+[PULL 01/14] target/arm: Move some register related defines to internals.h
-From: Philippe Mathieu-Daudé <philmd@linaro.org>
+cpu.h has a lot of #defines relating to CPU register fields.
 Most of these aren't actually used outside target/arm code,
 so there's no point in cluttering up the cpu.h file with them.
 Move some easy ones to internals.h.

+[PULL 04/14] target/arm: Don't allow RES0 CNTHCTL_EL2 bits to be written
-From: Philippe Mathieu-Daudé <philmd@linaro.org>
+Don't allow the guest to write CNTHCTL_EL2 bits which don't exist.
 This is not strictly architecturally required, but it is how we've
 tended to implement registers more recently.
+In particular, bits [19:18] are only present with FEAT_RME,
+and bits [17:12] will only be present with FEAT_ECV.

-[PULL 23/30] target/arm: wrap call to aarch64_sve_change_el in tcg_enabled()
+[PULL 05/14] target/arm: Implement new FEAT_ECV trap bits
-From: Claudio Fontana <cfontana@suse.de>
+The functionality defined by ID_AA64MMFR0_EL1.ECV == 1 is:
  * four new trap bits for various counter and timer registers
  * the CNTHCTL_EL2.EVNTIS and CNTKCTL_EL1.EVNTIS bits which control
    scaling of the event stream. This is a no-op for us, because we don't
    implement the event stream (our WFE is a NOP): all we need to do is
    allow CNTHCTL_EL2.ENVTIS to be read and written.
  * extensions to PMSCR_EL1.PCT, PMSCR_EL2.PCT, TRFCR_EL1.TS and
    TRFCR_EL2.TS: these are all no-ops for us, because we don't implement
    FEAT_SPE or FEAT_TRF.
  * new registers CNTPCTSS_EL0 and NCTVCTSS_EL0 which are
    "self-sychronizing" views of the CNTPCT_EL0 and CNTVCT_EL0, meaning
    that no barriers are needed around their accesses. For us these
    are just the same as the normal views, because all our sysregs are
    inherently self-sychronizing.

-From: Claudio Fontana <cfontana@suse.de>
+For FEAT_ECV, new registers CNTPCTSS_EL0 and CNTVCTSS_EL0 are
 defined, which are "self-synchronized" views of the physical and
 virtual counts as seen in the CNTPCT_EL0 and CNTVCT_EL0 registers
 (meaning that no barriers are needed around accesses to them to
 ensure that reads of them do not occur speculatively and out-of-order
 with other instructions).
-make it clearer from the name that this is a tcg-only function.
+For QEMU, all our system registers are self-synchronized, so we can
 simply copy the existing implementation of CNTPCT_EL0 and CNTVCT_EL0
 to the new register encodings.

 If UPDATE is not set, the write is ignored. This is the only permitted
 behavior in SMMUv3.2 and later.(6.3.14.1 Update procedure)
 As this patch adds a new state to the SMMU (GBPA), it is added
 in a new subsection for forward migration compatibility.
 GBPA is only migrated if its value is different from the reset value.
 It does this to be backward migration compatible if SW didn't write
 the register.

-[PULL 17/30] hw/ssi: Add Nuvoton PSPI Module
+[PULL 09/14] hw/gpio: Implement STM32L4x5 GPIO
-From: Hao Wu <wuhaotsh@google.com>
+From: Inès Varhol <ines.varhol@telecom-paris.fr>
-Nuvoton's PSPI is a general purpose SPI module which enables
+Features supported :
-connections to SPI-based peripheral devices.
+- the 8 STM32L4x5 GPIOs are initialized with their reset values
     (except IDR, see below)
 - input mode : setting a pin in input mode "externally" (using input
     irqs) results in an out irq (transmitted to SYSCFG)
 - output mode : setting a bit in ODR sets the corresponding out irq
     (if this line is configured in output mode)
 - pull-up, pull-down
 - push-pull, open-drain
-Signed-off-by: Hao Wu <wuhaotsh@google.com>
+Difference with the real GPIOs :
-Reviewed-by: Chris Rauer <crauer@google.com>
+- Alternate Function and Analog mode aren't implemented :
-Reviewed-by: Philippe Mathieu-Daude <philmd@linaro.org>
+    pins in AF/Analog behave like pins in input mode
-Message-id: 20230208235433.3989937-3-wuhaotsh@google.com
+- floating pins stay at their last value
 - register IDR reset values differ from the real one :
     values are coherent with the other registers reset values
     and the fact that AF/Analog modes aren't implemented
 - setting I/O output speed isn't supported
 - locking port bits isn't supported
 - ADC function isn't supported
 - GPIOH has 16 pins instead of 2 pins
 - writing to registers LCKR, AFRL, AFRH and ASCR is ineffective

