2 | Advanced Linux Sound Architecture - Driver | |
3 | ========================================== | |
4 | Configuration guide | |
5 | ||
6 | ||
7 | Kernel Configuration | |
8 | ==================== | |
9 | ||
10 | To enable ALSA support you need at least to build the kernel with | |
11 | primary sound card support (CONFIG_SOUND). Since ALSA can emulate OSS, | |
12 | you don't have to choose any of the OSS modules. | |
13 | ||
14 | Enable "OSS API emulation" (CONFIG_SND_OSSEMUL) and both OSS mixer and | |
15 | PCM supports if you want to run OSS applications with ALSA. | |
16 | ||
17 | If you want to support the WaveTable functionality on cards such as | |
18 | SB Live! then you need to enable "Sequencer support" | |
19 | (CONFIG_SND_SEQUENCER). | |
20 | ||
21 | To make ALSA debug messages more verbose, enable the "Verbose printk" | |
22 | and "Debug" options. To check for memory leaks, turn on "Debug memory" | |
23 | too. "Debug detection" will add checks for the detection of cards. | |
24 | ||
25 | Please note that all the ALSA ISA drivers support the Linux isapnp API | |
26 | (if the card supports ISA PnP). You don't need to configure the cards | |
27 | using isapnptools. | |
28 | ||
29 | ||
30 | Creating ALSA devices | |
31 | ===================== | |
32 | ||
33 | This depends on your distribution, but normally you use the /dev/MAKEDEV | |
34 | script to create the necessary device nodes. On some systems you use a | |
35 | script named 'snddevices'. | |
36 | ||
37 | ||
38 | Module parameters | |
39 | ================= | |
40 | ||
41 | The user can load modules with options. If the module supports more than | |
42 | one card and you have more than one card of the same type then you can | |
43 | specify multiple values for the option separated by commas. | |
44 | ||
45 | Prior to version 0.9.0rc4 options had a 'snd_' prefix. This was removed. | |
46 | ||
47 | Module snd | |
48 | ---------- | |
49 | ||
50 | The core ALSA module. It is used by all ALSA card drivers. | |
51 | It takes the following options which have global effects. | |
52 | ||
53 | major - major number for sound driver | |
54 | - Default: 116 | |
55 | cards_limit | |
56 | - limiting card index for auto-loading (1-8) | |
57 | - Default: 1 | |
58 | - For auto-loading more than one card, specify this | |
59 | option together with snd-card-X aliases. | |
304cd07f TI |
60 | slots - Reserve the slot index for the given driver. |
61 | This option takes multiple strings. | |
62 | See "Module Autoloading Support" section for details. | |
1da177e4 LT |
63 | |
64 | Module snd-pcm-oss | |
65 | ------------------ | |
66 | ||
67 | The PCM OSS emulation module. | |
68 | This module takes options which change the mapping of devices. | |
69 | ||
70 | dsp_map - PCM device number maps assigned to the 1st OSS device. | |
71 | - Default: 0 | |
72 | adsp_map - PCM device number maps assigned to the 2st OSS device. | |
73 | - Default: 1 | |
74 | nonblock_open | |
6243008b | 75 | - Don't block opening busy PCM devices. Default: 1 |
1da177e4 LT |
76 | |
77 | For example, when dsp_map=2, /dev/dsp will be mapped to PCM #2 of | |
78 | the card #0. Similarly, when adsp_map=0, /dev/adsp will be mapped | |
79 | to PCM #0 of the card #0. | |
80 | For changing the second or later card, specify the option with | |
81 | commas, such like "dsp_map=0,1". | |
82 | ||
83 | nonblock_open option is used to change the behavior of the PCM | |
84 | regarding opening the device. When this option is non-zero, | |
85 | opening a busy OSS PCM device won't be blocked but return | |
86 | immediately with EAGAIN (just like O_NONBLOCK flag). | |
87 | ||
88 | Module snd-rawmidi | |
89 | ------------------ | |
90 | ||
91 | This module takes options which change the mapping of devices. | |
92 | similar to those of the snd-pcm-oss module. | |
93 | ||
94 | midi_map - MIDI device number maps assigned to the 1st OSS device. | |
95 | - Default: 0 | |
96 | amidi_map - MIDI device number maps assigned to the 2st OSS device. | |
97 | - Default: 1 | |
98 | ||
99 | Common parameters for top sound card modules | |
100 | -------------------------------------------- | |
101 | ||
102 | Each of top level sound card module takes the following options. | |
103 | ||
104 | index - index (slot #) of sound card | |
0ef797c5 | 105 | - Values: 0 through 31 or negative |
1da177e4 LT |
106 | - If nonnegative, assign that index number |
107 | - if negative, interpret as a bitmask of permissible | |
108 | indices; the first free permitted index is assigned | |
109 | - Default: -1 | |
110 | id - card ID (identifier or name) | |
111 | - Can be up to 15 characters long | |
112 | - Default: the card type | |
113 | - A directory by this name is created under /proc/asound/ | |
114 | containing information about the card | |
115 | - This ID can be used instead of the index number in | |
116 | identifying the card | |
117 | enable - enable card | |
118 | - Default: enabled, for PCI and ISA PnP cards | |

