2012-02-17i8254: Pass alternative IRQ output object on initializationJan Kiszka1-1/+1
HPET legacy emulation will require control over the PIT IRQ output. To enable this, add support for an alternative IRQ output object to the PIT factory function. If the isa_irq number is < 0, this object will be used. This also removes the IRQ number property from the PIT class as we now use a generic GPIO output pin that is connected by the factory function.

2012-01-04vmstate, memory: decouple vmstate from memory APIAvi Kivity1-2/+4
Currently creating a memory region automatically registers it for live migration. This differs from other state (which is enumerated in a VMStateDescription structure) and ties the live migration code into the memory core. Decouple the two by introducing a separate API, vmstate_register_ram(), for registering a RAM block for migration. Currently the same implementation is reused, but later it can be moved into a separate list, and registrations can be moved to VMStateDescription blocks. Signed-off-by: Avi Kivity <avi@redhat.com>

2011-09-04pflash_cfi01/pflash_cfi02: convert to memory APIAvi Kivity1-6/+7
cfi02 is annoying in that is ignores some address bits; we probably want explicit support in the memory API for that. In order to get the correct opaque into the MemoryRegion object, the allocation scheme is changed so that the flash emulation code allocates memory, instead of the caller. This clears a FIXME in the flash code. Signed-off-by: Avi Kivity <avi@redhat.com>

2010-12-11isa_mmio: Always use little endianAlexander Graf1-5/+1
This patch converts the ISA MMIO bridge code to always use little endian mmio. All bswap code that existed was only there to convert from native cpu endianness to little endian ISA devices. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-12-11Add endianness as io mem parameterAlexander Graf1-1/+2
As stated before, devices can be little, big or native endian. The target endianness is not of their concern, so we need to push things down a level. This patch adds a parameter to cpu_register_io_memory that allows a device to choose its endianness. For now, all devices simply choose native endian, because that's the same behavior as before.

2010-06-13hpet/rtc: Rework RTC IRQ replacement by HPETJan Kiszka1-1/+1
Allow the intercept the RTC IRQ for the HPET legacy mode. Then push routing to IRQ8 completely into the HPET. This allows to turn hpet_in_legacy_mode() into a private function. Furthermore, this stops the RTC from clearing IRQ8 even if the HPET is in control. This patch comes with a side effect: The RTC timers will no longer be stoppend when there is no IRQ consumer, possibly causing a minor performance degration. But as the guest may want to redirect the RTC to the SCI in that mode, it should normally disable unused IRQ source anyway.

2010-03-16load_elf: replace the address addend by a translation functionAurelien Jarno1-10/+7
A few machines need to translate the ELF header addresses into physical addresses. Currently the only possibility is to add a value to the addresses. This patch replaces the addend argument by and a translation function and an opaque passed to the function. A NULL function does not translate the address. The patch also convert all machines that have an addend, simplify the PowerPC kernel loading and fix the MIPS kernel loading using this new feature. Other machines may benefit from this feature.

2009-10-12rom loader: fix sparc -kernel boot.Gerd Hoffmann1-1/+1
Changes: (1) register pstrcpy_targphys() in rom list, it is used for kernel command lines by a number of architectures. (2) add rom_ptr() function to get a pointer for applying changes to loaded images. Needed for example to tell the linux kernel where it finds the initrd image by updating the header. (3) make sparc use rom_ptr for initrd setup. booting sparc-test works now, and 'info roms' shows this: (qemu) info roms addr=0000000000000000 size=0x2a3828 mem=ram name="phdr #0: vmlinux-2.6.11+tcx" addr=00000000007ff000 size=0x00000e mem=ram name="cmdline" addr=0000000000800000 size=0x400000 mem=ram name="/root/qemu-test/sparc-test/linux.img" addr=0000000070000000 size=0x0e4000 mem=rom name="phdr #0: /home/kraxel/projects/qemu/build-zfull/pc-bios/openbios-sparc32" reboot via 'system_reset' works too.

2009-05-22Introduce reset notifier orderJan Kiszka1-1/+1
Add the parameter 'order' to qemu_register_reset and sort callbacks on registration. On system reset, callbacks with lower order will be invoked before those with higher order. Update all existing users to the standard order 0. Note: At least for x86, the existing users seem to assume that handlers are called in their registration order. Therefore, the patch preserves this property. If someone feels bored, (s)he could try to identify this dependency and express it properly on callback registration.
