Name: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.
Proto:static int xfeature_enabled(enum xfeature xfeature)
Type:int
Parameter:
| Type | Parameter | Name |
|---|---|---|
| enum xfeature | xfeature |
| 239 | Return Not Not (Mask of xstate features supported by the CPU and the kernel: & 1UL << xfeature ) |
| Name | Describe |
|---|---|
| setup_xstate_features | Record the offsets and sizes of various xstates contained* in the XSAVE state memory layout. |
| setup_xstate_comp | This function sets up offsets and sizes of all extended states in* xsave area. This supports both standard format and compacted format* of the xsave aread. |
| print_xstate_offset_size | Print out xstate component offsets and sizes |
| do_extra_xstate_size_checks | This essentially double-checks what the cpu told us about* how large the XSAVE buffer needs to be. We are recalculating* it to be safe. |
| __raw_xsave_addr | Given an xstate feature nr, calculate where in the xsave* buffer the state is. Callers should ensure that the buffer* is valid. |
