2.25.1

In commit d5093d961585f02 we added a VMStateDescription to
the TYPE_ARMV7M object, to handle migration of its Clocks.
However a cut-and-paste error meant we used the wrong struct
name in the VMSTATE_CLOCK() macro arguments. The result was
that attempting a 'savevm' might result in an assertion
failure.

The exynos4210_uart_post_load() function assumes that it is passed
the Exynos4210UartState, but it has been attached to the
VMStateDescription for the Exynos4210UartFIFO type.  The result is a
SIGSEGV when attempting to load VM state for any machine type
including this device.

Fix the bug by attaching the post-load function to the VMSD for the
Exynos4210UartState.  This is the logical place for it, because the
actions it does relate to the entire UART state, not just the FIFO.

Thanks to the bug reporter @TrungNguyen1909 for the clear bug
description and the suggested fix.

softmmu/rtc.c defines two public functions: qemu_get_timedate() and
qemu_timedate_diff().  Currently we keep the prototypes for these in
qemu-common.h, but most files don't need them.  Move them to their
own header, a new include/sysemu/rtc.h.

Since the C files using these two functions did not need to include
qemu-common.h for any other reason, we can remove those include lines
when we add the include of the new rtc.h.

The license for the .h file follows that of the softmmu/rtc.c
where both the functions are defined.

From: Francisco Iglesias <francisco.iglesias@xilinx.com>

An option on real hardware when embedding a DMA engine into a peripheral
is to make the peripheral control the engine through a custom DMA control
(hardware) interface between the two. Software drivers in this scenario
configure and trigger DMA operations through the controlling peripheral's
register API (for example, writing a specific bit in a register could
propagate down to a transfer start signal on the DMA control interface).
At the same time the status, results and interrupts for the transfer might
still be intended to be read and caught through the DMA engine's register
API (and signals).

This patch adds a class 'read' method for allowing to start read transfers
from peripherals embedding and controlling the Xilinx CSU DMA engine as in
above scenario.

If you don't know it, it's hard to figure out the difference between
the linux-headers folder and the include/standard-headers folder.
So let's add a short explanation to clarify the difference.

In an SMP system it can be unclear which CPU is taking an exception;
add the CPU index (which is the same value used in the TCG 'Trace
%d:' logging) to the "Taking exception" log line to clarify it.

2.25.1

In our implementation, all ITSes connected to a GIC share a single
AddressSpace, which we keep in the GICv3State::dma_as field and
initialized based on the GIC's 'sysmem' property. The right place
to set it up by calling address_space_init() is therefore in the
GIC's realize method, not the ITS's realize.

This fixes a theoretical bug where QEMU hangs on startup if the board
model creates two ITSes connected to the same GIC -- we would call
address_space_init() twice on the same AddressSpace*, which creates
an infinite loop in the QTAILQ that softmmu/memory.c uses to store
its list of AddressSpaces and causes any subsequent attempt to
iterate through that list to loop forever.  There aren't any board
models like that in the tree at the moment, though.

The ITS specification says that when the guest writes to GITS_CBASER
this causes GITS_CREADR to be cleared.  However it does not have an
equivalent clause for GITS_CWRITER.  (This is because GITS_CREADR is
read-only, but GITS_CWRITER is writable and the guest can initialize
it.) Remove the code that clears GITS_CWRITER on GITS_CBASER writes.

The GICD_CTLR distributor register has enable bits which control
whether the different interrupt groups (Group 0, Non-secure Group 1
and Secure Group 1) are forwarded to the CPU.  We get this right for
traditional interrupts, but forgot to account for it when adding
LPIs.  LPIs are always Group 1 NS and if the EnableGrp1NS bit is not
set we must not forward them to the CPU.

whether registers like GICR_PROPBASER and GICR_PENDBASER are zero.
There is no requirement in the specification for treating zeroes in
these address registers specially -- they contain guest physical
addresses and it is entirely valid (if unusual) for the guest to
choose to put the tables they address at guest physical address zero.
We use these values only to calculate guest addresses, and attempts
by the guest to use a bad address will be handled by the
address_space_* functions which we use to do the loads and stores.

Remove the unnecessary checks.

