# Sleep
# -----
#
# The system will not resume from sleep properly while on battery power in
# either offload mode or sync mode. When it tries to resume, it gets to a
# state with a cursor in the top left hand side of the panel, the power LED
# goes from flashing to solid, and thereafter cannot be interacted with (even
# over SSH) and must be power cycled forcefully. Sometimes it doesn't even
# finish going to sleep before this behavior kicks in.
#
# When on AC, the machine either wakes up from sleep before being asked to
# (or maybe never gets to sleep state), or it goes into a sleep state and it
# appears consistently resume properly when it does.
#
# But the machine actually sleeps and resumes reliably when tlp is disabled
# fully or partially. Disabling RUNTIME_PM and AHCI_RUNTIME_PM appears to be
# enough to allow it to work when tlp is active. I couldn't figure out a
# more granular way to get it working, despite trying to do a per-device
# binary search via powertop.
#
# My personal configuration to make this work looks like this:
#
# {config, lib, ...}:
#
# {
# services.tlp = {
# settings = {
# # DISK_DEVICES must be specified for AHCI_RUNTIME_PM settings to work right.
# DISK_DEVICES = "nvme0n1 nvme1n1 sda sdb";
#
# # with AHCI_RUNTIME_PM_ON_AC/BAT set to defaults in battery mode, P51
# # can't resume from sleep and P50 can't go to sleep.
# AHCI_RUNTIME_PM_ON_AC = "on";
# AHCI_RUNTIME_PM_ON_BAT = "on";
#
# # with RUNTIME_PM_ON_BAT/AC set to defaults, P50/P51 can't go to sleep
# RUNTIME_PM_ON_AC = "on";
# RUNTIME_PM_ON_BAT = "on";
# };
# };
# }
#
# I'm thinking this is too aggressive to put into shared config, and folks may
# be concerned with the hit on battery life.
# See sleep.nix inside this directory for code that allows the system to
# sleep properly (out of the box, it will not) at the cost of battery life.
#
# throttled vs. thermald
