Re: No interrupts coming to device driver.
Warner, Unfortunately my BIOS do not allow IRQ reservation for ISA devices. But in I noticed Interrupt Mode menu with PIC/APIC options. This pushed me to go through another round of tests. First with PIC mode and back again with APIC but now with device apic added to kernel config. After few attempts to use different IRQs I finally got interrupts on IRQ9. Well. This is good and I can move forward with driver. Though I still confused the way it done. I will be really appreciated if some good will explain me what is behind all this woodoo I did. Is it necessary to have device apic today? And still what is the nature of those ?lost in hardware? interrupts? BTW. Here is a quote from dmesg which may be connected to the case. ACPI APIC Table: ASUS P4SQ ioapic0 Version 8.0 irqs 0-23 on motherboard acpi0: Overriding SCI Interrupt from IRQ 9 to IRQ 20 Another bits of info. Windows automagically assigns IRQ7 to device and works fine. But I can not use IRQ7 on FreeBSD even with device apic in kernel. I do have hardware which is not in use ATM (PCI TV card). But I do not have any driver installed on Windows too. So if this is the case Windows somehow makes better guess of what driver can use. Anyway thanks everyone who tried to help! All the best, Alexander. M.

Set it to trigger on an edge (either falling if the signal is high or rising if the signal is low, usually it is high). Make sure that the IRQ that you are using is not shared with anything else, even hardware you aren't using. That's forbidden in the ISA world (although some hacks exist to do interrupt sharing with two devices on the ISA bus, (a) almost nobody does them and (b) they don't work when sharing with pci). Make sure that the IRQ is set in the BIOS as Legacy/ISA rather than ISAPNP/PCI (or some variants of those phrases). See if there's a way to force an interrupt on the chip by writing to a register of some sort. It doesn't matter if you are going to use this, but it will be good for testing. It almost certainly isn't an unacknowledged interrupt (unless it is left over from before your chip reset). In my experience, those cause vmstat of 1. It might be worth checking the chip initialization sequence to make sure that you clear any possible interrupts AFTER you've done the bus_setup_inter() call to register your interrupt handler. That's all I can think of at the moment, but it should keep you busy for a few hours :-) Warner ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED] ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: UFS2 max limits?
Joseph Koshy wrote this message on Sat, Nov 12, 2005 at 11:05 +0530: The Wikipedia page referenced below says that UFS2 supports a filesystem size of 2^80 Bytes (1YiB) with the limit on a given file being 2^55 bytes (32 PiB). Those sound correct, as UFS2 uses 64bit frag addresses, which when combined with a frag size of 16 (for 65536 bytes per frag) gives you 2^80 for total file system size as for the file size, The approximate max can be calculated by (blocksize / sizeof(ufs2_daddr_t)) ^ 3 * blocksize the real max would add in addition: (blocksize / sizeof(ufs2_daddr_t)) ^ 2 * blocksize + (blocksize / sizeof(ufs2_daddr_t)) * blocksize + 9 * blocksize so, with a blocksize of 65536, and ufs2_daddr_t's size being 8 bytes, you end up with: (2^16 / 2^3) ^ 3 * 2^16 (2^13)^3 * 2^16 2^(13*3) * 2^16 2^39 * 2^16 2^(39 + 16) 2^55 but if you add the additional blocks, you'll end up with larger, but not enough to go to 2^56 for file sizes... Are these numbers correct? I somehow remember the limits as being much lower (of the order of 16TB or so). You might be thinking of UFS1... Now there is a funny thing that I found out about UFS2 and UFS1... UFS1 supports larger file sizes (not file system sizes) due to the fact that the ufs_daddr_t is smaller (32bits), means it can get more out of the indirect blocks than UFS2 can... UFS1 can have files of 2^58 compared to UFS2's 2^55... -- John-Mark Gurney Voice: +1 415 225 5579 All that I will do, has been done, All that I have, has not. ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

This could also be something related to permissions on the .ssh directory, but you cleared that out of the way if i understand the rest of this thread correctly. I remember having this problem once, but can't remember right now what i did to solve it.. I usually compile openssh from source anyway, so you might try that. If that works, it would probably be interesting to see what is the difference between your own hand-rolled openssh and the one that came with your world. Just remembered something else: do you jexec into the jail, or do you do a proper logon (eg. ssh into the jail). I think that if you jexec into the jail and then try to ssh, you might have a problem because you aren't really logged in to the jail and thus have no (psuedo) tty associated with your session..

Help: Asus P5WD2 mobo and ITE IDE controller problem
Hi all, I have had a system configured using this mobo and have hit a showstopper. The HDD (a seagate 330GB IDE) have been connected to the ITE IDE controller while the DVDrom has been connected to the primary IDE controller. It seems that the ITE device is a RAID controller, and the BIOS and the 5.4 FreeBSD installer dont see the HDD at all. Which is not very useful! The mobo has a SATA port as well, and the question is Does 5.4 support SATA drives for install? I think I can tell the BIOS to make a SATA drive 'look like' an IDE drive. (sent to hackers also for this followup question) As a followup - Does anyone know of any support re the ITE device?

I remember noticing crap fdc performance (without larger block sizes) on my dual PPro a little while back. Hmm, I think this is not the case as interrupt handler on fdc was registered with FAST handler. In addition, the handler just invokes wakeup(9), without any lock operations, to wake up kernel floppy worker thread.
