9d9db41373 tcg/riscv: Use tcg_pcrel_diff in tcg_out_ldst
We failed to update this with the w^x split, so misses the fact
that true pc-relative offsets are usually small.

e471a8c985 target/riscv: Trap on writes to stimecmp from VS when hvictl.VTI=1
Per the AIA specification, writes to stimecmp from VS level should
trap when hvictl.VTI is set since the write may cause vsip.STIP to

06d85c24c2 target/riscv: Fix up masking of vsip/vsie accesses
The current logic attempts to shift the VS-level bits into their correct
position in mip while leaving the remaining bits in-tact. This is both
pointless and likely incorrect since one would expect that any new, future
VS-level interrupts will get their own position in mip rather than sharing
with their (H)S-level equivalent. Fix this, and make the logic more
readable, by just making off the VS-level bits and shifting them into
position.

This also fixes reads of vsip, which would only ever report vsip.VSSIP
since the non-writable bits got masked off as well.

914c97f968 hw/riscv/virt.c: remove 'is_32_bit' param from create_fdt_socket_cpus()
create_fdt_socket_cpus() writes a different 'mmu-type' value if we're
running in 32 or 64 bits. However, the flag is being calculated during
virt_machine_init(), and is passed around in create_fdt(), then
create_fdt_socket(), and then finally create_fdt_socket_cpus(). None of
the intermediate functions are using the flag, which is a bit
misleading.

Remove 'is_32_bit' flag from create_fdt_socket_cpus() and calculate it
using the already available RISCVVirtState pointer. This will also
change the signature of create_fdt_socket() and create_fdt(), making it
clear that these functions don't do anything special when we're running
in 32 bit mode.

5ab1095213 target/riscv/cpu.c: do not skip misa logic in riscv_cpu_realize()
All RISCV CPUs are setting cpu->cfg during their cpu_init() functions,
meaning that there's no reason to skip all the misa validation and setup
if misa_ext was set beforehand - especially since we're setting an
updated value in set_misa() in the end.

Put this code chunk into a new riscv_cpu_validate_set_extensions()
helper and always execute it regardless of what the board set in
env->misa_ext.

This will put more responsibility in how each board is going to init
their attributes and extensions if they're not using the defaults.
It'll also allow realize() to do its job looking only at the extensions
enabled per se, not corner cases that some CPUs might have, and we won't
have to change multiple code paths to fix or change how extensions work.

c66ffcd535 target/riscv/cpu: set cpu->cfg in register_cpu_props()
There is an informal contract between the cpu_init() functions and
riscv_cpu_realize(): if cpu->env.misa_ext is zero, assume that the
default settings were loaded via register_cpu_props() and do validations
to set env.misa_ext. If it's not zero, skip this whole process and
assume that the board somehow did everything.

At this moment, all SiFive CPUs are setting a non-zero misa_ext during
their cpu_init() and skipping a good chunk of riscv_cpu_realize().  This
causes problems when the code being skipped in riscv_cpu_realize()
contains fixes or assumptions that affects all CPUs, meaning that SiFive
CPUs are missing out.

To allow this code to not be skipped anymore, all the cpu->cfg.ext_*
attributes needs to be set during cpu_init() time. At this moment this
is being done in register_cpu_props(). The SiFive boards are setting
their own extensions during cpu_init() though, meaning that they don't
want all the defaults from register_cpu_props().

Let's move the contract between *_cpu_init() and riscv_cpu_realize() to
register_cpu_props(). Inside this function we'll check if
cpu->env.misa_ext was set and, if that's the case, set all relevant
cpu->cfg.ext_* attributes, and only that. Leave the 'misa_ext' = 0 case
as is today, i.e. loading all the defaults from riscv_cpu_extensions[].

register_cpu_props() can then be called by all the cpu_init() functions,
including the SiFive ones. This will make all CPUs behave more in line
with what riscv_cpu_realize() expects.

