Commit dfc388797cc4 ("hw/arm: xlnx: Set all boards' GEM 'phy-addr'

Similarly to commits dadbb58f59..5ae79fe825 for other ARM boards,
4

4
connect FIQ output of the GIC CPU interfaces to the CPU.
5
to 23. When trying to boot xilinx-zynq-a9 with zynq-zc702.dtb or
6
zynq-zc706.dtb, this results in the following error message when
7
trying to use the Ethernet interface.

8
Reviewed-by: Peter Maydell <peter.maydell@linaro.org>
12
documentation for the ZC702 and ZC706 evaluation boards suggest that the
13
PHY address is 7, not 23. Other boards use PHY address 0, 1, 3, or 7.
14
I was unable to find a documentation or a devicetree file suggesting
15
or using PHY address 23. The Ethernet interface starts working with
16
zynq-zc702.dtb and zynq-zc706.dtb when setting the PHY address to 7,
17
so let's use it.

The API does not generate an error for setting ASYNC | SYNC; that merely
4
constrains the selection vs the per-cpu default. For qemu linux-user,
5
choose SYNC as the default.

When we added SVE_MTEDESC_SHIFT, we effectively limited the
4
maximum size of MTEDESC. Adjust SIZEM1 to consume the remaining
5
bits (32 - 10 - 5 - 12 == 5). Assert that the data to be stored
6
fits within the field (expecting 8 * 4 - 1 == 31, exact fit).

fail to clean_data_tbi or populate mtedesc.

Switch translate-neon.c.inc from being #included into translate.c
1
The raven_io_ops MemoryRegionOps is the only one in the source tree
2
to being its own compilation unit.
2
which sets .valid.unaligned to indicate that it should support
3
unaligned accesses and which does not also set .impl.unaligned to
4
indicate that its read and write functions can do the unaligned
5
handling themselves. This is a problem, because at the moment the
6
core memory system does not implement the support for handling
7
unaligned accesses by doing a series of aligned accesses and
8
combining them (system/memory.c:access_with_adjusted_size() has a
9
TODO comment noting this).
3
10
11
Fortunately raven_io_read() and raven_io_write() will correctly deal
12
with the case of being passed an unaligned address, so we can fix the
13
missing unaligned access support by setting .impl.unaligned in the
14
MemoryRegionOps struct.

Make bswap.h handle being included outside an 'extern "C"' block:
1
We deliberately don't include qtests_npcm7xx in qtests_aarch64,

all system headers are included first, then all declarations are

because we already get the coverage of those tests via qtests_arm,
3
put inside an 'extern "C"' block.

1
The MPS2 SCC device doesn't have any documentation of its properties;
1
Armv8.1+ CPUs have the Virtual Host Extension (VHE) which adds a
2
add a "QEMU interface" format comment describing them.
2
non-secure EL2 virtual timer. We implemented the timer itself in the
3
CPU model, but never wired up its IRQ line to the GIC.
4
5
Wire up the IRQ line (this is always safe whether the CPU has the
6
interrupt or not, since it always creates the outbound IRQ line).
7
Report it to the guest via dtb and ACPI if the CPU has the feature.
8
9
The DTB binding is documented in the kernel's
10
Documentation/devicetree/bindings/timer/arm\,arch_timer.yaml
11
and the ACPI table entries are documented in the ACPI specification
12
version 6.3 or later.
13
14
Because the IRQ line ACPI binding is new in 6.3, we need to bump the
15
FADT table rev to show that we might be using 6.3 features.
16
17
Note that exposing this IRQ in the DTB will trigger a bug in EDK2
18
versions prior to edk2-stable202311, for users who use the virt board
19
with 'virtualization=on' to enable EL2 emulation and are booting an
20
EDK2 guest BIOS, if that EDK2 has assertions enabled. The effect is
21
that EDK2 will assert on bootup:
22
23
ASSERT [ArmTimerDxe] /home/kraxel/projects/qemu/roms/edk2/ArmVirtPkg/Library/ArmVirtTimerFdtClientLib/ArmVirtTimerFdtClientLib.c(72): PropSize == 36 || PropSize == 48
24
25
If you see that assertion you should do one of:
26
* update your EDK2 binaries to edk2-stable202311 or newer
27
* use the 'virt-8.2' versioned machine type
28
* not use 'virtualization=on'
29
30
(The versions shipped with QEMU itself have the fix.)

New patch
1
The patchset adding the GMAC ethernet to this SoC crossed in the
2
mail with the patchset cleaning up the NIC handling. When we
3
create the GMAC modules we must call qemu_configure_nic_device()
4
so that the user has the opportunity to use the -nic commandline
5
option to create a network backend and connect it to the GMACs.
1
6
7
Add the missing call.

