2014-12-20exec: change default exception_index value for migration to -1Paolo Bonzini1-2/+2
In QEMU 2.2 the exception_index value was added to the migration stream through a subsection. The default was set to 0, which is wrong and should have been -1. However, 2.2 does not have commit e511b4d (cpu-exec: reset exception_index correctly, 2014-11-26), hence in 2.2 the exception_index is never used and is set to -1 on the next call to cpu_exec. So we can change the migration stream to make the default -1. The effects are: - 2.2.1 -> 2.2.0: cpu->exception_index set incorrectly to 0 if it were -1 on the source; then reset to -1 in cpu_exec. This is TCG only; KVM does not use exception_index. - 2.2.0 -> 2.2.1: cpu->exception_index set incorrectly to -1 if it were 0 on the source; but it would be reset to -1 in cpu_exec anyway. This is TCG only; KVM does not use exception_index. - 2.2.1 -> 2.1: two bugs fixed: 1) can migrate backwards if cpu->exception_index is set to -1; 2) should not migrate backwards (but 2.2.0 allows it) if cpu->exception_index is set to 0 - 2.2.0 -> 2.3.0: 2.2.0 will send the subsection unnecessarily if exception_index is -1, but that is not a problem. 2.3.0 will set cpu->exception_index to -1 if it is 0 on the source, but this would be anyway a problem for 2.2.0 -> 2.2.x migration (due to lack of commit e511b4d in 2.2.x) so we can ignore it - 2.2.1 -> 2.3.0: everything works. In addition, play it safe and never send the subsection unless TCG is in use. KVM does not use exception_index (PPC KVM stores values in it for use in the subsequent call to ppc_cpu_do_interrupt, but does not need it as soon as kvm_handle_debug returns). Xen and qtest do not run any code for the CPU at all.

2014-12-19net: Use g_new() & friends where that makes obvious senseMarkus Armbruster3-5/+5
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T).

2014-12-19net: don't use set/get_pointer() in set/get_netdev()Jason Wang1-38/+44
Commit 1ceef9f27359cbe92ef124bf74de6f792e71f6fb (net: multiqueue support) tries to use set_pointer() and get_pointer() to set and get NICPeers which is not a pointer defined in DEFINE_PROP_NETDEV. This trick works but result a unclean and fragile implementation (e.g print_netdev and parse_netdev). This patch solves this issue by not using set/get_pinter() and set and get netdev directly in set_netdev() and get_netdev(). After this the parse_netdev() and print_netdev() were no longer used and dropped from the source.

The flag is a compatibility thing for older spice-server versions.

Add fast path to qemu_spice_display_switch in case old and new displaysurface have identical size (happens with display panning and page flipping). We just swap the backing store then and don't go through the whole process of deleting and creating the primary surface. To simplify the code a bit move mirror surface allocation to qemu_spice_display_switch(). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2014-12-16spice: reduce refresh rate in native modeGerd Hoffmann1-0/+3
Now that cursor updates are out of the way qxl needs the refresh timer only when when running in vga mode, for dirty bitmap checking. In native qxl mode the guest will notify us, so we don't need to poll and can use the idle interval (one refresh wakeup every few seconds).

2014-12-16spice: use bottom half instead of refresh timer for cursor updatesGerd Hoffmann4-7/+15
Calling directly doesn't work due to the qxl-render code running in spice server thread context. Meanwhile bottom half scheduling is thread-safe though, so we can use that to kick a cursor update in main i/o thread context.

Make sure the address space is unconditionally wrapped on 32-bit processors, that is ones that do not implement at least the MIPS III ISA. Also make MIPS16 SAVE and RESTORE instructions use address calculation rather than plain arithmetic operations for stack pointer manipulation so that their semantics for stack accesses follows the architecture specification.

2014-12-16target-mips: Fix CP0.Config3.ISAOnExc write accessesMaciej W. Rozycki3-2/+15
Fix CP0.Config3.ISAOnExc write accesses on microMIPS processors. This bit is mandatory for any processor that implements the microMIPS instruction set. This bit is r/w for processors that implement both the standard MIPS and the microMIPS instruction set. This bit is r/o and hardwired to 1 if only the microMIPS instruction set is implemented. There is no other bit ever writable in CP0.Config3 so defining a corresponding `CP0_Config3_rw_bitmask' member in `CPUMIPSState' is I think an overkill. Therefore make the ability to write the bit rely on the presence of ASE_MICROMIPS set in the instruction flags. The read-only case of the microMIPS instruction set being implemented only can be added when we add support for such a configuration. We do not currently have such support, we have no instruction flag that would control the presence of the standard MIPS instruction set nor any associated code in instruction decoding. This change is needed to boot a microMIPS Linux kernel successfully, otherwise it hangs early on as interrupts are enabled and then the exception handler invoked loops as its first instruction is interpreted in the wrong execution mode and triggers another exception right away. And then over and over again. We already check the current setting of the CP0.Config3.ISAOnExc in `set_hflags_for_handler' to set the ISA bit correctly on the exception handler entry so it is the ability to set it that is missing only.

2014-12-16target-mips: Fix the 64-bit case for microMIPS MOVE16 and MOVEPMaciej W. Rozycki1-3/+3
Fix microMIPS MOVE16 and MOVEP instructions on 64-bit processors by using register addition operations. This copies the approach taken with MIPS16 MOVE instructions (I8_MOV32R and I8_MOVR32 opcodes) and follows the observation that OPC_ADDU expands to tcg_gen_mov_tl whenever `rt' is 0 and `rs' is not, therefore copying `rs' to `rd' verbatim. This is not the case with OPC_ADDIU where a sign-extension from bit #31 is made, unless in the uninteresting case of `rs' being 0, losing the upper 32 bits of the value copied for any proper 64-bit values. This also serves as an optimization as one op is produced in generated code rather than two (again, unless `rs' is 0, where it doesn't change anything). Signed-off-by: Maciej W.
