I know that the interrupts
are divided into maskable and non-maskable interrupts. and what i want to know
:
1- is enabling/disabling interrupts the same as masking/unmasking interrupts? and what is the differences in case not ? 2- can non-maskable interrupts be disabled (in the case that the two operations (disable/mask) are not the same) ? 3- how can disabled interrupts be unlost ?? and how do the PIC sends them again to the CPU as they are enabled again ? 4- are masked interrupts lost ? or they are to be send again when they are unmasked ? By the way i'm reading
"understanding the linux kernel 2nd edition" so who has the book can know what
the information are missing to me
thanks in
advance.
