Currently, the upstream Spike ISA simulator allows more than
one CPUs so we update QEMU Spike machine on similar lines to
allow more than one CPUs.
The maximum number of CPUs for QEMU Spike machine is kept
same as QEMU Virt machine.

This patch adds an optional function pointer, "sym_cb", to
riscv_load_firmware() which provides the possibility to access
the symbol table during kernel loading.
The pointer is ignored, if supplied with flat (non-elf) firmware image.
The Spike board requires it locate the HTIF symbols from firmware ELF
passed via "-bios" option.

As-per RISC-V H-Extension v0.5 draft, the Stage2 SV32 page table has
12bits of VPN[1] and 10bits of VPN[0]. The additional 2bits in VPN[1]
is required to handle the 34bit intermediate physical address coming
from Stage1 SV32 page table. The 12bits of VPN[1] implies that Stage2
SV32 level-0 page table will be 16KB in size with total 4096 enteries
where each entry maps 4MB of memory (same as Stage1 SV32 page table).
The get_physical_address() function is broken for Stage2 SV32 level-0
page table because it incorrectly computes output physical address for
Stage2 SV32 level-0 page table entry.
The root cause of the issue is that get_physical_address() uses the
"widened" variable to compute level-0 physical address mapping which
changes level-0 mapping size (instead of 4MB). We should use the
"widened" variable only for computing index of Stage2 SV32 level-0
page table.

At present the board serial number is hard-coded to 1, and passed
to OTP model during initialization. Firmware (FSBL, U-Boot) uses
the serial number to generate a unique MAC address for the on-chip
ethernet controller. When multiple QEMU 'sifive_u' instances are
created and connected to the same subnet, they all have the same
MAC address hence it creates a unusable network.
A new "serial" property is introduced to specify the board serial
number. When not given, the default serial number 1 is used.

apply_to_qlist(), apply_to_node() work with QObjects. This is
designed for use by tests/qtest/qos-test.c, which gets the data in
that form via QMP. Goes back to commit fc281c8020 "tests: qgraph API
for the qtest driver framework".
Commit 275ab39d86 "fuzz: add support for qos-assisted fuzz targets"
added another user: qtest/fuzz/qos_fuzz.c. To get the data as
QObjects, it uses qmp_marshal_query_machines() and
qmp_marshal_qom_list_types().
All this code is rather cumbersome. Switch to working with generated
QAPI types instead:
* Replace apply_to_qlist() & friends by machines_apply_to_node() and
types_apply_to_node().
* Have qos_fuzz.c use qmp_query_machines() and qmp_qom_list_types()
instead.
* Have qos_test.c convert from QObject to the QAPI types.

spd_data_generate() splits @ram_size bytes into @nbanks RAM banks of
1 << sz_log2 MiB each, like this:
size = ram_size >> 20; /* work in terms of megabytes */
[...]
nbanks = 1;
while (sz_log2 > max_log2 && nbanks < 8) {
sz_log2--;
nbanks++;
}
Each iteration halves the size of a bank, and increments the number of
banks. Wrong: it should double the number of banks.
The bug goes back all the way to commit b296b664ab "smbus: Add a
helper to generate SPD EEPROM data".
It can't bite because spd_data_generate()'s current users pass only
@ram_size that result in *zero* iterations:
machine RAM size #banks type bank size
fulong2e 256 MiB 1 DDR 256 MiB
sam460ex 2048 MiB 1 DDR2 2048 MiB
1024 MiB 1 DDR2 1024 MiB
512 MiB 1 DDR2 512 MiB
256 MiB 1 DDR2 256 MiB
128 MiB 1 SDR 128 MiB
64 MiB 1 SDR 64 MiB
32 MiB 1 SDR 32 MiB
Apply the obvious, minimal fix. I admit I'm tempted to rip out the
unused (and obviously untested) feature instead, because YAGNI.
Note that this is not the final result, as spd_data_generate() next
increases #banks from 1 to 2 if possible. This is done "to avoid a
bug in MIPS Malta firmware". We don't even use this function with
machine type malta. *Shrug*

The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL. Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.
spd_data_generate() can pass @errp to error_setg() more than once when
it adjusts both memory size and type. Harmless, because no caller
passes anything that needs adjusting. Until the previous commit,
sam460ex passed types that needed adjusting, but not sizes.
spd_data_generate()'s contract is rather awkward:
If everything's fine, return non-null and don't set an error.
Else, if memory size or type need adjusting, return non-null and
set an error describing the adjustment.
Else, return null and set an error reporting why no data can be
generated.
Its callers treat the error as a warning even when null is returned.
They don't create the "smbus-eeprom" device then. Suspicious.
Since the previous commit, only "everything's fine" can actually
happen. Drop the unused code and simplify the callers. This gets rid
of the error API violation.