New patch
1
Currently QEMU will warn if there is a NIC on the board that
2
is not connected to a backend. By default the '-nic user' will
3
get used for all NICs, but if you manually connect a specific
4
NIC to a specific backend, then the other NICs on the board
5
have no backend and will be warned about:
1
6
7
qemu-system-arm: warning: nic npcm7xx-emc.1 has no peer
8
qemu-system-arm: warning: nic npcm-gmac.0 has no peer
9
qemu-system-arm: warning: nic npcm-gmac.1 has no peer
10
11
So suppress those warnings by manually connecting every NIC
12
on the board to some backend.

Make the WFI helper function return immediately in the usermode
10
We might call pmu_counter_enabled() on an M-profile CPU (for example
16
emulator. This turns WFI into a NOP, which is OK because:
11
from the migration pre/post hooks in machine.c); this should always
17
* architecturally "WFI is a NOP" is a permitted implementation
12
return false because these CPUs don't set ARM_FEATURE_PMU.
18
* aarch64 Linux kernels use the SCTLR_EL1.nTWI bit to trap
19
userspace WFI and NOP it (though aarch32 kernels currently
20
just let WFI do whatever it would do)
21
13
22
We could in theory make the translate.c code special case user-mode
14
Avoid the assertion by not calling arm_mdcr_el2_eff() before we
23
emulation and NOP the insn entirely rather than making the helper
15
have done the early return for "PMU not present".
24
do nothing, but because no real world code will be trying to
25
execute WFI we don't care about efficiency and the helper provides
26
a single place where we can make the change rather than having
27
to touch multiple places in translate.c and translate-a64.c.

This fixes an assertion failure if you try to do a loadvm or

From: Nabih Estefan <nabihestefan@google.com>
2
translate-a64.c and translate.c; make the translate.c function global
3
and drop the translate-a64.c version. To do this we need to also
4
share gen_exception_insn(), which currently exists in two slightly
5
different versions for A32 and A64: merge those into a single
6
function that can work for both.

8
This will be useful for splitting up translate.c, which will require
3
Fix the nocm_gmac-test.c file to run on a nuvoton 7xx machine instead
9
unallocated_encoding() to no longer be file-local. It's also
4
of 8xx. Also fix comments referencing this and values expecting 8xx.
10
hopefully less confusing to have only one version of the function
11
rather than two.

From: Luc Michel <luc.michel@amd.com>

3
An access fault is raised when the Access Flag is not set in the
4
looked-up PTE and the AFFD field is not set in the corresponding context
5
descriptor. This was already implemented for stage 2. Implement it for
6
stage 1 as well.

6
When we implemented this we picked which encoding to
7
use based on whether the CPU set ARM_FEATURE_AARCH64.
8
However this isn't right for three cases:
9
* the qemu-system-arm 'max' CPU, which is supposed to be
10
a variant on a Cortex-A57; it ought to use the same
11
encoding the A57 does and which the AArch64 'max'
12
exposes to AArch32 guest code
13
* the Cortex-R52, which is AArch32-only but has the CBAR
14
at the newer encoding (and where we incorrectly are
15
not yet setting ARM_FEATURE_CBAR_RO anyway)
16
* any possible future support for other v8 AArch32
17
only CPUs, or for supporting "boot the CPU into
18
AArch32 mode" on our existing cores like the A57 etc

21
the CPU implements the ARM_FEATURE_V8 flag instead.
22
23
This changes the behaviour only for the qemu-system-arm
24
'-cpu max'. We don't expect anybody to be relying on the
25
old behaviour because:
26
* it's not what the real hardware Cortex-A57 does
27
(and that's what our ID register claims we are)
28
* we don't implement the memory-mapped GICv3 support
29
which is the only thing that exists at the peripheral
30
base address pointed to by the register

Move the NeonGenThreeOpEnvFn typedef to translate.h together
1
The Cortex-R52 implements the Configuration Base Address Register
2
with the other similar typedefs.
2
(CBAR), as a read-only register. Add ARM_FEATURE_CBAR_RO to this CPU
3
type, so that our implementation provides the register and the
4
associated qdev property.

Both os-win32.h and os-posix.h include system header files. Instead
1
Add the Cortex-R52 IMPDEF sysregs, by defining them here and
2
of having osdep.h include them inside its 'extern "C"' block, make
2
also by enabling the AUXCR feature which defines the ACTLR
3
these headers handle that themselves, so that we don't include the
3
and HACTLR registers. As is our usual practice, we make these
4
system headers inside 'extern "C"'.
4
simple reads-as-zero stubs for now.
5
6
This doesn't fix any current problems, but it's conceptually the
7
right way to handle system headers.

