The WRITE index points 55to the _next_ packet to be written and is advanced when after the TBD has been 56filled. 57 58The firmware pulls from the TBD queue at the READ index. The READ index points 59to the currently being read entry, and is advanced once the firmware is 60done with a packet. 61 62When data is sent to the firmware, the first TBD is used to indicate to the 63firmware if a Command or Data is being sent. If it is Command, all of the 64command information is contained within the physical address referred to by the 65TBD. If it is Data, the first TBD indicates the type of data packet, number 66of fragments, etc. The next TBD then referrs to the actual packet location. 67 68The Tx flow cycle is as follows: 69 701) ipw2100_tx() is called by kernel with SKB to transmit 712) Packet is move from the tx_free_list and appended to the transmit pending 72 list (tx_pend_list) 733) work is scheduled to move pending packets into the shared circular queue. 744) when placing packet in the circular queue, the incoming SKB is DMA mapped 75 to a physical address. That address is entered into a TBD. Two TBDs are 76 filled out. The first indicating a data packet, the second referring to the 77 actual payload data. 785) the packet is removed from tx_pend_list and placed on the end of the 79 firmware pending list (fw_pend_list) 806) firmware is notified that the WRITE index has 817) Once the firmware has processed the TBD, INTA is triggered. 828) For each Tx interrupt received from the firmware, the READ index is checked 83 to see which TBDs are done being processed. 849) For each TBD that has been processed, the ISR pulls the oldest packet 85 from the fw_pend_list. 8610)The packet structure contained in the fw_pend_list is then used 87 to unmap the DMA address and to free the SKB originally passed to the driver 88 from the kernel. 8911)The packet structure is placed onto the tx_free_list 90 91The above steps are the same for commands, only the msg_free_list/msg_pend_list 92are used instead of tx_free_list/tx_pend_list 93 94... 95 96Critical Sections / Locking : 97 98There are two locks utilized. The first is the low level lock (priv->low_lock) 99that protects the following: 100 101- Access to the Tx/Rx queue lists via priv->low_lock. The lists are as follows: 102 103 tx_free_list : Holds pre-allocated Tx buffers. 104 TAIL modified in __ipw2100_tx_process() 105 HEAD modified in ipw2100_tx() 106 107 tx_pend_list : Holds used Tx buffers waiting to go into the TBD ring 108 TAIL modified ipw2100_tx() 109 HEAD modified by ipw2100_tx_send_data() 110 111 msg_free_list : Holds pre-allocated Msg (Command) buffers 112 TAIL modified in __ipw2100_tx_process() 113 HEAD modified in ipw2100_hw_send_command() 114 115 msg_pend_list : Holds used Msg buffers waiting to go into the TBD ring 116 TAIL modified in ipw2100_hw_send_command() 117 HEAD modified in ipw2100_tx_send_commands() 118 119 The flow of data on the TX side is as follows: 120 121 MSG_FREE_LIST + COMMAND => MSG_PEND_LIST => TBD => MSG_FREE_LIST 122 TX_FREE_LIST + DATA => TX_PEND_LIST => TBD => TX_FREE_LIST 123 124 The methods that work on the TBD ring are protected via priv->low_lock. 125 126- The internal data state of the device itself 127- Access to the firmware read/write indexes for the BD queues 128 and associated logic 129 130All external entry functions are locked with the priv->action_lock to ensure 131that only one external action is invoked at a time. 132 133 134*/ 135 136#include <linux/compiler.h> 137#include <linux/errno.h> 138#include <linux/if_arp.h> 139#include <linux/in6.h> 140#include <linux/in.h> 141#include <linux/ip.h> 142#include <linux/kernel.h> 143#include <linux/kmod.h> 144#include <linux/module.h> 145#include <linux/netdevice.h> 146#include <linux/ethtool.h> 147#include <linux/pci.h> 148#include <linux/dma-mapping.h> 149#include <linux/proc_fs.h> 150#include <linux/skbuff.h> 151#include <asm/uaccess.h> 152#include <asm/io.h> 153#include <linux/fs.h> 154#include <linux/mm.h> 155#include <linux/slab.h> 156#include <linux/unistd.h> 157#include <linux/stringify.h> 158#include <linux/tcp.h> 159#include <linux/types.h> 160#include <linux/time.h> 161#include <linux/firmware.h> 162#include <linux/acpi.h> 163#include <linux/ctype.h> 164#include <linux/pm_qos_params.h> 165 166#include <net/lib80211.h> 167 168#include "ipw2100.h" 169 170#define IPW2100_VERSION "git-1.2.2" 171 172#define DRV_NAME "ipw2100" 173#define DRV_VERSION IPW2100_VERSION 174#define DRV_DESCRIPTION "Intel(R) PRO/Wireless 2100 Network Driver" 175#define DRV_COPYRIGHT "Copyright(c) 2003-2006 Intel Corporation" 176 177/* Debugging stuff */ 178#ifdef CONFIG_IPW2100_DEBUG 179#define IPW2100_RX_DEBUG /* Reception debugging */ 180#endif 181 182MODULE_DESCRIPTION(DRV_DESCRIPTION); 183MODULE_VERSION(DRV_VERSION); 184MODULE_AUTHOR(DRV_COPYRIGHT); 185MODULE_LICENSE("GPL"); 186 187static int debug = 0; 188static int network_mode = 0; 189static int channel = 0; 190static int associate = 0; 191static int disable = 0; 192#ifdef CONFIG_PM 193static struct ipw2100_fw ipw2100_firmware; 194#endif 195 196#include <linux/moduleparam.h> 197module_param(debug, int, 0444); 198module_param_named(mode, network_mode, int, 0444); 199module_param(channel, int, 0444); 200module_param(associate, int, 0444); 201module_param(disable, int, 0444); 202 203MODULE_PARM_DESC(debug, "debug level"); 204MODULE_PARM_DESC(mode, "network mode (0=BSS,1=IBSS,2=Monitor)"); 205MODULE_PARM_DESC(channel, "channel"); 206MODULE_PARM_DESC(associate, "auto associate when scanning (default off)"); 207MODULE_PARM_DESC(disable, "manually disable the radio (default 0 [radio on])"); 208 209static u32 ipw2100_debug_level = IPW_DL_NONE; 210 211#ifdef CONFIG_IPW2100_DEBUG 212#define IPW_DEBUG(level, message...) \ 213do { \ 214 if (ipw2100_debug_level & (level)) { \ 215 printk(KERN_DEBUG "ipw2100: %c %s ", \ 216 in_interrupt() ?
