One strategy to limit the startup delay of consistency check when opening image files is to ensure that the file is marked dirty for as little time as possible. QED currently marks the image dirty when the first allocating write request is issued and clears the dirty bit again when the image is cleanly closed. In practice that means the image is marked dirty for most of a guest's lifetime and prone to being in a dirty state upon crash or power failure. It is safe to clear the dirty bit after all allocating write requests have completed and a flush has been performed. This patch adds a timer after the last allocating write request completes. When the timer fires it will flush and then clear the dirty bit. The timer is set to 5 seconds and is cancelled upon arrival of a new allocating write request.

On IA32 host or IA32 PAE host, at present, generally, we can't create an HVM guest with more than 2G memory, because generally it's almost impossible for Qemu to find a large enough and consecutive virtual address space to map an HVM guest's whole physical address space. The attached patch fixes this issue using dynamic mapping based on little blocks of memory. Each call to qemu_get_ram_ptr makes a call to qemu_map_cache with the lock option, so mapcache will not unmap these ram_ptr. Blocks that do not belong to the RAM, but usually to a device ROM or to a framebuffer, are handled in a separate function. So the whole RAMBlock can be map.

Trace events cannot use %s in their format strings because trace backends vary in how they can deference pointers (if at all). Recording const char * values is not meaningful if their contents are not recorded too. Change grlib trace events that rely on strings so that they communicate similar information without using strings. A follow-up patch explains this limitation and updates docs/tracing.txt.

This patch adds support for Milkymist's SoftUSB core. This model differ from the real hardware in its functionality.

This patch adds support for the Milkymist's High Performance Dynamic Memory Controller. This is just a dumb model without any functionality.

This patch add support for a system control block. It is supposed to act as helper for the emulated program. E.g. shutting down the VM or printing test results. This model is intended for testing purposes only and doesn't fit to any real hardware. Therefore, it is not added to any board by default.

This patch adds fields to the USBDevice struct for the current speed (hard-wired to full speed for now) and current device configuration. Also a init function is added which inializes these fields. This allows USB_REQ_{GET,SET}_CONFIGURATION handling to be moved to common code. For most drivers the conversion is trivial ad they support a single configuration only anyway. One exception is bluetooth where some device-specific setup code runs after get/set configuration. The other is usb-net which actually has two configurations so the the code to check for the active configuration has been adapted. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

This patch adds hw/usb-desc.[ch] files. They carry data structures for various usb descriptors and helper functions to generate usb packets from the structures. The intention is to have a internal representation of the device desription which is more usable than the current char array blobs, so we can have common code handle common usb device emulation using the device description. The usage of this infrastructure is optional for usb drivers as there are cases such as pass-through where it probably isn't very useful. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

This patch implements the read/write state machine. Operations are fully asynchronous and multiple operations may be active at any time. Allocating writes lock tables to ensure metadata updates do not interfere with each other. If two allocating writes need to update the same L2 table they will run sequentially. If two allocating writes need to update different L2 tables they will run in parallel. Signed-off-by: NStefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

This patch adds code to look up data cluster offsets in the image via the L1/L2 tables. The L2 tables are writethrough cached in memory for performance (each read/write requires a lookup so it is essential to cache the tables). With cluster lookup code in place it is possible to implement bdrv_is_allocated() to query the number of contiguous allocated/unallocated clusters.
