CONFIG_IOAPIC_NUM_RTES
¶
Number of Redirection Table Entries available
Type: int
Help¶
This option indicates the maximum number of Redirection Table Entries (RTEs) (one per IRQ available to the IO-APIC) made available to the kernel, regardless of the number provided by the hardware itself. For most efficient usage of memory, it should match the number of IRQ lines needed by devices connected to the IO-APIC.
Default¶
24
