Hi,
I am seaching for API in IOKit which provides non
blocking memory allocation functionallity.
But I think IOkit has only IOMalloc one,
is there any non blocking api available through i can
allocate memory, when i held the spin lock?
I searched the xnu code and there was one called
zalloc_noblock()
header : /osfmk/kern/zalloc.h
but it uses some zone ...
is it the one which i should use?
if yes any idea how to use this zone in the code?
Can i use it at IOkit driver level?
any sample availble or this is for xnu kernel only?
Regards,
Parav Pandit