120 | Module snd-adlib |
121 | ---------------- | |
122 | ||
123 | Module for AdLib FM cards. | |
124 | ||
125 | port - port # for OPL chip | |
126 | ||
127 | This module supports multiple cards. It does not support autoprobe, so | |
128 | the port must be specified. For actual AdLib FM cards it will be 0x388. | |
129 | Note that this card does not have PCM support and no mixer; only FM | |
130 | synthesis. | |
131 | ||
132 | Make sure you have "sbiload" from the alsa-tools package available and, | |
133 | after loading the module, find out the assigned ALSA sequencer port | |
134 | number through "sbiload -l". Example output: | |
135 | ||
136 | Port Client name Port name | |
137 | 64:0 OPL2 FM synth OPL2 FM Port | |
138 | ||
139 | Load the std.sb and drums.sb patches also supplied by sbiload: | |
140 | ||
141 | sbiload -p 64:0 std.sb drums.sb | |
142 | ||
143 | If you use this driver to drive an OPL3, you can use std.o3 and drums.o3 | |
144 | instead. To have the card produce sound, use aplaymidi from alsa-utils: | |
145 | ||
146 | aplaymidi -p 64:0 foo.mid | |
147 | ||

767 | Each codec may have a model table for different configurations. |
768 | If your machine isn't listed there, the default (usually minimal) | |
769 | configuration is set up. You can pass "model=<name>" option to | |
770 | specify a certain model in such a case. There are different | |
cae51176 TI |
771 | models depending on the codec chip. The list of available models |
772 | is found in HD-Audio-Models.txt | |
db064e50 | 773 | |
6d7b1d7d TI |
774 | The model name "genric" is treated as a special case. When this |
775 | model is given, the driver uses the generic codec parser without | |
776 | "codec-patch". It's sometimes good for testing and debugging. | |
777 | ||
6243008b | 778 | If the default configuration doesn't work and one of the above |
30bc4481 TI |

c74db86b TI |
786 | Note 2: If you get click noises on output, try the module option |
787 | position_fix=1 or 2. position_fix=1 will use the SD_LPIB | |
788 | register value without FIFO size correction as the current | |
789 | DMA pointer. position_fix=2 will make the driver to use | |
790 | the position buffer instead of reading SD_LPIB register. | |
90f31e38 | 791 | (Usually SD_LPIB register is more accurate than the |
c74db86b TI |
792 | position buffer.) |
793 | ||
27346166 TI |
794 | NB: If you get many "azx_get_response timeout" messages at |
795 | loading, it's likely a problem of interrupts (e.g. ACPI irq | |
796 | routing). Try to boot with options like "pci=noacpi". Also, you | |
797 | can try "single_cmd=1" module option. This will switch the | |
798 | communication method between HDA controller and codecs to the | |
799 | single immediate commands instead of CORB/RIRB. Basically, the | |
800 | single command mode is provided only for BIOS, and you won't get | |
801 | unsolicited events, too. But, at least, this works independently | |
802 | from the irq. Remember this is a last resort, and should be | |
803 | avoided as much as possible... | |
804 | ||
95904743 TI |
805 | MORE NOTES ON "azx_get_response timeout" PROBLEMS: |
806 | On some hardwares, you may need to add a proper probe_mask option | |
807 | to avoid the "azx_get_response timeout" problem above, instead. | |
808 | This occurs when the access to non-existing or non-working codec slot | |
809 | (likely a modem one) causes a stall of the communication via HD-audio | |
810 | bus. You can see which codec slots are probed by enabling | |
62cf872a | 811 | CONFIG_SND_DEBUG_VERBOSE, or simply from the file name of the codec |
95904743 TI |
812 | proc files. Then limit the slots to probe by probe_mask option. |
813 | For example, probe_mask=1 means to probe only the first slot, and | |
814 | probe_mask=4 means only the third slot. | |

