nr is indirectly controlled by user-space, hence leading to a
potential exploitation of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
drivers/gpu/drm/drm_ioctl.c:805 drm_ioctl() warn: potential spectre issue 'dev->driver->ioctls' [r]
drivers/gpu/drm/drm_ioctl.c:810 drm_ioctl() warn: potential spectre issue 'drm_ioctls' [r] (local cap)
drivers/gpu/drm/drm_ioctl.c:892 drm_ioctl_flags() warn: potential spectre issue 'drm_ioctls' [r] (local cap)
Fix this by sanitizing nr before using it to index dev->driver->ioctls
and drm_ioctls.
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

Now that the plane code takes the margins setup into account, we can
safely attach margin props to the HDMI connector.
We also take care of filling AVI infoframes correctly to expose the
top/botton/left/right bar.
Note that those margin props match pretty well the
overscan_{left,right,top,bottom} properties defined in config.txt and
parsed by the VC4 firmware.

Applyin margins is just a matter of scaling all planes appropriately
and adjusting the CRTC X/Y offset to account for the
left/right/top/bottom borders.
Create a vc4_plane_margins_adj() function doing that and call it from
vc4_plane_setup_clipping_and_scaling() so that we are ready to attach
margins properties to the HDMI connector.

[Why]
The behavior of drm_atomic_helper_cleanup_planes differs depending on
whether the commit was asynchronous or not. When it's called from
amdgpu_dm_atomic_commit_tail during a typical atomic commit the
plane state has been swapped so it calls cleanup_fb on the old plane
state.
However, in the asynchronous commit codepath the call to
drm_atomic_helper_commit also calls dm_plane_helper_cleanup_fb after
atomic_async_update has been called. Since the plane state is updated
in place and has not been swapped the cleanup_fb call affects the new
plane state.
This results in a use after free for the given sequence:
- Fast update, fb1 pin/ref, fb1 unpin/unref
- Fast update, fb2 pin/ref, fb2 unpin/unref
- Slow update, fb1 pin/ref, fb2 unpin/unref
- Fast update, fb2 pin/ref -> use after free. bug
[How]
Disallow framebuffer changes in the fast path. Since this includes
a NULL framebuffer, this means that only framebuffers that have
been previously pin+ref at least once will be used, preventing a
use after free.
This has a significant throughput reduction for cursor updates where
the framebuffer changes. For most desktop usage this isn't a problem,
but it does introduce performance regressions for two specific IGT
tests:
- cursor-vs-flip-toggle
- cursor-vs-flip-varying-size

Add a fallback detection method for TypeC legacy ports in case the
VBT port information used to detect normally such ports is
incorrect.
For the fallback method we use the TypeC legacy mode specific HPD
interrupt flag which should only be raised for a legacy port.
WARN if the VBT port info is incorrect.
In a case where we'd detect the port in a contradicting way both as a
legacy and also as a USB DP and/or TBT alternate port treat the port
as legacy (by also emitting a WARN from icl_update_tc_port_type).
v2:
- Repurpose the detection as a fallback method instead of using
it only for the DP legacy case. By now we should normally use VBT to
detect DP legacy ports as well.

Atm HPD disconnect events on TypeC ports will break things, since we'll
switch the TypeC mode (between legacy and disconnected modes as well as
among USB DP alternate, Thunderbolt alternate and disconnected modes) on
the fly from the HPD disconnect interrupt work while the port may be
still active.
Even if the port happens to be not active during the disconnect we'd
still have a problem during a subsequent modeset or AUX transfer that
could happen regardless of the port's connected state. For instance the
system resume display mode restore code and userspace could perform a
modeset on the port or userspace could start an AUX transfer even if the
port is in disconnected state.
To fix this keep TypeC legacy ports in legacy mode whenever we're not
suspended. This mode is a static configuration as opposed to the
Thunderbolt and USB DP alternate modes between which we can switch
dynamically.
We determine if a TypeC port is legacy (wired to a legacy HDMI or a
legacy DP connector) via the VBT DDI port specific USB-TypeC and
Thunderbolt flags. If both these flags are cleared then the port is
configured for legacy mode.
On such legacy ports we'll run the TypeC PHY connect sequence explicitly
during driver loading and system resume (vs. running the sequence during
HPD processing). The connect will succeed even if the display is not
connected to begin with (or disappears during the suspended state) since
for legacy ports the PORT_TX_DFLEXDPPMS / DP_PHY_MODE_STATUS_COMPLETED
flag is always set (as opposed to the USB DP alternate mode where it
gets set only when a display is connected).
Correspondingly run the TypeC PHY disconnect sequence during system
suspend and driver unloading. For the unloading case I had to split
up intel_dp_encoder_destroy() to be able to have the 1. flush any
pending encoder work, 2. disconnect TC PHY, 3. call DRM core cleanup and
kfree on the encoder object.
For now run the PHY disconnect during suspend only for TypeC legacy
ports. We will need to disconnect even in USB DP alternate mode in the
future, but atm we don't have a way to reconnect the port in this mode
during resume if the display disappears while being suspended. So for
now punt on this case.
Note that we do not disconnect the port during runtime suspend; in
legacy mode there are no shared HW resources (PHY lanes) with other HW
blocks (USB), so no need to release / reacquire these resources as with
USB DP alternate mode. The only reason to disconnect legacy ports during
system suspend is that the PORT_TX_DFLEXDPPMS /
DP_PHY_MODE_STATUS_COMPLETED flag must be rechecked and the port must be
connected again during system resume. We'll also have to turn the check
for this flag into a poll, after figuring out what's the proper timeout
value for it.
v2:
- Remove the redundant special casing of legacy mode when doing a
disconnect in icl_tc_port_connected(). It's guaranteed already that we
won't disconnect legacy ports in that function.
- Add a note about the new intel_ddi_encoder_destroy() hook.
- Reword the commit message after switching to the VBT based detection.

