Hello Patrick Rudolph, Karthik Ramasubramanian, Rajat Jain, Tim Wawrzynczak, Shelley Chen, build bot (Jenkins), Furquan Shaikh,
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/34289
to look at the new patch set (#3).
Change subject: soc/intel/cannonlake: Split the "internal PME" wake-up into more detail ......................................................................
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