1222 | to initialize/use ac97 although it's not detected. In such a | |
1223 | case, use force_ac97=1 option - but *NO* guarantee whether it | |
1224 | works! | |
1225 | ||
1226 | Note: The NM256 chip can be linked internally with non-AC97 | |
1227 | codecs. This driver supports only the AC97 codec, and won't work | |
1228 | with machines with other (most likely CS423x or OPL3SAx) chips, | |
1229 | even though the device is detected in lspci. In such a case, try | |
1230 | other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP | |
6243008b | 1231 | but some doesn't have ISA PnP. You'll need to specify isapnp=0 |
1da177e4 LT |
1232 | and proper hardware parameters in the case without ISA PnP. |
1233 | ||
1234 | Note: some laptops need a workaround for AC97 RESET. For the | |
1235 | known hardware like Dell Latitude LS and Sony PCG-F305, this | |
1236 | workaround is enabled automatically. For other laptops with a | |
1237 | hard freeze, you can try reset_workaround=1 option. | |
1238 | ||
d1f38cf9 TI |
1239 | Note: Dell Latitude CSx laptops have another problem regarding |
1240 | AC97 RESET. On these laptops, reset_workaround2 option is | |
1241 | turned on as default. This option is worth to try if the | |
1242 | previous reset_workaround option doesn't help. | |
1243 | ||
1da177e4 LT |
1244 | Note: This driver is really crappy. It's a porting from the |
1245 | OSS driver, which is a result of black-magic reverse engineering. | |
1246 | The detection of codec will fail if the driver is loaded *after* | |
1247 | X-server as described above. You might be able to force to load | |
1248 | the module, but it may result in hang-up. Hence, make sure that | |
1249 | you load this module *before* X if you encounter this kind of | |
1250 | problem. | |

1582 | The below are options for wavefront_synth features: |
1583 | wf_raw - Assume that we need to boot the OS (default:no) | |
1584 | If yes, then during driver loading, the state of the board is | |
1585 | ignored, and we reset the board and load the firmware anyway. | |
1586 | fx_raw - Assume that the FX process needs help (default:yes) | |
1587 | If false, we'll leave the FX processor in whatever state it is | |
1588 | when the driver is loaded. The default is to download the | |
1589 | microprogram and associated coefficients to set it up for | |
1590 | "default" operation, whatever that means. | |
1591 | debug_default - Debug parameters for card initialization | |
1592 | wait_usecs - How long to wait without sleeping, usecs | |
1593 | (default:150) | |
1594 | This magic number seems to give pretty optimal throughput | |
1595 | based on my limited experimentation. | |
1596 | If you want to play around with it and find a better value, be | |
1597 | my guest. Remember, the idea is to get a number that causes us | |
1598 | to just busy wait for as many WaveFront commands as possible, | |
1599 | without coming up with a number so large that we hog the whole | |
1600 | CPU. | |
1601 | Specifically, with this number, out of about 134,000 status | |

