f8577fb3c2 drm/i915: Write GPU relocs harder with gen3
Under moderate amounts of GPU stress, we can observe on Bearlake and
Pineview (later gen3 models) that we execute the following batch buffer
before the write into the batch is coherent. Adding extra (tested with
upto 32x) MI_FLUSH to either the invalidation, flush or both phases does
not solve the incoherency issue with the relocations, but emitting the
MI_STORE_DWORD_IMM twice does. So be it.

78abd9e2c8 drm/i915: Downgrade unknown CSR firmware warnings
Like it was done in commit 9e180d9991 ("drm/i915: Downgrade unknown
firmware warnings") for huc and guc: downgrade CSR firmware warnings. If
we have released no firmware yet for a platform, stop scaring the
consumer and merely note its expected absence.

By simply removing the warning and early return we hit the condition
with the appropriate message.

v8: Edited commit message to be more clear about skl+, renamed
    PLANE_CTL_FORMAT_AYUV to PLANE_CTL_FORMAT_XYUV as this format
    doesn't support per-pixel alpha. Fixed minor code issues.

v9: Moved DRM format check to proper place in intel_framebuffer_init.

v10: Changed DRM_FORMAT_XYUV to be DRM_FORMAT_XYUV8888

v11: Fixed rebase conflict, caused by added new formats to drm-tip

b39b5394fa drm/gem: Add drm_gem_object_funcs
This adds an optional function table on GEM objects.
The main benefit is for drivers that support more than one type of
memory (shmem,vram,cma) for their buffers depending on the hardware it
runs on. With the callbacks attached to the GEM object itself, it is
easier to have core helpers for the the various buffer types. The driver
only has to make the decision about buffer type on GEM object creation
and all other callbacks can be handled by the chosen helper.

drm_driver->gem_prime_res_obj has not been added since there's a todo to
put a reservation_object into drm_gem_object.

v3: Add todo entry

v2: Drop drm_gem_object_funcs->prime_mmap in favour of
drm_gem_prime_mmap() (Daniel Vetter)

v1:
- drm_gem_object_funcs.map -> .prime_map let it only do PRIME mmap like
  the function it superseeds (Daniel Vetter)
- Flip around the if ladders and make obj->funcs the first choice

Under moderate amounts of GPU stress, we can observe on Bearlake and
Pineview (later gen3 models) that we execute the following batch buffer
before the write into the batch is coherent. Adding extra (tested with
upto 32x) MI_FLUSH to either the invalidation, flush or both phases does
not solve the incoherency issue with the relocations, but emitting the
MI_STORE_DWORD_IMM twice does. So be it.

Quite obviously the driver depends on I2C_MUX, but adding a "depends on"
introduces a recursive dependency, therefore this patch selects I2C_MUX

8830f26bcd drm/i915: Prevent machine hang from Broxton's vtd w/a and error capture
Since capturing the error state requires fiddling around with the GGTT
to read arbitrary buffers and is itself run under stop_machine(), it
deadlocks the machine (effectively a hard hang) when run in conjunction
with Broxton's VTd workaround to serialize GGTT access.

v2: Store the ERR_PTR in first_error so that the error can be reported
to the user via sysfs.
v3: Mention the quirk in dmesg (using info as per usual)

a4233cc944 drm/amd/pp: handle negative values when reading OD
Reading the sysfs files pp_sclk_od and pp_mclk_od return the
percentage difference between the VBIOS-provided default
frequency and the current (possibly user-set) frequency in
the highest SCLK and MCLK DPM states, respectively.

Writing to these files provides an easy mechanism for
setting a higher-than-default maximum frequency. We
normally only allow values >= 0 to be written here.

However, with the addition of pp_od_clk_voltage, we now
allow users to set custom DPM tables. If they then set
the maximum DPM state to something less than the default,
later reads of pp_*_od should return a negative value.
The highest DPM state is now less than the VBIOS-provided
default, so the percentage is negative.

The math to calculate this was originally performed with
unsigned values, meaning reads that should return negative
values returned meaningless data. This patch corrects that
issue and normalizes how all of the calculations are done
across the various hwmgr types.

fa68d4f847 drm/rockchip: fix for mailbox read size
Some of the functions (like cdn_dp_dpcd_read, cdn_dp_get_edid_block)
allow to read 64KiB, but the cdn_dp_mailbox_read_receive, that is
used by them, can read only up to 255 bytes at once. Normally, it's
not a big issue as DPCD or EDID reads won't (hopefully) exceed that
value.
The real issue here is the revocation list read during the HDCP
authentication process. (problematic use case:
https://chromium.googlesource.com/chromiumos/third_party/kernel/+/chromeos-4.4/drivers/gpu/drm/rockchip/cdn-dp-reg.c#1152)
The list can reach 127*5+4 bytes (num devs * 5 bytes per ID/Bksv +
4 bytes of an additional info).
In other words - CTSes with HDCP Repeater won't pass without this
fix. Oh, and the driver will most likely stop working (best case
scenario).

