2008-11-12netdevice: safe convert to netdev_priv() #part-2Wang Chen
We have some reasons to kill netdev->priv: 1. netdev->priv is equal to netdev_priv(). 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously netdev_priv() is more flexible than netdev->priv. But we cann't kill netdev->priv, because so many drivers reference to it directly. This patch is a safe convert for netdev->priv to netdev_priv(netdev). Since all of the netdev->priv is only for read. But it is too big to be sent in one mail. I split it to 4 parts and make every part smaller than 100,000 bytes, which is max size allowed by vger.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
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.

2006-09-27USB: Dealias -110 code (more complete)Pete Zaitcev
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.

2006-02-19[IRDA]: irda-usb bug fixesJean Tourrilhes
This patch fixes 2 bugs in the USB-IrDA code. The first one is a buffer overrun in the RX path. We are now using IRDA_SKB_MAX_MTU when initializing the Rx URB. The second one is a potential stack recursion when unplugging the USB dongle. It seems that first we get the Rx URB with a generic error code, and after a while the Rx URB comes again with a "disconnect" error code. Since we are resubmitting the Rx URB immediately after receiving the first error one, we might enter an endless loop. When getting an error Rx URB, the patch defers the Rx URB resubmitting so that it gives us a chance to catch the disconnect one, in case the dongle has juts been unplugged. Tested against 2.6.16-rc2.

2005-09-08[PATCH] USB: URB_ASYNC_UNLINK flag removed from the kernelAlan Stern
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."

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!
