ucodeadm(1M) System Administration Commands ucodeadm(1M)NAME
ucodeadm - update processor microcode
SYNOPSIS
/usr/sbin/ucodeadm -v
/usr/sbin/ucodeadm -umicrocode-text-file
/usr/sbin/ucodeadm -i [-R path] microcode-text-file
DESCRIPTION
The ucodeadm utility can be used to report running microcode revision on the processors, update microcode, or install microcode on the tar-
get system to be used during the boot process.
The microcode-text-file can be obtained from processor vendors.
OPTIONS -v Report microcode revision.
-u microcode-text-file Update microcode on all cross-call interrupt ready processors.
-i microcode-text-file Install microcode files on target system to be used during the next boot cycle. The text file name must have
the vendor name prefix, such as "intel" or "amd".
By default the microcode files will be installed at:
/platform/i86pc/ucode/$VENDORSTR/
where VENDORSTR is either "GenuineIntel" or "AuthenticAMD".
-R alternate path Install microcode path in the alternate path.
EXAMPLES
Example 1 Reporting the Microcode Revision
The following example displays the microcode revision that is currently running:
# ucodeadm -v
Example 2 Updating the Processor Microcode
The following example updates the processor microcode to intel-ucode.txt:
# ucodeadm -u intel-ucode.txt
Example 3 Installing the Microcode on the Target System
The following example installs the microcode on the target system, /export/ucode-path:
# ucodeadm -i -R /export/ucode-path intel-ucode.txt
If an alternate path is used when installing the microcode on the target system, the installed microcode file is not used on the next boot
cycle.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.

cspctl(1) General Commands Manual cspctl(1)NAME
cspctl - Sound Blaster 16 ASP/CSP control program
SYNOPSIS
cspctl command [-options] <filename>
DESCRIPTION
cspctl is a simple CSP microcode loader for Crative Sound Blaster 16ASP and some Sound Blaster AWE32 sound cards with Creative Signal Pro-
cessor (CSP) chip (CT1748A) installed. cspctl can also be used as a post-install function to snd-sb16-csp module to load default codec at
module installation. If CSP chip is successfully detected and initialized, it will be installed as a hardware dependent device hwC0D2 into
/dev/snd directory. Currently, following codecs can be loaded to CSP device:
wfm0001a.csp QSound decoder
wfm0006a.csp A-law codec
wfm0007a.csp u-law codec
wfm0011a.csp IMA ADPCM codec (distorted output for IMA test files)
wfm0200a.csp Creative ADPCM codec (sounds like Intel/DVI IMA ADPCM compatible)
wfm0202a.csp Fast Speech 8 codec
wfm0203a.csp Fast Speech 10 codec
These codecs are not yet supported by ALSA:
wfm0201a.csp Text2Speech decoder
Qsound microcode file has four functions, each function is a decoder for different sample rate. Rates for QSound functions #1, #2, #3 and
#4 are 44100, 22050, 11025 and 8000Hz respectively. IMA ADPCM and FastSpeech codecs are formed of two functions, the first one is for cap-
ture and the second one is for playback. A-law and u-law codecs have only one function. To load for example function #2 from QSound
microcode file (decoder for 22050Hz), run as follows:
% cspctl load -f 2 -d QSound wfm0001a.csp
After successful loading, /proc/asound/SB16/cspD2 will show:
Creative Signal Processor [v1.0]
State: -x--L
Codec: QSound [func #2]
Sample rates: 22050Hz
QSound decoder disabled
With QSound decoder microcode loaded, all simple PCM file formats can be played with QSound 180 degree positioning applied. QSound element
is dynamically added into mixer structure as 3DEffect1-space element. It will only show if support for CSP has been compiled into ALSA
drivers, CSP chip has been found, and QSound codec is loaded into CSP. When enabled, QSound position can be dynamically changed by mixer
slider, and proc interface should follow the state of CSP chip and its current QSound position:
Creative Signal Processor [v1.0]
State: Qx-RL
Codec: QSound [func #2]
Sample rates: 22050Hz
QSound decoder enabled
Processing 16bit mono PCM samples
Qsound position: left = 0x9, right = 0x9
Driver supports autoloading of u-Law, A-Law and Ima-ADPCM hardware codecs. Autoloading is active only when there is no microcode loaded to
CSP, and there is no need to preload appropriate *.csp files. To unload manually loaded microcode, you should run
% cspctl unload
If hardware codec microcode has been manually loaded, then CSP will support only loaded PCM format and autoloading will be disabled. In
such case, proc interface will show loaded codec properties:
Creative Signal Processor [v1.0]
State: -x--L
Codec: IMA-ADPCM [func #2]
Sample rates: All
PCM format ID: 0x400000 (16bit/-) [mono/stereo] [playback/-]
COMMANDS
load Load microcode from filename to CSP.
unload Unload microcode from CSP.
OPTIONS -h, --help
Display a short help.
-c card
Select a card number. Option defaults to 0.
-f function
Select a function from microcode file. Option defaults to 1.
-d description
Optional microcode description string.
