Limit the number of queued writes per client. Writes above this threshold are blocked till place in the transmit queue is available. The limit is configurable via sysfs and defaults to 50. The implementation should provide blocking I/O behavior. Prior to this change one would end up in the hands of OOM.

Description: Display fw status registers content
|
|
|
|
The ME FW writes its status information into fw status
|
|
registers for BIOS and OS to monitor fw health.
|
|
|
|
The register contains running state, power management
|
|
state, error codes, and others. The way the registers
|
|
are decoded depends on PCH or SoC generation.
|
|
Also number of registers varies between 1 and 6
|
|
depending on generation.
