3031a4311e Fix two (2) bugs in one (1) statement:
o  fix the len argument of memcmp(3) to be the size of the node field
   of the uuid structure, not the size of the uuid structure itself.
   We're comparing the node fields...
o  uuid_compare(3) is specified to return -1, 0 or 1, depending on
   the outcome of the comparison. memcmp(3) returns the difference
   between the first differing bytes. Hence, we cannot ever return
   the return value of memcmp(3) as-is.

778a4a9dd4 Grok async contexts. When a thread is interrupted and an upcall
happens, the context of the interrupted thread is exported to
userland. Unlike most contexts, it will be an async context and
we cannot easily use our existing functions to set such a
context.
To avoid a lot of complexity that may possibly interfere with
the common case, we simply let the kernel deal with it. However,
we don't use the EPC based syscall path to invoke setcontext(2).
No, we use the break-based syscall path. That way the trapframe
will be compatible with the context we're trying to restore and
we save the kernel a lot of trouble. The kind of trouble we did
not want to go though ourselves...

However, we also need to set the threads mailbox and there's no
syscall to help us out. To avoid creating a new syscall, we use
the context itself to pass the information to the kernel so that
the kernel can update the mailbox. This involves setting a flag
(_MC_FLAGS_KSE_SET_MBOX) and setting ifa (the address) and isr
(the value).

998e124837 Implement mbtowc() in terms of mbrtowc(), and wctomb() in terms of wcrtomb(). 2003-08-07 07:59:36 +00:00
Tim J. Robbins
dab4fca49b Implement btowc() in terms of mbrtowc() instead of sgetrune(), and
wctob() in terms of wcrtomb() instead of sputrune(). There should be
no functional differences, but there may be a small performance hit
because we make an extra function call.

The aim here is to have as few functions as possible calling
s{get,put}rune() to make it easier to remove them in the future.

d7c68311ee Avoid a level of indirection to get from the thread pointer to the
TCB. We know that the thread pointer points to &tcb->tcb_tp, so all
we have to do is subtract offsetof(struct tcb, tcb_tp) from the
thread pointer to get to the TCB. Any reasonably smart compiler will
translate accesses to fields in the TCB as negative offsets from TP.

In _tcb_set() make sure the fake TCB gets a pointer to the current
KCB, just like any other TCB. This fixes a NULL-pointer dereference
in _thr_ref_add() when it tried to get the current KSE.

119fb38770 Define the static TLS as an array of long double. This will guarantee
that the TLS is 16-byte aligned, as well as guarantee that the thread
pointer is 16-byte aligned as it points to struct ia64_tp. Likewise,
struct tcb and struct ksd are also guaranteed to be 16-byte aligned
(if they weren't already).

9a3ea63e79 Define THR_GETCONTEXT and THR_SETCONTEXT in terms of the userland
context functions. We don't need to enter the kernel anymore. The
contexts are compatible (ie a context created by getcontext() can
be restored by _ia64_restore_context()).

While here, make the use of THR_ALIGNBYTES and THR_ALIGN a no-op.

50be3a75cc o In _ia64_save_context() clear the return registers except for r8.
We write 1 for r8 in the context so that _ia64_restore_context()
   will return with a non-zero value. _ia64_save_context() always
   return 0.
o  In _ia64_restore_context(), don't restore the thread pointer. It
   is not normally part of the context. Also, restore the return
   registers. We get called for contexts created by getcontext(),
   which means we have to restore all the syscall return values.

8955f59879 Override the default stubs for getcontext(2) and swapcontext(2) so
that we can flush the register stack prior to entering the kernel.
This avoids having dirty registers and saves us from having to
manually write them to the backing store from within the kernel.
In that respect, flushing the RSE is both functionally required as
well as performance optimal.

On average we had 18 dirty registers when getcontext(2) was called
from libthr. Since libthr does not switch back to a context created
by getcontext(2), not having dealt with the dirty registers was
harmless.
