with zoneinfo implementations in src/commands/zoneinfo, referenced
from src/lib/stdtime/Makefile.in.
. read_tsc() in sysutil library saves edx and eax now
. added read_tsc_64() by Antonio Mancina to load tsc into
a 64-bit data type directly
. deleted read_tsc.h in favour of a prototype in <minix/syslib.h>
us killed through the kernel with PM finding out.
This makes it unnecessary for servers and drivers to be able to do
sys_kill generally, so KILL can go out of /etc/drivers.conf.
. pci_reserve() returns an error on devices that have already been reserved,
instead of panic()ing; the pci_reserve() library call still panics,
pci_reserve_ok() returns an int.
. this allows at_wini to use the instance value as intended, as all devices
are seen, even reserved ones
. only devices actually used by at_wini are pci_reserve()d
. pci doesn't release devices based on argv[0], as at_wini both have the
same name and multiple instances won't work together properly
. changed umount() and mount() to call 'service', so that it can include
a custom label, so that umount() works again (RS slot gets freed now).
merged umount() and mount() into one file to encode keep this label
knowledge in one file.
. removed obsolete RS_PID field and RS_RESCUE rescue command
. added label to RS_START struct
. vfs no longer does kill of fs process on unmount (which was failing
due to RS_PID request not working)
. don't assume that if error wasn't one of three errors, that no error
occured in vfs/request.c
mfs changes:
. added checks to copy statements to truncate copies at buffer sizes
(left in debug code for now)
. added checks for null-terminatedness, if less than NAME_MAX was copied
. added checks for copy function success
is changes:
. dump rs label
drivers.conf changes:
. added acl for mfs so that mfs can be started with 'service start',
so that a custom label can be provided
mainly in the kernel and headers. This split based on work by
Ingmar Alting <iaalting@cs.vu.nl> done for his Minix PowerPC architecture
port.
. kernel does not program the interrupt controller directly, do any
other architecture-dependent operations, or contain assembly any more,
but uses architecture-dependent functions in arch/$(ARCH)/.
. architecture-dependent constants and types defined in arch/$(ARCH)/include.
. <ibm/portio.h> moved to <minix/portio.h>, as they have become, for now,
architecture-independent functions.
. int86, sdevio, readbios, and iopenable are now i386-specific kernel calls
and live in arch/i386/do_* now.
. i386 arch now supports even less 86 code; e.g. mpx86.s and klib86.s have
gone, and 'machine.protected' is gone (and always taken to be 1 in i386).
If 86 support is to return, it should be a new architecture.
. prototypes for the architecture-dependent functions defined in
kernel/arch/$(ARCH)/*.c but used in kernel/ are in kernel/proto.h
. /etc/make.conf included in makefiles and shell scripts that need to
know the building architecture; it defines ARCH=<arch>, currently only
i386.
. some basic per-architecture build support outside of the kernel (lib)
. in clock.c, only dequeue a process if it was ready
. fixes for new include files
files deleted:
. mpx/klib.s - only for choosing between mpx/klib86 and -386
. klib86.s - only for 86
i386-specific files files moved (or arch-dependent stuff moved) to arch/i386/:
. mpx386.s (entry point)
. klib386.s
. sconst.h
. exception.c
. protect.c
. protect.h
. i8269.c
-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.
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
. added safecopies.c:
these are library functions to maintain grant tables in own address space
. sys_safecopy.c:
interfaces to kernel calls to perform safe copy functions in from or to
foreign process
. changes in i/o fields (type merged with request) reflected in
library functions (sys_out.c, sys_vinb.c, sys_vinl.c, sys_vinw.c,
sys_voutb.c, sys_voutl.c, sys_voutw.c)
. type merged with request in sys_sdevio, also now accepts offset which
is used when a grant is specified (the _DIO_SAFE subtype)
. system printf() function changed to send DIAGNOSTICS_S messages, which
specify a grant id instead of a direct address for the buffer to be
printed; tty and log can then safecopy the buffer
