[PULL 01/25] hw/input/pckbd: Open-code i8042_setup_a20_line() wrapper

[Philippe Mathieu-Daudé]

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

Since the named GPIO lines are a "public" interface to the device,
we can directly call qdev_connect_gpio_out_named(), making it
consistent with how the other A20 input source (port92) is wired.

[PULL 02/25] hw/sysbus: Inline and remove sysbus_add_io()

[Philippe Mathieu-Daudé]

sysbus_add_io(...) is a simple wrapper to
memory_region_add_subregion(get_system_io(), ...).
It is used in 3 places; inline it directly.

Rationale: we want to move to an explicit I/O bus,
rather that an implicit one. Besides in heterogeneous
setup we can have more than one I/O bus.

[PULL 05/25] hw/ppc/ppc4xx_pci: Move ppc4xx_pci.c to hw/pci-host/

[Philippe Mathieu-Daudé]

ppc4xx_pci.c is moved from the target specific ppc_ss[] meson
source set to pci_ss[] which is common to all targets: the
object is built once.

Declare PPC4XX_PCI selector in pci-host/Kconfig.

[PULL 09/25] hw/i386/pc: Store pointers to IDE buses in PCMachineState

[Philippe Mathieu-Daudé]

From: Peter Maydell <peter.maydell@linaro.org>

Add the two IDE bus BusState pointers to the set we keep in PCMachineState.
This allows us to avoid passing them to pc_cmos_init(), and also will
allow a refactoring of how we call pc_cmos_init_late().

[PULL 10/25] hw/i386/pc: Do pc_cmos_init_late() from pc_machine_done()

[Philippe Mathieu-Daudé]

From: Peter Maydell <peter.maydell@linaro.org>

In the i386 PC machine, we want to run the pc_cmos_init_late()
function only once the IDE and floppy drive devices have been set up.
We currently do this using qemu_register_reset(), and then have the
function call qemu_unregister_reset() on itself, so it runs exactly
once.

This was an expedient way to do it back in 2010 when we first added
this (in commit c0897e0cb94e8), but now we have a more obvious point
to do "machine initialization that has to happen after generic device
init": the machine-init-done hook.

Do the pc_cmos_init_late() work from our existing PC machine init
done hook function, so we can drop the use of qemu_register_reset()
and qemu_unregister_reset().

Because the pointers to the devices we need (the IDE buses and the
RTC) are now all in the machine state, we don't need the
pc_cmos_init_late_arg struct and can just pass the PCMachineState
pointer.

The attribute isn't user-changeable and only true for pc-based machines. Turn it
into a class attribute which allows for inlining pc_guest_info_init() into
pc_machine_initfn().

[PULL 13/25] hw/i386/pc: Defer smbios_set_defaults() to machine_done

[Philippe Mathieu-Daudé]

From: Bernhard Beschow <shentey@gmail.com>

Handling most of smbios data generation in the machine_done notifier is similar
to how the ARM virt machine handles it which also calls smbios_set_defaults()
there. The result is that all pc machines are freed from explicitly worrying
about smbios setup.

[PULL 14/25] hw/i386/pc: Confine system flash handling to pc_sysfw

[Philippe Mathieu-Daudé]

From: Bernhard Beschow <shentey@gmail.com>

Rather than distributing PC system flash handling across three files, let's
confine it to one. Now, pc_system_firmware_init() creates, configures and cleans
up the system flash which makes the code easier to understand. It also avoids
the extra call to pc_system_flash_cleanup_unused() in the Xen case.

Hi Bernhard,

this patch breaks QEMU on my system.

./qemu-system-x86_64 -machine q35,pflash0=pflash0-storage -blockdev
driver=file,node-name=pflash0-storage,filename=/usr/share/qemu/ovmf-x86_64.bin,read-only=true
qemu-system-x86_64: Property 'pc-q35-9.0-machine.pflash0' not found

I had to revert cb05cc1602 ("hw/i386/pc_sysfw: Inline
pc_system_flash_create() and remove it") and 6f6ad2b245 ("hw/i386/pc:
Confine system flash handling to pc_sysfw") to make it work again.

