2025-07-15qemu: Declare all load/store helper in 'qemu/bswap.h'Philippe Mathieu-Daudé1-1/+0
Restrict "exec/tswap.h" to the tswap*() methods, move the load/store helpers with the other ones declared in "qemu/bswap.h".

2025-02-16hw/arm: Mark Allwinner Technology devices as little-endianPhilippe Mathieu-Daudé1-1/+1
These devices are only used by the ARM targets, which are only built as little-endian. Therefore the DEVICE_NATIVE_ENDIAN definition expand to DEVICE_LITTLE_ENDIAN (besides, the DEVICE_BIG_ENDIAN case isn't tested). Simplify directly using DEVICE_LITTLE_ENDIAN.

Headers in include/sysemu/ are not only related to system *emulation*, they are also used by virtualization. Rename as system/ which is clearer.

2024-10-21replace error_setg(&error_fatal, ...) with error_report()Tudor Gheorghiu1-3/+2
According to include/qapi/error.h: * Please don't error_setg(&error_fatal, ...), use error_report() and * exit(), because that's more obvious. Patch updates all instances of error_setg(&error_fatal, ...) with error_report(...), adds the explicit exit(1) and removes redundant return statements.

2024-10-03hw/char: Extract serial-mmBernhard Beschow1-1/+1
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>

2024-01-26target/arm: Move ARM_CPU_IRQ/FIQ definitions to 'cpu-qom.h' headerPhilippe Mathieu-Daudé1-0/+1
The ARM_CPU_IRQ/FIQ definitions are used to index the GPIO IRQ created calling qdev_init_gpio_in() in ARMCPU instance_init() handler. To allow non-ARM code to raise interrupt on ARM cores, move they to 'target/arm/cpu-qom.h' which is non-ARM specific and can be included by any hw/ file.
