| |
The i810 driver contains a direct wbinvd invocations in the form: asm volatile ("wbinvd":::"memory")
Replace this call with the kernel API "native_wbinvd()" that translates to same as "asm volatile("wbinvd" : : : "memory")" and provides a central location where calls to this destructive instruction can be tracked and potentially acted on.
