Here are some patches for FreeBSD's kernel that are necessary for wine
|
|
(well not strictly _necessary_ but without them parts of it won't work.)
|
|
They unfortunately didn't make it into the base distribution in time
|
|
for the 3.3 release code freeze...
|
|
|
|
patch-3.3-sys-ldtshare:
|
|
make kernel threads (rfork(), which wine uses) share one LDT instead of
|
|
each having its own. this fixes the same problem that wine also had on
|
|
linux kernels before 2.2.
|
|
|
|
patch-3.3-sys-sigtrap:
|
|
stop wine's SIGTRAP handler from being called in the sigreturn syscall,
|
|
causing problems for wine's internal debugger. (it would still
|
|
correctly show a crash backtrace but all commands that use single-
|
|
stepping failed.)
|
|
|
|
patch-3.3-sys-fsgs:
|
|
always set/use the sc_fs and sc_gs entries in the sigcontext struct,
|
|
making -stable behave the same as -current there. this should finally
|
|
allow signal handling of a wine that was built on -stable to correctly
|
|
run on -current too. The corresponding wine change is in the port in
|
|
patches/patch-af, it is also in wine's CVS tree now, so that file will
|
|
disappear when the port is updated after the next wine release.
|
|
(this one was MFC'd Nov 15 1999, so you only need it if you're running a
|
|
system from the -stable branch older than that, like a 3.3-RELEASE. If you
|
|
happen to try to apply it when its already there patch(1) should complain
|
|
`Reversed (or previously applied) patch detected! Assume -R? [y]',
|
|
just hit ^C then...)
|
|
|
|
Apply as follows:
|
|
|
|
(cd /usr/src/sys && patch ) <patch-3.3-sys-ldtshare
|
|
(cd /usr/src/sys && patch ) <patch-3.3-sys-sigtrap
|
|
|
|
And if you don't already have it:
|
|
|
|
(cd /usr/src/sys && patch ) <patch-3.3-sys-fsgs
|
|
|
|
then build a new kernel. (don't forget to include the options USER_LDT,
|
|
SYSVSHM, SYSVSEM, and SYSVMSG, wine needs these.)
|
|
|
|
A note about local patches and ctm, cvsup and friends...
|
|
(if you don't know what those are good for see for example
|
|
http://www.freebsd.org/handbook/stable.html)
|
|
ctm cannot deal with local patches (unless you use it to mirror
|
|
the cvs tree of course, instead of the sources directly), with
|
|
cvsup i'm not sure but in any case the workaround is simple: use
|
|
patch -R to un-apply any local patches before the update (feeding
|
|
it the patches again as above on stdin), then when the update is
|
|
finished apply them again. Should they fail on the updated sources
|
|
(and you cannot fix it yourself), look for new versions of the
|
|
patches at the place where you got them, or in this case you
|
|
can also look in my current wine port tree at
|
|
http://www.jelal.kn-bremen.de/freebsd/ports/emulators/wine/files/
|
|
|
|
-current users:
|
|
A LDT patch for -current is at http://people.FreeBSD.org/~luoqi/
|
|
(well in a recent posting on the -current list,
|
|
http://www.freebsd.org/cgi/mid.cgi?db=&id=199911150745.CAA27884@lor.watermarkgroup.com
|
|
he said that version is outdated, seems you have to mail him to
|
|
get a current one), the sigtrap patch looks like it could also
|
|
apply to -current but i haven't tried. And the fs/gs patch of course
|
|
already is in -current.
|
|
Late note: the LDT sharing fix just seems to have been committed now...
|
|
(to -current that is.)
