I might squeeze in another pullreq before softfreeze, but the
2
queue was already big enough that I wanted to send this lot out now.

From: Jean-Christophe Dubois <jcd@tribudubois.net>
1
2
3
We need a solution to use an Ethernet PHY that is not the first device
4
on the MDIO bus (device 0 on MDIO bus).
5
6
As an example with the i.MX6UL the NXP SOC has 2 Ethernet devices but
7
only one MDIO bus on which the 2 related PHY are connected but at unique
8
addresses.

will be passed by the machine code to the virtio-iommu-pci
10
device (an array of those). The type of the reserved region
11
will match the virtio_iommu_probe_resv_mem subtype value:
12
- VIRTIO_IOMMU_RESV_MEM_T_RESERVED (0)
13
- VIRTIO_IOMMU_RESV_MEM_T_MSI (1)
14
15
on PC/Q35 machine, this will be used to inform the
16
virtio-iommu-pci device it should bypass the MSI region.
17
The reserved region will be: 0xfee00000:0xfeefffff:1.
18
19
On ARM, we can declare the ITS MSI doorbell as an MSI
20
region to prevent MSIs from being mapped on guest side.

When translating an address we need to check if it belongs to
4
a reserved virtual address range. If it does, there are 2 cases:
5
6
- it belongs to a RESERVED region: the guest should neither use
7
this address in a MAP not instruct the end-point to DMA on
8
them. We report an error
9
10
- It belongs to an MSI region: we bypass the translation.

The machine may need to pass reserved regions to the
4
virtio-iommu-pci device (such as the MSI window on x86
5
or the MSI doorbells on ARM).
6
7
So let's add an array of Interval properties.
8
9
Note: if some reserved regions are already set by the
10
machine code - which should be the case in general -,
11
the length of the property array is already set and
12
prevents the end-user from modifying them. For example,
13
attempting to use:
14
15
-device virtio-iommu-pci,\
16
len-reserved-regions=1,reserved-regions[0]=0xfee00000:0xfeefffff:1
17
18
would result in the following error message:
19
20
qemu-system-aarch64: -device virtio-iommu-pci,addr=0xa,
21
len-reserved-regions=1,reserved-regions[0]=0xfee00000:0xfeefffff:1:
22
array size property len-reserved-regions may not be set more than once
23
24
Otherwise, for example, adding two reserved regions is achieved
25
using the following options:
26
27
-device virtio-iommu-pci,addr=0xa,len-reserved-regions=2,\
28
reserved-regions[0]=0xfee00000:0xfeefffff:1,\
29
reserved-regions[1]=0x1000000:100ffff:1

Using the whole 128 MiB flash in non-secure mode is not working because
3
At the moment the virtio-iommu translates MSI transactions.
4
virt_flash_fdt() expects the same address for secure_sysmem and sysmem.
4
This behavior is inherited from ARM SMMU. The virt machine
5
This is not correctly handled by caller because it forwards NULL for
5
code knows where the guest MSI doorbells are so we can easily
6
secure_sysmem in non-secure flash mode.
6
declare those regions as VIRTIO_IOMMU_RESV_MEM_T_MSI. With that
7
setting the guest will not map MSIs through the IOMMU and those
8
transactions will be simply bypassed.
7
9
8
Fixed by using sysmem when secure_sysmem is NULL.
10
Depending on which MSI controller is in use (ITS or GICV2M),
11
we declare either:
12
- the ITS interrupt translation space (ITS_base + 0x10000),
13
containing the GITS_TRANSLATOR or
14
- The GICV2M single frame, containing the MSI_SETSP_NS register.

1
From: Beata Michalska <beata.michalska@linaro.org>
2
3
Injecting external data abort through KVM might trigger
4
an issue on kernels that do not get updated to include the KVM fix.
5
For those and aarch32 guests, the injected abort gets misconfigured
6
to be an implementation defined exception. This leads to the guest
7
repeatedly re-running the faulting instruction.
8
9
Add support for handling that case.

