Paul Fagerburg 877481cda2 soc/intel/cannonlake: Split the "internal PME" wake-up into more detail
The "internal PME" wake-up source could be from integrated LAN,
HD audio/audio DSP, SATA, XHCI, CNVi, or an ME maskable host wake.
chromium:1680839 adds USB port details to the wake-up when the
XHCI causes the wake-up. Expand the logging for wake-up details to
identify and log the other wake-up sources with more details. Note that
wake on Integrated LAN (GbE), SATA, and ME Maskable Host Wake are not
in use on Hatch, so these will not be tested.

BUG=b:128936450
BRANCH=none
TEST=``FW_NAME=hatch emerge-hatch chromeos-ec depthcharge vboot_reference
libpayload coreboot-private-files intel-cmlfsp coreboot-private-files-hatch
coreboot chromeos-bootimage``
Ensure /build/hatch/firmware/image-hatch.serial.bin has been built.
Program image-hatch.serial.bin into the DUT using flashrom.
Switch the DUT to the console (Ctrl-Alt-F2, or use the AP console via
servo).

XHCI USB 2.0
* Plug a USB keyboard into a USB-A port
* ``powerd_dbus_suspend``
* Verify low power mode by issuing the ``powerinfo`` command on the EC
console (via servo). Expect to see ``power state 4 = S0ix``.
* Press a key on the USB keyboard
* ``mosys eventlog list`` shows:
12 | 2019-06-26 14:52:23 | S0ix Enter
13 | 2019-06-26 14:53:07 | S0ix Exit
14 | 2019-06-26 14:53:07 | Wake Source | PME - XHCI (USB 2.0 port) | 3
15 | 2019-06-26 14:53:07 | Wake Source | GPE # | 109

CNVi (connected to Wi-Fi):
* Enable wake on disconnect via ``iw phy0 wowlan enable disconnect``
* Set up a hotspot on an Android phone
* Connect the Chromebook to th hotspot
* ``powerd_dbus_suspend``
* Verify low power mode by issuing the ``powerinfo`` command on the EC
console (via servo). Expect to see ``power state 4 = S0ix``.
* Turn off the hotspot on the phone
* ``mosys eventlog list`` shows:
8 | 2019-07-11 10:58:17 | S0ix Enter
9 | 2019-07-11 10:59:17 | S0ix Exit
10 | 2019-07-11 10:59:17 | Wake Source | PME - WIFI | 0
11 | 2019-07-11 10:59:17 | Wake Source | GPE # | 109

XHCI USB 3.0
* TBD

HD Audio
* TBD

coreboot README

coreboot is a Free Software project aimed at replacing the proprietary BIOS (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a payload.

With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like PC BIOS services or UEFI. This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required.

coreboot was formerly known as LinuxBIOS.

Payloads

After the basic initialization of the hardware has been performed, any desired "payload" can be started by coreboot.

See https://www.coreboot.org/Payloads for a list of supported payloads.

Supported Hardware

coreboot supports a wide range of chipsets, devices, and mainboards.

For details please consult:

Build Requirements

  • make
  • gcc / g++ Because Linux distribution compilers tend to use lots of patches. coreboot does lots of "unusual" things in its build system, some of which break due to those patches, sometimes by gcc aborting, sometimes - and that's worse - by generating broken object code. Two options: use our toolchain (eg. make crosstools-i386) or enable the ANY_TOOLCHAIN Kconfig option if you're feeling lucky (no support in this case).
  • iasl (for targets with ACPI support)
  • pkg-config
  • libssl-dev (openssl)

Optional:

  • doxygen (for generating/viewing documentation)
  • gdb (for better debugging facilities on some targets)
  • ncurses (for make menuconfig and make nconfig)
  • flex and bison (for regenerating parsers)

Building coreboot

Please consult https://www.coreboot.org/Build_HOWTO for details.

Testing coreboot Without Modifying Your Hardware

If you want to test coreboot without any risks before you really decide to use it on your hardware, you can use the QEMU system emulator to run coreboot virtually in QEMU.

Please see https://www.coreboot.org/QEMU for details.

Website and Mailing List

Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website:
