target/riscv: Fix LMUL check to use VLEN
The previous check was failing with:
VLEN=128 ELEN = 64 SEW = 16 and LMUL = 1/8 which is a
valid combination.
Fix the check to allow valid combinations when VLEN is a multiple of
ELEN.
From the specification:
"In general, the requirement is to support LMUL ≥ SEWMIN/ELEN, where
SEWMIN is the narrowest supported SEW value and ELEN is the widest
supported SEW value. In the standard extensions, SEWMIN=8. For standard
vector extensions with ELEN=32, fractional LMULs of 1/2 and 1/4 must be
supported. For standard vector extensions with ELEN=64, fractional LMULs
of 1/2, 1/4, and 1/8 must be supported." Elsewhere in the specification
it makes clear that VLEN>=ELEN.
From inspection this new check allows:
VLEN=ELEN=64 1/2, 1/4, 1/8 for SEW >=8
VLEN=ELEN=32 1/2, 1/4 for SEW >=8

target/riscv/cpu.c: check priv_ver before auto-enable zca/zcd/zcf
Commit
bd30559568 made changes in how we're checking and disabling
extensions based on env->priv_ver. One of the changes was to move the
extension disablement code to the end of realize(), being able to
disable extensions after we've auto-enabled some of them.
An unfortunate side effect of this change started to happen with CPUs
that has an older priv version, like sifive-u54. Starting on commit
2288a5ce43e5 we're auto-enabling zca, zcd and zcf if RVC is enabled,
but these extensions are priv version 1.12.0. When running a cpu that
has an older priv ver (like sifive-u54) the user is spammed with
warnings like these:
qemu-system-riscv64: warning: disabling zca extension for hart 0x0000000000000000 because privilege spec version does not match
qemu-system-riscv64: warning: disabling zcd extension for hart 0x0000000000000000 because privilege spec version does not match
The warnings are part of the code that disables the extension, but in this
case we're throwing user warnings for stuff that we enabled on our own,
without user intervention. Users are left wondering what they did wrong.
A quick 8.1 fix for this nuisance is to check the CPU priv spec before
auto-enabling zca/zcd/zcf. A more appropriate fix will include a more
robust framework that will account for both priv_ver and user choice
when auto-enabling/disabling extensions, but for 8.1 we'll make it do
with this simple check.
It's also worth noticing that this is the only case where we're
auto-enabling extensions based on a criteria (in this case RVC) that
doesn't match the priv spec of the extensions we're enabling. There's no
need for more 8.1 band-aids.

riscv/disas: Fix disas output of upper immediates
The GNU assembler produces the following output for instructions
with upper immediates:
00002597 auipc a1,0x2
000024b7 lui s1,0x2
6409 lui s0,0x2 # c.lui
The immediate operands of upper immediates are not shifted.
However, the QEMU disassembler prints them shifted:
00002597 auipc a1,8192
000024b7 lui s1,8192
6409 lui s0,8192 # c.lui
The current implementation extracts the immediate bits and shifts the by 12,
so the internal representation of the immediate is the actual immediate.
However, the immediates are later printed using rv_fmt_rd_imm or
rv_fmt_rd_offset, which don't undo the shift.
Let's fix this by using specific output formats for instructions
with upper immediates, that take care of the shift.

block/nvme: invoke blk_io_plug_call() outside q->lock
blk_io_plug_call() is invoked outside a blk_io_plug()/blk_io_unplug()
section while opening the NVMe drive from:
nvme_file_open() ->
nvme_init() ->
nvme_identify() ->
nvme_admin_cmd_sync() ->
nvme_submit_command() ->
blk_io_plug_call()
blk_io_plug_call() immediately invokes the given callback when the
current thread is not plugged, as is the case during nvme_file_open().
Unfortunately, nvme_submit_command() calls blk_io_plug_call() with
q->lock still held:
...
q->sq.tail = (q->sq.tail + 1) % NVME_QUEUE_SIZE;
q->need_kick++;
blk_io_plug_call(nvme_unplug_fn, q);
qemu_mutex_unlock(&q->lock);
^^^^^^^^^^^^^^^^^^^^^^^^^^^
nvme_unplug_fn() deadlocks trying to acquire q->lock because the lock is
already acquired by the same thread. The symptom is that QEMU hangs
during startup while opening the NVMe drive.
Fix this by moving the blk_io_plug_call() outside q->lock. This is safe
because no other thread runs code related to this queue and
blk_io_plug_call()'s internal state is immune to thread safety issues
since it is thread-local.

