Arm queue; not huge but I figured I might as well send it out since
I've been doing code review today and there's no queue of unprocessed
pullreqs...

thanks

The AArch64 view of CLIDR_EL1 extends the ICB field to include also bit
32, as well as adding a Ttype<n> field when FEAT_MTE is implemented.
Extend the clidr field to be able to hold this context.

In commit 1982e1602d15 we added a new qemu-storage-daemon(1) manpage.
At the moment new manpages have to be listed both in the conf.py for
Sphinx and also in docs/meson.build for Meson. We forgot the second
of those -- correct the omission.

  To: qemu-devel

When we first converted our documentation to Sphinx, we split it into
multiple manuals (system, interop, tools, etc), which are all built
separately.  The primary driver for this was wanting to be able to
avoid shipping the 'devel' manual to end-users.  However, this is
working against the grain of the way Sphinx wants to be used and
causes some annoyances:
 * Cross-references between documents become much harder or
   possibly impossible
 * There is no single index to the whole documentation
 * Within one manual there's no links or table-of-contents info
   that lets you easily navigate to the others
 * The devel manual doesn't get published on the QEMU website
   (it would be nice to able to refer to it there)

Merely hiding our developer documentation from end users seems like
it's not enough benefit for these costs.  Combine all the
documentation into a single manual (the same way that the readthedocs
site builds it) and install the whole thing.  The previous manual
divisions remain as the new top level sections in the manual.

 * The per-manual conf.py files are no longer needed
 * The man_pages[] specifications previously in each per-manual
   conf.py move to the top level conf.py
 * docs/meson.build logic is simplified as we now only need to run
   Sphinx once for the HTML and then once for the manpages5B
 * The old index.html.in that produced the top-level page with
   links to each manual is no longer needed

Unfortunately this means that we now have to build the HTML
documentation into docs/manual in the build tree rather than directly
into docs/; otherwise it is too awkward to ensure we install only the
built manual and not also the dependency info, stamp file, etc.  The
manual still ends up in the same place in the final installed
directory, but anybody who was consulting documentation from within
the build tree will have to adjust where they're looking.

In commit cd8be50e58f63413c0 we converted the A32 coprocessor
insns to decodetree. This accidentally broke XScale/iWMMXt insns,
because it moved the handling of "cp insns which are handled
by looking up the cp register in the hashtable" from after the
call to the legacy disas_xscale_insn() decode to before it,
with the result that all XScale/iWMMXt insns now UNDEF.

Update valid_cp() so that it knows that on XScale cp 0 and 1
are not standard coprocessor instructions; this will cause
the decodetree trans_ functions to ignore them, so that
execution will correctly get through to the legacy decode again.

A copy-and-paste error meant that the return value for register offset 0x44
(the RX Status FIFO PEEK register) returned a byte from a bogus offset in
the rx status FIFO. Fix the typo.

The lan9118 code mostly uses symbolic constants for register offsets;
the exceptions are those which the datasheet doesn't give an official
symbolic name to.

Add some names for the registers which don't already have them, based
on the longer names they are given in the memory map.

From: Hao Wu <wuhaotsh@google.com>

This patch allows NPCM7XX CLK module to compute clocks that are used by
other NPCM7XX modules.

Add a new struct NPCM7xxClockConverterState which represents a
single converter.  Each clock converter in CLK module represents one
converter in NPCM7XX CLK Module(PLL, SEL or Divider). Each converter
takes one or more input clocks and converts them into one output clock.
They form a clock hierarchy in the CLK module and are responsible for
outputing clocks for various other modules in an NPCM7XX SoC.

Each converter has a function pointer called "convert" which represents
the unique logic for that converter.

The clock contains two initialization information: ConverterInitInfo and
ConverterConnectionInfo. They represent the vertices and edges in the
clock diagram respectively.

From: Hao Wu <wuhaotsh@google.com>

The ADC is part of NPCM7XX Module. Its behavior is controled by the
ADC_CON register. It converts one of the eight analog inputs into a
digital input and stores it in the ADC_DATA register when enabled.

Users can alter input value by using qom-set QMP command.

  To: qemu-devel

From: Hao Wu <wuhaotsh@google.com>

The PWM module is part of NPCM7XX module. Each NPCM7XX module has two
identical PWM modules. Each module contains 4 PWM entries. Each PWM has
two outputs: frequency and duty_cycle. Both are computed using inputs
from software side.

This module does not model detail pulse signals since it is expensive.
It also does not model interrupts and watchdogs that are dependant on
the detail models. The interfaces for these are left in the module so
that anyone in need for these functionalities can implement on their
own.

