binary file within a shell script

Hi there, I would like to use one exec file from a shellscript but I would like it to be incorporated in the same file, like Nvidia do for its FreeBSD drivers. How can I do this in a convenient way ? Mathieu ___ freebsd-hackers@freebsd.org mailing list

Re: binary file within a shell script

It's not exactly what you are looking for: But you could take a look at shar(1). I don't even know for sure whether it can archive binaries. shar gives you a shellscript, to which you could prefix your own script, and when you run it, it'll extract the incorporated file, and you can exec it :)

vm_map_insert fails, vm_map-max_offset==0?

Hi, is it possible to insert a new map entry to a process vm_map from a kernel module? I've tried to use vm_map_insert, vm_map_fixed, vm_map_findspace, but they all fail as the vm_map-max_offset is zero (0). I have looked at vm_mmap etc. but I don't get a clue what I'm doing wrong... BR, Teemu

SW_PREEMPT and cpu runq

Hi, When a thread is being switched out and it is being preempted (e.g. time quantum expires), why does sched_switch hold it on the current cpu? i.e. why does the code see that it was preempted and put it back on the same queue? In other cases it looks to see if it can be migrated and the

RE: SW_PREEMPT and cpu runq

I guess two places. 1. maybe_preempt() - I've decided to preempt a thread on a cpu and the outgoing thread is held (SW_PREEMPT) on the same cpu. 2. timer expires and thread is out of its slice (ULE), in this case I remove the load and re-add it back to the same (current) cpu. Sorry Julian, yes

RE: SW_PREEMPT and cpu runq

Oh, I find this happens only in ULE -- during sched_switch(), it sets KEF_HOLD and then calls setrunqueue(). This ensures that the thread does not migrate on preemptions. Ravi -Original Message- From: Murty, Ravi Sent: Thursday, May 08, 2008 3:48 PM To: 'Julian Elischer' Cc:
