Target-arm queue for rc2 -- just some minor bugfixes.
1
First arm pullreq for 7.1. The bulk of this is the qemu_split_irq
2
removal.

I have enough stuff in my to-review queue that I expect to do another
5
pullreq early next week, but 31 patches is enough to not hang on to.

New patch
1
It's not possible to provide the guest with the Security extensions
2
(TrustZone) when using KVM or HVF, because the hardware
3
virtualization extensions don't permit running EL3 guest code.
4
However, we weren't checking for this combination, with the result
5
that QEMU would assert if you tried it:
1
6
7
$ qemu-system-aarch64 -enable-kvm -machine virt,secure=on -cpu host -display none
8
Unexpected error in object_property_find_err() at ../../qom/object.c:1304:
9
qemu-system-aarch64: Property 'host-arm-cpu.secure-memory' not found
10
Aborted
11
12
Check for this combination of options and report an error, in the
13
same way we already do for attempts to give a KVM or HVF guest the
14
Virtualization or MTE extensions. Now we will report:
15
16
qemu-system-aarch64: mach-virt: KVM does not support providing Security extensions (TrustZone) to the guest CPU

The Exynos4210 SoC device currently uses a custom device
2
"exynos4210.irq_gate" to model the OR gate that feeds each CPU's IRQ
3
line. We have a standard TYPE_OR_IRQ device for this now, so use
4
that instead.

3
A few configuration register writes need not update the spi bus state, so just
6
(This is a migration compatibility break, but that is OK for this
4
return after the register write.

machine type.)

New patch
1
The exynos4210 SoC mostly creates its child devices as if it were
2
board code. This includes the a9mpcore object. Switch that to a
3
new-style "embedded in the state struct" creation, because in the
4
next commit we're going to want to refer to the object again further
5
down in the exynos4210_realize() function.

New patch
1
The only time we use the int_gic_irq[] array in the Exynos4210Irq
2
struct is in the exynos4210_realize() function: we initialize it with
3
the GPIO inputs of the a9mpcore device, and then a bit later on we
4
connect those to the outputs of the internal combiner. Now that the
5
a9mpcore object is easily accessible as s->a9mpcore we can make the
6
connection directly from one device to the other without going via
7
this array.

New patch
1
The exynos4210 code currently has two very similar arrays of IRQs:
1
2
3
* board_irqs is a field of the Exynos4210Irq struct which is filled
4
in by exynos4210_init_board_irqs() with the appropriate qemu_irqs
5
for each IRQ the board/SoC can assert
6
* irq_table is a set of qemu_irqs pointed to from the
7
Exynos4210State struct. It's allocated in exynos4210_init_irq,
8
and the only behaviour these irqs have is that they pass on the
9
level to the equivalent board_irqs[] irq
10
11
The extra indirection through irq_table is unnecessary, so coalesce
12
these into a single irq_table[] array as a direct field in
13
Exynos4210State which exynos4210_init_board_irqs() fills in.

1
The function exynos4210_init_board_irqs() currently lives in
2
exynos4210_gic.c, but it isn't really part of the exynos4210.gic
3
device -- it is a function that implements (some of) the wiring up of
4
interrupts between the SoC's GIC and combiner components. This means
5
it fits better in exynos4210.c, which is the SoC-level code. Move it
6
there. Similarly, exynos4210_git_irq() is used almost only in the
7
SoC-level code, so move it too.

1
Switch the creation of the external GIC to the new-style "embedded in
2
state struct" approach, so we can easily refer to the object
3
elsewhere during realize.

New patch
1
The only time we use the ext_gic_irq[] array in the Exynos4210Irq
2
struct is during realize of the SoC -- we initialize it with the
3
input IRQs of the external GIC device, and then connect those to
4
outputs of other devices further on in realize (including in the
5
exynos4210_init_board_irqs() function). Now that the ext_gic object
6
is easily accessible as s->ext_gic we can make the connections
7
directly from one device to the other without going via this array.

New patch
1
The function exynos4210_combiner_get_gpioin() currently lives in
2
exynos4210_combiner.c, but it isn't really part of the combiner
3
device itself -- it is a function that implements the wiring up of
4
some interrupt sources to multiple combiner inputs. Move it to live
5
with the other SoC-level code in exynos4210.c, along with a few
6
macros previously defined in exynos4210.h which are now used only
7
in exynos4210.c.

New patch
1
In exynos4210_init_board_irqs(), the loop that handles IRQ lines that
2
are in a range that applies to the internal combiner only creates a
3
splitter for those interrupts which go to both the internal combiner
4
and to the external GIC, but it does nothing at all for the
5
interrupts which don't go to the external GIC, leaving the
6
irq_table[] array element empty for those. (This will result in
7
those interrupts simply being lost, not in a QEMU crash.)
1
8
9
I don't have a reliable datasheet for this SoC, but since we do wire
10
up one interrupt line in this category (the HDMI I2C device on
11
interrupt 16,1), this seems like it must be a bug in the existing
12
QEMU code. Fill in the irq_table[] entries where we're not splitting
13
the IRQ to both the internal combiner and the external GIC with the
14
IRQ line of the internal combiner. (That is, these IRQ lines go to
15
just one device, not multiple.)
16
17
This bug didn't have any visible guest effects because the only
18
implemented device that was affected was the HDMI I2C controller,
19
and we never connect any I2C devices to that bus.

