IPX performance

Hi! I use old mars_nwe but have problems with its performance. It works really poor. I would like to check if it's just IPX subsystem problem (== kernel problem?) or just poor mars_nwe code. Unfortunately I can't find any IPX benchmarks and I have no real Netware servers to compare. What can I do

Re: how long does a single context switch take ?

Thank you for this elaborate clarification. I was indeed interested in #3, although #1 and #2 are also interesting. from what i recall, la_ctx measures #3. it does so by creating a ring of unix processs connected with pipe, and then passes a token around, each processes does some work polluting

current macro in late kernel version?

Hi, I noticed that the value of current macro has changed in the newer kernel version (from 2.6.20?). It seems that now the task_struct structure that points to the current process is now put in the FS segment. That means from address range 0 upwards, we have the current structure. Could anybody

Re: tasklet_action() failure

Very good. Now I'm trying to figure out why this tasklet_action() code path ends up calling BUG(). This is a very intermittent problem and seemingly impossible to reproduce. 404 if(!test_and_clear_bit(TASKLET_STATE_SCHED, t-state)) 405 BUG(); It's obvious that 404 will result in

RE: IPX performance

Hi, Can any one kindly tell me what Software Interrupt exactly means? Also, how is it different from the Hardware Interrupt? Regards, Aravind. Dovie'andi se tovya sagain -Mat Cauthon (WoT). -- To unsubscribe from this list: send an email with unsubscribe kernelnewbies to [EMAIL

RE: IPX performance

Hi Aravind, It pays to be precise when talking about these terms. Software Interrupt is a bit of a misnomer because software never really interrupts a cpu, it does not alter the sequence of instructions. Maybe what you mean is; what is the difference between and interrupt and an exception?

__divdf3 and friends undefined

Hi. I'm currently porting a framework developped by my research group for supporting multiple interfaces/channels under linux 2.6. I'm almost done, but I get some warnings when compiling: WARNING: __divdf3 [/home/cf/netx-2.6/bonding/bonding.ko] undefined! WARNING: __floatunsidf

Re: __divdf3 and friends undefined

I finally found the bug: somewhere in the code there was a macro like (5.5 * 100) the preprocessor expands this. as a floating point. And floating point is not allowed in the kernel (well, it needs math-emu, which are the symbols that were missing). Man, it took me 1 day to figure that out...

Re: tasklet_action() failure

TASKLET_STATE_SCHED is set when tasklet is scheduled using tasklet_schedule or tasklet_hi_schedule and clear only when the tasklet starts its execution. Are you using some customized kernel or stock kernel? I believe there should not be this bug in stock kernel. - Meraj Tony Mouawad [EMAIL
