From 9ca8dbcc65cfc63d6f5ef3312a33184e1d726e00 Mon Sep 17 00:00:00 2001 From: Yunhong Jiang Date: Tue, 4 Aug 2015 12:17:53 -0700 Subject: Add the rt linux 4.1.3-rt3 as base Import the rt linux 4.1.3-rt3 as OPNFV kvm base. It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and the base is: commit 0917f823c59692d751951bf5ea699a2d1e2f26a2 Author: Sebastian Andrzej Siewior Date: Sat Jul 25 12:13:34 2015 +0200 Prepare v4.1.3-rt3 Signed-off-by: Sebastian Andrzej Siewior We lose all the git history this way and it's not good. We should apply another opnfv project repo in future.

If you are +unfamiliar with configuring sound under Linux, please read the +Sound-HOWTO, Documentation/sound/oss/Introduction and other +relevant docs first. + +The following information is relevant information from README.OSS +and legacy docs for the Pro Audio Spectrum 16 (PAS16): +================================================================== + +The pas2_card.c driver supports the following cards -- +Pro Audio Spectrum 16 (PAS16) and compatibles: + Pro Audio Spectrum 16 + Pro Audio Studio 16 + Logitech Sound Man 16 + NOTE! The original Pro Audio Spectrum as well as the PAS+ are not + and will not be supported by the driver. + +The sound driver configuration dialog +------------------------------------- + +Sound configuration starts by making some yes/no questions. Be careful +when answering to these questions since answering y to a question may +prevent some later ones from being asked. For example don't answer y to +the question about (PAS16) if you don't really have a PAS16. Sound +configuration may also be made modular by answering m to configuration +options presented. + +Note also that all questions may not be asked. The configuration program +may disable some questions depending on the earlier choices. It may also +select some options automatically as well. + + "ProAudioSpectrum 16 support", + - Answer 'y'_ONLY_ if you have a Pro Audio Spectrum _16_, + Pro Audio Studio 16 or Logitech SoundMan 16 (be sure that + you read the above list correctly). Don't answer 'y' if you + have some other card made by Media Vision or Logitech since they + are not PAS16 compatible. + NOTE! Since 3.5-beta10 you need to enable SB support (next question) + if you want to use the SB emulation of PAS16. It's also possible to + the emulation if you want to use a true SB card together with PAS16 + (there is another question about this that is asked later). + + "Generic OPL2/OPL3 FM synthesizer support", + - Answer 'y' if your card has a FM chip made by Yamaha (OPL2/OPL3/OPL4). + The PAS16 has an OPL3-compatible FM chip. + +With PAS16 you can use two audio device files at the same time. /dev/dsp (and +/dev/audio) is connected to the 8/16 bit native codec and the /dev/dsp1 (and +/dev/audio1) is connected to the SB emulation (8 bit mono only). + + +The new stuff for 2.3.99 and later +============================================================================ +The following configuration options are relevant to configuring the PAS16: + +Sound card support +CONFIG_SOUND + If you have a sound card in your computer, i.e. if it can say more + than an occasional beep, say Y. Be sure to have all the information + about your sound card and its configuration down (I/O port, + interrupt and DMA channel), because you will be asked for it. + + You want to read the Sound-HOWTO, available from + http://www.tldp.org/docs.html#howto . General information + about the modular sound system is contained in the files + Documentation/sound/oss/Introduction. The file + Documentation/sound/oss/README.OSS contains some slightly outdated but + still useful information as well. + +OSS sound modules +CONFIG_SOUND_OSS + OSS is the Open Sound System suite of sound card drivers. They make + sound programming easier since they provide a common API. Say Y or M + here (the module will be called sound.o) if you haven't found a + driver for your sound card above, then pick your driver from the + list below. + +Persistent DMA buffers +CONFIG_SOUND_DMAP + Linux can often have problems allocating DMA buffers for ISA sound + cards on machines with more than 16MB of RAM. This is because ISA + DMA buffers must exist below the 16MB boundary and it is quite + possible that a large enough free block in this region cannot be + found after the machine has been running for a while. If you say Y + here the DMA buffers (64Kb) will be allocated at boot time and kept + until the shutdown. This option is only useful if you said Y to + "OSS sound modules", above. If you said M to "OSS sound modules" + then you can get the persistent DMA buffer functionality by passing + the command-line argument "dmabuf=1" to the sound.o module. + + Say y here for PAS16. + +ProAudioSpectrum 16 support +CONFIG_SOUND_PAS + Answer Y only if you have a Pro Audio Spectrum 16, ProAudio Studio + 16 or Logitech SoundMan 16 sound card. Don't answer Y if you have + some other card made by Media Vision or Logitech since they are not + PAS16 compatible. It is not necessary to enable the separate + Sound Blaster support; it is included in the PAS driver. + + If you compile the driver into the kernel, you have to add + "pas2=,,,,,,, + to the kernel command line. + +FM Synthesizer (YM3812/OPL-3) support +CONFIG_SOUND_YM3812 + Answer Y if your card has a FM chip made by Yamaha (OPL2/OPL3/OPL4). + Answering Y is usually a safe and recommended choice, however some + cards may have software (TSR) FM emulation. Enabling FM support with + these cards may cause trouble (I don't currently know of any such + cards, however). + Please read the file Documentation/sound/oss/OPL3 if your card has an + OPL3 chip. + If you compile the driver into the kernel, you have to add + "opl3=" to the kernel command line. + + If you compile your drivers into the kernel, you MUST configure + OPL3 support as a module for PAS16 support to work properly. + You can then get OPL3 functionality by issuing the command: + insmod opl3 + In addition, you must either add the following line to + /etc/modprobe.d/*.conf: + options opl3 io=0x388 + or else add the following line to /etc/lilo.conf: + opl3=0x388 + + +EXAMPLES +=================================================================== +To use the PAS16 in my computer I have enabled the following sound +configuration options: + +CONFIG_SOUND=y +CONFIG_SOUND_OSS=y +CONFIG_SOUND_TRACEINIT=y +CONFIG_SOUND_DMAP=y +CONFIG_SOUND_PAS=y +CONFIG_SOUND_SB=n +CONFIG_SOUND_YM3812=m + +I have also included the following append line in /etc/lilo.conf: +append="pas2=0x388,10,3,-1,0x220,5,1,-1 sb=0x220,5,1,-1 opl3=0x388" + +The io address of 0x388 is default configuration on the PAS16. The +irq of 10 and dma of 3 may not match your installation. The above +configuration enables PAS16, 8-bit Soundblaster and OPL3 +functionality. If Soundblaster functionality is not desired, the +following line would be appropriate: +append="pas2=0x388,10,3,-1,0,-1,-1,-1 opl3=0x388" + +If sound is built totally modular, the above options may be +specified in /etc/modprobe.d/*.conf for pas2, sb and opl3 +respectively. -- cgit 1.2.3-korg
