Is anybody else currently using the ethervgbe driver? I'm had some
problems with it which don't seem to be caused by my hardware.
After receiving 256 packets I was getting:
panic: freeb: ref -1; caller pc 0xf01b1754

Turns out calling freeb was messing th
I'm porting PROJ4.3.3 (the cleanest version of proj I could find), and
it's a little ugly.
One thing leading to another, I am currently centralizing constants, and
found that enums can hold doubles (which is quite nice), but I have no
way of defining NaN or Inf as a constant, is there such a way?

Really? My reading of /sys/src/libc/port/nan.c makes me think NaN(2)
returns a uvlong value of 0x7ff1, miss I something?
On the other hand, the assignment of NaN to a double de

It uses i²s to for the data (sound) transport. the control for the codec
is seperate, the codec is a cs42l51, which has an i²s interface for data

i've been working on an an audio driver for the kirkwood for a while now,
indeed it's been working well for a while now. at this point i'm mostly
struggling to figure out the mixer/controls/codec filesystem interface.
if any of this is incorrect, please correct me.

my concern with audioctl is multiple channels. for now control-left and
control-right are fine (if clunky), with 5.1 (or 7.1) audio that becomes

The general idea here is that forking a new process is not usually

there's other overhead to trim first, and if you really need t

/sys/src/cmd/usb/ether/ether.c says

Which sounds promising, but I can't seem to find any references to
etherfile anywhere else.
Does it exist?
