Hello,
while testing kernel-5.1 I get on one of my Lenovo Laptops very
strange 'ACPI Debug:' messages.
After some grepping I realized these are Debug messages from DSDT ,
however my kernel does
not have ACPI_DEBUG enabled.
I found out the module triggering this, on this Laptop is
ideapad_laptop , but looking at the code
I cannot see what would causes that.
Also on the same Laptop with any 5.0.X kernels I cannot see these.
~$ grep -i ACPI_DEBUG /boot/config-5.1-fw1
# CONFIG_ACPI_DEBUGGER is not set
# CONFIG_ACPI_DEBUG is not set
# CONFIG_THINKPAD_ACPI_DEBUGFACILITIES is not set
# CONFIG_THINKPAD_ACPI_DEBUG is not set
.. dmesg ..

These =====QUERY_XX===== messages are from DSDT:
~/acpi$ grep QUERY dsdt.dsl
Debug = "=====QUERY_11====="
Debug = "=====QUERY_12====="
Debug = "=====QUERY_24====="
Debug = "=====QUERY_25====="
Debug = "=====QUERY_37====="
Debug = "=====QUERY_38====="
Debug = "=====QUERY_64====="
Debug = "=====QUERY_65====="
Also this is the code from DSDT for QUERY 64 and 65:
...
Method (_Q64, 0, NotSerialized) // _Qxx: EC Query
{
Debug = "=====QUERY_64====="
If ((OSYS == 0x07D9))
{
If (((WLEX == One) & (WLAT == One)))
{
SGOV (0x02040005, One)
}
Else
{
SGOV (0x02040005, Zero)
}
}
}
Method (_Q65, 0, NotSerialized) // _Qxx: EC Query
{
Debug = "=====QUERY_65====="
If ((OSYS == 0x07D9))
{
If (((BTEX == One) & (BTAT == One)))
{
SGOV (0x0202000B, One)
}
Else
{
SGOV (0x0202000B, Zero)
}
}
}
...
Any idea what would cause this ?
BR,
Gabriel C
