Initial support of HID-BPF (Benjamin Tissoires)

The history is a little long for this series, as it was intended to be
sent for v6.2. However some last minute issues forced us to postpone it
to v6.3.

Conflicts:
* drivers/hid/i2c-hid/Kconfig:
  commit bf7660dab30d ("HID: stop drivers from selecting CONFIG_HID")
  conflicts with commit 2afac81dd165 ("HID: fix I2C_HID not selected
  when I2C_HID_OF_ELAN is")
  the resolution is simple enough: just drop the "default" and "select"

  touchscreen as either 3.3V or 1.8V. Presumably this means that the
  touchscreen has its own way internally to make or deal with 1.8V
  signals when it's configured for 1.8V IO.

NOTE: you've got to look very carefully at the datasheet for the
touchscreen to see that the above bullets are true. Specifically, the
datasheet shows a signal called VDDIO and one might think that this is
where a mainboard would provide VDDIO to the touchscreen. Upon closer
inspection, however, a footnote can be found that says "When VDDIO is
left floating, the logic level is 1.8V [...]; when VDDIO is connected
to AVDD, the logic level is AVDD.". Thus the VDDIO pin on the
touchscreen IC is actually a selector and not a pin whre the mainboard
would pass a reference voltage.

The fact that the touchscreen isn't supplied 1.8V by the mainboard
means that when I originally submitted bindings for these touchscreens
I only listed the 3.3V rail in the bindings. It can be noted that the
original bindings and driver were added for sc7180-trogdor boards and
these boards all use 3.3V IO via a level shifter on the mainboard.

It turns out that with sc7280-herobrine-evoker, we've got a bit of a
strange monkey on our hands. Due to some very interesting but
(unfortunately) set-in-stone hardware design, we are doing 1.8V IO to
the touchscreen but we _also_ have some extra buffers on the mainboard
that need to be powered up to make the IO lines work. After much
pondering about this, it seems like the best way to handle this is to
add an optional "mainboard-vddio" rail to the bindings that is used to
power up the buffers. Specifically, the fact that the touchscreen
datasheet documents that its IOs can be at a different voltage level
than its main power rail means that there truly are two voltage rails
associated with the touchscreen, even if we don't actually provide the
IO rail to it. Thus it doesn't feel absurd for the DT node on the host
to have a 1.8V rail to power up anything related to its 1.8V logic.

15 months agoHID: i2c-hid: goodix: Stop tying the reset line to the regulator
Douglas Anderson [Tue, 7 Feb 2023 02:48:13 +0000 (18:48 -0800)]
HID: i2c-hid: goodix: Stop tying the reset line to the regulator

In commit 18eeef46d359 ("HID: i2c-hid: goodix: Tie the reset line to
true state of the regulator"), we started tying the reset line of
Goodix touchscreens to the regulator.

The primary motivation for that patch was some pre-production hardware
(specifically sc7180-trogdor-homestar) where it was proposed to hook
the touchscreen's main 3.3V power rail to an always-on supply. In such
a case, when we turned "off" the touchscreen in Linux it was bad to
assert the "reset" GPIO because that was causing a power drain. The
patch accomplished that goal and did it in a general sort of way that
didn't require special properties to be added in the device tree for
homestar.

It turns out that the design of using an always-on power rail for the
touchscreen was rejected soon after the patch was written and long
before sc7180-trogdor-homestar went into production. The final design
of homestar actually fully separates the rail for the touchscreen and
the display panel and both can be powered off and on. That means that
the original motivation for the feature is gone.

There are 3 other users of the goodix i2c-hid driver in mainline.

I'll first talk about 2 of the other users in mainline: coachz and
mrbland. On both coachz and mrbland the touchscreen power and panel
power _are_ shared. That means that the patch to tie the reset line to
the true state of the regulator _is_ doing something on those
boards. Specifically, the patch reduced power consumption by tens of
mA in the case where we turned the touchscreen off but left the panel
on. Other than saving a small bit of power, the patch wasn't truly
necessary. That being said, even though a small bit of power was saved
in the state of "panel on + touchscreen off", that's not actually a
state we ever expect to be in, except perhaps for very short periods
of time at boot or during suspend/resume. Thus, the patch is truly not
necessary. It should be further noted that, as documented in the
original patch, the current code still didn't optimize power for every
corner case of the "shared rail" situation.

