[PATCH 0/2] ACPI serdev support

[PATCH 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.

For hci_bcm, this needs Hans de Goede's "Bluetooth: hci_bcm: Add (runtime)pm
support to the serdev drv" patches to work.

Tested on T100TA with Broadcom BCM2E39.

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 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().

So just to reiterate what I just mentioned in a comment to one of Hans's
hci_bcm patches:

This one would silently break PM for such devices on any system which
does not have serdev enabled (as the corresponding platform devices
would no longer be registered). And with serdev enabled, hciattach
(btattach) would start failing as the tty device would no longer be
registered (but I assume everyone is aware of that, and fine with it, by
now).

Perhaps the hci_bcm driver should start depending on
SERIAL_DEV_CTRL_TTYPORT when ACPI is enabled?

ACPI and DT both need SERIAL_DEV_CTRL_TTYPORT to work properly,
since SERIAL_DEV_CTRL_TTYPORT is the only controller implemented
for serdev. If any other controller is implemented that one could
also be used.

I wonder if we should just hide SERIAL_DEV_CTRL_TTYPORT and enable
it together with SERDEV. I suspect that we won't see any other
controller (it would be a UART device, that is not registered as
tty device) in the next few years and the extra option seems to
confuse people.

I wonder if we should just default SERIAL_DEV_CTRL_TTYPORT=y when DT or ACPI is enabled. Then no driver would have to select or depend on it.

This is not related to DT/ACPI. SERIAL_DEV_CTRL_TTYPORT is a serdev
controller driver, that registers serdev controller devices for each
tty. It will also be used by clients, that are registered via board
code.

Not for hci_bcm, right? This particular driver specifically depends on
SERIAL_DEV_CTRL_TTYPORT for the ACPI devices and not just any (future)
serdev controller (or currently working systems soon breaks silently).

I don't think the same is true for the DT case where we do not already
have child nodes defined in firmware (and in fact, this driver did not
really support DT before serdev).

I agree that it is somewhat confusing. But now that we have both,
perhaps simply having SERIAL_DEV_CTRL_TTYPORT default to "y" when
SERIAL_DEV_BUS is selected could be a compromise. The Kconfig entry
might need to be amended as well (e.g. if only to mention that you need
to select a controller as well).

And the bluetooth uart drivers already depend on SERIAL_DEV_BUS.

The serdev ACPI support has been added to the core and not to
the ttyport and the hci_bcm driver only uses functions from the
core. As far as I can see the ACPI part would also work fine with
a different serdev controller.

Of course DT and ACPI currently require SERIAL_DEV_CTRL_TTYPORT,
since it's the only serdev controller implementation. Also it
covers most use cases. When SERIAL_DEV_BUS is selected it's
very likely, that you also want SERIAL_DEV_CTRL_TTYPORT.

I think we should at least add a default "y" if SERIAL_DEV_BUS.

> And the bluetooth uart drivers already depend on SERIAL_DEV_BUS.

Yes and that's the correct dependency. They only need the serdev
core and controller. The only reason they do not work without
SERIAL_DEV_CTRL_TTYPORT is, that there won't be any serdev
controller.

Note, that the default "y" if SERIAL_DEV_BUS in SERIAL_DEV_CTRL_TTYPORT's
config entry is only a partial fix. There is still the problem,
that SERIAL_DEV_CTRL_TTYPORT can only be enabled if SERIAL_DEV_BUS
is configured builtin. This is a limitation of the ttyport
implementation, that hooks into builtin TTY core code.

Indeed, but you need SERIAL_DEV_CTRL_TTYPORT to avoid silently breaking
current ACPI setups which breaks when this patch is applied (as these
devices all hang off of common serial ports managed by serial core).

In general, yes. Again, the only exception would be hci_bcm to avoid
breaking current setups without people noticing.

I'm not saying it's a fix, but it is a sane default. I'm preparing a
patch also amending the Kconfig entries, and we can take it from there.

I submitted a patch amending the serdev Kconfig entries and making
SERIAL_DEV_CTRL_TTYPORT default to Y when serdev support has been
chosen.

While that hopefully reduces the confusion regarding the Kconfig options
somewhat, it's not really a fix for the potential silent hci_bcm
regression that could result from this patch.

