*** This bug has been marked as a duplicate of bug 69011 ***
Comment 4 Bastien Nocera 2014-09-09 09:40:25 UTC 
The patches in bug 69011 don't actually help, FWIW.
Comment 5 Lan Tianyu 2014-09-09 09:48:15 UTC 
Could you attach the output of dmesg?
Comment 6 Bastien Nocera 2014-09-09 09:59:31 UTC 
(In reply to Lan Tianyu from comment #5)
> Could you attach the output of dmesg?

It's included in the journalctl output, in this attachment:
https://bugzilla.kernel.org/attachment.cgi?id=149311
Comment 7 Lan Tianyu 2014-09-10 06:59:43 UTC 
I meant the dmesg with fix patch in the bug 69011.

Please apply the following patch with enabling "CONFIG_ACPI_I2C_OPREGION".

Comment 8 Bastien Nocera 2014-11-01 23:12:22 UTC 
I applied the patch from bug 69011 comment 55, and it failed to detect the battery. Some of the errors in the dmesg say:

As far as i'm understood, the _BST method works as expected,
while the _BIX method is just a stub. This is the vendor failure
and may be fixed in the next firmware update.
There is no way to fix it in the kernel.

That's surely work-aroundable if Windows 8 can show the battery status on the same machine...
Comment 13 Pavel Bludov 2014-12-15 13:16:00 UTC 
You are right. Design_capacity is just a constant. It can be passed to the kernel via a command line parameter. Sort of

acpi.battery_design_capacity = 8500

I will try to code it.

Here is my DSDT. It ends with

	Store (And (E002, 0xFE), E002)

	Store (DECC, Index (BIXP, 0x02))

	Divide (FUEC, 0x19, Local1, Local0)
	Store (Local1, Index (BIXP, 0x07))
	Return (BIXP)
}

So, _BIX method is not a stub. But fields FG3C & FG0E are zeroes for some reason.

Any updates on the original warnings?
Comment 16 Zhang Rui 2015-02-15 08:35:01 UTC 
we have a couple of patches shipped in the latest upstream kernel, about the I2C operation region.
could you please wait and check if the problem still exists in 3.20-rc1 kernel?

No success with 4.0-rc1 on the Onda v975w.
Comment 19 Zhang Rui 2015-04-14 07:06:31 UTC 
Please rebuild your kernel with CONFIG_I2C_DESIGNWARE_PLATFORM=y, CONFIG_ACPI_AC=m, and CONFIG_ACPI_BATTERY=m, and then re-attach the dmesg output if the problem still exists.
Comment 20 Zhang Rui 2015-04-14 07:16:52 UTC 
According to Tianyu, this seems like a BIOS problem because
1. ACPI AC device accesses DVBQ operation region in I2C1 scope, but it does not have _DEP method defined.
2. ACPI battery driver accesses FSAO operation region in I2C3, but only I2C1 is referred in its _DEP method.

Thus, AC/Battery driver tries to access I2C operation region before the operation region handler is actually installed onn I2C1/I2C3.

A proper fix is
1. fix the BIOS to reflect the real dependency (_DEP)
2. make ACPI AC driver be aware of acpi_device->dep_unmet.

But anyway, to confirm this assumption, lets check if the problem can be fixed by making ACPI AC/Battery driver loaded AFTER I2C operation region handler installed, i.e. the test mentioned in comment #19..

Looks like all those were already enabled:
CONFIG_I2C_DESIGNWARE_PLATFORM=m
CONFIG_ACPI_AC=y
CONFIG_ACPI_BATTERY=y

Do they specifically need to be enabled as modules?

I'm afraid that that probably won't happen, as the vendor (Onda) has not released any new firmwares since September last year. And it probably won't as "it works with Windows"...

Ha, right, so it's important for those to be loaded as modules, not builtin. I'll launch a kernel build. Thanks.

Using v4.0-2620-gb79013b2449c
with CONFIG_I2C_DESIGNWARE_PLATFORM, CONFIG_ACPI_AC and CONFIG_ACPI_BATTERY as modules, I can't even get the machine to finish booting. I get:

Method parse/execution failed (\_SB_.GPOZ._L01) (Node ffff88005accaf50), AE_NOT_EXIST (20150204/psparse-536)

I'll test with a newer version of the kernel.

Still the same problem after making ACPI_AC and ACPI_BATTERY modules. I unloaded them both and reloaded them before checking the battery level, and still the same errors and missing battery information.
Comment 24 Bastien Nocera 2015-04-27 16:48:40 UTC 
After unloading and reloading the "battery" module, I don't get the errors above (despite what I said in comment 23).

the energy_full, energy_full_design and capacity sysfs entries both have "0" as the value, which is what causes the percentage to still show up as 0.

