Hi all,
I have a question about the power manager settings under Windows CE 6.00
On my BSP, I have 2 serial ports. I have added power management support
on the serial port driver.
In the registry, I have put following settings:
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\COM1]
"DeviceArrayIndex"=dword:0
"IoBase"=dword:1000C000 ;UART3 Memory Map Address
"IoLen"=dword:D4
"Prefix"="COM"
"Dll"="mx27_serial.Dll"
"Order"=dword:1
"Priority"=dword:0
"Index"=dword:1

"IClass"=multi_sz:"{CC5195AC-BA49-48a0-BE17-DF6D1B0173DD}","{A32942B7-920C-486b-B0E6-92A702A99B35}"

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\COM2]
"DeviceArrayIndex"=dword:0
"IoBase"=dword:1000A000 ;UART1 Memory Map Address
"IoLen"=dword:D4
"Prefix"="COM"
"Dll"="mx27_serial.Dll"
"Order"=dword:1
"Priority"=dword:0
"Index"=dword:2

"IClass"=multi_sz:"{CC5195AC-BA49-48a0-BE17-DF6D1B0173DD}","{A32942B7-920C-486b-B0E6-92A702A99B35}"


My goal is to be able to cut-off all serial ports in a specific system
power state called "LocalMode". To do this I added following settings in
the registry.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\State\LocalMode\{CC5195AC-BA49-48a0-BE17-DF6D1B0173DD}]
"Default"=dword:4; D4
"Flags"=dword:0

But this don't work!

When I dot this
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\State\LocalMode]
"Default"=dword:0; D0
"com1:"=dword:4;
"com2:"=dword:4;
"Flags"=dword:0


The serial ports are down...
So I have a working solution for my application, but can someone explain
me why the first solution don't work?

Best regards

Fabrice

AS UP TO MY KNOWLEDGE
"{CC5195AC-BA49-48a0-BE17-DF6D1B0173DD}" is the class guid for serial port
driver(CE_DRIVER_SERIAL_PORT_GUID). and this is not the power class guid. See
the following registry...

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\Interfaces]
"{A32942B7-920C-486b-B0E6-92A702A99B35}"="Generic power-manageable
devices"
"{8DD679CE-8AB4-43c8-A14A-EA4963FAA715}"="Power-manageable block devices"
; @CESYSGEN IF CE_MODULES_NDIS
"{98C5250D-C29A-4985-AE5F-AFE5367E5006}"="Power-manageable NDIS miniports"
; @CESYSGEN ENDIF CE_MODULES_NDIS
; @CESYSGEN IF CE_MODULES_GWES
"{EB91C7C9-8BF6-4a2d-9AB8-69724EED97D1}"="Power-manageable display"

These are the class guids used for different classifications of devices.
serial driver power classification will come under the
"{A32942B7-920C-486b-B0E6-92A702A99B35}"="Generic power-manageable devices"
power class.
Instead of this,

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\State\LocalMode\{CC5195AC-BA49-48a0-BE17-DF6D1B0173DD}]
"Default"=dword:4; D4
"Flags"=dword:0

you can try this . but it will affect other drivers registered in the same
power class.


[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\State\LocalMode\{A32942B7-920C-486b-B0E6-92A702A99B35}]
"Default"=dword:4; D4
"Flags"=dword:0

So if you what to control your serial drivers alone, the best way is the
second one.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\State\LocalMode]
"Default"=dword:0; D0
"com1:"=dword:4;
"com2:"=dword:4;
"Flags"=dword:0

I have more more idea, but i didn't experiment before.you can try with your
own risk.
can you add the "{CC5195AC-BA49-48a0-BE17-DF6D1B0173DD}" to the
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\Interfaces]
list and try the same one you have done initially.
it may work out. (BUT NOT SURE).

Good Luck,

Hi Vinoth
I think you are right.
The {CC5195AC-BA49-48a0-BE17-DF6D1B0173DD} class guid is for serial=20
port, and has no link to power manager.
Your explanation seems to be logical for me, in my mind I have link all=20
GUID with the Power-manager, but that's not the case.
Now I understand why it doesn't work :-)

Thanks a lot for your comments

Fabrice

Make sure your settings are in the boot hive!
