-Mostly straightforward bugfixes. The new Xilinx devices are
+The following changes since commit 8f6330a807f2642dc2a3cdf33347aa28a4c00a87:
 arguably 'new feature', but they're fixing a regression where
 our changes to PSCI in commit 3f37979bf mean that EL3 guest
 code now needs to talk to a proper emulated power-controller
 device to turn on secondary CPUs; and it's not yet rc1 and
 they only affect the Xilinx board, so it seems OK to me.

 hard-coded and very outdated list (with just i386 and alpha).  This
 causes two problems.  Firstly, if you build the installer for a
 configuration where you didn't build the i386 binaries you get
 warnings like this:
   warning 6000: unknown variable/constant "{Section_i386}" detected, ignoring (macro:_==:1)
   warning 6000: unknown variable/constant "{Section_i386w}" detected, ignoring (macro:_==:1)
 (this happens in our gitlab CI jobs, for instance).
 Secondly, most of the emulators in the generated installer don't have
 any mouseover text.
 Make nsis.py generate a second output file which has the necessary
 MUI_DESCRIPTION_TEXT lines for each Section it creates, so we can
 include that at the right point in qemu.nsi to set the mouse-over
 text.

-[PULL 03/21] target/arm: Fix handling of LPAE block descriptors
+[PULL 04/14] target/arm: Don't allow RES0 CNTHCTL_EL2 bits to be written
-LPAE descriptors come in three forms:
+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.
- * table descriptors, giving the address of the next level page table
+In particular, bits [19:18] are only present with FEAT_RME,
- * page descriptors, which occur only at level 3 and describe the
+and bits [17:12] will only be present with FEAT_ECV.
    mapping of one page (which might be 4K, 16K or 64K)
  * block descriptors, which occur at higher page table levels, and
    describe the mapping of huge pages
-QEMU's page-table-walk code treats block and page entries
-identically, simply ORing in a number of bits from the input virtual
-address that depends on the level of the page table that we stopped
-at; we depend on the previous masking of descaddr with descaddrmask
-to have already cleared out the low bits of the descriptor word.
-This is not quite right: the address field in a block descriptor is
-smaller, and so there are bits which are valid address bits in a page
-descriptor or a table descriptor but which are not supposed to be
-part of the address in a block descriptor, and descaddrmask does not
-clear them.  We previously mostly got away with this because those
-descriptor bits are RES0; however with FEAT_BBM (part of Armv8.4)
-block descriptor bit 16 is defined to be the nT bit.  No emulated
-QEMU CPU has FEAT_BBM yet, but if the host CPU has it then we might
-see it when using KVM or hvf.
-Explicitly zero out all the descaddr bits we're about to OR vaddr
-bits into.

-[PULL 16/21] hw/arm/xlnx-zynqmp: Connect the ZynqMP CRF
+[PULL 05/14] target/arm: Implement new FEAT_ECV trap bits
-From: "Edgar E. Iglesias" <edgar.iglesias@xilinx.com>
+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.
-Connect the ZynqMP CRF - Clock Reset FPD device.
+In this commit we implement the trap handling and permit the new
 CNTHCTL_EL2 bits to be written.

+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

-[PULL 14/21] target/arm: Make rvbar settable after realize
+[PULL 07/14] target/arm: Implement FEAT_ECV CNTPOFF_EL2 handling
-From: "Edgar E. Iglesias" <edgar.iglesias@xilinx.com>
+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.
-Make the rvbar property settable after realize. This is done
+Implement the handling for this register, which includes control/trap
-in preparation to model the ZynqMP's runtime configurable rvbar.
+bits in SCR_EL3 and CNTHCTL_EL2.

 about loads from the vector table.  Add logging where we load vector
 table entries.  This is particularly helpful for cases where the user
 has accidentally not put a vector table in their image at all, which
 can result in confusing guest crashes at startup.
 Here's an example of the new logging for a case where
 the vector table contains garbage:
 Loaded reset SP 0x0 PC 0x0 from vector table
 Loaded reset SP 0xd008f8df PC 0xf000bf00 from vector table
 Taking exception 3 [Prefetch Abort] on CPU 0
 ...with CFSR.IACCVIOL
 ...BusFault with BFSR.STKERR
 ...taking pending nonsecure exception 3
 ...loading from element 3 of non-secure vector table at 0xc
 ...loaded new PC 0x20000558
 ----------------
 IN:
 x20000558:  08000079  stmdaeq  r0, {r0, r3, r4, r5, r6}
 (The double reset logging is the result of our long-standing
 "CPUs all get reset twice" weirdness; it looks a bit ugly
 but it'll go away if we ever fix that :-))

