Name:mds_select_mitigation
Proto:static void __init mds_select_mitigation(void)
Type:void
Parameter:Nothing
| 240 | If Not boot_cpu_has_bug(CPU is affected by Microarchitectural data sampling ) || cpu_mitigations_off() Then |
| 242 | Return |
| 245 | If Default mitigation for MDS-affected CPUs == MDS_MITIGATION_FULL Then |
| 246 | If Not boot_cpu_has(VERW clears CPU buffers ) Then Default mitigation for MDS-affected CPUs = MDS_MITIGATION_VMWERV |
| 249 | Normal usage; boolean enable/disable.( & Control MDS CPU buffer clear before returning to user space ) |
| 251 | If Not boot_cpu_has(CPU is only affected by the MSDBS variant of BUG_MDS ) && (mds_nosmt || cpu_mitigations_auto_nosmt()) Then cpu_smt_disable(false) |
