-script argument to service for crash recovery scripts
-config argument to service for driver resource configuration
restart command in service to restart a driver after a crash (for use in
crash recovery scripts).
down and refresh now take labels instead of pids.
verious changes in rs to make this work.
size field. The TIOCSFON ioctl size (8192) didn't get encoded properly,
as there weren't enough bits for it (12) in the regular format.
The new format has only one type field, and an extra flag (_IOC_BIG)
turned on. FS checks for this flag and uses the alternative decoding
of the ioctl codes to determine the size when doing grants.
This unbreaks loadfont, although that still uses a phys copy in tty.
form. Subscriptions are regular expressions.
. different types are stored per key; currently u32 and/or string.
the same key can be referenced (publish, subscribe, check) as any type.
. notify()s are sent when subscriptions are triggered (publishing or
updating of matching keys); optionally, a subscribe flag sends
updates for all matching keys at subscription time, instead of only
after updates after subscribing
. all interfacing to ds is in /usr/src/lib/syslib/ds.c.
. subscribe is ds_subscribe
publish functions are ds_publish_<type>
retrieve functions are ds_retrieve_<type> (one-time retrieval of a value)
check functions are ds_check_<type> (check for updated key caller
subscribes to not yet checked for, or ESRCH for none)
. ramdisk driver updated with new ds interface
Safecopies renders the NWIOQUERYPARAM ioctl useless. This functionality
is now replaced with /dev/ipstat. Write the request to the device and
read the answer in one read request.
Added BUSC_PCI_DEV_NAME_S and BUSC_PCI_SLOT_NAME_S to support safecopies in PCI.
Added DL_WRITEV_S, DL_READV_S, DL_GETSTAT_S, DL_GRANT, and iovec_s_t to support
safecopies in ethernet drviers. Renamed DL_INIT to DL_CONF, and DL_INIT_REPLY
to DL_CONF_REPLY.
Added SYS_READBIOS and sys_readbios to read from BIOS data areas.
Added GET_KMESS_S for safecopy support in LOG.
Added sys_safe_insb and sys_safe_outsb.
. changed some CMOS ioctl codes to have correct sizes (struct tm instead
of u32_t), a disk ioctl code from W to RW, and memory ioctl codes from R
to W, needed for proper matching of grant in FS
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++
library to the memory driver. Always put output from within TTY directly on
the console. Removed second include of driver.h from tty.c. Made tty_inrepcode
bigger. First step to move PM and FS calls that are not regular (API)
system calls out of callnr.h (renumbered them, and removed them from the
table.c files). Imported the Minix-vmd uname implementation. This provides
a more stable ABI than the current implementation. Added a bit of security
checking. Unfortunately not nearly enough to get a secure system. Fixed a
bug related to the sizes of the programs in the image (in PM patch_mem_chunks).
