2019-01-07target/arm: SVE brk[ab] merging does not have s bitRichard Henderson
While brk[ab] zeroing has a flags setting option, the merging variant does not. Retain the same argument structure, to share expansion but force the flag zero and do not decode bit 22.

2019-01-03target/mips: MXU: Add handlers for logic instructionsAleksandar Markovic
Add translation handlers for four logic MXU instructions. It should be noted that there is an error in MXU documentation (dated June 2017) regarding opcodes for this group of instructions. This was confirmed by running tests on hardware, and also by looking up other related public source trees (binutils, Android NDK). In initial MXU patches to QEMU, opcodes for MXU logic instructions were created to be in accordance with the MXU documentation, therefore the error from was propagated. This patch corrects that, changing the involved code. Besides that, as MXU was designed and implemented only for 32-bit CPUs, corresponding preprosessor conditions were added around MXU code, which allows more flexible implementation of MXU handlers.

2018-12-21target/ppc: tcg: Implement addex instructionSuraj Jitindar Singh
Implement the addex instruction introduced in ISA V3.00 in qemu tcg. The add extended using alternate carry bit (addex) instruction performs the same operation as the add extended (adde) instruction, but using the overflow (ov) field in the fixed point exception register (xer) as the carry in and out instead of the carry (ca) field. The instruction has a Z23-form, not an XO form, as follows: ------------------------------------------------------------------ | 31 | RT | RA | RB | CY | 170 | 0 | ------------------------------------------------------------------ 0 6 11 16 21 23 31 32 However since the only valid form of the instruction defined so far is CY = 0, we can treat this like an XO form instruction. There is no dot form (addex.) of the instruction and the summary overflow (so) bit in the xer is not modified by this instruction. For simplicity we reuse the gen_op_arith_add function and add a function argument to specify where the carry in input should come from and the carry out output be stored (note must be the same location).

2018-12-20target/riscv/pmp.c: Fix pmp_decode_napot()Anup Patel
Currently, start and end address of a PMP region are not decoded correctly by pmp_decode_napot(). Let's say we have a 128KB PMP region with base address as 0x80000000. Now, the PMPADDRx CSR value for this region will be 0x20003fff. The current pmp_decode_napot() implementation will decode PMPADDRx CSR as t1=14, base=0x100000000, and range=0x1ffff whereas it should have decoded PMPADDRx CSR as t1=14, base=0x80000000, and range=0x1fff. This patch fixes the base value decoding in pmp_decode_napot() when PMPADDRx CSR is not -1 (i.e. 0xffffffffffffffff).

2018-12-14target/arm: Create timers in realize, not initPeter Maydell
The timer_new() function allocates memory; this means that if we call it in the CPU's init method we would need to provide an instance_finalize method to free it. Defer the timer creation to the realize function instead. This fixes a memory leak spotted by clang LeakSanitizer when a CPU object is created for introspection.

2018-12-14target/arm: Free name string in ARMCPRegInfo hashtable entriesPeter Maydell
When we add a new entry to the ARMCPRegInfo hash table in add_cpreg_to_hashtable(), we allocate memory for tehe ARMCPRegInfo struct itself, and we also g_strdup() the name string. So the hashtable's value destructor function must free the name string as well as the struct. Spotted by clang's leak sanitizer. The leak here is a small one-off leak at startup, because we don't support CPU hotplug, and so the only time when we destroy hash table entries is for the case where ARM_CP_OVERRIDE means we register a wildcard entry and then override it later.

2018-12-11i386: Add "stibp" flag nameEduardo Habkost
The STIBP flag may be supported by the host KVM module, so QEMU can allow it to be configured manually, and it can be exposed to guests when using "-cpu host". No additional migration code is required because the whole contents of spec_ctrl is already migrated in the "cpu/spec_ctrl" section. Corresponding KVM patch was submitted at: https://lore.kernel.org/lkml/20181205191956.31480-1-ehabkost@redhat.com/ Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Message-Id: <20181210180250.31299-1-ehabkost@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>
2018-12-11target/i386/kvm.c: Don't mark cpuid_data as QEMU_PACKEDPeter Maydell
clang complains about taking the address of a packed member of a struct: target/i386/kvm.c:1245:27: warning: taking address of packed member 'cpuid' of class or structure '' may result in an unaligned pointer value [-Waddress-of-packed-member] c = cpuid_find_entry(&cpuid_data.cpuid, 1, 0); ^~~~~~~~~~~~~~~~ target/i386/kvm.c:1297:31: warning: taking address of packed member 'cpuid' of class or structure '' may result in an unaligned pointer value [-Waddress-of-packed-member] c = cpuid_find_entry(&cpuid_data.cpuid, kvm_base, 0); ^~~~~~~~~~~~~~~~ The kernel's definitions of struct kvm_cpuid2 and struct kvm_cpuid_entry2 are carefully set up with padding fields so that there is no between-struct padding anyway, so the QEMU_PACKED annotation is unnecessary and might result in the compiler generating worse code. Drop it, and instead assert at build time that there is no stray padding.

2018-12-03i386: hvf: Fix overrun of _decode_tbl1Roman Bolshakov
Single opcode instructions in ff group were incorrectly processed because an overrun of _decode_tbl1[0xff] resulted in access of _decode_tbl2[0x0]. Thus, decode_sldtgroup was called instead of decode_ffgroup: 7d71: decode_sldtgroup: 1 Unimplemented handler (7d71) for 108 (ff 0) While at it correct maximum length for _decode_tbl2 and _decode_tbl3.
