      Rename target_phys_addr_t to hwaddr · a8170e5e
      由 Avi Kivity 提交于 
      target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific).  Replace it with a finger-friendly,
standards conformant hwaddr.

Outstanding patchsets can be fixed up with the command

  git rebase -i --exec 'find -name "*.[ch]"
                        | xargs s/target_phys_addr_t/hwaddr/g' origin

      s390x: implement SIGP restart and shutdown · 1864b94a
      由 Alexander Graf 提交于 
      An s390x OS does reboot and shutdown triggers through hypercalls that
we didn't implement on the TCG backend yet. That means that so far we
couldn't shut down virtual machines for example, having them hang on
shutdown when not using KVM.

With this patch, this restriction is gone. We can now shut down and
reboot s390x virtual machines even when using the TCG backend.

      s390x: implement rrbe instruction properly · 17bb18ce
      由 Alexander Graf 提交于 
      The rrbe instruction resets the reference bit in the given storage key.
So far, we merely made it a nop and also returned an invalid CC value,
so that the kernel never knew if a page actually got accessed.

This patch implements it properly, flushing the R bit and returning the
correct CC value.

      s390x: update R and C bits in storage key · b9959138
      由 Alexander Graf 提交于 
      When the s390x maps a page or writes happen to a page, the R and C
bits get updated. The easiest way to implement this in qemu is to
simply update them whenever we map a TLB translation and act according
to the permissions.

      s390x: make ipte 31-bit aware · 09ed75f7
      由 Alexander Graf 提交于 
      When running 31-bit code we can potentially map the same virtual
address twice - once as 0x0yyyyyyy and once as 0x8yyyyyyy, because
the upper bit gets ignored.

This also should be reflected in the tlb invalidation path, so we
really invalidate also the transparently created tlb entries.

      exec.h cleanup · 3e457172
      由 Blue Swirl 提交于 
      Move softmmu_exec.h include directives from target-*/exec.h to
target-*/op_helper.c. Move also various other stuff only used in
op_helper.c there.

Define global env in dyngen-exec.h.

For i386, move wrappers for segment and FPU helpers from user-exec.c
to op_helper.c. Implement raise_exception_err_env() to handle dynamic
CPUState. Move the function declarations to cpu.h since they can be
used outside of op_helper.c context.

LM32, s390x, UniCore32: remove unused cpu_halted(), regs_to_env() and
env_to_regs().

ARM: make raise_exception() static.

Convert
#include "exec.h"
to
#include "cpu.h"
#include "dyngen-exec.h"
and remove now unused target-*/exec.h.

      Switch build system to accompanied kernel headers · e205c790
      由 Jan Kiszka 提交于 
      This helps reducing our build-time checks for feature support in the
available Linux kernel headers. And it helps users that do not have
sufficiently recent headers installed on their build machine.

Consequently, the patch removes and build-time checks for kvm and vhost
in configure, the --kerneldir switch, and KVM_CFLAGS. Kernel headers are
supposed to be provided by QEMU only.

s390 needs some extra love as it carries redefinitions from kernel
headers.

      s390x: fix cksm instruction · 5b185639
      由 Alexander Graf 提交于 
      The cksm instruction was implemented incorrectly, rendering UDP and TCP
checksum calculation wrong, making an emulated s390x Linux guest break
in most networking operations.

This patch fixes odd end checksum calculation, takes the input register
as input for the checksum and optimizes the overflow pieces by a bit.
