6233a13859 mips/malta: pass RNG seed via env var and re-randomize on reboot
As of the kernel commit linked below, Linux ingests an RNG seed
passed as part of the environment block by the bootloader or firmware.
This mechanism works across all different environment block types,
generically, which pass some block via the second firmware argument. On
malta, this has been tested to work when passed as an argument from
U-Boot's linux_env_set.

As is the case on most other architectures (such as boston), when
booting with `-kernel`, QEMU, acting as the bootloader, should pass the
RNG seed, so that the machine has good entropy for Linux to consume. So
this commit implements that quite simply by using the guest random API,
which is what is used on nearly all other archs too. It also
reinitializes the seed on reboot, so that it is always fresh.

4fbae24450 mips/boston: re-randomize rng-seed on reboot
When the system reboots, the rng-seed that the FDT has should be
re-randomized, so that the new boot gets a new seed. Since the FDT is in
the ROM region at this point, we add a hook right after the ROM has been
added, so that we have a pointer to that copy of the FDT.

bd64c210ce hw/mips/malta: turn off x86 specific features of PIIX4_PM
QEMU crashes trying to save VMSTATE when only MIPS target are compiled in
  $ qemu-system-mips -monitor stdio
  (qemu) migrate "exec:gzip -c > STATEFILE.gz"
  Segmentation fault (core dumped)

It happens due to PIIX4_PM trying to parse hotplug vmstate structures
which are valid only for x86 and not for MIPS (as it requires ACPI
tables support which is not existent for ithe later)

Issue was probably exposed by trying to cleanup/compile out unused
ACPI bits from MIPS target (but forgetting about migration bits).

Disable compiled out features using compat properties as the least
risky way to deal with issue.

5e19cc68fb hw/mips: boston: pass random seed to fdt
If the FDT contains /chosen/rng-seed, then the Linux RNG will use it to
initialize early. Set this using the usual guest random number
generation function. This FDT node is part of the DT specification.

I'd do the same for other MIPS platforms but boston is the only one that
seems to use FDT.

0c285e0128 hw/block/fdc-sysbus: Always mark sysbus floppy controllers as not having DMA
The sysbus floppy controllers (devices sysbus-fdc and sun-fdtwo)
don't support DMA.  The core floppy controller code expects this to
be indicated by setting FDCtrl::dma_chann to -1.  This used to be
done in the device instance_init functions sysbus_fdc_initfn() and
sun4m_fdc_initfn(), but in commit 1430759ec3 we refactored this code
and accidentally lost the setting of dma_chann.

For sysbus-fdc this has no ill effects because we were redundantly
also setting dma_chann in fdctrl_init_sysbus(), but for sun-fdtwo
this means that guests which try to enable DMA on the floppy
controller will cause QEMU to crash because FDCtrl::dma is NULL.

Set dma_chann to -1 in the common instance init, and remove the
redundant code in fdctrl_init_sysbus() that is also setting it.

There is a six-year-old FIXME comment in the jazz board code to the
effect that in theory it should support doing DMA via a custom DMA
controller.  If anybody ever chooses to fix that they can do it by
adding support for setting both FDCtrl::dma_chann and FDCtrl::dma.
(A QOM link property 'dma-controller' on the sysbus device which can
be set to an instance of IsaDmaClass is probably the way to go.)

f9bcb2d684 Warn user if the vga flag is passed but no vga device is created
A global boolean variable "vga_interface_created"(declared in softmmu/globals.c)
has been used to track the creation of vga interface. If the vga flag is passed
in the command line "default_vga"(declared in softmmu/vl.c) variable is set to 0.
To warn user, the condition checks if vga_interface_created is false
and default_vga is equal to 0. If "-vga none" is passed, this patch will not warn the
user regarding the creation of VGA device.

The warning "A -vga option was passed but this
machine type does not use that option; no VGA device has been created"
is logged if vga flag is passed but no vga device is created.

This patch has been tested for x86_64, i386, sparc, sparc64 and arm boards.

b21e238037 Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n).  It's also safer,
for two reasons.  One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

sizeof(T).

a13bfa5a05 hw/mips/jazz: Map the UART devices unconditionally
When using the Magnum ARC firmware we can see accesses to the
UART1 being rejected, because the device is not mapped:

  $ qemu-system-mips64el -M magnum -d guest_errors,unimp -bios NTPROM.RAW
  Invalid access at addr 0x80007004, size 1, region '(null)', reason: rejected
  Invalid access at addr 0x80007001, size 1, region '(null)', reason: rejected
  Invalid access at addr 0x80007002, size 1, region '(null)', reason: rejected
  Invalid access at addr 0x80007003, size 1, region '(null)', reason: rejected
  Invalid access at addr 0x80007004, size 1, region '(null)', reason: rejected

Since both UARTs are present (soldered on the board) regardless
of whether there are character devices connected, map them
unconditionally.