From: Andrew Jones <drjones@redhat.com>

2
3
The flash device is exclusively for the host-controlled firmware, so
4
we should not expose it to the OS. Exposing it risks the OS messing
5
with it, which could break firmware runtime services and surprise the
6
OS when all its changes disappear after reboot.
7
8
As firmware needs the device and uses DT, we leave the device exposed
9
there. It's up to firmware to remove the nodes from DT before sending
10
it on to the OS. However, there's no need to force firmware to remove
11
tables from ACPI (which it doesn't know how to do anyway), so we
12
simply don't add the tables in the first place. But, as we've been
13
adding the tables for quite some time and don't want to change the
14
default hardware exposed to versioned machines, then we only stop
15
exposing the flash device tables for 5.1 and later machine types.

initializing all its fields. This is a real bug:
4
bcm2835_fb_reconfigure() copies the whole of our new BCM2385FBConfig
5
struct into s->config, so any fields we don't initialize will corrupt
6
the state of the device.
2
7
3
When we converted to using feature bits in 602f6e42cfbf we missed out
8
Copy the two fields which we don't want to update (pixo and alpha)
4
the fact (dp && arm_dc_feature(s, ARM_FEATURE_V8)) was supported for
9
from the existing config so we don't accidentally change them.
5
-cpu max configurations. This caused a regression in the GCC test
6
suite. Fix this by setting the appropriate bits in mvfr1.FPHP to
7
report ARMv8-A with FP support (but not ARMv8.2-FP16).

The spitz board has been around a long time, and still has a fair number

In the next commit we will implement the write_with_attrs()

1
For the four Spitz-family machines (akita, borzoi, spitz, terrier)
2
create a proper abstract class SpitzMachineClass which encapsulates
3
the common behaviour, rather than having them all derive directly
4
from TYPE_MACHINE:
5
* instead of each machine class setting mc->init to a wrapper
6
function which calls spitz_common_init() with parameters,
7
put that data in the SpitzMachineClass and make spitz_common_init
8
the SpitzMachineClass machine-init function
9
* move the settings of mc->block_default_type and
10
mc->ignore_memory_transaction_failures into the SpitzMachineClass
11
class init rather than repeating them in each machine's class init
12
13
(The motivation is that we're going to want to keep some state in
14
the SpitzMachineState so we can connect GPIOs between devices created
15
in one sub-function of the machine init to devices created in a
16
different sub-function.)

New patch
1
Keep pointers to the MPU and the SSI devices in SpitzMachineState.
2
We're going to want to make GPIO connections between some of the
3
SSI devices and the SCPs, so we want to keep hold of a pointer to
4
those; putting the MPU into the struct allows us to pass just
5
one thing to spitz_ssp_attach() rather than two.
1
6
7
We have to retain the setting of the global "max1111" variable
8
for the moment as it is used in spitz_adc_temp_on(); later in
9
this series of commits we will be able to remove it.

New patch
1
Currently the Spitz board uses a nasty hack for the GPIO lines
2
that pass "bit5" and "power" information to the LCD controller:
3
the lcdtg realize function sets a global variable to point to
4
the instance it just realized, and then the functions spitz_bl_power()
5
and spitz_bl_bit5() use that to find the device they are changing
6
the internal state of. There is a comment reading:
7
FIXME: Implement GPIO properly and remove this hack.
8
which was added in 2009.

1
The max111x is a proper qdev device; we can use dc->vmsd rather than
2
directly calling vmstate_register().

4
It's possible that this is a migration compat break, but the only
5
boards that use this device are the spitz-family ('akita', 'borzoi',
6
'spitz', 'terrier').

1
Add an ssi_realize_and_unref(), for the benefit of callers
2
who want to be able to create an SSI device, set QOM properties
3
on it, and then do the realize-and-unref afterwards.

The API works on the same principle as the recently added
6
qdev_realize_and_undef(), sysbus_realize_and_undef(), etc.

