Hi; this target-arm pull request has a collection of generally
1
Small pile of bug fixes for rc1. I've included my patches to get
2
fairly minor bugs to sneak in before 3.0 rc0 tomorrow...
2
our docs building with Sphinx 3, just for convenience...

New patch
[PULL 01/26] target/arm: Introduce neon_full_reg_offset
1
From: Richard Henderson <richard.henderson@linaro.org>

2
3
This function makes it clear that we're talking about the whole
4
register, and not the 32-bit piece at index 0. This fixes a bug
5
when running on a big-endian host.

[Qemu-devel] [PULL 09/11] hw/sd/omap_mmc: Split 'pseudo-reset' from 'power-on-reset'
[PULL 02/26] target/arm: Move neon_element_offset to translate.c

DeviceClass::reset models a "cold power-on" reset which can
3
This will shortly have users outside of translate-neon.c.inc.

also be used to powercycle a device; but there is no "hot reset"
5
(a.k.a. soft-reset) method available.

Multimedia Card (MMC/SD/SDIO) Interface [SPRU765A]
11
12
MMC_CON[11] Power-Up Control (POW)
13
This bit must be set to 1 before any valid transaction to either
14
MMC/SD or SPI memory cards.
15
When 1, the card is considered powered-up and the controller core
16
is enabled.
17
When 0, the card is considered powered-down (system dependent),
18
and the controller core logic is in pseudo-reset state. This is,
19
the MMC_STAT flags and the FIFO pointers are reset, any access to
20
MMC_DATA[DATA] has no effect, a write into the MMC.CMD register
21
is ignored, and a setting of MMC_SPI[STR] to 1 is ignored.
22
23
By splitting the 'pseudo-reset' code out of the 'power-on' reset
24
function, this patch fixes a latent bug in omap_mmc_write(MMC_CON)i
25
recently exposed by ecd219f7abb.

These instructions must perform the sve_access_check, but
3
These are the only users of neon_reg_offset, so remove that.
4
since they are implemented as NOPs there is no generated
5
code to elide when the access check fails.

[PULL 05/26] target/arm: Add read/write_neon_element32
1
From: Richard Henderson <richard.henderson@linaro.org>
1
2
3
Model these off the aa64 read/write_vec_element functions.
4
Use it within translate-neon.c.inc. The new functions do
5
not allocate or free temps, so this rearranges the calling
6
code a bit.

New patch
[PULL 06/26] target/arm: Expand read/write_neon_element32 to all MemOp
1
1
From: Richard Henderson <richard.henderson@linaro.org>
2
3
We can then use this to improve VMOV (scalar to gp) and
4
VMOV (gp to scalar) so that we simply perform the memory
5
operation that we wanted, rather than inserting or
6
extracting from a 32-bit quantity.
7
8
These were the last uses of neon_load/store_reg, so remove them.

[Qemu-devel] [PULL 07/11] tcg: Restrict check_size_impl to multiples of the line size
[PULL 07/26] target/arm: Rename neon_load_reg32 to vfp_load_reg32

Normally this is automatic in the size restrictions that are placed
3
The only uses of this function are for loading VFP
4
on vector sizes coming from the implementation. However, for the
4
single-precision values, and nothing to do with NEON.
5
legitimate size tuple [oprsz=8, maxsz=32], we need to clear the final
6
24 bytes of the vector register. Without this check, do_dup selects
7
TCG_TYPE_V128 and clears only 16 bytes.

