[PATCH v7 01/22] configure: Allow passing extra Objective C compiler flags

[Philippe Mathieu-Daudé]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

We can pass C/CPP/LD flags via CFLAGS/CXXFLAGS/LDFLAGS environment
variables, or via configure --extra-cflags / --extra-cxxflags /
--extra-ldflags options. Provide similar behavior for Objective C:
use existing flags from $OBJCFLAGS, or passed via --extra-objcflags.

[PATCH v7 02/22] tests/fp/berkeley-testfloat-3: Ignore ignored #pragma directives

[Philippe Mathieu-Daudé]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

Since we already use -Wno-unknown-pragmas, we can also use
-Wno-ignored-pragmas. This silences hundred of warnings using
clang 13 on macOS Monterey:

  [409/771] Compiling C object tests/fp/libtestfloat.a.p/berkeley-testfloat-3_source_test_az_f128_rx.c.o

  #pragma STDC FENV_ACCESS ON
               ^
  1 warning generated.

[PATCH v7 05/22] hvf: Remove deprecated hv_vcpu_flush() calls

[Philippe Mathieu-Daudé]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

When building on macOS 11 [*], we get:

  In file included from ../target/i386/hvf/hvf.c:59:
  ../target/i386/hvf/vmx.h:174:5: error: 'hv_vcpu_flush' is deprecated: first deprecated in macOS 11.0 - This API has no effect and always returns HV_UNSUPPORTED [-Werror,-Wdeprecated-declarations]
      hv_vcpu_flush(vcpu);
      ^
  /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Hypervisor.framework/Headers/hv.h:364:20: note: 'hv_vcpu_flush' has been explicitly marked deprecated here
  extern hv_return_t hv_vcpu_flush(hv_vcpuid_t vcpu)
                     ^

Since this call "has no effect", simply remove it ¯\_(ツ)_/¯

Not very useful deprecation doc:
https://developer.apple.com/documentation/hypervisor/1441386-hv_vcpu_flush

[*] Also 10.15 (Catalina):

[PATCH v7 06/22] hvf: Fix OOB write in RDTSCP instruction decode

[Philippe Mathieu-Daudé]

From: Cameron Esfahani <dirty@apple.com>

A guest could craft a specific stream of instructions that will have QEMU
write 0xF9 to inappropriate locations in memory.  Add additional asserts
to check for this.  Generate a #UD if there are more than 14 prefix bytes.

[PATCH v7 11/22] coreaudio: Always return 0 in handle_voice_change

[Philippe Mathieu-Daudé]

From: Akihiko Odaki <akihiko.odaki@gmail.com>

handle_voice_change() is a CoreAudio callback function as of CoreAudio type
AudioObjectPropertyListenerProc, and for the latter MacOSX.sdk/System/
Library/Frameworks/CoreAudio.framework/Headers/AudioHardware.h
says "The return value is currently unused and should always be 0.".

[PATCH v7 12/22] audio: Rename coreaudio extension to use Objective-C compiler

[Philippe Mathieu-Daudé]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

The coreaudio library includes Objective-C declarations (using the
caret '^' symbol to declare block references [*]). When building
with a C compiler we get:

  [175/839] Compiling C object libcommon.fa.p/audio_coreaudio.c.o
    In file included from /Library/Developer/CommandLineTools/SDKs/MacOSX12.sdk/System/Library/Frameworks/CoreAudio.framework/Headers/CoreAudio.h:18,
                     from ../../audio/coreaudio.c:26:
    /Library/Developer/CommandLineTools/SDKs/MacOSX12.sdk/System/Library/Frameworks/CoreAudio.framework/Headers/AudioHardware.h:162:2: error: expected identifier or '(' before '^' token

          |  ^
    FAILED: libcommon.fa.p/audio_coreaudio.c.o

Rename the file to use the Objective-C default extension (.m) so
meson calls the correct compiler.

[PATCH v7 13/22] osdep: Avoid using Clang-specific __builtin_available()

[Philippe Mathieu-Daudé]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

Remove the Clang specific __builtin_available() to allow building
with GCC, otherwise we get:

  include/qemu/osdep.h: In function 'qemu_thread_jit_write':
  include/qemu/osdep.h:787:9: warning: implicit declaration of function '__builtin_available'; did you mean '__builtin_scalbl'? [-Wimplicit-function-declaration]

        |                                  )

Beside, on macOS Catalina we get 2254 times:

  include/qemu/osdep.h:780:5: warning: 'pthread_jit_write_protect_np' is only available on macOS 11.0 or newer [-Wunguarded-availability-new]
      pthread_jit_write_protect_np(true);
      ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

Fix by using a stricker toolchain version low range, replacing
MAC_OS_X_VERSION_MAX_ALLOWED by MAC_OS_X_VERSION_MIN_REQUIRED.

Commit 235b523dba ("meson: Use find_program() to resolve the

the script is still resolved for each target. Move the check
earlier, before processing each target.

[PATCH v7 18/22] ui/cocoa: add option to disable left-command forwarding to guest

[Philippe Mathieu-Daudé]

From: Carwyn Ellis <carwynellis@gmail.com>

When switching between guest and host on a Mac using command-tab the
command key is sent to the guest which can trigger functionality in the
guest OS. Specifying left-command-key=off disables forwarding this key
to the guest. Defaults to enabled.

