Change much of hw/pci to use symbolic constants and a table-driven design: add a mask table with writable bits set and readonly bits unset. Detect change by comparing original and new registers. This makes it easy to support capabilities where read-only/writeable bit layout differs between devices, depending on capabilities present. As a result, writing a single byte in BAR registers now works as it should. Writing to upper limit registers in the bridge also works as it should. Code is also shorter. Signed-off-by: NMichael S.

Microblaze recently changed their ABI. The new is not backwards compatible and there doesn't seem to be a way to distinguish old/new binaries. Let's support the latest ABI for now and hope someone figures out a way to hande both ABI's later. Signed-off-by: NEdgar E. Iglesias <edgar.iglesias@gmail.com>

Access to the PVR SPR is normally forbidden from userspace apps. The Linux kernel, however, fixes up reads in the appropriate trap handler. To permit applications that read PVR to run on QEMU, then, we need to implement the same handling of PVR reads.

`sdl-config --cflags` defines main = SDL_main on some platforms. One of these platforms is Windows with mingw32. For those platforms, the solution already developed for __APPLE__ is now applied. A compiler warning (missing return value) is fixed, too. Maybe __APPLE__ no longer needs a separate check.

2.6.30 adds a new TUNSETSNDBUF ioctl() which allows a send buffer limit for the tap device to be specified. When this limit is reached, a tap write() will return EAGAIN and poll() will indicate the fd isn't writable. This allows people to tune their setups so as to avoid e.g. UDP packet loss when the sending application in the guest out-runs the NIC in the host. There is no obviously sensible default setting - a suitable value depends mostly on the capabilities of the physical NIC through which the packets are being sent. Also, note that when using a bridge with netfilter enabled, we currently never get EAGAIN because netfilter causes the packet to be immediately orphaned. Set /proc/sys/net/bridge/bridge nf-call-iptables to zero to disable this behaviour. Signed-off-by: NMark McLoughlin <markmc@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

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.

This should fix compilation problem in case of CONFIG_USER_ONLY. Currently INIT/SIPI is handled in the context of CPU that sends IPI. This patch changes this to handle them like all other events in a main cpu exec loop. When KVM will gain thread per vcpu capability it will be much more clear to handle those event by cpu thread itself and not modify one cpu's state from the context of the other.

Support a new feature flag for indirect ring entries. These are ring entries which point to a table of buffer descriptors. The idea here is to increase the ring capacity by allowing a larger effective ring size whereby the ring size dictates the number of requests that may be outstanding, rather than the size of those requests. This should be most effective in the case of block I/O where we can potentially benefit by concurrently dispatching a large number of large requests. Even in the simple case of single segment block requests, this results in a threefold increase in ring capacity.

The code how it is today, is totally painful to read and keep. To begin with, the code is duplicated with the option rom loading code that linux_boot and vga are already using. This patch introduces a "bootable" state in NICInfo structure, that we can use to keep track of whether or not a given nic should be bootable, avoiding the introduction of yet another global state. With that in hands, we move the code in vl.c to hw/pc.c, and use the already existing infra structure to load those option roms.