[ The problem being that hci-attach would still succeed, but PM would be
broken, when SERIAL_DEV_CTRL_TTYPORT is not set. ]

I mentioned that making HCI_BCM depend on SERIAL_DEV_CTRL_TTYPORT might
be used to avoid this situation, although it is on some level is
conceptually wrong to describe runtime dependencies in Kconfig (cf.
having a USB device driver, depend on a particular host controller
rather than just USB support).

I'll write something like that up in a patch for Bluetooth and you can
decide if you want to apply it to remedy this particular situation,
though.

I submitted a patch amending the serdev Kconfig entries and making
SERIAL_DEV_CTRL_TTYPORT default to Y when serdev support has been
chosen.

While that hopefully reduces the confusion regarding the Kconfig options
somewhat, it's not really a fix for the potential silent hci_bcm
regression that could result from this patch.

[ The problem being that hci-attach would still succeed, but PM would be
broken, when SERIAL_DEV_CTRL_TTYPORT is not set. ]

I mentioned that making HCI_BCM depend on SERIAL_DEV_CTRL_TTYPORT might
be used to avoid this situation, although it is on some level is
conceptually wrong to describe runtime dependencies in Kconfig (cf.
having a USB device driver, depend on a particular host controller
rather than just USB support).

I'll write something like that up in a patch for Bluetooth and you can
decide if you want to apply it to remedy this particular situation,
though.

I already applied Hans’ patch series to bluetooth-next tree. And I have no objections or comments for these changes. They should be reviewed and acked by the appropriate maintainers as well, but from my side this looks good.

Acked-by: Marcel Holtmann <marcel@holtmann.org>

What we should discuss on how we get them upstream since besides the Bluetooth subsystem, they cover ACPI and TTY subsystems.

Hi Marcel,

I've tested these two patches along with the nine patches (plus revert patch) from Hans's series but cannot get bluetooth to work on some of my devices using these two patches as is, specifically on MINIX Z83-4 based PCs. 

In order for bluetooth to function on these devices I submitted the patch 'Bluetooth: BCM: Add support for MINIX Z83-4 based devices' as they require the trigger type IRQF_TRIGGER_FALLING. With Hans's new patch series I've had to modify the patch which I've resubmitted as version 2. However when I apply the second patch from Fred's series 'ACPI / scan: Fix enumeration for special UART devices' I have found the bluetooth device (BCM2EA4) is no longer enumerated. Specifically I've found that the removal of the check 'if (ares->data.common_serial_bus.type != ACPI_RESOURCE_SERIAL_TYPE_UART)' causes this failure and if I re-add the 'if' statement then the device is loaded. However a 'btattach' is still required for functioning bluetooth.

In terms on applying the patches I have some questions. 

Like Hans I too would like one of my patches to be applied to v4.14. A lot of people have been waiting to get bluetooth working on the MINIX Z83-4 family of devices so is it possible to get my original (resend) patch for bluetooth on MINIX Z83-4 based devices applied to v4.14? If so and assuming the nine patches from Hans go into v4.15 I can then send an additional patch to extend his second patch (Bluetooth: hci_bcm: Fix setting of irq trigger type) to delete the extra line '.driver_data = &acpi_active_low,'. 

If the original (resend) version of my patch for MINIX Z83-4 cannot be applied to v4.14 then I would like to request that my second version of my patch for MINIX Z83-4 based devices be applied to bluetooth-next tree so that they are included in v4.15.

Finally I would like to request some help in addressing the issue caused by Fred's 'Fix enumeration for special UART devices' patch so as to prevent a regression.

Regards,
Ian

It seems normal to me that BCM2EA4 is no more enumerated at ACPI level 
as this is moved to serdev.
When removing 'if (ares->data.common_serial_bus.type != 
ACPI_RESOURCE_SERIAL_TYPE_UART)' you stop the serdev module finding the 
Serial UART information. In this case it will not register the device 
and it will fall back to previous behavior needing to use btattach to 
setup Bluetooth.

Can you share:
- btattach you are currently using,
- dmesg with with dynamic debug enabled for serdev and hci_uart modules 
during boot (with Hans's patches, your MINIX Z83-4 patches and mine 
patches).

Hi Fred,

I've attached four (text) files:

1. btattach.txt - Details of the 'bluez' package that contains the
'btattach' I'm using.
2. dmesg.txt - 'dmesg' with with dynamic debug enabled for serdev and
hci_uart modules. This doesn't seem to show much so have I provided
what you wanted?
3. gitlog.txt - First few commits from the git log showing the kernel
patches used to build the kernel (sent just for clarity).
4. working.txt - An extract from 'dmesg' when BCM2EA4 is enumerated
from a kernel patched with the 'if' statement refered to above.

