sommerfeld b10656ba32 Delete dead code.
Mask segment registers from trap frame with 0xffff for cleanliness.
2001-06-18 03:33:59 +00:00
sommerfeld 926b6ff132 since seg regs are 16 bits, toss high order bits from the trapframe 2001-06-18 03:32:14 +00:00
christos 59abdecf4b Add a linux specific trapsignal() function. This is just a passthrough
on all platforms but the i386. On the i386 we look at T_PROTFLT and send
a SIGSEGV instead of SIGBUS. This makes allegro lisp 5.0 and pvs (a proof
verification system) to work.

XXX[1]: We need to go through each architecture and verify that we send
        the correct signal on each trap type.
XXX[2]: trap.c on all other architectures but i386 needs to be modified
        to s/trapsignal/(*p->p_emul->e_trapsignal)/g
2001-06-18 02:04:42 +00:00
christos 0f380fac15 Add an e_trapsignal member to struct emul, so that emulated processes can
send the appropriate signal depending on the trap type.

sommerfeld 7e7d262c34 Add %fs/%gs to trap frame and save/restore them on
trap/interrupt/syscall entry from userspace.

Remove special-case "by hand" validation of fs/gs register values as
well as special handling of them in various signal handling paths.

Now, like %ds and %es, they are validated by the hardware on return to
userland.

This paves the way for the use of %fs for per-cpu data on
multiprocessor systems, and fixes an otherwise difficult-to-fix
interaction between threads/clone(2) and USER_LDT.

Discussed in advance with Frank van der Linden.

kleink abaced98c3 Fix context handling for 32-bit environments:
* Really pass PSR ICC bits instead of raw CCR.
* Don't touch ASI and FPRS, which are not part of the 32-bit mcontext.
Also, correct printf conversions in svr4_printmcontext.

kleink db52b31344 Save/restore only the FP register file as far as the 32-bit environment
is concerned; in particular, don't overrun the [mu]context.

cyber 662f93aeeb Change the way boot strings are handled and the way the root device
is determined.  This allows multiple internal disks in a raq2 to work.

christos 002c8b43f1 Add a list with a brief description of each ports. With 43 ports right
now it is a bit tough to collect all the information.

XXX: Portmasters, or people who know better, please correct any mistakes.

tsutsui c5bc6249f0 Make sure to write out the dump header into an independent block
on the dump device on sun3x. (sync with sun3)
Now savecore(8) can find core dump in dumpdev properly.

XXX "target kcore /dev/mem" on gdb does not work yet.
