* Move USB network drivers to drivers/net/usb.Jeff Garzik2007-05-09
| | | | | | | | | | | | It is preferable to group drivers by usage (net, scsi, ATA, ...) than by bus. When reviewing drivers, the [PCI|USB|PCMCIA|...] maintainer is probably less qualified on networking issues than a networking maintainer. Also, from a practical standpoint, chips often appear on multiple buses, which is why we do not put drivers into drivers/pci/net.

* usb-net/pegasus: fix pegasus carrier detectionDan Williams2007-04-24
| | | | | | | | | | | | | | | | | Broken by 4a1728a28a193aa388900714bbb1f375e08a6d8e which switched the return semantics of read_mii_word() but didn't fix usage of read_mii_word() to conform to the new semantics. Setting carrier to off based on the NO_CARRIER flag is also incorrect as that flag only triggers on TX failure and therefore isn't correct when no frames are being transmitted. Since there is already a 2*HZ MII carrier check going on, defer to that. Add a TRUST_LINK_STATUS feature flag for adapters where the LINK_STATUS flag is actually correct, and use that rather than the NO_CARRIER flag.

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* USB: Pegasus driver failing for ADMtek 8515 network devicePetko Manolov2006-09-28
| | | | | | | | | | | | | | | | | | | | | Address http://bugzilla.kernel.org/show_bug.cgi?id=7126 Attempting to read the ethernet ID directly from the eeprom somehow confuses ADM8515. Subsequent read requests to either the eeprom or the MII fail as well. Didn't dig much deeper, though. For example ADM8513 does not experience this problem. I used the fact that at power up the device is reading its ID automatically (not true for older Pegasus based devices) and put it in the Ethernet ID registers. So now the driver uses get_registers() instead of read_eprom_word() if the device is Pegasus_II based one. Tested it with all (Pegasus and Pegasus_II) gadgets i have and everything seems ok.

* USB: Dealias -110 code (more complete)Pete Zaitcev2006-09-27
| | | | | | | | | | | | | | | | | | | The purpose of this patch is to split off the case when a device does not reply on the lower level (which is reported by HC hardware), and a case when the device accepted the request, but does not reply at upper level. This redefinition allows to diagnose issues easier, without asking the user if the -110 happened "immediately". The usbmon splits such cases already thanks to its timestamp, but it's not always available. I adjusted all drivers which I found affected (by searching for "urb"). Out of tree drivers may suffer a little bit, but I do not expect much breakage. At worst they may print a few messages.

* [PATCH] usb_interface power stateDavid Brownell2005-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This updates the handling of power state for USB interfaces. - Formalizes an existing invariant: interface "power state" is a boolean: ON when I/O is allowed, and FREEZE otherwise. It does so by defining some inlined helpers, then using them. - Adds a useful invariant: the only interfaces marked active are those bound to non-suspended drivers. Later patches build on this invariant. - Simplifies the interface driver API (and removes some error paths) by removing the requirement that they record power state changes during suspend and resume callbacks. Now usbcore does that. A few drivers were simplified to address that last change.

* [PATCH] USB: fix pegasus driverKevin Vigor2005-09-22
| | | | | | | | | | | | | | | Addresses some small bugs in the pegasus ethernet-over-USB driver. Specifically, malformed long packets from the adapter could cause a kernel panic; the interrupt interval calculation was inappropriate for high-speed devices; the return code from read_mii_word was tested incorrectly; and failure to unlink outstanding URBs before freeing them could lead to kernel panics when unloading the driver.

* [PATCH] USB: URB_ASYNC_UNLINK flag removed from the kernelAlan Stern2005-09-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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."

(As should stir4200...) * pegasus * usbnet Note that the Wake-On-Lan (WOL) support in pegasus doesn't yet work; looks to me like it's missing a request to turn it on, vs just configuring it.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
