mode_valid_ctx() on fail, and store the
  drm_mode_status in an additional function parameter
Changes since v2:
* Don't accidentally assign ret to mode->status on success, or we'll
  squash legitimate mode validation results
* Don't forget to assign MODE_OK to status in drm_connector_mode_valid()
  if we have no callbacks
* Drop leftover hunk in drm_modes.h around enum drm_mode_status
Changes since v3:
* s/return ret/return 0/ in drm_mode_validate_pipeline()
* Minor cleanup in drm_connector_mode_valid()

5186421cbf drm: Introduce epoch counter to drm_connector
This counter will be used by drm_helper_probe_detect caller to determine
if anything had changed(including edid, connection status and etc).
Hardware specific driver detect hooks are responsible for updating this
counter when some change is detected to notify the drm part,
which can trigger for example hotplug event.

Also now call drm_connector_update_edid_property
right after we get edid always to make sure there is a
unified way to handle edid change, without having to
change tons of source code as currently
drm_connector_update_edid_property is called only in
certain cases like reprobing and not right after edid is
actually updated.

v2: Added documentation for the new counter. Rename change_counter to
    epoch_counter.

7e06886bbf drm/mipi-dbi: Remove ->enabled
The atomic helpers try really hard to not lose track of things,
duplicating enabled tracking in the driver is at best confusing.
Double-enabling or disabling is a bug in atomic helpers.

In the fb_dirty function we can just assume that the fb always exists,
simple display pipe helpers guarantee that the crtc is only enabled
together with the output, so we always have a primary plane around.

Now in the update function we need to be a notch more careful, since
that can also get called when the crtc is off. And we don't want to
upload frames when that's the case, so filter that out too.

12c683e12c drm: bridge: Pass drm_display_info to drm_bridge_funcs .mode_valid()
When validating a mode, bridges may need to do so in the context of a
display, as specified by drm_display_info. An example is the meson
dw-hdmi bridge that needs to consider the YUV 4:2:0 output format to
perform clock calculations.

Bridges that need the display info currently retrieve it from the
drm_connector created by the bridge. This gets in the way of moving
connector creation out of bridge drivers. To make this possible, pass
the drm_display_info to drm_bridge_funcs .mode_valid().

Changes to the bridge drivers have been performed with the following
coccinelle semantic patch and have been compile-tested.

471bdd0df0 drm/i915/dp_mst: Work around out-of-spec adapters filtering short pulses
Some TypeC -> native DP adapters, at least the Club 3D CAC-1557 adapter,
incorrectly filter out HPD short pulses with a duration less than
~540 usec, leading to MST probe failures.

According to the DP Standard 2.0 section 5.1.4:
- DP sinks should generate short pulses in the 500 usec -> 1 msec range
- DP sources should detect short pulses in the 250 usec -> 2 msec range

According to the DP Alt Mode on TypeC Standard section 3.9.2, adapters
should detect and forward short pulses according to how sources should
detect them as specified in the DP Standard (250 usec -> 2 msec).

Based on the above filtering out short pulses with a duration less than
540 usec is incorrect.

To make such adapters work add support for a driver polling on MST
inerrupt flags, and wire this up in the i915 driver. The sink can clear
an interrupt it raised after 110 msec if the source doesn't respond, so
use a 50 msec poll period to avoid missing an interrupt. Polling of the
MST interrupt flags is explicitly allowed by the DP Standard.

This fixes MST probe failures I saw using this adapter and a DELL U2515H
monitor.

v2:
- Fix the wait event timeout for the no-poll case.
v3 (Ville):
- Fix the short pulse duration limits in the commit log prescribed by the
  DP Standard.
- Add code comment explaining why/how polling is used.
- Factor out a helper to schedule the port's hpd irq handler and move it
  to the rest of hotplug handlers.
- Document the new MST callback.

654bf12bad drm/cma-helper: Add DRM_GEM_CMA_DRIVER_OPS to set default GEM CMA functions
The macro to DRM_GEM_CMA_DRIVER_OPS sets GEM callbacks in struct drm_driver
to their defaults for CMA. A variant of the macro is provided for drivers
that override the default .dumb_create callback. Adapt drivers to the changes.

v4:
	* remove parenthesis around dumb_create_func
	* fix grammar in commit message

42acb06b01 drm: pahole struct drm_display_mode
Reorganize drm_display_mode to eliminate all the holes.
We'll put all the actual timings to the start of the
struct and all the extra junk to the end.

