2019-12-14Revert "{northbridge,soc,southbridge}: Don't use both of _ADR and _HID"Nico Huber
This reverts commit 01787608670adec26fcea48173e18395e51c790e. AMD: Dropping the _HID of PCI root bus doesn't work well and people started to notice the breakage. Intel: These platforms have a devicetree switch to choose between PCI and ACPI modes. In the former case we need _ADR, but in the latter _HID as the PCI devices are hidden. The conflicting use of _ADR and _HID still needs to be fixed before we can bump our IASL version.

2018-06-03intel bd82x6x/lynxpoint systems: Update ACPI thermal zone handlerMartin Roth
Currently the throttle event handler method THRM is defined as an extern on the intel bd82x6x and lynxpoint chipsets, then defined again in the platform with thermal event handling. In newer versions of IASL, this generates an error, as the method is defined in two places. Simply removing the extern causes the call to it to fail on platforms where it isn't actually defined, so add a preprocessor define where it's implemented, and only call the method on those platforms. This also requires moving the thermal handler, which now includes the define to before the gnvs asl file. TEST=Build before and after, make sure correct code is included.

Remove the bit of code that was putting the SerialIO devices into D3Hot state when they are switched from PCI to ACPI mode. Instead, add the appropriate ACPI Methods to allow the kernel to control the power state of the device. The problem seems to be that if the device is put in D3Hot state before it is switched from PCI to ACPI mode then it does not properly export its PCI configuration space and cannot be woken back up. Adding the ACPI Methods for _PS0/_PS3 allows the kernel to transition the device into D0 state only when it is necessary to communicate with the device, then put it back into D3Hot state.

2013-12-21lynxpoint: XHCI: Don't put device in D3 in _PS0 MethodDuncan Laurie
The end of the _PS0 method that is supposed to transition the XHCI device to D0 state is instead putting it in D3 state. This triggers a PME_B0 GPE which causes a Notify to the XHCI ACPI Device in the kernel and that increments the wakeup counter and causes aborted suspends. Instead if we just leave the device in D0 where it should be after executing this function then the PME_B0 is not generated and the kernel does not see a wakeup on XHCI. Similarly I changed the _PS3 method to always put the device in D3 at the end of the method, rather than depending on the state to be D3 at the start. Before this change the kernel would see the following sequence when trying to suspend when the XHCI controller is in D3cold: kernel: ACPI: Execute Method [\_SB_.PCI0.XHCI._PS0] (Node ffff88017802bf28) kernel: evmisc-0169 [07] ev_queue_notify_reques: Dispatching Notify on [XHCI] (Device) Value 0x02 (Device Wake) Node ffff88017802bc30 kernel: evmisc-0169 [07] ev_queue_notify_reques: Dispatching Notify on [EHCI] (Device) Value 0x02 (Device Wake) Node ffff88017802b8e8 kernel: evmisc-0169 [07] ev_queue_notify_reques: Dispatching Notify on [HDEF] (Device) Value 0x02 (Device Wake) Node ffff88017802b1b8 kernel: xhci_hcd 0000:00:14.0: power state changed by ACPI to D0 kernel: xhci_hcd 0000:00:14.0: PME# disabled kernel: xhci_hcd 0000:00:14.0: enabling bus mastering kernel: xhci_hcd 0000:00:14.0: setting latency timer to 64 kernel: PM: Wakeup pending, aborting suspend kernel: last active wakeup source: 0000:00:14.0 Now it does not get a notification (due to PME_B0) when going to D0 on the way into suspend.

2013-12-21lynxpoint: XHCI: Advertise D3 as lowest wake stateDuncan Laurie
The recommended value in docs is D2, but lynxpoint XHCI does not even support D2 state which causes the kernel to think this device cannot be used as a wake source: kernel: xhci_hcd 0000:00:14.0: System wakeup enabled by ACPI kernel: ACPI: Device does not support D2 kernel: xhci_hcd 0000:00:14.0: System wakeup disabled by ACPI Additionally this means the kernel will never put the device into D3 state by itself. There is SMI code that will put the device into D3 before suspend so advertising D3 here should be correct. With this change the kernel will put the controller into D3 on suspend and back to D0 on resume, including executing the ACPI methods for _PS0/_PS3 that contain chipset specific workarounds. In addition add a _PSC method to directly return the D state from the device registers. With ALL USB devices removed the XHCI controller goes into D3 state and the kernel can have a hard time determining the state of the device at boot.

2013-11-25lynxpoint: Change SerialIO device enable reporting to ACPIDuncan Laurie
In order to report whether coreboot enabled a SerialIO device in ACPI mode we had been relying on reading NVS in the _STA method for the SerialIO device. The ACPI _STA method has restrictions on what it can access and is unable to access OperationRegions outside its scope which means it should not be trying to read NVS. This change adds a new SSDT to the ACPI tables and fills it with constants that indicate whether or not a device is enabled in ACPI mode. The ACPI code is changed to read these variables from the SSDT and use that instead of trying to query a variable in NVS. Attempt to use lpt-clk driver to probe the device clocks for SerialIO devices and see that the kernel does not complain about accessing the GNVS region.

2013-04-01lynxpoint: Basic configuration of SerialIO devicesDuncan Laurie
This adds configuration of SerialIO devices in the Lynxpoint-LP chipset. This includes DMA, I2C, SPI, UART, and SDIO controllers. There is assorted magic setup necessary for the devices and while it is similar for each device there are subtle differences in some register settings. These devices must be put into "ACPI Mode" in order to take advantage of S0ix. When in ACPI mode the allocated PCI BARs must be passed to ACPI so it can be relayed to the OS. When the devices are in ACPI mode BAR0+BAR1 is saved into ACPI NVS and then updated and returned when the OS calls _CRS. Note that is is not entirely complete yet. We need to update the IASL compiler in our build environment to support ACPI 5.0 in order to be able to pass the FixedDMA entries to the kernel. There are also no ACPI methods defined yet to do D0->D3->D0 transitions for actually entering/exiting S0ix states. This is hard to test right now because our kernel does not support any of these devices in ACPI mode. I was able to build and test the upstream bleeding-edge branch of the linux-pm git tree. With that tree I was able to enumerate and load the driver for the DesignWare I2C driver and attempt to probe the I2C bus -- although there are no devices attatched. I am also able to see the resources from ACPI in /proc/iomem get reserved properly in the kernel.