With best regards,
Volker

In my tests I've followed https://wiki.archlinux.org/title/QEMU#Booting_in_UEFI_mode for both pc and q35 machine, and therefore missed the machine properties. If there is no way to fix it with compat properties or the like, I propose to revert the two patches until a different solution is found.

Best regards,
Bernhard

[PULL 15/25] hw/i386/pc_sysfw: Inline pc_system_flash_create() and remove it

[Philippe Mathieu-Daudé]

From: Bernhard Beschow <shentey@gmail.com>

pc_system_flash_create() checked for pcmc->pci_enabled which is redundant since
its caller already checked it. The method can be turned into just two lines, so
inline and remove it.

[PULL 16/25] hw/i386/pc_q35: Populate interrupt handlers before realizing LPC PCI function

[Philippe Mathieu-Daudé]

From: Bernhard Beschow <shentey@gmail.com>

The interrupt handlers need to be populated before the device is realized since
internal devices such as the RTC are wired during realize(). If the interrupt
handlers aren't populated, devices such as the RTC will be wired with a NULL
interrupt handler, i.e. MC146818RtcState::irq is NULL.

[PULL 18/25] hw/ide: Add the possibility to disable the CompactFlash device in the build

[Philippe Mathieu-Daudé]

From: Thomas Huth <thuth@redhat.com>

For distros like downstream RHEL, it would be helpful to allow to disable
the CompactFlash device. For making this possible, we need a separate
Kconfig switch for this device, and the code should reside in a separate
file. Let's also introduce a new header ide-dev.h which can be used to
collect definitions related to IDE devices.

[PULL 19/25] hw/ide: Split qdev.c into ide-bus.c and ide-dev.c

[Philippe Mathieu-Daudé]

From: Thomas Huth <thuth@redhat.com>

qdev.c is a mixture between IDE bus specific functions and IDE device
functions. Let's split it up to make it more obvious which part is
related to bus handling and which part is related to device handling.

[PULL 20/25] hw/ide: Move IDE DMA related definitions to a separate header ide-dma.h

[PULL 24/25] hw/ide: Stop exposing internal.h to non-IDE files

[Philippe Mathieu-Daudé]

From: Thomas Huth <thuth@redhat.com>

include/hw/ide/internal.h is currently included by include/hw/ide/pci.h
and thus exposed to a lot of files that are not part of the IDE subsystem.
Stop including internal.h there and use the appropriate new headers
ide-bus.h and ide-dma.h instead.

[PULL 25/25] hw/sparc/leon3: Fix wrong usage of DO_UPCAST macro

[Philippe Mathieu-Daudé]

From: Thomas Huth <thuth@redhat.com>

leon3.c currently fails to compile with some compilers when the -Wvla
option has been enabled:

 ../hw/sparc/leon3.c: In function ‘leon3_cpu_reset’:
 ../hw/sparc/leon3.c:153:5: error: ISO C90 forbids variable length array
  ‘offset_must_be_zero’ [-Werror=vla]
   153 |     ResetData *s = (ResetData *)DO_UPCAST(ResetData, info[id], info);
       |     ^~~~~~~~~
 cc1: all warnings being treated as errors

Looking at this code, the DO_UPCAST macro is indeed used in a wrong way
here: DO_UPCAST is supposed to check that the second parameter is the
first entry of the struct that the first parameter indicates, but since
we use and index into the info[] array, this of course cannot work.

The intention here was likely rather to use the container_of() macro
instead, so switch the code accordingly.

I did the mistake to rebase on master after testing,
and not test again, and missed a new header must be
added in "hw/i386/kvmvapic.c". I apologize for that
and will respin a v2 once fully tested again.

Regards,

Phil.