New patch
1
Currently for the interrupts MCT_G0 and MCT_G1 which are
2
the only ones in the input range of the external combiner
3
and which are also wired to the external GIC, we connect
4
them only to the internal combiner and the external GIC.
5
This seems likely to be a bug, as all other interrupts
6
which are in the input range of both combiners are
7
connected to both combiners. (The fact that the code in
8
exynos4210_combiner_get_gpioin() is also trying to wire
9
up these inputs on both combiners also suggests this.)
1
10
11
Wire these interrupts up to both combiners, like the rest.

1
The combiner_grp_to_gic_id[] array includes the EXT_GIC_ID_MCT_G0
2
and EXT_GIC_ID_MCT_G1 multiple times. This means that we will
3
connect multiple IRQs up to the same external GIC input, which
4
is not permitted. We do the same thing in the code in
5
exynos4210_init_board_irqs() because the conditionals selecting
6
an irq_id in the first loop match multiple interrupt IDs.

(1, 5), (12, 5), (35, 5), (51, 5), (53, 5) for EXT_GIC_ID_MCT_G1
12
13
These correspond to the cases for the multi-core timer that we are
14
wiring up to multiple inputs on the combiner in
15
exynos4210_combiner_get_gpioin(). That code already deals with all
16
these interrupt IDs being the same input source, so we don't need to
17
connect the external GIC interrupt for any of them except the first
18
(1, 4) and (1, 5). Remove the array entries and conditionals which
19
were incorrectly causing us to wire up extra lines.
20
21
This bug didn't cause any visible effects, because we only connect
22
up a device to the "primary" ID values (1, 4) and (1, 5), so the
23
extra lines would never be set to a level.

1
At this point, the function exynos4210_init_board_irqs() splits input
2
IRQ lines to connect them to the input combiner, output combiner and
3
external GIC. The function exynos4210_combiner_get_gpioin() splits
4
some of the combiner input lines further to connect them to multiple
5
different inputs on the combiner.
6
7
Because (unlike qemu_irq_split()) the TYPE_SPLIT_IRQ device has a
8
configurable number of outputs, we can do all this in one place, by
9
making exynos4210_init_board_irqs() add extra outputs to the splitter
10
device when it must be connected to more than one input on each
11
combiner.
12
13
We do this with a new data structure, the combinermap, which is an
14
array each of whose elements is a list of the interrupt IDs on the
15
combiner which must be tied together. As we loop through each
16
interrupt ID, if we find that it is the first one in one of these
17
lists, we configure the splitter device with eonugh extra outputs and
18
wire them up to the other interrupt IDs in the list.
19
20
Conveniently, for all the cases where this is necessary, the
21
lowest-numbered interrupt ID in each group is in the range of the
22
external combiner, so we only need to code for this in the first of
23
the two loops in exynos4210_init_board_irqs().
24
25
The old code in exynos4210_combiner_get_gpioin() which is being
26
deleted here had several problems which don't exist in the new code
27
in its handling of the multi-core timer interrupts:
28
(1) the case labels specified bits 4 ... 8, but bit '8' doesn't
29
exist; these should have been 4 ... 7
30
(2) it used the input irq[EXYNOS4210_COMBINER_GET_IRQ_NUM(1, bit + 4)]
31
multiple times as the input of several different splitters,
32
which isn't allowed
33
(3) in an apparent cut-and-paste error, the cases for all the
34
multi-core timer inputs used "bit + 4" even though the
35
bit range for the case was (intended to be) 4 ... 7, which
36
meant it was looking at non-existent bits 8 ... 11.
37
None of these exist in the new code.

"embedded in state struct" approach, so we can easily refer
3
to the object elsewhere during realize.

New patch
1
The only time we use the int_combiner_irq[] and ext_combiner_irq[]
2
arrays in the Exynos4210Irq struct is during realize of the SoC -- we
3
initialize them with the input IRQs of the combiner devices, and then
4
connect those to outputs of other devices in
5
exynos4210_init_board_irqs(). Now that the combiner objects are
6
easily accessible as s->int_combiner and s->ext_combiner we can make
7
the connections directly from one device to the other without going
8
via these arrays.
1
9
10
Since these are the only two remaining elements of Exynos4210Irq,
11
we can remove that struct entirely.

arm_cpu_vq_map_next_smaller(cpu, start_vq + 1U) and 1U"
6
Resolves: https://gitlab.com/qemu-project/qemu/-/issues/811
7
8
First, the aarch32 stub version of arm_cpu_vq_map_next_smaller,
9
returning 0, does exactly what Coverity reports. Remove it.
10
11
Second, the aarch64 version of arm_cpu_vq_map_next_smaller has
12
a set of asserts, but they don't cover the case in question.
13
Further, there is a fair amount of extra arithmetic needed to
14
convert from the 0-based zcr register, to the 1-base vq form,
15
to the 0-based bitmap, and back again. This can be simplified
16
by leaving the value in the 0-based form.
17
18
Finally, use test_bit to simplify the common case, where the
19
length in the zcr registers is in fact a supported length.

12
"The interrupt is cleared by writing any data value to the

However, later in section 11.2.2 it contradicts itself by saying:
16
17
"Writing 1 to bit 0 of RTCICR clears the RTCINTR flag."
18
19
The latter statement matches the PL031 TRM (DDI0224C), which says:
20
21
"Writing 1 to bit position 0 clears the corresponding interrupt.
22
Writing 0 has no effect."

Let's assume that the self-contradictory DDI0287B is in error, and
25
follow the reference manual for the device itself, by making the
26
register write-one-to-clear.
