2010-12-11isa_mmio: Always use little endianAlexander Graf1-1/+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. 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.

2010-09-18Check for errors during BIOS or kernel loadBlue Swirl1-1/+2
Because of the use of unsigned types, possible errors during BIOS or kernel load were ignored. Fix by using a signed type. This also avoids some warnings with GCC flag -Wtype-limits. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-08-26PPC: Add PV hypercall transport through fw_cfgAlexander Graf1-0/+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>
2010-08-24Rearrange block headersBlue Swirl1-0/+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>
2010-07-06qemu_ram_alloc: Add DeviceState and name parametersAlex Williamson1-3/+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.

2010-03-16load_elf: replace the address addend by a translation functionAurelien Jarno1-10/+9
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.

2010-03-04KVM: Rework VCPU state writeback APIJan Kiszka1-3/+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.

2010-02-14PPC: Add USB per default on U3Alexander Graf1-1/+11
Linux with CONFIG_PPC64 doesn't support ADB devices anymore, so we have to use USB for keyboard and mouse. This patch enables USB per default on U3 and adds a virtual keyboard and mouse there. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-02-14PPC: Use macio IDE controller for NewworldAlexander Graf1-5/+11
Per default Linux doesn't come with a lot of storage adapters enabled on Mac configurations. The one that's pretty much always present is the pmac-ide, while the cmd64x is almost never included in any distribution. So let's switch to use the MacIO based IDE controller. There is corresponding OpenBIOS code to get interrupts working properly. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-02-14PPC: tell the guest about the time base frequencyAlexander Graf1-0/+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>
2010-02-14PPC: Include dump of lspci -nn on real G5Alexander Graf1-0/+24
To ease debugging and to know what we're lacking, I found it really useful to have an lspci dump of a real U3 based G5 around. So I added a comment for it. If people don't think it's important enough to include this information in the sources, just don't apply this patch. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-02-14PPC: Use Mac99_U3 type on ppc64Alexander Graf1-2/+10
The "Mac99" type so far defines a "U2" based configuration. Unfortunately, there have never been any U2 based PPC64 machines. That's what the U3 was developed for. So let's split the Mac99 machine in a PPC64 and a PPC32 machine. The PPC32 machine stays "Mac99", while the PPC64 one becomes "Mac99_U3". All peripherals stay the same.

2009-12-19target-ppc: Use interrupts for esccAlexander Graf1-5/+1
When using the escc with Linux, we need interrupts. So instead of creating a dummy device, let's just map them to the openpic we have anyways. This makes Linux on PPC64 with console=ttyPZ0 work. Obviously, this change needs to be reflected in openbios. Patch for that follows this one. Please update the binary then.

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.

2009-10-05Fix pci_add nic not to exit on bad modelMarkus Armbruster1-1/+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.

You can add a OHCI USB Controller to your virtual pc now using '-device pci-ohci'.

2009-06-22Support addr=... in option argument of -net nicMarkus Armbruster1-1/+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.

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.