The GICR_CTLR.CES bit is a read-only bit which is set to 1 to indicate
that the GICR_CTLR.EnableLPIs bit can be written to 0 to disable
LPIs (as opposed to allowing LPIs to be enabled but not subsequently
disabled). Our implementation permits this, so advertise it
by setting CES to 1.

The MemoryRegionOps gicv3_its_translation_ops currently provides only
a .write_with_attrs function, because the only register in this
region is the write-only GITS_TRANSLATER.  However, if you don't
provide a read function and the guest tries reading from this memory
region, QEMU will crash because
memory_region_read_with_attrs_accessor() calls a NULL pointer.

Add a read function which always returns 0, to cover both bogus
attempts to read GITS_TRANSLATER and also reads from the rest of the
region, which is documented to be reserved, RES0.

The ITS has a bank of 8 GITS_BASER<n> registers, which allow the
guest to specify the base address of various data tables.  Each
register has a read-only type field indicating which table it is for
and a read-write field where the guest can write in the base address
(among other things).  We currently allow the guest to write the
writeable fields for all eight registers, even if the type field is 0
indicating "Unimplemented".  This means the guest can provoke QEMU
into asserting by writing an address into one of these unimplemented
base registers, which bypasses the "if (!value) continue" check in
extract_table_params() and lets us hit the assertion that the type
field is one of the permitted table types.

Prevent the assertion by not allowing the guest to write to the
unimplemented base registers. This means their value will remain 0
and extract_table_params() will ignore them.

Currently when we fill in a TableDesc based on the value the guest
has written to the GITS_BASER<n> register, we calculate both:
 * num_entries : the number of entries in the table, constrained
   by the amount of memory the guest has given it
 * num_ids : the number of IDs we support for this table,
   constrained by the implementation choices and the architecture
   (eg DeviceIDs are 16 bits, so num_ids is 1 << 16)

When validating ITS commands, however, we check only num_ids,
thus allowing a broken guest to specify table entries that
index off the end of it. This will only corrupt guest memory,
but the ITS is supposed to reject such commands as invalid.

Instead of calculating both num_entries and num_ids, set
num_entries to the minimum of the two limits, and check that.

Implement the ITS MOVALL command, which takes all the pending
interrupts on a source redistributor and makes the not-pending on
that source redistributor and pending on a destination redistributor.

This is a GICv3 ITS command which we forgot to implement. (It is
not used by Linux guests.)

Implement the ITS MOVI command. This command specifies a (physical) LPI
by DeviceID and EventID and provides a new ICID for it. The ITS must
find the interrupt translation table entry for the LPI, which will
tell it the old ICID. It then moves the pending state of the LPI from
the old redistributor to the new one and updates the ICID field in
the translation table entry.

This is another GICv3 ITS command that we forgot to implement.  Linux
does use this one, but only if the guest powers off one of its CPUs.

The exception caused by an SVC instruction may be taken to AArch32
Hyp mode for two reasons:
 * HCR.TGE indicates that exceptions from EL0 should trap to EL2
 * we were already in Hyp mode

The entrypoint in the vector table to be used differs in these two
cases: for an exception routed to Hyp mode from EL0, we enter at the
common 0x14 "hyp trap" entrypoint.  For SVC from Hyp mode to Hyp
mode, we enter at the 0x08 (svc/hvc trap) entrypoint.
In the v8A Arm ARM pseudocode this is done in AArch32.TakeSVCException.

QEMU incorrectly routed both of these exceptions to the 0x14
entrypoint.  Correct the entrypoint for SVC from Hyp to Hyp by making
use of the existing logic which handles "normal entrypoint for
Hyp-to-Hyp, otherwise 0x14" for traps like UNDEF and data/prefetch
aborts (reproduced here since it's outside the visible context
in the diff for this commit):

if (arm_current_el(env) != 2 && addr < 0x14) {
        addr = 0x14;
    }

This is just a documentation tweak as we already support both.
FEAT_AA32 implies FEAT_AA32EL0. FEAT_AA64 implies FEAT_AA64EL[0123].

This is however useful if you are using emulation.rst as a source of
truth of what QEMU emulates and when cross checking with
Features.json from Arm.

From: Gaurav Sharma <gaurav.sharma_7@nxp.com>

Implemented CPUs, RAM, UARTs and Interrupt Controller
Other peripherals are represented as TYPE_UNIMPLEMENTED_DEVICE
Complete memory map of the SoC is provided.

