avoid overflows in kernel/time.c
When the conversion factor between jiffies and milli- or microseconds is
not a single multiply or divide, as for the case of HZ == 300, we currently
do a multiply followed by a divide. The intervening result, however, is
subject to overflows, especially since the fraction is not simplified (for
HZ == 300, we multiply by 300 and divide by 1000).
This is exposed to the user when passing a large timeout to poll(), for
example.
This patch replaces the multiply-divide with a reciprocal multiplication on
32-bit platforms. When the input is an unsigned long, there is no portable
way to do this on 64-bit platforms there is no portable way to do this
since it requires a 128-bit intermediate result (which gcc does support on
64-bit platforms but may generate libgcc calls, e.g. on 64-bit s390), but
since the output is a 32-bit integer in the cases affected, just simplify
the multiply-divide (*3/10 instead of *300/1000).
The reciprocal multiply used can have off-by-one errors in the upper half
of the valid output range. This could be avoided at the expense of having
to deal with a potential 65-bit intermediate result. Since the intent is
to avoid overflow problems and most of the other time conversions are only
semiexact, the off-by-one errors were considered an acceptable tradeoff.
At Ralf Baechle's suggestion, this version uses a Perl script to compute
the necessary constants. We already have dependencies on Perl for kernel
compiles. This does, however, require the Perl module Math::BigInt, which
is included in the standard Perl distribution starting with version 5.8.0.
In order to support older versions of Perl, include a table of canned
constants in the script itself, and structure the script so that
Math::BigInt isn't required if pulling values from said table.
Running the script requires that the HZ value is available from the
Makefile. Thus, this patch also adds the Kconfig variable CONFIG_HZ to the
architectures which didn't already have it (alpha, cris, frv, h8300, m32r,
m68k, m68knommu, sparc, v850, and xtensa.) It does *not* touch the sh or
sh64 architectures, since Paul Mundt has dealt with those separately in the
sh tree.

This option prevents any floating-point instructions from being

compiled into the kernel, thereby the kernel doesn't save any

|
floating point context anymore during task switches, so this
|
|
|
|
|
kernel will only be usable on machines without a floating-point
|
|

math coprocessor. This makes the kernel a bit faster as no tests

needs to be executed whether a floating-point instruction in the

The 68060 generally uses copyback caching of recently accessed data.
|

Copyback caching means that memory writes will be held in an on-chip
|

|
cache and only written back to memory some time later. Saying Y
|
|
|

here will force supervisor (kernel) accesses to use writethrough

caching. Writethrough caching means that data is written to memory
|
|
|
|
|
straight away, so that cache and memory data always agree.
|

Writethrough caching is less efficient, but is needed for some

If you say Y here, it will be possible to use a serial port as the
|
|
|
|
|
system console (the system console is the device which receives all
|
|
|
|
|
kernel messages and warnings and which allows logins in single user
|
|
|
|
|
mode). This could be useful if some terminal or printer is connected
|
|
|
|
|
to that serial port.
|
|
|
|
|
|
|
|
|
|
Even if you say Y here, the currently visible virtual console
|
|
|
|
|
(/dev/tty0) will still be used as the system console by default, but
|
|
|
|
|
you can alter that using a kernel command line option such as
|
|
|
|
|
"console=ttyS1". (Try "man bootparam" or see the documentation of
|
|
|
|
|
your boot loader (lilo or loadlin) about how to pass options to the
|
|
|
|
|
kernel at boot time.)
|
|
|
|
|
|
|
|
|
|
If you don't have a VGA card installed and you say Y here, the
|
|
|
|
|
kernel will automatically use the first serial line, /dev/ttyS0, as
|
|
|
|
|
system console.
|
|
|
|
|
|
|
|
|
|
If unsure, say N.
