      ccid: add ccid-card-emulated device · 585738a6
      由 Alon Levy 提交于 
      This devices uses libcacard (internal) to emulate a smartcard conforming
to the CAC standard. It attaches to the usb-ccid bus. Usage instructions
(example command lines) are in the following patch in docs/ccid.txt. It
uses libcacard which uses nss, so it can work with both hw cards and
certificates (files).

ccid-card-passthru: force chardev user wakeup by sending Init

The problem: how to wakeup the user of the smartcard when the smartcard
device is initialized?

Long term solution: have a callback interface. This was done via
the deprecated so called chardev ioctl interface.

Short term solution: do a write. Specifically we write an Init message.
And we change the client to send it's own Init message regardless of
receiving this one. Additional Init messages will be regarded as
acceptable, the first one received after connection establishment is
the determining one wrt capabilities.

      由 Alon Levy 提交于 
      A CCID device is a smart card reader. It is a USB device, defined at [1].
This patch introduces the usb-ccid device that is a ccid bus. Next patches will
introduce two card types to use it, a passthru card and an emulated card.

Comment for "return consistent self-powered state":

the Configuration Descriptor bmAttributes claims we are self powered,
but we were returning not self powered to USB_REQ_GET_STATUS control message.

In practice, this message is not sent by a linux 2.6.35.10-74.fc14.x86_64
guest (not tested on other guests), unless you issue lsusb -v as root (for
example).

      hw/versatilepb, realview: Fix condition for instantiation of onboard NIC · e6b3c8ca
      由 Peter Maydell 提交于 
      Correct the condition determining whether we instantiate the onboard
NIC or a PCI card NIC on VersatilePB and Realview boards. This was broken
in two ways:
 (1) if the user asked for two default NICs ("-net nic -net nic") we would
crash trying to strcmp() a NULL pointer
 (2) if the user asked for two NICs explicitly of the same model as the
onboard NIC (eg "-net nic,model=smc91c111 -net nic,model=smc91c111")
we would try to instantiate two onboard NICs at the same address.

      pcnet: Fix sign extension: make ipxe work with >2G RAM · 366c9332
      由 Michael Brown 提交于 
      The problem is with definitions in hw/pcnet.c such as:

  #define CSR_CRDA(S)      ((S)->csr[28] | ((S)->csr[29] << 16))

"(S)->csr[29]" is a uint16_t, but "(S)->csr[29] << 16" gets promoted to
int, so the overall CSR_CRDA(s) is a (signed) int rather than a uint32_t.

This then gets assigned to a uint64_t using

  target_phys_addr_t crda = CSR_CRDA(s);

so when (S)->csr[29] has the high bit set, we end up with
crda=0xffffffffxxxxxxxx.

      Add SLOF-based partition firmware for pSeries machine, allowing more boot options · a9f8ad8f
      由 David Gibson 提交于 
      Currently, the emulated pSeries machine requires the use of the
-kernel parameter in order to explicitly load a guest kernel.  This
means booting from the virtual disk, cdrom or network is not possible.

This patch addresses this limitation by inserting a within-partition
firmware image (derived from the "SLOF" free Open Firmware project).
If -kernel is not specified, qemu will now load the SLOF image, which
has access to the qemu boot device list through the device tree, and
can boot from any of the usual virtual devices.

In order to support the new firmware, an extension to the emulated
machine/hypervisor is necessary.  Unlike Linux, which expects
multi-CPU entry to be handled kexec() style, the SLOF firmware expects
only one CPU to be active at entry, and to use a hypervisor RTAS
method to enable the other CPUs one by one.

This patch also implements this 'start-cpu' method, so that SLOF can
start the secondary CPUs and marshal them into the kexec() holding
pattern ready for entry into the guest OS.  Linux should, and in the
future might directly use the start-cpu method to enable initially
disabled CPUs, but for now it does require kexec() entry.

      Implement PAPR VPA functions for pSeries shared processor partitions · ed120055
      由 David Gibson 提交于 
      Shared-processor partitions are those where a CPU is time-sliced between
partitions, rather than being permanently dedicated to a single
partition.  qemu emulated partitions, since they are just scheduled with
the qemu user process, behave mostly like shared processor partitions.

In order to better support shared processor partitions (splpar), PAPR
defines the "VPA" (Virtual Processor Area), a shared memory communication
channel between the hypervisor and partitions.  There are also two
additional shared memory communication areas for specialized purposes
associated with the VPA.

A VPA is not essential for operating an splpar, though it can be necessary
for obtaining accurate performance measurements in the presence of
runtime partition switching.

Most importantly, however, the VPA is a prerequisite for PAPR's H_CEDE,
hypercall, which allows a partition OS to give up it's shared processor
timeslices to other partitions when idle.

This patch implements the VPA and H_CEDE hypercalls in qemu.  We don't
implement any of the more advanced statistics which can be communicated
through the VPA.  However, this is enough to make normal pSeries kernels
do an effective power-save idle on an emulated pSeries, significantly
reducing the host load of a qemu emulated pSeries running an idle guest OS.

      Add a PAPR TCE-bypass mechanism for the pSeries machine · 08942ac1
      由 Ben Herrenschmidt 提交于 
      Usually, PAPR virtual IO devices use a virtual IOMMU mechanism, TCEs,
to mediate all DMA transfers.  While this is necessary for some sorts of
operation, it can be complex to program and slow for others.

This patch implements a mechanism for bypassing TCE translation, treating
"IO" addresses as plain (guest) physical memory addresses.  This has two
main uses:
 * Simple, but 64-bit aware programs like firmwares can use the VIO devices
without the complexity of TCE setup.
 * The guest OS can optionally use the TCE bypass to improve performance in
suitable situations.

The mechanism used is a per-device flag which disables TCE translation.
The flag is toggled with some (hypervisor-implemented) RTAS methods.
