* MAXVINTRS is the number of interrupts we require to be allocated
* in the system intr_vec_table in addition to the hardware interrupts.
* These interrupts will be used by the sun4v cnex driver for its Logical
* Domain Channels. Each LDC requires a pair of interrupts, (RX/TX),
* and the total number of interrupts required will depend on the
* resources available to the system (CPUs, memory, etc) and how
* the system domains are configured, (number of virtual disks/networks
* per domain etc).
*
* The service domain requires (at least) a console LDC, Domain Services
* LDCs, vdisk LDC and vnet LDC per guest domain. It also requires a small
* number of LDCs for communications with the SP etc.
*
* The number of LDCs required is ~(N * 4 + a few more) where N is the
* possible maximum guest domains. The current possible maximum
* number of domains is 512, so we require ~2048 LDCs. And as
* each LDC requires a pair of interrupts we need to add the
* capacity for ~4096 interrupts to the system interrupt table.
*
* We start allocating the LDC interrupts at MINVINTR_COOKIE.