The user can read the duty cycle and frequency using qom-get command.

  To: qemu-devel

From: Hao Wu <wuhaotsh@google.com>

A device shouldn't access its parent object which is QOM internal.
Instead it should use type cast for this purporse. This patch fixes this
issue for all NPCM7XX Devices.

Hi; Coverity reports a possibly-overflowing arithmetic operation here
(CID 1442342):

Here all of p->cmr, p->cnr and NPCM7XX_PWM_MAX_DUTY are 32-bits,
so we calculate the whole expression using 32-bit arithmetic
before assigning it to a 64-bit variable. This could be
fixed using eg a cast of NPCM7XX_PWM_MAX_DUTY to uint64_t.

Incidentally, we don't actually do any 64-bit
arithmetic calculations on 'duty' and we return
a uint32_t from this function, so 'duty' itself could
be a uint32_t, I think...

Since NPCM7XX_PWM_MAX_DUTY =1,000,000 and p->cmr can have up to 65535, The
overflow is possible. We might want to cast NPCM7XX_PWM_MAX_DUTY to
uint64_t or #define NPCM7XX_PWM_MAX_DUTY 1000000ULL
duty itself could be a uint32_t as you point out. Since p->cmr is less than
p->cnr in this line, duty cannot exceed NPCM7XX_PWM_MAX_DUTY, so there's no
overflow after this computation.

Thank you for finding this!

OK thanks. Since the datasheet is not public, better document
the reserved/unused bits to avoid further questioning later ;)

Is that a spurious error (building with Clang)?

I don't see this error. It could be some error in the clock that the timer
module does not get a correct clock input.
How do you reproduce this?

This intermittent is still with us:

/arm/npcm7xx_timer/tim[2]/timer[0]/periodic_interrupt: **
ERROR:../../tests/qtest/npcm7xx_timer-test.c:475:test_periodic_interrupt:

I was able to reproduce it by running the test in a tight loop:

while QTEST_QEMU_BINARY=./build/x86/qemu-system-arm
./build/x86/tests/qtest/npcm7xx_timer-test ; do true ;done

and eventually it hit the assert.

It looks like the interrupt fires consistently with the status bit. It
also only happens once during that loop of four timer periods (the
test calls g_test_set_nonfatal_assertions() so we would have seen more
failures reported if this wasn't the case).

I'm wondering if the clock_step_next() call is occasionally hitting a
different timer, causing it to return before it has advanced to the
next period of the timer module? If so, it might help to use
clock_step(tim_calculate_step(...)) like some of the other tests do.
This would also verify that the timer is actually firing at the right
interval.

This line causes a build warning with the latest code:

../../../docs/meson.build:74: WARNING: Project targets '>=0.61.3' but 
uses feature deprecated since '0.60.0': install_subdir with empty 
directory. It worked by accident and is buggy. Use install_emptydir instead.

It looks like `qemu_docdir` is no longer defined anywhere.

I still did not find out whether this is an issue which needs a fix for 7.2.

It's defined by the top-level meson.build, in line 39:

qemu_docdir = get_option('docdir') / get_option('qemu_suffix')

The warning from meson is not about the value of install_dir,
though : it's saying "the directory you asked me to install from
the build tree doesn't exist, I'm going to create an empty
subdirectory in the install destination, but there's better ways
to do that if that's what you were intending to do". So the
question is why your build tree doesn't have the documentation
built in it -- it should be in $BUILDDIR/docs/manual/ .

Mostly straightforward bugfixes. The new Xilinx devices are
arguably 'new feature', but they're fixing a regression where
our changes to PSCI in commit 3f37979bf mean that EL3 guest
code now needs to talk to a proper emulated power-controller
device to turn on secondary CPUs; and it's not yet rc1 and
they only affect the Xilinx board, so it seems OK to me.

thanks

FYI Prasad mentioned a CVE was requested:
https://www.mail-archive.com/qemu-devel@nongnu.org/msg778659.html

As you said it is an odd configuration, I am not sure it is worth
to wait for the CVE number to add it to the commit (which helps
downstream distributions tracking these).

[updating]

Just got detail from Prasad on IRC, it usually takes ~1 day to get
the CVE number assigned, so maybe worth postponing this until tomorrow.

Prasad, can you reply to this message ASAP once you get the number?

Thanks,

Phil.

Mostly just bug fixes. The important one here is
  hw/intc/arm_gic: Fix interrupt ID in GICD_SGIR register
which fixes a buffer overrun that's a security issue if you're running
KVM on Arm with kernel-irqchip=off (which hopefully nobody is doing in
a security context, because kernel-irqchip=on is the default and the
sensible choice for performance).
