2011-04-20hw/arm_boot.c: move initrd load address up to accommodate large kernelsPeter Maydell1-1/+1
Newer kernels are large enough that they can overlap the address where qemu places the initrd. Move the initrd up so that there is enough space for the kernel again. Unfortunately it's not possible to automatically determine the size of the kernel if it is compressed, so this is the best we can do.

2011-04-18s390x: virtio machine storage keysAlexander Graf1-12/+9
For emulation (and migration) we need to know about the guest's storage keys. These are separate from actual RAM contents, so we need to allocate them in parallel to RAM. While touching the file, this patch also adjusts the hypercall function to a new syntax that aligns better with tcg emulated code.

2011-04-15sparc: Fix assertion caused by empty memory slot with 0 byteStefan Weil1-9/+12
If the memory size given on the command line is equal to the maximum size of memory defined by the hardware, there is no "empty slot" after physical memory. The following command qemu-system-sparc -m 256 raised an assertion: exec.c:2614: cpu_register_physical_memory_offset: Assertion `size' failed This can be fixed either at the caller side (don't call empty_slot_init) or in empty_slot_init (do nothing) when size == 0.

2011-04-13atapi: GESN: implement 'media' subcommandAmit Shah2-4/+115
Implement the 'media' sub-command of the GET_EVENT_STATUS_NOTIFICATION command. This helps us report tray open, tray closed, no media, media present states to the guest. Newer Linux kernels (2.6.38+) rely on this command to revalidate discs after media change. This patch also sends out tray open/closed status to the guest driver when requested e.g. via the CDROM_DRIVE_STATUS ioctl (thanks Markus). Without such notification, the guest and qemu's tray open/close status was frequently out of sync, causing installers like Anaconda detecting no disc instead of tray open, confusing them terribly.

2011-04-08Delay creation of pseries device tree until resetDavid Gibson2-48/+75
At present, the 'pseries' machine creates a flattened device tree in the machine->init function to pass to either the guest kernel or to firmware. However, the machine->init function runs before processing of -device command line options, which means that the device tree so created will be (incorrectly) missing devices specified that way. Supplying a correct device tree is, in any case, part of the required platform entry conditions. Therefore, this patch moves the creation and loading of the device tree from machine->init to a reset callback. The setup of entry point address and initial register state moves with it, which leads to a slight cleanup. This is not, alas, quite enough to make a fully working reset for pseries. For that we would need to reload the firmware images, which on this machine are loaded into RAM. It's a step in the right direction, though.

2011-04-08pseries: Abolish envs arrayDavid Gibson3-38/+46
Currently the pseries machine init code builds up an array, envs, of CPUState pointers for all the cpus in the system. This is kind of pointless, given the generic code already has a perfectly good linked list of the cpus. In addition, there are a number of places which assume that the cpu's cpu_index field is equal to its index in this array. This is true in practice, because cpu_index values are just assigned sequentially, but it's conceptually incorrect and may not always be true. Therefore, this patch abolishes the envs array, and explicitly uses the generic cpu linked list and cpu_index values throughout.

2011-04-07virtio-balloon: fixed endianness bug in the config spaceAlexey Kardashevskiy1-1/+1
The specification for the virtio balloon device requres that the values in the config space be encoded little-endian. This differs from most virtio things, where guest-native endian is the norm. Currently, the qemu virtio-balloon code correctly makes the conversion on get_config(), but doesn't on set_config for the 'actual' field. The kernel driver, on the other hand, correctly converts when setting the actual field, but does not convert when reading the config space. The upshot is that virtio-balloon will only work correctly if both host and guest are LE, making all the conversions nops. This patch corrects the qemu side, correctly doing host-native <-> LE conversions when accessing the config space. This won't break any setups that aren't already broken, and fixes the case of BE host, LE guest. Fixing the BE guest case will require kernel fixes as well.

The 9p code already contains an attempt at the necessary endian conversions, but it's broken. The code which does conversion from host to guest does it correctly and this code was copied to the function which does guest to host conversion. However the copied code hasn't been correctly updated, so it first endian converts some garbage on the stack and then overwrites it with a field from incoming packet without conversion.
