QEMU coding style uses the glib memory allocation APIs, not

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

the raw libc malloc/free. Switch the allocation and free

calls in elf2dmp to use these functions (dropping the now-unneeded

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.

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

non-secure EL2 virtual timer. We implemented the timer itself in the

As in, PPI0 is INTID16 .. PPI15 is INTID31.

Arm's Base System Architecture specification (BSA) lists the mandated and

Wire up the IRQ line (this is always safe whether the CPU has the

definitions in virt define them by PPI index, complicating cross

The DTB binding is documented in the kernel's

Meanwhile, the PPI(x) macro counterintuitively adds 16 to the input value,

11
converting a PPI index to an INTID.
11
and the ACPI table entries are documented in the ACPI specification
12
12
version 6.3 or later.
13
Resolve this by redefining the BSA-allocated PPIs by their INTIDs,
13
14
and replacing the PPI(x) macro with an INTID_TO_PPI(x) one where required.
14
Because the IRQ line ACPI binding is new in 6.3, we need to bump the

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.

New patch

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:
1
3
4
#6 0x00007ffff4b95e96 in __GI___assert_fail
5
(assertion=0x5555565a8c70 "!arm_feature(env, ARM_FEATURE_M)", file=0x5555565a6e5c "../../target/arm/helper.c", line=12600, function=0x5555565a9560 <__PRETTY_FUNCTION__.0> "arm_security_space_below_el3") at ./assert/assert.c:101
6
#7 0x0000555555ebf412 in arm_security_space_below_el3 (env=0x555557bc8190) at ../../target/arm/helper.c:12600
7
#8 0x0000555555ea6f89 in arm_is_el2_enabled (env=0x555557bc8190) at ../../target/arm/cpu.h:2595
8
#9 0x0000555555ea942f in arm_mdcr_el2_eff (env=0x555557bc8190) at ../../target/arm/internals.h:1512
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.

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.
2
5
3
On an attempt to access CNTPCT_EL0 from EL0 using a guest running on top
6
When we implemented this we picked which encoding to
4
of Xen, a trap from EL2 was observed which is something not reproducible
7
use based on whether the CPU set ARM_FEATURE_AARCH64.
5
on HW (also, Xen does not trap accesses to physical counter).
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

This is because gt_counter_access() checks for an incorrect bit (1

physical counter. Refer ARM ARM DDI 0487J.a, D19.12.2:
10
When HCR_EL2.E2H is 0:
11
- EL1PCTEN, bit [0]: refers to physical counter
12
- EL1PCEN, bit [1]: refers to physical timer registers
13
22
14
Drop entire block "if (hcr & HCR_E2H) {...} else {...}" from EL0 case
23
This changes the behaviour only for the qemu-system-arm
15
and fall through to EL1 case, given that after fixing checking for the
24
'-cpu max'. We don't expect anybody to be relying on the
16
correct bit, the handling is the same.
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

associated qdev property.

This include was originally needed because the semihosting code used
6
the arm_boot_info struct to get the base address of the RAM in system
7
emulation, to use in a (bad) heuristic for the return values for the
8
SYS_HEAPINFO semihosting call. We've since overhauled how we
9
calculate the HEAPINFO values in system emulation, and the code no

longer uses the arm_boot_info struct.

Remove the now-redundant include line, and instead directly include

the cpu-qom.h header that we were previously getting via boot.h.

In smmuv3_init_regs() when we set the various bits in the ID

Architecturally, the AArch32 MSR/MRS to/from banked register
2
registers, we do this almost in order of the fields in the
2
instructions are UNPREDICTABLE for attempts to access a banked
3
registers, but not quite. Move the initialization of
3
register that the guest could access in a more direct way (e.g.
4
SMMU_IDR3.RIL and SMMU_IDR5.OAS into their correct places.
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.

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.