And to immediately update the surface with the place holder image after

accel/tcg: Zero-pad PC in TCG CPU exec trace lines
In commit
f0a08b0913befbd we changed the type of the PC from
target_ulong to vaddr. In doing so we inadvertently dropped the
zero-padding on the PC in trace lines (the second item inside the []
in these lines). They used to look like this on AArch64, for
instance:
Trace 0: 0x7f2260000100 [
00000000/
0000000040000000/
00000061/
ff200000]
and now they look like this:
Trace 0: 0x7f4f50000100 [
00000000/
40000000/
00000061/
ff200000]
and if the PC happens to be somewhere low like 0x5000
then the field is shown as /5000/.
This is because TARGET_FMT_lx is a "%08x" or "%016x" specifier,
depending on TARGET_LONG_SIZE, whereas VADDR_PRIx is just PRIx64
with no width specifier.
Restore the zero-padding by adding an 016 width specifier to
this tracing and a couple of others that were similarly recently
changed to use VADDR_PRIx without a width specifier.
We can't unfortunately restore the "32-bit guests are padded to
8 hex digits and 64-bit guests to 16 hex digits" behaviour so
easily.

target/arm: Fix S1_ptw_translate() debug path
In commit
fe4a5472ccd6 we rearranged the logic in S1_ptw_translate()
so that the debug-access "call get_phys_addr_*" codepath is used both
when S1 is doing ptw reads from stage 2 and when it is doing ptw
reads from physical memory. However, we didn't update the
calculation of s2ptw->in_space and s2ptw->in_secure to account for
the "ptw reads from physical memory" case. This meant that debug
accesses when in Secure state broke.
Create a new function S2_security_space() which returns the
correct security space to use for the ptw load, and use it to
determine the correct .in_secure and .in_space fields for the
stage 2 lookup for the ptw load.

linux-user: Remove pointless NULL check in clock_adjtime handling
In the code for TARGET_NR_clock_adjtime, we set the pointer phtx to
the address of the local variable htx. This means it can never be
NULL, but later in the code we check it for NULL anyway. Coverity
complains about this (CID
1507683) because the NULL check comes after
a call to clock_adjtime() that assumes it is non-NULL.
Since phtx is always &htx, and is used only in three places, it's not
really necessary. Remove it, bringing the code structure in to line
with that for TARGET_NR_clock_adjtime64, which already uses a simple
'&htx' when it wants a pointer to 'htx'.

We adjust CONFIG_ATOMIC128 and CONFIG_CMPXCHG128 with
CONFIG_ATOMIC128_OPT in atomic128.h. It is difficult
to tell when those changes have been applied with the
ifdef we must use with CONFIG_CMPXCHG128. So instead
use HAVE_CMPXCHG128, which triggers -Werror-undef when
the proper header has not been included.
Improves tcg_gen_atomic_cmpxchg_i128 for s390x host, which
requires CONFIG_ATOMIC128_OPT. Without this we fall back
to EXCP_ATOMIC to single-step 128-bit atomics, which is
slow enough to cause some tests to time out.

linux-user/syscall: Implement execve without execveat
Support for execveat syscall was implemented in 55bbe4 and is available
since QEMU 8.0.0. It relies on host execveat, which is widely available
on most of Linux kernels today.
However, this change breaks qemu-user self emulation, if "host" qemu
version is less than 8.0.0. Indeed, it does not implement yet execveat.
This strange use case happens with most of distribution today having
binfmt support.
With a concrete failing example:
$ qemu-x86_64-7.2 qemu-x86_64-8.0 /bin/bash -c /bin/ls
/bin/bash: line 1: /bin/ls: Function not implemented
-> not implemented means execve returned ENOSYS
qemu-user-static 7.2 and 8.0 can be conveniently grabbed from debian
packages qemu-user-static* [1].
One usage of this is running wine-arm64 from linux-x64 (details [2]).
This is by updating qemu embedded in docker image that we ran into this
issue.
The solution to update host qemu is not always possible. Either it's
complicated or ask you to recompile it, or simply is not accessible
(GitLab CI, GitHub Actions). Thus, it could be worth to implement execve
without relying on execveat, which is the goal of this patch.
This patch was tested with example presented in this commit message.
