tests/acceptance: bound the size of readline in s390_ccw_virtio
The read binary data as text via a PPM export of the frame buffer
seems a bit sketchy and it did blow up in the real world when the
assertion failed:

sun4m: don't connect two qemu_irqs directly to the same input
The sun4m board code connects both of the IRQ outputs of each ESCC to the
same slavio input qemu_irq. Connecting two qemu_irqs outputs directly to the
same input is not valid as it produces subtly wrong behaviour (for instance
if both the IRQ lines are high, and then one goes low, the PIC input will see
this as a high-to-low transition even though the second IRQ line should still
be holding it high).
This kind of wiring needs an explicitly created OR gate; add one.

hw/sparc: Make grlib-irqmp device handle its own inbound IRQ lines
Currently the GRLIB_IRQMP device is used in one place (the leon3 board),
but instead of the device providing inbound gpio lines for the board
to wire up, the board code itself calls qemu_allocate_irqs() with
the handler function being a set_irq function defined in the code
for the device.
Refactor this into the standard setup of a device having input
gpio lines.
This fixes a trivial Coverity memory leak report (the leon3
board code leaks the IRQ array returned from qemu_allocate_irqs()).

Chip-level Address Map

The address map indicated the allowed accesses at each address.
[...] W indicates a word access, and D indicates a double-word

The SLAVIO timer controller is implemented expecting 32-bit accesses.

a3d12d073e1 restricted the memory accesses to 32-bit, while
the device allows 64-bit accesses.
This was not an issue until commit
5d971f9e67 which reverted
("memory: accept mismatching sizes in memory_region_access_valid").
Fix by renaming .valid MemoryRegionOps as .impl, and add the valid
access range (W -> 4, D -> 8).

It turns out that OPENPIC_KVM, XICS_KVM and XIVE_KVM are marked
to depend on KVM but this has no effect when minikconf runs in
allnoconfig mode. Such reverse dependencies should rather be
handled with a 'select' statement, eg.
config OPENPIC
select OPENPIC_KVM if KVM
or even better by getting rid of the intermediate _KVM config
and directly checking CONFIG_KVM in the meson.build file:
specific_ss.add(when: ['CONFIG_KVM', 'CONFIG_OPENPIC'],
if_true: files('openpic_kvm.c'))
Go for the latter with OPENPIC, XICS and XIVE.
This went unnoticed so far because CI doesn't test the build with
--without-default-devices and KVM enabled on a POWER host.

spapr: Use spapr_drc_reset_all() at machine reset
Documentation of object_child_foreach_recursive() clearly stipulates
that "it is forbidden to add or remove children from @obj from the @fn

to spapr_drc_reset() can finalize the hot-unplug sequence of a PHB or a
PCI bridge, both of which will then in turn destroy their PCI DRCs. This
could potentially invalidate the iterator used by do_object_child_foreach().
It is pure luck that this haven't caused any issues so far.
Use spapr_drc_reset_all() since it can cope with DRC removal.

spapr: Fix reset of transient DR connectors
Documentation of object_property_iter_init() clearly stipulates that
"it is forbidden to modify the property list while iterating". But this
is exactly what we do when resetting transient DR connectors during CAS.

Change spapr_drc_reset() to return true if it caused a device to be
removed. Restart from scratch in this case. This can potentially
increase the overall DRC reset time, especially with a high maxmem
which generates a lot of LMB DRCs. But this kind of setup is rare,
and so is the use case of rebooting a guest while doing hot-unplug.