-[PULL 15/21] hw/misc: Add a model of the Xilinx ZynqMP CRF
+[PULL 09/14] hw/gpio: Implement STM32L4x5 GPIO
-From: "Edgar E. Iglesias" <edgar.iglesias@xilinx.com>
+From: Inès Varhol <ines.varhol@telecom-paris.fr>
-Add a model of the Xilinx ZynqMP CRF. At the moment this
+Features supported :
-is mostly a stub model.
+- 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
-Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org>
+Difference with the real GPIOs :
-Reviewed-by: Peter Maydell <peter.maydell@linaro.org>
+- Alternate Function and Analog mode aren't implemented :
-Signed-off-by: Edgar E. Iglesias <edgar.iglesias@xilinx.com>
+    pins in AF/Analog behave like pins in input mode
-Message-id: 20220316164645.2303510-4-edgar.iglesias@gmail.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 02/21] target/arm: Fix pauth_check_trap vs SEL2
+[PULL 11/14] tests/qtest: Add STM32L4x5 GPIO QTest testcase
-From: Richard Henderson <richard.henderson@linaro.org>
+From: Inès Varhol <ines.varhol@telecom-paris.fr>
-When arm_is_el2_enabled was introduced, we missed
+The testcase contains :
-updating pauth_check_trap.
+- `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.

-[PULL 01/21] target/arm: Fix sve2 ldnt1 and stnt1
+[PULL 12/14] target/arm: Fix 32-bit SMOPA
 From: Richard Henderson <richard.henderson@linaro.org>
-For both ldnt1 and stnt1, the meaning of the Rn and Rm are different
+While the 8-bit input elements are sequential in the input vector,
-from ld1 and st1: the vector and integer registers are reversed, and
+the 32-bit output elements are not sequential in the output matrix.
-the integer register 31 refers to XZR instead of SP.
+Do not attempt to compute 2 32-bit outputs at the same time.
-Secondly, the 64-bit version of ldnt1 was being interpreted as
+Cc: qemu-stable@nongnu.org
--bit unpacked unscaled offset instead of 64-bit unscaled offset,
+Fixes: 23a5e3859f5 ("target/arm: Implement SME integer outer product")
-which discarded the upper 32 bits of the address coming from

 the vector argument.
 Thirdly, validate that the memory element size is in range for the
 vector element size for ldnt1.  For ld1, we do this via independent
 decode patterns, but for ldnt1 we need to do it manually.

-[PULL 04/21] hw/dma/xlnx_csu_dma: Set TYPE_XLNX_CSU_DMA class_size
+Deleted patch
-In commit 00f05c02f9e7342f we gave the TYPE_XLNX_CSU_DMA object its
-own class struct, but forgot to update the TypeInfo::class_size
-accordingly.  This meant that not enough memory was allocated for the
-class struct, and the initialization of xcdc->read in the class init
-function wrote off the end of the memory. Add the missing line.
-Found by running 'check-qtest-aarch64' with a clang
-address-sanitizer build, which complains:

-[PULL 17/21] hw/misc: Add a model of the Xilinx ZynqMP APU Control
+[PULL 14/14] target/arm: Move v7m-related code from cpu32.c into a separate file
-From: "Edgar E. Iglesias" <edgar.iglesias@xilinx.com>
+From: Thomas Huth <thuth@redhat.com>
-Add a model of the Xilinx ZynqMP APU Control.
+Move the code to a separate file so that we do not have to compile
 it anymore if CONFIG_ARM_V7M is not set.

Mostly straightforward bugfixes. The new Xilinx devices are
arguably 'new feature', but they're fixing a regression where
our changes to PSCI in commit 3f37979bf mean that EL3 guest
code now needs to talk to a proper emulated power-controller
device to turn on secondary CPUs; and it's not yet rc1 and
they only affect the Xilinx board, so it seems OK to me.

thanks

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

For both ldnt1 and stnt1, the meaning of the Rn and Rm are different
from ld1 and st1: the vector and integer registers are reversed, and
the integer register 31 refers to XZR instead of SP.

Secondly, the 64-bit version of ldnt1 was being interpreted as
32-bit unpacked unscaled offset instead of 64-bit unscaled offset,
which discarded the upper 32 bits of the address coming from
the vector argument.

Thirdly, validate that the memory element size is in range for the
vector element size for ldnt1.  For ld1, we do this via independent
decode patterns, but for ldnt1 we need to do it manually.

2.25.1

LPAE descriptors come in three forms:

* table descriptors, giving the address of the next level page table
 * page descriptors, which occur only at level 3 and describe the
   mapping of one page (which might be 4K, 16K or 64K)
 * block descriptors, which occur at higher page table levels, and
   describe the mapping of huge pages

QEMU's page-table-walk code treats block and page entries
identically, simply ORing in a number of bits from the input virtual
address that depends on the level of the page table that we stopped
at; we depend on the previous masking of descaddr with descaddrmask
to have already cleared out the low bits of the descriptor word.

This is not quite right: the address field in a block descriptor is
smaller, and so there are bits which are valid address bits in a page
descriptor or a table descriptor but which are not supposed to be
part of the address in a block descriptor, and descaddrmask does not
clear them.  We previously mostly got away with this because those
descriptor bits are RES0; however with FEAT_BBM (part of Armv8.4)
block descriptor bit 16 is defined to be the nT bit.  No emulated
QEMU CPU has FEAT_BBM yet, but if the host CPU has it then we might
see it when using KVM or hvf.