Factor out the conditions into some functions which we can

The SMMUv3.1-XNX feature is mandatory for an SMMUv3.1 if S2P is

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

minor differences in the behaviour of the CFG registers depending on

the recent S2P work. Fortunately, for us the implementation is a

This feature is about interpretation of the stage 2 page table

For the AN536 the required behaviour is:

For QEMU, the permission bits passed to an IOMMU (via MemTxAttrs and

SMMU architecture's terms, our interconnect between the client device

13
and the SMMU doesn't have the ability to convey the INST attribute,
13
* A_CFG2 has QSPI select (like AN524)
14
and we therefore use the default value of "data" for this attribute.
14
- implemented (no behaviour, as with AN524)
15
15
* A_CFG3 is MCC_MSB_ADDR "additional MCC addressing bits"

We also do not support the bits in the Stream Table Entry that can

These two things together mean that for our implementation, it never

Advertise the presence of the feature in SMMU_IDR3.XNX.

Make the changes necessary for this; leave TODO comments where
28
appropriate to indicate where we might want to come back and

implement things like CPU reset.

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

12
that permits correct running at that lower EL. We already do a
13
little of this in arm-powerctl.c (for instance we set SCR_HCE to
14
enable the HVC insn) but we don't do enough of it. This means that
15
in the case where we are emulating EL3 but also providing emulated
16
PSCI the guest will crash when a secondary core tries to use a
17
feature that needs an SCR_EL3 bit to be set, such as MTE or PAuth.

The hw/arm/boot.c code also has to support this "start guest code in

an EL that's lower than the highest emulated EL" case in order to do
21
direct guest kernel booting; it has all the necessary initialization
22
code to set the SCR_EL3 bits. Pull the relevant boot.c code out into
23
a separate function so we can share it between there and
24
arm-powerctl.c.
25
26
This refactoring has a few code changes that look like they
27
might be behaviour changes but aren't:
28
* if info->secure_boot is false and info->secure_board_setup is
29
true, then the old code would start the first CPU in Hyp
30
mode but without changing SCR.NS and NSACR.{CP11,CP10}.
31
This was wrong behaviour because there's no such thing
32
as Secure Hyp mode. The new code will leave the CPU in SVC.
33
(There is no board which sets secure_boot to false and
34
secure_board_setup to true, so this isn't a behaviour
35
change for any of our boards.)
36
* we don't explicitly clear SCR.NS when arm-powerctl.c
37
does a CPU-on to EL3. This was a no-op because CPU reset
38
will reset to NS == 0.
39
40
And some real behaviour changes:
41
* we no longer set HCR_EL2.RW when booting into EL2: the guest
42
can and should do that themselves before dropping into their
43
EL1 code. (arm-powerctl and boot did this differently; I
44
opted to use the logic from arm-powerctl, which only sets
45
HCR_EL2.RW when it's directly starting the guest in EL1,
46
because it's more correct, and I don't expect guests to be
47
accidentally depending on our having set the RW bit for them.)
48
* if we are booting a CPU into AArch32 Secure SVC then we won't
49
set SCR.HCE any more. This affects only the vexpress-a15 and
50
raspi2b machine types. Guests booting in this case will either:
51
- be able to set SCR.HCE themselves as part of moving from
52
Secure SVC into NS Hyp mode
53
- will move from Secure SVC to NS SVC, and won't care about
54
behaviour of the HVC insn
55
- will stay in Secure SVC, and won't care about HVC
56
* on an arm-powerctl CPU-on we will now set the SCR bits for
57
pauth/mte/sve/sme/hcx/fgt features
58
59
The first two of these are very minor and I don't expect guest
60
code to trip over them, so I didn't judge it worth convoluting
61
the code in an attempt to keep exactly the same boot.c behaviour.
62
The third change fixes issue 1899.

55
+ base address via the SCC CFG_REG6 and CFG_REG7 register config,
56
+ and does not provide a mechanism for specifying these values at
57
+ startup, so all guest images must be built to start from TCM
58

59
+- 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

63

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.)
