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.

Since Linux v3.17, the kernel's Image header includes a field image_size,
1
From: Richard Henderson <richard.henderson@linaro.org>
2
which gives the total size of the kernel including unpopulated data
3
sections such as the BSS). If this is present, then return it from
4
load_aarch64_image() as the true size of the kernel rather than
5
just using the size of the Image file itself. This allows the code
6
which calculates where to put the initrd to avoid putting it in
7
the kernel's BSS area.
8
2
9
This means that we should be able to reliably load kernel images
3
The field is encoded as [0-3], which is convenient for
10
which are larger than 128MB without accidentally putting the
4
indexing our array of function pointers, but the true
11
initrd or dtb in locations that clash with the kernel itself.
5
value is [1-4]. Adjust before calling do_mem_zpa.

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).

We currently put the initrd at the smaller of:

which sets .valid.unaligned to indicate that it should support

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

that. For image formats that can give us an exact kernel size, this

will mean that we definitely avoid overlaying kernel and initrd.

Stop using cpu_F0s in the Neon VCVT fixed-point operations.

We deliberately don't include qtests_npcm7xx in qtests_aarch64,
2
because we already get the coverage of those tests via qtests_arm,
3
and we don't want to use extra CI minutes testing them twice.

2.34.1

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.
1

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.

Remove the now unused TCG globals cpu_F0s, cpu_F0d, cpu_F1s, cpu_F1d.
1
It doesn't make sense to read the value of MDCR_EL2 on a non-A-profile
2
CPU, and in fact if you try to do it we will assert:
2
3
3
cpu_M0 is still used by the iwmmxt code, and cpu_V0 and
4
#6 0x00007ffff4b95e96 in __GI___assert_fail
4
cpu_V1 are used by both iwmmxt and Neon.
5

5
9
10
We might call pmu_counter_enabled() on an M-profile CPU (for example
11
from the migration pre/post hooks in machine.c); this should always
12
return false because these CPUs don't set ARM_FEATURE_PMU.
13
14
Avoid the assertion by not calling arm_mdcr_el2_eff() before we
15
have done the early return for "PMU not present".
16
17
This fixes an assertion failure if you try to do a loadvm or
18
savevm for an M-profile board.

New patch

From: Luc Michel <luc.michel@amd.com>
1
2
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.

In several places cut and paste errors meant we were using the wrong

type for the 'arg' struct in trans_ functions called by the
3
decodetree decoder, because we were using the _sp version of the
4
struct in the _dp function. These were harmless, because the two
5
structs were identical and so decodetree made them typedefs of the
6
same underlying structure (and we'd have had a compile error if they
7
were not harmless), but we should clean them up anyway.

The GICv3 specification says that the GICD_TYPER.SecurityExtn bit
1
From: Philippe Mathieu-Daudé <philmd@linaro.org>
2
is RAZ if GICD_CTLR.DS is 1. We were incorrectly making it RAZ
3
if the security extension is unsupported. "Security extension
4
unsupported" always implies GICD_CTLR.DS == 1, but the guest can
5
also set DS on a GIC which does support the security extension.
6
Fix the condition to correctly check the GICD_CTLR.DS bit.

Stop using cpu_F0s for NEON_2RM_VRECPE_F and NEON_2RM_VRSQRTE_F.
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.
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

also by enabling the AUXCR feature which defines the ACTLR

The AArch32 VMOV (immediate) instruction uses the same VFP encoded
1
Architecturally, the AArch32 MSR/MRS to/from banked register
2
immediate format we already handle in vfp_expand_imm(). Use that
2
instructions are UNPREDICTABLE for attempts to access a banked
3
function rather than hand-decoding it.
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.

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.

only the first 0x20 bytes.

"Subsystem for Embedded" SoC-equivalent that we model in hw/arm/armsse.c.

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
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

base class/subclass setup that mps2-tz.c uses, even though at
12
the moment there's only a single subclass.

Following commits will add the CPUs and the peripherals.

We want to use vfp_expand_imm() in the AArch32 VFP decode;

This board has a lot of UARTs: there is one UART per CPU in the
2
move it from the a64-only header/source file to the
2
per-CPU peripheral part of the address map, whose interrupts are
3
AArch32 one (which is always compiled even for AArch64).
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.
6
7
Connect and wire them all up; this involves some OR gates where
8
multiple overflow interrupts are wired into one GIC input.

The primary motivation here is to be able to optionally
7
create Cortex-M33 CPUs with no FPU, but we provide switches
8
for both VFP and Neon because the two interact:
9
* AArch64 can't have one without the other
10
* Some ID register fields only change if both are disabled

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.)