The last user in mainline was very recently added: evoker. Evoker is
actually the motivation for me removing this bit of code. It turns out
that for evoker we need to manage a second power rail for IO to the
touchscreen. Trying to fit the management of this IO rail into the
regulator notifiers turns out to be extremely hard. To avoid lockdep
splats you shouldn't enable/disable other regulators in regulator
notifiers and trying to find a way around this was going to be fairly
difficult.

Given the lack of any true motivation to tie the reset line to the
regulator, lets go back to the simpler days and remove the code. This
is, effectively, a revert of commit bdbc65eb77ee ("HID: i2c-hid:
goodix: Fix a lockdep splat"), commit 25ddd7cfc582 ("HID: i2c-hid:
goodix: Use the devm variant of regulator_register_notifier()"), and
commit 18eeef46d359 ("HID: i2c-hid: goodix: Tie the reset line to true
state of the regulator").

HID: retain initial quirks set up when creating HID devices

In certain circumstances, such as when creating I2C-connected HID
devices, we want to pass and retain some quirks (axis inversion, etc).
The source of such quirks may be device tree, or DMI data, or something
else not readily available to the HID core itself and therefore cannot
be reconstructed easily. To allow this, introduce "initial_quirks" field
in hid_device structure and use it when determining the final set of
quirks.

This fixes the problem with i2c-hid setting up device-tree sourced
quirks too late and losing them on device rebind, and also allows to
sever the tie between hid-code and i2c-hid when applying DMI-based

HID: use standard debug APIs

The custom "debug" module parameter is fairly inflexible.
It can only manage debugging for all calls dbg_hid() at the same time.

Furthermore it creates a mismatch between calls to hid_dbg() which can
be managed by CONFIG_DYNAMIC_DEBUG and dbg_hid() which is managed by the
module parameter.

Furthermore the change to pr_debug() allows the debugging statements to
be completely compiled-out if desired.

HV: hv_balloon: fix memory leak with using debugfs_lookup()

When calling debugfs_lookup() the result must have dput() called on it,
otherwise the memory will leak over time.  To make things simpler, just
call debugfs_lookup_and_remove() instead which handles all of the logic
at once.

of/address: Return an error when no valid dma-ranges are found

Commit 7a8b64d17e35 ("of/address: use range parser for of_dma_get_range")
converted the parsing of dma-range properties to use code shared with the
PCI range parser. The intent was to introduce no functional changes however
in the case where we fail to translate the first resource instead of
returning -EINVAL the new code we return 0. Restore the previous behaviour
by returning an error if we find no valid ranges, the original code only
handled the first range but subsequently support for parsing all supplied
ranges was added.

This avoids confusing code using the parsed ranges which doesn't expect to
successfully parse ranges but have only a list terminator returned, this
fixes breakage with so far as I can tell all DMA for on SoC devices on the
Socionext Synquacer platform which has a firmware supplied DT. A bisect
identified the original conversion as triggering the issues there.

tracing: Fix poll() and select() do not work on per_cpu trace_pipe and trace_pipe_raw

poll() and select() on per_cpu trace_pipe and trace_pipe_raw do not work
since kernel 6.1-rc6. This issue is seen after the commit
42fb0a1e84ff525ebe560e2baf9451ab69127e2b ("tracing/ring-buffer: Have
polling block on watermark").

This issue is firstly detected and reported, when testing the CXL error
events in the rasdaemon and also erified using the test application for poll()
and select().

This issue occurs for the per_cpu case, when calling the ring_buffer_poll_wait(),
in kernel/trace/ring_buffer.c, with the buffer_percent > 0 and then wait until the
percentage of pages are available. The default value set for the buffer_percent is 50
in the kernel/trace/trace.c.

As a fix, allow userspace application could set buffer_percent as 0 through
the buffer_percent_fops, so that the task will wake up as soon as data is added
to any of the specific cpu buffer.
