shared FreeBSD binaries coredump.
This solves port-i386/11708 by Atsushi Onoe.
XXX it may be worth it to split FreeBSD syscall code off syscall.c similar way
XXX as other emulations
GENERIC is the kernel used on new installs and too many things overlap the
resources (irq mostly) the default isa version may be using which causes
panics on reboot.
returns for floppy controllers i/o ports. i.e.
1. 1 range of length 4 (which conveniently "forgets" the ctl i/o port),
2. 2 ranges: 1 of length 4 and the ctl i/o port.
3. 1 range of length 6 which goes to the end of the ctl i/o.
Make this line up with the MI fdc code by mapping in a range of 4 on the
base i/o and then either direct or submapping the ctl i/o. In the one case
where the BIOS lies and says it's not there just map it in anyways. (but note
the fact to the end user).
This is very adhoc work for IETF meeting.
- Since it seems that 'an' and 'wi' have similar hardware, low level
functions should be shared.
- There are PCI/ISA cards of Aironet but not supported yet.
- The wiconfig interface is changed so that wiconfig cannot be used.
- 'ancontrol' of FreeBSD is not ported.
- Only infrastructure mode is tested.
- WEP is not supported.
Though I only have an Aironet card, Cisco card should be expected to work.
* __HAVE_SYSCALL_INTERN. If this is defined, e_syscall is replaced by
e_syscall_intern, which is called at key places in the kernel. This can be
used to set a MD syscall handler pointer. This obsoletes and replaces the
*_HAS_SEPARATED_SYSCALL flags.
* __HAVE_MINIMAL_EMUL. If this is defined, certain (deprecated) elements in
struct emul are omitted.
defined, call addupc_intr() directly from statclock() in the system time case,
using the same P_OWEUPC path if the copyin/copyout fails.
Use this in i386 to remove profiling code from the normal userret() path.
this should improve speed of emulation syscall path (avoids one function call,
and emulations syscall can use the trapframe trick)
Idea: Charles Hannum
Remove the EMUL_HAS_SYS___syscall test, because the handler is no longer shared
with SVR4.
Rather than comparing with e_nsysent, just mask the value. This is only done
to protect us from malicious programs anyway.
Also, there is no reason to save the original PC; there are no restartable
syscalls that change the PC -- and even if there were, they wouldn't do it
in the restart case.
