ca6155c0f2 Merge tag 'patchew/20200219160953.13771-1-imammedo@redhat.com' of https://github.com/patchew-project/qemu into HEAD
This series removes ad hoc RAM allocation API (memory_region_allocate_system_memory)
and consolidates it around hostmem backend. It allows to

* resolve conflicts between global -mem-prealloc and hostmem's "policy" option,
  fixing premature allocation before binding policy is applied

* simplify complicated memory allocation routines which had to deal with 2 ways
  to allocate RAM.

* reuse hostmem backends of a choice for main RAM without adding extra CLI
  options to duplicate hostmem features.  A recent case was -mem-shared, to
  enable vhost-user on targets that don't support hostmem backends [1] (ex: s390)

* move RAM allocation from individual boards into generic machine code and
  provide them with prepared MemoryRegion.

* clean up deprecated NUMA features which were tied to the old API (see patches)
  - "numa: remove deprecated -mem-path fallback to anonymous RAM"
  - (POSTPONED, waiting on libvirt side) "forbid '-numa node,mem' for 5.0 and newer machine types"
  - (POSTPONED) "numa: remove deprecated implicit RAM distribution between nodes"

Introduce a new machine.memory-backend property and wrapper code that aliases
global -mem-path and -mem-alloc into automatically created hostmem backend
properties (provided memory-backend was not set explicitly given by user).
A bulk of trivial patches then follow to incrementally convert individual
boards to using machine.memory-backend provided MemoryRegion.

Board conversion typically involves:

* providing MachineClass::default_ram_size and MachineClass::default_ram_id
  so generic code could create default backend if user didn't explicitly provide
  memory-backend or -m options

* dropping memory_region_allocate_system_memory() call

* using convenience MachineState::ram MemoryRegion, which points to MemoryRegion
   allocated by ram-memdev

On top of that for some boards:

* missing ram_size checks are added (typically it were boards with fixed ram size)

* ram_size fixups are replaced by checks and hard errors, forcing user to
  provide correct "-m" values instead of ignoring it and continuing running.

After all boards are converted, the old API is removed and memory allocation
routines are cleaned up.

533eb415df arm/aspeed: actually check RAM size
It's supposed that SOC will check if "-m" provided
RAM size is valid by setting "ram-size" property and
then board would read back valid (possibly corrected
value) to map RAM MemoryReging with valid size.
It isn't doing so, since check is called only
indirectly from
  aspeed_sdmc_reset()->asc->compute_conf()
or much later when guest writes to configuration
register.

So depending on "-m" value QEMU end-ups with a warning
and an invalid MemoryRegion size allocated and mapped.
(examples:
 -M ast2500-evb -m 1M
    0000000080000000-000000017ffffffe (prio 0, i/o): aspeed-ram-container
      0000000080000000-00000000800fffff (prio 0, ram): ram
      0000000080100000-00000000bfffffff (prio 0, i/o): max_ram
 -M ast2500-evb -m 3G
    0000000080000000-000000017ffffffe (prio 0, i/o): aspeed-ram-container
      0000000080000000-000000013fffffff (prio 0, ram): ram
      [DETECTED OVERFLOW!] 0000000140000000-00000000bfffffff (prio 0, i/o): max_ram
)
On top of that sdmc falls back and reports to guest
"default" size, it thinks machine should have.

This patch makes ram-size check actually work and
changes behavior from a warning later on during
machine reset to error_fatal at the moment SOC.ram-size
is set so user will have to fix RAM size on CLI
to start machine.

It also gets out of the way mutable ram-size logic,
so we could consolidate RAM allocation logic around
pre-allocated hostmem backend (supplied by user or
auto created by generic machine code depending on
supplied -m/mem-path/mem-prealloc options.

068fe58cf9 mos6522: remove anh register
Register addr 1 is defined as buffer A with handshake (vBufAH),
register addr 15 is also defined as buffer A without handshake (vBufA).

As both addresses access the same register, remove the definition of
'anh' and use only 'a' (with VIA_REG_ANH and VIA_REG_A).

This allows to save and restore the content of the PRAM.
It may be useful if we want to check the configuration or to change it.

The backend is added using mtd interface, for instance:

    ... -drive file=pram.img,format=raw,if=mtd ...

where pram.img is the file where the data will be stored, its size must
be 256 bytes.

cd8843ff25 mos6522: fix T1 and T2 timers
With the Quadra 800 emulation, mos6522 timers processing can consume
until 70% of the host CPU time with an idle guest (I guess the problem
should also happen with PowerMac emulation).

On a recent system, it can be painless (except if you look at top), but
on an old host like a PowerMac G5 the guest kernel can be terribly slow
during the boot sequence (for instance, unpacking initramfs can take 15
seconds rather than only 3 seconds).

We can avoid this CPU overload by enabling QEMU internal timers only if
the mos6522 counter interrupts are enabled. Sometime the guest kernel
wants to read the counters values, but we don't need the timers to
update the counters.

With this patch applied, an idle Q800 consumes only 3% of host CPU time
(and the guest can boot in a decent time).

0fbe394a64 hw/misc/grlib_ahb_apb_pnp: Fix 8-bit accesses
The Plug & Play region of the AHB/APB bridge can be accessed
by various word size, however the implementation is clearly
restricted to 32-bit:

  static uint64_t grlib_apb_pnp_read(void *opaque, hwaddr offset, unsigned size)
  {
      APBPnp *apb_pnp = GRLIB_APB_PNP(opaque);

      return apb_pnp->regs[offset >> 2];
  }

Set the MemoryRegionOps::impl min/max fields to 32-bit, so
memory.c::access_with_adjusted_size() can adjust when the
access is not 32-bit.

This is required to run RTEMS on leon3, the grlib scanning
functions do byte accesses.

372a87a1d9 Do not use %m in common code to print error messages
The %m format specifier is an extension from glibc - and when compiling
QEMU for NetBSD, the compiler correctly complains, e.g.:

/home/qemu/qemu-test.ELjfrQ/src/util/main-loop.c: In function 'sigfd_handler':
/home/qemu/qemu-test.ELjfrQ/src/util/main-loop.c:64:13: warning: %m is only
 allowed in syslog(3) like functions [-Wformat=]
             printf("read from sigfd returned %zd: %m\n", len);
             ^
Let's use g_strerror() here instead, which is an easy-to-use wrapper
around the thread-safe strerror_r() function.

While we're at it, also convert the "printf()" in main-loop.c into
the preferred "error_report()".

19845504da hw/misc/bcm2835_mbox: Add trace events
Add trace events for read/write accesses and IRQ.

Properties are structures used for the ARM particular MBOX.
Since one call in bcm2835_property.c concerns the mbox block,
name this trace event in the same bcm2835_mbox* namespace.

Since the address_space_init() function takes a 'name' argument,
set it to correctly describe each address space:

794dcb54b3 trace: Remove trailing newline in events
While the tracing framework does not forbid trailing newline in
events format string, using them lead to confuse output.
It is the responsibility of the backend to properly end an event
line.

Some of our formats have trailing newlines, remove them.
