659aed5fed target/arm: Drop tcg_temp_free from translator-a64.c
Translators are no longer required to free tcg temporaries.

2503e60d12 target/arm: Drop new_tmp_a64_zero
Only the use within cpu_reg requires a writable temp,
so inline new_tmp_a64_zero there.  All other uses are
fine with a constant temp, so use tcg_constant_i64(0).

828fce78a8 target/arm: Drop DisasContext.tmp_a64
Translators are no longer required to free tcg temporaries,
therefore there's no need to record temps for later freeing.

This field was only used to avoid freeing globals.
Since we no longer free any temps, this is dead.

The dcblc instruction is used by u-boot in mpc85xx/start.S. Without it,
an illegal istruction exception is generated very early in the boot

0f3fea2171 target/ppc: Restrict 'qapi-commands-machine.h' to system emulation
Since commit a0e61807a3 ("qapi: Remove QMP events and commands from
user-mode builds") we don't generate the "qapi-commands-machine.h"
header in a user-emulation-only build.

Move the QMP functions from cpu_init.c (which is always compiled)
to monitor.c (which is only compiled when system-emulation
is selected).  Rename monitor.c to arm-qmp-cmds.c.

Note ppc_cpu_class_by_name() is used by both file units, so we
expose its prototype in "cpu-qom.h".

Daniel Henrique Barboza <dbarboza@ventanamicro.com> says:

This is a re-send of patch 1, which is already reviewed, with a
follow-up that uses riscv_cpu_cfg() in the remaining of the file. This
was suggested by Weiwei Li in the "[PATCH 0/4] RISCVCPUConfig related

Commit 752614cab8 ("target/riscv: rvv: Add tail agnostic for vector
load / store instructions") added code to set the tail elements to 1 in
the end of vext_ldst_stride(), vext_ldst_us(), vext_ldst_index() and
vext_ldff(). Aside from a env->vl versus an evl value being used in the
first loop, the code is being repeated 4 times.

Create a helper to avoid code repetition in all those functions.
Arguments that are used in the callers (nf, esz and max_elems) are
passed as arguments. All other values are being derived inside the
helper.

retrieving a CPUState pointer via env_cpu(). The CPU pointer is used
only to access the RISCVCPUConfig object and nothing else.

Let's use riscv_cpu_cfg() to access what we need directly without these
2 pointers.

target/riscv: Allow debugger to access {h, s}stateen CSRs
At present {h,s}stateen CSRs are not reported in the CSR XML
hence gdb cannot access them.

Fix it by adjusting their predicate() routine logic so that the
static config check comes before the run-time check, as well as
adding a debugger check.

target/riscv: gdbstub: Drop the vector CSRs in riscv-vector.xml
It's worth noting that the vector CSR predicate() has a similar
run-time check logic to the FPU CSR. With the previous patch our
gdbstub can correctly report these vector CSRs via the CSR xml.

Commit 719d3561b2 ("target/riscv: gdb: support vector registers for rv64 & rv32")
inserted these vector CSRs in an ad-hoc, non-standard way in the
riscv-vector.xml. Now we can treat these CSRs no different from
other CSRs.

target/riscv: gdbstub: Turn on debugger mode before calling CSR predicate()
Since commit 94452ac4cf ("target/riscv: remove fflags, frm, and fcsr from riscv-*-fpu.xml")
the 3 FPU CSRs are removed from the XML target decription. The
original intent of that commit was based on the assumption that
the 3 FPU CSRs will show up in the riscv-csr.xml so the ones in
riscv-*-fpu.xml are redundant. But unforuantely that is not true.
As the FPU CSR predicate() has a run-time check on MSTATUS.FS,
at the time when CSR XML is generated MSTATUS.FS is unset, hence
no FPU CSRs will be reported.