Explicitly zero out all the descaddr bits we're about to OR vaddr
bits into.

2.25.1

In commit 00f05c02f9e7342f we gave the TYPE_XLNX_CSU_DMA object its
own class struct, but forgot to update the TypeInfo::class_size
accordingly.  This meant that not enough memory was allocated for the
class struct, and the initialization of xcdc->read in the class init
function wrote off the end of the memory. Add the missing line.

Found by running 'check-qtest-aarch64' with a clang
address-sanitizer build, which complains:

Use g_autofree so we free it rather than leaking it.

in an essentially random order (it's whatever glob.glob() returns
them to, which is filesystem-implementation-dependent). Add a
call to sorted() so they appear in alphabetical order.

2.25.1

We use the nsis.py script to write out an installer script Section
for each emulator executable, so the exact set of Sections depends on
which executables were built.  However the part of qemu.nsi which
specifies mouse-over descriptions for each Section still has a
hard-coded and very outdated list (with just i386 and alpha).  This
causes two problems.  Firstly, if you build the installer for a
configuration where you didn't build the i386 binaries you get
warnings like this:
  warning 6000: unknown variable/constant "{Section_i386}" detected, ignoring (macro:_==:1)
  warning 6000: unknown variable/constant "{Section_i386w}" detected, ignoring (macro:_==:1)
(this happens in our gitlab CI jobs, for instance).
Secondly, most of the emulators in the generated installer don't have
any mouseover text.

Make nsis.py generate a second output file which has the necessary
MUI_DESCRIPTION_TEXT lines for each Section it creates, so we can
include that at the right point in qemu.nsi to set the mouse-over
text.

CONFIG_ARM_GIC_TCG actually guards the compilation of TCG GICv3
specific files. So let's rename it into CONFIG_ARM_GICV3_TCG

From: Eric Auger <eric.auger@redhat.com>

In TCG mode, if gic-version=max we always select GICv3 even if
CONFIG_ARM_GICV3_TCG is unset. We shall rather select GICv2.
This also brings the benefit of fixing qos tests errors for tests
using gic-version=max with CONFIG_ARM_GICV3_TCG unset.

Currently the CPU_LOG_INT logging misses some useful information
about loads from the vector table.  Add logging where we load vector
table entries.  This is particularly helpful for cases where the user
has accidentally not put a vector table in their image at all, which
can result in confusing guest crashes at startup.

Here's an example of the new logging for a case where
the vector table contains garbage:

Loaded reset SP 0x0 PC 0x0 from vector table
Loaded reset SP 0xd008f8df PC 0xf000bf00 from vector table
Taking exception 3 [Prefetch Abort] on CPU 0
...with CFSR.IACCVIOL
...BusFault with BFSR.STKERR
...taking pending nonsecure exception 3
...loading from element 3 of non-secure vector table at 0xc
...loaded new PC 0x20000558
----------------
IN:
0x20000558:  08000079  stmdaeq  r0, {r0, r3, r4, r5, r6}

(The double reset logging is the result of our long-standing
"CPUs all get reset twice" weirdness; it looks a bit ugly
but it'll go away if we ever fix that :-))

For M-profile, the fault address is not always exposed to the guest
in a fault register (for instance the BFAR bus fault address register
is only updated for bus faults on data accesses, not instruction
accesses).  Currently we log the address only if we're putting it
into a particular guest-visible register.  Since we always have it,
log it generically, to make logs of i-side faults a bit clearer.

2.25.1

From: Andrew Deason <adeason@sinenomine.net>

On older Solaris releases (before Solaris 11), we didn't get a
prototype for madvise, and so util/osdep.c provides its own prototype.
Some time between the public Solaris 11.4 release and Solaris 11.4.42
CBE, we started getting an madvise prototype that looks like this:

extern int madvise(void *, size_t, int);

which conflicts with the prototype in util/osdeps.c. Instead of always
declaring this prototype, check if we're missing the madvise()
prototype, and only declare it ourselves if the prototype is missing.
Move the prototype to include/qemu/osdep.h, the normal place to handle
platform-specific header quirks.

The 'missing_madvise_proto' meson check contains an obviously wrong
prototype for madvise. So if that code compiles and links, we must be
missing the actual prototype for madvise.

On Solaris, 'sun' is #define'd to 1, which causes errors if a variable
is named 'sun'. Slightly change the name of the var for the Slot User
Number so we can build on Solaris.

From: Andrew Deason <adeason@sinenomine.net>

The include for statvfs.h has not been needed since all statvfs calls
were removed in commit 4a1418e07bdc ("Unbreak large mem support by
removing kqemu").

The comment mentioning CONFIG_BSD hasn't made sense since an include
for config-host.h was removed in commit aafd75841001 ("util: Clean up
includes").

Remove this cruft.

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.

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,

2.34.1

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.

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