2010-04-19Input: psmouse - ignore parity error for basic protocolsDmitry Torokhov
Observing behavior of the other OS it appears that parity errors reported by the keyboard controller are being ignored and the data is processed as usual. Let's do the same for standard PS/2 protocols (bare, Intellimouse and Intellimouse Explorer) to provide better compatibility. Thsi should fix teh following bug: https://bugzilla.kernel.org/show_bug.cgi?id=6105 Thanks for Damjan Jovanovic for locating the source of issue and ideas for the patch.

This is version 5 of the driver. Relative mode support has been dropped (users wishing to use touchpad in relative mode can use standard PS/2 protocol emulation done in hardware). The driver supports both original version of Elantech protocol and the newer one used by touchpads installed in EeePC.

2008-09-21Input: psmouse - add OLPC touchpad driverAndres Salomon
This adds support for OLPC's touchpad. It has lots of neat features, none of which are enabled because the hardware is too buggy. Instead, we use it like a normal touchpad, but with a number of workarounds in place to deal with the frequent hardware spasms. Humidity changes, sweat, tinfoil underwear, plugging in AC, drinks, evil felines.. All tend to cause the touchpad to freak out.

2008-09-21Input: psmouse - tweak PSMOUSE_DEFINE_ATTR to support raw set callbacksAndres Salomon
We want to support attr->set callbacks that may need psmouse->state to not be updated, or may want to manually deal w/ enabling and disabling the device. To do that, we create __PSMOUSE_DEFINE_ATTR which enables us to set a 'protect' argument specifying whether or not the set callback should be protected with psmouse_disable and state setting.

psmouse_queue_work is passed a delayed_work struct, and queues up the work with kpsmouse_wq. Since we're dealing with delayed_work stuff, this also switches resync_work to a delayed_work struct as well, and makes use of psmouse_queue_work when doing a resync within psmouse-base.

2007-07-11sysfs: kill unnecessary attribute->ownerTejun Heo
sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded. For more info regarding lifetime rule cleanup, please read the following message. http://article.gmane.org/gmane.linux.kernel/510293 (tweaked by Greg to not delete the field just yet, to make it easier to merge things properly.)

2007-07-10Input: psmouse - add support for Cortron PS/2 TrackballsAristeu Rozanski
Cortron PS/2 Trackballs (700-0001A) report the 4th button using the 4th bit of the first packet (yes, it breaks the standard PS/2 protocol). This patch adds an extra protocol to generate BTN_SIDE based on the 4th bit. There's no way to detect those trackballs using any kind of special sequence, thus the protocol must be activated explicitely by writing into 'protocol' sysfs attribute: echo -n "cortps" > /sys/devices/platform/i8042/serio1/protocol Signed-off-by: Aristeu Rozanski <arozansk@redhat.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

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.

2003-12-18[PATCH] Synaptics: use serio_reconnectDmitry Torokhov
Input/Synaptics: 1. Support for pass-through port moved from Synaptics driver to psmouse itself, it is cleaner and should allow using it in other drivers if needed. 2. The driver makes use of new reconnect functionality in serio. It will try to keep the same input device after resume or when it resets itself. 3. If mouse is disconnected or other mouse plugged in while sleeping the driver should correctly recognize that and create a new serio/input device.
