a sigjmp_buf.

This fixes a stack_chk fail in a OSX 32bit build. Since at least on
OSX sigjmp_buf is four bytes larger then a jmpbuf, resulting in an
overflow in sigsetjmp. Due to variable reordering this overwrites
the stack cookie.

linux-user: Fix up timer id handling

When creating a timer handle, we give the timer id a special magic offset
of 0xcafe0000. However, we never mask that offset out of the timer id before
we start using it to dereference our timer array. So we always end up aborting
timer operations because the timer id is out of bounds.

This was not an issue before my patch e52a99f756e ("linux-user: Simplify
timerid checks on g_posix_timers range") because before we would blindly mask
anything above the first 16 bits.

This patch simplifies the code around timer id creation by introducing a proper
target_timer_id typedef that is s32, just like Linux has it. It also changes the
magic offset to a value that makes all timer ids be positive.

5 years agomips: Ensure PC update with MTC0 single-stepping
Maciej W. Rozycki [Thu, 6 Nov 2014 20:38:10 +0000 (20:38 +0000)] 
mips: Ensure PC update with MTC0 single-stepping

Correct the way PC is updated when single-stepping instructions, by
keeping the old PC only for the BS_EXCP (exception condition) state.

Some MTC0 (and possibly other) instructions switch to the BS_STOP state
to terminate the current translation block, so that the state transition
of the simulated CPU resulting from the CP0 operation takes effect with
the following instruction.  This happens with `mtc0 <reg>,c0_config' for
example, typically used to set KSEG0 cacheability.

While single-stepping this has a side-effect of not advancing the PC
past the instruction just executed; subsequent single-step traps will
stop at the same instruction repeatedly.  Example:

(gdb) stepi
0x80004d24 in _start ()

Standard MIPS FP instruction encodings have a more regular structure and
branches are covered with a single umbrella along other instructions.
This is not the case with the microMIPS encoding, this case has to be
taken care of explicitly here.  Code to do so has been copied from the
standard MIPS code handler for OPC_CP1, in `decode_opc'.

Problems arising from this bug will generally only show up on user

switches, such as Linux.  It will also more readily trigger if software

spapr: Cleanup machine naming conventions, and prepare for 2.2 release

As of qemu-2.1, spapr/pseries, has a set of versioned machine classes to
represent the machine type as it appeared to the guest in different qemu
versions.  This allows for safe migration of guests between current and
future qemu versions.

However, these are organized a bit differently from those for PC: on PC,
the default plain "pc" machine type is just an alias for the most recent
versioned machine type.  In sPAPR, it names the base machine class from
which the versioned types are derived.

The PC approach is preferable; it makes it clearer which explicit version
is the current one.  Additionally updating the "current" machine as the
base class makes it even more likely than otherwise to incorrectly alter
the versioned machines' behaviour when updating the current machine.

Therefore this patch changes sPAPR to the PC approach - the base class
becomes abstract, and plain "pseries" becomes an alias for the most
recent versioned machine class.  Since qemu-2.1 is now released, we also
create a new pseries-2.2 machine type, to incorporate changes during this
development cycle (for now it is identical to pseries-2.1).

The virtex-ml507 is a Xilinx CPU based system, and requires several sub
devices which are only included with CONFIG_XILINX.  Therefore, it should
only be compiled if CONFIG_XILINX is set.

 * CPUID_EXT_XTPR

As using "enforce" mode is the only way to ensure guest ABI doesn't
change when moving to a different host, we should make "enforce" mode
the default or at least encourage management software to always use it.

In turn, to make "enforce" usable, we need CPU models that work without
always requiring some features to be explicitly disabled. This patch
removes the above features from all CPU model definitions.

We won't need any machine-type compat code for those changes, because it
is impossible to have existing VMs with those features enabled.
