* | fix breakage from introducing bits header for sys/io.h | Rich Felker | 2012-11-18 | 1 | -0/+3 |
| | | | | | | apparently some other archs have sys/io.h and should not break just because they don't have the x86 port io functions. provide a blank bits/io.h everywhere for now. | ||||
* | add port io functions to sys/io.h | Rich Felker | 2012-11-18 | 1 | -2/+3 |
| | | | | | | | based on proposal by Isaac Dunham. nonexistance of bits/io.h will cause inclusion of sys/io.h to produce an error on archs that are not supposed to have it. this is probably the desired behavior, but the error message may be a bit unusual. | ||||
* | add ioperm/iopl syscalls | Rich Felker | 2012-07-23 | 1 | -0/+13 |
based on patches by orc and Isaac Dunham, with some fixes. sys/io.h exists and contains prototypes for these functions regardless of whether the target arch has them; this is a bit unorthodox but I don't think it will break anything. the function definitions do not exist unless the appropriate SYS_* syscall number macro is defined, which should make sure configure scripts looking for these functions don't find them on other systems. presently, sys/io.h does not have the inb/outb/etc. port io macros/functions. I'd be surprised if ioperm/iopl are useful without them, so they probably need to be added at some point in appropriate bits/io.h files... |
