All Rights Reserved. Marcelo Tosatti <marcelo@conectiva.com.br> : Made it compile in 2.3 (device to net_device) Alan Cox <alan@redhat.com> : Cleaned up for kernel merge. Removed the back compatibility support Reformatted, fixing spelling etc as I went Removed IRQ 0-15 assumption Jeff Garzik <jgarzik@mandrakesoft.com> : Updated to use new PCI driver API. Resource usage cleanups. Report driver version to user. Tobias Ringstrom <tori@unhappy.mine.nu> : Cleaned up and added SMP safety. Thanks go to Jeff Garzik, Andrew Morton and Frank Davis for the SMP safety fixes. TODO Implement pci_driver::suspend() and pci_driver::resume() power management methods. Check and fix on 64bit and big endian boxes. Test and make sure PCI latency is now correct for all cases. */ #define DMFE_VERSION "1.36p1 (May 12, 2001)" #include <linux/module.h> #include <linux/kernel.h> #include <linux/sched.h> #include <linux/string.h> #include <linux/timer.h> #include <linux/ptrace.h> #include <linux/errno.h> #include <linux/ioport.h> #include <linux/malloc.h> #include <linux/interrupt.h> #include <linux/pci.h> #include <linux/init.h> #include <linux/version.h> #include <linux/netdevice.h> #include <linux/etherdevice.h> #include <linux/skbuff.h> #include <linux/delay.h> #include <linux/spinlock.h> #include <asm/processor.h> #include <asm/bitops.h> #include <asm/io.h> #include <asm/dma.h> #if BITS_PER_LONG == 64 #error FIXME: driver does not support 64-bit platforms #endif /* Board/System/Debug information/definition ---------------- */ #define PCI_DM9132_ID 0x91321282 /* Davicom DM9132 ID */ #define PCI_DM9102_ID 0x91021282 /* Davicom DM9102 ID */ #define PCI_DM9100_ID 0x91001282 /* Davicom DM9100 ID */ #define PCI_DM9009_ID 0x90091282 /* Davicom DM9009 ID */ #define DMFE_SUCC 0 #define DM9102_IO_SIZE 0x80 #define DM9102A_IO_SIZE 0x100 #define TX_MAX_SEND_CNT 0x1 /* Maximum tx packet per time */ #define TX_DESC_CNT 0x10 /* Allocated Tx descriptors */ #define RX_DESC_CNT 0x20 /* Allocated Rx descriptors */ #define TX_FREE_DESC_CNT (TX_DESC_CNT - 2) /* Max TX packet count */ #define TX_WAKE_DESC_CNT (TX_DESC_CNT - 3) /* TX wakeup count */ #define DESC_ALL_CNT (TX_DESC_CNT + RX_DESC_CNT) #define TX_BUF_ALLOC 0x600 #define RX_ALLOC_SIZE 0x620 #define DM910X_RESET 1 #define CR0_DEFAULT 0x00E00000 /* TX & RX burst mode */ #define CR6_DEFAULT 0x00080000 /* HD */ #define CR7_DEFAULT 0x180c1 #define CR15_DEFAULT 0x06 /* TxJabber RxWatchdog */ #define TDES0_ERR_MASK 0x4302 /* TXJT, LC, EC, FUE */ #define MAX_PACKET_SIZE 1514 #define DMFE_MAX_MULTICAST 14 #define RX_COPY_SIZE 100 #define MAX_CHECK_PACKET 0x8000 #define DM9801_NOISE_FLOOR 8 #define DM9802_NOISE_FLOOR 5 #define DMFE_10MHF 0 #define DMFE_100MHF 1 #define DMFE_10MFD 4 #define DMFE_100MFD 5 #define DMFE_AUTO 8 #define DMFE_1M_HPNA 0x10 #define DMFE_TXTH_72 0x400000 /* TX TH 72 byte */ #define DMFE_TXTH_96 0x404000 /* TX TH 96 byte */ #define DMFE_TXTH_128 0x0000 /* TX TH 128 byte */ #define DMFE_TXTH_256 0x4000 /* TX TH 256 byte */ #define DMFE_TXTH_512 0x8000 /* TX TH 512 byte */ #define DMFE_TXTH_1K 0xC000 /* TX TH 1K byte */ #define DMFE_TIMER_WUT (jiffies + HZ * 1)/* timer wakeup time : 1 second */ #define DMFE_TX_TIMEOUT ((3*HZ)/2) /* tx packet time-out time 1.5 s" */ #define DMFE_TX_KICK (HZ/2) /* tx packet Kick-out time 0.5 s" */ #define DMFE_DBUG(dbug_now, msg, value) if (dmfe_debug || (dbug_now)) printk(KERN_ERR "<DMFE>: %s %lx\n", (msg), (long) (value)) #define SHOW_MEDIA_TYPE(mode) printk(KERN_ERR "<DMFE>: Change Speed to %sMhz %s duplex\n",mode & 1 ?"100":"10", mode & 4 ?
