A large arm pullreq, mostly because of 3 series:
1
First arm pullreq of the cycle; this is mostly my softfloat NaN
2
* aspeed 2600 support
2
handling series. (Lots more in my to-review queue, but I don't
3
* semihosting v2.0 support
3
like pullreqs growing too close to a hundred patches at a time :-))
4
* transaction-based ptimers

3
Add trace events for read/write accesses and IRQ.
3
imx_fec models the same PHY as lan9118_phy. The code is almost the same with
4
imx_fec having more logging and tracing. Merge these improvements into
5
lan9118_phy and reuse in imx_fec to fix the code duplication.
4

5
Properties are structures used for the ARM particular MBOX.
7
Some migration state how resides in the new device model which breaks migration
6
Since one call in bcm2835_property.c concerns the mbox block,
8
compatibility for the following machines:
7
name this trace event in the same bcm2835_mbox* namespace.

IEC binary prefixes ease code review: the unit is explicit.

The real device advertises this mode and the device model already advertises
4
100 mbps half duplex and 10 mbps full+half duplex. So advertise this mode to
5
make the model more realistic.

For IEEE fused multiply-add, the (0 * inf) + NaN case should raise
2
Invalid for the multiplication of 0 by infinity. Currently we handle
3
this in the per-architecture ifdef ladder in pickNaNMulAdd().
4
However, since this isn't really architecture specific we can hoist
5
it up to the generic code.

The AST2600 SoC has an extra controller to set the PHY registers.
7
For the cases where the infzero test in pickNaNMulAdd was
8
returning 2, we can delete the check entirely and allow the
9
code to fall into the normal pick-a-NaN handling, because this
10
will return 2 anyway (input 'c' being the only NaN in this case).
11
For the cases where infzero was returning 3 to indicate "return
12
the default NaN", we must retain that "return 3".

For Arm, this looks like it might be a behaviour change because we

Message-id: 20190925143248.10000-23-clg@kaod.org
16
a quiet NaN. However, it is not, because Arm target code never looks
17
at float_flag_invalid_imz, and for the (0 * inf) + SNaN case we
18
already raised float_flag_invalid via the "abc_mask &
19
float_cmask_snan" check in pick_nan_muladd.
20
21
For any target architecture using the "default implementation" at the
22
bottom of the ifdef, this is a behaviour change but will be fixing a
23
bug (where we failed to raise the Invalid exception for (0 * inf +
24
QNaN). The architectures using the default case are:
25
* hppa
26
* i386
27
* sh4
28
* tricore
29
30
The x86, Tricore and SH4 CPU architecture manuals are clear that this
31
should have raised Invalid; HPPA is a bit vaguer but still seems
32
clear enough.

If the target sets default_nan_mode then we're always going to return

ptimers to the new transaction-based ptimer API. This just requires

the default NaN, and pickNaNMulAdd() no longer has any side effects.

When we convert pickNaNMulAdd() to allow runtime selection of the NaN
7
propagation rule, this means we won't have to make the targets which
8
use default_nan_mode also set a propagation rule.

10
Since RiscV always uses default_nan_mode, this allows us to remove
11
its ifdef case from pickNaNMulAdd().

Factor out the implementation of SYS_ISTTY via the new function
1
IEEE 758 does not define a fixed rule for what NaN to return in
2
tables.
2
the case of a fused multiply-add of inf * 0 + NaN. Different
3
architectures thus do different things:
4
* some return the default NaN
5
* some return the input NaN
6
* Arm returns the default NaN if the input NaN is quiet,
7
and the input NaN if it is signalling
8
9
We want to make this logic be runtime selected rather than
10
hardcoded into the binary, because:
11
* this will let us have multiple targets in one QEMU binary
12
* the Arm FEAT_AFP architectural feature includes letting
13
the guest select a NaN propagation rule at runtime
14
15
In this commit we add an enum for the propagation rule, the field in
16
float_status, and the corresponding getters and setters. We change
17
pickNaNMulAdd to honour this, but because all targets still leave
18
this field at its default 0 value, the fallback logic will pick the
19
rule type with the old ifdef ladder.
20
21
Note that four architectures both use the muladd softfloat functions
22
and did not have a branch of the ifdef ladder to specify their
23
behaviour (and so were ending up with the "default" case, probably
24
wrongly): i386, HPPA, SH4 and Tricore. SH4 and Tricore both set
25
default_nan_mode, and so will never get into pickNaNMulAdd(). For
26
HPPA and i386 we retain the same behaviour as the old default-case,
27
which is to not ever return the default NaN. This might not be
28
correct but it is not a behaviour change.

