2015-10-07target-sparc: Remove gen_opc_jump_pcRichard Henderson1-9/+10
Since jump_pc[1] is always npc + 4, we can infer after incrementing that jump_pc[1] == pc + 4. Because of that, we can encode the branch destination into a single word, and store that in npc.

2015-10-07target-cris: Mirror gen_opc_pc into insn_startRichard Henderson1-1/+2
This perhaps isn't ideal in terms of (ab)using the "pc" field to encode both pc and ppc + delay branch state, as one has to be aware of this when examining opcode dumps. But it preserves existing logic, which will be good for bisection, and it certainly does save storage space.

2015-10-02Correctly re-init EFER state during INIT IPIBill Paul1-1/+1
When doing a re-initialization of a CPU core, the default state is to _not_ have 64-bit long mode enabled. This means the LME (long mode enable) and LMA (long mode active) bits in the EFER model-specific register should be cleared. However, the EFER state is part of the CPU environment which is preserved by do_cpu_init(), so if EFER.LME and EFER.LMA were set at the time an INIT IPI was received, they will remain set after the init completes. This is contrary to what the Intel architecture manual describes and what happens on real hardware, and it leaves the CPU in a weird state that the guest can't clear. To fix this, the 'efer' member of the CPUX86State structure has been moved to an area outside the region preserved by do_cpu_init(), so that it can be properly re-initialized by x86_cpu_reset().

2015-10-02target-i386: add ABM to Haswell* and Broadwell* CPU modelsPaolo Bonzini2-5/+25
ABM is only implemented as a single instruction set by AMD; all AMD processors support both instructions or neither. Intel considers POPCNT as part of SSE4.2, and LZCNT as part of BMI1, but Intel also uses AMD's ABM flag to indicate support for both POPCNT and LZCNT. It has to be added to Haswell and Broadwell because Haswell, by adding LZCNT, has completed the ABM. Tested with "qemu-kvm -cpu Haswell-noTSX,enforce" (and also with older machine types) on an Haswell-EP machine.

2015-10-02vl: Add another sanity check to smp_parse() functionThomas Huth1-1/+7
The code in smp_parse already checks the topology information for sockets * cores * threads < cpus and bails out with an error in that case. However, it is still possible to supply a bad configuration the other way round, e.g. with: qemu-system-xxx -smp 4,sockets=1,cores=4,threads=2 QEMU then still starts the guest, with topology configuration that is rather incomprehensible and likely not what the user wanted.

posix_fallocate emulation issue. https://bugzilla.redhat.com/show_bug.cgi?id=1265196 The following command fails on an NFS mountpoint: $ qemu-img create -f qcow2 -o preallocation=falloc disk.img 262144 Formatting 'disk.img', fmt=qcow2 size=262144 encryption=off cluster_size=65536 preallocation='falloc' lazy_refcounts=off qemu-img: disk.img: Could not preallocate data for the new file: Bad file descriptor The reason turns out to be because NFS doesn't support the posix_fallocate call. glibc emulates it instead. However glibc's emulation involves using the pread(2) syscall. The pread syscall fails with EBADF if the file descriptor is opened without the read open-flag (ie. open (..., O_WRONLY)). I contacted glibc upstream about this, and their response is here: https://bugzilla.redhat.com/show_bug.cgi?id=1265196#c9 There are two possible fixes: Use Linux fallocate directly, or (this fix) work around the problem in qemu by opening the file with O_RDWR instead of O_WRONLY.
