The DPMS handling wrt clock enables/disables was incorrect: we could end
up decrementing the clock count multiple times if we transition via
several low-power DPMS states, resulting in a kernel warning. Fix this
by only testing to see whether we are entering or exiting the DPMS off
state.

Pre DCE4 hw doesn't have reliable pageflip completion
interrupts, so instead polling for flip completion is
used from within the vblank irq handler to complete
page flips.
This causes a race if pageflip ioctl is called close to
vblank:
1. pageflip ioctl queues execution of radeon_flip_work_func.
2. vblank irq fires, radeon_crtc_handle_vblank checks for
flip_status == FLIP_SUBMITTED finds none, no-ops.
3. radeon_flip_work_func runs inside vblank, decides to
set flip_status == FLIP_SUBMITTED and programs the
flip into hw.
4. hw executes flip immediately (because in vblank), but
as 2 already happened, the flip completion routine only
emits the flip completion event one refresh later ->
wrong vblank count/timestamp for completion and no
performance gain, as instead of delaying the flip until
next vblank, we now delay the next flip by 1 refresh
while waiting for the delayed flip completion event.
Given we often don't gain anything due to this race, but
lose precision, prevent the programmed flip from executing
in vblank on pre DCE4 asics to avoid this race.
On pre-AVIVO hw we can't program the hw for edge-triggered
flips, they always execute anywhere in vblank. Therefore delay
the actual flip programming until after vblank on pre-AVIVO.

Pre DCE4 hardware doesn't have (reliable) pageflip completion
irqs, therefore we have to use the old polling method for flip
completion handling in vblank irq.
As vblank irqs fire a bit before start of vblank (when the
linebuffer fifo read position reaches end of scanout), we
have some fudge for flip completion handling in the last
lines of active scanout. Old code assumed the threshold to
be 99% of active scanout height, a ballpark estimate which
worked ok. Since we know since a while how to calculate the
actual threshold from linebuffer size, lets make use of it
to get a more accurate threshold.
This completion path is still prone to some races in corner
cases, especially on pre-AVIVO hardware, so document them
a bit better in the code comments.

There's no point in enabling PSR when the panel doesn't support it.
This also avoids a problem when PSR gets enabled when a CRTC is being
disabled, because sometimes in that situation the DSP_HOLD_VALID_INTR
interrupt on which we wait will never arrive. This was observed on
RK3288 with a panel without PSR (veyron-jaq Chromebook).
It's very easy to reproduce by running the kms_rmfb test in IGT a few

Currently we use a linear walk to lookup a handle and return a dma-buf,
and vice versa. A long overdue TODO task is to convert that to a
hashtable. Since the initial implementation of dma-buf/prime, we now
have resizeable hashtables we can use (and now a future task is to RCU
enable the lookup!). However, this patch opts to use an rbtree instead
to provide O(lgN) lookups (and insertion, deletion). rbtrees were chosen
over using the RCU backed resizable hashtable to firstly avoid the
reallocations (rbtrees can be embedded entirely within the parent
struct) and to favour simpler code with predictable worst case
behaviour. In simple testing, the difference between using the constant
lookup and insertion of the rhashtable and the rbtree was less than 10%
of the wall time (igt/benchmarks/prime_lookup) - both are dramatic
improvements over the existing linear lists.

Before commit a325725633 ("drm: Lobotomize set_busid nonsense for !pci
drivers"), several DRM drivers for platform devices used to expose an
explicit "drm_driver.set_busid" callback, invariably backed by
drm_platform_set_busid().
Commit a325725633 removed drm_platform_set_busid(), along with the
referring .set_busid field initializations. This was justified because
interchangeable functionality had been implemented in drm_dev_alloc() /
drm_dev_init(), which DRM_IOCTL_SET_VERSION would rely on going forward.
However, commit a325725633 also removed drm_virtio_set_busid(), for
which the same consolidation was not appropriate: this .set_busid callback
had been implemented with drm_pci_set_busid(), and not
drm_platform_set_busid(). The error regressed Xorg/xserver on QEMU's
"virtio-vga" card; the drmGetBusid() function from libdrm would no longer
return stable PCI identifiers like "pci:0000:00:02.0", but rather unstable
platform ones like "virtio0".

This is amdkfd's pull request for kernel 4.9. It contains a fix to a possible
infinite loop bug and a couple of other minor "cleaning" patches.
* tag 'drm-amdkfd-next-2016-09-19' of git://people.freedesktop.org/~gabbayo/linux:
drm/amdkfd: Pass 'struct queue_propertices' by reference
drm/amdkfd: Unify multiple calls to pr_debug() into one
drm/amdkfd: Fix possible infinite loop
drm/amdkfd: Reuse function to find a process through pasid
drm/amdkfd: Add some missing memset zero'ing in queue init func
drm/amdkfd: Tidy up kfd_generate_gpu_id() uint64_t bitshift unpack
* the only remaining callers of "short" fault-ins are just as happy with generic
variants (both in lib/iov_iter.c); switch them to multipage variants, kill the
"short" ones
* rename the multipage variants to now available plain ones.
* get rid of compat macro defining iov_iter_fault_in_multipage_readable by
expanding it in its only user.

