From 8df017d70c54ceafc99b7904785603c678a2e5c1 Mon Sep 17 00:00:00 2001 From: Razvan Stefanescu Date: Tue, 22 Sep 2015 11:36:34 +0300 Subject: [PATCH 220/226] dpaa2-ethsw: Ethernet Switch driver This is a commit of the cummulative, squashed dpaa2-l2switch patches. All the commit logs are preserved below. Signed-off-by: Stuart Yoder --------------------------------------------------------------------- dpaa2-ethsw: Ethernet Switch driver Initial support for DPAA2 L2 switch. The switch and all ports are presented as network interfaces in linux (swX and swXpY). I/O functionality is not available on these interfaces, they are exclusively for management. Configuration is done using bridge tool. Supported commands are: - fdb operations with unicast/multicast addresses - vlan configuration - setting STP state of ports - flooding, learning control Offers support for retrieving port statistics via ethtool (or similar applications). This patch contains the following patches squashed together: staging: fsl-dpaa2: ethsw: ethernet switch driver dpaa2-ethsw: Include by default in configuration staging: fsl-dpaa2: ethsw: Rebasing onto kernel 4.0 staging: fsl-mc: migrated remaining flibs for MC fw 8.0.0 dpaa2-ethsw: Prefix driver name with dpaa2- dpaa2-ethsw: Set carrier state on probe dpaa2-ethsw: Add support for link state update These patches were initally submitted by: Alex Marginean J. German Rivera Razvan Stefanescu and reviewed by Stuart Yoder Ported to linux-v4.1 by updating iflink usage and ndo_bridge_getlink() parameters list update. Signed-off-by: Razvan Stefanescu [Stuart: resolved minor merge conflicts] Signed-off-by: Stuart Yoder dpaa2-ethsw: Update dpsw binary interface to 7.0 This corresponds to MC release 0.8.0. Signed-off-by: Razvan Stefanescu dpaa2-ethsw: Add object version check Abort probing if DPSW object version is smaller than required. Signed-off-by: Razvan Stefanescu dpaa2-ethsw: Fix interrupt handling Mask only the events handled by the driver - DPSW_IRQ_EVENT_LINK_CHANGED. Use clear-on-read mechanism for the interrupt status and avoid calling dpsw_clear_irq_status(). Status contains the events handled (only link state change for the moment) and masks the first 16-bits, as they are used to store the interface ID that generated the event. Signed-off-by: Razvan Stefanescu dpaa2-ethsw: resolve compile issues on uprev to 4.5 -irq_number field no longer exists in fsl-mc interrupt struct -netdev_master_upper_dev_link() has 2 new parameters, which are set to NULL for now Signed-off-by: Stuart Yoder --- MAINTAINERS | 6 + drivers/staging/fsl-dpaa2/Kconfig | 1 + drivers/staging/fsl-dpaa2/Makefile | 1 + drivers/staging/fsl-dpaa2/ethsw/Kconfig | 7 + drivers/staging/fsl-dpaa2/ethsw/Makefile | 10 + drivers/staging/fsl-dpaa2/ethsw/dpsw-cmd.h | 916 ++++++++++++ drivers/staging/fsl-dpaa2/ethsw/dpsw.c | 1639 +++++++++++++++++++++ drivers/staging/fsl-dpaa2/ethsw/dpsw.h | 2164 ++++++++++++++++++++++++++++ drivers/staging/fsl-dpaa2/ethsw/switch.c | 1711 ++++++++++++++++++++++ drivers/staging/fsl-mc/include/net.h | 1 - 10 files changed, 6455 insertions(+), 1 deletion(-) create mode 100644 drivers/staging/fsl-dpaa2/ethsw/Kconfig create mode 100644 drivers/staging/fsl-dpaa2/ethsw/Makefile create mode 100644 drivers/staging/fsl-dpaa2/ethsw/dpsw-cmd.h create mode 100644 drivers/staging/fsl-dpaa2/ethsw/dpsw.c create mode 100644 drivers/staging/fsl-dpaa2/ethsw/dpsw.h create mode 100644 drivers/staging/fsl-dpaa2/ethsw/switch.c --- a/MAINTAINERS +++ b/MAINTAINERS @@ -4554,6 +4554,12 @@ S: Maintained F: drivers/staging/fsl-mc/bus/mc-ioctl.h F: drivers/staging/fsl-mc/bus/mc-restool.c +FREESCALE DPAA2 ETHERNET SWITCH DRIVER +M: Alex Marginean +L: linux-kernel@vger.kernel.org +S: Maintained +F: drivers/staging/fsl-dpaa2/ethsw/ + FREESCALE DPAA2 MAC/PHY INTERFACE DRIVER M: Alex Marginean L: linux-kernel@vger.kernel.org --- a/drivers/staging/fsl-dpaa2/Kconfig +++ b/drivers/staging/fsl-dpaa2/Kconfig @@ -11,3 +11,4 @@ config FSL_DPAA2 source "drivers/staging/fsl-dpaa2/ethernet/Kconfig" source "drivers/staging/fsl-dpaa2/mac/Kconfig" source "drivers/staging/fsl-dpaa2/evb/Kconfig" +source "drivers/staging/fsl-dpaa2/ethsw/Kconfig" --- a/drivers/staging/fsl-dpaa2/Makefile +++ b/drivers/staging/fsl-dpaa2/Makefile @@ -5,3 +5,4 @@ obj-$(CONFIG_FSL_DPAA2_ETH) += ethernet/ obj-$(CONFIG_FSL_DPAA2_MAC) += mac/ obj-$(CONFIG_FSL_DPAA2_EVB) += evb/ +obj-$(CONFIG_FSL_DPAA2_ETHSW) += ethsw/ --- /dev/null +++ b/drivers/staging/fsl-dpaa2/ethsw/Kconfig @@ -0,0 +1,7 @@ +config FSL_DPAA2_ETHSW + tristate "DPAA2 Ethernet Switch" + depends on FSL_MC_BUS && FSL_DPAA2 && FSL_DPAA2_ETH + select FSL_DPAA2_MAC + default y + ---help--- + Prototype driver for DPAA2 Ethernet Switch. --- /dev/null +++ b/drivers/staging/fsl-dpaa2/ethsw/Makefile @@ -0,0 +1,10 @@ + +obj-$(CONFIG_FSL_DPAA2_ETHSW) += dpaa2-ethsw.o + +dpaa2-ethsw-objs := switch.o dpsw.o + +all: + make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules + +clean: + make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean --- /dev/null +++ b/drivers/staging/fsl-dpaa2/ethsw/dpsw-cmd.h @@ -0,0 +1,916 @@ +/* Copyright 2013-2015 Freescale Semiconductor Inc. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are met: + * * Redistributions of source code must retain the above copyright + * notice, this list of conditions and the following disclaimer. + * * Redistributions in binary form must reproduce the above copyright + * notice, this list of conditions and the following disclaimer in the + * documentation and/or other materials provided with the distribution. + * * Neither the name of the above-listed copyright holders nor the + * names of any contributors may be used to endorse or promote products + * derived from this software without specific prior written permission. + * + * + * ALTERNATIVELY, this software may be distributed under the terms of the + * GNU General Public License ("GPL") as published by the Free Software + * Foundation, either version 2 of that License or (at your option) any + * later version. + * + * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" + * AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE + * IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE + * ARE DISCLAIMED.