The FPU CSR predicate() already considered such a case of being
accessed by a debugger. All we need to do is to turn on debugger
mode before calling predicate().

target/riscv: Avoid reporting odd-numbered pmpcfgX in the CSR XML for RV64
At present the odd-numbered PMP configuration registers for RV64 are
reported in the CSR XML by QEMU gdbstub. However these registers do
not exist on RV64 so trying to access them from gdb results in 'E14'.

Move the pmpcfgX index check from the actual read/write routine to
the PMP CSR predicate() routine, so that non-existent pmpcfgX won't
be reported in the CSR XML for RV64.

At present riscv_csrrw_check() checks the CSR predicate() against
NULL and throws RISCV_EXCP_ILLEGAL_INST if it is NULL. But this is
a pure software check, and has nothing to do with the emulation of
the hardware behavior, thus it is inappropriate to return illegal
instruction exception when software forgets to install the hook.

the access control check, but the code changes did not agree with

In fact this was intentional. Add some comments there so that people

target/riscv: gdbstub: Check priv spec version before reporting CSR
The gdbstub CSR XML is dynamically generated according to the result
of the CSR predicate() result. This has been working fine until
commit 7100fe6c24 ("target/riscv: Enable privileged spec version 1.12")
introduced the privilege spec version check in riscv_csrrw_check().

When debugging the 'sifive_u' machine whose priv spec is at 1.10,
gdbstub reports priv spec 1.12 CSRs like menvcfg in the XML, hence
we see "remote failure reply 'E14'" message when examining all CSRs
via "info register system" from gdb.

Add the priv spec version check in the CSR XML generation logic to
fix this issue.

RISCV_FEATURE_MMU is set whether cpu->cfg.mmu is set, so let's just use

With this change the enum is also removed. It is worth noticing that
this enum, and all the RISCV_FEATURES_* that were contained in it,
predates the existence of the cpu->cfg object. Today, using cpu->cfg is
an easier way to retrieve all the features and extensions enabled in the

target/riscv: remove RISCV_FEATURE_PMP
RISCV_FEATURE_PMP is being set via riscv_set_feature() by mirroring the
cpu->cfg.pmp flag. Use the flag instead.

target/riscv/cpu.c: error out if EPMP is enabled without PMP
Instead of silently ignoring the EPMP setting if there is no PMP
available, error out informing the user that EPMP depends on PMP
support:

$ ./qemu-system-riscv64 -cpu rv64,pmp=false,x-epmp=true
qemu-system-riscv64: Invalid configuration: EPMP requires PMP support

This will force users to pick saner options in the QEMU command line.

target/riscv: allow MISA writes as experimental
At this moment, and apparently since ever, we have no way of enabling
RISCV_FEATURE_MISA. This means that all the code from write_misa(), all
the nuts and bolts that handles how to properly write this CSR, has
always been a no-op as well because write_misa() will always exit
earlier.

This seems to be benign in the majority of cases. Booting an Ubuntu
'virt' guest and logging all the calls to 'write_misa' shows that no
writes to MISA CSR was attempted. Writing MISA, i.e. enabling/disabling
RISC-V extensions after the machine is powered on, seems to be a niche
use.

After discussions in the mailing list, most notably in [1], we reached
the consensus that this code is not suited to be exposed to users
because it's not well tested, but at the same time removing it is a bit
extreme because we would like to fix it, and it's easier to do so with
the code available to use instead of fetching it from git log.

The approach taken here is to get rid of RISCV_FEATURE_MISA altogether
and use a new experimental flag called x-misa-w. The default value is
false, meaning that we're keeping the existing behavior of doing nothing
if a write_misa() is attempted. As with any existing experimental flag,
x-misa-w is also a temporary flag that we need to remove once we fix
write_misa().

target/riscv: do not mask unsupported QEMU extensions in write_misa()
The masking done using env->misa_ext_mask already filters any extension
that QEMU doesn't support. If the hart supports the extension then QEMU
supports it as well.

If the masking done by env->misa_ext_mask is somehow letting unsupported
QEMU extensions pass by, misa_ext_mask itself needs to be fixed instead.
