config ARCH default "x86_64" config XUK_DEBUG bool "Debug logging at lowest level" help When true, enables debug logging from the XUK layer in very early boot situations (including the 16 and 32 bit stub code) on the first serial port (115200 8n1) and VGA text console. Also wires that output stream to the printk() function so it can be used before any console drivers are initialized. config XUK_APIC_TSC_SHIFT int "Power-of-two divisor between TSC and APIC timer" default 6 help Configures the precision of the APIC timer as a bit shift of the TSC frequency. High values "slow down" the tick rate of the APIC timer and allow for longer timeouts at the expense of precision. config IRQ_OFFLOAD_VECTOR int "Interrupt vector for irq_offload" default 255 help This is the interrupt vector to use for the self-directed IPIs used to implement irq_offload(). Most apps will never change this. It's configurable in case someone wants to play with its priority.