spapr: Fix buffer overflow in spapr_numa_associativity_init()
Running a guest with 128 NUMA nodes crashes QEMU:
../../util/error.c:59: error_setv: Assertion `*errp == NULL' failed.
The crash happens when setting the FWNMI migration blocker:
2861 if (spapr_get_cap(spapr, SPAPR_CAP_FWNMI) == SPAPR_CAP_ON) {
2862 /* Create the error string for live migration blocker */
2863 error_setg(&spapr->fwnmi_migration_blocker,
2864 "A machine check is being handled during migration. The handler"
2865 "may run and log hardware error on the destination");
2866 }
Inspection reveals that papr->fwnmi_migration_blocker isn't NULL:
(gdb) p spapr->fwnmi_migration_blocker
$1 = (Error *) 0x8000000004000000
Since this is the only place where papr->fwnmi_migration_blocker is
set, this means someone wrote there in our back. Further analysis
points to spapr_numa_associativity_init(), especially the part
that initializes the associative arrays for NVLink GPUs:
max_nodes_with_gpus = nb_numa_nodes + NVGPU_MAX_NUM;
ie. max_nodes_with_gpus = 128 + 6, but the array isn't sized to
accommodate the 6 extra nodes:
struct SpaprMachineState {
.
.
.
uint32_t numa_assoc_array[MAX_NODES][NUMA_ASSOC_SIZE];
Error *fwnmi_migration_blocker;
};
and the following loops happily overwrite spapr->fwnmi_migration_blocker,
and probably more:
for (i = nb_numa_nodes; i < max_nodes_with_gpus; i++) {
spapr->numa_assoc_array[i][0] = cpu_to_be32(MAX_DISTANCE_REF_POINTS);
for (j = 1; j < MAX_DISTANCE_REF_POINTS; j++) {
uint32_t gpu_assoc = smc->pre_5_1_assoc_refpoints ?
SPAPR_GPU_NUMA_ID : cpu_to_be32(i);
spapr->numa_assoc_array[i][j] = gpu_assoc;
}
spapr->numa_assoc_array[i][MAX_DISTANCE_REF_POINTS] = cpu_to_be32(i);
}
Fix the size of the array. This requires "hw/ppc/spapr.h" to see
NVGPU_MAX_NUM. Including "hw/pci-host/spapr.h" introduces a
circular dependency that breaks the build, so this moves the
definition of NVGPU_MAX_NUM to "hw/ppc/spapr.h" instead.

spapr: Allow memory unplug to always succeed
It is currently impossible to hot-unplug a memory device between
machine reset and CAS.
(qemu) device_del dimm1
Error: Memory hot unplug not supported for this guest
This limitation was introduced in order to provide an explicit
error path for older guests that didn't support hot-plug event
sources (and thus memory hot-unplug).
The linux kernel has been supporting these since 4.11. All recent
enough guests are thus capable of handling the removal of a memory
device at all time, including during early boot.
Lift the limitation for the latest machine type. This means that
trying to unplug memory from a guest that doesn't support it will
likely just do nothing and the memory will only get removed at
next reboot. Such older guests can still get the existing behavior
by using an older machine type.

spapr: Fix DR properties of the root node
Section 13.5.2 of LoPAPR mandates various DR related indentifiers
for all hot-pluggable entities to be exposed in the "ibm,drc-indexes",
"ibm,drc-power-domains", "ibm,drc-names" and "ibm,drc-types" properties
of their parent node. These properties are created with spapr_dt_drc().
PHBs and LMBs are both children of the machine. Their DR identifiers
are thus supposed to be exposed in the afore mentioned properties of
the root node.
When PHB hot-plug support was added, an extra call to spapr_dt_drc()
was introduced: this overwrites the existing properties, previously
populated with the LMB identifiers, and they end up containing only
PHB identifiers. This went unseen so far because linux doesn't care,
but this is still not conformant with LoPAPR.
Fortunately spapr_dt_drc() is able to handle multiple DR entity types
at the same time. Use that to handle DR indentifiers for PHBs and LMBs
with a single call to spapr_dt_drc(). While here also account for PMEM
DR identifiers, which were forgotten when NVDIMM hot-plug support was
added. Also add an assert to prevent further misuse of spapr_dt_drc().
With -m 1G,maxmem=2G,slots=8 passed on the QEMU command line we get:

The ppcuic_init() function is retained for the moment with its current
interface; in subsequent commits this will be tidied up to avoid the
allocation of an irq array.
This conversion adds VMState support.
It leaves the LOG_UIC() macro as-is to maximise the extent to which
this is simply code-movement rather than a rewrite (in new code it
would be better to use tracepoints).

