icv_eoir_write() and icv_dir_write() ignore invalid virtual IRQ numbers
3
Similarly to commits dadbb58f59..5ae79fe825 for other ARM boards,
4
(like LPIs). The issue is that these functions check against the number
4
connect FIQ output of the GIC CPU interfaces to the CPU.
5
of implemented IRQs (QEMU's default is num_irq=288) which can be lower
6
than the maximum virtual IRQ number (1020 - 1). The consequence is that
7
if a hypervisor creates an LR for an IRQ between 288 and 1020, then the
8
guest is unable to deactivate the resulting IRQ. Note that other
9
functions that deal with large IRQ numbers, like icv_iar_read, check
10
against 1020 and not against num_irq.
11

12
Fix the checks by using GICV3_MAXIRQ (1020) instead of the number of

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.

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).

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.

Add a comment documenting the "QEMU interface" of this device:
1
Suppress the deprecation warning when we're running under qtest,
2
which MMIO regions, IRQ lines, GPIO lines, etc it exposes.
2
to avoid "make check" including warning messages in its output.

For the virt board we have two PL061 devices -- one for NonSecure which

The DTB binding is documented in the kernel's
10
Reported-by: Maxim Uvarov <maxim.uvarov@linaro.org>
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.

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.

have done the early return for "PMU not present".

17
This fixes an assertion failure if you try to do a loadvm or
18
savevm for an M-profile board.

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

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.

New patch
1
Add the Cortex-R52 IMPDEF sysregs, by defining them here and
2
also by enabling the AUXCR feature which defines the ACTLR
3
and HACTLR registers. As is our usual practice, we make these
4
simple reads-as-zero stubs for now.

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

(scc_partno(s) == 0x524 && scc_partno(s) == 0x547)

which is clearly wrong as it is never true.

This adds the target guide for Netduino 2, Netduino Plus 2 and STM32VLDISCOVERY.

This register is present on all board types except AN524

and AN527; correct the condition.

30
+The STM32F1 series is based on ARM Cortex-M3 core. The following machines are
31
+based on this chip :
32
+
33
+- ``stm32vldiscovery`` STM32VLDISCOVERY board with STM32F100RBT6 microcontroller

+The STM32F2 series is based on ARM Cortex-M3 core. The following machines are
36
+based on this chip :
37
+
38
+- ``netduino2`` Netduino 2 board with STM32F205RFT6 microcontroller
39
+
40
+The STM32F4 series is based on ARM Cortex-M4F core. This series is pin-to-pin
41
+compatible with STM32F2 series. The following machines are based on this chip :
42
+
43
+- ``netduinoplus2`` Netduino Plus 2 board with STM32F405RGT6 microcontroller

Add tracepoints for reads and writes to the PL061 registers. This requires

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

restructuring pl061_read() to only return after the tracepoint, rather
2
different MPS FPGA images, which look mostly similar but have

3
differences in how particular registers are handled. Currently we

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.

Factor out the conditions into some functions which we can
8
give more descriptive names to.

1
The Luminary variant of the PL061 has registers GPIOPUR and GPIOPDR
1
The MPS2 SCC device is broadly the same for all FPGA images, but has
2
which lets the guest configure whether the GPIO lines are pull-up,
2
minor differences in the behaviour of the CFG registers depending on
3
pull-down, or truly floating. Instead of assuming all lines are pulled
3
the image. In many cases we don't really care about the functionality
4
high, honour the PUR and PDR registers.
4
controlled by these registers and a reads-as-written or similar
5
5
behaviour is sufficient for the moment.
6
For the plain PL061, continue to assume that lines have an external
6
7
pull-up resistor, as we did before.
7
For the AN536 the required behaviour is:

The stellaris board actually relies on this behaviour -- the CD line

* A_CFG0 has CPU reset and halt bits
10
of the ssd0323 display device is connected to GPIO output C7, and it
10
- implement as reads-as-written for the moment
11
is only because of a different bug which we're about to fix that we
11
* A_CFG1 has flash or ATCM address 0 remap handling
12
weren't incorrectly driving this line high on reset and putting the
12
- QEMU doesn't model this; implement as reads-as-written
13
ssd0323 into data mode.
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.

The PL061 GPIO does not itself include pullup or pulldown resistors
1
Create the CPUs, the GIC, and the per-CPU RAM block for
2
to set the value of a GPIO line treated as an output when it is
2
the mps3-an536 board.
3
configured as an input (ie when the PL061 itself is not driving it).
4
In real hardware it is up to the board to add suitable pullups or
5
pulldowns. Currently our implementation hardwires this to "outputs
6
pulled high", which is correct for some boards (eg the realview ones:
7
see figure 3-29 in the "RealView Platform Baseboard for ARM926EJ-S
8
User Guide" DUI0224I), but wrong for others.
9
10
In particular, the wiring in the 'virt' board and the gpio-pwr device
11
assumes that wires should be pulled low, because otherwise the
12
pull-to-high will trigger a shutdown or reset action. (The only
13
reason this doesn't happen immediately on startup is due to another
14
bug in the PL061, where we don't assert the GPIOs to the correct
15
value on reset, but will do so as soon as the guest touches a
16
register and pl061_update() gets called.)
17
18
Add properties to the pl061 so the board can configure whether it
19
wants GPIO lines to have pullup, pulldown, or neither.

Currently the pl061_read() and pl061_write() functions handle offsets

Add the GPIO, watchdog, dual-timer and I2C devices to the mps3-an536

using a combination of three if() statements and a switch(). Clean
2
board. These are all simple devices that just need to be created and
3
this up to use just a switch, using case ranges.

wired up.

5
This requires that instead of catching accesses to the luminary-only
6
registers on a stock PL061 via a check on s->rsvd_start we use
7
an "is this luminary?" check in the cases for each luminary-only
8
register.

+ 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
+ create the second CPU with ``-smp 2``; both CPUs will then start
63
+ execution immediately on startup.
64
+
65
+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.)