(This code pre-dated commit 12051d82f0 which made it safe to pass
NULL in as a chardev to serial devices.)

The MIPS magnum machines are available in both big endian (mips64) and little
endian (mips64el) configurations. Ensure that the dp893x big_endian property
is set accordingly using logic similar to that used for the MIPS malta
machines.

5ee0abed51 clock: Add ClockEvent parameter to callbacks
The Clock framework allows users to specify a callback which is
called after the clock's period has been updated.  Some users need to
also have a callback which is called before the clock period is
updated.

As the first step in adding support for notifying Clock users on
pre-update events, add an argument to the ClockCallback to specify
what event is being notified, and add an argument to the various
functions for registering a callback to specify which events are
of interest to that callback.

Note that the documentation update renders correct the previously
incorrect claim in 'Adding a new clock' that callbacks "will be
explained in a following section".

3dc31cb849 vt82c686: Move creation of ISA devices to the ISA bridge
Currently the ISA devices that are part of the VIA south bridge,
superio chip are wired up by board code. Move creation of these ISA
devices to the VIA ISA bridge model so that board code does not need
to access ISA bus. This also allows vt82c686b-superio to be made
internal to vt82c686 which allows implementing its configuration via
registers in subseqent commits.

911629e6d3 vt82c686: Fix SMBus IO base and configuration registers
The base address of the SMBus io ports and its enabled status is set
by registers in the PCI config space but this was not correctly
emulated. Instead the SMBus registers were mapped on realize to the
base address set by a property to the address expected by fuloong2e
firmware.

Fix the base and config register handling to more closely model
hardware which allows to remove the property and allows the guest to
control this mapping. Do all this in reset instead of realize so it's
correctly updated on reset.

7827168471 cpu: tcg_ops: move to tcg-cpu-ops.h, keep a pointer in CPUClass
we cannot in principle make the TCG Operations field definitions
conditional on CONFIG_TCG in code that is included by both common_ss
and specific_ss modules.

Therefore, what we can do safely to restrict the TCG fields to TCG-only
builds, is to move all tcg cpu operations into a separate header file,
which is only included by TCG, target-specific code.

This leaves just a NULL pointer in the cpu.h for the non-TCG builds.

This also tidies up the code in all targets a bit, having all TCG cpu
operations neatly contained by a dedicated data struct.

c76b409fef 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.

f169413c27 hw/mips: Remove the 'r4k' machine
We deprecated the support for the 'r4k' machine for the 5.0 release
(commit d32dc61421), which means that our deprecation policy allows
us to drop it in release 5.2. Remove the code.

To repeat the rationale from the deprecation note:
- this virtual machine has no specification
- the Linux kernel dropped support for it 10 years ago

Users are recommended to use the Malta board instead.

cf3d932f97 hw/mips/mipssim: Use MMIO serial device on fake ISA I/O
The 'mipssim' is not a real hardware, it is a simulator.

There is an ISA MMIO space mapped at 0x1fd00000, however
this is not a real ISA bus (no ISA IRQ). So can not use
the TYPE_ISA_SERIAL device...
Instead we have been using a plain MMIO device, but named
it IO.

TYPE_SERIAL_IO is a subset of TYPE_SERIAL_MM, using
regshift=0 and endianness=DEVICE_LITTLE_ENDIAN.

Directly use the TYPE_SERIAL_MM device, enforcing the
regshift/endianness values. 'regshift' default is already
'0'. 'endianness' is meaningless for 8-bit accesses.

This change breaks migration back compatibility, but
this is not an issue for the mipssim machine.

Several callers of load_elf() pass pointers for lowaddr and highaddr
parameters which are then not used for anything. This may stem from a
misunderstanding that load_elf need a value here but in fact it can
take NULL to ignore these values. Remove such unused variables and
pass NULL instead from callers that don't need these.

b15e402fc8 trace-events: Fix attribution of trace points to source
Some trace points are attributed to the wrong source file.  Happens
when we neglect to update trace-events for code motion, or add events
in the wrong place, or misspell the file name.