1da177e4 | 1747 | |
b7fe4622 | 1748 | This module supports one chip and autoprobe. |
1da177e4 LT |
1749 | |
1750 | Note: on some SMP motherboards like MSI 694D the interrupts might | |
1751 | not be generated properly. In such a case, please try to | |
1752 | set the SMP (or MPS) version on BIOS to 1.1 instead of | |
1753 | default value 1.4. Then the interrupt number will be | |
1754 | assigned under 15. You might also upgrade your BIOS. | |
1755 | ||
2d7eb7cb | 1756 | Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound) |
1da177e4 | 1757 | channels as the first PCM. On these channels, up to 4 |
2d7eb7cb SV |
1758 | streams can be played at the same time, and the controller |
1759 | can perform sample rate conversion with separate rates for | |
1760 | each channel. | |
1da177e4 LT |
1761 | As default (dxs_support = 0), 48k fixed rate is chosen |
1762 | except for the known devices since the output is often | |
1763 | noisy except for 48k on some mother boards due to the | |
1764 | bug of BIOS. | |
2d7eb7cb | 1765 | Please try once dxs_support=5 and if it works on other |
1da177e4 LT |
1766 | sample rates (e.g. 44.1kHz of mp3 playback), please let us |
1767 | know the PCI subsystem vendor/device id's (output of | |
1768 | "lspci -nv"). | |
cdc27f3a TI |
1769 | If dxs_support=5 does not work, try dxs_support=4; if it |
1770 | doesn't work too, try dxs_support=1. (dxs_support=1 is | |
6243008b | 1771 | usually for old motherboards. The correct implemented |
cdc27f3a | 1772 | board should work with 4 or 5.) If it still doesn't |
1da177e4 LT |
1773 | work and the default setting is ok, dxs_support=3 is the |
1774 | right choice. If the default setting doesn't work at all, | |
1775 | try dxs_support=2 to disable the DXS channels. | |
1776 | In any cases, please let us know the result and the | |
6243008b TI |
1777 | subsystem vendor/device ids. See "Links and Addresses" |
1778 | below. | |

1da177e4 LT |
1827 | |
1828 | When the driver is compiled as a module and the hotplug firmware | |
1829 | is supported, the firmware data is loaded via hotplug automatically. | |
1830 | Install the necessary firmware files in alsa-firmware package. | |
1831 | When no hotplug fw loader is available, you need to load the | |
1832 | firmware via vxloader utility in alsa-tools package. To invoke | |
1833 | vxloader automatically, add the following to /etc/modprobe.conf | |
1834 | ||
1835 | install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader | |
1836 | ||
1837 | (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to | |
1838 | /etc/modules.conf, instead.) | |
1839 | IBL size defines the interrupts period for PCM. The smaller size | |
1840 | gives smaller latency but leads to more CPU consumption, too. | |
1841 | The size is usually aligned to 126. As default (=0), the smallest | |
1842 | size is chosen. The possible IBL values can be found in | |
1843 | /proc/asound/cardX/vx-status proc file. | |

1da177e4 LT |
1855 | PCMCIA is supported on kernel. |
1856 | ||
6243008b TI |
1857 | With the older 2.6.x kernel, to activate the driver via the card |
1858 | manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the | |
1859 | sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no | |
1860 | longer require a config file. | |
1da177e4 LT |
1861 | |
1862 | When the driver is compiled as a module and the hotplug firmware | |

