. introduced DEV_READ_S, DEV_WRITE_S, DEV_SCATTER_S, DEV_GATHER_S
and DEV_IOCTL_S as replacements for DEV_READ, DEV_WRITE, DEV_SCATTER, DEV_GATHER and DEV_IOCTL. Instead of a direct address, the *_S commands pass 'grant ids' to the drivers which are referenced through a new set of copy calls (sys_safecopyfrom and sys_safecopyto). in order for this copy to succeed, the grant must have previously been created in the address space of the granter. . bitmap manipulation functions moved to <minix/bitmap.h> . HIGHPOS introduced as field containing high 32 bits of position in device I/O message; TTY_FLAGS no longer used . IO_GRANT field introduced for GRANTs, to replace ADDRESS . REP_IO_GRANT field for un-SUSPEND messages introduced to indicate grant for which I/O was done to disambiguate messages . SYS_SAFECOPYFROM and SYS_SAFECOPYTO introduced as new calls . SYS_PRIV_SET_GRANTS code introduced as a code to set the address and size of the grant table in a process' own address space . 'type' and 'direction' field of _ins* and _outs* I/O functions are merged into one by ORing _DIO_INPUT/_DIO_OUTPUT and _DIO_BYTE/_DIO_WORD etc. This allows for an additional parameter, _DIO_SAFE, which indicates the address in another address space isn't actually an address, but a grant id. Also needs an offset, for which fields had to be merged. . SCP_* are field names for SYS_SAFECOPY* functions . DIAGNOSTICS and GET_KMESS moved to their own range above DIAG_BASE, added DIAGNOSTICS_S which is a grant-based variant of DIAGNOSTICS . removed obsolete BINCOMPAT and SRCCOMPAT options . added GRANT_SEG type for use in vircopy - allows copying to a grant id (without offset) . added _MINIX_IOCTL_* macros that decode information encoded by _IO* macros in ioctl codes, used to check which grants are necessary for an ioctl . introduced the type endpoint_t for process endpoints, changed some prototypes and struct field types to match . renamed protected to prot for g++