Regards,
Ian

Which tty is used for btattach?
Is this tty existing in /dev?

I took a look at dmesg.txt and I did not find any trace related to serdev.
On the T100, where ttyS4 is used for Bluetooth, I can see the following 
traces:
   [   11.732347] serial serial0: allocated controller 
0xffff880036229000 id 0
   [   11.732470] serial serial0-0: device serial0-0 registered
   [   11.732475] serial serial0: serdev0 registered: dev:ffff880036229000
   [   11.732478] serial serial0: tty port ttyS4 registered

If serdev registration failed you should at least get something like:
     serdev0 no devices registered: of:<> acpi:<>

So, just to be sure, is SERIAL_DEV_BUS and SERIAL_DEV_CTRL_TTYPORT 
enabled in your kernel?

Regards,

Fred

Hi Fred,

My config actually had SERIAL_DEV_BUS set as 'm' so SERIAL_DEV_CTRL_TTYPORT was (forced) unset. If I set them both everything now works (see attached dmesg).

I've submitted a new patch to update drivers/tty/serdev/Kconfig for ACPI support as the current Kconfig for serdev is not really compatible when adding ACPI support. If SERIAL_DEV_BUS is set as 'm' then the ACPI support does not work when built as a module as it requires config SERIAL_DEV_CTRL_TTYPORT to be set as you stated. If you force SERIAL_DEV_CTRL_TTYPORT to be set then a compilation error results. So I suggest that if SERIAL_DEV_BUS is selected then serdev is compiled into the kernel so that config SERIAL_DEV_CTRL_TTYPORT can be selected and set if requiring ACPI support.

Regards,
Ian

[PATCH 1/2] serdev: Add ACPI support

[Frédéric Danis]

This patch allows SerDev module to manage serial devices declared as
attached to an UART in ACPI table.

acpi_serdev_add_device() callback will only take into account entries
without enumerated flag set. This flags is set for all entries during
ACPI scan, except for SPI and I2C serial devices, and for UART with
2nd patch in the series.

so how do we get these changes upstream? If the serdev changes alone do not cause any harm, I am almost proposing taking them through bluetooth-next tree and only leave only the ACPI change to the ACPI maintainers.

Greg, any thoughts?

That would be fine by me.  I can take the serdev patch too, though.

having both patches go via ACPI tree might be simplest. Greg, any objections from you?

What if there are no slaves defined? I'm not very familiar with the ACPI
helpers, but from a quick look it seems you'd then end up returning zero
here which would cause the serdev controller to be registered instead of
the tty-class device.

[ And if I'm mistaken, you do want to suppress that error message for
when there are no slaves defined. ]

"serdev%d" is redundant here as you're using dev_dbg (which will print
the device name).

Hmm, I see it's already used here. No need to follow that example
though.

Some of the above are minor nits that can be addressed by a follow-up
patch indeed, but the handling of nodes with no child devices needs to
be correct (or you could end up breaking normal serial-port support).

that sounds good to me as well. Lets get this feature into the ACPI tree since I am going to push Hans’ patches into bluetooth-next as soon as he re-submits the missing ID change. That hopefully gives us then fully serdev support for ACPI and DT when it comes to Broadcom Bluetooth controllers.

Next step is to convert the Intel driver to also use ACPI based serdev :)

And for the brave, I think there are Realtek based systems using ACPI as well.

What I was wondering the other day is if we need a lsserdev tool or some integration in lshw to be able to debug what serdev devices and ID are present. The lsusb and /sys/kernel/debug/usb/devices is just super powerful and easy when it comes to figuring out what people have in their system. Maybe /sys/kernel/debug/serdev/devices could be helpful as well. Just thinking out loud here.

But with Hans's work these devices should continue to function using the
platform-device hacks until the ACPI patch eventually lands in Linus's
tree (via the acpi tree).

Yeah, maybe. Since you'd typically only have small number of serdev
devices (say, max 4), using /sys/bus/serial/devices directly should not
be too bad meanwhile. Not that much common information we can expose
either, at least not in comparison to USB. But I'll keep it mind. :)

Yes in the interim, if you have 'tree' installed then for example

It is a bit shabby when there is nothing to report

Some review comments you received on this series should be addressed
IMO, so I'm expecting an update of it.

When sending the next version, please add all of the tags you've
already received on it.
