Hi all
I fail to use bpha command(kdb v4.4) on SLES9 SP1, ia32
platform. Steps to duplicate:
1.insmod testkdb.ko
2.Enter kdb
3.bpha mydata datar (I will access "mydata" in the
module_exit function)
4.g
5.rmmod testkdb
I cannot enter kdb after item5 but it is supposed to do so. I
have tried setting h/w breakpoint on a function which will be called in
module_exit but still unable to enter kdb.
It is certain that there is h/w debug register on ia32 h/w and
there does be the support for h/w breakpoint in kdb for such platform.
Then, the issue attribute to the OS cannot support h/w breakpoint
handler. Right?
Thanx.
