      target-cris: update CPU state save/load to use VMStateDescription · 16a1b6e9
      由 Juan Quintela 提交于 
      Update the CRIS CPU state save/load to use a VMStateDescription struct
rather than cpu_save/cpu_load functions.

Have to define TLBSet struct.
Multidimensional arrays in C are a mess, just unroll them.

[PMM:
 * expand commit message a little since it's no longer one patch in
   a 35-patch series
 * add header/copyright comment to machine.c; credited copyright is
   Red Hat and author is Juan, since this commit gives the file all-new
   contents; license is LGPL-2-or-later, to match other target-cris code
 * remove hardcoded tab
 * add fields for locked_irq, interrupt_vector, fault_vector, trap_vector
 * drop minimum_version_id_old fields
 * bump version_id to 2 as we are not compatible with old state format
 * remove unnecessary hw/boards.h include
 * update to register via dc->vmsd]

      disas: Remove uses of CPU env · d49190c4
      由 Peter Crosthwaite 提交于 
      disas does not need to access the CPU env for any reason. Change the
APIs to accept CPU pointers instead. Small change pattern needs to be
applied to all target translate.c. This brings us closer to making
disas.o a common-obj and less architecture specific in general.

      tcg: Change translator-side labels to a pointer · 42a268c2
      由 Richard Henderson 提交于 
      This is improved type checking for the translators -- it's no longer
possible to accidentally swap arguments to the branch functions.

Note that the code generating backends still manipulate labels as int.

With notable exceptions, the scope of the change is just a few lines
for each target, so it's not worth building extra machinery to do this
change in per-target increments.

      exec.c: Drop TARGET_HAS_ICE define and checks · ec53b45b
      由 Peter Maydell 提交于 
      The TARGET_HAS_ICE #define is intended to indicate whether a target-*
guest CPU implementation supports the breakpoint handling. However,
all our guest CPUs have that support (the only two which do not
define TARGET_HAS_ICE are unicore32 and openrisc, and in both those
cases the bp support is present and the lack of the #define is just
a bug). So remove the #define entirely: all new guest CPU support
should include breakpoint handling as part of the basic implementation.

      qemu-log: add log category for MMU info · 339aaf5b
      由 Antony Pavlov 提交于 
      Running barebox on qemu-system-mips* with '-d unimp' overloads
stderr by very very many mips_cpu_handle_mmu_fault() messages:

  mips_cpu_handle_mmu_fault address=b80003fd ret 0 physical 00000000180003fd prot 3
  mips_cpu_handle_mmu_fault address=a0800884 ret 0 physical 0000000000800884 prot 3
  mips_cpu_handle_mmu_fault pc a080cd80 ad b80003fd rw 0 mmu_idx 0

So it's very difficult to find LOG_UNIMP message.

The mips_cpu_handle_mmu_fault() messages appear on enabling ANY
logging! It's not very handy.

Adding separate log category for *_cpu_handle_mmu_fault()
logging fixes the problem.