New patch
1
The max111x ADC device model allows other code to set the level on
2
the 8 ADC inputs using the max111x_set_input() function. Replace
3
this with generic qdev GPIO inputs, which also allow inputs to be set
4
to arbitrary values.
1
5
6
Using GPIO lines will make it easier for board code to wire things
7
up, so that if device A wants to set the ADC input it doesn't need to
8
have a direct pointer to the max111x but can just set that value on
9
its output GPIO, which is then wired up by the board to the
10
appropriate max111x input.

usual modern style for QOM devices:

4
* definition of the device's state struct so that it can
5
be embedded in other structs if desired
6
* documentation of the interface

This allows us to use TYPE_MAX_1111 in the spitz.c code rather
9
than the string "max1111".

1
Currently we have a free-floating set of IRQs and a function
2
spitz_out_switch() which handle some miscellaneous GPIO lines for the
3
spitz board. Encapsulate this behaviour in a simple QOM device.
4
5
At this point we can finally remove the 'max1111' global, because the
6
ADC battery-temperature value is now handled by the misc-gpio device
7
writing the value to its outbound "adc-temp" GPIO, which the board
8
code wires up to the appropriate inbound GPIO line on the max1111.
9
10
This commit also fixes Coverity issue CID 1421913 (which pointed out
11
that the 'outsignals' in spitz_scoop_gpio_setup() were leaked),
12
because it removes the use of the qemu_allocate_irqs() API from this
13
code entirely.

device using zaurus_printf() (which just prints to stderr), use the
3
usual qemu_log_mask(LOG_GUEST_ERROR,...).

spitz.c, we can move the definition of that macro from sharpsl.h

1
The QOM types "spitz-lcdtg" and "corgi-ssp" are missing the
2
usual QOM TYPE and casting macros; provide and use them.
1
3
4
In particular, we can safely use the QOM cast macros instead of
5
FROM_SSI_SLAVE() because in both cases the 'ssidev' field of
6
the instance state struct is the first field in it.

In the M-profile architecture, when we do a vector table fetch and it
1
Deprecate our TileGX target support:
2
fails, we need to report a HardFault. Whether this is a Secure HF or
2
* we have no active maintainer for it
3
a NonSecure HF depends on several things. If AIRCR.BFHFNMINS is 0
3
* it has had essentially no contributions (other than tree-wide cleanups
4
then HF is always Secure, because there is no NonSecure HardFault.
4
and similar) since it was first added
5
Otherwise, the answer depends on whether the 'underlying exception'
5
* the Linux kernel dropped support in 2018, as has glibc
6
(MemManage, BusFault, SecureFault) targets Secure or NonSecure. (In
7
the pseudocode, this is handled in the Vector() function: the final
8
exc.isSecure is calculated by looking at the exc.isSecure from the
9
exception returned from the memory access, not the isSecure input
10
argument.)
11
6
12
We weren't doing this correctly, because we were looking at
7
Note the deprecation in the manual, but don't try to print a warning
13
the target security domain of the exception we were trying to
8
when QEMU runs -- printing unsuppressable messages is more obtrusive
14
load the vector table entry for. This produces errors of two kinds:
9
for linux-user mode than it would be for system-emulation mode, and
15
* a load from the NS vector table which hits the "NS access
10
it doesn't seem worth trying to invent a new suppressible-error
16
to S memory" SecureFault should end up as a Secure HardFault,
11
system for linux-user just for this.
17
but we were raising an NS HardFault
18
* a load from the S vector table which causes a BusFault
19
should raise an NS HardFault if BFHFNMINS == 1 (because
20
in that case all BusFaults are NonSecure), but we were raising
21
a Secure HardFault
22
23
Correct the logic.
24
25
We also fix a comment error where we claimed that we might
26
be escalating MemManage to HardFault, and forgot about SecureFault.
27
(Vector loads can never hit MPU access faults, because they're
28
always aligned and always use the default address map.)
