Input: psmouse - rework setting of BTN_MIDDLE capability

2009-11-20T08:52:12Z

Do not start protocol detection assuming that middle mouse is present, instead let individual protocols explicitly set this capability. This fixes issue with Synaptics touchpads pretending that they have middle button when hardware clearly reports otherwise. Reported-and-tested-by: Andrey Borzenkov Signed-off-by: Dmitry Torokhov

Input: logips2pp - model 73 is actually TrackMan FX

Input: convert drivers to use strict_strtoul()

2008-09-10T16:11:57Z

strict_strtoul() allows newline character at the end of the the input string and therefore is more user-friendly. Signed-off-by: Dmitry Torokhov

Input: logips2pp - add type 72 (PS/2 TrackMan Marble)

2007-05-09T03:34:18Z

This is purely cosmetic: this is standard 3-button, no wheel or other such features, so it already _worked_ just fine. This patch suppresses a warning about the unknown model, and changes the printk from "Mouse" to "TrackMan". Signed-off-by: Peter Samuelson Signed-off-by: Dmitry Torokhov

Input: logips2pp - add model 1 information

2007-04-12T05:33:19Z

It turns out I had an old 2-button Logitech mouse that responds to Logitech's queries with model of 1. Signed-off-by: Dmitry Torokhov

Input: logips2pp - ignore mice reporting model as 0

2007-04-12T05:32:22Z

There are mice reporting to logitech's queries with model of 0. Do not claim that these are Logitech mice. Signed-off-by: Dmitry Torokhov

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers

2006-10-05T14:10:12Z

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. Signed-Off-By: David Howells (cherry picked from 1b16e7ac850969f38b375e511e3fa2f474a33867 commit)
