Cache Questions
Hello All, We're working on a driver for a PCI card, we're currently running into a problem that's symptomatic of a cache coherency problem. We have a area of memory that we manipulate and pass a physical address to our card. In other OS's (Linux, NT), before we manipulate this memory area, we mark the area as non-cachable. Are there similar operations/system calls we can use in FreeBSD? Are there any FAQ's, Docs or man-pages that explain memory usage/attributes? Thanks very much!

Re: smbfs-1.3.0 released
When is this going to be brought into -current? Boris Popov wrote: Hello, At first, I'm want to say 'thank you' for everybody who provided me with feedback on my work. So, here is a records from the HISTORY file for last two releases: 20.10.2000 1.3.0 - Network IO engine significantly reworked. Now it uses kernel threads to implement 'smbiod' process which handles network traffic for each VC. Previous model were incapable to serve large number of mount points and didn't work well with intensive IO operations performed on a different files on the same mount point. Special care was taken on better usage of MP systems. Unfortunately, kernel threads aren't supported by FreeBSD 3.X and for now it is excluded from the list of supported systems. - Reduce overhead caused by using single hash table for each mount point. 26.09.2000 1.2.8 (never released) - More SMP related bugs are fixed. - Make smbfs compatible with the Linux emulator. - smbfs now known to work with IBM LanManager (special thanks to Eugen Averin) - Fix problem with files bigger than 2GB (reported by Lee McKenna) - Please note that smbfs may not work properly with FreeBSD 3.X.

Understanding what happens on open() within the kernel
Hi, i'm currently working on understanding the FreeBSD kernel. Therefore I read the book "The design and implementation of the 4.4BSD OS". As I know that most of the things described in this book are probably no longer up to date, I think that the basics should be the same. As I would like to experiment a bit with the serial port I have a question conerning the open() call. Perhabs you could tell me if I understood the open-procedure correctly: On opening i.e. /dev/cuaa0 the kernel sees that this is a tty device. It then calls ttyopen(). Ttyopen() knows which driver is responsible by analyzing the minor device number. It calls the real open() function from the driver responsible for that device and then fills in the tty structure. Now you can change settings by using ioctl() or the termios functions. What would I have to do to get the filled in tty_structure directly, without using ioctl to get the settings of a tty? Or is there perhabs an ioctl() call to get the tty_structure? Greetings, Alex PS: Please answer directly to me as I'm not on the list.

gateway on different subnet
Summary of the problem: Can't assign cable modem gateway (10.17.56.12) to interface ed0 with assigned IP (208.59.162.242) - "network unreachable". I called RCN (my cable provider) and asked them to give me a gateway on the same subnet; they said they "don't do that". Part of solution: I set an alias for ed0 to 10.17.0.1 and it accepted the cable modem gateway as is. BUT, the packets are sent out with source address (10.17.0.1) responses to which, I suspect, gateway doesn't know how to route. Question: how can I have an alias of 10.17.0.1 and send out all packets with source address set to 208.59.162.242 (the IP that is actually assigned to the interface - not alias). Thanks for any help you can give. Marko P.S. Alternately, how can I force the system to allow a gateway that is on a different subnet (like windows allows that). Who can I turn to for help ?

Re: DMA in drivers?
"This register is used to establish the PCI address for data moving from the the Host Computer Memory to the card. It consists of a 30 bit counter with the low-order 2 bits hardwired as zeros. The address stored may be any nonzero byte length that is a multiple of 8, since 8 bytes are required to make up a DES encryption block. The Source Address Register is continually updated during the transfer process and will always be pointing to the next unwritten location." What do I need to do to get a memory address for the source and destination data for the DMA transfers? It sounds as if these memory addresses must have the last three bits zeros, will this happen automatically? Right now I am stuck on how this DMA stuff is working and any help would be appreciated. Oh yeah, I am targeting this driver for a FreeBSD 3.x system. sounds to be that it wants the buffers to be long-word aligned (multiple of 4 bytes) and not greater than 1 GB (address 0x3ffc). the source data must be null padded so that the length is a multiple of 8 bytes. other gotchas, the addresses you specified must be the PHYSICAL address, not the kernel virtual address. use the vtophys(mtr-bigbuf) routine to get the physical address. The physical page should be wired down, so it does not get paged out to swap between the time you set up the DMA and the DMA finish. be sure the data does not cross into another physical page unless the two pages are contiguous.

Re: gateway on different subnet
Hm -- how about using proxy-arp style routing? If their router has has proxy-arp support turned on, then you can set yourself (ie your own IP) as the default and will arp for _all_ addreeses of _all_ remote boxes you try to connect to. Then their router sends a response to the arp-request and your box gets an apr table entry of the router (within the local ethernet-broacast realm) and will send stuff for whatever remote IP address you have. It's not the cleanest solution, but I've used it under windows, linux and hpux to get around the foolishness of a network architecture I couldn't change... I used this at an old job where I had non-contiguous IP networks in the same ethernet-broacast domain so that all the machines would find each other on the local network, and the router handled all the off-segment connections via proxy-arp. I have NOT tried this under FreeBSD as I thankfully dont work there any more (was converted to the FreeBSD religion after I left...). Alternatively, you could use an exceptionally permissive netmask so that the local box _thought_ the other IP was in the same 'network' as yours. Pretty much both achieve the same effect of putting the remote router on the 'same network' as you. Good luck.

Re: gateway on different subnet
Hm -- how about using proxy-arp style routing? Here's what I've done in the past: 1. Have a friend out in the net ping your address 208.59.162.242 2. Run tcpdump and look for someone ARPing for you. That someone will very likely be your default gateway as seen from your site. If that router is in your subnet, set your default to it and you're done. If not, continue at the next step. 3. Pick an IP Address in your cable subnet that feels like a really good router address to you. Make something up. 208.59.162.1 perhaps? 4. Use "arp -s 208.59.162.1 xx:xx:xx:xx:xx:xx" to install an arp entry in your route table for this made-up address. That will keep you from ARPing for 208.59.162.1 and discovering the device that really owns that address. 5. Set your default gateway to 208.59.162.1.
