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.

The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping.
|
|
|
|
You can operate a Linux system on this board by using an M32R
|
|
|
|
softmacro core, which is a fully-synthesizable functional model
|
|
|
|
described in Verilog-HDL.
|
|
|
|
|
|
|
|
The Mappi-I board was the first platform, which had been used
|
|
|
|
to port and develop a Linux system for the M32R processor.
|
|
|
|
Currently, the Mappi-II, an heir to the Mappi-I, is available.

m32r: fix switch_to macro to push/pop frame pointer if needed
This patch fixes a rarely-happened but severe scheduling problem of
the recent m32r kernel of 2.6.17-rc3 or later.
In the following previous m32r patch, the switch_to macro was
modified not to do unnecessary push/pop operations for tuning.
> [PATCH] m32r: update switch_to macro for tuning
> 4127272c38619c56f0c1aa01d01c7bd757db70a1
In this modification, only 'lr' and 'sp' registers are push/pop'ed,
assuming that the m32r kernel is always compiled with
-fomit-frame-pointer option.
However, in 2.6 kernel, kernel/sched.c is irregularly compiled
with -fno-omit-frame-pointer if CONFIG_SCHED_NO_NO_OMIT_FRAME_POINTER
is not defined.
-- kernel/Makefile --
:
ifneq ($(CONFIG_SCHED_NO_NO_OMIT_FRAME_POINTER),y)
# According to Alan Modra <alan@linuxcare.com.au>, the -fno-omit-frame-pointer is
# needed for x86 only. Why this used to be enabled for all architectures is beyond
# me. I suspect most platforms don't need this, but until we know that for sure
# I turn this off for IA-64 only. Andreas Schwab says it's also needed on m68k
# to get a correct value for the wait-channel (WCHAN in ps). --davidm
CFLAGS_sched.o := $(PROFILING) -fno-omit-frame-pointer
endif
:
---
Therefore, for the recent m32r kernel, we have to push/pop 'fp'
(frame pointer) if CONFIG_FRAME_POINTER is defined or
CONFIG_SCHED_NO_NO_OMIT_FRAME_POINTER is not defined.

This allows you to specify the maximum number of CPUs which this
|
|
|
|
kernel will support. The maximum supported value is 32 and the
|
|
|
|
minimum value which makes sense is 2.
|

|

|
This is purely to save memory - each supported CPU adds
|
|
|
|
approximately eight kilobytes to the kernel image.

Find out whether you have a PCI motherboard. PCI is the name of a
|
|
|
|
bus system, i.e. the way the CPU talks to the other stuff inside
|
|
|
|
your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
|
|
|
|
VESA. If you have PCI, say Y, otherwise N.

|
|
On PCI systems, the BIOS can be used to detect the PCI devices and
|
|
|
|
determine their configuration. However, some old PCI motherboards
|
|
|
|
have BIOS bugs and may crash if this is done. Also, some embedded
|
|
|
|
PCI-based systems don't have any BIOS at all. Linux can also try to
|
|
|
|
detect the PCI hardware directly without using the BIOS.
|
|
|
|
|
|
|
|
With this option, you can specify how Linux should detect the PCI
|
|
|
|
devices. If you choose "BIOS", the BIOS will be used, if you choose
|
|
|
|
"Direct", the BIOS won't be used, and if you choose "Any", the
|
|
|
|
kernel will try the direct access method and falls back to the BIOS
|
|
|
|
if that doesn't work. If unsure, go with the default, which is
|
|

"Any".
