函数名称: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.
函数原型:static void __init setup_xstate_comp(void)
返回类型:void
参数:无
356 | xstate_comp_offsets[XFEATURE_FP]等于0 |
357 | xstate_comp_offsets[XFEATURE_SSE]等于offsetof(structfxregs_state, xmm_space) |
360 | 如果非boot_cpu_has(XSAVES/XRSTORS instructions )则 |
361 | 以i小于XFEATURE_MAX循环 |
363 | xstate_comp_offsets[i]等于xstate_offsets[i] |
364 | xstate_comp_sizes[i]等于xstate_sizes[i] |
367 | 返回 |
373 | 以i小于XFEATURE_MAX循环 |
374 | 如果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.则xstate_comp_sizes[i]等于xstate_sizes[i] |
376 | 否则xstate_comp_sizes[i]等于0 |
379 | 如果i大于FIRST_EXTENDED_XFEATURE则 |
