Commit 083afd18a9 ("target/arm: Restrict cpu_exec_interrupt()

but neglected to also limit it to TCG.

Thomas Huth 3d81e8cf0c hw/misc: Move some arm-related files from specific_ss into softmmu_ss
The header target/arm/kvm-consts.h checks CONFIG_KVM which is marked as
poisoned in common code, so the files that include this header have to
be added to specific_ss and recompiled for each, qemu-system-arm and
qemu-system-aarch64. However, since the kvm headers are only optionally
used in kvm-constants.h for some sanity checks, we can additionally
check the NEED_CPU_H macro first to avoid the poisoned CONFIG_KVM macro,
so kvm-constants.h can also be used from "common" files (without the
sanity checks - which should be OK since they are still done from other
target-specific files instead). This way, and by adjusting some other
include statements in the related files here and there, we can move some
files from specific_ss into softmmu_ss, so that they only need to be
compiled once during the build process.

The "MOVE TO PRIMARY/SECONDARY" instructions can also be called
from problem state. We just should properly check whether the
secondary-space access key is valid here, too, and inject a
privileged program exception if it is invalid.

The PSW key mask is a 16 bit field, and the psw_key variable is
in the range from 0 to 15, so it does not make sense to use
"0x80 >> psw_key" for testing the bits here. We should use 0x8000
instead.

Peter Maydell e2ce5fcde4 target/arm: Implement HCR_EL2.TID4 traps
For FEAT_EVT, the HCR_EL2.TID4 trap allows trapping of the cache ID
registers CCSIDR_EL1, CCSIDR2_EL1, CLIDR_EL1 and CSSELR_EL1 (and
their AArch32 equivalents).  This is a subset of the registers
trapped by HCR_EL2.TID2, which includes all of these and also the
CTR_EL0 register.

Our implementation already uses a separate access function for
CTR_EL0 (ctr_el0_access()), so all of the registers currently using
access_aa64_tid2() should also be checking TID4.  Make that function
check both TID2 and TID4, and rename it appropriately.

Peter Maydell 2d3ce4c6f3 target/arm: Implement HCR_EL2.TICAB,TOCU traps
For FEAT_EVT, the HCR_EL2.TICAB bit allows trapping of the ICIALLUIS
and IC IALLUIS cache maintenance instructions.

The HCR_EL2.TOCU bit traps all the other cache maintenance
instructions that operate to the point of unification:
 AArch64 IC IVAU, IC IALLU, DC CVAU
 AArch32 ICIMVAU, ICIALLU, DCCMVAU

The two trap bits between them cover all of the cache maintenance
instructions which must also check the HCR_TPU flag.  Turn the old
aa64_cacheop_pou_access() function into a helper function which takes
the set of HCR_EL2 flags to check as an argument, and call it from
new access_ticab() and access_tocu() functions as appropriate for
each cache op.

Peter Maydell d2fd931362 target/arm: Allow relevant HCR bits to be written for FEAT_EVT
FEAT_EVT adds five new bits to the HCR_EL2 register: TTLBIS, TTLBOS,
TICAB, TOCU and TID4.  These allow the guest to enable trapping of
various EL1 instructions to EL2.  In this commit, add the necessary
code to allow the guest to set these bits if the feature is present;
because the bit is always zero when the feature isn't present we
won't need to use explicit feature checks in the "trap on condition"
tests in the following commits.

Note that although full implementation of the feature (mandatory from
Armv8.5 onward) requires all five trap bits, the ID registers permit
a value indicating that only TICAB, TOCU and TID4 are implemented,
which might be the case for CPUs between Armv8.2 and Armv8.5.

The has_FOO for pointer-valued FOO are redundant, except for arrays.
They are also a nuisance to work with.  Recent commit "qapi: Start to

them step by step.  This is the step for qapi/machine*.json.

Said commit explains the transformation in more detail.  The invariant

Markus Armbruster d1c81c3496 qapi: Use returned bool to check for failure (again)
Commit 012d4c96e2 changed the visitor functions taking Error ** to
return bool instead of void, and the commits following it used the new
return value to simplify error checking.  Since then a few more uses
in need of the same treatment crept in.  Do that.  All pretty
mechanical except for

* balloon_stats_get_all()

  This is basically the same transformation commit 012d4c96e2 applied
  to the virtual walk example in include/qapi/visitor.h.

* set_max_queue_size()

  Additionally replace "goto end of function" by return.