As it seems like an ACPI table related issue, a override could probably work:

https://01.org/linux-acpi/documentation/overriding-dsdt


I have no idea if this is correct, just a guess:

        Device (BATC)
        {
            Name (_HID, EisaId ("PNP0C0A") /* Control Method Battery */)  // _HID: Hardware ID
            Name (_UID, One)  // _UID: Unique ID
            Name (BTPC, Zero)
            Name (_DEP, Package (0x02)  // _DEP: Dependencies
            {
                I2C1,
				I2C3
            })

    Scope (_SB)
    {
        Device (ADP1)
        {
            Name (_HID, "ACPI0003" /* Power Source Device */)  // _HID: Hardware ID
            Name (_DEP, Package (0x01)  // _DEP: Dependencies

I'm getting the same 0 values and the energy_full value is got from ASL code by reading a field defined in I2C operation region. The relevant code is:

        Name (BQFG, ResourceTemplate ()
        {
            I2cSerialBus (0x0055, ControllerInitiated, 0x00061A80,
                AddressingMode7Bit, "\\_SB.I2C1",
                0x00, ResourceConsumer, ,
                )
        })
        Field (FGCP, BufferAcc, NoLock, Preserve)
        {
            Connection (BQFG),
            Offset (0x3C), 
            AccessAs (BufferAcc, AttribBytes (0x02)),
            FG3C,   8
        }
            Name (BIXP, Package (0x14)
            {

                Zero,

                0x0320,
                0x251C,
                Zero,
                Zero,
                0x64,

                "Battery ", 
                "ChipHD Battery "
            })

            Method (_BIX, 0, NotSerialized)  // _BIX: Battery Information Extended
            {
                DECC = FG3C /* \_SB_.I2C1.FG3C */
                Index (BIXP, 0x02) = DECC /* \_SB_.I2C1.BATC.DECC */
                FUEC = FG0E /* \_SB_.I2C1.FG0E */
                Index (BIXP, 0x03) = FUEC /* \_SB_.I2C1.BATC.FUEC */
                Divide (FUEC, 0x0A, Local1, Local0)
                Index (BIXP, 0x06) = Local1
                Divide (FUEC, 0x19, Local1, Local0)
                Index (BIXP, 0x07) = Local1
                Return (BIXP) /* \_SB_.I2C1.BATC.BIXP */
            }

So the information about energy_full_design: Index (BIXP, 0x02) is assigned a value of DECC, which is got from FG3C. From the debug messages, the I2C operation region handler runs well and no error occurred, only the value returned doesn't make any sense: 0.
Comment 28 Aaron Lu 2015-06-11 09:24:04 UTC 
Perhaps this is due to buggy ASL code: DECC = FG3C
DECC is not the whole buffer, the right code should be BU3C = FG3C.
Will see if it is possible to work around this in ACPICA.

The error is due to missing CONFIG_ACPI_I2C_OPREGION=y.
Just in case, you will at least need: CONFIG_GPIO_ACPI and CONFIG_GPIO_CRYSTAL_COVE too.
Comment 36 Bastien Nocera 2015-07-02 09:36:40 UTC 
They're all enabled though:

$ grep CONFIG_ACPI_I2C_OPREGION /boot/config-`uname -r`
CONFIG_ACPI_I2C_OPREGION=y
$ grep CONFIG_GPIO_ACPI /boot/config-`uname -r`
CONFIG_GPIO_ACPI=y
$ grep CONFIG_GPIO_CRYSTAL_COVE /boot/config-`uname -r`
CONFIG_GPIO_CRYSTAL_COVE=y

I didn't see any warnings related to DVBQ this time.

Too many moving parts. It seems to work with your patch, config and 4.2-rc0.

I'd like to be more helpful in my testing, but rebasing always breaks one or two components (4.2rc1 doesn't boot, for example).

Actually, it is "working" in that it reports the battery status, but that data doesn't seem to be in sync with reality.

When plugging in the AC, the battery doesn't set its status to charging, the ADP "power line" never comes online.

When installing packages which use the Wi-Fi as well as 100% CPU when decompressing to disk, the battery always report 0.064 W usage, or 57 hours until the 80% full battery is empty (I wish).

It's better but not quite there yet.
Comment 42 Aaron Lu 2015-07-15 07:31:20 UTC 
When I plug in the AC, the /sys/class/power_supply/BATC/status returns Charging.

But the power_now(which is the rate of how much power the battery is draining) indeed returns a not-seems-correct value, ranging from 7x - 8x, while the remaining capacity is 4xxx, the estimated last hour is almost 60 hours(e.g. 4762 / 80). I don't see any way to change this, the rate information is retrieved from a field in the I2C register and the operation went well, no error happened and no firmware bug is found regarding this, so no way to solve this...
Comment 43 Aaron Lu 2015-07-16 09:10:16 UTC 
I just checked Windows, it only displays how much percent the remaining battery is, no estimated remaining time. I guess that is due to Windows think the rate information is not correct so it doesn't use it. I suppose GNOME should do something similar.

An additional info. When building with CONFIG_ACPI_BATTERY=y the device doesn't boot if no USB device is hooked (at least with my kernel config).
If I put it as module or simply don't build it, it boots even without a USB device.
Comment 48 Lv Zheng 2016-05-16 22:18:12 UTC 
OK, we'll seek a way to make the fixed merged to the ACPICA upstream.
Comment 49 Lv Zheng 2016-06-22 04:54:07 UTC 
I just confirmed that currently it is not possible to work this around in ACPICA.
You need to continue to provide quirks in the I2C opregion handler.
So re-assign back to Aaron.
