MIPS: Tracing: Add dynamic function tracer support
With dynamic function tracer, by default, _mcount is defined as an
"empty" function, it returns directly without any more action . When
enabling it in user-space, it will jump to a real tracing
function(ftrace_caller), and do the real job for us.
Differ from the static function tracer, dynamic function tracer provides
two functions ftrace_make_call()/ftrace_make_nop() to enable/disable the
tracing of some indicated kernel functions(set_ftrace_filter).
In the -v4 version, the implementation of this support is basically the same as
X86 version does: _mcount is implemented as an empty function and ftrace_caller
is implemented as a real tracing function respectively.
But in this version, to support module tracing with the help of
-mlong-calls in arch/mips/Makefile:
MODFLAGS += -mlong-calls.
The stuff becomes a little more complex. We need to cope with two
different type of calling to _mcount.
For the kernel part, the calling to _mcount(result of "objdump -hdr
vmlinux"). is like this:
108: 03e0082d move at,ra
10c: 0c000000 jal 0 <fpcsr_pending>
10c: R_MIPS_26 _mcount
10c: R_MIPS_NONE *ABS*
10c: R_MIPS_NONE *ABS*
110: 00020021 nop
For the module with -mlong-calls, it looks like this:
c: 3c030000 lui v1,0x0
c: R_MIPS_HI16 _mcount
c: R_MIPS_NONE *ABS*
c: R_MIPS_NONE *ABS*
10: 64630000 daddiu v1,v1,0
10: R_MIPS_LO16 _mcount
10: R_MIPS_NONE *ABS*
10: R_MIPS_NONE *ABS*
14: 03e0082d move at,ra
18: 0060f809 jalr v1
In the kernel version, there is only one "_mcount" string for every
kernel function, so, we just need to match this one in mcount_regex of
scripts/recordmcount.pl, but in the module version, we need to choose
one of the two to match. Herein, I choose the first one with
"R_MIPS_HI16 _mcount".
and In the kernel verion, without module tracing support, we just need
to replace "jal _mcount" by "jal ftrace_caller" to do real tracing, and
filter the tracing of some kernel functions via replacing it by a nop
instruction.
but as we have described before, the instruction "jal ftrace_caller" only left
32bit length for the address of ftrace_caller, it will fail when calling from
the module space. so, herein, we must replace something else.
the basic idea is loading the address of ftrace_caller to v1 via changing these
two instructions:
lui v1,0x0
addiu v1,v1,0
If we want to enable the tracing, we need to replace the above instructions to:
lui v1, HI_16BIT_ftrace_caller
addiu v1, v1, LOW_16BIT_ftrace_caller
If we want to stop the tracing of the indicated kernel functions, we
just need to replace the "jalr v1" to a nop instruction. but we need to
replace two instructions and encode the above two instructions
oursevles.
Is there a simpler solution? Yes! Here it is, in this version, we put _mcount
and ftrace_caller together, which means the address of _mcount and
ftrace_caller is the same:
_mcount:
ftrace_caller:
j ftrace_stub
nop
...(do real tracing here)...
ftrace_stub:
jr ra
move ra, at
By default, the kernel functions call _mcount, and then jump to ftrace_stub and
return. and when we want to do real tracing, we just need to remove that "j
ftrace_stub", and it will run through the two "nop" instructions and then do
the real tracing job.
what about filtering job? we just need to do this:
lui v1, hi_16bit_of_mcount <--> b 1f (0x10000004)
addiu v1, v1, low_16bit_of_mcount
move at, ra
jalr v1
nop
1f: (rec->ip + 12)
In linux-mips64, there will be some local symbols, whose name are
prefixed by $L, which need to be filtered. thanks goes to Steven for
writing the mips64-specific function_regex.
In a conclusion, with RISC, things becomes easier with such a "stupid"
trick, RISC is something like K.I.S.S, and also, there are lots of
"simple" tricks in the whole ftrace support, thanks goes to Steven and
the other folks for providing such a wonderful tracing framework!

