title: Qualcomm Technologies, Inc. ADSP Sleep Monitor
|
||||
|
||||
description:
|
||||
The ADSP Sleep monitor driver tracks ADSP sleep statistics stored in SMEM region
|
||||
and establishes an interface with different userspace clients which make use of
|
||||
ADSP subsystem. Based on the activity notifications from the userspace clients
|
||||
for activity start and stop notifications, the driver detects and logs an error
|
||||
message in kernel logs and creates a kernel/ADSP panic (when enabled) upon detecting
|
||||
a violation in ADSP sleep/LPI state after the configured monitoring duration.
|
||||
By default the driver emits out kernel message on detecting these violations,
|
||||
optionally a kernel/ADSP panic can be enabled separately for ADSP sleep or LPI
|
||||
issues via this config. When enabled, corresponding panics can be
|
||||
disabled/re-enabled runtime via debugfs node exposed from the driver.
|
||||
|
||||
"echo 0 > /d/adspsleepmon/panic-state"

|
||||

|

ADSP sleep monitor doesn't track non-audio activities on ADSP.
|
||||
The panic can result in false positives if ADSP is kept active for
|
||||
the specified duration by a non-audio entity
|
||||
(sensors, camera, charger, wifi paging etc.). When enabling, the
|
||||
minimum duration and number of CPU resumes should be fine tuned based
|
||||
on the expected non-audio use case scenarios on ADSP.