The VFPGenFixPointFn typedef is unused; delete it.
1
Architecturally, the AArch32 MSR/MRS to/from banked register
2
instructions are UNPREDICTABLE for attempts to access a banked
3
register that the guest could access in a more direct way (e.g.
4
using this insn to access r8_fiq when already in FIQ mode). QEMU has
5
chosen to UNDEF on all of these.
6
7
However, for the case of accessing SPSR_hyp from hyp mode, it turns
8
out that real hardware permits this, with the same effect as if the
9
guest had directly written to SPSR. Further, there is some
10
guest code out there that assumes it can do this, because it
11
happens to work on hardware: an example Cortex-R52 startup code
12
fragment uses this, and it got copied into various other places,
13
including Zephyr. Zephyr was fixed to not use this:
14
https://github.com/zephyrproject-rtos/zephyr/issues/47330
15
but other examples are still out there, like the selftest
16
binary for the MPS3-AN536.
17
18
For convenience of being able to run guest code, permit
19
this UNPREDICTABLE access instead of UNDEFing it.

On some boards, SCC config register CFG0 bit 0 controls whether

The MPS2 SCC device is broadly the same for all FPGA images, but has

parts of the board memory map are remapped. Support this with:
2
minor differences in the behaviour of the CFG registers depending on
3
* a device property scc-cfg0 so the board can specify the
3
the image. In many cases we don't really care about the functionality
4
initial value of the CFG0 register
4
controlled by these registers and a reads-as-written or similar
5
* an outbound GPIO line which tracks bit 0 and which the board
5
behaviour is sufficient for the moment.
6
can wire up to provide the remapping
6
7
For the AN536 the required behaviour is:
8
9
* A_CFG0 has CPU reset and halt bits
10
- implement as reads-as-written for the moment
11
* A_CFG1 has flash or ATCM address 0 remap handling
12
- QEMU doesn't model this; implement as reads-as-written
13
* A_CFG2 has QSPI select (like AN524)
14
- implemented (no behaviour, as with AN524)
15
* A_CFG3 is MCC_MSB_ADDR "additional MCC addressing bits"
16
- QEMU doesn't care about these, so use the existing
17
RAZ behaviour for convenience
18
* A_CFG4 is board rev (like all other images)
19
- no change needed
20
* A_CFG5 is ACLK frq in hz (like AN524)
21
- implemented as reads-as-written, as for other boards
22
* A_CFG6 is core 0 vector table base address
23
- implemented as reads-as-written for the moment
24
* A_CFG7 is core 1 vector table base address
25
- implemented as reads-as-written for the moment
26
27
Make the changes necessary for this; leave TODO comments where
28
appropriate to indicate where we might want to come back and
29
implement things like CPU reset.
30
31
The other aspects of the device specific to this FPGA image (like the
32
values of the board ID and similar registers) will be set via the
33
device's qdev properties.

The trans_* functions here are pure code motion with no changes.

It's therefore more convenient for us to model it as a completely

separate C file.

This commit adds the basic skeleton of the board model, and the

code to create all the RAM and ROM. We assume that we're probably

going to want to add more images in future, so use the same

base class/subclass setup that mps2-tz.c uses, even though at

the moment there's only a single subclass.

Following commits will add the CPUs and the peripherals.

per-CPU peripheral part of the address map, whose interrupts are

connected as per-CPU interrupt lines. Then there are 4 UARTs in the

Connect and wire them all up; this involves some OR gates where

The AN524 FPGA image supports two memory maps, which differ in where

Add documentation for the mps3-an536 board type.
2
the QSPI and BRAM are. In the default map, the BRAM is at
3
0x0000_0000, and the QSPI at 0x2800_0000. In the second map, they
4
are the other way around.
5
6
In hardware, the initial mapping can be selected by the user by
7
writing either "REMAP: BRAM" (the default) or "REMAP: QSPI" in the
8
board configuration file. The board config file is acted on by the
9
"Motherboard Configuration Controller", which is an entirely separate
10
microcontroller on the dev board but outside the FPGA.
11
12
The guest can also dynamically change the mapping via the SCC
13
CFG_REG0 register.
14
15
Implement this functionality for QEMU, using a machine property
16
"remap" with valid values "BRAM" and "QSPI" to allow the user to set
17
the initial mapping, in the same way they can on the FPGA, and
18
wiring up the bit from the SCC register to also switch the mapping.
