ppc patch queue for 2022-10-29:
This queue has the second part of the ppc4xx_sdram cleanups, doorbell
instructions for POWER8, new pflash handling for the e500 machine and a
Radix MMU regression fix.
It also has a lot of performance optimizations in the PowerPC emulation
done by the researchers of the Eldorado institute. Between using gvec
for VMX/VSX instructions, a full rework of the interrupt model and PMU
optimizations, they managed to drastically speed up the emulation of
powernv8/9/10 machines. Here's an example with avocado tests:
- with master:
tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv8:
PASS (38.89 s)
tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv9:
PASS (43.89 s)
- with this queue applied:
tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv8:
PASS (21.23 s)
tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv9:
PASS (22.58 s)
Other ppc machines, like pseries, also had a noticeable performance
boost.

target/ppc: Fix regression in Radix MMU
Commit
47e83d9107 ended up unintentionally changing the control flow
of ppc_radix64_process_scoped_xlate(). When guest_visible is false,
it must not raise an exception, even if the radix configuration is
not valid.
This regression prevented Linux boot in a nested environment with
L1 using TCG and emulating KVM (cap-nested-hv=on) and L2 using
KVM. L2 would hang on Linux's futex_init(), when it tested how a
futex_atomic_cmpxchg_inatomic() handled a fault, because L1 would
start a loop of trying to perform partition scoped translations
and raising exceptions.
Fixes:

6.39% of total time was being spent in helper_insns_inc(), on a

Overall, these instructions are the hardest ones to measure performance
as the gvec implementation is affected by the immediate. Above there are
5 different scenarios when it comes to immediate and 2 when it comes to
rept/loop combination. The immediates scenarios are: all bits are 0
therefore the target register should just be changed to 0, with 1 bit
set, with 2 bits set in a combination the new implementation can deal
with using gvec, 4 bits set and the new implementation can't deal with
it using gvec and all bits set. The rept/loop scenarios are high loop
and low rept (so it should spend more time executing it than translating
it) and high rept low loop (so it should spend more time translating it
than executing this code).
These comparisons are between the upstream version, a previous similar
implementation and a one with a cleaner code(this one).
For a comparison with o previous different implementation:

As some values are now decoded outside the helper and passed to it as an
argument the number of arguments of the helper increased, the number
of TCGop needed to load the arguments increased. I suspect that's why
the slow-down in the tests with a high REPT but low LOOP.

target/ppc: Moved XVTSTDC[DS]P to decodetree
Moved XVTSTDCSP and XVTSTDCDP to decodetree an restructured the helper
to be simpler and do all decoding in the decodetree (so XB, XT and DCMX
are all calculated outside the helper).
Obs: The tests in this one are slightly different, these are the sum of
these instructions with all possible immediate and those instructions
are repeated 10 times.

I'm not sure if it's worth to move those instructions. Comparing the

I'm not sure why vprtybd took so much more time.

The significant difference in performance when REPT is low and LOOP is
high I think is due to the fact that the new implementation has a higher
translation time, as when using a helper only 5 TCGop are used but with
the patch a total of 10 TCGop are needed (Power lacks a direct mul_vec
equivalent so this instruction is implemented with the help of 5 others,
vmuleu, vmulou, vmrgh, vmrgl and vpkum).

The netdev reports NETDEV_STREAM_CONNECTED event when the backend
is connected, and NETDEV_STREAM_DISCONNECTED when it is disconnected.
The NETDEV_STREAM_CONNECTED event includes the destination address.
This allows a system manager like libvirt to detect when the server
fails.
For instance with passt:
{ 'execute': 'qmp_capabilities' }
{ "return": { } }
{ "timestamp": { "seconds":
1666341395, "microseconds": 505347 },
"event": "NETDEV_STREAM_CONNECTED",
"data": { "netdev-id": "netdev0",
"addr": { "path": "/tmp/passt_1.socket", "type": "unix" } } }
[killing passt here]
{ "timestamp": { "seconds":
1666341430, "microseconds": 968694 },
"event": "NETDEV_STREAM_DISCONNECTED",
"data": { "netdev-id": "netdev0" } }

qemu-sockets: update socket_uri() and socket_parse() to be consistent
To be consistent with socket_uri(), add 'tcp:' prefix for inet type in
socket_parse(), by default socket_parse() use tcp when no prefix is
provided (format is host:port).
In socket_uri(), use 'vsock:' prefix for vsock type rather than 'tcp:'
because it makes a vsock address look like an inet address with CID
misinterpreted as host.

qapi: net: add stream and dgram netdevs
Copied from socket netdev file and modified to use SocketAddress
to be able to introduce new features like unix socket.
"udp" and "mcast" are squashed into dgram netdev, multicast is detected
according to the IP address type.
"listen" and "connect" modes are managed by stream netdev. An optional
parameter "server" defines the mode (off by default)
The two new types need to be parsed the modern way with -netdev, because
with the traditional way, the "type" field of netdev structure collides with
the "type" field of SocketAddress and prevents the correct evaluation of the
command line option. Moreover the traditional way doesn't allow to use
the same type (SocketAddress) several times with the -netdev option
(needed to specify "local" and "remote" addresses).
The previous commit paved the way for parsing the modern way, but
omitted one detail: how to pick modern vs. traditional, in
netdev_is_modern().
We want to pick based on the value of parameter "type". But how to
extract it from the option argument?
Parsing the option argument, either the modern or the traditional way,
extracts it for us, but only if parsing succeeds.
If parsing fails, there is no good option. No matter which parser we
pick, it'll be the wrong one for some arguments, and the error
reporting will be confusing.
Fortunately, the traditional parser accepts *anything* when called in
a certain way. This maximizes our chance to extract the value of
"type", and in turn minimizes the risk of confusing error reporting.
