What's new in QNX Neutrino Core OS 6.3.2

New content

aps: Manage adaptive scheduler partitions

Changed content

devb-ram

Added address, blksize, and nodinit to the list of ram options.

mkifs

Now includes the module attribute for loading optional modules into procnto.

on

Now includes -C, -i, and -R options for specifying the runmask for the new process.

pidin

Now includes H, h, i, and o formatting codes, and extsched, fds, regs, sched, and threads arguments.

procnto

Now includes -m and -c options.

slay

Now includes -C, -i, and -R options for manipulating the runmask, and -T for identifying the thread that you want to send a signal to or whose runmask or priority you want to change. Also includes -m option to restrict the match.

-P without -T now affects all threads in the specified proccess or processes. Previously it affected only thread 1.

This utility now matches process IDs or names; you can use the new -m option to limit which it matches.

startup-*

Now include a -F option to control the flags field in the cpuinfo section of the system page.

qconfig

Added the -a, -b, and -p options.

Errata

dcheck: Corrected the name of the .bad_blks file.
passwd: The second field of entries in the /etc/passwd file is an x. It represents the group password, which Neutrino doesn't support.
psin: A suffix of s appears beside file descriptors that were opened as side channels.

What's new in 6.3.0 Service Pack 2

qcc: The -M option is deprecated as of QNX Momentics 6.3.0 Service Pack 2. The next release will use -M for generating Makefile dependencies.
The -w9 option's behavior specifically documented, with additional options necessary to report all warnings.
qconn: Added more description to the qconn_prio= option to prevent errors when the system is under heavy load.
sendnto: Documented -b option.
su: Documented - userid argument.

usemsg also uses objcopy by default instead of ldrel.

Errata

io-blk.so: If you don't specify a full path for the device in the automount option, io-blk.so uses the value of its devdir option as a prefix.
