To accomodate the higher memory usage, each physical descriptor page is allocated separately and the software ring that keeps track of the SKBs and the DMA addresses is allocated using vmalloc. Some of the receive-related fields in the bp structure are re- organized a bit for better locality of reference. The max. was reduced to 1020 from 4080 after discussion with David Miller.

The + * BR/~D line on the chip is brought high to signal 'command mode', + * where a command byte is sent to select the baudrate of the RS232 + * interface and the pulse length of the IRDA output. When BR/~D + * is brought low, the dongle then changes to the selected baudrate, + * and the RS232 interface is used for data until BR/~D is brought + * high again. The initial speed for the TOIMx323 after RESET is + * 9600 baud. The baudrate for command-mode is the last selected + * baud-rate, or 9600 after a RESET. + * + * The dongle I have (below) adds some extra hardware on the front end, + * but this is mostly directed towards pariasitic power from the RS232 + * line rather than changing very much about how to communicate with + * the TOIM3232. + * + * The protocol to talk to the TOIM4232 chipset seems to be almost + * identical to the TOIM3232 (and the 4232 datasheet is more detailed) + * so this code will probably work on that as well, although I haven't + * tested it on that hardware. + * + * Target dongle variations that might be common: + * + * DTR and RTS function: + * The data sheet for the 4232 has a sample implementation that hooks the + * DTR and RTS lines to the RESET and BaudRate/~Data lines of the + * chip (through line-converters). Given both DTR and RTS would have to + * be held low in normal operation, and the TOIMx232 requires +5V to + * signal ground, most dongle designers would almost certainly choose + * an implementation that kept at least one of DTR or RTS high in + * normal operation to provide power to the dongle, but will likely + * vary between designs. + * + * User specified command bits: + * There are two user-controllable output lines from the TOIMx232 that + * can be set low or high by setting the appropriate bits in the + * high-nibble of the command byte (when setting speed and pulse length). + * These might be used to switch on and off added hardware or extra + * dongle features. + * + * + * Target hardware: IRWave IR320ST-2 + * + * The IRWave IR320ST-2 is a simple dongle based on the Vishay/Temic + * TOIM3232 SIR Endec and the Vishay/Temic TFDS4500 SIR IRDA transciever. + * It uses a hex inverter and some discrete components to buffer and + * line convert the RS232 down to 5V. + * + * The dongle is powered through a voltage regulator, fed by a large + * capacitor. To switch the dongle on, DTR is brought high to charge + * the capacitor and drive the voltage regulator. DTR isn't associated + * with any control lines on the TOIM3232. Parisitic power is also taken + * from the RTS, TD and RD lines when brought high, but through resistors. + * When DTR is low, the circuit might lose power even with RTS high. + * + * RTS is inverted and attached to the BR/~D input pin. When RTS + * is high, BR/~D is low, and the TOIM3232 is in the normal 'data' mode. + * RTS is brought low, BR/~D is high, and the TOIM3232 is in 'command + * mode'. + * + * For some unknown reason, the RESET line isn't actually connected + * to anything. This means to reset the dongle to get it to a known + * state (9600 baud) you must drop DTR and RTS low, wait for the power + * capacitor to discharge, and then bring DTR (and RTS for data mode) + * high again, and wait for the capacitor to charge, the power supply + * to stabilise, and the oscillator clock to stabilise. + * + * Fortunately, if the current baudrate is known, the chipset can + * easily change speed by entering command mode without having to + * reset the dongle first. + * + * Major Components: + * + * - Vishay/Temic TOIM3232 SIR Endec to change RS232 pulse timings + * to IRDA pulse timings + * - 3.6864MHz crystal to drive TOIM3232 clock oscillator + * - DM74lS04M Inverting Hex line buffer for RS232 input buffering + * and level conversion + * - PJ2951AC 150mA voltage regulator + * - Vishay/Temic TFDS4500 SIR IRDA front-end transceiver + * + */ + +#include +#include +#include + +#include + +#include "sir-dev.h" + +MODULE_PARM(toim3232delay, "i"); +MODULE_PARM_DESC(toim3232delay, "toim3232 dongle write complete delay"); +static int toim3232delay = 150; /* default is 150 ms */ + +#if 0 +MODULE_PARM(toim3232flipdtr, "i"); +MODULE_PARM_DESC(toim3232flipdtr, "toim3232 dongle invert DTR (Reset)"); +static int toim3232flipdtr = 0; /* default is DTR high to reset */ + +MODULE_PARM(toim3232fliptrs, "i"); +MODULE_PARM_DESC(toim3232fliprts, "toim3232 dongle invert RTS (BR/D)"); +static int toim3232fliprts = 0; /* default is RTS high for baud change */ +#endif + +static int toim3232_open(struct sir_dev *); +static int toim3232_close(struct sir_dev *); +static int toim3232_change_speed(struct sir_dev *, unsigned); +static int toim3232_reset(struct sir_dev *); + +#define TOIM3232_115200 0x00 +#define TOIM3232_57600 0x01 +#define TOIM3232_38400 0x02 +#define TOIM3232_19200 0x03 +#define TOIM3232_9600 0x06 +#define TOIM3232_2400 0x0A + +#define TOIM3232_PW 0x10 /* Pulse select bit */ + +static struct dongle_driver toim3232 = { + .owner = THIS_MODULE, + .driver_name = "Vishay TOIM3232", + .type = IRDA_TOIM3232_DONGLE, + .open = toim3232_open, + .close = toim3232_close, + .reset = toim3232_reset, + .set_speed = toim3232_change_speed, +}; + +static int __init toim3232_sir_init(void) +{ + if (toim3232delay < 1 || toim3232delay > 500) + toim3232delay = 200; + IRDA_DEBUG(1, "%s - using %d ms delay\n", + toim3232.driver_name, toim3232delay); + return irda_register_dongle(&toim3232); +} + +static void __exit toim3232_sir_cleanup(void) +{ + irda_unregister_dongle(&toim3232); +} + +static int toim3232_open(struct sir_dev *dev) +{ + struct qos_info *qos = &dev->qos; + + IRDA_DEBUG(2, "%s()\n", __FUNCTION__); + + /* Pull the lines high to start with. + * + * For the IR320ST-2, we need to charge the main supply capacitor to + * switch the device on.

