I think they're all pretty safe and worth having in rc3.

New patch
1
cpu.h has a lot of #defines relating to CPU register fields.
2
Most of these aren't actually used outside target/arm code,
3
so there's no point in cluttering up the cpu.h file with them.
4
Move some easy ones to internals.h.

The timer _EL02 registers should UNDEF for invalid accesses from EL2
2
or EL3 when HCR_EL2.E2H == 0, not take a cp access trap. We were
3
delivering the exception to EL2 with the wrong syndrome.

Don't allow the guest to write CNTHCTL_EL2 bits which don't exist.
2
This is not strictly architecturally required, but it is how we've
3
tended to implement registers more recently.

In particular, bits [19:18] are only present with FEAT_RME,
6
and bits [17:12] will only be present with FEAT_ECV.

New patch
1
The functionality defined by ID_AA64MMFR0_EL1.ECV == 1 is:
2
* four new trap bits for various counter and timer registers
3
* the CNTHCTL_EL2.EVNTIS and CNTKCTL_EL1.EVNTIS bits which control
4
scaling of the event stream. This is a no-op for us, because we don't
5
implement the event stream (our WFE is a NOP): all we need to do is
6
allow CNTHCTL_EL2.ENVTIS to be read and written.
7
* extensions to PMSCR_EL1.PCT, PMSCR_EL2.PCT, TRFCR_EL1.TS and
8
TRFCR_EL2.TS: these are all no-ops for us, because we don't implement
9
FEAT_SPE or FEAT_TRF.
10
* new registers CNTPCTSS_EL0 and NCTVCTSS_EL0 which are
11
"self-sychronizing" views of the CNTPCT_EL0 and CNTVCT_EL0, meaning
12
that no barriers are needed around their accesses. For us these
13
are just the same as the normal views, because all our sysregs are
14
inherently self-sychronizing.
1
15
16
In this commit we implement the trap handling and permit the new
17
CNTHCTL_EL2 bits to be written.

New patch
1
For FEAT_ECV, new registers CNTPCTSS_EL0 and CNTVCTSS_EL0 are
2
defined, which are "self-synchronized" views of the physical and
3
virtual counts as seen in the CNTPCT_EL0 and CNTVCT_EL0 registers
4
(meaning that no barriers are needed around accesses to them to
5
ensure that reads of them do not occur speculatively and out-of-order
6
with other instructions).
1
7
8
For QEMU, all our system registers are self-synchronized, so we can
9
simply copy the existing implementation of CNTPCT_EL0 and CNTVCT_EL0
10
to the new register encodings.
11
12
This means we now implement all the functionality required for
13
ID_AA64MMFR0_EL1.ECV == 0b0001.

1
When ID_AA64MMFR0_EL1.ECV is 0b0010, a new register CNTPOFF_EL2 is
2
implemented. This is similar to the existing CNTVOFF_EL2, except
3
that it controls a hypervisor-adjustable offset made to the physical
4
counter and timer.

Implement the handling for this register, which includes control/trap
7
bits in SCR_EL3 and CNTHCTL_EL2.

- Alternate Function and Analog mode aren't implemented :
13
suppressing the field in realize means we won't re-introduce this bug
15
pins in AF/Analog behave like pins in input mode
14
when we add other CPUs that have SPE in hardware, such as the
16
- floating pins stay at their last value
15
Neoverse-V1.)
17
- register IDR reset values differ from the real one :
18
values are coherent with the other registers reset values
19
and the fact that AF/Analog modes aren't implemented
20
- setting I/O output speed isn't supported
21
- locking port bits isn't supported
22
- ADC function isn't supported
23
- GPIOH has 16 pins instead of 2 pins
24
- writing to registers LCKR, AFRL, AFRH and ASCR is ineffective

Commit 06680b15b4 moved qemu_*_exec_dir() to cutils but forgot
3
The testcase contains :
4
to move the macOS dyld(3) include, resulting in the following
4
- `test_idr_reset_value()` :
5
error (when building with Homebrew GCC on macOS Monterey 12.4):
5
Checks the reset values of MODER, OTYPER, PUPDR, ODR and IDR.
6
- `test_gpio_output_mode()` :
7
Checks that writing a bit in register ODR results in the corresponding
8
pin rising or lowering, if this pin is configured in output mode.
9
- `test_gpio_input_mode()` :
10
Checks that a input pin set high or low externally results
11
in the pin rising and lowering.
12
- `test_pull_up_pull_down()` :
13
Checks that a floating pin in pull-up/down mode is actually high/down.
14
- `test_push_pull()` :
15
Checks that a pin set externally is disconnected when configured in
16
push-pull output mode, and can't be set externally while in this mode.
17
- `test_open_drain()` :
18
Checks that a pin set externally high is disconnected when configured
19
in open-drain output mode, and can't be set high while in this mode.
20
- `test_bsrr_brr()` :
21
Checks that writing to BSRR and BRR has the desired result in ODR.
22
- `test_clock_enable()` :
23
Checks that GPIO clock is at the right frequency after enabling it.

With the introduction of the new TCG GICv4, build_madt() is badly broken
3
While the 8-bit input elements are sequential in the input vector,

as we do not present any GIC Redistributor structure in MADT for GICv4
4
the 32-bit output elements are not sequential in the output matrix.
5
guests, so that they have no idea about where the Redistributor

Do not attempt to compute 2 32-bit outputs at the same time.

register frames are. This fixes a Linux guest crash at boot time with
