ALS4000 Sound Chip
I just bought a PCI sound card based on an ALS4000 chip. It seems to be sound blaster compatible (port 0x220 irq 5 drq 1). Do I have a chance to get the card working when modifying /usr/src/sys/dev/sound/isa/sbc.c in such a way that the chip will be recognized in sound blaster mode during pci bus scan? Thanks for any reply or hint!

AuDSL
Hi, I am trying to get AuDSL ( See http://www.araneus.fi/audsl/) to work under FreeBSD. One major problem is that it requires both the read and write channels of the soundcard to be mmap()-able. On 4.3-RELEASE, the following comment can be found in sys/dev/sound/pcm/dsp.c : /* XXX this is broken by line 204 of vm/device_pager.c, so force write buffer */ Is this still the case under -current? If so, is there something I can do to get this to work? regards, jacques To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message

Ahem.
First of all, Linux' file system (ext2fs) is more or less equivalent,
in terms of performance and integrity, to async ffs. This gives Linux
a big performance edge out of the box, and FreeBSD a big reliability
edge - but benchmark authors rarely care about fs integrity, as
shutting off the power during heavy disk I/O isn't generally part of
their benchmark.
well, IMVHO, it should be ;-)
Second, we tried turning write caching on ATA drives off by default,
and boy were you (the user community) pissed. Yes, turning wc off
shows you just how crappy those non-tagged-queueing 4000 RPM ATA
drives you picked up at Fry's for some pocket change are. So we
turned it back on. If you're not happy with that, put 'hw.ata.wc=0'
in your /boot/loader.conf and they'll be off after the next reboot.
Or get real disks.
that's one for the handbook, eh? imagine:
Q: i got problem {...}, it seems to depend on (ATA|IDE|disk|drive|...)

it would be a nice thing[tm] to have such stuff in the docs.

Changes to the /etc/rc* boot system
[Please follow up on this discussion in -arch] Gang, Several people are leaping into the fray with enthusiasm for this project all of a sudden, which is a good thing. However, I'm a little concerned that it's not getting enough of a big picture view. What may seem like lack of progress at this point is actually an effort to do several things before we proceed. A) Examine what we have (most of us understand that pretty well) B) Figure out what we need (in progress, nowhere near done yet) C) Take a hard look at NetBSD's code to determine if it meets our needs D) If we decide C) is yes, figure out how to port/improve it C is pretty much a given in most people's minds at this point. Whether that is a good thing or not I'm not sure, but let's take that as a starting point for now. Given that there will be no small effort in porting their code to our system, and given that we already have the cooperation of one of the NetBSD developers to help with D), I would like to suggest that people bend their efforts away from trying to be the first one to get some code into our tree and onto some of the more general topics. Unfortunately, Luke from NetBSD is both very busy, and busier still until after Usenix. He's asked us to hold off on this till then, and I think that's reasonable. What I'd really like to focus on at this point are three questions. 1. What needs to be done differently on our system than theirs? 2. What would we like to improve on in their current system? 3. How can we take the current code and make it easier to maintain across both platforms? If we can have some good answers to those questions ready for after usenix, then we can start off the What would the NetBSD developers do differently knowing what they know now? conversation with some intelligent points of our own.

