1847b7ba70 linux-user: Fix target FS_IOC_GETFLAGS and FS_IOC_SETFLAGS numbers
We were defining TARGET_FS_IOC_GETFLAGS and TARGET_FS_IOC_SETFLAGS
using the host 'long' type in the size field, which meant that
they had the wrong values if the host and guest had different
sized longs. Switch to abi_long instead.

This fixes a bug where these ioctls don't work on 32-bit guests
on 64-bit hosts (and makes the LTP test 'setxattr03' pass
where it did not previously.)

18e80c55bb linux-user: Tidy and enforce reserved_va initialization
We had a check using TARGET_VIRT_ADDR_SPACE_BITS to make sure
that the allocation coming in from the command-line option was
not too large, but that didn't include target-specific knowledge
about other restrictions on user-space.

Remove several target-specific hacks in linux-user/main.c.

For MIPS and Nios, we can replace them with proper adjustments
to the respective target's TARGET_VIRT_ADDR_SPACE_BITS definition.

For ARM, we had no existing ifdef but I suspect that the current
default value of 0xf7000000 was chosen with this in mind.  Define
a workable value in linux-user/arm/, and also document why the
special case is required.

de258eb07d tcg: Fix off-by-one in assert in page_set_flags
Most of the users of page_set_flags offset (page, page + len) as
the end points.  One might consider this an error, since the other
users do supply an endpoint as the last byte of the region.

However, the first thing that page_set_flags does is round end UP
to the start of the next page.  Which means computing page + len - 1
is in the end pointless.  Therefore, accept this usage and do not
assert when given the exact size of the vm as the endpoint.

e568f9df08 linux-user: Allow -R values up to 0xffff0000 for 32-bit ARM guests
The 32-bit ARM validate_guest_space() check tests whether the
specified -R value leaves enough space for us to put the
commpage in at 0xffff0f00. However it was incorrectly doing
a <= check for the check against (guest_base + guest_size),
which meant that it wasn't permitting the guest space to
butt right up against the commpage.

Fix the comparison, so that -R values all the way up to 0xffff0000
work correctly.

bcd5ac9bcb ui: convert common input code to keycodemapdb
Replace the number_to_qcode, qcode_to_number and linux_to_qcode
tables with automatically generated tables.

Missing entries in linux_to_qcode now fixed:

  KEY_LINEFEED -> Q_KEY_CODE_LF
  KEY_KPEQUAL -> Q_KEY_CODE_KP_EQUALS
  KEY_COMPOSE -> Q_KEY_CODE_COMPOSE
  KEY_AGAIN -> Q_KEY_CODE_AGAIN
  KEY_PROPS -> Q_KEY_CODE_PROPS
  KEY_UNDO -> Q_KEY_CODE_UNDO
  KEY_FRONT -> Q_KEY_CODE_FRONT
  KEY_COPY -> Q_KEY_CODE_COPY
  KEY_OPEN -> Q_KEY_CODE_OPEN
  KEY_PASTE -> Q_KEY_CODE_PASTE
  KEY_CUT -> Q_KEY_CODE_CUT
  KEY_HELP -> Q_KEY_CODE_HELP
  KEY_MEDIA -> Q_KEY_CODE_MEDIASELECT

In addition, some fixes:

 - KEY_PLAYPAUSE now maps to Q_KEY_CODE_AUDIOPLAY, instead of
   KEY_PLAYCD. KEY_PLAYPAUSE is defined across almost all scancodes
   sets, while KEY_PLAYCD only appears in AT set1, so the former is
   a more useful mapping.

Missing entries in qcode_to_number now fixed:

  Q_KEY_CODE_AGAIN -> 0x85
  Q_KEY_CODE_PROPS -> 0x86
  Q_KEY_CODE_UNDO -> 0x87
  Q_KEY_CODE_FRONT -> 0x8c
  Q_KEY_CODE_COPY -> 0xf8
  Q_KEY_CODE_OPEN -> 0x64
  Q_KEY_CODE_PASTE -> 0x65
  Q_KEY_CODE_CUT -> 0xbc
  Q_KEY_CODE_LF -> 0x5b
  Q_KEY_CODE_HELP -> 0xf5
  Q_KEY_CODE_COMPOSE -> 0xdd
  Q_KEY_CODE_KP_EQUALS -> 0x59
  Q_KEY_CODE_MEDIASELECT -> 0xed

In addition, some fixes:

 - Q_KEY_CODE_MENU was incorrectly mapped to the compose
   scancode (0xdd) and is now mapped to 0x9e
 - Q_KEY_CODE_FIND was mapped to 0xe065 (Search) instead
   of to 0xe041 (Find)
 - Q_KEY_CODE_HIRAGANA was mapped to 0x70 (Katakanahiragana)
   instead of of 0x77 (Hirigana)
 - Q_KEY_CODE_PRINT was mapped to 0xb7 which is not a defined
   scan code in AT set 1, it is now mapped to 0x54 (sysrq)

927128222b ui: add keycodemapdb repository as a GIT submodule
The https://gitlab.com/keycodemap/keycodemapdb/ repo contains a
data file mapping between all the different scancode/keycode/keysym
sets that are known, and a tool to auto-generate lookup tables for
different combinations.

It is used by GTK-VNC, SPICE-GTK and libvirt for mapping keys.
Using it in QEMU will let us replace many hand written lookup
tables with auto-generated tables from a master data source,
reducing bugs. Adding new QKeyCodes will now only require the
master table to be updated, all ~20 other tables will be
automatically updated to follow.

