To gain this access the caller needs CAP_SYS_RAWIO 1267 capabilities and permission from potentially active security 1268 modules. 1269 1270 The emulation restricts the functionality of the syscall to 1271 only allowing the full range I/O port access, but prevents the 1272 ability to disable interrupts from user space which would be 1273 granted if the hardware IOPL mechanism would be used. 1274 | |
