Bug ID: 274316
Summary: excessive memory consumed by static_single_cpu_mask
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
in sys/compat/linuxkpi/common/src/linux_compat.c we have:
static cpumask_t static_single_cpu_mask[MAXCPU];
cpumask_t *
lkpi_get_static_single_cpu_mask(int cpuid)
{
KASSERT((cpuid >= 0 && cpuid < MAXCPU), ("%s: invalid cpuid %d\n",
__func__, cpuid));
return (&static_single_cpu_mask[cpuid]);
}
when testing (an admittedly excessive) MAXCPU=65536 this array is huge (as
cpumask_t also scales with MAXCPU). on arm64 andrew found it is responsible for
512M of .bss's 566M.
