Debugging KLD's
Hi I am using the following method to debug a KLD on 4.1 using gdb remote debugging: - Add makeoptions DEBUG=-g to the kernel config - Compile the KLD with -ggdb - Use objdump -h to get the offset of .text in the KLD. - Add this value to the value reported by kldstat and use this as offset for the gdb add-symbol-file command. The problem is that variable values reported by gdb seems to be total garbage. If I add explicit printf's in the C code, the value printed on the console is correct but the values given by gdb are totally different. Everything else seems to be working - I can do a break and the breakpoint will be set correctly. Any help will be greatly appreciated. jacques __ Do You Yahoo!? Thousands of Stores.

New mergemaster behavior - comparing CVS $Id too
Is there a way to make mergemaster revert to its old behavior - only comparing $FreeBSD tags on files which have those? I keep some of my /etc files in a CVS repository of my own, and in the last mergemaster runs it detects that the file in /etc has an $Id, while the file in /var/tmp/temproot does not, and reports a difference. (Well, yes, I guess I could remove the $Id tags from my own files, but.. is there another way? :) G'luck, Peter PS. And yes, I know RELENG_4 is frozen now, but.. still.. :) -- I am not the subject of this sentence.

Help writing a screen saver module
Hi all
I am trying to write a screen saver module that, when it kicks in, will
switch to the first console, and then, if a key is pressed, will switch
back to the one that was previously active. The idea is that the first
console has something useful running on it, typically a tail -f of the
logs.
The code that I have at the moment is based on other simple saver
modules, and the VT_ACTIVATE ioctl code in syscons.c. However, it just
causes a reboot. This isn't a very important piece of code, but before I
give up on trying to get it to work, I thought I'd throw it out here and
see if anyone has any ideas.
Here are the two externally visible routines I've added to syscons.c:
--
extern int ActivateConsole(int n);
extern int GetActiveConsole(void);
int ActivateConsole(int n)
{
int s = spltty();
sc_clean_up(cur_console);
splx(s);
return switch_scr(cur_console, n);
}
int GetActiveConsole(void)
{
return get_scr_num();
}
--
Here is the module code:
--
#include
#include
#include
#include
#include
#include
#include
#include
static int last_active, blanked;
extern int ActivateConsole(int);
extern int GetActiveConsole();
static int
switch_saver(video_adapter_t *adp, int blank)
{
if (adp->va_info.vi_flags & V_INFO_GRAPHICS)
return EAGAIN;
if (blank) {
if (!blanked) {
blanked = 1;
last_active = GetActiveConsole();
ActivateConsole(0);
}
} else {
if (blanked) {
blanked = 0;
ActivateConsole(last_active);
}
}
return 0;
}
static int
switch_init(video_adapter_t *adp)
{
(void)adp;
last_active = blanked = 0;
return 0;
}
static int
switch_term(video_adapter_t *adp)
{
(void)adp;
return 0;
}
static scrn_saver_t switch_module = {
"switch_saver", switch_init, switch_term, switch_saver, NULL,
};
SAVER_MODULE(switch_saver, switch_module);

system call and SYSCALL macro
Hi:
I am trying to implement a system call. I used the syscalls.master already.
I know I have to modify libc, but this requires makeworld and all the
binaries must be compiled again. If I don't want to modify libc, I know I
have to use the SYSCALL macro or something like that. But I don't know how
to use it. Also, I tried the syscall() function but are not getting good
results.
I just try to add a simple system call for testing:
int my_call(int x, int y) {
return (x + y);
}
In my user program:
int main(int argc, char ** argv) {
int x = 3;
int y = 8;
int z = 0;
z = syscall(SYS_my_call, x, y);
printf("%i + %i = %i\n", x, y, z);
return 0;
}
But it prints:
3 + 8 = -1
Can you give me some idea what I did wrong and what I should do? Also, can
you tell me how to use the SYSCALL macro because I am not familiar with
macros at all? Thanks in advance.
Thanks.
Ray,

"iowait" CPU state
I've been using Solaris a lot lately, and I've noticed that in e.g. top's output, it has a distinct CPU state called "iowait", which seems to be a pretty good indicator of how I/O-bound a system is. Is there any reason that FreeBSD doesn't have such a state? "iostat" also seems a lot less informative than Sun's.

How do you determine that a machine/service is "failing"? Have you considered that the distributed nodes might be very far away from each other, even across the globe? Lag time can lead to daemon falsely thinking that a node is down. Example: condition, Cross pacific link being slow Node A,B in Lake Tahoe, USA. Node C,D in Maldive Islands, South Pacific Node C and D have gigabit LAN between each other, and so does A and B Lake Tahoe Pacific Ocean Maldive Islands (A+B) <---connected via T1---> (C+D) Upon lag and/or service requests to (C+D) in India, while the T1 is slow, (C+D) should take over. Upon service request in America, B is down, C+D still alive, A is under high load, no matter how light the load of C+D, the service request should be routed to A. bla bla bla. (I want to buy houses in these two places one day... 8-P ) Reading your code, I don't think broadcasting over all interfaces is a good idea. A safer way would be requiring two physical interfaces on all nodes, building two seperate physical networks. The nodes communicate information on one network, and do the actual "work" on the other, more powerful, network. The daemons on the nodes should broadcast over these two interfaces. In addition, a comparison between the connectivity of the two physical networks can provide lots of valuable info. There is another bad thing about broadcasting over all interfaces, several types of attacks can be made: A. spoofing node packets, making controlling daemon believe some machinese are down. B. network internal information acquired by people that shouldn't have them. A great thing to do with this code would be using kqueue. | - Application failover. | - Applications can be assigned to two or many nodes in the | cluster.

Have a look at systat(1). It presents the activity on your system nicely, breaking it down into several descriptive categories which are documented in the man page. Try this: $ systat -io Hope that helps, -brian -- Brian O'Shea [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
