| * target-hppa: Implement linux-user gateway pageRichard Henderson2017-01-231-4/+81
| | | | | | | | | | | | | | | | | | | | | | | | For linux, page 0 is mapped as an execute-only gateway. A gateway page is a special bit in the page table that allows a B,GATE insn within that page to raise processor permissions. This is how system calls are implemented for HPPA. Rather than actually map anything here, or handle permissions at all, implement the semantics of the actual linux syscall entry points. Signed-off-by: Richard Henderson <rth@twiddle.net>

| * target-hppa: Add nullification frameworkRichard Henderson2017-01-231-4/+224
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The HPPA cpu has a unique form of predicated execution in which almost any instruction can set the PSW[N] (or "nullify") bit, which suppresses execution (and even decoding) of the following instruction. Execution of a nullified insn clears the PSW[N] bit. This adds a generic framework for branching over nullified insns, or for sufficiently simple insns, transforming the writeback of the result to a conditional move. In the process, we want to be able to represent PSW[N] as a TCG condition, which implies management of the related tcg temps. Signed-off-by: Richard Henderson <rth@twiddle.net>
| * target-hppa: Add framework and enable compilationRichard Henderson2017-01-2312-3/+1116
| | | | | | | | | | | | | | | | | | | | This is just about the minimum required to enable compilation without actually executing any instructions. This contains the HPPACPU structure and the required callbacks, the gdbstub, the basic translation loop, and a translate_one function that always results in an illegal instruction.

| * target-hppa: Add softfloat specializationsRichard Henderson2017-01-231-1/+19
| | | | | | | | | | | | | | | | | | | | | | Like the original MIPS, HPPA has the MSB of an SNaN set. However, it has different rules for silencing an SNaN: (1) msb is cleared and (2) msb-1 must be set if the fraction is now zero, and (implementation defined) may be set always. I haven't checked real hardware but chose the set always alternative because it's easy and within spec. Signed-off-by: Richard Henderson <rth@twiddle.net>

| * | io: introduce a DNS resolver APIDaniel P. Berrange2017-01-235-2/+509
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently DNS resolution is done automatically as part of the creation of a QIOChannelSocket object instance. This works ok for network clients where you just end up a single network socket, but for servers, the results of DNS resolution may require creation of multiple sockets. Introducing a DNS resolver API allows DNS resolution to be separated from the socket object creation. This will make it practical to create multiple QIOChannelSocket instances for servers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the QIOTaskFunc signature takes an Object * for the source, and an Error * for any error. We also need to be able to provide a result pointer. Rather than continue to add parameters to QIOTaskFunc, remove the existing ones and simply pass the QIOTask object instead. This has methods to access all the other data items required in the callback impl. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P. Berrange <berrange@redhat.com>

| * x86: ioapic: fix fail migration when irqchip=splitPeter Xu2017-01-161-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Split irqchip works based on the fact that we kept the first 24 gsi routing entries inside KVM for userspace ioapic's use. When system boot, we'll reserve these MSI routing entries before hand. However, after migration, we forgot to re-configure it up in the destination side. The result is, we'll get invalid gsi routing entries after migration (all empty), and we get interrupts with vector=0, then strange things happen, like keyboard hang. The solution is simple - we update them after migration, which is a one line fix.

| * x86: ioapic: add traces for ioapicPeter Xu2017-01-162-2/+22
| | | | | | | | | | | | | | | | | | | | From time to time, there are issues with ioapic, either on guest side or on hypervisor side. Good to have some persistent traces for better triaging and debugging.