Gets the size down to 136 bytes on 64bit and 120 bytes on
32bit. With a bit more work we should be able to get this
below the two cacheline mark even on 64bit.

0e799e840a drm: Restore the NULL check for drm_gem_object_put()
Some users want to pass NULL to drm_gem_object_put(), but those using
__drm_gem_object_put() did not. Compromise, have both and let the
compiler sort it out.

drm_gem_fb_destroy() calls drm_gem_object_put() with NULL obj causing:

UAPI Changes:

- drm/i915: Show per-engine default property values in sysfs

    By providing the default values configured into the kernel via sysfs, it
    is much more convenient for userspace to restore those sane defaults, or

  sed -i  "s/$__from/$__to/g" $__file;

ebdc02dd4c drm: Add DRM_MODE_TYPE_USERDEF flag to probed modes matching a video= argument
drm_helper_probe_add_cmdline_mode() prefers using a probed mode matching
a video= argument over calculating our own timings for the user specified
mode using CVT or GTF.

But userspace code which is auto-configuring the mode may want to know that
the user has specified that mode on the kernel commandline so that it can
pick that mode over the mode which is marked as DRM_MODE_TYPE_PREFERRED.

This commit sets the DRM_MODE_TYPE_USERDEF flag on the matching mode, just
as we would do on the user-specified mode when no matching probed mode is
found.

995b819f29 drm: fix trivial field description cut-and-paste error
As reported by Amarnath Baliyase, the drm_mode_status enumeration
documentation describes MODE_V_ILLEGAL as "mode has illegal horizontal
timings".  But that's just a cut-and-paste error from the previous line.
The "V" stands for vertical, of course.

I'm just fixing this directly rather than bothering with going through
the proper channels.  Less work for everybody.

0cdea4455a drm/mm: optimize rb_hole_addr rbtree search
Userspace can severely fragment rb_hole_addr rbtree by manipulating
alignment while allocating buffers. Fragmented rb_hole_addr rbtree
would result in large delays while allocating buffer object for a
userspace application. It takes long time to find suitable hole
because if we fail to find a suitable hole in the first attempt
then we look for neighbouring nodes using rb_prev()/rb_next().
Traversing rbtree using rb_prev()/rb_next() can take really long
time if the tree is fragmented.

This patch improves searches in fragmented rb_hole_addr rbtree by
modifying it to an augmented rbtree which will store an extra field
in drm_mm_node, subtree_max_hole. Each drm_mm_node now stores maximum
hole size for its subtree in drm_mm_node->subtree_max_hole. Using
drm_mm_node->subtree_max_hole, it is possible to eliminate a complete
subtree if that subtree is unable to serve a request hence reducing
number of rb_prev()/rb_next() used.

With this patch applied, 1 million bo allocs on amdgpu took ~8 sec,
compared to 50k bo allocs which took 28 sec without it.

partial test code:
int test_fragmentation(void)
{

	int i = 0;
        uint32_t  minor_version;
        uint32_t  major_version;

        struct amdgpu_bo_alloc_request request = {};
        amdgpu_bo_handle vram_handle[MAX_ALLOC] = {};
        amdgpu_device_handle device_handle;

        request.alloc_size = 4096;
        request.phys_alignment = 8192;
        request.preferred_heap = AMDGPU_GEM_DOMAIN_VRAM;

        int fd = open("/dev/dri/card0", O_RDWR | O_CLOEXEC);
        amdgpu_device_initialize(fd, &major_version,  &minor_version,
				 &device_handle);

        for (i = 0; i < MAX_ALLOC; i++) {
                amdgpu_bo_alloc(device_handle, &request, &vram_handle[i]);
        }

        for (i = 0; i < MAX_ALLOC; i++)
                amdgpu_bo_free(vram_handle[i]);

        return 0;
}

v2:
Use RB_DECLARE_CALLBACKS_MAX to maintain subtree_max_hole
v3:
insert_hole_addr() should be static a function
fix return value of next_hole_high_addr()/next_hole_low_addr()
