drm/plane: Remove drm_plane_init()

Open-code drm_plane_init() and remove the function from DRM. The
implementation of drm_plane_init() is a simple wrapper around a call
to drm_universal_plane_init(), so drivers can just use that instead.

register acpi_video# backlight devices when supported.

Once the drm/kms driver then loaded later and possibly registered
a native backlight device then the drivers/acpi/video_detect.c code
unregistered the acpi_video0 device to avoid there being 2 backlight

This means that userspace used to briefly see 2 devices and the
disappearing of acpi_video0 after a brief time confuses the systemd
backlight level save/restore code, see e.g.:
https://bbs.archlinux.org/viewtopic.php?id=269920

To fix this the ACPI video code has been modified to make backlight class
device registration a separate step, relying on the drm/kms driver to
ask for the acpi_video backlight registration after it is done setting up
its native backlight device.

Add a call to the new acpi_video_register_backlight() function after
setting up the gma500's native backlight, so that the acpi_video backlight
device gets registered on systems where the gma500's native backlight

drm/gma500: Rewrite power management code

Rewrite the power.c code. For some reason this was doing locking +
refcounting + state (suspended or not) bookkeeping all by itself.

But there is no reason for this, this is all taken care of by
the runtime-pm core, through pm_runtime_get()/_put().

Besides this not being necessary the DIY code is also quite weird/
buggy in some places. E.g. power_begin() would manually do a resume
when not resumed already and force_on=true, followed by a
pm_runtime_get(), which will cause a call to gma_power_resume() to
get scheduled which would redo the entire resume again. Which can
all be replaced by a single pm_runtime_get_sync() call.

Note that this is just a cleanup, this does not actually fix
the (disabled through #if 0) runtime-pm support. It does now call
pm_runtime_enable(), but only after doing a pm_runtime_get() at
probe-time, so the device is never runtime suspended.

Doing this permanent get() + enable() instead of not calling
enable() at all is necessary for the pm_runtime_get_if_in_use() call
in gma_power_begin() to work properly.

Note this also removes the gma_power_is_on() call a check like this
without actually holding a reference is always racy, so it is a bad
idea (and therefor has no pm_runtime_foo() equivalent).

The 2 code paths which were using gma_power_is_on() are actually both
guaranteed to only run when the device is powered-on so the 2 checks
can simply be dropped.

This fixes 2 problems with the IRQ handling:

1. gma_power_off() calls gma_irq_uninstall() which does a free_irq(), but
   gma_power_on() called gma_irq_preinstall() + gma_irq_postinstall() which

   Atom N2600, cedarview) netbook.

   Cederview uses MSI interrupts and it seems that the BIOS re-configures
   things back to normal APIC based interrupts during S3 suspend. There is
   some MSI PCI-config registers save/restore code which tries to deal with
   this, but on the Packard Bell Dot SC this is not sufficient to restore

2 years agodrm/vc4: hdmi: Reset link on hotplug
Maxime Ripard [Mon, 29 Aug 2022 13:47:30 +0000 (15:47 +0200)]
drm/vc4: hdmi: Reset link on hotplug

During a hotplug cycle (such as a TV going out of suspend, or when the
cable is disconnected and reconnected), the expectation is that the same
state used before the disconnection is reused until the next commit.

However, the HDMI scrambling requires that some flags are set in the
monitor, and those flags are very likely to be reset when the cable has
been disconnected. This will thus result in a blank display, even if the
display pipeline configuration hasn't been modified or is in the exact
same state.

The solution we've had so far is to enable the scrambling-related bits
again on reconnection, but the HDMI 2.0 specification (Section 6.1.3.1 -
Scrambling Control) requires that the scrambling enable bit is set
before sending any scrambled video signal. Using that solution thus
breaks that expectation.

The solution used by i915 is to do a full modeset on the connector so
that we disable the video signal, enable the scrambling bit, and enable
the video signal again.

As such, we took that code and plugged it into vc4. It probably could
have been turned into an helper, but it proved to be difficult for
several reasons:

  * i915 has fairly different structures than simpler KMS drivers such
    as vc4, so doing some code that works with both proved to be
    difficult;

  * Other simpler drivers could reuse some of it (tegra, dw-hdmi), but
    it would still require to move some parameters currently stored in
    private structure that are needed to compute whether the scrambling
    is needed or not, and then inform the driver that it needs to be
    enabled. Some of those parameters are already in core structures
    (drm_display_mode, drm_display_info, bpc), but the output format
    isnt't. Adding it is fairly challenging since unlike the TMDS char
    rate or mode, there's no consensus on what format to pick in
    drivers, so it's not possible to write some generic code that can
    depend on it.

