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
Hello Madalin, Thank you very much for this summary that helps keeping an overview on the current Freescale mainline DPAA effort (by the way, I am also very pleased to see these patches getting to the mailing-lists, this is very important to us). Now I would like to give all this a try on our P2041 board, the kmcoge4 for which there is a DT in mainline. Could you please tell me on what kernel branch these patches are based on ? Best Regards Valentin
