manu f464631d66 Several things:
1) rights should be shared by the threads within a process. While it would
be easier to handle this with the struct proc/struct lwp split, we attempt to
do this now by sharing the right lists. Because each right holds a reference
to struct proc, this might cause some problems later.
2) in pthread_exit, really exit the thread. Also reintialize the righ tlist to
make sure we will not destroy the parent's right list
3) rights can hold multiple permissions on a port (ie: send and receive). Fix th
is.
4) first attempt on right carried by messages. We still have to do rights carrie
d in the message body (complex messages).

manu 4a06119a9d Pass the system call table to trace_enter() and ktrsys() so that it is
possible to use alternate system call tables. This is usefull for
displaying correctly the arguments in Mach binaries traces.

If NULL is given, then the regular systam call table for the process is used.

scw 4e87eae834 Use Software Single Stepping for now when PPC_IBM4xx is defined. The
existing hardware assisted method doesn't work on this cpu.

Also correct the "I_B" constant in db_machine.h.

thorpej 2a39e8388d Merge the IBM 4xx into the common powerpc/locore_subr.S, and
eliminate all the duplicated context switch related code in
the IBM 4xx port.

scw c10c20ac28 Add a range check for the DCR address in db_ppc4xx_dcr(). 2002-12-19 13:45:03 +00:00
scw de98ba0a49 Add a "machine dcr" command, for the IBM4XX case, which permits
reading/writing of the cpu's DCR registers.

manu 98bc8767ae Bug fixes:
- In case of ailure in the child, kill the child and wakeup the parent
- Do call child_return
- The src and dst args were mixed up when copying regs 0-31 to the trapframe

This makes pthread_create(3) fully working (test program works).

manu 66a29c52af Added a few Mach traps: mach_boostrap_register, mach_port_set_attributes,
mach_port_move_member, mach_port_set_attributes, mach_task_set_special_port,
(none do anything)
Added mach_thread_create_running, which creates a new Mach thread. It
provides the register context of the new thread. We use it in a child
function provided to fork1(). The child function is machine dependent and
is not yet implemented for i386.

The new thread crashes quickly, but at least it starts.

thorpej e8cc3884de Rename __LDPGSZ to AOUT_LDPGSZ, to accurately reflect what it is. 2002-12-10 17:14:02 +00:00
thorpej 78ea2dd367 Use __LDPGSZ (which must be == USRTEXT) as the text address for a.out
executables, and eliminate the USRTEXT constant, which was only used
by the a.out exec code.

manu 9f6565f2bd A working fork/vfork implementation. Darwin fork differs from our fork by
two ways:
- the child gets its pid as retval[0] (userland stub will turn it into a 0),
retval[1] is 1 and it is 0 in the parent.
- in the child, the fork syscall is successful, hence we must skip the next
instruction.

manu 3b0f6d78ed Introduce BSD system calls with alternate patch checking (in /emul) in
compat/common, so that they can be shared by several emulations, and use
them for Darwin.

This removes the ugly dependance on FreeBSD freebsd_file.c for COMPAT_DARWIN

thorpej a13469e728 Revert my previous GCC 3.3-related changes; GCC 3.3 has been fixed
to handle our stdarg/varargs ABI for PowerPC.

manu a9a3da8aca The recent mach trap support caused indirect system calls (a la syscall(2))
to be incorectly recorded as 'syscall'. Fix this.

manu 508a5615a6 Build the beast again after siginfo changes 2002-11-29 00:04:03 +00:00
manu dfa96ff4b3 Add signal delivery for the PowerPC. Everything is implemented except siginfo.
The stack layout is observed from stack dumps on Darwin, so it should be
very accurate.

manu edff1c8d0a There is too much debugging, it's getting annoying. Let's remove some. 2002-11-26 23:48:44 +00:00
lukem 0635de35a3 Remove KDIR=, since SYS_INCLUDE=symlinks and KDIR are not supported any more. 2002-11-26 23:30:07 +00:00
manu 53356d6169 Added an empty shell for signal delivery. Now we just have to fill the
machine dependant bits.

manu e7cfdc3995 Darwin skips the next instruction after a successful system call. Strange
world.

manu 3fc8f36b8d Make it build again 2002-11-15 21:48:06 +00:00
manu d584ed9598 Add a realcode argument to trace_enter and ktrsyscall. realcode is the
original system call number, which can be negative for a Mach trap.
We cannot just replace code by realcode, because ktrsyscall uses it as
an index in the system call table, thus crashing the kernel when the
value is negative.

matt da584e2f99 If MULTIPROCESSOR, just accept the penalties of doing BAT flipping when
syncing the icache.
2002-11-13 21:08:50 +00:00
matt 3a5d673363 Change syscall to bound code so that systrace and ktrace won't fall off
the end of a table.   XXX this is wrong since code does not indicate the
sysent table for which code was used as an index.

matt 9cf475322b Do kernel non-USER_SR pte spilling regardless of interrupt count. Only do
kernel USER_SR spillage if interrupt depth is 0.

jdolecek 2ba45545df back previous off; don't install macho_machdep.h 2002-11-04 15:27:15 +00:00
matt 85529376d3 Get rid of nsysent. Use EMULNAMEU to use the appropriate constant.
Revamp the mach_syscall_dispatch function to be much simplier (pass in
a syscall code and return a const struct sysent * pointer).
2002-11-04 00:01:02 +00:00
manu 873ed6f9ee Added support for Darwin's PowerPC-only system calls:
ppccalls, with system call numbers starting at 0x6000
fasttraps, with system call numbers starting at 0x7FF0

Because the Mach system call dispatching code has grown a bit
too much, introduce an inline function to handle it (mach_syscall_dispatch).

While we are there, remove the Mach and Linux includes from
arch/powerpc/powerpc/syscall.c and push them into
arch/powerpc/powerpc/{mach|linux}_syscall.c
