2019-02-11RISC-V: Add misa runtime write supportMichael Clark
This patch adds support for writing misa. misa is validated based on rules in the ISA specification. 'E' is mutually exclusive with all other extensions. 'D' depends on 'F' so 'D' bit is dropped if 'F' is not present. A conservative approach to consistency is taken by flushing the translation cache on misa writes. misa_mask is added to the CPU struct to store the original set of extensions.

PA-RISC specification says: "Setting the PSW Q-bit, PSW{28}, to 1 with this instruction, if it was not already 1, is an undefined operation." However, at least HP-UX 10.20 sets the Q bit from 0 to 1 with the SSM instruction. Tested this both on HP9000/712 and HP9000/785/C3750, both machines set the Q bit from 0 to 1 without exception.

2019-02-05target/arm: Make FPSCR/FPCR trapped-exception bits RAZ/WIPeter Maydell
The {IOE, DZE, OFE, UFE, IXE, IDE} bits in the FPSCR/FPCR are for enabling trapped IEEE floating point exceptions (where IEEE exception conditions cause a CPU exception rather than updating the FPSR status bits). QEMU doesn't implement this (and nor does the hardware we're modelling), but for implementations which don't implement trapped exception handling these control bits are supposed to be RAZ/WI. This allows guest code to test for whether the feature is present by trying to write to the bit and checking whether it sticks. QEMU is incorrectly making these bits read as written. Make them RAZ/WI as the architecture requires. In particular this was causing problems for the NetBSD automatic test suite.

2019-02-05i386: hvf: Fix smp boot hangsHeiher
The machine that with hvf accelerator and smp sometimes boot hangs because all processors are executing instructions at startup, including early I/O emulations. We should just allow the bootstrap processor to initialize the machine and then to wake up slave processors by interrupt.

2019-02-05gdbstub: Fix i386/x86_64 machine description and add control registersDoug Gale
The machine description we send is being (silently) thrown on the floor by GDB and GDB silently uses the default machine description, because the xml parse fails on <feature> nested within <feature>. Changes to the xml in qemu source code have no effect. In addition, the default machine description has fs_base, which fails to be retrieved, which breaks the whole register window. Add it and the other control registers. Signed-off-by: Doug Gale <doug16k@gmail.com> Message-Id: <20190124040457.2546-1-doug16k@gmail.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2019-02-05i386: hvf: Don't miss 16-bit displacementRoman Bolshakov
In 16-bit addressing mode, when Mod = 0 and R/M = 6, decoded displacement doesn't reach decode_linear_addr and gets lost. Instructions that involve the combination of ModRM always get a pointer with zero offset from the beginning of DS segment. The change fixes drawing in F-BIRD from day 1 of '18 advent calendar.

2019-02-04s390x/tcg: Don't model FP registers as globalsDavid Hildenbrand
As floating point registers overlay some vector registers and we want to make use of the general tcg_gvec infrastructure that assumes vectors are not stored in globals but in memory, don't model floating point registers as globals anymore. This is then similar to how arm handles it. Reading/writing a floating point register means reading/writing memory now. Break up ugly in2_x2() handling that modifies both, in1 and in2 into in2_x2l and in2_x2h. This makes things more readable. Also, in1_x1() is ugly as it touches out/out2, get rid of that and use prep_x1() instead. As we are no longer able to use the original global variables for out/out2, we have to use new temporary variables and write from them to the target registers using wout_ helpers. E.g. an instruction that reads and writes x1 will use - prep_x1 to get the values into out/out2 - wout_x1 to write the values from out/out2 This special handling is needed for x1 as it is often used along with other inputs, so in1/in2 is already used.

2019-02-04s390x: remove direct reference to mem_path global from s390x codeIgor Mammedov
I plan to deprecate -mem-path option and replace it with memory-backend, for that it's necessary to get rid of mem_path global variable. Do it for s390x case, replacing it with alternative way to enable 1Mb hugepages capability. Todo that replace qemu_mempath_getpagesize() with qemu_getrampagesize() which also checks for -mem-path provided RAM.

Following on from the previous work, there are numerous endian-related hacks in int_helper.c that can now be replaced with Vsr* macros. There are also a few places where the VECTOR_FOR_INORDER_I macro can be replaced with a normal iterator since the processing order is irrelevant.
