Make it possible to move a device to its unconfigured state by
using config #0.
Add some comments.
Change error reporting in port reset function.
usbd_devinfo_vp(): search the know devs array also if the device doesn't
return product description (e.g. Kye's Genius NetScroll mouse returns
vendor, but not product); the strings returned by device are still
preferred to those in the array, though
SUPFLAGS when a 'make update' is run. This means that the supfile
doesn't need to be edited because the -h will override the
CHANGE_THIS.FreeBSD.org host.
ENABLE_SUIDPERL is set to true. When perl is updated to remove the
fork mail code, additional warnings will enable the users to know what
is gonig on and how to correct it. Markm will make those commits as
part of his perl patch integration. suidperl is installed with
execute permissions so that markm's added error messages wil be seen
by the user.
flag has been depricated, although it still works with a warning
message, and replaced with an environment variable CLICOLOR (command
line interface colour). This could be used by other tools that
want to be able to control colour output.
In addition if the environment variable CLICOLOR_FORCE is defined
colour sequences are output irrespective of whether the output is
directed to a terminal (as long as TERM references a colour capable
terminal of course ;)
PR: bin/20291 and bin/20483
Beyond changes to the build system, this includes fixing up the sample
freebsd.mc configuration for changes in defaults and syntax, removing
outdated documentation, and updating the release notes.
LDFLAGS instead of to LDADD, so they ended up too early in the command
line.
Don't link to libcrypt. It is unused for static linkage and unnecessary
and only apparently used for dynamic linkage (the dynamic libskey is
linked to libcrypt to support the crypt parts of libskey which aren't
used here).
Fixed some disorder.
Clean up some low level bootstrap code:
- stop using the evil 'struct trapframe' argument for mi_startup()
(formerly main()). There are much better ways of doing it.
- do not use prepare_usermode() - setregs() in execve() will do it
all for us as long as the p_md.md_regs pointer is set. (which is
now done in machdep.c rather than init_main.c. The Alpha port did it
this way all along and is much cleaner).
- collect all the magic %cr0 etc register settings into one place and
have the AP's call that instead of using magic numbers (!!) that keep
changing over and over again.
- Make it safe to call kthread_create() earlier, including during the
device probe sequence. It doesn't need the callback mechanism that
NetBSD's version uses.
- kthreads created this way are root-less as they exist before the root
filesystem is mounted. init(1) is set up so that it aquires the root
pointers prior to running. If other kthreads want filesystem acccess
we can make this code more generic.
- set all threads start times once we have decided what time it is.
- init uses a trampoline rather than the evil prepare_usermode() hack.
- kern_descrip.c has a couple of tweaks to deal with forking when there
is no rootdir or cwd etc.
- adjust the early SYSINIT() sequence so that a few prereqisites are in
place. eg: make sure the run queue is initialized before doing forks.
With this, the USB code can easily create a kthread to do the device
tree discovery. (I have tested it, it works nicely).
There are still some open issues before this is truely useful.
- tsleep() does not like working before the clock is running. It
sort-of tries to spin wait, but it can do more useful things now.
- stopping a kthread in kld code at unload time is "interesting" but
we have a solution for that.
The Alpha code needs no changes for this. It already uses pretty much the
same strategies, but a little cleaner.
