      qom/cpu: Simplify how CPUClass:cpu_dump_state() prints · 90c84c56
      由 Markus Armbruster 提交于 
      CPUClass method dump_statistics() takes an fprintf()-like callback and
a FILE * to pass to it.  Most callers pass fprintf() and stderr.
log_cpu_state() passes fprintf() and qemu_log_file.
hmp_info_registers() passes monitor_fprintf() and the current monitor
cast to FILE *.  monitor_fprintf() casts it right back, and is
otherwise identical to monitor_printf().

The callback gets passed around a lot, which is tiresome.  The
type-punning around monitor_fprintf() is ugly.

Drop the callback, and call qemu_fprintf() instead.  Also gets rid of
the type-punning, since qemu_fprintf() takes NULL instead of the
current monitor cast to FILE *.

      CPUClass method dump_statistics() takes an fprintf()-like callback and

      target: Clean up how the dump_mmu() print · fad866da
      由 Markus Armbruster 提交于 
      The various dump_mmu() take an fprintf()-like callback and a FILE * to
pass to it, and so do their helper functions.  Passing around callback
and argument is rather tiresome.

Most dump_mmu() are called only by the target's hmp_info_tlb().  These
all pass monitor_printf() cast to fprintf_function and the current
monitor cast to FILE *.

SPARC's dump_mmu() gets also called from target/sparc/ldst_helper.c a
few times #ifdef DEBUG_MMU.  These calls pass fprintf() and stdout.

The type-punning is technically undefined behaviour, but works in
practice.  Clean up: drop the callback, and call qemu_printf()
instead.

      target: Simplify how the TARGET_cpu_list() print · 0442428a
      由 Markus Armbruster 提交于 
      The various TARGET_cpu_list() take an fprintf()-like callback and a
FILE * to pass to it.  Their callers (vl.c's main() via list_cpus(),
bsd-user/main.c's main(), linux-user/main.c's main()) all pass
fprintf() and stdout.  Thus, the flexibility provided by the (rather
tiresome) indirection isn't actually used.

Drop the callback, and call qemu_printf() instead.

Calling printf() would also work, but would make the code unsuitable
for monitor context without making it simpler.

      target/ppc: Enable reporting of SPRs to GDB · 707c7c2e
      由 Fabiano Rosas 提交于 
      This allows reading and writing of SPRs via GDB:

(gdb) p/x $srr1
$1 = 0x8000000002803033

(gdb) p/x $pvr
$2 = 0x4b0201
(gdb) set $pvr=0x4b0000
(gdb) p/x $pvr
$3 = 0x4b0000

The `info` command can also be used:
(gdb) info registers spr

For this purpose, GDB needs to be provided with an XML description of
the registers (see the gdb-xml directory for examples) and a set of
callbacks for reading and writing the registers must be defined.

The XML file in this case is created dynamically, based on the SPRs
already defined in the machine. This way we avoid the need for several
XML files to suit each possible ppc machine.

The gdb_{get,set}_spr_reg callbacks take an index based on the order
the registers appear in the XML file. This index does not match the
actual location of the registers in the env->spr array so the
gdb_find_spr_idx function does that conversion.

Note: GDB currently needs to know the guest endianness in order to
properly print the registers values. This is done automatically by GDB
when provided with the ELF file or explicitly with the `set endian
<big|little>` command.

      ppc: Fix duplicated typedefs to be able to compile with Clang in gnu99 mode · 0d8d6a24
      由 Thomas Huth 提交于 
      When compiling the ppc code with clang and -std=gnu99, there are a
couple of warnings/errors like this one:

  CC      ppc64-softmmu/hw/intc/xics.o
In file included from hw/intc/xics.c:35:
include/hw/ppc/xics.h:43:25: error: redefinition of typedef 'ICPState' is a C11 feature
      [-Werror,-Wtypedef-redefinition]
typedef struct ICPState ICPState;
                        ^
target/ppc/cpu.h:1181:25: note: previous definition is here
typedef struct ICPState ICPState;
                        ^
Work around the problems by including the proper headers in spapr.h
and by using struct forward declarations in cpu.h.

      target/ppc: add external PID support · 50728199
      由 Roman Kapl 提交于 
      External PID is a mechanism present on BookE 2.06 that enables application to
store/load data from different address spaces. There are special version of some
instructions, which operate on alternate address space, which is specified in
the EPLC/EPSC regiser.

This implementation uses two additional MMU modes (mmu_idx) to provide the
address space for the load and store instructions. The QEMU TLB fill code was
modified to recognize these MMU modes and use the values in EPLC/EPSC to find
the proper entry in he PPC TLB. These two QEMU TLBs are also flushed on each
write to EPLC/EPSC.

Following instructions are implemented: dcbfep dcbstep dcbtep dcbtstep dcbzep
dcbzlep icbiep lbepx ldepx lfdepx lhepx lwepx stbepx stdepx stfdepx sthepx
stwepx.

Following vector instructions are not: evlddepx evstddepx lvepx lvepxl stvepx
stvepxl.

      target/ppc: Allow cpu compatiblity checks based on type, not instance · ad99d04c
      由 David Gibson 提交于 
      ppc_check_compat() is used in a number of places to check if a cpu object
supports a certain compatiblity mode, subject to various constraints.

It takes a PowerPCCPU *, however it really only depends on the cpu's class.
We have upcoming cases where it would be useful to make compatibility
checks before we fully instantiate the cpu objects.

ppc_type_check_compat() will now make an equivalent check, but based on a
CPU's QOM typename instead of an instantiated CPU object.

We make use of the new interface in several places in spapr, where we're
essentially making a global check, rather than one specific to a particular
cpu.  This avoids some ugly uses of first_cpu to grab a "representative"
instance.
