      USB: correct keymapping on Powerbook built-in USB ISO keyboards · bb7eef6e
      由 Olaf Hering 提交于 
      similar to the version in adbhid_input_register(): The '<>' key and the
'^°' key on a german keyboard is swapped.  Provide correct keys to
userland, external USB keyboards will not work correctly when the
'badmap'/'goodmap' workarounds from xkeyboard-config are used.

It is expected that distributions drop the badmap/goodmap part from
keycodes/macintosh in the xkeyboard-config package.

This is probably 2.6.18.x material, if major distros settle on 2.6.18.

      Input: HID - add a quirk for the Logitech USB Receiver · 41ad5fba
      由 Anssi Hannula 提交于 
      Logitech USB Receiver (046d:c101) has two interfaces. The first one
contains fields from HID_UP_KEYBOARD and HID_UP_LED, and the other one
contains fields from HID_UP_CONSUMER and HID_UP_LOGIVENDOR. This device
is used with multiple wireless Logitech products, including UltraX Media
Remote.

All fields on both interfaces are either keys or leds. All fields in the
first interface are marked as Absolute, while the fields in the second
interface are marked as Relative. Marking the keys as relative causes
hidinput_hid_event() to send release events right after key press
events.

The device has EV_REP set, so the userspace expects the device to send
repeat events if a key is held down. However, as hidinput_hid_event()
sends release events immediately, repeat events are not sent at all. In
fact, the userspace has no way of knowing if a key is being held down.

Fix this by adding a quirk for 046d:c101 which changes relative keys to
absolute ones.

      IRQ: Maintain regs pointer globally rather than passing to IRQ handlers · 7d12e780
      由 David Howells 提交于 
      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.

      [PATCH] usbhid: automatically set HID_QUIRK_NOGET for keyboards and mice · 0f28b55d
      由 Alan Stern 提交于 
      It seems to be relatively common for USB keyboards and mice to dislike
being polled for reports.  Since there's no need to poll a keyboard or
a mouse, this patch (as685) automatically sets the HID_QUIRK_NOGET flag
for devices that advertise themselves as either sort of device with boot
protocol support.

This won't cure all the problems since some devices don't support the
boot protocol, but it's simple and easy and it should fix quite a few
problems.

      [PATCH] USB HID/HIDBP, INPUT DRIVERS: fix various usb/input/hid-input.c bugs... · a82e49b8
      由 Bart Massey 提交于 
      [PATCH] USB HID/HIDBP, INPUT DRIVERS: fix various usb/input/hid-input.c bugs that make Apple Mighty Mouse work poorly

Transposed lines of code in drivers/usb/input/hid-input.c causes the
capability bits for a new HID device to be set before quirks are applied
at configuration time.  When an HID event is then sent up to the input
layer, it may then be discarded as irrelevant because the wrong
capability bit is set.

Further, the quirks for the Apple Mighty Mouse are not quite right: the
horizontal scrolling needs its axis reversed, and the left and center
buttons are transposed.  Also, the mouse is labeled in the kernel with
its earlier name (I think) of Apple PowerMouse.

Steps to reproduce problem: Plug in an Apple Mighty Mouse.  Note that
horizontal scrolling doesn't work at all, and in fact doesn't generate
any input events on /dev/input/eventN.  Note also that pushing the
middle button performs the right button action, and vice versa.  Once
you have the horizontal scrolling working, note that it is backward WRT
both to vertical scrolling and to common sense.

This patch maybe should be broken up, as it does address two problems.
The transposed code in hidinput_configure_usage() probably creates bugs
beyond just the Mighty Mouse.  The rest of the patch renames POWERMOUSE
to MIGHTYMOUSE everywhere (which I *believe* is correct), fixes the
MIGHTYMOUSE quirk to swap the center and right mouse buttons, and adds a
new quirk HID_QUIRK_INVERT_HWHEEL also assigned to the MIGHTYMOUSE with
code in hidinput_hid_event() to implement it.

      Linux-2.6.12-rc2 · 1da177e4
      由 Linus Torvalds 提交于 
      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!