Version 2.0 of the semihosting specification added support for
1
Set the FloatInfZeroNaNRule explicitly for the MIPS target,
2
allowing a guest to detect whether the implementation supported
2
so we can remove the ifdef from pickNaNMulAdd().
3
particular features. This works by the guest opening a magic
4
file ":semihosting-features", which contains a fixed set of
5
data with some magic numbers followed by a sequence of bytes
6
with feature flags. The file is expected to behave sensibly
7
for the various semihosting calls which operate on files
8
(SYS_FLEN, SYS_SEEK, etc).
9
10
Implement this as another kind of guest FD using our function
11
table dispatch mechanism. Initially we report no extended
12
features, so we have just one feature flag byte which is zero.

The semihosting code needs accuss to the linux-user only
1
Set the FloatInfZeroNaNRule explicitly for the HPPA target,
2
TaskState pointer so it can set the semihosting errno per-thread
2
so we can remove the ifdef from pickNaNMulAdd().
3
for linux-user mode. At the moment we do this by having some
4
ifdefs so that we define a 'ts' local in do_arm_semihosting()
5
which is either a real TaskState * or just a CPUARMState *,
6
depending on which mode we're compiling for.
7
3
8
This is awkward if we want to refactor do_arm_semihosting()
4
As this is the last target to be converted to explicitly setting
9
into other functions which might need to be passed the TaskState.
5
the rule, we can remove the fallback code in pickNaNMulAdd()
10
Restrict usage of the TaskState local by:
6
entirely.
11
* making set_swi_errno() always take the CPUARMState pointer
12
and (for the linux-user version) get TaskState from that
13
* creating a new get_swi_errno() which reads the errno
14
* having the two semihosting calls which need the TaskState
15
for other purposes (SYS_GET_CMDLINE and SYS_HEAPINFO)
16
define a variable with scope restricted to just that code

Switch the cmsdk-apb-timer code away from bottom-half based ptimers
1
The new implementation of pickNaNMulAdd() will find it convenient
2
to the new transaction-based ptimer API. This just requires adding
2
to know whether at least one of the three arguments to the muladd
3
begin/commit calls around the various places that modify the ptimer
3
was a signaling NaN. We already calculate that in the caller,
4
state, and using the new ptimer_init() function to create the timer.
4
so pass it in as a new bool have_snan.

Switch the arm_mptimer.c code away from bottom-half based ptimers to
1
IEEE 758 does not define a fixed rule for which NaN to pick as the
2
the new transaction-based ptimer API. This just requires adding
2
result if both operands of a 3-operand fused multiply-add operation

begin/commit calls around the various places that modify the ptimer

are NaNs. As a result different architectures have ended up with

4
different rules for propagating NaNs.
5
6
QEMU currently hardcodes the NaN propagation logic into the binary
7
because pickNaNMulAdd() has an ifdef ladder for different targets.
8
We want to make the propagation rule instead be selectable at
9
runtime, because:
10
* this will let us have multiple targets in one QEMU binary
11
* the Arm FEAT_AFP architectural feature includes letting
12
the guest select a NaN propagation rule at runtime
13
14
In this commit we add an enum for the propagation rule, the field in
15
float_status, and the corresponding getters and setters. We change
16
pickNaNMulAdd to honour this, but because all targets still leave
17
this field at its default 0 value, the fallback logic will pick the
18
rule type with the old ifdef ladder.
19
20
It's valid not to set a propagation rule if default_nan_mode is
21
enabled, because in that case there's no need to pick a NaN; all the
22
callers of pickNaNMulAdd() catch this case and skip calling it.

New patch
1
Explicitly set a rule in the softfloat tests for propagating NaNs in
2
the muladd case. In meson.build we put -DTARGET_ARM in fpcflags, and
3
so we should select here the Arm rule of float_3nan_prop_s_cab.

Set the Float3NaNPropRule explicitly for i386. We had no
2
i386-specific behaviour in the old ifdef ladder, so we were using the
3
default "prefer a then b then c" fallback; this is actually the
4
correct per-the-spec handling for i386.

