* isa_mmio: Always use little endianAlexander Graf2010-12-111-1/+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.

* PPC: Add PV hypercall transport through fw_cfgAlexander Graf2010-08-261-0/+7
| | | | | | | | | | | On KVM for PPC we need to tell the guest which instructions to use when doing a hypercall. The clean way to do this is to go through an ioctl from userspace and passing it on to the guest using the device tree. So let's do the qemu part here: read out the hypercall and pass it on to the guest's fw_cfg so openBIOS can read it out and expose it again. Signed-off-by: Alexander Graf <agraf@suse.de>
* Rearrange block headersBlue Swirl2010-08-241-0/+1
| | | | | | | | | Changing block.h or blockdev.h resulted in recompiling most objects. Move DriveInfo typedef and BlockInterfaceType enum definitions to qemu-common.h and rearrange blockdev.h use to decrease churn. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
* qemu_ram_alloc: Add DeviceState and name parametersAlex Williamson2010-07-061-3/+3
| | | | | | | | | | | These will be used to generate unique id strings for ramblocks. The name field is required, the device pointer is optional as most callers don't have a device. When there's no device or the device isn't a child of a bus implementing BusInfo.get_dev_path, the name should be unique for the platform.

| | | | | | | This reverts commit f1698408f1dcb7548a21828a0b1e2b530fae3af3. PCI is always little-endian. Having a user-visible "be" property is just plain wrong.

* load_elf: replace the address addend by a translation functionAurelien Jarno2010-03-161-11/+10
| | | | | | | | | | | | | | | | 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.

* KVM: Rework VCPU state writeback APIJan Kiszka2010-03-041-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This grand cleanup drops all reset and vmsave/load related synchronization points in favor of four(!) generic hooks: - cpu_synchronize_all_states in qemu_savevm_state_complete (initial sync from kernel before vmsave) - cpu_synchronize_all_post_init in qemu_loadvm_state (writeback after vmload) - cpu_synchronize_all_post_init in main after machine init - cpu_synchronize_all_post_reset in qemu_system_reset (writeback after system reset) These writeback points + the existing one of VCPU exec after cpu_synchronize_state map on three levels of writeback: - KVM_PUT_RUNTIME_STATE (during runtime, other VCPUs continue to run) - KVM_PUT_RESET_STATE (on synchronous system reset, all VCPUs stopped) - KVM_PUT_FULL_STATE (on init or vmload, all VCPUs stopped as well) This level is passed to the arch-specific VCPU state writing function that will decide which concrete substates need to be written. That way, no writer of load, save or reset functions that interact with in-kernel KVM states will ever have to worry about synchronization again. That also means that a lot of reasons for races, segfaults and deadlocks are eliminated. cpu_synchronize_state remains untouched, just as Anthony suggested. We continue to need it before reading or writing of VCPU states that are also tracked by in-kernel KVM subsystems. Consequently, this patch removes many cpu_synchronize_state calls that are now redundant, just like remaining explicit register syncs.

* PPC: tell the guest about the time base frequencyAlexander Graf2010-02-141-0/+9
| | | | | | | | | | | | | | | | | | | | | Our guest systems need to know by how much the timebase increases every second, so there usually is a "timebase-frequency" property in the cpu leaf of the device tree. This property is missing in OpenBIOS. With qemu, Linux's fallback timebase speed and qemu's internal timebase speed match up. With KVM, that is no longer true. The guest is running at the same timebase speed as the host. This leads to massive timing problems. On my test machine, a "sleep 2" takes about 14 seconds with KVM enabled. This patch exports the timebase frequency to OpenBIOS, so it can then put them into the device tree. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

| | | | | | | | | | | Some recent change made PPC guests always start at address 0x0 because env isn't synced to kvm_state on first bootup.

* rom loader: fix sparc -kernel boot.Gerd Hoffmann2009-10-121-1/+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.

* Fix pci_add nic not to exit on bad modelMarkus Armbruster2009-10-051-1/+1
| | | | | | | | | | | | | | | | Monitor command "pci_add ADDR nic model=MODEL" uses pci_nic_init() to create the NIC. When MODEL is unknown or "?", this prints to stderr and terminates the program. Change pci_nic_init() not to treat "?" specially, and to return NULL on failure. Switch uses during startup to new convenience wrapper pci_nic_init_nofail(), which behaves just like pci_nic_init() used to do. Bonus bug fix: we now check for qdev_init() failing there.

* Support addr=... in option argument of -net nicMarkus Armbruster2009-06-221-1/+1
| | | | | | | | | | | | | | | | | Make net_client_init() accept addr=, put the value into struct NICinfo. Use it in pci_nic_init(), and remove arguments bus and devfn. Don't support addr= in third argument of monitor command pci_add, because that clashes with its first argument. Admittedly unelegant. Machines "malta" and "r2d" have a default NIC with a well-known PCI address. Deal with that the same way as the NIC model: make pci_nic_init() take an optional default to be used when the user doesn't specify one.

* Introduce reset notifier orderJan Kiszka2009-05-221-1/+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.
