audiols integrated

I've integrated the audiols driver into build 124 (actually I think this might have been the first push into snv124 -- thanks to jmcp for approving it so quickly!) From my HEADS UP message:

The push of CR 6875005 introduces support for audio for Creative Audigy LS devices. If you have such a device, you can now enjoy audio playback and record support using your audio device.

Devices supported are identifiable by the PCI id pci1102,7. Known compatible devices include Creative Audigy LS, Creative Audigy SE, Creative Sound Blaster Live! 24-bit, and Creative X-Fi Extreme Audio.

This driver includes 5.1 surround sound support.

Bugs for this driver should be filed in bugster using solaris/audio/driver-audiols.

Assorted audio cards needed

4Front has provided some drivers for me, which are nearly complete, but which need some attention. However, I am lacking hardware for a number of these drivers, and have not had good success finding many of them on eBay. If you have access to spare cards to donate, or even sell, please let me know.

Here's a short list of cards:
  1. CS4281 (I tried to purchase one of these, but they shipped me an ESS Solo-1 instead!)
  2. CS4280
  3. FM-801 (ideally a 6-channel variant)
  4. CMI 8768
  5. CMI 8738 (6-channel, or even 8-channel varient)
  6. CMI 8788 (these are high end cards, they can be purchased, but right now I'd have to fund this myself if I want to work on the driver -- its not a priority. This is typically the Asus Xonar card.)
There are probably other interesting audio cards as well.

It should be said that the recent work on some of these cards is occurring on my own time, since I have higher priorities (not soundcard related) during my day job, which is why its hard for me to ask Sun to provide funding for these things. (In the case of cs4281 and fm-801 cards, I've found them hard to even locate. Witness my failed attempt to purchase a CS4281. Taiwanese vendors consider these interchangeable parts. :-(

audiols works nicely on sparc

Just for giggles, I went ahead and tested it:


audiols/fortyfive> pfexec audiotest -5 /dev/dsp1
Sound subsystem and version: SunOS Audio 4.0 (0x00040003)
Platform: SunOS 5.11 snv_119 sun4u

*** Scanning sound adapter #2 ***
/dev/sound/audiols:0dsp (audio engine 1): audiols#0
- Performing audio playback test...
<left> ................OK
<right> ...............OK
<stereo> ..............OK
<left rear> ...........OK
<right rear> ..........OK
<center> ..............OK
<lfe> .................SKIPPED
<5.0 surround> ........OK
<measured sample rate 47952.00 Hz (-0.10%)>

*** All tests completed OK ***
audiols/fortyfive> uname -a
SunOS fortyfive 5.11 snv_119 sun4u sparc SUNW,A70


I'll go ahead and include SPARC support after all. Maybe someone with an Ultra 45 or 25 will like this.

AudigyLS Boomer Driver Posted

I've posted test binaries for the AudigyLS driver for Boomer systems. There is also a webrev posted. These are test binaries only! Use at your OWN RISK!

If you do use them, please let me know how it goes.

Thanks!

Surround Sound on SPARC?

I'm about ready to integrate the Audigy LS audio driver, which is a PCI add-in card that is capable of 5.1 surround sound. (I've been working on it in the "off" hours, as I currently have other higher priority projects that I'm working on while doing work on Sun's nickel; this explains why it has taken so long.)

I have one quick question: does anyone really want to have this work on SPARC systems? The only tangible advantages I could see for this are:
  • If your internal audio device is busted, there is another alternative.
  • If you have some compelling reason to want surround sound support on your SPARC system.
Right now because the effort to qualify and integrate takes a while, and because I hate the idea of integrating bloatware that nobody is going to use, I am not planning on integrating SPARC support for this driver. However, if at least one or two people speak up and tell me that this is something that they want, then I'm much more likely to take the time to do the work. (The driver should Just Work on SPARC, its mostly a matter of running the tests, which take a few hours.)

So, if this is something you want, let me know!

Community Contributions

I've recently (in the past week) integrated a small improvement from Roland ( so kernel code can use C99 booleans (supposedly there are performance gains for using this relative to boolean_t), and a major overhaul and conversion to GLDv3 for the legacy "dnet" driver from Steve Stallion.

