3.4 OEM Module Quiescence Feedback

This command is used to control a graceful shutdown of the AM4140 and is a prerequisite for

the hot swap feature. For further information on hot swap, refer to Chapter 9, Hot Swap.

A shutdown daemon compatible with the OEM Module Quiescence Feedback command

should be used to shut down the system in an orderly manner. For this purpose, Kontron’s

BSPs include a Graceful Reboot and Shutdown Daemon, “grnsd”.

This command can also be used to set a timeout time for the case that the graceful shutdown

daemon or the operating system is not responsive. The default timeout time is set to 20 sec-

onds and is stored in the MMC. Thus, the timeout is triggered even if an operating system with-

out a “grnsd” shutdown daemon is used. OSs with a graceful shutdown daemon “grnsd” can

modify the quiescent wait time as required.

REQUEST DATA

Byte Data Field

1 Control bits:

[7] - 1b = set quiesce wait timeout

[6] - 1b = quiescence acknowledge (OS ready)

[5] - 1b = OS daemon present

[4:0] Reserved

2 Quiesce wait timeout [sec]

a) An OS daemon is present (refer to bits above):

This is the maximum time from the moment on that the MMC receives FRU Control

(Quiesce) request until it sends back the appropriate Module Hot Swap event message.

b) No OS daemon is present (refer to bits above):

This is the maximum time from the moment on that the MMC receives FRU Control

(Quiesce) request until it sends back the appropriate Module Hot Swap event message. If

sleep state is recognized before timeout, the Module Hot Swap event message will be sent

immediately. If the time is set to 0 (endless wait), the Module Hot Swap event message will

only be sent after recognition of sleep state (signal).

RESPONSE DATA

Byte Data Field

1 Completion code

2 Control bits:

[7] - Reserved

[6] - 1b = quiescence acknowledge (OS ready)

[5] - 1b = OS daemon present

[4] - 1b = quiesce request (FRU Control)

[3] - Reserved

[2] - 1b = graceful reboot request (FRU Control)

[1] - 1b = quiescence reached (MMC acknowledge)

[0] - 1b = module hot swap switch opened

4 Quiesce wait timeout (valid only if OS daemon present = 1)
