7da845b0f4 target-arm: A64: Make cache ID registers visible to AArch64
Make the cache ID system registers (CLIDR, CSSELR, CCSIDR, CTR)
visible to AArch64. These are mostly simple 64-bit extensions of the
existing 32 bit system registers and so can share reginfo definitions.
CTR needs to have a split definition, but we can clean up the
temporary user-mode implementation in favour of using the CPU-specified
reset value, and implement the system-mode-required semantics of
restricting its EL0 accessibility if SCTLR.UCT is not set.

67ed771ded target-arm: Fix raw read and write functions on AArch64 registers
The raw read and write functions were using the ARM_CP_64BIT flag in
ri->type to determine whether to treat the register's state field as
uint32_t or uint64_t; however AArch64 register info structs don't use
that flag. Abstract out the "how big is the field?" test into a
function and fix it to work for AArch64 registers. For this to work
we must ensure that the reginfo structs put into the hashtable have
the correct state field for their use, not the placeholder STATE_BOTH.

855011be05 hw: arm_gic_kvm: Add KVM VGIC save/restore logic
Save and restore the ARM KVM VGIC state from the kernel.  We rely on
QEMU to marshal the GICState data structure and therefore simply
synchronize the kernel state with the QEMU emulated state in both
directions.

We take some care on the restore path to check the VGIC has been
configured with enough IRQs and CPU interfaces that we can properly
restore the state, and for separate set/clear registers we first fully
clear the registers and then set the required bits.

1da41cc1c6 arm: vgic device control api support
Support creating the ARM vgic device through the device control API and
setting the base address for the distributor and cpu interfaces in KVM
VMs using this API.

Because the older KVM_CREATE_IRQCHIP interface needs the irq chip to be
created prior to creating the VCPUs, we first test if we can use the
device control API in kvm_arch_irqchip_create (using the test flag from
the device control API).  If we cannot, it means we have to fall back to
KVM_CREATE_IRQCHIP and use the older ioctl at this point in time.  If
however, we can use the device control API, we don't do anything and
wait until the arm_gic_kvm driver initializes and let that use the
device control API.

Introduces two simple functions:
    int kvm_device_ioctl(int fd, int type, ...);
    int kvm_create_device(KVMState *s, uint64_t type, bool test);

These functions wrap the basic ioctl-based interactions with KVM in a
way similar to other KVM ioctl wrappers.

c10f7fc3d1 target-arm: Load correct access bits from ARMv5 level 2 page table descriptors
In ARMv5 level 2 page table descriptors, each 4K or 64K page is split into
four subpages, each of which can have different access permission settings,
which are specified by four two-bit fields in the l2 descriptor. A
long-standing cut-and-paste error meant we were using the wrong bits in
the virtual address to select the access-permission field for 4K pages.

The error has presumably not been noticed before because most guests don't
make use of the ability to set the access permissions differently for
each 1K subpage: if the guest gives the whole page the same access
permissions it doesn't matter which of the 4 AP fields we select.
(The whole issue is irrelevant for ARMv7 CPUs anyway because subpages
aren't supported there.)

d6085e3ace net: remove implicit peer from offload API
The virtio_net offload APIs are used on the NIC's peer (i.e. the tap
device).  The API was defined to implicitly use nc->peer, saving the
caller the trouble.

This wasn't ideal because:
1. There are callers who have the peer but not the NIC.  Currently they
   are forced to bypass the API and access peer->info->... directly.
2. The rest of the net.h API uses nc, not nc->peer, so it is
   inconsistent.

This patch pushes nc->peer back up to callers.

aded6539d9 qemu_file: use fwrite() correctly
fwrite() returns the number of items written.  But when there is one
error, it can return a short write.

In the particular bug that I was tracking, I did a migration to a
read-only filesystem.  And it was able to finish the migration
correctly.  fwrite() never returned a negative error code, nor zero,
always 4096. (migration writes chunks of about 14000 bytes).  And it
was able to "complete" the migration with success (yes, reading the
file was a bit more difficult).

To add insult to injury, if your amount of memory was big enough (12GB
on my case), it overwrote some important structure, and from them,
malloc failed.  This check makes the problem go away.

0a985b3727 net: Disable netmap backend when not supported
This patch fixes configure so that the netmap backend is not compiled in if the
host doesn't support an API version >= 11. A version upper bound (15) has been
added so that the netmap API can be extended with some minor features without
requiring QEMU code modifications.

Moreover, some changes have been done to net/netmap.c in order to reflect the
current netmap API/ABI (11).

The NETMAP_WITH_LIBS macro makes possible to include some utilities (e.g.
netmap ring macros, D(), RD() and other high level functions) through the netmap
headers. In this way we get rid of the D and RD macro definitions in the QEMU
code, and we open the way for further code simplifications that will be
introduced by future patches.

f6c65bfb93 net: add offloading support to netmap backend
Whit this patch, the netmap backend supports TSO/UFO/CSUM
offloadings, and accepts the virtio-net header, similarly to what
happens with TAP. The offloading callbacks in the NetClientInfo
interface have been implemented.

cf528b8958 net: virtio-net and vmxnet3 use offloading API
With this patch, virtio-net and vmxnet3 frontends make
use of the qemu_peer_* API for backend offloadings manipulations,
instead of calling TAP-specific functions directly.
We also remove the existing checks which prevent those frontends
from using offloadings with backends different from TAP (e.g. netmap).

6e50d18847 opencores_eth: flush queue whenever can_receive can go from false to true
The following registers control whether MAC can receive frames:
- MODER.RXEN bit that enables/disables receiver;
- TX_BD_NUM register that specifies number of RX descriptors.
Notify QEMU networking core when the MAC is ready to receive frames.
Discard frame and raise BUSY interrupt when the frame arrives but the
current RX descriptor is not empty.

98b21dcdb3 configure: check that C++ compiler actually works
Check that the C++ compiler works with the C compiler; if it
does not, then don't pass CXX to the build process. This
fixes a regression where QEMU was no longer building if the
build environment didn't have a C++ compiler (introduced
in commit 3144f78b, which incorrectly assumed that rules.mak
would only see a non-empty $(CXX) if configure had actually
found a working C++ compiler).