Having completed a test run of gem_eio across all machines in CI we also
observe the phenomenon (of lost interrupts after resetting the GPU) on
gen3 machines as well as the previously sighted gen6/gen7. Let's apply
the same HWSTAM workaround that was effective for gen6+ for all, as
although we haven't seen the same failure on gen4/5 it seems prudent to
keep the code the same.
As a consequence we can remove the extra setting of HWSTAM and apply the
register from a single site.
v2: Delazy and move the HWSTAM into its own function
v3: Mask off all HWSP writes on driver unload and engine cleanup.
v4: And what about the physical hwsp?
v5: No, engine->init_hw() is not called from driver_init_hw(), don't be
daft. Really scrub HWSTAM as early as we can in driver_init_mmio()
v6: Rename set_hwsp as it was setting the mask not the hwsp register.
v7: Ville pointed out that although vcs(bsd) was introduced for g4x/ilk,
per-engine HWSTAM was not introduced until gen6!

drm-next

"nothing major this time, mostly some cleanups that were found on the
way of reworking the code in preparation for new feature additions."
Small conflict in drivers/gpu/drm/etnaviv/etnaviv_drv.c because
drm-misc-next also has a patch to switch over to _put() functions.

The etnaviv_gpu header only needs to know about the pointer types, so
replace by a forward declaration and only include the headers where needed.

The only event function that is called from IRQ context is event_free,
which is already using atomic bitmap operations, so we can avoid taking
the event spinlock in this function completely. As other the other
functions still using the event spinlock are all called from normal
process context, we can avoid disabling IRQs while holding the spinlock.

When the pipe_config's update_pipe flag is set we may need to update the
panel fitting settings. On GEN9+ this means we need to update the crtc's
scaler settings.
This fixes the following WARN_ON, during i915 loading on an Asrock
B150M Pro4S/D3 board with an i5-6500 CPU / graphics:
[drm:pipe_config_err [i915]] *ERROR* mismatch in pch_pfit.enabled
(expected no, found yes)
pipe state doesn't match!
WARNING: CPU: 3 PID: 305 at drivers/gpu/drm/i915/intel_display.c:12084
With line 12084 being the I915_STATE_WARN call inside the
"if (!intel_pipe_config_compare())" block in verify_crtc_state().
On this board with 2 1920x1080 monitors connected over HDMI the GOP
initializes both monitors at 1920x1080 and despite no scaling being
necessary configures a scaler for one of them.
When booting with fastboot=1 on the initial modeset needs_modeset will
be false while update_pipe is true. Since we were not calling
skl_update_scaler_crtc() in this case we would leave the scaler enabled
causing this error.

The drm_ati_pcigart_init() function was originally suppose to return one
on success and zero on failure, but these days it returns a mix of
zero, one and -ENOMEM on failure.
This patch cleans it up and modifies the caller so now the function
returns zero on success and negative error codes on failure.

The drm_mode_create_tile_group() is only called from
drm_parse_tiled_block() and the caller expects it to return a NULL on
error. In other words, this function should match
drm_mode_get_tile_group().

DSC can be supported per DP connector. This patch adds a per connector
debugfs node to expose DSC support capability by the kernel.
The same node can be used from userspace to force DSC enable.
force_dsc_en written through this debugfs node is used to force
DSC even for lower resolutions.
Credits to Ville Syrjala for suggesting the proper locks to be used
and to Lyude Paul for explaining how to use them in this context
v8:
* Add else if (ret) for drm_modeset_lock (Lyude)
v7:
* Get crtc, crtc_state from connector atomic state
and add proper locks and backoff (Ville, Chris Wilson, Lyude)
(Suggested-by: Ville Syrjala <ville.syrjala@linux.intel.com>)
* Use %zu for printing size_t variable (Lyude)
v6:
* Read fec_capable only for non edp (Manasi)
v5:
* Name it dsc sink support and also add
fec support in the same node (Ville)
v4:
* Add missed connector_status check (Manasi)
* Create i915_dsc_support node only for Gen >=10 (manasi)
* Access intel_dp->dsc_dpcd only if its not NULL (Manasi)
v3:
* Combine Force_dsc_en with this patch (Ville)
v2:
* Use kstrtobool_from_user to avoid explicit error checking (Lyude)
* Rebase on drm-tip (Manasi)
