Mini-HOWTO for using the earlyprintk=dbgp boot option with a
|
||||
USB2 Debug port key and a debug cable, on x86 systems.
|
||||
|
||||
You need two computers, the 'USB debug key' special gadget and
|
||||
and two USB cables, connected like this:
|
||||
|
||||
[host/target] <-------> [USB debug key] <-------> [client/console]
|
||||
|
||||
1. There are three specific hardware requirements:
|
||||
|
||||
a.) Host/target system needs to have USB debug port capability.
|
||||
|
||||
You can check this capability by looking at a 'Debug port' bit in
|
||||
the lspci -vvv output:
|
||||
|
||||
# lspci -vvv
|
||||

|
||||
Kernel driver in use: ehci_hcd
|
||||
Kernel modules: ehci-hcd
|
||||
...
|
||||
|
||||
( If your system does not list a debug port capability then you probably
|
||||
wont be able to use the USB debug key. )
|
||||
|
||||
b.) You also need a Netchip USB debug cable/key:
|
||||
|
||||
http://www.plxtech.com/products/NET2000/NET20DC/default.asp
|
||||
|
||||
This is a small blue plastic connector with two USB connections,
|
||||
it draws power from its USB connections.
|
||||
|
||||
c.) Thirdly, you need a second client/console system with a regular USB port.
|
||||
|
||||
2. Software requirements:
|
||||
|
||||
a.) On the host/target system:
|
||||
|
||||
You need to enable the following kernel config option:
|
||||
|
||||
CONFIG_EARLY_PRINTK_DBGP=y
|
||||
|
||||
And you need to add the boot command line: "earlyprintk=dbgp".
|
||||
(If you are using Grub, append it to the 'kernel' line in
|
||||
/etc/grub.conf)
|
||||
|
||||
NOTE: normally earlyprintk console gets turned off once the
|
||||
regular console is alive - use "earlyprintk=dbgp,keep" to keep
|
||||
this channel open beyond early bootup. This can be useful for
|
||||
debugging crashes under Xorg, etc.
|
||||
|
||||
b.) On the client/console system:
|
||||
|
||||
You should enable the following kernel config option:
|
||||
|
||||
CONFIG_USB_SERIAL_DEBUG=y
|
||||
|
||||
On the next bootup with the modified kernel you should
|
||||
get a /dev/ttyUSBx device(s).
|
||||
|
||||
Now this channel of kernel messages is ready to be used: start
|
||||
your favorite terminal emulator (minicom, etc.) and set
|
||||
it up to use /dev/ttyUSB0 - or use a raw 'cat /dev/ttyUSBx' to
|
||||
see the raw output.
|
||||
|
||||
c.) On Nvidia Southbridge based systems: the kernel will try to probe
|
||||
and find out which port has debug device connected.
|
||||
|
||||
3. Testing that it works fine:
|
||||
|
||||
You can test the output by using earlyprintk=dbgp,keep and provoking
|
||||
kernel messages on the host/target system. You can provoke a harmless
|
||||
kernel message by for example doing:
|
||||
|
||||
echo h > /proc/sysrq-trigger
|
||||
|
||||
On the host/target system you should see this help line in "dmesg" output:
|
||||
|
||||
SysRq : HELP : loglevel(0-9) reBoot Crashdump terminate-all-tasks(E) memory-full-oom-kill(F) kill-all-tasks(I) saK show-backtrace-all-active-cpus(L) show-memory-usage(M) nice-all-RT-tasks(N) powerOff show-registers(P) show-all-timers(Q) unRaw Sync show-task-states(T) Unmount show-blocked-tasks(W) dump-ftrace-buffer(Z)
|
||||
|
||||
On the client/console system do:
|
||||
|
||||
cat /dev/ttyUSB0
|
||||
|
||||
And you should see the help line above displayed shortly after you've
|
||||
provoked it on the host system.
|
||||
|
||||
If it does not work then please ask about it on the linux-kernel@vger.kernel.org
|
||||
mailing list or contact the x86 maintainers.

/*
|
||||
* Some macros to handle stack frames in assembly.
|
||||
|
||||
x86 function call convention, 64-bit:
|
||||
-------------------------------------
|
||||
arguments | callee-saved | extra caller-saved | return
|
||||
[callee-clobbered] | | [callee-clobbered] |
|
||||
---------------------------------------------------------------------------
|
||||
rdi rsi rdx rcx r8-9 | rbx rbp [*] r12-15 | r10-11 | rax, rdx [**]
|
||||
|
||||
( rsp is obviously invariant across normal function calls. (gcc can 'merge'
|
||||
functions when it sees tail-call optimization possibilities) rflags is
|
||||
clobbered. Leftover arguments are passed over the stack frame.)
|
||||
|
||||
[*] In the frame-pointers case rbp is fixed to the stack frame.
|
||||
|
||||
[**] for struct return values wider than 64 bits the return convention is a
|
||||
bit more complex: up to 128 bits width we return small structures
|
||||
straight in rax, rdx. For structures larger than that (3 words or
|
||||
larger) the caller puts a pointer to an on-stack return struct
|
||||
[allocated in the caller's stack frame] into the first argument - i.e.
|
||||
into rdi. All other arguments shift up by one in this case.
|
||||
Fortunately this case is rare in the kernel.
|
||||
|
||||
For 32-bit we have the following conventions - kernel is built with
|
||||
-mregparm=3 and -freg-struct-return:
|
||||
|
||||
x86 function calling convention, 32-bit:
|
||||
----------------------------------------
|
||||
arguments | callee-saved | extra caller-saved | return
|
||||
[callee-clobbered] | | [callee-clobbered] |
|
||||
-------------------------------------------------------------------------
|
||||
eax edx ecx | ebx edi esi ebp [*] | <none> | eax, edx [**]
|
||||
|
||||
( here too esp is obviously invariant across normal function calls. eflags
|
||||
is clobbered. Leftover arguments are passed over the stack frame. )
|
||||
|
||||
[*] In the frame-pointers case ebp is fixed to the stack frame.
|
||||
|
||||
[**] We build with -freg-struct-return, which on 32-bit means similar
|
||||
semantics as on 64-bit: edx can be used for a second return value
|
||||
(i.e. covering integer and structure sizes up to 64 bits) - after that
|
||||
it gets more complex and more expensive: 3-word or larger struct returns
|
||||
get done in the caller's frame and the pointer to the return struct goes
|
||||
into regparm0, i.e. eax - the other arguments shift up and the
|
||||
function's register parameters degenerate to regparm=2 in essence.
