[PATCH v3 0/2] ACPI serdev support

[PATCH v3 0/2] ACPI serdev support

[Frédéric Danis]

Add ACPI support for serial attached devices.

Currently, serial devices are not set as enumerated during ACPI scan for SPI
or i2c buses (but not for UART). This should also be done for UART serial
devices.
I renamed *spi_i2c_slave* to *serial_bus_slave* to reflect this.

This needs Johan Hovold's "serdev: fix registration of second slave" patch.

Tested on T100TA with Broadcom BCM2E39.

Since v2:
  - Remove ctrl->serdev set to NULL in acpi_serdev_register_device() in favor
    of Johan's patch
  - Fallback to ctrl->serdev check when acpi_walk_namespace() returns an error
    to prevent memory leak
  - Remove a change in dev_dbg() call in serdev_controller_add(), this will
    be done in separate patch
Since v1:
  - Check if a serdev device as been allocated during acpi_walk_namespace() to
    prevent serdev controller registration instead of the tty-class device.
  - Reword dev_dbg() strings replacing Serial by serdev
  - Removing redundant "serdev%d" in dev_dbg() calls in serdev_controller_add()
Since RFC:
  - Add or reword commit messages
  - Rename *serial_slave* to *serial_bus_slave*
  - Add specific check for Apple in acpi_is_serial_bus_slave(), thanks to
    Lukas Wunner
  - Update comment in acpi_default_enumeration()
  - Remove patch 3 "Bluetooth: hci_bcm: Add ACPI serdev support for BCM2E39"
    in favor of patches from Hans de Goede

[PATCH v3 2/2] ACPI / scan: Fix enumeration for special UART devices

[Frédéric Danis]

UART devices is expected to be enumerated by SerDev subsystem.

During ACPI scan, serial devices behind SPI, I2C or UART buses are not
enumerated, allowing them to be enumerated by their respective parents.

Rename *spi_i2c_slave* to *serial_bus_slave* as this will be used for serial
devices on serial buses (SPI, I2C or UART).

On Macs an empty ResourceTemplate is returned for uart slaves.
Instead the device properties "baud", "parity", "dataBits", "stopBits" are
provided. Add a check for "baud" in acpi_is_serial_bus_slave().

This patch appears to break UART probing in ACPI on xgene based
plaforms.

This seems to be related to 
https://bugzilla.redhat.com/show_bug.cgi?id=1531140
Am I correct?

The SerDev support should allow UART to appear as tty device if not used 
by an underlying component (cf. tty_port_register_device_attr() in 
drivers/tty/tty_port.c).

AFAIU, there is no internal device attached to this serial port.
Is it possible to get complete ACPI DSDT?

Is SerDev enabled on this device?
Boot logs with SerDev debug traces enabled can be useful to understand 
what happens.

Regards,

Fred

This seems to be related to 
https://bugzilla.redhat.com/show_bug.cgi?id=1531140
Am I correct?

The SerDev support should allow UART to appear as tty device if not used 
by an underlying component (cf. tty_port_register_device_attr() in 
drivers/tty/tty_port.c).

AFAIU, there is no internal device attached to this serial port.
Is it possible to get complete ACPI DSDT?

Is SerDev enabled on this device?
Boot logs with SerDev debug traces enabled can be useful to understand 
what happens.

Regards,

Fred

Ahah that is the same thing I'm pretty certain, my googling did not turn 
that up.

#define DEBUG in serdev/core.c does not seem to produce much output. But 
attached bootlog anyway.

In theory this series could go in through the acpi-tree without my
fix. It would only affect an error case where an unlikely failure to
register an ACPI serdev device, would prevent the tty-class device from
being registered instead of the controller. That is, something we can
live with until this all converges in 4.15-rc1 if needed.

That said, I think we should consider taking all serdev changes, and
therefore also the ACPI patch, through the tty tree instead in order to
avoid merge conflicts. Rafael?

OK

Please feel free to add

Acked-by: Rafael J. Wysocki <rafael.j.wysocki-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

to the ACPI core change.

And I will assume that this series will go in via the tty tree.

you have to take these two patches now via the TTY tree now. In case you already marked them as someone else problem ;)

I just realised that we cannot merge this series (the second acpi patch)
until the hci_intel driver gains serdev support or otherwise PM will
break for those devices.

Specifically, the hci_intel driver uses similar hacks as the hci_bcm
driver does for PM, so we need something like Hans's hci_bcm series also
for hci_intel before we can do the switch.

Hopefully there are no more of these...

Hmm, I've never actually seen any hardware use an intel BT HCI connected
to a serdev, but I guess people did not write that code for fun, so those
do exist ?

they are all ACPI based and could now start using serdev. Previously they were all driven by btattach.

I understand, I was just wondering if anyone is aware of any hardware
actually using Intel BT devices in this manner, because it is going
to be tricky to do a similar series if we cannot test it.

Yeah this driver supports Lightning-Peak iBT 3.0 UART controller.
I remember this controller comes (at least) with Atom x3-c3440 / x3-c3445
SoCs.
However I don't have the hardware anymore.

Ah, those are the Rockchip manufactured Atom based SoCs which
come with Mali graphics, I don't think anyone is trying to run
mainline on those and not a whole lot of those have shipped to
begin with (the line has been canceled).

I've an Apollo Lake based laptop with Intel Bluetooth, I just
checked and that is simply using USB.

So I don't think we are actually going to break anything by
just moving forward as planned. This reminds me of the axp288
driver where Intel's "embedded" engineering team upstreamed
parts of the axp288 PMIC code, but in a way where the driver
could not work as it would not load with platform_data which
was never provided by the mainline kernel.

As such it might actually be good to break this and if no-one
complains we can just remove the hci_intel.c code altogether.

The alternative would be to revert 2 if the 3 patches of
my last series for making the BT on the GPD win / pocket
(and likely other devices) work in uart mode. Then someone
(me?) would need to do a completely untested series for
hci_intel.c, and get that + reverts of the reverts into 4.16,
which is not the best way forward IMHO.

I think we can go forward with what we have. I am not going to remove hci_intel.c since the firmware loading code etc. is pretty generic to all Intel UART based chips. However we just take the PM pieces out or maybe someone is going to fix them.

I am not doing that. We have to make progress towards serdev. So if things really turn out badly, then we have to deal with it, but that should not hold up getting things in the direction this needs to go.

Note that hci_intel used the platform hack for the reset line and host
wake-up irq. And as the reset line appears to be required when using
ACPI, we'd definitely find out eventually if anyone is using such
devices as they would fail to even power on.

As long as we know what we are breaking.

At least that's what it looks like. 

It was added by Loic Poulain in commit 1ab1f239bf17 ("Bluetooth:
hci_intel: Add support for platform driver") two years ago and the
ACPI-match table has an entry for "INT33E1".
