2025-02-04hw/hppa: Wire up Diva GSP cardHelge Deller2-20/+12
Until now we used a standard serial-pci device to emulate a HP serial console. This worked nicely with 32-bit Linux and 32-bit HP-UX, but 64-bit HP-UX crashes with it and expects either a Diva GSP card, or a real 64-bit capable PCI graphic card (which we don't have yet). In order to continue with 64-bit HP-UX, switch over to the recently added Diva GSP card emulation. Signed-off-by: Helge Deller <deller@gmx.de>

2024-10-03hw/char: Extract serial-mmBernhard Beschow2-2/+2
hw/char/serial currently contains the implementation of both TYPE_SERIAL and TYPE_SERIAL_MM. According to serial_class_init(), TYPE_SERIAL is an internal class while TYPE_SERIAL_MM is used by numerous machine types directly. Let's move the latter into its own module which makes the dependencies more obvious and the code more tidy. The includes and the dependencies have been converted mechanically except in the hw/char directories which were updated manually. The result was compile-tested. Now, only hw/char makes direct use of TYPE_SERIAL: # grep -r -e "select SERIAL" | grep -v SERIAL_ hw/char/Kconfig: select SERIAL hw/char/Kconfig: select SERIAL hw/char/Kconfig: select SERIAL hw/char/Kconfig: select SERIAL hw/char/Kconfig: select SERIAL # grep -r -e "/serial\\.h" include/hw/char/serial-mm.h:#include "hw/char/serial.h" hw/char/serial-pci-multi.c:#include "hw/char/serial.h" hw/char/serial.c:#include "hw/char/serial.h" hw/char/serial-isa.c:#include "hw/char/serial.h" hw/char/serial-pci.c:#include "hw/char/serial.h" Tested-by: Andrew Jeffery <andrew@codeconstruct.com.au> Reviewed-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Signed-off-by: Bernhard Beschow <shentey@gmail.com> Link: https://lore.kernel.org/r/20240905073832.16222-4-shentey@gmail.com Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2024-09-24reset: Use ResetType for qemu_devices_reset() and MachineClass::reset()Juraj Marcin1-2/+2
Currently, both qemu_devices_reset() and MachineClass::reset() use ShutdownCause for the reason of the reset. However, the Resettable interface uses ResetState, so ShutdownCause needs to be translated to ResetType somewhere. Translating it qemu_devices_reset() makes adding new reset types harder, as they cannot always be matched to a single ShutdownCause here, and devices may need to check the ResetType to determine what to reset and if to reset at all. This patch moves this translation up in the call stack to qemu_system_reset() and updates all MachineClass children to use the ResetType instead.

2024-05-08hw/hppa/machine: Replace g_memdup() by g_memdup2()Philippe Mathieu-Daudé1-8/+8
Per https://discourse.gnome.org/t/port-your-module-from-g-memdup-to-g-memdup2-now/5538 The old API took the size of the memory to duplicate as a guint, whereas most memory functions take memory sizes as a gsize. This made it easy to accidentally pass a gsize to g_memdup(). For large values, that would lead to a silent truncation of the size from 64 to 32 bits, and result in a heap area being returned which is significantly smaller than what the caller expects. This can likely be exploited in various modules to cause a heap buffer overflow. Replace g_memdup() by the safer g_memdup2() wrapper. Trivially safe because the argument was directly from sizeof.

This will enable us to later support more than 4GB of RAM and is required that the OS (or PALO bootloader) will start or install a 64-bit kernel instead of a 32-bit kernel. Note that SeaBIOS-hppa v16 provides the "-fw_cfg opt/OS64,string=3" option with which the user can control what the firmware shall report back to the OS: Support of 32-bit OS, support of a 64-bit OS, or support for both (default).

The lasi_82596 support has been disabled since it was first introduced, since enable_lasi_lan() has always been zero. This allows the user to enable it by explicitly requesting a NIC model 'lasi_82596' or just using the alias 'lasi'. Otherwise, it defaults to a PCI NIC as before.

NetBSD even crashes, because it fails to map that page and then accesses unmapped memory.

Now that the lasips2 migration state is registered through the DeviceClass vmsd field, the base property and also the lasips2_properties array can be removed completely as they are no longer required.
