__raw_xsave_addr

Name:Given an xstate feature nr, calculate where in the xsave* buffer the state is. Callers should ensure that the buffer* is valid.

Proto:static void *__raw_xsave_addr(struct xregs_state *xsave, int xfeature_nr)

Type:void

Parameter:

Type	Parameter	Name
struct xregs_state *	xsave
int	xfeature_nr

If Not Note that in the future we will likely need a pair of* functions here: one for user xstates and the other for* system xstates. For now, they are the same. Then

Return NULL

817

Return xsave + xstate_comp_offsets[xfeature_nr]

**Caller**
Name	Describe
get_xsave_addr	Given the xsave area and a state inside, this function returns the* address of the state
copy_xstate_to_kernel	Convert from kernel XSAVES compacted format to standard format and copy* to a kernel-space ptrace buffer.* It supports partial copy but pos always starts from zero. This is called* from xstateregs_get() and there we check the CPU has XSAVES.
copy_xstate_to_user	Convert from kernel XSAVES compacted format to standard format and copy* to a user-space buffer. It supports partial copy but pos always starts from* zero. This is called from xstateregs_get() and there we check the CPU* has XSAVES.
copy_kernel_to_xstate	Convert from a ptrace standard-format kernel buffer to kernel XSAVES format* and copy to the target thread. This is called from xstateregs_set().
copy_user_to_xstate	Convert from a ptrace or sigreturn standard-format user-space buffer to* kernel XSAVES format and copy to the target thread. This is called from* xstateregs_set(), as well as potentially from the sigreturn() and* rt_sigreturn() system calls.