21556350ad drm/i915: Disable LP3 watermarks on all SNB machines
I have a Thinkpad X220 Tablet in my hands that is losing vblank
interrupts whenever LP3 watermarks are used.

If I nudge the latency value written to the WM3 register just
by one in either direction the problem disappears. That to me
suggests that the punit will not enter the corrsponding
powersave mode (MPLL shutdown IIRC) unless the latency value
in the register matches exactly what we read from SSKPD. Ie.
it's not really a latency value but rather just a cookie
by which the punit can identify the desired power saving state.
On HSW/BDW this was changed such that we actually just write
the WM level number into those bits, which makes much more
sense given the observed behaviour.

We could try to handle this by disallowing LP3 watermarks
only when vblank interrupts are enabled but we'd first have
to prove that only vblank interrupts are affected, which
seems unlikely. Also we can't grab the wm mutex from the
vblank enable/disable hooks because those are called with
various spinlocks held. Thus we'd have to redesigne the
watermark locking. So to play it safe and keep the code
simple we simply disable LP3 watermarks on all SNB machines.

To do that we simply zero out the latency values for
watermark level 3, and we adjust the watermark computation
to check for that. The behaviour now matches that of the
g4x/vlv/skl wm code in the presence of a zeroed latency
value.

v2: s/USHRT_MAX/U32_MAX/ for consistency with the types (Chris)

5478ad10e7 drm/ast: Remove existing framebuffers before loading driver
If vesafb attaches to the AST device, it configures the framebuffer memory
for uncached access by default. When ast.ko later tries to attach itself to
the device, it wants to use write-combining on the framebuffer memory, but
vesefb's existing configuration for uncached access takes precedence. This
results in reduced performance.

Removing the framebuffer's configuration before loding the AST driver fixes
the problem. Other DRM drivers already contain equivalent code.

07e3a1cfb0 drm/amd/display: Support amdgpu "max bpc" connector property (v2)
[Why]
Many panels support more than 8bpc but some modes are unavailable while
running at greater than 8bpc due to DP/HDMI bandwidth constraints.

Support for more than 8bpc was added recently in the driver but it
defaults to the maximum supported bpc - locking out these modes.

This should be a user configurable option such that the user can select
what bpc configuration they would like.

[How]
This patch adds support for getting and setting the amdgpu driver
specific "max bpc" property on the connector.

It also adds support for limiting the output bpc based on the property
value. The default limitation is the lowest value in the range, 8bpc.
This was the old value before the range was uncapped.

This patch should be updated/replaced later once common drm support
for max bpc lands.

[How]
This patch introduces the "max bpc" amdgpu driver specific connector
property so the user can limit the maximum bpc. It ranges from 8 to 16.

This doesn't directly set the preferred bpc for the panel since it
follows Intel's existing driver conventions.

This proprety should be removed once common drm support for max bpc
lands.

5a43911fd2 drm/vc4: Fix NULL pointer dereference in the async update path
vc4_plane_atomic_async_update() calls vc4_plane_atomic_check()
which in turn calls vc4_plane_setup_clipping_and_scaling(), and since
commit 58a6a36fe8 ("drm/vc4: Use
drm_atomic_helper_check_plane_state() to simplify the logic"), this
function accesses plane_state->state which will be NULL when called
from the async update path because we're passing the current plane
state, and plane_state->state has been assigned to NULL in
drm_atomic_helper_swap_state().

Pass the new state instead of the current one (the new state has
->state set to a non-NULL value).

21d808405f drm/bridge/sii902x: Fix EDID readback
While adding SiI9022A support to the iwg23s board, it came
up that when the HDMI transmitter is in pass through mode the
device is not compliant with the I2C specification anymore,
as it requires a far bigger tbuf, due to a delay the HDMI
transmitter is adding when relaying the STOP condition on the
monitor i2c side of things.

When not providing an appropriate delay after the STOP condition
the i2c bus would get stuck. Also, any other traffic on the bus
while talking to the monitor may cause the transaction to fail
or even cause issues with the i2c bus as well.

I2c-gates seemed to reach consent as a possible way to address
these issues, and as such this patch is implementing a solution
based on that. Since others are clearly relying on the current
implementation of the driver, this patch won't require any DT
changes.