hw/mips: Add Loongson-3 machine support
Add Loongson-3 based machine support, it use liointc as the interrupt
controler and use GPEX as the pci controller. Currently it can work with
both TCG and KVM.
As the machine model is not based on any exiting physical hardware, the
name of the machine is "loongson3-virt". It may be superseded in future
by a real machine model. If this happens, then a regular deprecation
procedure shall occur for "loongson3-virt" machine.
We now already have a full functional Linux kernel (based on Linux-5.4.x
LTS) here:
https://github.com/chenhuacai/linux
Of course the upstream kernel is also usable (the kvm host side and
guest side have both been upstream in Linux-5.9):
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
How to use QEMU/Loongson-3?
1, Download kernel source from the above URL;
2, Build a kernel with arch/mips/configs/loongson3_defconfig;
3, Boot a Loongson-3A4000 host with this kernel (for KVM mode);
4, Build QEMU-master with this patchset;
5, modprobe kvm (only necessary for KVM mode);
6, Use QEMU with TCG:
qemu-system-mips64el -M loongson3-virt,accel=tcg -cpu Loongson-3A1000 -kernel <path_to_kernel> -append ...
Use QEMU with KVM:
qemu-system-mips64el -M loongson3-virt,accel=kvm -cpu Loongson-3A4000 -kernel <path_to_kernel> -append ...
The "-cpu" parameter is optional here and QEMU will use the correct type for TCG/KVM automatically.

Currently the MIPS code uses the old clock_get_ns() API to

This relies on the clock having a period which is an exact number

clock: Introduce clock_ticks_to_ns()
The clock_get_ns() API claims to return the period of a clock in
nanoseconds. Unfortunately since it returns an integer and a
clock's period is represented in units of 2^-32 nanoseconds,
the result is often an approximation, and calculating a clock
expiry deadline by multiplying clock_get_ns() by a number-of-ticks
is unacceptably inaccurate.
Introduce a new API clock_ticks_to_ns() which returns the number
of nanoseconds it takes the clock to make a given number of ticks.
This function can do the complete calculation internally and
will thus give a more accurate result.

tcg/riscv: Fix illegal shift instructions
Out-of-range shifts have undefined results, but must not trap.
Mask off immediate shift counts to solve this problem.
This bug can be reproduced by running the following guest instructions:
xor %ecx,%ecx
sar %cl,%eax
cmovne %edi,%eax
After optimization, the tcg opcodes of the sar are
movi_i32 tmp3,$0xffffffffffffffff pref=all
sar_i32 tmp3,eax,tmp3 dead: 2 pref=all
mov_i32 cc_dst,eax sync: 0 dead: 1 pref=0xffc0300
mov_i32 cc_src,tmp3 sync: 0 dead: 0 1 pref=all
movi_i32 cc_op,$0x31 sync: 0 dead: 0 pref=all
The sar_i32 opcode is a shift by -1, which unmasked generates
0x200808d618:

tcg: Use memset for large vector byte replication
In
f47db80cc07, we handled odd-sized tail clearing for
the case of hosts that have vector operations, but did
not handle the case of hosts that do not have vector ops.
This was ok until
e2e7168a214b, which changed the encoding
of simd_desc such that the odd sizes are impossible.
Add memset as a tcg helper, and use that for all out-of-line
byte stores to vectors. This includes, but is not limited to,
the tail clearing operation in question.

tracetool: show trace-events filename/lineno in fmt string errors
The compiler encounters trace event format strings in generated code.
Format strings are error-prone and therefore clear compiler errors are
important.
Use the #line directive to show the trace-events filename and line
number in format string errors:
https://gcc.gnu.org/onlinedocs/gcc-10.2.0/cpp/Line-Control.html
For example, if the cpu_in trace event's %u is changed to %p the
following error is reported:
trace-events:29:18: error: format ‘%p’ expects argument of type ‘void *’, but argument 7 has type ‘unsigned int’ [-Werror=format=]
Line 29 in trace-events is where cpu_in is defined. This works for any
trace-events file in the QEMU source tree and the correct path is
displayed.
Unfortunately there does not seem to be a way to set the column, so "18"
is not the right character on that line.

tracetool: add output filename command-line argument
The tracetool.py script writes to stdout. This means the output filename
is not available to the script. Add the output filename to the
command-line so that the script has access to the filename.
This also simplifies the tracetool.py invocation. It's no longer
necessary to use meson's custom_build(capture : true) to save output.

pkg-config is enough for QEMU, since it does not need extra information
such as the path for certicate authorities. All supported platforms
today will all have pkg-config for curl, so we can drop curl-config.