-[PULL 30/30] tests/qtest: Restrict tpm-tis-devices-{swtpm}-test to CONFIG_TCG
+[PULL 11/14] tests/qtest: Add STM32L4x5 GPIO QTest testcase
-From: Fabiano Rosas <farosas@suse.de>
+From: Inès Varhol <ines.varhol@telecom-paris.fr>
-These tests set -accel tcg, so restrict them to when TCG is present.
+The testcase contains :
 - `test_idr_reset_value()` :
 Checks the reset values of MODER, OTYPER, PUPDR, ODR and IDR.
 - `test_gpio_output_mode()` :
 Checks that writing a bit in register ODR results in the corresponding
 pin rising or lowering, if this pin is configured in output mode.
 - `test_gpio_input_mode()` :
 Checks that a input pin set high or low externally results
 in the pin rising and lowering.
 - `test_pull_up_pull_down()` :
 Checks that a floating pin in pull-up/down mode is actually high/down.
 - `test_push_pull()` :
 Checks that a pin set externally is disconnected when configured in
 push-pull output mode, and can't be set externally while in this mode.
 - `test_open_drain()` :
 Checks that a pin set externally high is disconnected when configured
 in open-drain output mode, and can't be set high while in this mode.
 - `test_bsrr_brr()` :
 Checks that writing to BSRR and BRR has the desired result in ODR.
 - `test_clock_enable()` :
 Checks that GPIO clock is at the right frequency after enabling it.

-From: Philippe Mathieu-Daudé <philmd@linaro.org>
+From: Richard Henderson <richard.henderson@linaro.org>
-There is no point in using a void pointer to access the NVIC.
+While the 8-bit input elements are sequential in the input vector,
-Use the real type to avoid casting it while debugging.
+the 32-bit output elements are not sequential in the output matrix.
+Do not attempt to compute 2 32-bit outputs at the same time.

-[PULL 12/30] tests/avocado: retire the Aarch64 TCG tests from boot_linux.py
+Deleted patch
-From: Alex Bennée <alex.bennee@linaro.org>
-The two TCG tests for GICv2 and GICv3 are very heavy weight distros
-that take a long time to boot up, especially for an --enable-debug
-build. The total code coverage they give is:
-  Overall coverage rate:
-    lines......: 11.2% (59584 of 530123 lines)
-    functions..: 15.0% (7436 of 49443 functions)
-    branches...: 6.3% (19273 of 303933 branches)
-We already get pretty close to that with the machine_aarch64_virt
-tests which only does one full boot (~120s vs ~600s) of alpine. We
-expand the kernel+initrd boot (~8s) to test both GICs and also add an
-RNG device and a block device to generate a few IRQs and exercise the
-storage layer. With that we get to a coverage of:
-  Overall coverage rate:
-    lines......: 11.0% (58121 of 530123 lines)
-    functions..: 14.9% (7343 of 49443 functions)
-    branches...: 6.0% (18269 of 303933 branches)
-which I feel is close enough given the massive time saving. If we want
-to target any more sub-systems we can use lighter weight more directed
-tests.

-KVM-only build the 'max' cpu.
-Note that we cannot use 'host' here because the qtests can run without
-any other accelerator (than qtest) and 'host' depends on KVM being
-enabled.

arm_v7m_mmu_idx_all() and arm_v7m_mmu_idx_for_secstate_and_priv()
are only used for system emulation in m_helper.c.
Move the definitions to avoid prototype forward declarations.

Although the 'eabi' field is only used in user emulation where
CPU reset doesn't occur, it doesn't belong to the area to reset.
Move it after the 'end_reset_fields' for consistency.

There is no point in using a void pointer to access the NVIC.
Use the real type to avoid casting it while debugging.

2.34.1

From: Alex Bennée <alex.bennee@linaro.org>

The two TCG tests for GICv2 and GICv3 are very heavy weight distros
that take a long time to boot up, especially for an --enable-debug
build. The total code coverage they give is:

Overall coverage rate:
    lines......: 11.2% (59584 of 530123 lines)
    functions..: 15.0% (7436 of 49443 functions)
    branches...: 6.3% (19273 of 303933 branches)

We already get pretty close to that with the machine_aarch64_virt
tests which only does one full boot (~120s vs ~600s) of alpine. We
expand the kernel+initrd boot (~8s) to test both GICs and also add an
RNG device and a block device to generate a few IRQs and exercise the
storage layer. With that we get to a coverage of:

Overall coverage rate:
    lines......: 11.0% (58121 of 530123 lines)
    functions..: 14.9% (7343 of 49443 functions)
    branches...: 6.0% (18269 of 303933 branches)

which I feel is close enough given the massive time saving. If we want
to target any more sub-systems we can use lighter weight more directed
tests.