47bb908dd1 docker: don't rely on submodules existing in the main checkout
When building the tarball to pass into the docker/vm test image,
the code relies on the git submodules being checked out in the
main checkout.

ie if the developer has not run 'git submodule update --init dtc'
many of the docker tests will fail due to the libfdt package not
being present in the test images. Patchew manually checks out the
dtc submodule in the main git checkout, but this is a bad idea.

When running tests we want to have a predictable set of submodules
included in the source that's tested. The build environment is
completely independent of the developers host OS, so the submodules
the developer has checked out should not be considered relevant for
the tests.

This changes the archive-source.sh script so that it clones the
current git checkout into a temporary directory, checks out a
fixed set of submodules, builds the tarball and finally removes
the temporary git clone.

aef45d51d1 build: automatically handle GIT submodule checkout for dtc
Currently if DTC is required by configure and not available in the host
OS install, we exit with an error message telling the user to checkout a
git submodule or install the library.

This introduces automatic handling of the git submodule checkout process
and enables it for dtc. This only runs if building from GIT, so users of
release tarballs still need the system library install. The current state
of the git checkout is stashed in .git-submodule-status, and a helper
program is used to determine if this state matches the desired submodule
state. A dependency against 'Makefile' ensures that the submodule state
is refreshed at the start of the build process

b95b5a0a52 tests/prom-env: Bump the timeout, and test pseries only in slow mode
If QEMU has been compiled with the flags --enable-tcg-interpreter and
--enable-debug, the guest is running incredibly slow. The prom-env
test is approximately 10 times slower than normal in this case, and
it takes up to 500 seconds until the test with the pseries machine
finishs. While we should still look for ways to speed up the test
on the pseries machine here, let's bump the timeout to 600 seconds to
allow the test to pass with this unusal configuration already now.
Also move the pseries test into the "slow" category - since it is
really a very slow test.

ab06ec4357 tests/pxe: Test more NICs when running in SPEED=slow mode
The pxe-test is a very good test to excercise NICs, thus we should use
it to test all NICs that can be used by the BIOS for booting via network.
However, to avoid that the default testing time increases too much, the
additional NICs are only tested in the "make check SPEED=slow" mode.

The virtio-net NIC on ppc64 is now also only tested in slow mode, since
the test on ppc64 is really quite slow and we've got test coverage for
virtio-net in big endian mode now on s390x, too.

a93c8d828a virtio-pci: Replace modern_as with direct access to modern_bar
The modern bar is accessed now via yet another address space created just
for that purpose and it does not really need FlatView and dispatch tree
as it has a single memory region so it is just a waste of memory. Things
get even worse when there are dozens or hundreds of virtio-pci devices -
since these address spaces are global, changing any of them triggers
rebuilding all address spaces.

This replaces indirect accesses to the modern BAR with a simple lookup
and direct calls to memory_region_dispatch_read/write.

This is expected to save lots of memory at boot time after applying:

37ef70be6a virtio: fix descriptor counting in virtqueue_pop
While changing the s/g list allocation, commit 3b3b0628
also changed the descriptor counting to count iovec entries
as split by cpu_physical_memory_map(). Previously only the
actual descriptor entries were counted and the split into
the iovec happened afterwards in virtqueue_map().
Count the entries again instead to avoid erroneous
"Looped descriptor" errors.

fd3b02c889 pci: Add INTERFACE_CONVENTIONAL_PCI_DEVICE to Conventional PCI devices
Add INTERFACE_CONVENTIONAL_PCI_DEVICE to all direct subtypes of
TYPE_PCI_DEVICE, except:

1) The ones that already have INTERFACE_PCIE_DEVICE set:

* base-xhci
* e1000e
* nvme
* pvscsi
* vfio-pci
* virtio-pci
* vmxnet3

2) base-pci-bridge

Not all PCI bridges are Conventional PCI devices, so
INTERFACE_CONVENTIONAL_PCI_DEVICE is added only to the subtypes
that are actually Conventional PCI:

* dec-21154-p2p-bridge
* i82801b11-bridge
* pbm-bridge
* pci-bridge

The direct subtypes of base-pci-bridge not touched by this patch
are:

* xilinx-pcie-root: Already marked as PCIe-only.
* pcie-pci-bridge: Already marked as PCIe-only.
* pcie-port: all non-abstract subtypes of pcie-port are already
  marked as PCIe-only devices.

3) megasas-base

Not all megasas devices are Conventional PCI devices, so the
interface names are added to the subclasses registered by
megasas_register_types(), according to information in the
megasas_devices[] array.

"megasas-gen2" already implements INTERFACE_PCIE_DEVICE, so add
INTERFACE_CONVENTIONAL_PCI_DEVICE only to "megasas".

QEMU with the pcie-pci-bridge device crashes if the guest board doesn't support MSI,
e.g. 'qemu-system-ppc64 -M prep -device pcie-pci-bridge'.
This is caused by wrong pcie-pci-bridge instantiation error handling. This patch fixes this issue
by falling back to legacy INTx if MSI is not available.
Also set the bridge's 'msi' property default value to 'auto' in order to trigger errors
only when user explicitly set msi=on.

5c0ba1be37 virtio/vhost: reset dev->log after syncing
vhost_log_put() is called to decomission the dirty log between qemu and
a vhost device when stopping the device. Such a call can happen from
migration_completion().

Present code sets dev->log_size to zero too early in vhost_log_put(),
causing the sync check to always return false. As a consequence, the
last pass on the dirty bitmap never happens at the end of migration.

If a vhost device was busy (writing to guest memory) until the last
moments before vhost_virtqueue_stop(), this error will result in guest
memory corruption (at least) following migrations.
