New patch
1
The raven_io_ops MemoryRegionOps is the only one in the source tree
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).
1
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.

New patch

1
Armv8.1+ CPUs have the Virtual Host Extension (VHE) which adds a
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.

It doesn't make sense to read the value of MDCR_EL2 on a non-A-profile

An access fault is raised when the Access Flag is not set in the

We support two different encodings for the AArch32 IMPDEF
2
CBAR register -- older cores like the Cortex A9, A7, A15
3
have this at 4, c15, c0, 0; newer cores like the
4
Cortex A35, A53, A57 and A72 have it at 1 c15 c0 0.

The shift of the BaseADDR field depends on the translation
6
When we implemented this we picked which encoding to
4
granule in use.
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

The Cortex-R52 implements the Configuration Base Address Register
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

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.
2
6
3
handle_simd_shift_fpint_conv() was accidentally freeing the TCG
7
However, for the case of accessing SPSR_hyp from hyp mode, it turns
4
temporary tcg_fpstatus too early, before the last use of it. Move
8
out that real hardware permits this, with the same effect as if the
5
the free down to where it belongs.
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.

For convenience of being able to run guest code, permit
19
this UNPREDICTABLE access instead of UNDEFing it.

The MPS SCC device has a lot of different flavours for the various

different MPS FPGA images, which look mostly similar but have
3
differences in how particular registers are handled. Currently we
4
deal with this with a lot of open-coded checks on scc_partno(), but

as we add more board types this is getting a bit hard to read.

New patch
1
1
The MPS2 SCC device is broadly the same for all FPGA images, but has
2
minor differences in the behaviour of the CFG registers depending on
3
the image. In many cases we don't really care about the functionality
4
controlled by these registers and a reads-as-written or similar
5
behaviour is sufficient for the moment.
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.

This commit adds the basic skeleton of the board model, and the
9
code to create all the RAM and ROM. We assume that we're probably
10
going to want to add more images in future, so use the same
11
base class/subclass setup that mps2-tz.c uses, even though at
12
the moment there's only a single subclass.
13
14
Following commits will add the CPUs and the peripherals.

This introduces the DS bit to TCR_ELx, which is RES0 unless the
10
diff --git a/hw/arm/mps3r.c b/hw/arm/mps3r.c

page size is enabled and supports LPA2, resulting in the effective
9
value of DS for a given table walk. The DS bit changes the format
10
of the page table descriptor slightly, moving the PS field out to
11
TCR so that all pages have the same sharability and repurposing
12
those bits of the page table descriptor for the highest bits of
13
the output address.

Do not yet enable FEAT_LPA2; we need extra plumbing to avoid
16
tickling an old kernel bug.

Some of the Cocoa UI methods which call updateUIInfo are invoked as

little cross-thread dance described in the comment just above

call_qemu_main(). This meant they were calling back into the QEMU UI

layer before we'd actually finished initializing our display and

registered the DisplayChangeListener, which isn't really valid. Once
17
updateUIInfo takes the iothread lock, we no longer get away with
18
this, because during this startup phase the iothread lock is held by

the QEMU main-loop thread which is waiting for us to finish our
20
display initialization. So we must suppress updateUIInfo until
21
applicationDidFinishLaunching allows the QEMU main-loop thread to

continue.