Also updated the cocoa display documentation to reference the new
left-command-key option along with the existing show-cursor option.

[PATCH v7 19/22] ui/cocoa: release mouse when user switches away from QEMU window

[Philippe Mathieu-Daudé]

From: Carwyn Ellis <carwynellis@gmail.com>

This resolves an issue where using command-tab to switch between QEMU
and other windows on the host can leave the mouse pointer visible.

By releasing the mouse when the user switches away, the user must left
click on the QEMU window when switching back in order to hide the
pointer and return control to the guest.

This appraoch ensures that the calls to NSCursor hide and unhide are
always balanced and thus work correctly when invoked.

[PATCH v7 20/22] ui/cocoa: capture all keys and combos when mouse is grabbed

[Philippe Mathieu-Daudé]

From: Gustavo Noronha Silva <gustavo@noronha.dev.br>

Applications such as Gnome may use Alt-Tab and Super-Tab for different
purposes, some use Ctrl-arrows so we want to allow qemu to handle
everything when it captures the mouse/keyboard.

However, Mac OS handles some combos like Command-Tab and Ctrl-arrows
at an earlier part of the event handling chain, not letting qemu see it.

We add a global Event Tap that allows qemu to see all events when the
mouse is grabbed. Note that this requires additional permissions.

[PATCH v7 21/22] ui/cocoa: add option to swap Option and Command

[Philippe Mathieu-Daudé]

From: Gustavo Noronha Silva <gustavo@noronha.dev.br>

On Mac OS X the Option key maps to Alt and Command to Super/Meta. This change
swaps them around so that Alt is the key closer to the space bar and Meta/Super
is between Control and Alt, like on non-Mac keyboards.

It is a cocoa display option, disabled by default.

[PATCH v7 22/22] gitlab-ci: Support macOS 12 via cirrus-run

[Philippe Mathieu-Daudé]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

Add support for macOS 12 build on Cirrus-CI, similarly to commit
0e103a65ba1 ("gitlab: support for ... macOS 11 via cirrus-run"),
but with the following differences:
 - Enable modules (configure --enable-modules)
 - Do not run softfloat3 tests (make check-softfloat)
 - Run Aarch64 qtests instead of x86_64 ones

Generate the vars file by calling 'make lcitool-refresh'.

Basically fine for me, but can we really run additional cirrus-ci jobs by 
default? IIRC the parallel execution of those were quite limited for the 
free tier, so did you look close that we don't run into additional timeouts 
yet, due to delayed cirrus-ci jobs?

You can run 2 jobs in parallel in Cirrus. Beyond that they
get queued/serialized

We have a 1 hour job timeout.

We have to expect jobs will sometimes run slower than normal.

IOW if we have a job on Cirrus taking 30 minutes normally, we
expect it will sometimes take 45 minutes.

All this means that if we want Cirrus to be reliable and not
time out, we can really only have 2 jobs by default, unless
we can get the job execution time down to around 20 minutes
to allow for serialization.

We used to have terrible problems with cirrus timeouts when
we were running 4 jobs concurrently (2 on staging and 2 on
master). We addressed that in 9968de0a4a5470bd7b98dcd2fae5d5269908f16b
by disabling the jobs on master.

IOW, we really need to choose 1 macOS job and 1 FreeBSD job
and others need to be marked manual.

Regards,
Daniel

Not sure which job to choose yet. Per the first google hits we
still want to cover Catalina first:
https://www.statista.com/statistics/944559/worldwide-macos-version-market-share/

Would it be beneficial to have a 1 per OS job during PR, and
other jobs run nightly (once a day, not per PR)?

Yes, in the repo CI settings create a scheduled job, using cron syntax.
Relies on the job "rules" in the config file not excluding scheduled
execution of course.

My general gut feeling is usually to prioritize testing older versions
as they tend to be more widely used, and we want to avoid regresions
on stuff that has been around the longest. Compatibility problems with
new releases tend to get reported by users/maintainers and would not
be regressions, but rather enhancements to support the new platform.

But it is not really an easy decision, as clearly we would prefer to
test both old and new if we had the ability.

Having one as a nightly job is a reasonable compromise. 

With regards,
Daniel

...that page says that the figures for Catalina are "incorrectly
high", so not a very useful set of data for these purposes I think.

Note that technically speaking Catalina (10.15) has already fallen off
the end of our support policy (which currently requires Big Sur (11)
and Monterey (12) support, as the two most recent versions). My
personal macos x86 laptop is still running Catalina, though,
because Big Sur dropped support for that hardware :-/
That suggests that maybe Big Sur would be what we should go for
now if we have to pick just one for the CI.

OK. Since I'm running Monterey (12) on my workstation, I'll make this
job manual / nightly, and keep the Big Sur (11) on CI.

I'll let Daniel / Thomas / Alex decide which FreeBSD job to demote to
manual.

I had review comments on the version of this patch in v5 which
still need to be addressed:

Thanks for pointing at your comments, I totally missed them.

Hi Philippe, I did not find v6 somehow,

and I was looking for patch:

"[PATCH v5 06/16] hvf: Enable RDTSCP support"

was it dropped / merged with something else? I do not see it in latest git, nor in this respin,
maybe it is in your tree somewhere?

Thanks,

Claudio

The patch stayed unreviewed during 2 months, so I dropped it.

Now it got at least a Tested-by tag from Silvio, I'll include it in the
next PR.