Set default RAM size to 2GB and default CPU count to 4 to match
the real i.MX8MM EVK hardware configuration.

Documentation is shared with imx8mp-evk to avoid duplication.

From: Gaurav Sharma <gaurav.sharma_7@nxp.com>

Add configurable properties for register reset values that differ
between i.MX 8M variants (Plus, Mini, etc.). This allows the same
device implementation to be shared across multiple SoCs.

Properties added:
- arm-pll-fdiv-ctl0-reset: ARM PLL divider control reset value

Default value is set to match i.MX 8MP reset value (0x000FA031).
This can be overridden in the variant like iMX8MM with its own
reset value.

From: Gaurav Sharma <gaurav.sharma_7@nxp.com>

Add the Analog IP to i.MX8MM SoC. iMX8MM and i.MX8MP uses
the same Analog IP so the analog ip source will be shared.

The ARM PLL divider control register (arm-pll-fdiv-ctl0) has
a different reset value on i.MX8MM (0x000fa030) compared to
i.MX8MP (0x000fa031). So iMX8MM will be overriding this property
with its own reset-value.

From: Gaurav Sharma <gaurav.sharma_7@nxp.com>

Add the Clock Control Module (CCM) device to i.MX8MM SoC.
The CCM implementation is shared with i.MX8MP as the register
layout is identical between the two variants.Hence iMX8MM will
be using the source of iMX8MP CCM.

From: Gaurav Sharma <gaurav.sharma_7@nxp.com>

SNVS contains an RTC which allows Linux to deal correctly with time

From: Gaurav Sharma <gaurav.sharma_7@nxp.com>

It enables emulation of SD/MMC cards through a virtual SDHCI interface
The emulated SDHCI controller allows guest OS to use emulated storage as
a standard block device.
This will allow running the images such as those generated
by Buildroot.

From: Philippe Mathieu-Daudé <philmd@linaro.org>

As mentioned by Richard in [*]:

We don't actually need any specific endianness here, because
  every byte has the same value.  So we could simply drop MO_TE.
  That would produce a store in host-endianness, which will be
  fractionally more efficient on some hosts.

From: Thomas Huth <thuth@redhat.com>

When writing to this register, QEMU currently aborts:

$ echo "readl 0x10000018" | ./qemu-system-arm -audiodev none,id=snd0 \
    -M integratorcp,accel=qtest,audiodev=snd0 -display none -qtest stdio
 [I 0.000000] OPENED
 [R +0.001907] readl 0x10000018
 qemu: hardware error: integratorcm_read: CM_LMBUSCNT
 [...]
 Aborted                    (core dumped)

This is bad, a guest should ideally never be able to kill QEMU like this.

Now, according to the "Intergrator/CP User Guide" from:

https://developer.arm.com/documentation/dui0159/b/porting-integrator-ap-and-im-pd1/registers

"The Integrator/AP CM_LMBUSCNT has been removed."

That means this register does not seem to be implemented on real CP boards
at all, only for older AP boards. Thus it should be fine if we simply
ignore this register in QEMU and handle it like all other unimplemented
registers in the "default" handler of the case statement.

include/hw/arm/primecell.h used to be more expansive, but now the
only thing it defines is the ARM_SYSCTL_GPIO_* constants for the GPIO
lines for the arm-sysctl system-control device used on the Realview,
Versatile and Versatile Express boards.

Replace it with a header file specific to that device.

virt.c and vmapple.c included primecell.h despite not using the
constants it defined; there we can simply drop the include entirely.

2.43.0

If we create a normally-AArch64 CPU and configure it with
aarch64=off, this will by default leave all the AArch64 ID register
values in its ARMISARegisters struct untouched.  That in turn means
that tests of cpu_isar_feature(aa64_something, cpu) will return true.

Until now we have had a design policy that you shouldn't check an
aa64_ feature unless you know that the CPU has AArch64; but this is
quite fragile as it's easy to forget and only causes a problem in the
corner case where AArch64 was turned off.  In particular, when we
extend the ability to disable AArch64 from only KVM to also TCG there
are many more aa64 feature check points which we would otherwise have
to audit for whether they needed to be guarded with a check on
ARM_FEATURE_AARCH64.

Instead, make the CPU realize function zero out all the 64-bit ID
registers if a TCG CPU doesn't have AArch64; this will make aa64_
feature tests generally return false.