Thomas Huth 21be74a9a5 target/s390x/tcg: Fix and improve the SACF instruction
The SET ADDRESS SPACE CONTROL FAST instruction is not privileged, it can be
used from problem space, too. Just the switching to the home address space
is privileged and should still generate a privilege exception. This bug is
e.g. causing programs like Java that use the "getcpu" vdso kernel function
to crash (see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=990417#26 ).

While we're at it, also check if DAT is not enabled. In that case the
instruction is supposed to generate a special operation exception.

Ard Biesheuvel 15f8f4671a target/arm: Use signed quantity to represent VMSAv8-64 translation level
The LPA2 extension implements 52-bit virtual addressing for 4k and 16k
translation granules, and for the former, this means an additional level
of translation is needed. This means we start counting at -1 instead of
0 when doing a walk, and so 'level' is now a signed quantity, and should
be typed as such. So turn it from uint32_t into int32_t.

This avoids a level of -1 getting misinterpreted as being >= 3, and
terminating a page table walk prematurely with a bogus output address.

Peter Maydell 26ba00cf58 target/arm: Don't do two-stage lookup if stage 2 is disabled
In get_phys_addr_with_struct(), we call get_phys_addr_twostage() if
the CPU supports EL2.  However, we don't check here that stage 2 is
actually enabled.  Instead we only check that inside
get_phys_addr_twostage() to skip stage 2 translation.  This means
that even if stage 2 is disabled we still tell the stage 1 lookup to
do its page table walks via stage 2.

This works by luck for normal CPU accesses, but it breaks for debug
accesses, which are used by the disassembler and also by semihosting
file reads and writes, because the debug case takes a different code
path inside S1_ptw_translate().

This means that setups that use semihosting for file loads are broken
(a regression since 7.1, introduced in recent ptw refactoring), and
that sometimes disassembly in debug logs reports "unable to read
memory" rather than showing the guest insns.

Fix the bug by hoisting the "is stage 2 enabled?" check up to
get_phys_addr_with_struct(), so that we handle S2 disabled the same
way we do the "no EL2" case, with a simple single stage lookup.

Ard Biesheuvel 312b71abce target/arm: Limit LPA2 effective output address when TCR.DS == 0
With LPA2, the effective output address size is at most 48 bits when
TCR.DS == 0. This case is currently unhandled in the page table walker,
where we happily assume LVA/64k granule when outputsize > 48 and
param.ds == 0, resulting in the wrong conversion to be used from a
page table descriptor to a physical address.

    if (outputsize > 48) {
        if (param.ds) {
            descaddr |= extract64(descriptor, 8, 2) << 50;
        } else {
            descaddr |= extract64(descriptor, 12, 4) << 48;
        }

So cap the outputsize to 48 when TCR.DS is cleared, as per the
architecture.

Paolo Bonzini 35d95e4126 target/i386: hardcode R_EAX as destination register for LAHF/SAHF
When translating code that is using LAHF and SAHF in combination with the
REX prefix, the instructions should not use any other register than AH;
however, QEMU selects SPL (SP being register 4, just like AH) if the
REX prefix is present.  To fix this, use deposit directly without
going through gen_op_mov_v_reg and gen_op_mov_reg_v.

Paolo Bonzini d1bb978ba1 target/i386: fix cmpxchg with 32-bit register destination
Unlike the memory case, where "the destination operand receives a write
cycle without regard to the result of the comparison", rm must not be
touched altogether if the write fails, including not zero-extending
it on 64-bit processors.  This is not how the movcond currently works,
because it is always followed by a gen_op_mov_reg_v to rm.

To fix it, introduce a new function that is similar to gen_op_mov_reg_v
but writes to a TCG temporary.

Considering that gen_extu(ot, oldv) is not needed in the memory case
either, the two cases for register and memory destinations are different
enough that one might as well fuse the two "if (mod == 3)" into one.
So do that too.

Some implementations (i.e. Loongson-2F) may decide to implement

As the eligibility of 64 bit FP instructions is already determined
by CP0St_FR, there is no need to check for COP1X again.

Jiaxun Yang 4bfc895383 target/mips: Disable DSP ASE for Octeon68XX
I don't have access to Octeon68XX hardware but according
to my investigation Octeon never had DSP ASE support.

As per "Cavium Networks OCTEON Plus CN50XX Hardware Reference
Manual" CP0C3_DSPP is reserved bit and read as 0. Also I do have
access to a Ubiquiti Edgerouter 4 which has Octeon CN7130 processor
and I can confirm CP0C3_DSPP is read as 0 on that processor.

Further more, in linux kernel:
arch/mips/include/asm/mach-cavium-octeon/cpu-feature-overrides.h
cpu_has_dsp is overridden as 0.

So I believe we shouldn't emulate DSP in QEMU as well.
