Keys which send more than one scancode (esp. windows key) weren't handled
correctly since commit 1ff5eedd. Two events were put into the input event
queue but only one was processed. This fixes this by fetching all pending

Laszlo Ersek 07abe45c48 hw/arm: pass pristine kernel image to guest firmware over fw_cfg
Introduce the new boolean field "arm_boot_info.firmware_loaded". When this
field is set, it means that the portion of guest DRAM that the VCPU
normally starts to execute, or the pflash chip that the VCPU normally
starts to execute, has been populated by board-specific code with
full-fledged guest firmware code, before the board calls
arm_load_kernel().

Simultaneously, "arm_boot_info.firmware_loaded" guarantees that the board
code has set up the global firmware config instance, for arm_load_kernel()
to find with fw_cfg_find().

Guest kernel (-kernel) and guest firmware (-bios, -pflash) has always been
possible to specify independently on the command line. The following cases
should be considered:

nr  -bios    -pflash  -kernel  description
             unit#0
--  -------  -------  -------  -------------------------------------------
1   present  present  absent   Board code rejects this case, -bios and
    present  present  present  -pflash unit#0 are exclusive. Left intact
                               by this patch.

2   absent   absent   present  Traditional kernel loading, with qemu's
                               minimal board firmware. Left intact by this
                               patch.

3   absent   present  absent   Preexistent case for booting guest firmware
    present  absent   absent   loaded with -bios or -pflash. Left intact
                               by this patch.

4   absent   absent   absent   Preexistent case for not loading any
                               firmware or kernel up-front. Left intact by
                               this patch.

5   present  absent   present  New case introduced by this patch: kernel
    absent   present  present  image is passed to externally loaded
                               firmware in unmodified form, using fw_cfg.

An easy way to see that this patch doesn't interfere with existing cases
is to realize that "info->firmware_loaded" is constant zero at this point.
Which makes the "outer" condition unchanged, and the "inner" condition
(with the fw_cfg-related code) dead.

Laszlo Ersek 578f3c7b08 arm: add fw_cfg to "virt" board
fw_cfg already supports exposure over MMIO (used in ppc/mac_newworld.c,
ppc/mac_oldworld.c, sparc/sun4m.c); we can easily add it to the "virt"
board.

Because MMIO access is slow on ARM KVM, we enable the guest, with
fw_cfg_init_mem_wide(), to transfer up to 8 bytes with a single access.
This has been measured to speed up transfers up to 7.5-fold, relative to
single byte data access, on both ARM KVM and x86_64 TCG.

The MMIO register block of fw_cfg is advertized in the device tree. As
base address we pick 0x09020000, which conforms to the comment preceding
"a15memmap": it falls in the miscellaneous device I/O range 128MB..256MB,
and it is aligned at 64KB. The DTB properties follow the documentation in
the Linux source file "Documentation/devicetree/bindings/arm/fw-cfg.txt".

fw_cfg automatically exports a number of files to the guest; for example,
"bootorder" (see fw_cfg_machine_reset()).

Laszlo Ersek 6c87e3d596 fw_cfg_mem: expose the "data_width" property with fw_cfg_init_mem_wide()
We rebase fw_cfg_init_mem() to the new function for compatibility with
current callers.

The behavior of the (big endian) multi-byte data reads is best shown
with a qtest session.  Here, we are reading the first six bytes of
the UUID

    $ arm-softmmu/qemu-system-arm -M virt -machine accel=qtest \
         -qtest stdio -uuid 4600cb32-38ec-4b2f-8acb-81c6ea54f2d8
>>> writew 0x9020008 0x0200
<<< OK
>>> readl 0x9020000
<<< OK 0x000000004600cb32

Remember this is big endian.  On big endian machines, it is stored
directly as 0x46 0x00 0xcb 0x32.

On a little endian machine, we have to first swap it, so that it becomes
0x32cb0046.  When written to memory, it becomes 0x46 0x00 0xcb 0x32
again.

