When an error occurs, existing logging uses dbg() so the cause of a problem is hard to determine. Error conditions shouldn't only be properly reported with debugging enabled. A side effect of this change is that when an uninitialised device is started, a log message similar to the following is sent: cxacru 5-2:1.0: receive of cm 0x90 failed (-104) This is normal - the device did not respond so firmware will be loaded.

it seems like you overdid it a bit in your quest to clean up the use of urb->status. In this driver you read it the first thing, which means that you are in a race against URB completion you'll usually lose, returning -EINPROGRESS. This kills the driver.

This changes the format of unknown status values to be less verbose and uses an array instead of several different snprintf calls. Since only enum values are assigned to it, poll_state is changed from int to enum. Use abs() for dB values instead of two almost identical return lines.

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.

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.

While the usbatm core has had some support for using isoc urbs for some time, there was no way for users to turn it on. While use of isoc transfer should still be considered experimental, it now works well enough to let users turn it on. Minidrivers signal to the core that they want to use isoc transfer by setting the new UDSL_USE_ISOC flag. The speedtch minidriver gets a new module parameter enable_isoc (defaults to false), plus some logic that checks for the existence of an isoc receive endpoint (not all speedtouch modems have one).

由 Alan Stern 提交于
29 July 2005, Cambridge, MA: This afternoon Alan Stern submitted a patch to remove the URB_ASYNC_UNLINK flag from the Linux kernel. Mr. Stern explained, "This flag is a relic from an earlier, less-well-designed system. For over a year it hasn't been used for anything other than printing warning messages." An anonymous spokesman for the Linux kernel development community commented, "This is exactly the sort of thing we see happening all the time. As the kernel evolves, support for old techniques and old code can be jettisoned and replaced by newer, better approaches. Proprietary operating systems do not have the freedom or flexibility to change so quickly." Mr. Stern, a staff member at Harvard University's Rowland Institute who works on Linux only as a hobby, noted that the patch (labelled as548) did not update two files, keyspan.c and option.c, in the USB drivers' "serial" subdirectory. "Those files need more extensive changes," he remarked. "They examine the status field of several URBs at times when they're not supposed to. That will need to be fixed before the URB_ASYNC_UNLINK flag is removed." Greg Kroah-Hartman, the kernel maintainer responsible for overseeing all of Linux's USB drivers, did not respond to our inquiries or return our calls. His only comment was "Applied, thanks."