For these reasons, we chose to duplicate the code for now, until someone
else really needs it as well, in which case we will be able to convert
it into a generic helper.

However, using it in the detect hook was creating a reentrency issue
with CEC code. Indeed, calling cec_s_phys_addr_from_edid from detect
might call the CEC adap_enable hook with the lock held, eventually
resulting in a deadlock.

Since we didn't really need to protect anything at the moment in the CEC
code, the decision was made to ignore the mutex in those CEC hooks,
working around the issue.

However, we can have the same thing happening if we end up triggering a
mode set from the detect callback, for example using
drm_atomic_helper_connector_hdmi_reset_link().

Since we don't really need to protect anything in detect either, let's
just drop the lock in detect, and add it again in CEC.

UAPI Changes:

- Revert "drm/i915/dg2: Add preemption changes for Wa_14015141709"

  The intent of Wa_14015141709 was to inform us that userspace can no
  longer control object-level preemption as it has on past platforms
  (i.e., by twiddling register bit CS_CHICKEN1[0]).  The description of
  the workaround in the spec wasn't terribly well-written, and when we
  requested clarification from the hardware teams we were told that on the
  kernel side we should also probably stop setting
  FF_SLICE_CS_CHICKEN1[14], which is the register bit that directs the
  hardware to honor the settings in per-context register CS_CHICKEN1.  It
  turns out that this guidance about FF_SLICE_CS_CHICKEN1[14] was a
  mistake; even though CS_CHICKEN1[0] is non-operational and useless to
  userspace, there are other bits in the register that do still work and
  might need to be adjusted by userspace in the future (e.g., to implement
  other workarounds that show up).  If we don't set
  FF_SLICE_CS_CHICKEN1[14] in i915, then those future workarounds would
  not take effect.

2 years agodrm/udl: Fix inconsistent urbs.count value during udl_free_urb_list()
Takashi Iwai [Thu, 8 Sep 2022 09:51:13 +0000 (11:51 +0200)]
drm/udl: Fix inconsistent urbs.count value during udl_free_urb_list()

In the current design, udl_get_urb() may be called asynchronously
during the driver freeing its URL list via udl_free_urb_list().
The problem is that the sync is determined by comparing the urbs.count
and urbs.available fields, while we clear urbs.count field only once
after udl_free_urb_list() finishes, i.e. during udl_free_urb_list(),
the state becomes inconsistent.

For fixing this inconsistency and also for hardening the locking
scheme, this patch does a slight refactoring of the code around
udl_get_urb() and udl_free_urb_list().  Now urbs.count is updated in
the same spinlock at extracting a URB from the list in
udl_free_url_list().

changes to 'true'. Taking this into account when considering a mode
switch restores the display mode.

The bug is reproducable by using Gnome with udl and observing the
adapter's suspend/resume behavior.

Actually, the whole check added in udl_simple_display_pipe_enable()
about the crtc_state->mode_changed was bogus.  We should drop the
whole check and always apply the mode change in this function.

2 years agodrm/ssd130x: Replace simple display helpers with the atomic helpers
Javier Martinez Canillas [Mon, 5 Sep 2022 22:27:59 +0000 (00:27 +0200)]
drm/ssd130x: Replace simple display helpers with the atomic helpers

The simple display pipeline is a set of helpers that can be used by DRM
drivers to avoid dealing with all the needed components and just define
a few functions to operate a simple display device with one full-screen
scanout buffer feeding a single output.

But it is arguable that this provides the correct level of abstraction
for simple drivers, and recently some have been ported from using these
simple display helpers to use the regular atomic helpers instead.

The rationale for this is that the simple display pipeline helpers don't
hide that much of the DRM complexity, while adding an indirection layer
that conflates the concepts of CRTCs and planes. This makes the helpers
less flexible and harder to be reused among different graphics drivers.

Also, for simple drivers, using the full atomic helpers doesn't require
a lot of additional code. So adding a simple display pipeline layer may
not be worth it.

For these reasons, let's follow that trend and make ssd130x a plain DRM
driver that creates its own primary plane, CRTC, enconder and connector.
