Andreas Färber 1bba0dc932 Rename cpu_reset() to cpu_state_reset()
Frees the identifier cpu_reset for QOM CPUs (manual rename).

Don't hide the parameter type behind explicit casts, use static
functions with strongly typed argument to indirect.

Peter Maydell 871708bf39 target-cris/opcode-cris.h: rename REG_PC/SP to CRIS_REG_PC/SP
The REG_PC constant used in opcode-cris.h can clash with a
similar define in system include files. In particular the
Ubuntu Lucid SPARC signal.h will define REG_PC, and since
qemu-common.h now includes signal.h this was causing compile
failures. Rename the constants to avoid this issue.
(NB that REG_SP is not actually used within QEMU.)

Blue Swirl 3e4571724f exec.h cleanup
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.

Stefan Weil e87b7cb0f0 Remove unused function parameters from gen_pc_load and rename the function
Function gen_pc_load was introduced in commit
d2856f1ad4.
The only reason for parameter searched_pc was
a debug statement in target-i386/translate.c.

Parameter puc was needed by target-sparc until
commit d7da2a1040.

Remove searched_pc from the debug statement and remove both
parameters from the parameter list of gen_pc_load.

As the function name gen_pc_load was also misleading,
it is now called restore_state_to_opc. This new name
was suggested by Peter Maydell, thanks.

v2: Remove last parameter, too, and rename the function.

v3: Fix [] typo in target-arm/translate.c.
    Fix wrong SHA1 object name in commit message (copy+paste error).

Paul Brook d4c430a80f Large page TLB flush
QEMU uses a fixed page size for the CPU TLB.  If the guest uses large
pages then we effectively split these into multiple smaller pages, and
populate the corresponding TLB entries on demand.

When the guest invalidates the TLB by virtual address we must invalidate
all entries covered by the large page.  However the address used to
invalidate the entry may not be present in the QEMU TLB, so we do not
know which regions to clear.

Implementing a full vaiable size TLB is hard and slow, so just keep a
simple address/mask pair to record which addresses may have been mapped by
large pages.  If the guest invalidates this region then flush the
whole TLB.

aliguori a1d1bb3101 Refactor and enhance break/watchpoint API (Jan Kiszka)
This patch prepares the QEMU cpu_watchpoint/breakpoint API to allow the
succeeding enhancements this series comes with.

First of all, it overcomes MAX_BREAKPOINTS/MAX_WATCHPOINTS by switching
to dynamically allocated data structures that are kept in linked lists.
This also allows to return a stable reference to the related objects,
required for later introduced x86 debug register support.

Breakpoints and watchpoints are stored with their full information set
and an additional flag field that makes them easily extensible for use
beyond pure guest debugging.

* Clean up the interrupt handling a bit.
* Connect some NOR flash to the test board.

edgar_igl bbaf29c769 * target-cris/op.c: Make sure the bit-test insn only updates the XNZ flags.
* target-cris/helper.c: Update ERP for user-mode simulation aswell.
* hw/etraxfs_timer.c: Support multiple timers.
* hw/etraxfs_ser.c: Multiple ports, the data just goes to stdout.

edgar_igl 4f400ab520 Cut the translation block after translating a break insn. This avoids an issue where QEMU finds an illegal CRIS insn while the guest is returning through a signal return trampoline.

j_mayer 6ebbf39000 Replace is_user variable with mmu_idx in softmmu core,
allowing support of more than 2 mmu access modes.
Add backward compatibility is_user variable in targets code when needed.
Implement per target cpu_mmu_index function, avoiding duplicated code
  and #ifdef TARGET_xxx in softmmu core functions.
Implement per target mmu modes definitions. As an example, add PowerPC
  hypervisor mode definition and Alpha executive and kernel modes definitions.
Optimize PowerPC case, precomputing mmu_idx when MSR register changes
  and using the same definition in code translation code.