I was getting a panic after a tg3 device failed to initialize due to DMA failure. The oops pointed to the link watch queue with spinlock debugging enabled. Without spinlock debugging, the Oops didn't occur. I suspect that the link event was getting queued but not executed until after the DMA test had failed and the device was freed. The link event was then operating on freed memory, which could contain anything. With this patch applied, the Oops no longer occurs.

We can merge these two operations into one function with skb_pull_rcsum. This makes sense since most pull operations on receive skb's need to update the checksum. I've decided to make this out-of-line since it is fairly big and the fast path where hardware checksums are enabled need to call csum_partial anyway. Since this is a brand new function we get to add an extra check on the len argument. As it is most callers of skb_pull ignore its return value which essentially means that there is no check on the len argument. Signed-off-by: Herbert Xu Signed-off-by: David S.

This has many advantages such as allowing the compiler to validate the syntax of the whole code, making it cleaner and easier to understand, and ultimately allowing people to define configuration symbols in terms of variables if they really want to dynamically support multiple bus configurations at the same time (with the unavoidable performance cost).

This is the completion of the RtNetlink work I started early 2004, it enables the full Wireless Extension API over RtNetlink. Few comments on the patch : o totally driver transparent, no change in drivers needed. o iwevent were already RtNetlink based since they were created (around 2.5.7). This adds all the regular SET and GET requests over RtNetlink, using the exact same mechanism and data format as iwevents. o This is a Kconfig option, as currently most people have no need for it. Surprisingly, patch is actually small and well encapsulated. o Tested on SMP, attention as been paid to make it 64 bits clean. o Code do probably too many checks and could be further optimised, but better safe than sorry. o RtNetlink based version of the Wireless Tools available on my web page for people inclined to try out this stuff. I would also like to thank Alexey Kuznetsov for his helpful suggestions to make this patch better. Signed-off-by: Jean Tourrilhes Signed-off-by: John W.

The correct way of doing this is to test cpu_possible() or to use for_each_cpu(). This patch is a kernel-wide sweep of all instances of NR_CPUS. I found very few instances of this bug, if any. But the patch converts lots of open-coded test to use the preferred helper macros.
