From 17c7b6c3fdc48301e50d22cc6138ede16bd1be24 Mon Sep 17 00:00:00 2001 From: nbd Date: Thu, 6 Sep 2007 16:27:37 +0000 Subject: strip the kernel version suffix from target directories, except for brcm-2.4 (the -2.4 will be included in the board name here). CONFIG_LINUX__ becomes CONFIG_TARGET_, same for profiles. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@8653 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- target/linux/adm5120/files/drivers/net/adm5120sw.c | 625 +++++++++++++++++++++ target/linux/adm5120/files/drivers/net/adm5120sw.h | 114 ++++ 2 files changed, 739 insertions(+) create mode 100644 target/linux/adm5120/files/drivers/net/adm5120sw.c create mode 100644 target/linux/adm5120/files/drivers/net/adm5120sw.h (limited to 'target/linux/adm5120/files/drivers/net') diff --git a/target/linux/adm5120/files/drivers/net/adm5120sw.c b/target/linux/adm5120/files/drivers/net/adm5120sw.c new file mode 100644 index 000000000..80c81abf7 --- /dev/null +++ b/target/linux/adm5120/files/drivers/net/adm5120sw.c @@ -0,0 +1,625 @@ +/* + * ADM5120 built in ethernet switch driver + * + * Copyright Jeroen Vreeken (pe1rxq@amsat.org), 2005 + * + * Inspiration for this driver came from the original ADMtek 2.4 + * driver, Copyright ADMtek Inc. + * + * NAPI extensions by Thomas Langer (Thomas.Langer@infineon.com) + * and Friedrich Beckmann (Friedrich.Beckmann@infineon.com), 2007 + * + * TODO: Add support of high prio queues (currently disabled) + * + */ +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include "adm5120sw.h" + +#include +#include + +MODULE_AUTHOR("Jeroen Vreeken (pe1rxq@amsat.org)"); +MODULE_DESCRIPTION("ADM5120 ethernet switch driver"); +MODULE_LICENSE("GPL"); + +/* default settings - unlimited TX and RX on all ports, default shaper mode */ +static unsigned char bw_matrix[SW_DEVS] = { + 0, 0, 0, 0, 0, 0 +}; + +static int adm5120_nrdevs; + +static struct net_device *adm5120_devs[SW_DEVS]; +/* Lookup table port -> device */ +static struct net_device *adm5120_port[SW_DEVS]; + +static struct adm5120_dma + adm5120_dma_txh_v[ADM5120_DMA_TXH] __attribute__((aligned(16))), + adm5120_dma_txl_v[ADM5120_DMA_TXL] __attribute__((aligned(16))), + adm5120_dma_rxh_v[ADM5120_DMA_RXH] __attribute__((aligned(16))), + adm5120_dma_rxl_v[ADM5120_DMA_RXL] __attribute__((aligned(16))), + *adm5120_dma_txh, + *adm5120_dma_txl, + *adm5120_dma_rxh, + *adm5120_dma_rxl; +static struct sk_buff + *adm5120_skb_rxh[ADM5120_DMA_RXH], + *adm5120_skb_rxl[ADM5120_DMA_RXL], + *adm5120_skb_txh[ADM5120_DMA_TXH], + *adm5120_skb_txl[ADM5120_DMA_TXL]; +static int adm5120_rxli = 0; +static int adm5120_txli = 0; +/*static int adm5120_txhi = 0;*/ +static int adm5120_if_open = 0; + +static inline void adm5120_set_reg(unsigned int reg, unsigned long val) +{ + *(volatile unsigned long*)(SW_BASE+reg) = val; +} + +static inline unsigned long adm5120_get_reg(unsigned int reg) +{ + return *(volatile unsigned long*)(SW_BASE+reg); +} + +static inline void adm5120_rx_dma_update(struct adm5120_dma *dma, + struct sk_buff *skb, int end) +{ + dma->status = 0; + dma->cntl = 0; + dma->len = ADM5120_DMA_RXSIZE; + dma->data = ADM5120_DMA_ADDR(skb->data) | + ADM5120_DMA_OWN | (end ?
