The PIPE_REG_ACCESS_PARAMS structure can be one of two sizes depending
on the type of host kernel. As the pipe code is shared between both
32 bit and 64 bit worlds it needs to be able to handle both.
Introspecting the CPU type is impractical as a 64 bit CPU may be booting
a 32 bit kernel. Fortunately due to the overlap of the structures it's
possible to detect the use of a 64 bit structure as it implies a
non-zero value of the (currently) unused flags field.
This also opens the way to the 32 bit code using the 64 bit structure at
a later date.

Version of the android pipe pingpong test backend using virtserial
|
|
Users of virtio-serial may want to know when a port becomes writable. A
port can stop accepting writes if the guest port is open but not being
read from. In this case, data gets queued up in the virtqueue, and
after the vq is full, writes to the port do not succeed.
When the guest reads off a vq element, and adds a new one for the host
to put data in, we can tell users the port is available for more writes,
via the new ->guest_writable() callback.

On startup, start listening on the console and ADB ports automatically,
using the same "start at 5554 and work up until we find a pair of
ports which we can listen on" algorithm as the classic emulator.

The Android adbd daemon running inside Android VMs on the emulator
expect to be able to talk to a backend named "qemud:adb" (for historical
reasons).
The backend will carry out a handshake:
1. Listen for connections from the host adb server on
adb_port = <5555 + (2 * emulator instance id)>.
2. Connect to the local adb server on port 5037 if it's available.
3. Listen for and accept the beginning of the handshake with the adbd
daemon (adbd sends 'accept' over the write).
4. After the adb backend detects a connection on <adb_port>, it sends
back an "ok" string to adbd.
5. The adb backend will not send any more data over the pipe until it
recognizes a 'start' request, which means the adbd is ready to
receive data from the host ADB server.
Once the above process is complete, the adb backend will consume
everything it receives on the socket connected on <adb_port> and send it
over the adb pipe and will consume everything it receives over the adb
pipe and send it on the socket connected on <adb_port>.

The Android Pipe main implementation file should only contain the actual
implementation. Keeping all that test backend implementation code in
there just makes it confusing to grep in the file and figure out what is
going on.
This could be made dependent on some sort of debug flag to avoid
compiling test code as part of shipped binaries in the future.

This brings in the android emulator pipe code from the current aosp-qemu
master branch. It works with and has been tested with the pingpong
pipe device. Currently the device cannot save and restore.
- remove dependency on android utils (ANEW/ASTRDUP/AFREE)
- detach from the goldfish_device bus bits (inc irq raising)
- import a few helper functions (uint64_set_high/low, goldfish_guest_is_64bit)
- disable the VM save/restore code
- use current_cpu for memory translation ops instead of cpu_single_env
- fix debugging prints using portable formats
- common code path for translating vaddr->qemu addr*
- make some debug statments user-visible (unimp and guest errors)
There is a hacking backlink between AndroidPipeState and the PipeDevice
stuff (which should be merged cleanly later) just so we can get back to
->irq when we need to.

Add a new machine model for the 64-bit ARM Android emulator.
This is based heavily on the 'virt' machine model, and like
that we also create a device tree to pass to the guest kernel.
The major difference is that this board will have all the
Android-specific devices in it.
We leave space for putting in the goldfish_audio device but do
not actually enable it for now, since audio is not an initial
requirement and has not been tested.

but are never referenced by the kernel. Revisit on top of the new qemu

HACK: goldfish_fb: disable UI rotation events
It's not clear how this worked or how to port it to the new display API,
so disable it for now

Although the milkymist display device is indeed RGB565, it is
bigendian, so we can't actually borrow its drawfn helpers.
Implement our own instead.
After an FB_SET_BASE write, the guest is waiting for us to complete an
update cycle and notify it (via the FB_INT_BASE_UPDATE_DONE interrupt
status bit). Force the graphics backend to actually do a redraw
immediately; this avoids the guest timing out and producing periodic
"goldfish_fb_pan_display: timeout waiting for base update" warnings
on displays like VNC which make an effort to avoid redraw.
goldfish_fb: Don't use uninitialized ymin if screen is blank
Initialize ymin in the code path taken if the screen is blank,

When a QMP client changes the polling interval time by setting
the guest-stats-polling-interval property, the interval value
is stored and manipulated as an int64_t variable.
However, the balloon_stats_change_timer() function, which is
used to set the actual timer with the interval value, takes
an int instead, causing an overflow for big interval values.
This commit fix this bug by changing balloon_stats_change_timer()
to take an int64_t and also it limits the polling interval value
to UINT_MAX to avoid other kinds of overflow.