Switch the mss-timer code away from bottom-half based ptimers to
1
Set the Float3NaNPropRule explicitly for HPPA, and remove the
2
the new transaction-based ptimer API. This just requires adding
2
ifdef from pickNaNMulAdd().
3
begin/commit calls around the various places that modify the ptimer
3
4
state, and using the new ptimer_init() function to create the timer.
4
HPPA is the only target that was using the default branch of the
5
ifdef ladder (other targets either do not use muladd or set
6
default_nan_mode), so we can remove the ifdef fallback entirely now
7
(allowing the "rule not set" case to fall into the default of the
8
switch statement and assert).
9
10
We add a TODO note that the HPPA rule is probably wrong; this is
11
not a behavioural change for this refactoring.

From: Joel Stanley <joel@jms.id.au>
1
Currently m68k_cpu_reset_hold() calls floatx80_default_nan(NULL)
2
to get the NaN bit pattern to reset the FPU registers. This
3
works because it happens that our implementation of
4
floatx80_default_nan() doesn't actually look at the float_status
5
pointer except for TARGET_MIPS. However, this isn't guaranteed,
6
and to be able to remove the ifdef in floatx80_default_nan()
7
we're going to need a real float_status here.
2
8
3
The AST2600 SDMC controller is slightly different from its predecessor
9
Rearrange m68k_cpu_reset_hold() so that we initialize env->fp_status
4
(DRAM training). Max memory is now 2G on the AST2600.
10
earlier, and thus can pass it to floatx80_default_nan().

Currently for the semihosting calls which take a file descriptor
1
We create our 128-bit default NaN by calling parts64_default_nan()
2
(SYS_CLOSE, SYS_WRITE, SYS_READ, SYS_ISTTY, SYS_SEEK, SYS_FLEN)
2
and then adjusting the result. We can do the same trick for creating
3
we have effectively two implementations, one for real host files
3
the floatx80 default NaN, which lets us drop a target ifdef.
4
and one for when we indirect via the gdbstub. We want to add a
5
third one to deal with the magic :semihosting-features file.
6
4
7
Instead of having a three-way if statement in each of these
5
floatx80 is used only by:
8
cases, factor out the implementation of the calls to separate
6
i386
9
functions which we dispatch to via function pointers selected
7
m68k
10
via the GuestFDType for the guest fd.
8
arm nwfpe old floating-point emulation emulation support
9
(which is essentially dead, especially the parts involving floatx80)
10
PPC (only in the xsrqpxp instruction, which just rounds an input
11
value by converting to floatx80 and back, so will never generate
12
the default NaN)
11
13
12
In this commit, we set up the framework for the dispatch,
14
The floatx80 default NaN as currently implemented is:
13
and convert the SYS_CLOSE call to use it.
15
m68k: sign = 0, exp = 1...1, int = 1, frac = 1....1
16
i386: sign = 1, exp = 1...1, int = 1, frac = 10...0
17
18
These are the same as the parts64_default_nan for these architectures.
19
20
This is technically a possible behaviour change for arm linux-user
21
nwfpe emulation emulation, because the default NaN will now have the
22
sign bit clear. But we were already generating a different floatx80
23
default NaN from the real kernel emulation we are supposedly
24
following, which appears to use an all-bits-1 value:
25
https://elixir.bootlin.com/linux/v6.12/source/arch/arm/nwfpe/softfloat-specialize#L267
26
27
This won't affect the only "real" use of the nwfpe emulation, which
28
is ancient binaries that used it as part of the old floating point
29
calling convention; that only uses loads and stores of 32 and 64 bit
30
floats, not any of the floatx80 behaviour the original hardware had.
31
We also get the nwfpe float64 default NaN value wrong:
32
https://elixir.bootlin.com/linux/v6.12/source/arch/arm/nwfpe/softfloat-specialize#L166
33
so if we ever cared about this obscure corner the right fix would be
34
to correct that so nwfpe used its own default-NaN setting rather
35
than the Arm VFP one.

When we are routing semihosting operations through the gdbstub, the
1
In target/loongarch's helper_fclass_s() and helper_fclass_d() we pass
2
work of sorting out the return value and setting errno if necessary
2
a zero-initialized float_status struct to float32_is_quiet_nan() and
3
is done by callback functions which are invoked by the gdbstub code.

float64_is_quiet_nan(), with the cryptic comment "for
4
Clean up some ifdeffery in those functions by having them call
4
snan_bit_is_one".
5
set_swi_errno() to set the semihosting errno.
5
6
This pattern appears to have been copied from target/riscv, where it
7
is used because the functions there do not have ready access to the
8
CPU state struct. The comment presumably refers to the fact that the
9
main reason the is_quiet_nan() functions want the float_state is
10
because they want to know about the snan_bit_is_one config.
11
12
In the loongarch helpers, though, we have the CPU state struct
13
to hand. Use the usual env->fp_status here. This avoids our needing
14
to track that we need to update the initializer of the local
15
float_status structs when the core softfloat code adds new
16
options for targets to configure their behaviour.

