65c72795ab90d3daefa759b716fbb5c6352c7a56vboxsync * Workarounds for running on old versions of solaris with different cross call
65c72795ab90d3daefa759b716fbb5c6352c7a56vboxsync * interfaces. If we find xc_init_cpu() in the kernel, then just use the
65c72795ab90d3daefa759b716fbb5c6352c7a56vboxsync * defined interfaces for xc_call() from the include file where the xc_call()
65c72795ab90d3daefa759b716fbb5c6352c7a56vboxsync * interfaces just takes a pointer to a ulong_t array. The array must be long
65c72795ab90d3daefa759b716fbb5c6352c7a56vboxsync * enough to hold "ncpus" bits at runtime.
65c72795ab90d3daefa759b716fbb5c6352c7a56vboxsync * The reason for the hacks is that using the type "cpuset_t" is pretty much
65c72795ab90d3daefa759b716fbb5c6352c7a56vboxsync * impossible from code built outside the Solaris source repository that wants
65c72795ab90d3daefa759b716fbb5c6352c7a56vboxsync * to run on multiple releases of Solaris.
65c72795ab90d3daefa759b716fbb5c6352c7a56vboxsync * For old style xc_call()s, 32 bit solaris and older 64 bit versions use
65c72795ab90d3daefa759b716fbb5c6352c7a56vboxsync * "ulong_t" as cpuset_t.
65c72795ab90d3daefa759b716fbb5c6352c7a56vboxsync * Later versions of 64 bit Solaris used: struct {ulong_t words[x];}
65c72795ab90d3daefa759b716fbb5c6352c7a56vboxsync * where "x" depends on NCPU.
65c72795ab90d3daefa759b716fbb5c6352c7a56vboxsync * We detect the difference in 64 bit support by checking the kernel value of
65c72795ab90d3daefa759b716fbb5c6352c7a56vboxsync * max_cpuid, which always holds the compiled value of NCPU - 1.
65c72795ab90d3daefa759b716fbb5c6352c7a56vboxsync * If Solaris increases NCPU to more than 256, VBox will continue to work on
65c72795ab90d3daefa759b716fbb5c6352c7a56vboxsync * all versions of Solaris as long as the number of installed CPUs in the
65c72795ab90d3daefa759b716fbb5c6352c7a56vboxsync * machine is <= IPRT_SOLARIS_NCPUS. If IPRT_SOLARIS_NCPUS is increased, this
65c72795ab90d3daefa759b716fbb5c6352c7a56vboxsync * code has to be re-written some to provide compatibility with older Solaris
65c72795ab90d3daefa759b716fbb5c6352c7a56vboxsync * which expects cpuset_t to be based on NCPU==256 -- or we discontinue
65c72795ab90d3daefa759b716fbb5c6352c7a56vboxsync * support of old Nevada/S10.
