Mostly just bug fixes. The important one here is
1
The following changes since commit 5767815218efd3cbfd409505ed824d5f356044ae:
2
hw/intc/arm_gic: Fix interrupt ID in GICD_SGIR register
3
which fixes a buffer overrun that's a security issue if you're running
4
KVM on Arm with kernel-irqchip=off (which hopefully nobody is doing in
5
a security context, because kernel-irqchip=on is the default and the
6
sensible choice for performance).

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,

choose SYNC as the default.

Per the ARM Generic Interrupt Controller Architecture specification

The field is encoded as [0-3], which is convenient for

(document "ARM IHI 0048B.b (ID072613)"), the SGIINTID field is 4 bit,
4
indexing our array of function pointers, but the true

not 10:

value is [1-4]. Adjust before calling do_mem_zpa.

This fixes a security issue when running with KVM on Arm with
27
kernel-irqchip=off. (The default is kernel-irqchip=on, which is
28
unaffected, and which is also the correct choice for performance.)

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).

When the block is disabled, it stay it is 'internal reset logic'

The TBI and TCMA bits are located within mtedesc, not desc.

(internal clocks are gated off). Reading any register returns
5
its reset value. Only update this value if the device is enabled.

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).
2
10
3
The STM32F405 SoC uses an OR gate on its ADC IRQs.
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
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.

7
Add the missing call.

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

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.

New patch
1
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.
1
5
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
19
20
Make the decision of the encoding be based on whether
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

From: Iris Johnson <iris@modwiz.com>
1
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
4
associated qdev property.
2
5
3
When the frontend device has no space for a read the fd is removed
4
from polling to allow time for the guest to read and clear the buffer.
5
Without the call to qemu_chr_fe_accept_input(), the poll will not be
6
broken out of when the guest has cleared the buffer causing significant
7
IO delays that get worse with smaller buffers.

2
also by enabling the AUXCR feature which defines the ACTLR

New patch
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.
1
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.

We currently guard the CFG3 register read with

0x021 A SPI burst contains the 2 LSB in first word and all 32 bits in second word.
7
8
Current logic uses either s->burst_length or 32, whichever smaller,
9
to determine how many bits it should read from the tx fifo each time.
10
For example, for a 48 bit burst length, current logic transfers the
11
first 32 bit from the first word in the tx fifo, followed by a 16
12
bit from the second word in the tx fifo, which is wrong. The correct
13
logic should be: transfer the first 16 bit from the first word in
14
the tx fifo, followed by a 32 bit from the second word in the tx fifo.

The MPS SCC device has a lot of different flavours for the various
2
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
5
as we add more board types this is getting a bit hard to read.

Currently the Exynos 4210 UART code always reports available FIFO space
7
Factor out the conditions into some functions which we can
4
when the backend checks for buffer space. When the FIFO is disabled this
8
give more descriptive names to.
5
is behavior causes the backend chardev code to replace the data before the
6
guest can read it.

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.

1
The AN536 is another FPGA image for the MPS3 development board. Unlike
2
2
the existing FPGA images we already model, this board uses a Cortex-R
3
The Versal SoC instantiates the TYPE_XLNX_ZDMA object in
3
family CPU, and it does not use any equivalent to the M-profile
4
versal_create_admas(). Introduce the XLNX_ZDMA configuration
4
"Subsystem for Embedded" SoC-equivalent that we model in hw/arm/armsse.c.
5
and select it to fix:
5
It's therefore more convenient for us to model it as a completely
6

separate C file.

This board has a lot of UARTs: there is one UART per CPU in the
2
per-CPU peripheral part of the address map, whose interrupts are
3
connected as per-CPU interrupt lines. Then there are 4 UARTs in the
4
normal part of the peripheral space, whose interrupts are shared
5
peripheral interrupts.

Usually the approach is that the device on the other end of the line

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

is going to reset its state anyway, so there's no need to actively
8
multiple overflow interrupts are wired into one GIC input.

current_cpu is NULL because QTest accelerator does not use CPU.
32
33
Fix by skipping the check and returning the first CPU index when
34
QTest accelerator is used, similarly to commit c781a2cc423
35
("hw/i386/vmport: Allow QTest use without crashing").

56

+- AN536 defaults to only creating a single CPU; this is the equivalent
60
+ of the way the real FPGA image usually runs with the second Cortex-R52
61
+ held in halt via the initial SCC CFG_REG0 register setting. You can
62

+Note that for the AN536 the first UART is accessible only by
66
+CPU0, and the second UART is accessible only by CPU1. The
67
+first UART accessible shared between both CPUs is the third
68
+UART. Guest software might therefore be built to use either
69
+the first UART or the third UART; if you don't see any output
70
+from the UART you are looking at, try one of the others.
71
+(Even if the AN536 machine is started with a single CPU and so
72
+no "CPU1-only UART", the UART numbering remains the same,
73
+with the third UART being the first of the shared ones.)
