2017-07-25fallback on _BIF properly when _BIX exists and returns a packageJoshua Stein
successfully but has an unexpected length, as on the X1C gen 5 tested by naddy
2017-07-22acpibat: look for _BIX first before falling back on _BIFJoshua Stein
ACPI 4.0 deprecated _BIF for battery status so some newer machines are exporting _BIX which extends _BIF's package with a few extra fields. When using _BIX, export the new discharge cycle count as a sensor. feedback from kettenis and anton ok deraadt

2017-04-08Sensors are run as callbacks inside tasks. During suspend a sensorTheo de Raadt
could be running inside a driver that will be force-detached, or due to tsleep end up disrupting the softstate/hardstate contract. At suspend time, quisce all these callbacks by waiting for completion. This issue has never been observed for real, but may be implicated in suspend/resume failures. ok kettenis guenther mlarkin

2017-03-11Revert 1.54, go back to always trying to enable burst modeJoshua Stein
Selectively enabling burst mode seems to have broken more machines than it helped. On MacBooks, EC_STAT_OBF occasionally won't show up when trying to read a byte of data when bursting hasn't been enabled, so acpiec_wait can spin forever. This again breaks on ECs that don't do burst at all, like the Chrome EC, but those are much more scarce than MacBooks at this time. A machine/bios-dependent check could be added later to disable bursting on certain machines. Discussed with deraadt
2017-03-07move a TODO to the topJoshua Stein
2017-03-02Add a new sysctl machdep.lidaction. The sysctl works as follows:Martin Natano
machdep.lidaction=0 # do nothing machdep.lidaction=1 # suspend machdep.lidaction=2 # hibernate lidsuspend is just an alias for lidaction, so if you change one, the other one will have the same value. The plan is to remove machdep.lidsuspend eventually when people have upgraded their /ets/sysctl.conf. discussed with deraadt, who came up with the new MIB name no objections mlarkin ok stsp halex jcs

2017-02-16On Apple hardware, claim an OSI of Darwin and no other OSesJoshua Stein
The DSDT on at MacBooks takes many different and beneficial code paths when the OS reports to be Darwin, but due to the way it checks OSI, we can't just add Darwin to the aml_valid_osi array since later checks for Windows variants will supersede the Darwin check. Fixes suspend and keeps Thunderbolt ports powered up after resume. One regression is that the acpibat driver no longer attaches and will require an ACPI Smart Battery driver, which is in the works. Adapted from a similar change in the Linux kernel from 2014. ok deraadt

of a OEM0 ACPI table. acpihve(4) feeds this data into the kernel entropy pool. This is less interesting for machines with rdrand, but there are still pre ivy bridge machines running Hyper-V (including parts of Azure). ok mikeb@ reyk@ deraadt@ mlarkin@
2017-01-08Make aml_rdpciaddr() work for for devices behind bridges. The code nowMark Kettenis
uses the mapping between AML nodes and PCI devices that we establish. Because _INIT methods may end up calling aml_rdpciaddr(), make sure we create that mapping early. Also handle devices that aren't actually present. These devices are now included in the mapping and reads will return an all-ones patterm whereas writes are a no-op.. ok mlarkin@

2016-10-25Deduplicate the CRS parsing code and handle broken ACPI implementations.Paul Irofti
This change was prompted by a report from Ilya Kaliman where acpiec(4) failed to initialize on his Acer Aspire S7. Further investigations showed that the machine had 4 instead of 2 resources defined inside the EC device which is a violation of all existing ACPI revisions. We now handle such machines by using the aml resource parser directly, which lead to the removal of the existing one from acpiec.c, and ignoring extra resources (although they are reported in the dmesg). In the process I also done a couple of more style(9) fixes. Suggested by and ok guenther@

2016-09-18If the APIC table (MADT) isn't present then ci_acpi_proc_id won't be setPhilip Guenther
when acpicpu tries to attach, leading to a NULL dereference. The ACPI processor object on the Dells where this was reported is bogus and useless anyway so apply the same test when deciding whether to attach to processor objects as acpicpu would when matching them to cpus.
