WebWhen a Prefetch Abort (PABT) occurs, the processor marks the prefetched instruction as invalid, but does not take the exception until the instruction is to be executed. If the instruction is not executed, for example because a branch occurs while it is in the pipeline, the abort does not take place. All prefetch aborts are precise.

The CPU requires a fixed number of clock ticks (or clock cycles) to execute each instruction. The faster the clock, the more instructions the CPU can execute per second.

WebOn startup, the kernel will initialize an interrupt vector table (called an interrupt descriptor table or IDT on x86) that points to an interrupt handler for each line..

This allows firmware first handling for possible SEA (Synchronous External Abort) caused instruction abort at current EL. Signed-off-by: Tyler Baicar Signed-off-by: Naveen Kaje --- WebA Prefetch Abort exception can be generated by: A synchronous memory abort on an instruction fetch.