[Qemu-devel] [PULL 05/11] hw/timer/cmsdk-apb-timer: run or stop timer on writes to RELOAD and VALUE
[PULL 12/26] target/arm: Fix float16 pairwise Neon ops on big-endian hosts
1
If the CMSDK APB timer is set up with a zero RELOAD value
1
In the neon_padd/pmax/pmin helpers for float16, a cut-and-paste error
2
then it will count down to zero, fire once and then stay
2
meant we were using the H4() address swizzler macro rather than the
3
at zero. From the point of view of the ptimer system, the
3
H2() which is required for 2-byte data. This had no effect on
4
timer is disabled; but the enable bit in the CTRL register
4
little-endian hosts but meant we put the result data into the
5
is still set and if the guest subsequently writes to the
5
destination Dreg in the wrong order on big-endian hosts.
6
RELOAD or VALUE registers this should cause the timer to
7
start counting down again.
8
9
Add code to the write paths for RELOAD and VALUE so that
10
we correctly restart the timer in this situation.
11
12
Conversely, if the new RELOAD and VALUE are both zero,
13
we should stop the ptimer.

Here the disassembly of 0x120..0x13f is using the data that is in
29
0x104..0x123.
30
31
This is caused by passing the wrong value to the read_memory_func().
32
The intention is that at this point in the loop the 'cap_buf' buffer
33
already contains 'csize' bytes of data for the instruction at guest
34
addr 'pc', and we want to read in an extra 'tsize' bytes. Those
35
extra bytes are therefore at 'pc + csize', not 'pc'. On the first
36
time through the loop 'csize' happens to be zero, so the initial read
37
of 32 bytes into cap_buf is correct and as long as the disassembly
38
never needs to read more data we return the correct information.
39
40
Use the correct guest address in the call to read_memory_func().

[Qemu-devel] [PULL 02/11] ptimer: Add TRIGGER_ONLY_ON_DECREMENT policy option
[PULL 21/26] target/arm: Get correct MMU index for other-security-state
1
The CMSDK timer behaviour is that an interrupt is triggered when the
1
In arm_v7m_mmu_idx_for_secstate() we get the 'priv' level to pass to
2
counter counts down from 1 to 0; however one is not triggered if the
2
armv7m_mmu_idx_for_secstate_and_priv() by calling arm_current_el().
3
counter is manually set to 0 by a guest write to the counter register.
3
This is incorrect when the security state being queried is not the
4
Currently ptimer can't handle this; add a policy option to allow
4
current one, because arm_current_el() uses the current security state
5
a ptimer user to request this behaviour.
5
to determine which of the banked CONTROL.nPRIV bits to look at.
6
The effect was that if (for instance) Secure state was in privileged
7
mode but Non-Secure was not then we would return the wrong MMU index.
8
9
The only places where we are using this function in a way that could
10
trigger this bug are for the stack loads during a v8M function-return
11
and for the instruction fetch of a v8M SG insn.
12
13
Fix the bug by expanding out the M-profile version of the
14
arm_current_el() logic inline so it can use the passed in secstate
15
rather than env->v7m.secure.

[PULL 22/26] configure: Test that gio libs from pkg-config work
1
On some hosts (eg Ubuntu Bionic) pkg-config returns a set of
2
libraries for gio-2.0 which don't actually work when compiling
3
statically. (Specifically, the returned library string includes
4
-lmount, but not -lblkid which -lmount depends upon, so linking
5
fails due to missing symbols.)
1
6
7
Check that the libraries work, and don't enable gio if they don't,
8
in the same way we do for gnutls.

[PULL 23/26] hw/intc/arm_gicv3_cpuif: Make GIC maintenance interrupts work
1
In gicv3_init_cpuif() we copy the ARMCPU gicv3_maintenance_interrupt
2
into the GICv3CPUState struct's maintenance_irq field. This will
3
only work if the board happens to have already wired up the CPU
4
maintenance IRQ before the GIC was realized. Unfortunately this is
5
not the case for the 'virt' board, and so the value that gets copied
6
is NULL (since a qemu_irq is really a pointer to an IRQState struct
7
under the hood). The effect is that the CPU interface code never
8
actually raises the maintenance interrupt line.
1
9
10
Instead, since the GICv3CPUState has a pointer to the CPUState, make
11
the dereference at the point where we want to raise the interrupt, to
12
avoid an implicit requirement on board code to wire things up in a
13
particular order.