This will also make the cpu_init() functions even more alike, but at this
moment we would need some design changes in how we're initializing
extensions/attributes (e.g. some CPUs are setting cfg options after
register_cpu_props(), so we can't simply add the function to a common
post_init() hook)  to make a common cpu_init() code across all CPUs.

b9a65476cb hw/riscv: write initrd 'chosen' FDT inside riscv_load_initrd()
riscv_load_initrd() returns the initrd end addr while also writing a
'start' var to mark the addr start. These informations are being used
just to write the initrd FDT node. Every existing caller of
riscv_load_initrd() is writing the FDT in the same manner.

We can simplify things by writing the FDT inside riscv_load_initrd(),
sparing callers from having to manage start/end addrs to write the FDT
themselves.

An 'if (fdt)' check is already inserted at the end of the function
because we'll end up using it later on with other boards that doesn´t
have a FDT.

RISCV32_BIOS_BIN firmware with minimal options.

The riscv32 'spike' machine isn't bootable at this moment, requiring an
OpenSBI fix [1] and QEMU side changes [2]. We could just leave at that
or add a 'skip' test to remind us about it. To work as a reminder that
we have a riscv32 'spike' test that should be enabled as soon as OpenSBI
QEMU rom receives the fix, we're adding a 'skip' test:

71d68c48be hw/riscv: spike: Decouple create_fdt() dependency to ELF loading

whether to insert a <reg> property for the HTIF. This unfortunately
creates a hidden dependency to riscv_load_{firmware,kernel} that
create_fdt() must be called after the ELF {firmware,kernel} image
has been loaded.

Decouple such dependency be adding a new parameter to create_fdt(),
whether custom HTIF base address is used. The flag will be set if
non ELF {firmware,kernel} image is given by user.

9d3f7108bc hw/riscv/boot.c: introduce riscv_default_firmware_name()
Some boards are duplicating the 'riscv_find_and_load_firmware' call
because the 32 and 64 bits images have different names. Create
a function to handle this detail instead of hardcoding it in the boards.

Ideally we would bake this logic inside riscv_find_and_load_firmware(),
or even create a riscv_load_default_firmware(), but at this moment we
cannot infer whether the machine is running 32 or 64 bits without
accessing RISCVHartArrayState, which in turn can't be accessed via the
common code from boot.c. In the end we would exchange 'firmware_name'
for a flag with riscv_is_32bit(), which isn't much better than what we
already have today.

a8a7f680d2 hw/riscv: spike: Remove the out-of-date comments
Spike machine now supports OpenSBI plain binary bios image, so the
comments are no longer valid.

a6e13e31d5 hw/char: riscv_htif: Support console output via proxy syscall
At present the HTIF proxy syscall is unsupported. On RV32, only
device 0 is supported so there is no console device for RV32.
The only way to implement console funtionality on RV32 is to
support the SYS_WRITE syscall.

With this commit, the Spike machine is able to boot the 32-bit
OpenSBI generic image.

753ae97abc hw/char: riscv_htif: Avoid using magic numbers
The Spike HTIF is poorly documented. The only relevant info we can
get from the internet is from Andrew Waterman at [1].

Add a comment block before htif_handle_tohost_write() to explain
the tohost register format, and use meaningful macros instead of
magic numbers in the codes.

While we are here, correct 2 multi-line comment blocks that have
wrong format.

34d55725e6 ui/spice: Require spice-server >= 0.14.0
Version 0.14.0 is now old enough to have made it into the major
distributions:

     Debian 11: 0.14.3
     RHEL-8: 0.14.3
     FreeBSD (ports): 0.15.0
     Fedora 35: 0.15.0
     Ubuntu 20.04: 0.14.2
     OpenSUSE Leap 15.3: 0.14.3

Requiring it lets us drop a number of version checks.  The next commit
will clean up some more.

f4c1bcb8c4 Revert "hmp: info spice: take out webdav"
This reverts commit 7c6044a94e.

We had to take it out because SPICE_CHANNEL_WEBDAV requires
spice-protocol 0.12.7, but we had only 0.12.3.  We have 0.14.0 now, so
put it back in.
