PVR-150 on 6-STABLE: success and mini HOWTO

Wed Dec 19 08:14:44 PST 2007

I just completed setting up my brand new Hauppauge PVR-150 (MCE I think) on 
6.2-STABLE using the newish port from usleep. All this info can be found, but 
it is scattered, so I thought it might be useful to put together a short step 
by step guide:

PVR-150 (MCE) on FreeBSD-6-STABLE
=================================

desktop# uname -a
FreeBSD desktop.homenet 6.2-STABLE FreeBSD 6.2-STABLE #0: Tue Aug 21 02:19:27 
CEST 2007     root at desktop.homenet:/usr/obj/usr/src/sys/DESKTOP  i386

Step 1
======
Download and extract the newer port:

desktop# cd /usr/ports/multimedia
desktop# wget http://usleepless.110mb.com/pvrxxx_port.tgz
desktop# cp -R pvrxxx pvrxxx.old
desktop# tar xvf pvrxxx_port.tgz && chown -R root:wheel pvrxxx
desktop# cp -R pvrxxx pvrxxx.new
desktop# rm pvrxxx_port.tgz

Step 2
======
Patch iicbus:

desktop# cd pvrxxx
desktop# make patch-iicbb

(on my box one iicbus_if.m patch gets ignored because the change was already 
made)

Step 3
======
Rebuild your kernel, or just the iic modules:

[ desktop# kldunload iicbus (only if loaded, I also had iic loaded for saa) ]
desktop# cd /usr/src/sys/modules/i2c
desktop# make all install clean (you could also build only iicbus and iicbb)
desktop# kldload iicbus
desktop# kldload iicbb

Step 4
======
Build and install the port:

desktop# cd /usr/ports/multimedia/pvrxxx
desktop# make install clean

Step 5
======
Load the cxm modules:

desktop# kldload cxm_iic
desktop# kldload cxm (this takes ~10 seconds, don't panic unless the kernel 
does)
desktop# kldstat

Exiting... (End of file)

Woohoo!

To play from mplayer directly:

%mplayer -cache 4096 /dev/cxm0

Cache is needed to avoid buffer underruns which would make the video slow.

Consecutive tuning:

Won't work if mplayer keeps playing (BT848_SCAPAREA can't be set), but it does 
work if you *pause* mplayer and after tuning resume playing. This can be 
scripted.

Step 7
======
Make changes (module loading) permanent in /boot/loader.conf:

# PVR-150
iicbus_load="YES"
iicbb_load="YES"
cxm_iic_load="YES"

The cxm module MUST be loaded AFTER cxm_iic. Our loader seems to IGNORE the 
order, and because of this your kernel will panic because it gets the cxm 
before cxm_iic which makes the firmware upload fail! Alternatively, or 
concurrently, it may be so that there's no way to read the firmware in this 
stage.

If this happens to you (you have put cxm in loader.conf), enter the loader 
prompt, unload all modules, and disable the loading of cxm, then 'boot'.

To have the cxm module be auto-loaded post-boot you can for example put this 
in /usr/local/etc/rc.d/cxm (and cxm_enable="YES" in /etc/rc.conf):

#!/bin/sh
#
# $NetBSD:  $
# $FreeBSD: $
#

# PROVIDE: cxm

. /etc/rc.subr

name="cxm"
kldload_cmd="/sbin/kldload"
kldunload_cmd="/sbin/kldunload"
start_cmd="cxm_start"
stop_cmd="cxm_stop"

cxm_start()
{
	if [ -x "${kldload_cmd}" ]; then
		${kldload_cmd} ${name}
	fi
}

cxm_stop()
{
	if [ -x "${kldunload_cmd}" ]; then
		${kldunload_cmd} ${name}
	fi
}

load_rc_config $name
run_rc_command "$1"

This keeps the firmware klds loaded, but who cares, it works :)

That's all folks.
