General informations

The Linux kernel configuration item CONFIG_FT_NR_BUFFERS:

Help text

Please leave this at `3' unless you REALLY know what you are doing. It is not necessary to change this value. Values below 3 make the proper use of ftape impossible, values greater than 3 are a waste of memory. You can change the amount of DMA memory used by ftape at runtime with "mt -f /dev/qft0 setdrvbuffer #NUMBUFFERS". Each buffer wastes 32 KB of memory. Please note that this memory cannot be swapped out.
