[PULL 0/5] target-arm queue
[PULL v2 00/11] target-arm queue
1
Hi; this is a collection of mostly GIC related patches for rc3.
1
Massively slimmed down v2: MemTag broke bsd-user, and the npcm7xx
2
The "Update cached state after LPI state changes" fix is important
2
ethernet device failed 'make check' on big-endian hosts.
3
and fixes what would otherwise be a regression since we enable the
4
ITS by default in the virt board now. The others are not regressions
5
but I think are OK for rc3 as they're fairly self contained (and two
6
of them are fixes to new-in-6.2 functionality).

[PULL 1/5] hw/arm/virt: Extend nested and mte checks to hvf
Deleted patch
1
From: Alexander Graf <agraf@csgraf.de>
2
1
3
The virt machine has properties to enable MTE and Nested Virtualization
4
support. However, its check to ensure the backing accel implementation
5
supports it today only looks for KVM and bails out if it finds it.
6
7
Extend the checks to HVF as well as it does not support either today.
8
This will cause QEMU to print a useful error message rather than
9
silently ignoring the attempt by the user to enable either MTE or
10
the Virtualization extensions.

[PULL 3/5] hw/intc/arm_gicv3: Update cached state after LPI state changes
Deleted patch
1
The logic of gicv3_redist_update() is as follows:
2
* it must be called in any code path that changes the state of
3
(only) redistributor interrupts
4
* if it finds a redistributor interrupt that is (now) higher
5
priority than the previous highest-priority pending interrupt,
6
then this must be the new highest-priority pending interrupt
7
* if it does *not* find a better redistributor interrupt, then:
8
- if the previous state was "no interrupts pending" then
9
the new state is still "no interrupts pending"
10
- if the previous best interrupt was not a redistributor
11
interrupt then that remains the best interrupt
12
- if the previous best interrupt *was* a redistributor interrupt,
13
then the new best interrupt must be some non-redistributor
14
interrupt, but we don't know which so must do a full scan
15
1
16
In commit 17fb5e36aabd4b2c125 we effectively added the LPI interrupts
17
as a kind of "redistributor interrupt" for this purpose, by adding
18
cs->hpplpi to the set of things that gicv3_redist_update() considers
19
before it gives up and decides to do a full scan of distributor
20
interrupts. However we didn't quite get this right:
21
* the condition check for "was the previous best interrupt a
22
redistributor interrupt" must be updated to include LPIs
23
in what it considers to be redistributor interrupts
24
* every code path which updates the LPI state which
25
gicv3_redist_update() checks must also call gicv3_redist_update():
26
this is cs->hpplpi and the GICR_CTLR ENABLE_LPIS bit
27
28
This commit fixes this by:
29
* correcting the test on cs->hppi.irq in gicv3_redist_update()
30
* making gicv3_redist_update_lpi() always call gicv3_redist_update()
31
* introducing a new gicv3_redist_update_lpi_only() for the one
32
callsite (the post-load hook) which must not call
33
gicv3_redist_update()
34
* making gicv3_redist_lpi_pending() always call gicv3_redist_update(),
35
either directly or via gicv3_redist_update_lpi()
36
* removing a couple of now-unnecessary calls to gicv3_redist_update()
37
from some callers of those two functions
38
* calling gicv3_redist_update() when the GICR_CTLR ENABLE_LPIS
39
bit is cleared
40
41
(This means that the not-file-local gicv3_redist_* LPI related
42
functions now all take care of the updates of internally cached
43
GICv3 information, in the same way the older functions
44
gicv3_redist_set_irq() and gicv3_redist_send_sgi() do.)
45
46
The visible effect of this bug was that when the guest acknowledged
47
an LPI by reading ICC_IAR1_EL1, we marked it as not pending in the
48
LPI data structure but still left it in cs->hppi so we would offer it
49
to the guest again. In particular for setups using an emulated GICv3
50
and ITS and using devices which use LPIs (ie PCI devices) a Linux
51
guest would complain "irq 54: nobody cared" and then hang. (The hang
52
was intermittent, presumably depending on the timing between
53
different interrupts arriving and being completed.)

[PULL 4/5] hw/intc/arm_gicv3: Add new gicv3_intid_is_special() function
Deleted patch
1
The GICv3/v4 pseudocode has a function IsSpecial() which returns true
2
if passed a "special" interrupt ID number (anything between 1020 and
3
1023 inclusive). We open-code this condition in a couple of places,
4
so abstract it out into a new function gicv3_intid_is_special().

[PULL 5/5] hw/intc/arm_gicv3: fix handling of LPIs in list registers
Deleted patch
1
It is valid for an OS to put virtual interrupt ID values into the
2
list registers ICH_LR<n> which are greater than 1023. This
3
corresponds to (for example) KVM using the in-kernel emulated ITS to
4
give a (nested) guest an ITS. LPIs are delivered by the L1 kernel to
5
the L2 guest via the list registers in the same way as non-LPI
6
interrupts.
7
1
8
QEMU's code for handling writes to ICV_IARn (which happen when the L2
9
guest acknowledges an interrupt) and to ICV_EOIRn (which happen at
10
the end of the interrupt) did not consider LPIs, so it would
11
incorrectly treat interrupt IDs above 1023 as invalid. Fix this by
12
using the correct condition, which is gicv3_intid_is_special().
13
14
Note that the condition in icv_dir_write() is correct -- LPIs
15
are not valid there and so we want to ignore both "special" ID
16
values and LPIs.
17
18
(In the pseudocode this logic is in:
19
- VirtualReadIAR0(), VirtualReadIAR1(), which call IsSpecial()
20
- VirtualWriteEOIR0(), VirtualWriteEOIR1(), which call
21
VirtualIdentifierValid(data, TRUE) meaning "LPIs OK"
22
- VirtualWriteDIR(), which calls VirtualIdentifierValid(data, FALSE)
23
meaning "LPIs not OK")
24
25
This bug doesn't seem to have any visible effect on Linux L2 guests
26
most of the time, because the two bugs cancel each other out: we
27
neither mark the interrupt active nor deactivate it. However it does
28
mean that the L2 vCPU priority while the LPI handler is running will
29
not be correct, so the interrupt handler could be unexpectedly
30
interrupted by a different interrupt.
31
32
(NB: this has nothing to do with using QEMU's emulated ITS.)
