[Bug 183456] Re: Trying to load a sf2 file with asfxload returns "sfxload: no memory left"

Can't anyone pick this up?  Please?  I have had this problem for years
now, ever since I upped my RAM.  I would love to use my emu10k1 synth
chip again since it is less laggy than any software synth.

I was told that this problem is due to the EMU10k1 being unable to
address more than 2G of memory.  That is why the emu10k1 driver can load
a soundfont when the system has 2G, but not when it has more.  I had 4G
and now 6G and so I have this issue.

It appears that the solution would be to modify the emu10k1 driver so it
allocates its soundfont cache within the lowest 2G of RAM.  I believe
the allocation is done in emu10k1_main.c, and it is currently done by
vmalloc.  I have read of references to a DMA32 flag that is often used
to fix similar problems with other old sound cards.

Comments?