[PULL 24/26] scripts/kerneldoc: For Sphinx 3 use c:macro for macros with arguments
1
The kerneldoc script currently emits Sphinx markup for a macro with
2
arguments that uses the c:function directive. This is correct for
3
Sphinx versions earlier than Sphinx 3, where c:macro doesn't allow
4
documentation of macros with arguments and c:function is not picky
5
about the syntax of what it is passed. However, in Sphinx 3 the
6
c:macro directive was enhanced to support macros with arguments,
7
and c:function was made more picky about what syntax it accepted.
1
8
9
When kerneldoc is told that it needs to produce output for Sphinx
10
3 or later, make it emit c:function only for functions and c:macro
11
for macros with arguments. We assume that anything with a return
12
type is a function and anything without is a macro.
13
14
This fixes the Sphinx error:

[Qemu-devel] [PULL 10/11] boards.h: Remove doc comment reference to nonexistent function
[PULL 25/26] qemu-option-trace.rst.inc: Don't use option:: markup
1
commit b08199c6fbea1 accidentally added a reference to a doc
1
Sphinx 3.2 is pickier than earlier versions about the option:: markup,
2
comment to a nonexistent memory_region_allocate_aux_memory().
2
and complains about our usage in qemu-option-trace.rst:
3
This was a leftover from a previous version of the patchset
4
which defined memory_region_allocate_aux_memory() for
5
"allocate RAM MemoryRegion and register it for migration"
6
and left "memory_region_init_ram()" with its original semantics
7
of "allocate RAM MR but do not register for migration". In
8
the end we decided on the approach of "memory_region_init_ram()
9
registers the MR for migration, and memory_region_init_ram_nomigrate()
10
is a new function which does not", but this comment change
11
got left in by mistake. Revert that part of the commit.

../../docs/qemu-option-trace.rst.inc:4:Malformed option description
5
'[enable=]PATTERN', should look like "opt", "-opt args", "--opt args",
6

7
8
In this file, we're really trying to document the different parts of
9
the top-level --trace option, which qemu-nbd.rst and qemu-img.rst
10
have already introduced with an option:: markup. So it's not right
11
to use option:: here anyway. Switch to a different markup
12
(definition lists) which gives about the same formatted output.
13
14
(Unlike option::, this markup doesn't produce index entries; but
15
at the moment we don't do anything much with indexes anyway, and
16
in any case I think it doesn't make much sense to have individual
17
index entries for the sub-parts of the --trace option.)

[PULL 26/26] tests/qtest/npcm7xx_rng-test: Disable randomness tests
1
Currently we use memory_region_init_rom_nomigrate() to create
1
The randomness tests in the NPCM7xx RNG test fail intermittently
2
the "dp3893x-prom" memory region, and we don't manually register
2
but fairly frequently. On my machine running the test in a loop:
3
it with vmstate_register_ram(). This currently means that its
3
while QTEST_QEMU_BINARY=./qemu-system-aarch64 ./tests/qtest/npcm7xx_rng-test; do true; done
4
contents are migrated but as a ram block whose name is the empty
5
string; in future it may mean they are not migrated at all. Use
6
memory_region_init_ram() instead.
7
4
8
Note that this is a a cross-version migration compatibility break
5
will fail in less than a minute with an error like:
9
for the MIPS "magnum" and "pica61" machines.
6
ERROR:../../tests/qtest/npcm7xx_rng-test.c:256:test_first_byte_runs:

8
9
(Failures have been observed on all 4 of the randomness tests,
10
not just first_byte_runs.)
11
12
It's not clear why these tests are failing like this, but intermittent
13
failures make CI and merge testing awkward, so disable running them
14
unless a developer specifically sets QEMU_TEST_FLAKY_RNG_TESTS when
15
running the test suite, until we work out the cause.