In the frem helper, we have a local float_status because we want to
2
execute the floatx80_div() with a custom rounding mode. Instead of
3
zero-initializing the local float_status and then having to set it up
4
with the m68k standard behaviour (including the NaN propagation rule
5
and copying the rounding precision from env->fp_status), initialize
6
it as a complete copy of env->fp_status. This will avoid our having
7
to add new code in this function for every new config knob we add
8
to fp_status.

In the old API the individual update functions generally would

18
call ptimer_trigger() immediately, which would schedule the QEMUBH.
19
In the new API the update functions will instead defer the
20
"set s->next_event and call ptimer_reload()" work to
21
ptimer_transaction_commit().
22
23
Because ptimer_trigger() can now immediately call into the
24
device code which may then call other ptimer functions that
25
update ptimer_state fields, we must be more careful in
26
ptimer_reload() not to cache fields from ptimer_state across
27
the ptimer_trigger() call. (This was harmless with the QEMUBH
28
mechanism as the BH would not be invoked until much later.)
29
30
We use assertions to check that:
31
* the functions modifying ptimer state are not called outside
32
a transaction block
33
* ptimer_transaction_begin() and _commit() calls are paired
34
* the transaction API is not used with a QEMUBH ptimer
35
36
There is some slight repetition of code:
37
* most of the set functions have similar looking "if s->bh
38
call ptimer_reload, otherwise set s->need_reload" code
39
* ptimer_init() and ptimer_init_with_bh() have similar code
40
We deliberately don't try to avoid this repetition, because
41
it will all be deleted when the QEMUBH version of the API
42
is removed.

1
In the helper_compute_fprf functions, we pass a dummy float_status
2
in to the is_signaling_nan() function. This is unnecessary, because
3
we have convenient access to the CPU env pointer here and that
4
is already set up with the correct values for the snan_bit_is_one
5
and no_signaling_nans config settings. is_signaling_nan() doesn't
6
ever update the fp_status with any exception flags, so there is
7
no reason not to use env->fp_status here.
2
8
3
The AST2600 has the same sets of 3.6v gpios as the AST2400 plus an
9
Use env->fp_status instead of the dummy fp_status.
4
addtional two sets of 1.8V gpios.

using a compile-time ifdef ladder. This is awkward for two cases:
3
* for single-QEMU-binary we can't hard-code target-specifics like this
4

(specifically the sign bit is different)

Add a field to float_status to specify the default NaN value; fall

back to the old ifdef behaviour if these are not set.

10
The default NaN value is specified by setting a uint8_t to a
11
pattern corresponding to the sign and upper fraction parts of
12
the NaN; the lower bits of the fraction are set from bit 0 of
13
the pattern.

1
Currently the Arm semihosting code returns the guest file descriptors
1
Set the default NaN pattern explicitly, and remove the ifdef from
2
(handles) which are simply the fd values from the host OS or the
2
parts64_default_nan().
3
remote gdbstub. Part of the semihosting 2.0 specification requires
4
that we implement special handling of opening a ":semihosting-features"
5
filename. Guest fds which result from opening the special file
6
won't correspond to host fds, so to ensure that we don't end up
7
with duplicate fds we need to have QEMU code control the allocation
8
of the fd values we give the guest.
9
10
Add in an abstraction layer which lets us allocate new guest FD
11
values, and translate from a guest FD value back to the host one.
12
This also fixes an odd hole where a semihosting guest could
13
use the semihosting API to read, write or close file descriptors
14
that it had never allocated but which were being used by QEMU itself.
15
(This isn't a security hole, because enabling semihosting permits
16
the guest to do arbitrary file access to the whole host filesystem,
17
and so should only be done if the guest is completely trusted.)
18
19
Currently the only kind of guest fd is one which maps to a
20
host fd, but in a following commit we will add one which maps
21
to the :semihosting-features magic data.
22
23
If the guest is migrated with an open semihosting file descriptor
24
then subsequent attempts to use the fd will all fail; this is
25
not a change from the previous situation (where the host fd
26
being used on the source end would not be re-opened on the
27
destination end).