Right now it's possible to trigger fence_drv.fences[] dereference after
the array has been freed. While the real problem is elsewhere, this still
results in confusing errors that depend on how the freed memory was
reused (I've seen "kernel tried to execute NX-protected page"), it's
better to clear them and get NULL dereference so that it's obvious what's
going wrong.

In order to reduce the time required to turn on the panel, this patch
makes 2 assumptions:
1- In detect(): if there's a panel, we're connected.
2- In get_modes(): if there's a panel, let the panel driver decide if
it should prepare/unprepare in order to get the modes.
The first is straightforward, and shouldn't need further explanation. The
second should eliminate the prepare/unprepare delays from get_modes() in
most cases, since panels generally hardcode their modes in the driver as
opposed to reading EDID. If a panel does need to read EDID, it should be
responsible for ensuring it's in a state in which it can.
Signed-off-by: Sean Paul <seanpaul@chromium.org>
If there's a panel connected to the analogix_dp bridge, rely on
the panel driver for modes, rather than reading EDID *and* calling
get_modes() on the panel.
This allows panels with a valid EDID to read it in the panel driver
(e.g. simple_panel), and panels with invalid EDID to homebrew modes
in their get_modes implementation.

The connector shouldn't be registered until the rest of the whole device
is set up, so that consistent state is presented to userspace.
As drm_dev_register() now registers all of the connectors anyway,
there's no need to explicitly do it in individual drivers so remove
the calls to drm_connector_register()/drm_connector_unregister().
This allows componentised drivers to use tda998x without having racy

This patch makes the driver send the pending vblank event in next vblank

Originally we needed to enable vblank for any atomic commit to kick the
PSR machine, but that was changed and we no longer need to do so from
a vblank interrupt. Let's return to original behavior of enabling
vblank only if it is really necessary.

vblank without event").
Signed-off-by: Tomasz Figa <tfiga@chromium.org>
Currently the driver uses a custom function to wait for flip to complete
after an atomic commit. It was needed before because of two problems:
- there is no hardware vblank counter, so the original helper would
have a race condition with the vblank interrupt,
- the driver didn't support unreferencing cursor framebuffers
asynchronously to the commit, which was what the helper expected.
Since both problems have been solved by previous patches, we can now
make the driver use the generic helper and remove custom waiting code.
Signed-off-by: Tomasz Figa <tfiga@chromium.org>
Currently the driver waits for vblank and then unreferences old
framebuffers from atomic commit code path. This is however breaking the
legacy cursor API, which requires the updates to be fully asynchronous.
Instead of just adding a special case for cursor, we can have actually
smaller amount of code to unreference any changed framebuffer from a
flip work.
Signed-off-by: Tomasz Figa <tfiga@chromium.org>
Since VOP does not have a hardware vblank count register, the ongoing
commit might be racing with a requested vblank interrupt, which would
increment the software vblank counter before the changes being committed
actually happen.
To avoid this, we can extend .atomic_flush(), so after it sets cfg_done
bit, it polls the vblank interrupt bit until it's inactive to make sure
that any old vblank interrupt gets to the handler and then uses
synchronize_irq(vop->irq) to make sure the handler finishes running.
The polling case should happen very rarely, but even if, the total wait
time should be relatively low and in practice almost equal to the vop
hardirq handler running time.

The enable register only masks the raw status bits to signal CPU
interrupt only for enabled interrupts. The status bits are activated
regardless of the enable register. This means that we might have an old

Instead of keying off vblank for psr, just flush every time
we get an atomic update. This ensures that cursor updates
will properly disable psr (without turning vblank on/off),
and unifies the paths between fb_dirty and atomic psr
enable/disable.

The qxl driver currently destroys and recreates the
qxl "primary" any time the first crtc is set.
A side-effect of destroying the primary is mouse state
associated with the crtc is lost, which leads to
disappearing mouse cursors on wayland sessions.
This commit changes the driver to reapply the cursor
any time SetCrtc is called. It achieves this by keeping
a reference to the cursor bo on the qxl_crtc struct.

The qemu stdvga can be configured with a wide range of video memory,
from 1 MB to 256 MB (default is 16 MB). In case it is configured
with only 1 or 2 MB it isn't really usable with bochsdrm, due to
depths other than 32bpp not being supported so that isn't enough
memory for a reasonable sized framebuffer. So skip the device

Various cleanups to the DRM core initialization and exit handlers:
- Register chrdev last: Once register_chrdev() returns, open() will
succeed on the given chrdevs. This is usually not an issue, as no
chardevs are registered, yet. However, nodes can be created by
user-space via mknod(2), even though such major/minor combinations are
unknown to the kernel. Avoid calling into drm_stub_open() in those
cases.
Again, drm_stub_open() would just bail out as the inode is unknown,
but it's really non-obvious if you hack on drm_stub_open().
- Unify error-paths into just one label. All the error-path helpers can
be called even though the constructors were not called yet, or failed.
Hence, just call all cleanups unconditionally.
- Call into drm_global_release(). This is a no-op, but provides
debugging helpers in case there're GLOBALS left on module unload. This
function was unused until now.
- Use DRM_ERROR() instead of printk(), and also print the error-code on
failure (even if it is static!).
- Don't throw away error-codes of register_chrdev()!
- Don't hardcode -1 as errno. This is just plain wrong.
- Order exit-handlers in the exact reverse order of initialization
(except if the order actually matters for syncing-reasons, which is
not the case here, though).
v2:
- Call drm_core_exit() directly from the init-error-handler. Requires to
drop __exit annotation, though.

