target/arm: Explicitly select short-format FSR for M-profile
For M-profile, there is no guest-facing A-profile format FSR, but we
still use the env->exception.fsr field to pass fault information from
the point where a fault is raised to the code in
arm_v7m_cpu_do_interrupt() which interprets it and sets the M-profile
specific fault status registers. So it doesn't matter whether we
fill in env->exception.fsr in the short format or the LPAE format, as
long as both sides agree. As it happens arm_v7m_cpu_do_interrupt()
assumes short-form.
In compute_fsr_fsc() we weren't explicitly choosing short-form for
M-profile, but instead relied on it falling out in the wash because
arm_s1_regime_using_lpae_format() would be false. This was broken in
commit
452c67a4 when we added v8R support, because we said "PMSAv8 is
always LPAE format" (as it is for v8R), forgetting that we were
implicitly using this code path on M-profile. At that point we would
hit a g_assert_not_reached():
ERROR:../../target/arm/internals.h:549:arm_fi_to_lfsc: code should not be reached

The specific assertion changed when commit
fcc7404eff24b4c added
"assert not M-profile" to arm_is_secure_below_el3(), because the
conditions being checked in compute_fsr_fsc() include
arm_el_is_aa64(), which will end up calling arm_is_secure_below_el3()
and asserting before we try to call arm_fi_to_lfsc():
#7 0x0000555555efaf43 in arm_is_secure_below_el3 (env=0x5555574665a0) at ../../target/arm/cpu.h:2396

Avoid the assertion and the incorrect FSR format selection by
explicitly making M-profile use the short-format in this function.

hw/arm/smmuv3: Make TLB lookup work for stage-2
Right now, either stage-1 or stage-2 are supported, this simplifies
how we can deal with TLBs.
This patch makes TLB lookup work if stage-2 is enabled instead of
stage-1.
TLB lookup is done before a PTW, if a valid entry is found we won't
do the PTW.
To be able to do TLB lookup, we need the correct tagging info, as
granularity and input size, so we get this based on the supported
translation stage. The TLB entries are added correctly from each
stage PTW.
When nested translation is supported, this would need to change, for
example if we go with a combined TLB implementation, we would need to
use the min of the granularities in TLB.
As stage-2 shouldn't be tagged by ASID, it will be set to -1 if S1P
is not enabled.

Parse stage-2 configuration from STE and populate it in SMMUS2Cfg.
Validity of field values are checked when possible.
Only AA64 tables are supported and Small Translation Tables (STT) are
not supported.
According to SMMUv3 UM(IHI0070E) "5.2 Stream Table Entry": All fields
with an S2 prefix (with the exception of S2VMID) are IGNORED when
stage-2 bypasses translation (Config[1] == 0).
Which means that VMID can be used(for TLB tagging) even if stage-2 is
bypassed, so we parse it unconditionally when S2P exists. Otherwise
it is set to -1.(only S1P)
As stall is not supported, if S2S is set the translation would abort.
For S2R, we reuse the same code used for stage-1 with flag
record_faults. However when nested translation is supported we would
need to separate stage-1 and stage-2 faults.

In preparation for adding stage-2 support, add Stage-2 PTW code.
Only Aarch64 format is supported as stage-1.
Nesting stage-1 and stage-2 is not supported right now.
HTTU is not supported, SW is expected to maintain the Access flag.
This is described in the SMMUv3 manual(IHI 0070.E.a)
"5.2. Stream Table Entry" in "[181] S2AFFD".
This flag determines the behavior on access of a stage-2 page whose
descriptor has AF == 0:
- 0b0: An Access flag fault occurs (stall not supported).
- 0b1: An Access flag fault never occurs.
An Access fault takes priority over a Permission fault.
There are 3 address size checks for stage-2 according to
(IHI 0070.E.a) in "3.4. Address sizes".
- As nesting is not supported, input address is passed directly to
stage-2, and is checked against IAS.
We use cfg->oas to hold the OAS when stage-1 is not used, this is set
in the next patch.
This check is done outside of smmu_ptw_64_s2 as it is not part of
stage-2(it throws stage-1 fault), and the stage-2 function shouldn't
change it's behavior when nesting is supported.
When nesting is supported and we figure out how to combine TLB for
stage-1 and stage-2 we can move this check into the stage-1 function
as described in ARM DDI0487I.a in pseudocode

