* arm: boot: Support big-endian elfsPeter Crosthwaite2016-03-041-0/+9
| | | | | | | | | | | | | | | Support ARM big-endian ELF files in system-mode emulation. When loading an elf, determine the endianness mode expected by the elf, and set the relevant CPU state accordingly. With this, big-endian modes are now fully supported via system-mode LE, so there is no need to restrict the elf loading to the TARGET endianness so the ifdeffery on TARGET_WORDS_BIGENDIAN goes away.

* loader: Add data swap option to load-elfPeter Crosthwaite2016-03-042-2/+25
| | | | | | | | | | | | | | | | | | | | | | | Some CPUs are of an opposite data-endianness to other components in the system. Sometimes elfs have the data sections layed out with this CPU data-endianness accounting for when loaded via the CPU, so byte swaps (relative to other system components) will occur. The leading example, is ARM's BE32 mode, which is is basically LE with address manipulation on half-word and byte accesses to access the hw/byte reversed address. This means that word data is invariant across LE and BE32. This also means that instructions are still LE. The expectation is that the elf will be loaded via the CPU in this endianness scheme, which means the data in the elf is reversed at compile time. As QEMU loads via the system memory directly, rather than the CPU, we need a mechanism to reverse elf data endianness to implement this possibility.

| | | | | | | | | | | | | | | | Add a new function load_image_mr(), which behaves like load_image_targphys() except that it loads the ROM image to a specified MemoryRegion rather than to a specified physical address. This is useful when a ROM blob needs to be loaded to a particular flash or ROM device but the address of that device in the machine's address space is not known. (For instance, ROMs in devices, or ROMs which might exist in a different address space to the system address space.)

* rng: add request queue support to rng-randomLadi Prosek2016-03-031-2/+1Star
| | | | | | | | | | | | | | | | | | | | Requests are now created in the RngBackend parent class and the code path is shared by both rng-egd and rng-random. This commit fixes the rng-random implementation which processed only one request at a time and simply discarded all but the most recent one. In the guest this manifested as delayed completion of reads from virtio-rng, i.e. a read was completed only after another read was issued. By switching rng-random to use the same request queue as rng-egd, the unsafe stack-based allocation of the entropy buffer is eliminated and replaced with g_malloc.

The return value of these functions is a valid IRQ number if errp is NULL. It is undefined otherwise. The corresponding error traces get promotted to error messages. Note that the "can't allocate IRQ" error message in spapr_vio_busdev_realize() also moves to xics_alloc(). Similar error message consolidation isn't really applicable to xics_alloc_block() because callers have extra context (device config address, MSI or MSIX). This fixes the issues mentioned above.

| * | virtio-blk: fix "disabled data plane" modePaolo Bonzini2016-02-251-0/+1

This patch simplifies a bit the handling of disabled mode. In disabled mode, virtio_blk_handle_output might be called even if s->dataplane is not NULL. This is a bit tricky, because the current check for s->dataplane will always trigger, causing a continuous stream of calls to virtio_blk_data_plane_start. Unfortunately, these calls will not do anything. To fix this, set the "started" flag even in disabled mode, and skip virtio_blk_data_plane_start if the started flag is true. The resulting changes also prepare the code for the next patch, were virtio-blk dataplane will reuse the same virtio_blk_handle_output function as "regular" virtio-blk. Because struct VirtIOBlockDataPlane is opaque in virtio-blk.c, we have to move s->dataplane->started inside struct VirtIOBlock.
