linux-stable.git/drivers, branch v5.4.2 Linux kernel stable tree platform/x86: hp-wmi: Fix ACPI errors caused by passing 0 as input size 2019-12-04T21:31:08+00:00 Hans de Goede hdegoede@redhat.com 2019-11-22T18:56:41+00:00 e64cd7a033436300a1e4aee982d6530bd708f465 commit f3e4f3fc8ee9729c4b1b27a478c68b713df53c0c upstream. The AML code implementing the WMI methods creates a variable length field to hold the input data we pass like this: CreateDWordField (Arg1, 0x0C, DSZI) Local5 = DSZI /* \HWMC.DSZI */ CreateField (Arg1, 0x80, (Local5 * 0x08), DAIN) If we pass 0 as bios_args.datasize argument then (Local5 * 0x08) is 0 which results in these errors: [ 71.973305] ACPI BIOS Error (bug): Attempt to CreateField of length zero (20190816/dsopcode-133) [ 71.973332] ACPI Error: Aborting method \HWMC due to previous error (AE_AML_OPERAND_VALUE) (20190816/psparse-529) [ 71.973413] ACPI Error: Aborting method \_SB.WMID.WMAA due to previous error (AE_AML_OPERAND_VALUE) (20190816/psparse-529) And in our HPWMI_WIRELESS2_QUERY calls always failing. for read commands like HPWMI_WIRELESS2_QUERY the DSZI value is not used / checked, except for read commands where extra input is needed to specify exactly what to read. So for HPWMI_WIRELESS2_QUERY we can safely pass the size of the expected output as insize to hp_wmi_perform_query(), as we are already doing for all other HPWMI_READ commands we send. Doing so fixes these errors.

commit f3e4f3fc8ee9729c4b1b27a478c68b713df53c0c upstream.

The AML code implementing the WMI methods creates a variable length
field to hold the input data we pass like this:

        CreateDWordField (Arg1, 0x0C, DSZI)
        Local5 = DSZI /* \HWMC.DSZI */
        CreateField (Arg1, 0x80, (Local5 * 0x08), DAIN)

If we pass 0 as bios_args.datasize argument then (Local5 * 0x08)
is 0 which results in these errors:

[   71.973305] ACPI BIOS Error (bug): Attempt to CreateField of length zero (20190816/dsopcode-133)
[   71.973332] ACPI Error: Aborting method \HWMC due to previous error (AE_AML_OPERAND_VALUE) (20190816/psparse-529)
[   71.973413] ACPI Error: Aborting method \_SB.WMID.WMAA due to previous error (AE_AML_OPERAND_VALUE) (20190816/psparse-529)

And in our HPWMI_WIRELESS2_QUERY calls always failing. for read commands
like HPWMI_WIRELESS2_QUERY the DSZI value is not used / checked, except for
read commands where extra input is needed to specify exactly what to read.

So for HPWMI_WIRELESS2_QUERY we can safely pass the size of the expected
output as insize to hp_wmi_perform_query(), as we are already doing for all
other HPWMI_READ commands we send. Doing so fixes these errors.

commit 16245db1489cd9aa579506f64afeeeb13d825a93 upstream.

The HP WMI calls may take up to 128 bytes of data as input, and
the AML methods implementing the WMI calls, declare a couple of fields for
accessing input in different sizes, specifycally the HWMC method contains:

        CreateField (Arg1, 0x80, 0x0400, D128)

of this size, the APCI interpreter still tries to create it as it is
declared in generoc code at the top of the HWMC method which runs before
the code looks at which command-type is requested.

This results in many of these errors on many different HP laptop models:

commit 1cb0d2aee26335d0bccf29100c7bed00ebece851 upstream.

Upstream commit 58e75155009c ("HID: core: move Usage Page concatenation
to Main item") adds support for Usage Page item after Usage ID items
(such as keyboards manufactured by Primax).

Usage Page concatenation in Main item works well for following report
descriptor patterns:

    USAGE_PAGE (Keyboard)                   05 07
    USAGE_MINIMUM (Keyboard LeftControl)    19 E0
    USAGE_MAXIMUM (Keyboard Right GUI)      29 E7
    LOGICAL_MINIMUM (0)                     15 00
    LOGICAL_MAXIMUM (1)                     25 01
    REPORT_SIZE (1)                         75 01
    REPORT_COUNT (8)                        95 08
    INPUT (Data,Var,Abs)                    81 02

-------------

    USAGE_MINIMUM (Keyboard LeftControl)    19 E0
    USAGE_MAXIMUM (Keyboard Right GUI)      29 E7
    LOGICAL_MINIMUM (0)                     15 00
    LOGICAL_MAXIMUM (1)                     25 01
    REPORT_SIZE (1)                         75 01
    REPORT_COUNT (8)                        95 08
    USAGE_PAGE (Keyboard)                   05 07
    INPUT (Data,Var,Abs)                    81 02

But it makes the parser act wrong for the following report
descriptor pattern(such as some Gamepads):

    USAGE_PAGE (Button)                     05 09
    USAGE (Button 1)                        09 01
    USAGE (Button 2)                        09 02
    USAGE (Button 4)                        09 04
    USAGE (Button 5)                        09 05
    USAGE (Button 7)                        09 07
    USAGE (Button 8)                        09 08
    USAGE (Button 14)                       09 0E
    USAGE (Button 15)                       09 0F
    USAGE (Button 13)                       09 0D
    USAGE_PAGE (Consumer Devices)           05 0C
    USAGE (Back)                            0a 24 02
    USAGE (HomePage)                        0a 23 02
    LOGICAL_MINIMUM (0)                     15 00
    LOGICAL_MAXIMUM (1)                     25 01
    REPORT_SIZE (1)                         75 01
    REPORT_COUNT (11)                       95 0B
    INPUT (Data,Var,Abs)                    81 02

With Usage Page concatenation in Main item, parser recognizes all the
11 Usages as consumer keys, it is not the HID device's real intention.

This patch checks whether Usage Page is really defined after Usage ID
items by comparing usage page using status.

Usage Page concatenation on currently defined Usage Page will always
do in local parsing when Usage ID items encountered.

When Main item is parsing, concatenation will do again with last
defined Usage Page if this page has not been used in the previous
usages concatenation.