The drm_core.h header contains a set of constants meant to be used
throughout DRM. However, as it turns out, they're each used just once and
don't bring any benefit. They're also grossly mis-named and lack
name-spacing. This patch inlines them, or moves them into drm_internal.h
as appropriate:
- CORE_AUTHOR and CORE_DESC are inlined into corresponding MODULE_*()
macros. It's just confusing having to follow 2 pointers when trying to
find the definition of these fields. Grep'ping for MODULE_AUTHOR()
should reveal the full information, if there's no strong reason not to.
- CORE_NAME, CORE_DATE, CORE_MAJOR, CORE_MINOR, and CORE_PATCHLEVEL are
inlined into the sysfs 'version' attribute. They're stripped
everywhere else (which is just some printk() statements). CORE_NAME
just doesn't make *any* sense, as we hard-code it in many places,
anyway. The other constants are outdated and just serve
binary-compatibility purposes. Hence, inline them in 'version' sysfs
attribute (we might even try dropping it..).
- DRM_IF_MAJOR and DRM_IF_MINOR are moved into drm_internal.h as they're
only used by the global ioctl handlers. Furthermore, versioning
interfaces breaks backports and as such is deprecated, anyway. We just
keep them for historic reasons. I doubt anyone will ever modify them
again.

Each DRM file-context caches the EUID of the process that opened the file.
It is used exclusively for debugging purposes in /proc/dri/ and friends.
Note, however, that we can already fetch the EUID from
priv->pid->task->creds. The pointer-chasing will not hurt us, since it is
only about debugging, anyway.
Since we already are in an rcu-read-side, we can use __task_cred() rather
than task_cred_xxx().

Similar to struct drm_update_draw, struct drm_mode_fb_cmd2 has an
unaligned 64 bit field (modifier). This get packed differently between
32 bit and 64 bit modes on architectures that can handle unaligned 64
bit access (X86 and IA64). Other architectures pack the structs the
same and don't need the compat wrapper. Use the same condition for
drm_mode_fb_cmd2 as we use for drm_update_draw.
Note that only the modifier will be packed differently between compat
and non-compat versions.

drm/bridge: adv7511: add support for the 2nd chip
This patch implements image conversion support using the IC tasks, with
tiling to support scaling to and from images up to 4096x4096. Image
rotation is also supported. Image conversion requests are added to
a run queue under the IC tasks.
The internal API is subsystem agnostic (no V4L2 dependency except
for the use of V4L2 fourcc pixel formats).
Callers prepare for image conversion by calling
ipu_image_convert_prepare(), which initializes the parameters of
the conversion. The caller passes in the ipu and IC task to use for
the conversion, the input and output image formats, a rotation mode,
and a completion callback and completion context pointer:
struct ipu_image_converter_ctx *
ipu_image_convert_prepare(struct ipu_soc *ipu, enum ipu_ic_task ic_task,
struct ipu_image *in, struct ipu_image *out,
enum ipu_rotate_mode rot_mode,
ipu_image_converter_cb_t complete,
void *complete_context);
A new conversion context is created that is added to an IC task
context queue. The caller is given the new conversion context,
which can then be passed to the further APIs:
int ipu_image_convert_queue(struct ipu_image_converter_run *run);
This queues the given image conversion request run to a run queue,
and starts the conversion immediately if the run queue is empty. Only
the physaddr's of the input and output image buffers are needed,
since the conversion context was created previously with
ipu_image_convert_prepare(). When the conversion completes, the run
pointer is returned to the completion callback.
void ipu_image_convert_abort(struct ipu_image_converter_ctx *ctx);
This will abort any active or pending conversions for this context.
Any currently active or pending runs belonging to this context are
returned via the completion callback with an error status.
void ipu_image_convert_unprepare(struct ipu_image_converter_ctx *ctx);
Unprepares the conversion context. Any active or pending runs will
be aborted by calling ipu_image_convert_abort().

of_match_device could return NULL, and so cause a NULL pointer
dereference later.
For fixing this problem, we use of_device_get_match_data(), this will
simplify the code a little by using a standard function for
getting the match data.
Testing the return value of of_device_get_match_data is also necessary
for avoiding a second NULL deref later on devtype.

When CONFIG_PM is not set, we get a warning about an unused function:

This removes the two #ifdef checks in this file and instead marks the
functions as __maybe_unused, which is a more reliable way of doing the
same, allowing better build coverage and avoiding the warning above.

When reading back the divider set in the register, we mask off the

here was not converted from the field width.
Fix this by converting the field width to a proper bit mask.