Reading byte-by-byte works too, of course:

>>> readb 0x9020000
<<< OK 0x0000000000000038
>>> readb 0x9020000
<<< OK 0x00000000000000ec

Here only a single byte is read at a time, so they are read in order
similar to the 1-byte data port that is already in PPC and SPARC
machines.

Laszlo Ersek cfaadf0e89 fw_cfg_mem: introduce the "data_width" property
The "data_width" property is capable of changing the maximum valid access
size to the MMIO data register, and resizes the memory region similarly,
at device realization time.

The default value of "data_memwidth" is set so that we don't yet diverge
from "fw_cfg_data_mem_ops".

Most of the fw_cfg_mem users will stick with the default, and for them we
should continue using the statically allocated "fw_cfg_data_mem_ops". This
is beneficial for debugging because gdb can resolve pointers referencing
static objects to the names of those objects.

Laszlo Ersek 5712db6ae5 fw_cfg: hard separation between the MMIO and I/O port mappings
We are going to introduce a wide data register for fw_cfg, but only for
the MMIO mapped device. The wide data register will also require the
tightening of endiannesses.

However we don't want to touch the I/O port mapped fw_cfg device at all.

Currently QEMU provides a single fw_cfg device type that can handle both
I/O port and MMIO mapping. This flexibility is not actually exploited by
any board in the tree, but it renders restricting the above changes to
MMIO very hard.

Therefore, let's derive two classes from TYPE_FW_CFG: TYPE_FW_CFG_IO and
TYPE_FW_CFG_MEM.

TYPE_FW_CFG_IO incorporates the base I/O port and the related combined
MemoryRegion. (NB: all boards in the tree that use the I/O port mapped
flavor opt for the combined mapping; that is, when the data port overlays
the high address byte of the selector port. Therefore we can drop the
capability to map those I/O ports separately.)

TYPE_FW_CFG_MEM incorporates the base addresses for the MMIO selector and
data registers, and their respective MemoryRegions.

The "realize" and "props" class members are specific to each new derived
class, and become unused for the base class. The base class retains the
"reset" member and the "vmsd" member, because the reset functionality and
the set of migrated data are not specific to the mapping.

The new functions fw_cfg_init_io() and fw_cfg_init_mem() expose the
possible mappings in separation. For now fw_cfg_init() is retained as a
compatibility shim that enforces the above assumptions.

Greg Bellows 223a72f117 target-arm: Breakout integratorcp and versatilepb cpu init
This commit changes the integratorcp and versatilepb CPU initialization from
using the generic ARM cpu_arm_init function to doing it inline.  This is
necessary in order to allow CPU configuration changes to occur between CPU
instance initialization and realization.  Specifically, this change is in
preparation for disabling CPU EL3 support.

Greg Bellows e5a5604f8f target-arm: Set CPU has_el3 prop during virt init
Adds setting of the CPU has_el3 property based on the virt machine
secure state property during initialization.  This enables/disables EL3
state during start-up.  Changes include adding an additional secure state
boolean during virt CPU initialization.  Also disables the ARM secure boot
by default.

Greg Bellows c8e829b7bf target-arm: Add arm_boot_info secure_boot control
Adds the secure_boot boolean field to the arm_boot_info descriptor.  This
fields is used to indicate whether Linux should boot into secure or non-secure
state if the ARM EL3 feature is enabled.  The default is to leave the CPU in an
unaltered reset state.  On EL3 enabled systems, the reset state is secure and
can be overridden by setting the added field to false.

Previously, some EL3 registers were restricted to the ARMv8 list under the
impression that they were not needed on ARMv7.  However, this is not the case
as the ARMv7/32-bit variants rely on the ARMv8/64-bit variants to handle
migration and reset.  For this reason they must always exist.

When stopping an audio voice, call the audio backend's fini
method before calling audio_pcm_hw_free_resources_ rather than
afterwards. This allows backends which use helper threads (like
pulseaudio) to terminate those threads before the conv_buf or
mix_buf are freed and avoids race conditions where the helper
may access a NULL pointer or freed memory.
