libkernel exported scePthreadAttrSetschedpolicy and
scePthreadAttrSetinheritsched but not the matching getters,
scePthreadAttrGetschedpolicy (NID NMyIQ9WgWbU) and
scePthreadAttrGetinheritsched (NID lpMP8HhkBbg), so a title that
imports either one stopped at startup on the unresolved import. Dragon
Ball Xenoverse 2 (PPSA08587) imports both.
Implement them as FreeBSD 11.4 libthr implements
pthread_attr_getschedpolicy and pthread_attr_getinheritsched
(lib/libthr/thread/thr_attr.c): a null or uninitialized attribute
returns EINVAL (0x80020016), as does a null output of
scePthreadAttrGetschedpolicy; otherwise the attribute's policy or
inheritance is stored and 0 is returned. libthr writes through a null
output of the inheritance getter unchecked, so that case throws, as
pthread_attr_getinheritsched and scePthreadAttrGetsolosched do.
Neither getter was measured on a console. The scePthreadAttr entry in
docs/dev/debt/libkernel.md, which describes the calls measured on a
PS5, now says so and records the throw.

On a PS5 (firmware 13.60) the scePthreadAttr setters and getters return
EINVAL for a null or uninitialized attribute and for a null output,
ENOTSUP for a policy other than SCHED_FIFO and SCHED_RR, an inheritance
other than explicit and inherit, and a priority outside 256 to 767, and
EINVAL for an invalid detach state. Here they threw, or stored any
policy, inheritance and priority.
