The <strong>VortiQa</strong> <strong>PSP</strong> uses Linux user<br />
space programming to deliver<br />
substantial benefits to software<br />
developers, including:<br />
• Ease of development<br />
• Ease of maintenance and support<br />
• Improved performance<br />
• Improved copyright protection<br />
• Better availability of software libraries<br />
<strong>VortiQa</strong> <strong>PSP</strong> Architecture<br />
The <strong>VortiQa</strong> <strong>PSP</strong> software runs on <strong>Freescale</strong>’s<br />
Linux software development kit and delivers<br />
a hardware abstraction layer to provide<br />
a consistent set of APIs across multiple<br />
<strong>Freescale</strong> QorIQ processors. The <strong>VortiQa</strong><br />
<strong>PSP</strong> also configures the hardware drivers<br />
and offers an execution context as requested<br />
by the application developer. The hardware<br />
abstraction hides hardware differences and<br />
allows programming to take place in the<br />
user space as opposed to the kernel space,<br />
thereby providing the advantage of leveraging<br />
software development investment across a<br />
range of <strong>Freescale</strong> silicon platforms.<br />
Execution Context<br />
The <strong>VortiQa</strong> <strong>PSP</strong> enables execution context<br />
similar to how the kernel provides execution<br />
contexts to networking packet processing<br />
applications. Both the hardware polling and<br />
software polling methods are supported in the<br />
packet processing within a given execution<br />
context.<br />
Hardware Drivers<br />
The <strong>VortiQa</strong> <strong>PSP</strong> provides a hardware<br />
driver layer in the Linux user space while<br />
utilizing the zero copy method in the packet<br />
processing. These drivers include support<br />
for crypto and IPSec engines SEC 3.x and<br />
SEC 4.x, <strong>Freescale</strong>’s pattern matching engine<br />
2.0, DPAA FMAN driver and QorIQ eTSEC<br />
Ethernet driver.<br />
Communication Interface<br />
The <strong>VortiQa</strong> <strong>PSP</strong> has a standard interface for<br />
communication between the <strong>PSP</strong> applications<br />
and others, such as command line interface,<br />
Web server management or any other<br />
daemon running as part of the overall system.<br />
It is possible to utilize multiple simultaneous<br />
communication channels.<br />
Networking Service<br />
The <strong>VortiQa</strong> <strong>PSP</strong> provides a network interface<br />
manager, ARP data base facilities and<br />
maintains routing tables and bridging facilities.<br />
Session and Flow Manager<br />
The <strong>VortiQa</strong> <strong>PSP</strong> provides session and flow<br />
manager services which track the sessions<br />
and provide NAT functions. Applications<br />
requiring L4 session tracking can take<br />
advantage of this service.<br />
Generic Utility Library<br />
The <strong>VortiQa</strong> <strong>PSP</strong> provides several<br />
programming utilities, including timer libraries,<br />
memory pool manager, packet buffer<br />
manager, locks, multicore hash table and<br />
statistics-gathering support.<br />
Key Features<br />
• Multicore layer abstraction to allow core<br />
to core application scalability by hiding<br />
the number of cores and intelligently<br />
mapping the application flows to<br />
execution threads<br />
• Provides a consistent interface across<br />
the QorIQ product families to fill hardware<br />
gaps and hide hardware differences<br />
• Hardware driver support in Linux user<br />
space: Ethernet, SEC and PME engines<br />
• Full DPAA offload for applications<br />
running in Linux user space. <strong>VortiQa</strong> <strong>PSP</strong><br />
leverages hardware acceleration facilities,<br />
such as checksum verification/generation<br />
and packet distribution.<br />

• Provides network services such as<br />
interface database, routing database,<br />
ARP database, bridging and forwarding<br />
• Data plane route module is synchronized<br />
with control plane routing table, allowing<br />
route lookups required for the packet<br />
traversals<br />
• Provides stateful session management<br />
in the data plane, including creating,<br />
deleting sessions and optimizing a lockfree<br />
session table lookup<br />
• Provides communication mechanisms<br />
between control plane and data plane for<br />
packets and inter-module messaging for<br />
short and bulk messages<br />
• Provides support for IPv4 and IPv6<br />
protocols<br />
• Statistics support<br />
• Memory management<br />
• Provides a large number of well-defined<br />
timer APIs consisting of a mix of<br />
hardware with minimum software that<br />
leverage the queue manager and DPAA<br />
buffer manager<br />
