Hello,
We have some dedicated interface for connecting various external
devices (NOR, ONENAND, SMSC network adapter), similar to PCI except
one big difference/restriction:
we can not work in atomic context because low lever drivers have such
limitation.
I would like to write network driver (for SMSC chip for example) with
this restriction.
Do we have some network driver which also have suffer from similar restrictions?
Thanks in advance
Mile

USB network drivers are probably dealing with similar restrictions
(no synchronous access to device registers).