Since we don't want any interference during the DDC Bus
Request/Grant procedure and while talking to the monitor, we
have to use the adapter locking primitives rather than the
i2c-mux locking primitives.

a56f9c868c drm/virtio: add uapi for in and out explicit fences
Add a new field called fence_fd that will be used by userspace to send
in-fences to the kernel and receive out-fences created by the kernel.

This uapi enables virtio to take advantage of explicit synchronization of
dma-bufs.

There are two new flags:

* VIRTGPU_EXECBUF_FENCE_FD_IN to be used when passing an in-fence fd.
* VIRTGPU_EXECBUF_FENCE_FD_OUT to be used when requesting an out-fence fd

The execbuffer IOCTL is now read-write to allow the userspace to read the
out-fence.

On error -1 should be returned in the fence_fd field.

fa96ed1f56 drm/i915: Remove special case for power well 1/MISC_IO state verification
Even though PW#1 and the MISC_IO power wells are managed by the
DMC firmware (toggled dynamically if conditions allow it) from the
driver's POV they are always on if the display core is initialized
(always restored by DMC to the enabled state after exiting from DC5/6
for instance b/c of MMIO access). Accordingly we can just mark them as
always-on and remove the special casing for them during state
verification (thus enabling verification for these power wells too).

cb8ef723ab drm/i915/gen9_bc: Work around DMC bug zeroing power well requests
A DMC bug on GEN9 big core machines fails to restore the driver's
request bits for the PW1 and MISC_IO power wells after a DC5/6
entry->exit sequence. As a consequence the driver's subsequent check for
the enabled status of these power wells will fail, as the check
considers the power wells being enabled only if both the status and
request bits are set. To work around this borrow the request bits from
BIOS's own request register in which DMC forces on the request bits when
exiting from DC5/6.

This fixes a problem reported by Ramalingam, where HDCP init failed,
since PW1 reported itself as being disabled, while in reality it was
enabled.

704e504bd6 drm/i915: add ICP support to cnp_rawclk() and kill icp_rawclk()
I think I'm probably the one who argued in favor of having separate
implementations for both PCHs, but the calculations are actually the
same, the clocks are the same and the only difference is that on ICP
we write the numerator to the register.

I have previously suggested to kill cnp_rawclk() and keep the
icp_rawclk() style, but Ville gave some good arguments that what's in
this patch may be the better choice.

v2: Switch numerator to 1 from 1000 and adjust calculations

that). The ICP spec renamed the field to "Counter Fraction
Denominator", which makes a lot more sense. Use the more complete ICL
naming because we will merge the CNP and ICP functions into a single
one, which will introduce the concept of the numerator. That will make

c1cd5b24d6 drm/i915: Determine DSI panel orientation from VBT
VBT appears to have two (or possibly three) ways to indicate the panel
rotation. The first is in the MIPI config block, but that apparenly
usually (maybe always?) indicates 0 degrees despite the actual panel
orientation. The second way to indicate this is in the general features
block, which can just indicate whether 180 degress rotation is used.
The third might be a separate rotation data block, but that is not
at all documented so who knows what it may contain.

Let's try the first two. We first try the DSI specicic VBT
information, and it it doesn't look trustworthy (ie. indicates
0 degrees) we fall back to the 180 degree thing. Just to avoid too
many changes in one go we shall also keep the hardware readout path
for now.

If this works for more than just my VLV FFRD the question becomes
how many of the panel orientation quirks are now redundant?

There is no harm in writing both registers. Which one gets

7db647aa8b drm/meson: Add primary plane scaling
This patch adds support for the Primary Plane scaling.

On the Amlogic GX SoCs, the primary plane is used as On-Screen-Display
layer on top of video, and it's needed to keep the OSD layer to a lower
size as the physical display size to :
- lower the memory bandwidth
- lower the OSD rendering
- lower the memory usage

This use-case is used when setting the display mode to 3840x2160 and the
OSD layer is rendered using the GPU. In this case, the GXBB & GXL cannot
work on more than 2000x2000 buffer, thus needing the OSD layer to be kept
at 1920x1080 and upscaled to 3840x2160 in hardware.

The primary plane atomic check still allow 1:1 scaling, allowing native
3840x2160 if needed by user-space applications.

f9a2348196 drm/meson: Support Overlay plane for video rendering
The Amlogic Meson GX SoCs support an Overlay plane behind the primary
plane for video rendering.

This Overlay plane support various YUV layouts :
- YUYV
- NV12 / NV21
- YUV444 / 422 / 420 / 411 / 410

The scaler supports a wide range of scaling ratios, but for simplicity,
plane atomic check limits the scaling from x5 to /5 in vertical and
horizontal scaling.

