Dear FreeBSD ACPI Community,
I am trying to implement WakeOnUSB (e.g. USB keyboard input) from S3 Sleep
state, but have no clue where to start from.
I noticed the PS2 keyboard is capable of waking up a system and also found
there is a PS2 handler portion in asl from acpidump:
Method (PS2K._PRW, 0, NotSerialized) // _PRW: Power Resources
for Wake
{
Return (GPRW (0x6B, 0x03))
}
However, there is no such handle for individual usb ports other than its
parent's class (\_SB_.PCI0.XHC_).
Also, I found there are FreeBSD-specific ACPICA C codes under /sys/dev
including acpi_button.c and acpi_lid.c, which are only for the fixed acpi
components.
So my question is,
Is it possible to implement WakeOnUSB input for individual USB ports by
somehow fixing the ACPICA C codes (without fixing the asl as it is
system-dependent)? If so, how?
I would really appreciate it if you could help me out here.
Best regards,
Julian
Hi,
The USB controller drivers shutdown the HC at suspend and reset at
resume. That has proven to work the best. At the moment I think wakeup
by USB resume is not supported.