MIPS: Tracing: Add function graph tracer support for MIPS
The implementation of function graph tracer for MIPS is a little
different from X86.
in MIPS, gcc(with -pg) only transfer the caller's return address(at) and
the _mcount's return address(ra) to us.
For the kernel part without -mlong-calls:
move at, ra
jal _mcount
For the module part with -mlong-calls:
lui v1, hi16bit_of_mcount
addiu v1, v1, low16bit_of_mcount
move at, ra
jal _mcount
Without -mlong-calls,
if the function is a leaf, it will not save the return address(ra):
ffffffff80101298 <au1k_wait>:
ffffffff80101298: 67bdfff0 daddiu sp,sp,-16
ffffffff8010129c: ffbe0008 sd s8,8(sp)
ffffffff801012a0: 03a0f02d move s8,sp
ffffffff801012a4: 03e0082d move at,ra
ffffffff801012a8: 0c042930 jal ffffffff8010a4c0 <_mcount>
ffffffff801012ac: 00020021 nop
so, we can hijack it directly in _mcount, but if the function is non-leaf, the
return address is saved in the stack.
ffffffff80133030 <copy_process>:
ffffffff80133030: 67bdff50 daddiu sp,sp,-176
ffffffff80133034: ffbe00a0 sd s8,160(sp)
ffffffff80133038: 03a0f02d move s8,sp
ffffffff8013303c: ffbf00a8 sd ra,168(sp)
ffffffff80133040: ffb70098 sd s7,152(sp)
ffffffff80133044: ffb60090 sd s6,144(sp)
ffffffff80133048: ffb50088 sd s5,136(sp)
ffffffff8013304c: ffb40080 sd s4,128(sp)
ffffffff80133050: ffb30078 sd s3,120(sp)
ffffffff80133054: ffb20070 sd s2,112(sp)
ffffffff80133058: ffb10068 sd s1,104(sp)
ffffffff8013305c: ffb00060 sd s0,96(sp)
ffffffff80133060: 03e0082d move at,ra
ffffffff80133064: 0c042930 jal ffffffff8010a4c0 <_mcount>
ffffffff80133068: 00020021 nop
but we can not get the exact stack address(which saved ra) directly in
_mcount, we need to search the content of at register in the stack space
or search the "s{d,w} ra, offset(sp)" instruction in the text. 'Cause we
can not prove there is only a match in the stack space, so, we search
the text instead.
as we can see, if the first instruction above "move at, ra" is not a
store instruction, there should be a leaf function, so we hijack the at
register directly via putting &return_to_handler into it, otherwise, we
search the "s{d,w} ra, offset(sp)" instruction to get the stack offset,
and then the stack address. we use the above copy_process() as an
example, we at last find "ffbf00a8", 0xa8 is the stack offset, we plus
it with s8(fp), that is the stack address, we hijack the content via
writing the &return_to_handler in.
If with -mlong-calls, since there are two more instructions above "move
at, ra", so, we can move the pointer to the position above "lui v1,
hi16bit_of_mcount".

This option supports all of the Octeon reference boards from Cavium
|
|
|
|
Networks. It builds a kernel that dynamically determines the Octeon
|
|
|
|
CPU type and supports all known board reference implementations.
|
|
|
|
Some of the supported boards are:
|
|
|
|
EBT3000
|
|
|
|
EBH3000
|
|
|
|
EBH3100

|
|
|
|
Hikari

Please make sure to pick the right CPU type. Linux/MIPS is not
|
|
|
|
designed to be generic, i.e. Kernels compiled for R3000 CPUs will
|
|
|
|
*not* work on R4000 machines and vice versa. However, since most
|
|
|
|
of the supported machines have an R4000 (or similar) CPU, R4x00
|
|
|
|
might be a safe bet. If the resulting kernel does not work,
|
|
|
|
try to recompile with R3000.

Choose this option if you want to enable the Enhanced Virtual

Addressing (EVA) on your MIPS32 core (such as proAptiv).
|
|
|
|
One of its primary benefits is an increase in the maximum size
|
|
|
|
of lowmem (up to 3GB). If unsure, say 'N' here.

Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
|
|
|
|
require workarounds. Without workarounds the system may hang
|
|
|
|
unexpectedly. For more information please refer to the gas
|
|
|
|
-mfix-loongson2f-nop and -mfix-loongson2f-jump options.
|
|
|
|
|
|
|
|
Loongson 2F03 and later have fixed these issues and no workarounds
|
|
|
|
are needed. The workarounds have no significant side effect on them
|
|
|
|
but may decrease the performance of the system so this option should
|
|
|
|
be disabled unless the kernel is intended to be run on 2F01 or 2F02
|
|
|
|
systems.
|
|
|
|
|
|
|
|
If unsure, please say Y.

The kernel memory allocator divides physically contiguous memory

blocks into "zones", where each zone is a power of two number of

|
pages. This option selects the largest power of two that the kernel
|
|
|
|
keeps in the memory allocator. If you need to allocate very large
|
|
|
|
blocks of physically contiguous memory, then you may need to
|
|
|
|
increase this value.
|
|
|
|
|
|
|
|
This config option is actually maximum order plus one. For example,
|
|
|
|
a value of 11 means that the largest free memory block is 2^10 pages.
|
|
|
|
|

The page size is not necessarily 4KB. Keep this in mind
|

when choosing a value for this option.

Even if you say 'Y' here, the emulator will still be disabled by

kernel will support. The maximum supported value is 32 for 32-bit

kernel and 64 for 64-bit kernels; the minimum value which makes

This is purely to save memory - each supported CPU adds

approximately eight kilobytes to the kernel image. For best

power of two.

kexec is a system call that implements the ability to shutdown your

current kernel, and to start another kernel. It is like a reboot
|
2007-05-09 09:12:20 +04:00
|
|
|
but it is independent of the system firmware. And like a reboot
|
2007-01-16 17:29:11 +03:00

you can start any kernel with it, not just Linux.
|
|
|

2007-10-20 03:34:40 +04:00

The name comes from the similarity to the exec system call.

When this is enabled, the kernel will support use of 64-bit floating

point registers with binaries using the O32 ABI along with the
|
|
|
|
EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
|
|
|

32-bit MIPS systems this support is at the cost of increasing the

size and complexity of the compiled FPU emulator. Thus if you are
|
|
|

running a MIPS32 system and know that none of your userland binaries
|
|

will require 64-bit floating point, you may wish to reduce the size

of your kernel & potentially improve FP emulation performance by

saying N here.

concerning its effect upon the O32 ABI in userland are still being

worked on. In order to avoid userland becoming dependant upon current

behaviour before the details have been finalised, this option should

be considered experimental and only enabled by those working upon

said details.

Solved by changing the compat ABIs in kconfig to select MIPS32_COMPAT
directly. This also means the user no longer has to select MIPS32_COMPAT
before being able to see the ABI options.
