Description
|
There are some cards which use Relaxed Ordering with Bypass Mode on
OPL Platform. However, the Relaxed Ordering cannot work because the
control bits are not set which enable the relaxed ordering.
Card will use Relaxed Ordering with Bypass Mode. Otherwise, the
performance of that will be getting worse without Relaxed Ordering.
- Configuration -
H/W : SUNW,SPARC-Enterprise
+ PCI-Express Card which requires Relaxed Ordering with Bypass Mode.
S/W : Solaris 10 11/06 or later
- Request for Enhancement -
As the above description, Relaxed Ordering Specify Bit Enable is not
set. Also there are no any I/Fs to control that bits from device
drivers. That means Relaxed Ordering cannot be used.
So, we think the following implementations are needed.
1. Implement I/F to control the bits of Relaxed Ordering Specify
Bit Enable.
2. Implement the I/F as the device driver can control because of
the bit configuration.
On the another hand, about the Bypass Mode, it's already set to
enable it during the initialization. There are no issue for this.
About the bit maps of Relaxed Ordering control and Bypass Mode Enabled,
please look at the comment section.