Clean up with help of scripts/cleanup-trace-events.pl.  Funnies
requiring manual post-processing:

* accel/tcg/cputlb.c trace points are in trace-events.

* block.c and blockdev.c trace points are in block/trace-events.

* hw/block/nvme.c uses the preprocessor to hide its trace point use
  from cleanup-trace-events.pl.

* hw/tpm/tpm_spapr.c uses pseudo trace point tpm_spapr_show_buffer to
  guard debug code.

* include/hw/xen/xen_common.h trace points are in hw/xen/trace-events.

* linux-user/trace-events abbreviates a tedious list of filenames to
  */signal.c.

* net/colo-compare and net/filter-rewriter.c use pseudo trace points
  colo_compare_miscompare and colo_filter_rewriter_debug to guard
  debug code.

db1015e92e Move QOM typedefs and add missing includes
Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.

Patch generated using:

 $ ./scripts/codeconverter/converter.py -i \
   --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')

which will split "typdef struct { ... } TypedefName"
declarations.

Followed by:

 $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
    $(git grep -l '' -- '*.[ch]')

which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

Displaying "vt82c686b_init error" doesn't give any hint about why
this call failed. As this message targets developers and not users,
replace the pointless error message by a call to assert() which

feabc71dfa configure: do not include dependency flags in QEMU_CFLAGS and LIBS
All Meson executables should specify their dependencies explicitly, either
directly or indirectly via declare_dependency.  Makefiles instead did
not propagate dependencies correctly from static libraries, for example.
Therefore, flags for dependencies need not be included in QEMU_CFLAGS.
LIBS is not used at all, so drop that one as well.

In a few cases the dependencies were not yet specified, so add them.

102ca9667d mips/cps: Use start-powered-off CPUState property
Instead of setting CPUState::halted to 1 in main_cpu_reset(), use the
start-powered-off property which makes cpu_common_reset() initialize it
to 1 in common code.

Also change creation of CPU object from cpu_create() to object_new() and
qdev_realize_and_unref() because cpu_create() realizes the CPU and it's not
possible to set a property after the object is realized.

243af0225a trace: switch position of headers to what Meson requires
Meson doesn't enjoy the same flexibility we have with Make in choosing
the include path.  In particular the tracing headers are using
$(build_root)/$(<D).

In order to keep the include directives unchanged,
the simplest solution is to generate headers with patterns like
"trace/trace-audio.h" and place forwarding headers in the source tree
such that for example "audio/trace.h" includes "trace/trace-audio.h".

This patch is too ugly to be applied to the Makefiles now.  It's only
a way to separate the changes to the tracing header files from the
Meson rewrite of the tracing logic.

Not exactly elegant, I'm afraid.

The "when != lbl:" is necessary to avoid transforming

         if (fun(args, &err)) {
             goto out
         }
         ...
     out:
         error_propagate(errp, err);

even though other paths to label out still need the error_propagate().
For an actual example, see sclp_realize().

Without the "when strict", Coccinelle transforms vfio_msix_setup(),
incorrectly.  I don't know what exactly "when strict" does, only that
it helps here.

The match of return is narrower than what I want, but I can't figure
out how to express "return where the operand doesn't use @err".  For
an example where it's too narrow, see vfio_intx_enable().

Silently fails to convert hw/arm/armsse.c, because Coccinelle gets
confused by ARMSSE being used both as typedef and function-like macro
there.  Converted manually.

Line breaks tidied up manually.  One nested declaration of @local_err
deleted manually.  Preexisting unwanted blank line dropped in
hw/riscv/sifive_e.c.

81f66cfd24 mips/cps: Fix mips_cps_realize() error API violations
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.

mips_cps_realize() is wrong that way: it passes &err to multiple
object_property_set_FOO() without checking for failure, and then to
sysbus_realize().  Harmless, because the object_property_set_FOO()
can't actually fail here.

Fix by passing &error_abort instead.

The first rule exempts hw/arm/highbank.c, because it matches along two
control flow paths there, with different @type_name.  Covered by the
next commit's manual conversions.

932d3a65c8 mips/boston: Fix boston_mach_init() error handling
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.

boston_mach_init() is wrong that way.  The last calls treats an error
as fatal.  Do that for the prior ones, too.

f26740c61a smbus: Fix spd_data_generate() error API violation
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.

be1765f398 hw/ide: Do ide_drive_get() within pci_ide_create_devs()
The pci_ide_create_devs() function takes a hd_table parameter but all
callers just pass what ide_drive_get() returns so we can do it locally
simplifying callers and removing hd_table parameter.
