2017-01-14Revert aml_rdpciaddr changes; breaks several machines that were workingMark Kettenis
before.

able to fit "Hyper_V_Gen_Counter_V1". ok mlarkin@ deraadt@
2017-01-10Hyper-V hosts make 64 bytes of entropy available to guests in the formJonathan Gray
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@
2016-10-25Add the resource index to aml_parse_resource() callback function.Paul Irofti
This is needed by an upcoming acpiec commit that handles machines breaking the current ACPI specifications. Change suggested by and ok kettenis@, guenther@

telling the audio subsystem about this later on in boot. (Mute state is maintained by the BIOS over a suspend, hibernate, reboot, etc -- this may be last missing piece of the puzzle we tore our hair out in Brisbane) diagnosis and code by Anton Lindqvist, ok ratchov

these occurring recently.
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. Problem reported by Eivind Eide (xenofil (at) gmail.com) and Johan Huldtgren (johan+openbsd-bugs (at) huldtgren.com). Testing by Eivind Eide. ok kettenis@ mlarkin@

This fixes the problem that long-running machines which were not shut down properly would reboot with a badly offset system time. hints and ok kettenis@
2016-09-02Remove unused argument in aml_showvalue().Paul Irofti
The second argument of aml_showvalue() was probably supposed to set the verbosity level through dnprintf() but in fact it does nothing. OK deraadt@

2016-08-31Don't put a device in the wake device list if _STA says it's not there.Mike Larkin
Fixes at least one machine that woke up from sleep / poweroff immediately. ok kettenis@, tested by kettenis and martijn@
2016-08-23don't enter burst mode for single-byte reads and writes.Joshua Stein
avoids problems on hardware with broken or unimplemented burst mode and isn't really necessary for such small transactions anyway. matches what linux and freebsd have done for a long time. tested in snaps ok deraadt kettenis

2016-07-10Pay attention to Processor Local X2APIC structures. ACPI 6.0 allows theseMark Kettenis

2016-05-08Add support for level, active low gpio interrupts.Mark Kettenis
2016-05-08Add support for writing gpio pins.Mark Kettenis
2016-05-08Make sure devices listed by a device's _DEP method are attached beforeMark Kettenis
we attach the device itself. The _DEP methode, introduced in ACPI 5.0, is a hint that the device in question depends on OpRegion support from the devices listed by _DEP, so we have to order them the proper way. To prevent us from attaching those devices again when we encounter them later walking down the device tree, keep track of our attempts to attach a device driver to them using aflag in the aml_node structure. ok guenther@

2016-05-08Plug some memory leaks and do proper cleanup in error paths.Mark Kettenis

2016-05-07Add chvgpio(4), a driver for the GPIO controllers found on Intel's Cherry ViewMark Kettenis
SoC.
2016-05-07Implement ACPI 5.0 GeneralPurposeIo OpRegion support. This basically allowsMark Kettenis
AML to peek and poke at GPIO pins as if it were reading and writing registers. For now this only implements peeking at pins. It will print a message if AML attempt to poke at a pin. And it will panic if the assumptions made in the code are violated. ok mlarkin@
2016-05-07Add defines for Operation Region Address Space Identifiers and use them whenMark Kettenis
acpiec(4) calls the _REG method. ok mlarkin@
2016-05-05Return ENOTTY in acpithinkpad backlight get/set ioctls if the maximumJonathan Gray
value is 0 to match the behaviour when the callbacks are not set. Prevents a divide by zero in wsconsctl(8) reported by Caspar Schutijser. earlier version ok jung@ deraadt@ kettenis@
2016-05-04Don't mask pins configured as direct IRQ. Those are tied directly to the APICMark Kettenis
and don't generate a GPIO controller interrupt. Masking them menas devices relying on those APIC interrupts will break. Unbreaks the keyboard on the Asus x205ta, which got broken in rev 1.6.
2016-05-03Print missing newline if we bail out because of a uid mismatch.Mark Kettenis
2016-04-30Mask all gpio interrupts when we attach. Fixes interrupt storm on the LenovoMark Kettenis
Ideacentre Stick 300.
2016-04-30Implement DMA support. Bits and pieces taken from NetBSD, but we onlyMark Kettenis
support ADMA2. The older SDMA mode has too many limitations to be really usable. Gives us only moderate speed improvements, bus reduces the CPU load considerably. We will reap the full benefits once we implement wider bus widths and high speed modes. There is a remining issue with simultanious use of eMMC and external SD card on (some) Intel Bay Trail hardware. Still under investigation. ok patrick@, stsp@, deraadt@
2016-04-26Remove debug printfs, but do print "gpio" to indicate that card detection isMark Kettenis
done through a gpio pin instead of the standard register.
