* [PATCH 00/12] Freescale DPAA FMan @ 2015-06-10 15:21 Madalin Bucur 2015-06-10 15:21 ` [PATCH 07/12] fsl/fman: Add FMan MURAM support Madalin Bucur 0 siblings, 1 reply; 2+ messages in thread From: Madalin Bucur @ 2015-06-10 15:21 UTC (permalink / raw) To: netdev, linux-kernel, linuxppc-dev; +Cc: scottwood, Madalin Bucur The Freescale Data Path Acceleration Architecture (DPAA) is a set of hardware components on specific QorIQ multicore processors. This architecture provides the infrastructure to support simplified sharing of networking interfaces and accelerators by multiple CPU cores and the accelerators. One of the DPAA accelerators is the Frame Manager (FMan) which contains a series of hardware blocks: ports, Ethernet MACs, a multi user RAM (MURAM) and Storage Profile (SP). This patch set introduced the FMan driver code that configures and initializes the FMan hardware blocks, offering support for three different types of MACs (DTSEC, TGEC, MEMAC). The first 6 patches present the FMan Foundation Libraries (FLIBs). The FMan drivers make use of the basic API the FMan FLib provides to configure and control the FMan hardware. The remaining patches present the required FMan hardware module drivers. The driver structure and a hint on file naming: -------------------------------- | FMan MAC driver | mac* files ------ ------ ----- ------- ---- | FMan | Port | MAC | MURAM | SP | fm_* files ------ ------ ----- ------- ---- : : FLib : : fman_* files ------------------- This submission is based on the prior Freescale DPAA FMan V3,RFC submission. Several issues addresses in this submission: - Reduced MAC layering and complexity - Reduced code base - T1024/T2080 10G best effort support Igal Liberman (12): fsl/fman: Add the FMan FLIB headers
