conversion interprets input bytes as multibyte sequences and displays
printable characters in the area corresponding to their first byte.
The remaining bytes are shown as "**".
actually work.
Make the PCI and PCCARD attachments provide a bus_get_resource_list()
method so that resource listing for PCCARD works. PCCARD does not
have a bus_get_resource_list() method (yet), so I faked up the
resource list management in if_ndis_pccard.c, and added
bus_get_resource_list() methods to both if_ndis_pccard.c and if_ndis_pci.c.
The one in the PCI attechment just hands off to the PCI bus code.
The difference is transparent to the NDIS resource handler code.
Fixed ndis_open_file() so that opening files which live on NFS
filesystems work: pass an actual ucred structure to VOP_GETATTR()
(NFS explodes if the ucred structure is NOCRED).
Make NdisMMapIoSpace() handle mapping of PCMCIA attribute memory
resources correctly.
Turn subr_ndis.c:my_strcasecmp() into ndis_strcasecmp() and export
it so that if_ndis_pccard.c can use it, and junk the other copy
of my_strcasecmp() from if_ndis_pccard.c.
Most of the changes are a direct result of adding thread awareness.
Typically, DDB_REGS is gone. All registers are taken from the
trapframe and backtraces use the PCB based contexts. DDB_REGS was
defined to be a trapframe on all platforms anyway.
Thread awareness introduces the following new commands:
thread X switch to thread X (where X is the TID),
show threads list all threads.
The backtrace code has been made more flexible so that one can
create backtraces for any thread by giving the thread ID as an
argument to trace.
With this change, ia64 has support for breakpoints.
o Make debugging code conditional upon KDB instead of DDB.
o Call kdb_enter() instead of Debugger().
o Remove implementation of Debugger().
o Check kdb_active instead of db_active.
o Call kdb_trap() according to the new world order.
o ksym_start and ksym_end changed type to vm_offset_t.
o Make debugging support conditional upon KDB instead of DDB.
o Call kdb_enter() instead of breakpoint().
o Remove implementation of Debugger().
o Call kdb_trap() according to the new world order.
unwinder:
o s/db_active/kdb_active/g
o Various s/ddb/kdb/g
o Add support for unwinding from the PCB as well as the trapframe.
Abuse a spare field in the special register set to flag whether
the PCB was actually constructed from a trapframe so that we can
make the necessary adjustments.
md_var.h:
o Add RSE convenience macros.
o Add ia64_bsp_adjust() to add or subtract from BSP while taking
NaT collections into account.
o Make debugging code conditional upon KDB instead of DDB.
o Declare ksym_start and ksym_end as extern and initialize them.
This was previously and bogusly handled by DDB itself.
o Call kdb_enter() instead of Debugger().
o Remove implementation of Debugger().
o Make debugging support conditional upon KDB instead of DDB.
o Remove implementation of Debugger().
o Don't make setjump() and longjump() conditional upon DDB.
o s/ddb_on_nmi/kdb_on_nmi/g
o Call kdb_reenter() when kdb_active is non-zero. Call kdb_trap()
otherwise.
o Make debugging support conditional upon KDB instead of DDB.
o Call kdb_trap() according to the new world order.
o Kill the NO_SIO option completely.
o Respect the boot_gdb environment variable.
o Don't make debug specific kernel options conditional.
o Remove implementation of Debugger().
it's in the way even more. Basicly: remove all alpha specific console
support from gfb(4), sio(4) and syscons(4). Rewrite the alpha console
initialization to be identical to all other platforms. In a nutshell:
call cninit().
The platform specific code now only sets or clears RB_SERIAL and thus
automaticly causes the right console to be selected.
sio.c:
o Replace the remote GDB hacks and use the GDB debug port interface
instead.
o Make debugging code conditional upon KDB instead of DDB.
o Call kdb_alt_break() instead of db_alt_break().
o Call kdb_enter() instead of breakpoint().
o Remove the ugly compatibility of using the console as the debug
port.
debugger is not active. The fixes breakages of DELAY() when
running in the debugger, because not calling getit() when the
debugger is active yields a DELAY that doesn't.
o s/ddb_on_nmi/kdb_on_nmi/g
o Rename sysctl machdep.ddb_on_nmi to machdep.kdb_on_nmi
o Make debugging support conditional upon KDB instead of DDB.
o Call kdb_reenter() when kdb_active is non-zero.
o Call kdb_trap() to enter the debugger when not already active.
o Update comments accordingly.
o Remove misplaced prototype of kdb_trap().
associated with a PR_ADDR protocol, make sure to update the m_nextpkt
pointer of the new head mbuf on the chain to point to the next record.
Otherwise, when we release the socket buffer mutex, the socket buffer
mbuf chain may be in an inconsistent state.
o Make debugging code conditional upon KDB instead of DDB.
o s/WITNESS_DDB/WITNESS_KDB/g
o s/witness_ddb/witness_kdb/g
o Rename the debug.witness_ddb sysctl to debug.witness_kdb.
o Call kdb_backtrace() instead of backtrace().
o Call kdb_enter() instead Debugger().
o Assert kdb_active instead of db_active.
o Make debugging code conditional upon KDB instead of DDB.
o Call kdb_enter() instead of Debugger().
o Call kdb_backtrace() instead of db_print_backtrace() or backtrace().
kern_mutex.c:
o Replace checks for db_active with checks for kdb_active and make
them unconditional.
kern_shutdown.c:
o s/DDB_UNATTENDED/KDB_UNATTENDED/g
o s/DDB_TRACE/KDB_TRACE/g
o Save the TID of the thread doing the kernel dump so the debugger
knows which thread to select as the current when debugging the
kernel core file.
o Clear kdb_active instead of db_active and do so unconditionally.
o Remove backtrace() implementation.
kern_synch.c:
o Call kdb_reenter() instead of db_error().
o Make debugging code conditional upon KDB instead of DDB.
o Call kdb_enter() instead of Debugger().
o Remove local (static) variable in_debugger. Use kdb_active instead.
o Call kdb_enter() instead of breakpoint().
o Call kdb_alt_break() instead of db_alt_break().
o Make debugging code conditional upon KDB instead of DDB.
o Make debugging code conditional upon KDB instead of DDB.
o Call kdb_alt_break() instead of db_alt_break().
o Call kdb_enter() instead of breakpoint().
o Call kdb_enter() instead of Debugger().
o Don't make such calls conditional upon KDB instead of DDB because
they're already conditional upon EN_DEBUG.
o Use kdb_alt_break() to handle the alternate break sequence instead
of handcoding it here.
o Remove GDB kluges to make this driver work with the pre-KDB remote
GDB code.
o Call kdb_enter() instead of Debugger().
Note that with this commit the dcons(4) driver cannot be used for
remote debugging anymore. This driver has to use the new GDB debug
port interface instead. Such has not been done yet.