No, what I am essentially saying is that anyone who has a need to run something that sophisticated had better have some clue as to the platform he is using or he has no business running it. Even if the platform were tuned for the so-called 'large' installation, if the administrator doesn't know much about his most critical server the poor company that hired him is going to have a hellofalot more to worry about then the server not being magically tuned! I agree with that. By the way, is not it customary for the benchmarks run by magazines to consult the manufacturers if the testers are not able to configure the system by themselves ? I don't remember these guys asking questions on -hackers. And I will point out that NT is hardly optimized for 'large servers'. What, are you nuts? It took BEST Internet months... that's MONTHS... hundreds of man-hours to optimize an NT box to handle more then a handful of simultanious frontpage users and even then it couldn't even approach what one of our FreeBSD boxes was doing. It took HiWay Are you talking about Hotmail ? My understanding about it was that they run 5000 small servers, exactly the case when even an out-of-the-box FreeBSD will shine, not even speaking about a tuned one. Technologies another few months, *with* microsoft's help, to get their dedicated NT web server platform to even come close to what their SGI boxes were throwing out. It was a disaster all around. Optimized out of the box? I don't think so. An NT or W2K box might run on a 16-way system, and it may appear all rosy in contrived benchmarks, 32-way I think. At least that's what a full-blown Unisys ES7000 machine has and MS claims to support it. but in the real world it doesn't stack up. At least we (FreeBSD and Linux) don't pretend that our systems scale well to 16-way boxes... only Solaris (and now defunct SGI hardware) can make that claim. NT And Dynix and AIX and HP-UX and UnixWare. and W2K on a 16-way box would be a huge waste of money. Well, UnixWare runs circles around it on the same box. However FreeBSD does not scale well beyond 2 CPUs yet. Windows admins have odd ideas about what constitutes 'large'. Their idea of large is a rack full of windows boxes serving a few hundred active users, or maybe a colo-full of boxes serving a few thousand, or perhaps a bunch of expensive 4-way or 16-way cpu boxes to server X users. Nope, these SMP boxes are usually used for the database servers. The difficulty with the databases is that (unlike web servers or pop/smtp servers or other such stuff) you can't easily divide the job to an arbitrary number of small machines with a simple load balancer. The efficiency of interlocking and data exchange requires one big machine with large memory and many peripheral buses. Our idea of large (in this case defined by Terry or Paul Saab) is one FreeBSD box handling tens of thousands to a hundred thousand TCP connections, and a rack full of machine serving millions. Windows people conveniently forget the amount of work it takes to get an NT or W2K box operating, the amount of work it takes to upgrade one, and the amount of work it takes to fix one when something breaks. They don't fix, they reinstall (not that it reduces the amount of time but the contrariwise). -SB To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message
Re: Article: Network performance by OS
It's a lot faster on writes with softupdates enabled. FreeBSD will also have journaling filesystems soon. Either way, this was not a very good benchmark.

File systems tests (EXT2 for Linux, UFS for FreeBSD and Solaris, and NTFS for Windows 2000) were performed by creating writing, and reading 10,000 files in the same directory, increasing the file size from 4K to 128K. Tests of various network applications based on number of simultaneous connections, process-based vs. thread-based, and sync vs. async connection handling were also performed.

The press release that I remember from last year was a Compaq one (or was it SCO), but not Microsoft. Definitely not SCO. Though SCO's Great Networking Achievement of year 2000 was an implementation of in-kernel sockets (as opposed to the user-level library over TLI) so there is a chance that you had it confused with this. -SB To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message

Re: max kernel memory
On Mon, 18 Jun 2001, Matt Dillon wrote: DG changed KERNBASE a while back to reserve a gigabyte of VM for the kernel. This should be sufficient on a 4G machine but it depends where your resources are going. If your server's resources are user-process centric then you don't need to change KERNBASE. If your server's resources are network-mbuf centric then you may have to give the kernel Most of the resources will go into mbufs, clusters, socket structures, PCBs, etc. I mean, supporting a million TCP/IP connections is the primary goal. If setting aside more memory for kernel usage doesn't work out, then I guess I'll have to have some user-level dummy processes that just hold memory for me, and pass it on whenever required. But memory bandwidth is still going to be an issue. (not to forget user-kernel switches, user-kernel copy, etc.). more KVM (e.g. like 2GB instead of 1GB... 0x8000 instead of 0xC000). But be careful. The more KVM reserved for the kernel, the less VM is available for user processes to allocate and mmap. I'm sure people who run 4G machines can give you better information, I've never run anything larger then 2G myself, though expect down the line I'll begin needing 4G machines to support larger databases. An associated question: along with this, changing the kernel to use only PDEs should be better for TLB performance. Mapping 4Mb at a time would definitely be much better than 4k. I'm talking of having the entire kernel (at least the code) find mappings in the TLB, and keeping 4Mb mappings might just do the trick. I did see pmap_kmem_choose() being called pretty early in pmap_bootstrap(), but it looks like it's doing that for a single page; what I want is to have 4M mappings for all pages in the system.

The kernel maps itself using 4MB pages but normal 4K pte's are used for kernel allocations. What you are doing sounds interesting, and supporting lots of connections certainly could require a great deal of kernel memory, but it all depends on what you are *doing* with those connections. If you are acting as a router you don't need much KVM. If you are acting as a diskless (non-caching) web or tcp proxy then you do need KVM. If you are serving web pages and the pages do not fit entirely in ram, you are likely to hit disk I/O limitations long before you hit network/cpu limitations.