1900 | AC97 Quirk Option |
1901 | ================= | |
1902 | ||
1903 | The ac97_quirk option is used to enable/override the workaround for | |
1904 | specific devices on drivers for on-board AC'97 controllers like | |
1905 | snd-intel8x0. Some hardware have swapped output pins between Master | |
1906 | and Headphone, or Surround (thanks to confusion of AC'97 | |
1907 | specifications from version to version :-) | |
1908 | ||
1909 | The driver provides the auto-detection of known problematic devices, | |
1910 | but some might be unknown or wrongly detected. In such a case, pass | |
1911 | the proper value with this option. | |
1912 | ||
1913 | The following strings are accepted: | |
1914 | - default Don't override the default setting | |
10e4097f | 1915 | - none Disable the quirk |
6243008b TI |
1916 | - hp_only Bind Master and Headphone controls as a single control |
1917 | - swap_hp Swap headphone and master controls | |
1918 | - swap_surround Swap master and surround controls | |
1919 | - ad_sharing For AD1985, turn on OMS bit and use headphone | |
1920 | - alc_jack For ALC65x, turn on the jack sense mode | |
1921 | - inv_eapd Inverted EAPD implementation | |
1922 | - mute_led Bind EAPD bit for turning on/off mute LED | |
1923 | ||
1924 | For backward compatibility, the corresponding integer value -1, 0, | |
1925 | ... are accepted, too. | |
1926 | ||
1927 | For example, if "Master" volume control has no effect on your device | |
1928 | but only "Headphone" does, pass ac97_quirk=hp_only module option. | |
1929 | ||
1930 | ||
1da177e4 LT |
1931 | Configuring Non-ISAPNP Cards |
1932 | ============================ | |
1933 | ||
1934 | When the kernel is configured with ISA-PnP support, the modules | |
1935 | supporting the isapnp cards will have module options "isapnp". | |
1936 | If this option is set, *only* the ISA-PnP devices will be probed. | |
1937 | For probing the non ISA-PnP cards, you have to pass "isapnp=0" option | |
1938 | together with the proper i/o and irq configuration. | |
1939 | ||
1940 | When the kernel is configured without ISA-PnP support, isapnp option | |
1941 | will be not built in. | |
1942 | ||
1943 | ||
1944 | Module Autoloading Support | |
1945 | ========================== | |
1946 | ||
1947 | The ALSA drivers can be loaded automatically on demand by defining | |
1948 | module aliases. The string 'snd-card-%1' is requested for ALSA native | |
1949 | devices where %i is sound card number from zero to seven. | |
1950 | ||
1951 | To auto-load an ALSA driver for OSS services, define the string | |
1952 | 'sound-slot-%i' where %i means the slot number for OSS, which | |
1953 | corresponds to the card index of ALSA. Usually, define this | |
d533f671 | 1954 | as the same card module. |
1da177e4 LT |
1955 | |
1956 | An example configuration for a single emu10k1 card is like below: | |
1957 | ----- /etc/modprobe.conf | |
1958 | alias snd-card-0 snd-emu10k1 | |
1959 | alias sound-slot-0 snd-emu10k1 | |
1960 | ----- /etc/modprobe.conf | |
1961 | ||
1962 | The available number of auto-loaded sound cards depends on the module | |
1963 | option "cards_limit" of snd module. As default it's set to 1. | |
1964 | To enable the auto-loading of multiple cards, specify the number of | |
1965 | sound cards in that option. | |
1966 | ||
1967 | When multiple cards are available, it'd better to specify the index | |
1968 | number for each card via module option, too, so that the order of | |
1969 | cards is kept consistent. | |
1970 | ||
1971 | An example configuration for two sound cards is like below: | |
1972 | ||
1973 | ----- /etc/modprobe.conf | |
1974 | # ALSA portion | |
1975 | options snd cards_limit=2 | |
1976 | alias snd-card-0 snd-interwave | |
1977 | alias snd-card-1 snd-ens1371 | |
1978 | options snd-interwave index=0 | |
1979 | options snd-ens1371 index=1 | |
1980 | # OSS/Free portion | |
1981 | alias sound-slot-0 snd-interwave | |
1982 | alias sound-slot-1 snd-ens1371 | |
2fe0ae78 | 1983 | ----- /etc/modprobe.conf |
1da177e4 LT |

1985 | In this example, the interwave card is always loaded as the first card | |
1986 | (index 0) and ens1371 as the second (index 1). | |
1987 | ||
304cd07f TI |
1988 | Alternative (and new) way to fixate the slot assignment is to use |
1989 | "slots" option of snd module. In the case above, specify like the | |
1990 | following: | |
1991 | ||
1992 | options snd slots=snd-interwave,snd-ens1371 | |
1993 | ||
1994 | Then, the first slot (#0) is reserved for snd-interwave driver, and | |
1995 | the second (#1) for snd-ens1371. You can omit index option in each | |
1996 | driver if slots option is used (although you can still have them at | |
1997 | the same time as long as they don't conflict). | |
1998 | ||
1999 | The slots option is especially useful for avoiding the possible | |
2000 | hot-plugging and the resultant slot conflict. For example, in the | |
2001 | case above again, the first two slots are already reserved. If any | |
2002 | other driver (e.g. snd-usb-audio) is loaded before snd-interwave or | |
2003 | snd-ens1371, it will be assigned to the third or later slot. | |
2004 | ||