The z-order is fixed and always behind the primary plane and cannot be changed.

The scaling parameter algorithm was taken from the Amlogic vendor kernel
code and rewritten to match the atomic universal plane requirements.

The video rendering using this overlay plane support has been tested using
the new Kodi DRM-KMS Prime rendering path along the in-review V4L2 Mem2Mem
Hardware Video Decoder up to 3840x2160 NV12 frames on various display modes.

44a7276b30 drm/i915: Fix hpd handling for pins with two encoders
In my haste to remove irq_port[] I accidentally changed the
way we deal with hpd pins that are shared by multiple encoders
(DP and HDMI for pre-DDI platforms). Previously we would only
handle such pins via ->hpd_pulse(), but now we queue up the
hotplug work for the HDMI encoder directly. Worse yet, we now
count each hpd twice and this increment the hpd storm count
twice as fast. This can lead to spurious storms being detected.

Go back to the old way of doing things, ie. delegate to
->hpd_pulse() for any pin which has an encoder with that hook
implemented. I don't really like the idea of adding irq_port[]
back so let's loop through the encoders first to check if we
have an encoder with ->hpd_pulse() for the pin, and then go
through all the pins and decided on the correct course of action
based on the earlier findings.

I have occasionally toyed with the idea of unifying the pre-DDI
HDMI and DP encoders into a single encoder as well. Besides the
hotplug processing it would have the other benefit of preventing
userspace from trying to enable both encoders at the same time.
That is simply illegal as they share the same clock/data pins.
We have some testcases that will attempt that and thus fail on
many older machines. But for now let's stick to fixing just the
hotplug code.

Ensure that the writes into the context image are completed prior to the

by the SDM that all writes are flushed before an uncached memory
transaction (our mmio write to submit the context to HW for execution),
we have empirical evidence to believe that this is not actually the
case.

This appears to be due to the fact that with an MST topology, not all
intel_connector structs will have ->encoder set. So, fix this by
skipping connectors without encoders in
intel_hpd_irq_storm_reenable_work().

For those wondering, this bug was found on accident while simulating HPD
storms using a Chamelium connected to a ThinkPad T450s (Broadwell).

Changes since v1:
- Check intel_connector->mst_port instead of intel_connector->encoder

Syrjälä pointed out - we need to make sure that
intel_connector->mst_port is set before initializing MST connectors,
since in theory we could potentially check intel_connector->mst_port in
i915_hpd_poll_init_work() after registering the connector but before
having written it's value.

fb5bbae9b1 drm/i915/ringbuffer: Delay after EMIT_INVALIDATE for gen4/gen5
Exercising the gpu reloc path strenuously revealed an issue where the
updated relocations (from MI_STORE_DWORD_IMM) were not being observed
upon execution. After some experiments with adding pipecontrols (a lot
of pipecontrols (32) as gen4/5 do not have a bit to wait on earlier pipe
controls or even the current on), it was discovered that we merely
needed to delay the EMIT_INVALIDATE by several flushes. It is important
to note that it is the EMIT_INVALIDATE as opposed to the EMIT_FLUSH that
needs the delay as opposed to what one might first expect -- that the
delay is required for the TLB invalidation to take effect (one presumes
to purge any CS buffers) as opposed to a delay after flushing to ensure
the writes have landed before triggering invalidation.

ironlake_check_fdi_lanes() may try to grab some extra crtc locks.

24ec84e854 drm/omap: Move DISPC runtime PM handling to omapdrm
The internal encoders (DSI, HDMI4, HDMI5 and VENC) runtime PM handlers
attempt to manage the runtime PM state of the connected DISPC, based on
the rationale that the DISPC providing data to the encoders requires
ensuring that the display is active whenever the encoders are active.

While the DISPC provides data to the encoders, it doesn't as such
constitute a resource that encoders require in order to be taken out
of suspend, contrary to for instance a functional clock or a power
supply. Encoders registers can be accessed without the DISPC being
active, and while the encoders will not output any video stream without
being fed by the DISPC, the DISPC PM state doesn't influence the
encoders PM state.

For this reason the DISPC PM state is better managed from the omapdrm
driver, in the CRTC enable and disable operations. This allows the
encoders PM state to be handled separately from the DISPC, and in
particular at times when the DISPC may not be available (for instance at
probe due to the DSS probe being deferred, or at remove time du to the
DISPC being already removed).

e0c827aca0 drm/omap: Populate DSS children in omapdss driver
The DSS DT node contains children that describe the DSS components
(DISPC and internal encoders). Each of those components is handled by a
platform driver, and thus needs to be backed by a platform device.

