101 | * Workarounds for running on old versions of solaris with different cross call
|
---|
102 | * interfaces. If we find xc_init_cpu() in the kernel, then just use the
|
---|
103 | * defined interfaces for xc_call() from the include file where the xc_call()
|
---|
104 | * interfaces just takes a pointer to a ulong_t array. The array must be long
|
---|
105 | * enough to hold "ncpus" bits at runtime.
|
---|
106 |
|
---|
107 | * The reason for the hacks is that using the type "cpuset_t" is pretty much
|
---|
108 | * impossible from code built outside the Solaris source repository that wants
|
---|
109 | * to run on multiple releases of Solaris.
|
---|
110 | *
|
---|
111 | * For old style xc_call()s, 32 bit solaris and older 64 bit versions use
|
---|
112 | * "ulong_t" as cpuset_t.
|
---|
113 | *
|
---|
114 | * Later versions of 64 bit Solaris used: struct {ulong_t words[x];}
|
---|
115 | * where "x" depends on NCPU.
|
---|
116 | *
|
---|
117 | * We detect the difference in 64 bit support by checking the kernel value of
|
---|
118 | * max_cpuid, which always holds the compiled value of NCPU - 1.
|
---|
119 | *
|
---|
120 | * If Solaris increases NCPU to more than 256, VBox will continue to work on
|
---|
121 | * all versions of Solaris as long as the number of installed CPUs in the
|
---|
122 | * machine is <= IPRT_SOLARIS_NCPUS. If IPRT_SOLARIS_NCPUS is increased, this
|
---|
123 | * code has to be re-written some to provide compatibility with older Solaris
|
---|
124 | * which expects cpuset_t to be based on NCPU==256 -- or we discontinue
|
---|
125 | * support of old Nevada/S10.