- Input to stage-2 is checked against s2t0sz, and throws stage-2

spapr: Add SPAPR_CAP_AIL_MODE_3 for AIL mode 3 support for H_SET_MODE hcall
The behaviour of the Address Translation Mode on Interrupt resource is
not consistently supported by all CPU versions or all KVM versions: KVM
HV does not support mode 2, and does not support mode 3 on POWER7 or
early POWER9 processesors. KVM PR only supports mode 0. TCG supports all
modes (0, 2, 3) on CPUs with support for the corresonding LPCR[AIL] mode.
This leads to inconsistencies in guest behaviour and could cause problems
migrating guests.
This was not noticable for Linux guests for a long time because the
kernel only uses modes 0 and 3, and it used to consider AIL-3 to be
advisory in that it would always keep the AIL-0 vectors around, so it
did not matter whether or not interrupts were delivered according to
the AIL mode. Recent Linux guests depend on AIL mode 3 working as
specified in order to support the SCV facility interrupt. If AIL-3 can
not be provided, then H_SET_MODE must return an error to Linux so it can
disable the SCV facility (failure to do so can lead to userspace being
able to crash the guest kernel).
Add the ail-mode-3 capability to specify that AIL-3 is supported. AIL-0
is implied as the baseline, and AIL-2 is no longer supported by spapr.
AIL-2 is not known to be used by any software, but support in TCG could
be restored with an ail-mode-2 capability quite easily if a regression
is reported.
Modify the H_SET_MODE Address Translation Mode on Interrupt resource

ui/sdl2: disable SDL_HINT_GRAB_KEYBOARD on Windows
Windows sends an extra left control key up/down input event for
every right alt key up/down input event for keyboards with
international layout. Since commit
830473455f ("ui/sdl2: fix
handling of AltGr key on Windows") QEMU uses a Windows low level
keyboard hook procedure to reliably filter out the special left
control key and to grab the keyboard on Windows.
The SDL2 version 2.0.16 introduced its own Windows low level
keyboard hook procedure to grab the keyboard. Windows calls this
callback before the QEMU keyboard hook procedure. This disables
the special left control key filter when the keyboard is grabbed.
To fix the problem, disable the SDL2 Windows low level keyboard
hook procedure.

The following commits changed the code such that the fallback to MFSS for MFFSCRN,

bf8adfd88b547680aa857c46098f3a1e94373160 - target/ppc: Move mffscrn[i] to decodetree

The hardware will handle them as a MFFS instruction as the code did previously.
This means applications that were segfaulting under qemu when encountering these
instructions which is used in glibc libm functions for example.
The fallback for MFFSCDRN and MFFSCDRNI added in a later patch was also missing.
This patch restores the fallback to MFSS for these instructions on pre 3.0s ISAs
as the hardware decoder would, fixing the segfaulting libm code. It doesn't have
the fallback for 3.0 onwards to match hardware behaviour.

Hexagon: fix outdated `hex_new_*` comments
Some code comments refer to hex_new_value and hex_new_pred_value, which
have been transferred to DisasContext and, in the case of hex_new_value,
should now be accessed through get_result_gpr().
In order to fix this outdated comments and also avoid having to tweak

replace them with pseudocode.

Many Hexagon python scripts call hex_common.get_tagregs(), but only one
call site use the full reg structure given by this function. To make the
code cleaner, let's make get_tagregs() filter out the unused fields
(i.e. 'toss' and 'numregs'), properly removed the unused variables at
the call sites. The hex_common.bad_register() function is also adjusted
to work exclusively with 'regtype' and 'regid' args. For the single call
site that does use toss/numregs, we provide an optional parameter to
get_tagregs() which will restore the old full behavior.

Hexagon (target/hexagon) Fix assignment to tmp registers
The order in which instructions are generated by gen_insn() influences
assignment to tmp registers. During generation, tmp instructions (e.g.
generate_V6_vassign_tmp) use vreg_src_off() to determine what kind of
register to use as source. If some instruction (e.g.
generate_V6_vmpyowh_64_acc) uses a tmp register but is generated prior
to the corresponding tmp instruction, the vregs_updated_tmp bit map
isn't updated in time.
Exmple:
{ v14.tmp = v16; v25 = v14 } This works properly because
generate_V6_vassign_tmp is generated before generate_V6_vassign
and the bit map is updated.
{ v15:14.tmp = vcombine(v21, v16); v25:24 += vmpyo(v18.w,v14.h) }
This does not work properly because vmpyo is generated before
vcombine and therefore the bit map does not yet know that there's
a tmp register.
The parentheses in the decoding function were in the wrong place.
Moving them to the correct location makes shuffling of .tmp vector
registers work as expected.

We cannot use the generic reentrancy guard in the LSI code, so
we have to manually prevent endless reentrancy here. The problematic
lsi_execute_script() function has already a way to detect whether
too many instructions have been executed - we just have to slightly
change the logic here that it also takes into account if the function
has been called too often in a reentrant way.
