x86/asm/tsc: Rename native_read_tsc() to rdtsc()

2015-07-06T13:23:28+00:00

Now that there is no paravirt TSC, the "native" is
inappropriate. The function does RDTSC, so give it the obvious
name: rdtsc().

x86/asm/tsc, input/joystick/analog: Switch from rdtscl() to native_read_tsc()

2015-07-06T13:23:28+00:00

This timing code is hideous, and this doesn't help.  It gets rid
of one of the last users of rdtscl(), though.

Input: joystick - use ktime for measuring timing

2014-09-12T06:41:18+00:00

The current codes in gameport and analog joystick drivers for the time
accounting have a long-standing problem when the system is running
with CPU freq; since the timing is measured via TSC or sample counter,
the calculation isn't reliable.

In this patch, as a simple fix, use the standard ktime to measure the
timing.  In case where no high resolution timer is available,
use_ktime bool option is provided to both modules.  Setting
use_ktime=false switches to the old methods.

Input: joystick - use get_cycles on ARMv8

2014-08-12T16:59:40+00:00

As with ARM the ARMv8 architecture provides a cycle counter which can be
used to provide a high resolution time for the joystick driver and
silence the build warning that results from not having a precise timer
on ARMv8, making allmodconfig and allyesconfig quieter.

input/joystick: use get_cycles on ARM

2013-03-14T21:38:20+00:00

ARM normally has an accurate clock source, so
we can theoretically use analog joysticks more
accurately and at the same time avoid the
build warning

 #warning Precise timer not defined for this architecture.

from the joystick driver.

Now, why anybody would use that driver no ARM I have no
idea, but Ben Dooks enabled it in the s3c2410_defconfig
along with a bunch of other drivers, even though that
platform has neither ISA nor PCI support. It still
seems to be the right thing to fix this quirk.

drivers/input/joystick/analog.c: enable precise timer

Like nm10300, tile can just use get_cycles() for this.

Input: remove CLOCK_TICK_RATE from analog joystick driver

2011-08-05T06:41:36+00:00

The analog joystick driver is written for x86 systems. This
patch updates it to use the PIT_TICK_RATE value instead of
CLOCK_TICK_RATE as they are equivalent on x86 and we want to
deprecate the latter.
