Message-ID: <1427905165-27732-1-git-send-email-madalin.bucur@freescale.com> Date: Wed, 1 Apr 2015 19:19:25 +0300 From: Madalin Bucur <madalin.bucur@...escale.com> To: <netdev@...r.kernel.org>, <linuxppc-dev@...ts.ozlabs.org> CC: <linux-kernel@...r.kernel.org>, Madalin Bucur <madalin.bucur@...escale.com> Subject: [PATCH RFC 00/10] introduce DPAA Ethernet driver This is the second version of a patch series that adds the Ethernet driver for the Freescale QorIQ Data Path Acceleration Architecture (DPAA). This second version includes the changes requested by Kumar Gala. The PM ops patch was removed as the supporting FMan driver code was de-featured from the first submission of the driver to reduce the review effort. Together with the driver a managed version of alloc_percpu is provided that simplifies the release of percpu memory. The Freescale DPAA architecture consists in a series of hardware blocks that support the Ethernet connectivity. the Ethernet driver depends upon the Peripheral Access Memory Unit (PAMU), Frame Manager (FMan), Queue Manager (QMan), Buffer Manager (BMan). Drivers for these blocks are currently in the kernel or in review. The current set of RFC patches is meant to provide early access to the codebase and also provide context and aid the review of the latest FMan driver patches submitted by Igal Liberman: [RFC,v2,12/12] soc/fman: Add FMan MAC driver [RFC,v2,11/12] soc/fman: Add FMan Port Support [RFC,v2,10/12] soc/fman: Add FMan SP support [RFC,v2,09/12] soc/fman: Add FMan MAC support [RFC,v2,08/12] soc/fman: Add Frame Manager support [RFC,v2,07/12] soc/fman: Add FMan MURAM support [RFC,v2,06/12] soc/fman: Add the FMan MAC FLIB [RFC,v2,05/12] soc/fman: Add the FMan MAC FLIB headers [RFC,v2,04/12] soc/fman: Add the FMan port FLIB [RFC,v2,03/12] soc/fman: Add the FMan port FLIB headers [RFC,v2,02/12] soc/fman: Add the FMan FLIB [RFC,v2,01/12] soc/fman: Add the FMan FLIB headers https://patchwork.ozlabs.org/project/linuxppc-dev/list/?submitter=Igal.Liberman&state=*&q=RFC%2Cv2 These patches rely also on the Q/BMan drivers submitted by Emil Medve: [RFC,v3,10/10] fsl_qman: Add HOTPLUG_CPU support [RFC,v3,09/10] fsl_bman: Add HOTPLUG_CPU support [RFC,v3,08/10] fsl_qman: Add debugfs support [RFC,v3,07/10] fsl_bman: Add debugfs support [RFC,v3,06/10] fsl_qman: Add self-tester [RFC,v3,05/10] fsl_bman: Add self-tester [RFC,v3,04/10] powerpc/mpc85xx: Add platform support for the Freescale DPAA QMan [RFC,v3,03/10] powerpc/mpc85xx: Add platform support for the Freescale DPAA BMan [RFC,v3,02/10] fsl_qman: Add drivers for the Freescale DPAA QMan [RFC,v3,01/10] fsl_bman: Add drivers for the Freescale DPAA BMan https://patchwork.ozlabs.org/project/linuxppc-dev/list/?submitter=Emil+Medve&state=*&q=RFC The DPAA Ethernet driver is the result of the collaborative work of many individuals, to name a few: Andy Fleming Emil Medve Kumar Gala Ioana Radulescu Bogdan Hamciuc Madalin Bucur Cristian Sovaiala Marian Rotariu Andrei Pistirica Cristian Bercaru The current patch set is the result of a sustained clean-up and adaptation work on the QorIQ DPAA drivers released in the open source Freescale SDK. The SDK drivers differ as they offer support for advanced accelerations and other features that are not upstreamable. The SDK Ethernet driver is based on a different, non-upstreamable variant of the FMan driver. The short term goal is to provide basic Ethernet support in the vanilla kernel then to gradually increase the feature set. The SDK documentation and source code, documentation for the DPAA hardware are available from the company website.