I would like to thank both contributors for their patience. Neither of these was a particularly trivial integration. Steve in particular worked on this integration for quite a long time, due largely to the high cost of getting such a crufty driver to pass through NICDRV.

Fun With Rocketry

Well, today I finally got a model rocket set ... been wanting one since I was about 8 years old. Now that my son is that old, I finally can justify it. :-) The kids and I went to a park and set up 4 launches (well really 3, more on that later) of a single stage Estes rocket (A3-4T engines, IIRC ... basically about the smallest engines typically sold.) Total cost was about $30.

The kids really enjoyed it, and I can tell by the questions Timothy is asking that he's thinking about implementation -- he's definitely got the budding mind of an engineer. (How does the ejection charge work? What's the purpose of the recovery streamer? How do multistage rockets work? Etc.)

We did have one minor mishap, on our first launch attempt. Turns out that the rocket had wedged against the small plastic keeper, creating just enough friction to turn our launch into a static test. The engine burned a small hole, about 50 mm in diameter, right through the aluminum guard plate on the launcher; an amazing testament to the power of even these relatively tiny rocket engines. Needless to say, it definitely helped demonstrate the importance of all the safety measures I was stressing. :-)

The next three flights went off without a hitch. The product documentation says "up to 350 feet", but I think the peak heights looked higher than that.

For his 9th birthday in November, I'll probably invest in some other more sophisticated models. Its cool to be a kid again, but its even more cool to see your kid's eyes light up; who knew learning could be such fun!

Test Marvell Yukon 2 Ethernet Driver

I've posted a test version of my "yge" driver (Marvell Yukon Gigabit Ethernet, but it also supports some 100Mbps devices) up on OpenSolaris.org. Get it here -- get the file called yge-test.tar.gz.

There is a webrev posted too, if you want to beat your head against the wall.

If you do test this, be aware that many possible PCI ids are not in the installer file. If you want to test more, please do so (at your own risk). If you find that other devices either do work, or do not, please let me know -- send mail to garrett.damore at sun dot com.

Thanks, and enjoy! (I'm hoping to get this driver integrated into SNV 123.)

A Push A Long Time In Coming

I just pushed the changes associated with PSARC 2005/425, which is basically the removal of the script wrappers /usr/ucb/cc, /usr/ucb/lint, and /usr/ucb/ld. The fix will be in b122 of ON.

This is a good thing for people who build free software bits on OpenSolaris. For a long time, there have been complaints that /usr/ucb on your PATH was particularly toxic (some would say it was toxic anyway, but that's a different matter) -- autoconf scripts were frequently confounded by /usr/ucb/cc, which has done nothing more than generate a useless error message for most people.

So, /usr/ucb/ on your path, while not recommended, is at least no longer particularly toxic.

audiovia97 not as rare as I thought

So I was cleaning out my office.... (no jokes from the peanut gallery please!)

I was completely surprised to find that out of 5 old machines I was about to retire to the recycler, no fewer than three of them -- from totally different manufacturers -- one of them was Compaq Presario -- had integrated Via82c686 audio (which is supported by audiovia97.)

So if you've still got old Celeron's or PIII class systems around, there's a pretty good chance that you can get audio in OpenSolaris on them now.

Another way you know you're getting old...

When someone on facebook is confused and mixes up your H.S. graduation date with their birthday.

People born back when I was graduating high school are now graduates themselves.

Getting old sucks. But its better than the alternative.

ohloh.net

I found an interesting site; it tracks commits by developer, and potentially ranks them, using a "kudos" system. There's also a way to give and to receive "kudos". It also has some source code analysis for projects, though I don't necessarily agree with all that it does. (A project that is 50% comments is not inherently better than a project that is 10% lines... you can't judge code quality or readability or structure based on comments.)

Anyway, I just joined and made it aware of who I am... I have a "kudo" rank of 7. If anyone else here is using this service, I'd be curious to know about it. My account information is here.