Requesting 32 or 64 MiB of RAM with the sam460ex machine type produces
a useless warning:
qemu-system-ppc: warning: Memory size is too small for SDRAM type, adjusting type
This is because sam460ex_init() asks spd_data_generate() for DDR2,
which is impossible, so spd_data_generate() corrects it to DDR.
The warning goes back to commit 08fd99179a "sam460ex: Clean up SPD
EEPROM creation".
Make sam460ex_init() pass the correct SDRAM type to get rid of the
warning.

qmp_guest_suspend_disk() and qmp_guest_suspend_ram() pass @local_err

qmp_guest_get_memory_blocks() passes &local_err to

The conversion of xen_pt_initfn() to xen_pt_realize() blindly replaced
XEN_PT_ERR() by error_setg(). Several error conditions that did not
fail xen_pt_initfn() now fail xen_pt_realize(). Unsurprisingly, the
cleanup on these errors looks highly suspicious.

The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL. Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.
virt_machine_device_plug_cb() passes @errp to
cryptodev_builtin_sym_close_session() in a loop. Harmless, because
cryptodev_builtin_sym_close_session() can't actually fail. Fix by
dropping its Error ** parameter.

timers_state.icount_time_shift must be in [0,63] to avoid undefined
behavior when shifting by it, e.g. in cpu_icount_to_ns().
icount_adjust() clamps it to [0,MAX_ICOUNT_SHIFT], with
MAX_ICOUNT_SHIFT = 10. configure_icount() doesn't. Fix that.

configure_icount() is wrong that way. Harmless, because its @errp is

Just as wrong (and just as harmless): when it fails, it can still
update global state.
Fix all that.

check_cache_dropped() calls error_setg() in a loop. It fails to break

qemu-img create, convert, amend, and measure use accumulate_options()
to merge multiple -o options. This is broken for -o "":
$ qemu-img create -f qcow2 -o backing_file=a -o "" -o backing_fmt=raw,size=1M new.qcow2
qemu-img: warning: Could not verify backing image. This may become an error in future versions.
Could not open 'a,backing_fmt=raw': No such file or directory
Formatting 'new.qcow2', fmt=qcow2 size=1048576 backing_file=a,,backing_fmt=raw cluster_size=65536 lazy_refcounts=off refcount_bits=16
$ qemu-img info new.qcow2
image: new.qcow2
file format: qcow2
virtual size: 1 MiB (1048576 bytes)
disk size: 196 KiB
cluster_size: 65536
--> backing file: a,backing_fmt=raw
Format specific information:
compat: 1.1
lazy refcounts: false
refcount bits: 16
corrupt: false
Merging these three -o the obvious way is wrong, because it results in
an unwanted ',' escape:
backing_file=a,,backing_fmt=raw,size=1M
~~
We could silently drop -o "", but Kevin asked me to reject it instead.

is_valid_option_list()'s purpose is ensuring qemu-img.c's can safely
join multiple parameter strings separated by ',' like this:
g_strdup_printf("%s,%s", params1, params2);
How it does that is anything but obvious. A close reading of the code
reveals that it fails exactly when its argument starts with ',' or
ends with an odd number of ','. Makes sense, actually, because when
the argument starts with ',', a separating ',' preceding it would get
escaped, and when it ends with an odd number of ',', a separating ','
following it would get escaped.
Move it to qemu-img.c and rewrite it the obvious way.

When opts_parse() sets @invalidp to true, qemu_opts_parse_noisily()
uses has_help_option() to decide whether to print help. This parses
the input string a second time.
Easy to avoid: replace @invalidp by @help_wanted.