2.34.1

From: Mostafa Saleh <smostafa@google.com>

GBPA register can be used to globally abort all
transactions.

It is described in the SMMU manual in "6.3.14 SMMU_GBPA".
ABORT reset value is IMPLEMENTATION DEFINED, it is chosen to
be zero(Do not abort incoming transactions).

Other fields have default values of Use Incoming.

If UPDATE is not set, the write is ignored. This is the only permitted
behavior in SMMUv3.2 and later.(6.3.14.1 Update procedure)

As this patch adds a new state to the SMMU (GBPA), it is added
in a new subsection for forward migration compatibility.
GBPA is only migrated if its value is different from the reset value.
It does this to be backward migration compatible if SW didn't write
the register.

If a test was tagged with the "accel" tag and the specified
accelerator it not present in the qemu binary, cancel the test.

We can now write tests without explicit calls to require_accelerator,
just the tag is enough.

Now that the cortex-a15 is under CONFIG_TCG, use as default CPU for a
KVM-only build the 'max' cpu.

Note that we cannot use 'host' here because the qtests can run without
any other accelerator (than qtest) and 'host' depends on KVM being
enabled.

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

We prefer the FIELD macro over ad-hoc #defines for register bits;
switch CNTHCTL to that style before we add any more bits.

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

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

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

In this commit we implement the trap handling and permit the new
CNTHCTL_EL2 bits to be written.

2.34.1

For FEAT_ECV, new registers CNTPCTSS_EL0 and CNTVCTSS_EL0 are
defined, which are "self-synchronized" views of the physical and
virtual counts as seen in the CNTPCT_EL0 and CNTVCT_EL0 registers
(meaning that no barriers are needed around accesses to them to
ensure that reads of them do not occur speculatively and out-of-order
with other instructions).

For QEMU, all our system registers are self-synchronized, so we can
simply copy the existing implementation of CNTPCT_EL0 and CNTVCT_EL0
to the new register encodings.

This means we now implement all the functionality required for
ID_AA64MMFR0_EL1.ECV == 0b0001.

2.34.1

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

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

2.34.1

From: Inès Varhol <ines.varhol@telecom-paris.fr>

Features supported :
- the 8 STM32L4x5 GPIOs are initialized with their reset values
    (except IDR, see below)
- input mode : setting a pin in input mode "externally" (using input
    irqs) results in an out irq (transmitted to SYSCFG)
- output mode : setting a bit in ODR sets the corresponding out irq
    (if this line is configured in output mode)
- pull-up, pull-down
- push-pull, open-drain

Difference with the real GPIOs :
- Alternate Function and Analog mode aren't implemented :
    pins in AF/Analog behave like pins in input mode
- floating pins stay at their last value
- register IDR reset values differ from the real one :
    values are coherent with the other registers reset values
    and the fact that AF/Analog modes aren't implemented
- setting I/O output speed isn't supported
- locking port bits isn't supported
- ADC function isn't supported
- GPIOH has 16 pins instead of 2 pins
- writing to registers LCKR, AFRL, AFRH and ASCR is ineffective

From: Inès Varhol <ines.varhol@telecom-paris.fr>

The testcase contains :
- `test_idr_reset_value()` :
Checks the reset values of MODER, OTYPER, PUPDR, ODR and IDR.
- `test_gpio_output_mode()` :
Checks that writing a bit in register ODR results in the corresponding
pin rising or lowering, if this pin is configured in output mode.
- `test_gpio_input_mode()` :
Checks that a input pin set high or low externally results
in the pin rising and lowering.
- `test_pull_up_pull_down()` :
Checks that a floating pin in pull-up/down mode is actually high/down.
- `test_push_pull()` :
Checks that a pin set externally is disconnected when configured in
push-pull output mode, and can't be set externally while in this mode.
- `test_open_drain()` :
Checks that a pin set externally high is disconnected when configured
in open-drain output mode, and can't be set high while in this mode.
- `test_bsrr_brr()` :
Checks that writing to BSRR and BRR has the desired result in ODR.
- `test_clock_enable()` :
Checks that GPIO clock is at the right frequency after enabling it.

From: Richard Henderson <richard.henderson@linaro.org>

While the 8-bit input elements are sequential in the input vector,
the 32-bit output elements are not sequential in the output matrix.
Do not attempt to compute 2 32-bit outputs at the same time.

2.34.1

The sun4v RTC device model added under commit a0e893039cf2ce0 in 2016
was unfortunately added with a license of GPL-v3-or-later, which is
not compatible with other QEMU code which has a GPL-v2-only license.

Relicense the code in the .c and the .h file to GPL-v2-or-later,
to make it compatible with the rest of QEMU.

From: Thomas Huth <thuth@redhat.com>

Move the code to a separate file so that we do not have to compile
it anymore if CONFIG_ARM_V7M is not set.
