The sysfs adsl_status attribute ignores (aside from returning -EIO to the user) any error sending a START/STOP command to the device and there is at least one firmware which never sends a response but appears to work regardless. Therefore atm_start should also continue if an error is received so that such firmware is usable. The official Conexant driver doesn't expect a reply either but this is for another device (E2 router) and a commonly used firmware does respond. Also, there is no point in changing -ECONNRESET to -ETIMEDOUT since nothing ever checks for either of these values.

Since usbatm doesn't set the usb_interface driver data until after calling bind and heavy_init, it would be NULL when the sysfs attributes are read. Reading the MAC address from atm_dev before atm_dev exists would have been be possible too. Calling create_device_file in atm_start will avoid this problem, and the data is useless until the first status poll runs. However, it must be ready before a status poll does a printk on line status change otherwise userspace could react before the files exist. For completeness I've moved remove_device_file to atm_stop so it's not called in unbind when it's not needed. There's no point starting ADSL if atm_start could still fail either.

The device has commands to start/stop the ADSL function, so this adds a sysfs attribute to allow it to be started/stopped/restarted. It also stops polling the device for status when the ADSL function is disabled. There are no problems with sending multiple start or stop commands, even with a fast loop of them the device still works. There is no need to protect the restart process from further user actions while it's waiting for 1.5s.

When the device is polled for status there is a lot of useful status information available that is ignored. This patch stores the device info array when the status is polled and adds sysfs files to the usb device to allow userspace to query it. Since the device updates its status internally once a second the poll time is changed to this, and round_jiffies_relative is used to avoid waking the cpu unnecessarily.

There is currently no path from the ATM device in /sys to the USB device's interface that the driver is using; this patch creates a "device" symlink. It is then possible to get to the cxacru ADSL statistics (http://lkml.org/lkml/2007/2/23/328): /sys/class/atm/cxacru0/device $ ls *_rate *_margin *_attenuation downstream_attenuation downstream_snr_margin upstream_rate downstream_rate upstream_attenuation upstream_snr_margin If this link is not appropriate I'd have to create device files in /sys/class/atm/cxacru0 instead - which seems less appropriate since the ADSL statistics are for the USB device not ATM (which is running over the ADSL).

So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes on 64bit architectures, allowing us to combine the 4 bytes hole left by the layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4 64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN... :-) Many calculations that previously required that skb->{transport,network, mac}_header be first converted to a pointer now can be done directly, being meaningful as offsets or pointers.

The speedtouch modem setup code was reverse engineered many years ago from a prehistoric windows driver. Less ancient windows drivers, even those from a few years ago, perform extra initialization steps which this patch adds to the linux driver. David Woodhouse observed that this initialization along with the firmware bin/sachu3/zzzlp2.eni from the driver at http://www.speedtouch.co.uk/downloads/330/301/UK3012%20Extended.zip improves line sync speeds by about 20%. He provided the original patch, which I've modified to use symbolic names (BMaxDSL, ModemMode, ModemOption) rather than magic numbers. These names may not seem like much of an improvement (after all, what is "ModemOption" exactly?), but they do have one big advantage: they are the names used in the windows registry. I've made them available as module parameters. Thanks are due to Aurelio Arroyo, who noticed the relationship between these magic numbers and the entries in Phonebook.ini.

Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

The maximum possible bandwidth for a speedtouch modem is about 7Mbaud. You can only get this by using isochronous urbs (enable_isoc=1) and altsetting 3. With the current default altsetting of 2, the modem maxes out at about 4Mbaud. So change the default altsetting to 3 when using isochronous urbs. It would be nice to base the altsetting on the detected line speed, but that's hard given the current design.

This patch adds the support for isochronous pipe. A new module parameter is added to select iso mode. It is set to iso by default because bulk mode doesn't work well at high speed rate (>3 Mbps for upload). We use UDSL_IGNORE_EILSEQ flags because ADI firmware doesn't reply to ISO IN when it has nothing to send [1]. [1] from cypress datasheet : The ISOSEND0 Bit (bit 7 in the USBPAIR Register) is used when the EZ-USB FX chip receives an isochronous IN token while the IN FIFO is empty. If ISOSEND0=0 (the default value), the USB core does not respond to the IN token. If ISOSEND0=1, the USB core sends a zero-length data packet in response to the IN token. The action to take depends on the overall system design. The ISOSEND0 Bit applies to all of the isochronous IN endpoints, IN-8 through IN-15.