The corresponding platform devices are created in mach-omap2 code by a
call to of_platform_populate(). While this approach has worked so far,
it doesn't model the hardware architecture very well, as it creates
child devices before the parent is ready to handle them. This would be
akin to creating I2C slaves before the I2C master is available.

The task can be easily performed in the omapdss driver code instead,
simplifying mach-omap2 code. We however can't remove the mach-omap2 code
completely as the omap2fb driver still depends on it, but we can move it
to the omap2fb-specific section, where it can stay until the omap2fb
driver gets removed.

This has the added benefit of not allowing DSS components to probe
before the DSS itself, which led to runtime PM issues when the DSS probe
is deferred.

3aefb67f84 drm/i915: Sanitize PCH port transcoder select on IBX
IBX has a documented workaround which states that when we disable the
port we must change its transcoder select to A, otherwise it will
prevent the other port (DP vs. HDMI/SDVO) from using transcoder A.
We implement the workaround during encoder disable, but looks like
some BIOSen leave transcoder B selected even when the port wasn't
actually enabled by the BIOS. That will trip up our asserts
that attempt to make sure we never forget this w/a.

Sanitize the transcoder select to A for all disabled PCH
DP/HDMI/SDVO ports. We assume that the port was never enabled
by the BIOS on transcoder B, because if it had we'd actually have
to toggle the port on and back off to properly switch it back to
transcoder A. That would cause some display flicker if transcoder A
is already enabled on some other port, so it's better not to do it
unless absolutely necessary. Since we have no indication that the
transcoder select is misbehaving on the affected machines we can
assume the port was never actually enabled by the BIOS.

This cures warning like this during driver load:
IBX PCH DP C still using transcoder B
WARNING: CPU: 2 PID: 172 at drivers/gpu/drm/i915/intel_display.c:1279 assert_pch_dp_disabled+0x9e/0xb0 [i915]

v2: Add comments to remind the reader that SDVOB==HDMIB (Chris)

5a3aeca97a drm/i915: Fix hpd handling for pins with two encoders
In my haste to remove irq_port[] I accidentally changed the
way we deal with hpd pins that are shared by multiple encoders
(DP and HDMI for pre-DDI platforms). Previously we would only
handle such pins via ->hpd_pulse(), but now we queue up the
hotplug work for the HDMI encoder directly. Worse yet, we now
count each hpd twice and this increment the hpd storm count
twice as fast. This can lead to spurious storms being detected.

Go back to the old way of doing things, ie. delegate to
->hpd_pulse() for any pin which has an encoder with that hook
implemented. I don't really like the idea of adding irq_port[]
back so let's loop through the encoders first to check if we
have an encoder with ->hpd_pulse() for the pin, and then go
through all the pins and decided on the correct course of action
based on the earlier findings.

I have occasionally toyed with the idea of unifying the pre-DDI
HDMI and DP encoders into a single encoder as well. Besides the
hotplug processing it would have the other benefit of preventing
userspace from trying to enable both encoders at the same time.
That is simply illegal as they share the same clock/data pins.
We have some testcases that will attempt that and thus fail on
many older machines. But for now let's stick to fixing just the
hotplug code.

0560054da5 drm/vc4: ->x_scaling[1] should never be set to VC4_SCALING_NONE
For the YUV conversion to work properly, ->x_scaling[1] should never
be set to VC4_SCALING_NONE, but vc4_get_scaling_mode() might return
VC4_SCALING_NONE if the horizontal scaling ratio exactly matches the
horizontal subsampling factor. Add a test to turn VC4_SCALING_NONE
into VC4_SCALING_PPF when that happens.

The old ->x_scaling[0] adjustment is dropped as I couldn't find any
mention to this constraint in the spec and it's proven to be
unnecessary (I tested various multi-planar YUV formats with scaling
disabled, and all of them worked fine without this adjustment).

30f5ccfa8c drm/i915/icl: Fix PLL mapping sanitization for DP ports
We shouldn't consider an encoder inactive if it doesn't have a CRTC
linked, but has virtual MST encoders with a crtc linked. Fix this.

Also we should not sanitize the mapping for MST encoders, as it's always
their primary encoder (which could be even in SST mode) whose active
state determines if we need the clock being enabled for the
corresponding physical port. Fix this too.

This fixes at least an existing breakage where we incorrectly disabled
the clock for an active DP encoder when sanitizing its MST virtual
encoders. Not sure if there are BIOSes that enable an output in MST
mode, but our HW readout is mostly missing for it anyway, so just warn
for that case.

Instead of retrieving the connector from the panel, get it from the

Even in the case of bridges, the connector is registered with the