In arm_gdb_syscall() we have a comment suggesting a race
1
Set the default NaN pattern explicitly for m68k.
2
because the syscall completion callback might not happen
3
before the gdb_do_syscallv() call returns. The comment is
4
correct that the callback may not happen but incorrect about
5
the effects. Correct it and note the important caveat that
6
callers must never do any work of any kind after return from
7
arm_gdb_syscall() that depends on its return value.

1
Set the default NaN pattern explicitly for SPARC, and remove
2
the new transaction-based ptimer API. The MCT is complicated
2
the ifdef from parts64_default_nan.
3
and uses multiple different ptimers, so it's clearer to switch
4
it a piece at a time. Here we change over only the GFRC.

Currently the ptimer design uses a QEMU bottom-half as its
1
Set the default NaN pattern explicitly for xtensa.
2
mechanism for calling back into the device model using the
3
ptimer when the timer has expired. Unfortunately this design
4
is fatally flawed, because it means that there is a lag
5
between the ptimer updating its own state and the device
6
callback function updating device state, and guest accesses
7
to device registers between the two can return inconsistent
8
device state.
9
10
We want to replace the bottom-half design with one where
11
the guest device's callback is called either immediately
12
(when the ptimer triggers by timeout) or when the device
13
model code closes a transaction-begin/end section (when the
14
ptimer triggers because the device model changed the
15
ptimer's count value or other state). As the first step,
16
rename ptimer_init() to ptimer_init_with_bh(), to free up
17
the ptimer_init() name for the new API. We can then convert
18
all the ptimer users away from ptimer_init_with_bh() before
19
removing it entirely.
20

(Commit created with
22
git grep -l ptimer_init | xargs sed -i -e 's/ptimer_init/ptimer_init_with_bh/'
23
and three overlong lines folded by hand.)

2
from a host system call, so that we can return -1 from the
3
semihosting function and later allow the guest to get a more
4
specific error code with the SYS_ERRNO function. It comes in
5
two versions, one for user-only and one for softmmu. We forgot
6
to capture the errno in the softmmu version; fix the error.
7
8
(Semihosting calls directed to gdb are unaffected because
9
they go through a different code path that captures the
10
error return from the gdbstub call in arm_semi_cb() or
11
arm_semi_flen_cb().)

Switch the digic-timer.c code away from bottom-half based ptimers to

Now that all our targets have bene converted to explicitly specify

the new transaction-based ptimer API. This just requires adding

their pattern for the default NaN value we can remove the remaining

begin/commit calls around the various places that modify the ptimer
3
fallback code in parts64_default_nan().

It cleanups the current models for the Aspeed AST2400 and AST2500 SoCs

Unpacking and repacking the parts may be slightly more work
4
and prepares ground for future SoCs.

than we did before, but we get to reuse more code. For a
5
code path handling exceptional values, this is an improvement.

The SCU controller on the AST2600 SoC has extra registers. Increase
3
Remember if there was an SNaN, and use that to simplify
4
the number of regs of the model and introduce a new field in the class
4
float_2nan_prop_s_{ab,ba} to only the snan component.
5
to customize the MemoryRegion operations depending on the SoC model.
5
Then, fall through to the corresponding
6
float_2nan_prop_{ab,ba} case to handle any remaining
7
nans, which must be quiet.

Host kernel within [4.18, 5.3] report an erroneous KVM_MAX_VCPUS=512

Replace the "index" selecting between A and B with a result variable

for ARM. The actual capability to instantiate more than 256 vcpus

of the proper type. This improves clarity within the function.

was fixed in 5.4 with the upgrade of the KVM_IRQ_LINE ABI to support
6
vcpu id encoded on 12 bits instead of 8 and a redistributor consuming
7
a single KVM IO device instead of 2.

83
+ * link detected (typically cable is un-plugged). For RX, only a minimal
84
+ * link-detection is available, and for TX the PHY wakes up to send link pulses
85
+ * to avoid any lock-ups in case the peer PHY may also be running in EDPD mode.
86

87
+ * Some PHYs may support configuration of the wake-up interval for TX pulses,
88
+ * and some PHYs may support only disabling TX pulses entirely. For the latter
89
+ * a special value is required (ETHTOOL_PHY_EDPD_NO_TX) so that this can be
90
+ * configured from userspace (should the user want it).
91
+ *
92
+ * The interval units for TX wake-up are in milliseconds, since this should
93
+ * cover a reasonable range of intervals:
94
+ * - from 1 millisecond, which does not sound like much of a power-saver
95
+ * - to ~65 seconds which is quite a lot to wait for a link to come up when
96
