HI there.
As you maybe know, I've evaluated RSS feature of Intel 82598EB AF 10G
Interface.
and I got satisfactory result. (I'd like to thanks some of you helped me.)
At this time, I have to another important feature of the Intel NIC. That
is DCA(Direct Cache Access).
But, It request supporting of BIOS's DCA enabling.
and I found some conversations about it like this conversation
http://kerneltrap.org/mailarchive/linux-netdev/2009/1/26/4819134
However, according to this conversation, To enable DCA, support of BIOS
is mandatory and there is no way only by software.
In this situation, I checked my testing system that is consist of Intel
Server Board S5000PSL mainboard.
Even though chipset of the mainboard is supporting the DCA feature,
BIOS doesn't have DCA enable configuration.
(I can't understand that. It is a product of Intel and named "server
board", Isn't it?)
There is a option that is enabling only Intel I/OAT and it's not that I
want.
FYI, It is need to introduce briefly.
CPU : Two of Quad-core Intel Xeion Processor E5430.
RAM : ECC fully Buffered DDR2
NIC : Intel 10Gigabit XF SR(EXPX9501AFXSR) Single Port (82598EB) and
Intel PRO/1000 PT quad port(EXPI9404PT) copport (82591)
M/B : ntel Server Board S5000PSL
So, What I want to know is the name of product or model number that have
BIOS supporting DCA.
If there are anybody who know about it, please let me know.
Thank you for your help in advance.
Best Regards.
P.S. Whenever I post a question, I'm afraid of my "poor" English :-(