We only do this for TCG because only TCG really needs it, and for
KVM it might be confusing to have QEMU's idea of the ID registers
be different from KVM's.

Allow the 'aarch64=off' property, which is currently KVM-only, to
be set for TCG CPUs also.

Note that we don't permit it on the qemu-aarch64 user-mode binary:
this makes no sense as that executable can only handle AArch64
syscalls (and it would also assert at startup since it doesn't
compile in the A32-specific GDB xml files like arm-neon.xml).

Add a basic test of the TCG 'aarch64=off' functionality; this is the
same as our existing arm/test_virt test, but it runs the AArch32
guest kernel on qemu-system-aarch64 with -cpu max,aarch64=off.

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

We introduce a datatype for a tolerance with respect to a given
cpreg migration issue. The tolerance applies to a given cpreg kvm index,
and can be of different types:
a) mismatch in cpreg indexes
- ToleranceNotOnBothEnds (cpreg index is allowed to be only present
  on one end)
- ToleranceOnlySrcTestValue (cpreg index is allowed to be only
  present in source if its value @mask field matches @value)
b) mismatch in cpreg values
- ToleranceDiffInMask (value differences are allowed only within a mask)
- ToleranceFieldLT (incoming field value must be less than a given value)
- ToleranceFieldGT (incoming field value must be greater than a given value)

A QLIST of such tolerances can be populated using a new helper:
arm_register_cpreg_mig_tolerance() and arm_cpu_match_cpreg_mig_tolerance()
allows to check whether a tolerance exists for a given kvm index and its
criterion is matched.

callers for those helpers will be introduced in subsequent patches.

Only registration of migration tolerances related to cpreg index
mismatch is currently allowed.

If there is a mismatch between the cpreg indexes found on both ends,
check whether a tolerance was registered for the given kvmidx. If any,
silence warning/errors.

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

Before linux v6.13 those registers were erroneously unconditionally
exposed and this was fixed by commits:
- 0fcb4eea5345 ("KVM: arm64: Hide TCR2_EL1 from userspace when
                 disabled for guests")
- a68cddbe47ef ("KVM: arm64: Hide S1PIE registers from userspace
                 when disabled for guests")
in v6.13.

This means if we migrate from an old kernel host to a >= 6.13 kernel
host, migration currently fails.

Declare cpreg migration tolerance for those registers.

KVM_REG_ARM_VENDOR_HYP_BMAP_2 pseudo FW register is exposed
from v6.15 onwards. Backward migration from a >= v6.15 to an older
kernel would fail without cpreg migration tolerance definition
for this register. If the register is present on source but not
on destination, its value must be checked to make sure it matches
the reset value, ie. 0, meaning no service is exposed to the guest,
hence the choice of a ToleranceOnlySrcTestValue migration
tolerance.

We want to remove AArch32 DBGDTRTX which was erroneously exposed.
This was attempted by 655659a74a36b ("target/arm: Correct encoding
of Debug Communications Channel registers") but it was discovered
that the removal of this debug register broke forward migration on
TCG. Now we have the cpreg migration tolerance infrastructure, we
can declare one for the DBGDTRTX. This allow to revert the reinstate
patch.

fdt_node_offset_by_compatible(fdt, -1, compat) only finds the first match.
If the blob has more than one node with the same compatible string, extra
nodes will remain active. Remove all the matching nodes, using the same
loop as imx8mp-evk.c does for this purpose.

Implement a basic i.MX6UL LCDIF controller model with MMIO registers,
frame-done interrupt behavior, and framebuffer-backed display updates
for RGB565 and XRGB8888 input formats.

Place the LCDIF device under hw/display and build it via a dedicated
CONFIG_IMX6UL_LCDIF symbol. Model register fields with
registerfields.h helpers and provide migration support via vmstate.

From: Yucai Liu <1486344514@qq.com>

Instantiate LCDIF as a child object of the i.MX6UL SoC in init and
realize it in the SoC realize path before MMIO/IRQ hookup.

Also make FSL_IMX6UL select CONFIG_IMX6UL_LCDIF and map the LCDIF
region with a 16 KiB size to match the SoC memory map.

We have a registerfields interface which we can use for defining
fields alongside helpers to access them. Define the basic syndrome
layout and convert the helpers that take the imm16 data directly.