2005 | When a module name is given with '!', the slot will be given for any |
2006 | modules but that name. For example, "slots=!snd-pcsp" will reserve | |
2007 | the first slot for any modules but snd-pcsp. | |

2010 | ALSA PCM devices to OSS devices mapping | |
2011 | ======================================= | |
2012 | ||
2013 | /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4 | |
2014 | /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3 | |
2015 | /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12 | |
2016 | /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20 | |
2017 | /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19 | |
2018 | /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28 | |
2019 | /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36 | |
2020 | /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39 | |
2021 | /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44 | |
2022 | ||
2023 | The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means | |
2024 | sound card number and second means device number. The ALSA devices | |
2025 | have either 'c' or 'p' suffix indicating the direction, capture and | |
2026 | playback, respectively. | |
2027 | ||
2028 | Please note that the device mapping above may be varied via the module | |
2029 | options of snd-pcm-oss module. | |

2032 | Proc interfaces (/proc/asound) |
2033 | ============================== | |
2034 | ||
2035 | /proc/asound/card#/pcm#[cp]/oss | |
2036 | ------------------------------- | |
2037 | String "erase" - erase all additional informations about OSS applications | |
2038 | String "<app_name> <fragments> <fragment_size> [<options>]" | |
2039 | ||
2040 | <app_name> - name of application with (higher priority) or without path | |
2041 | <fragments> - number of fragments or zero if auto | |
2042 | <fragment_size> - size of fragment in bytes or zero if auto | |
2043 | <options> - optional parameters | |
2044 | - disable the application tries to open a pcm device for | |
2045 | this channel but does not want to use it. | |
2046 | (Cause a bug or mmap needs) | |
2047 | It's good for Quake etc... | |
2048 | - direct don't use plugins | |
2049 | - block force block mode (rvplayer) | |
2050 | - non-block force non-block mode | |
2051 | - whole-frag write only whole fragments (optimization affecting | |
2052 | playback only) | |
2053 | - no-silence do not fill silence ahead to avoid clicks | |
10f69f9e TI |
2054 | - buggy-ptr Returns the whitespace blocks in GETOPTR ioctl |
2055 | instead of filled blocks | |

2062 | Early Buffer Allocation |
2063 | ======================= | |
2064 | ||
2065 | Some drivers (e.g. hdsp) require the large contiguous buffers, and | |
2066 | sometimes it's too late to find such spaces when the driver module is | |
2067 | actually loaded due to memory fragmentation. You can pre-allocate the | |
2068 | PCM buffers by loading snd-page-alloc module and write commands to its | |
2069 | proc file in prior, for example, in the early boot stage like | |
2070 | /etc/init.d/*.local scripts. | |
2071 | ||
2072 | Reading the proc file /proc/drivers/snd-page-alloc shows the current | |
2073 | usage of page allocation. In writing, you can send the following | |
2074 | commands to the snd-page-alloc driver: | |
2075 | ||
2076 | - add VENDOR DEVICE MASK SIZE BUFFERS | |
2077 | ||
2078 | VENDOR and DEVICE are PCI vendor and device IDs. They take | |
2079 | integer numbers (0x prefix is needed for the hex). | |
2080 | MASK is the PCI DMA mask. Pass 0 if not restricted. | |
2081 | SIZE is the size of each buffer to allocate. You can pass | |
2082 | k and m suffix for KB and MB. The max number is 16MB. | |
2083 | BUFFERS is the number of buffers to allocate. It must be greater | |
2084 | than 0. The max number is 4. | |
2085 | ||
2086 | - erase | |
2087 | ||
2088 | This will erase the all pre-allocated buffers which are not in | |
2089 | use. | |
