2017-06-15target/m68k: fix V flag for CC_OP_SUBxLaurent Vivier
V flag for subtraction is: v = (res ^ src1) & (src1 ^ src2) (see COMPUTE_CCR() in target/m68k/helper.c) But gen_flush_flags() uses: v = (res ^ src2) & (src1 ^ src2) The problem has been found with the following program: .global _start _start: move.l #-2147483648,%d0 subq.l #1,%d0 jvc 1f move.l #1,%d1 move.l #1,%d0 trap #0 1: move.l #0,%d1 move.l #1,%d0 trap #0 It works fine (exit(1)) on real hardware, and with "-singlestep". "-singlestep" uses gen_helper_flush_flags(), whereas without "-singlestep", V flag is computed directly in gen_flush_flags(). This patch updates gen_flush_flags() to have the same result as with gen_helper_flush_flags().

2017-06-13s390x/cpumodel: wire up cpu type + id for TCGDavid Hildenbrand
Let's properly expose the CPU type (machine-type number) via "STORE CPU ID" and "STORE SUBSYSTEM INFORMATION". As TCG emulates basic mode, the CPU identification number has the format "Annnnn", whereby A is the CPU address, and n are parts of the CPU serial number (0 for us for now). A specification exception will be injected if the address is not aligned to a double word. Low address protection will not be checked as we're missing some more general support for that.

2017-06-13target/s390x: rework PGM interrupt psw.addr handlingDavid Hildenbrand
We can tell from the program interrupt code, whether a program interrupt has to forward the address in the PGM new PSW (suppressing/terminated/completed) to point at the next instruction, or if it is nullifying and the PSW address does not have to be incremented. So let's not modify the PSW address outside of the injection path and handle this internally. We just have to handle instruction length auto detection if no valid instruction length can be provided. This should fix various program interrupt injection paths, where the PSW was not properly forwarded.

2017-06-07i386/kvm: do not zero out segment flags if segment is unusable or not presentRoman Pen
This is a fix for the problem [1], where VMCB.CPL was set to 0 and interrupt was taken on userspace stack. The root cause lies in the specific AMD CPU behaviour which manifests itself as unusable segment attributes on SYSRET[2]. Here in this patch flags are not touched even segment is unusable or is not present, therefore CPL (which is stored in DPL field) should not be lost and will be successfully restored on kvm/svm kernel side. Also current patch should not break desired behavior described in this commit: 4cae9c97967a ("target-i386: kvm: clear unusable segments' flags in migration") since present bit will be dropped if segment is unusable or is not present. This is the second part of the whole fix of the corresponding problem [1], first part is related to kvm/svm kernel side and does exactly the same: segment attributes are not zeroed out.

2017-06-06target/s390x: addressing exceptions are suppressingDavid Hildenbrand
We have to make the address in the old PSW point at the next instruction, as addressing exceptions are suppressing and not nullifying. I assume that there are a lot of other broken cases (as most instructions we care about are suppressing) - all trigger_pgm_exception() specifying and explicit number or ILEN_LATER look suspicious, however this is another story that might require bigger changes (and I have to understand when the address might already have been incremented first).

Use a common helper with PACK ASCII as the differences are limited to the stride of the source operand.

As MVCL and MVCLE only differ by their operands, use a common do_mvcl helper. Optimize it calling fast_memmove and fast_memset. Correctly write back addresses. Check that r1 and r2/r3 registers are even.

2017-06-06target/s390x: fix COMPARE LOGICAL LONG EXTENDEDAurelien Jarno
There are multiple issues with the COMPARE LOGICAL LONG EXTENDED instruction: - The test between the two operands is inverted, leading to an inversion of the cc values 1 and 2. - The address and length of an operand continue to be decreased after reaching the end of this operand. These values are then wrong write back to the registers. - We should limit the amount of bytes to process, so that interrupts can be served correctly. At the same time rename dest into src1 and src into src3 to match the operand names and make the code less confusing.

Improve fix_address to also handle the 24-bit mode. Rename fix_address to wrap_address to better explain what is changed. Replace the calls to get_address with x2 = 0 and b2 = 0 by call to wrap_address, leading to the removal of this function. Rename get_address_31fix into get_address.
