HP ENVY 4 Sleekbook - Errors detected when running FWTS sleep tests

[Jeff Lane ]

Encountered several HIGH errors via fwts while running suspend and hibernate tests on the HP Envy 4 Sleekbook system.

The systems all suspended and resumed normally, these were kernel warnings that appeared in syslog. I've attached the logs to this bug, but here is the single-suspend log:

Test 1 of 1: S3 suspend/resume test.
Defaulted to 1 test, use --s3-multiple=N to run more S3 cycles
S3 cycle 1 of 1
pm-suspend returned 0 after 34 seconds.

Please run:

Some diagnosis:

1) FAILED [HIGH] KlogACPIErrorNoHandlerFor: Test 1, HIGH Kernel message: [ 3977.475196] ACPI Error: No
handler for Region [RCM0] (ffff88013bf63798) [SystemCMOS] (20120320/evregion-376)
2) FAILED [HIGH] KlogACPIErrorRegionHas: Test 1, HIGH Kernel message: [ 3977.475199] ACPI Error: Region
SystemCMOS (ID=5) has no handler (20120320/exfldio-306)

The kernel doesn't have a CMOS region handler, hence this error message, I think we can ignore these for now.

3) FAILED [HIGH] KlogACPIErrorMethodExecutionParse: Test 1, HIGH Kernel message: [ 3977.475201] ACPI
Error: Method parse/execution failed [\_SB_.WMID.ESDT] (Node ffff88013bf3dcd0), AE_NOT_EXIST
(20120320/psparse-536)

This needs examining deeper, hence the request for a dump of the ACPI tables.

4) FAILED [HIGH] KlogACPIErrorMethodExecutionParse: Test 1, HIGH Kernel message: [ 3977.475205] ACPI
Error: Method parse/execution failed [\_PTS] (Node ffff88013bf3e9d8), AE_NOT_EXIST (20120320
/psparse-536)

The _PTS (Prepare to suspend) control is called before we suspend, the kernel is grumbling that it is not implemented. Section 16.1 of the ACPI spec states:

"The _PTS control method provides the BIOS a mechanism for performing some housekeeping, such
as writing the sleep type value to the embedded controller, before entering the system sleeping state."

..so it seems that it is not necessarily manditory to have this control implemented since the BIOS does not seem to need it in this case. I will update fwts to detect this and make this into a warning rather than an error.

Some additional information to #5:

1) FAILED [HIGH] KlogACPIErrorNoHandlerFor: Test 1, HIGH Kernel message: [ 3977.475196] ACPI Error: No

2) FAILED [HIGH] KlogACPIErrorRegionHas: Test 1, HIGH Kernel message: [ 3977.475199] ACPI Error: Region

3) FAILED [HIGH] KlogACPIErrorMethodExecutionParse: Test 1, HIGH Kernel message: [ 3977.475201] ACPI

4) FAILED [HIGH] KlogACPIErrorMethodExecutionParse: Test 1, HIGH Kernel message: [ 3977.475205] ACPI
Error: Method parse/execution failed [\_PTS] (Node ffff88013bf3e9d8), AE_NOT_EXIST (20120320
/psparse-536)

The above errors are actually one error as a result of calling chain: _PTS->ESDT->RCM0, and it fails when accessing RCM0 as RTC CMOS registers aren't currently supported in Linux kernel.

Fortunately, \_SB_.WMID.ESDT is the last function in _PTS and BIOS has completed everything it tends. No or few impacts are generated by the absence of RTC CMOS handling.

[Alex Hung (alexhung)]

A patch was sent to include the CMOS handler (https://patchwork.kernel.org/patch/2052901/), but is not yet accepted.

[Alex Hung (alexhung)]

Finally upstream has a patch! This shall be included in kernel 3.11. It may be a good idea to SRU it after a while when nobody in upstream complains about it.

commit 2fa97feb4406c546b52e35b6b6c50cb8f63425d2

    ACPI: Add CMOS RTC Operation Region handler support

    On HP Folio 13-2000, the BIOS defines a CMOS RTC Operation Region and
    the EC's _REG methord accesses that region. Thus an appropriate
    address space handler must be registered for that region before the
    EC driver is loaded.

    Introduce a mechanism for adding CMOS RTC address space handlers.
    Register an ACPI scan handler for CMOS RTC devices such that, when
    a device of that kind is detected during an ACPI namespace scan, a
    common CMOS RTC operation region address space handler will be
    installed for it.

The patch will be backported to 3.9+ kernel and will be included in ubuntu 13.10

[Darren Lichty (delichty)]

I am also running into this same bug on an HP Envy 6 Sleekbook. I am currently running 12.04LTS.

When will this patch be available on 12.04LTS?

Thank you!

[Darren Lichty (delichty)]

I was mistaken, I am running 12.10.

Will this patch be back-ported to 12.10?
