We have different types of parents: block nodes, block backends and
jobs. So, it makes sense to specify type together with name.
Next, this handler us used to compose an error message about permission
conflict. And permission conflict occurs in a specific place of block
graph. We shouldn't report
The logic around **child is not obvious: this reference is used not
only to return resulting child, but also to rollback NULL value on
transaction abort.
So, let's add documentation and some assertions.
While being here, drop extra declaration of bdrv_attach_child_noperm().

Now permissions are updated as follows:
1. do graph modifications ignoring permissions
2. do permission update
(of course, we rollback [1] if [2] fails)
So, on stage [2] we can't say which users are "old" and which are
"new" and exist only since [1]. And current error message is a bit
outdated
All child classes have this callback. So, drop unreachable code.
Still add an assertion to bdrv_attach_child_common(), to early detect
bad classes.

This is the expected behavior if you pass an image to gdb before

Since QEMU maintains TLB entries keyed by the device ID, there is no separate
device entry cache. This means we need to invalidate all translations keyed by
the device ID.

These two commands are missing when adding the QMP sister commands. Add them,
so developers can play with them easier.

Hi Bin,
Thanks for the response.
I think the issue currently is that if I keep the "wait=on" and launch
minicom on "unix\#serial1.sock" then nothing happens.
Qemu keeps waiting for the connection on serial1 and no logs for uboot and
Kernel appears on the serial1.
Thanks

test_socket hangs randomly in connect(), especially when run without
qemu. Apparently the reason is that linux started treating backlog
value of 0 literally instead of rounding it up since v4.4 (commit
ef547f2ac16b).
So set it to 1 instead.

Please consider this patch for the QEMU 6.0 stable release. The bug
was introduced in QEMU 6.0.

valgrind fails to start under linux-user, one of the reasons being that
it tries to query all the sigactions, which qemu (unlike the real
kernel) doesn't allow for SIGKILL/SIGSTOP.
Patch 1 lifts this restriction, patch 2 adds a test.
Ilya Leoshkevich (2):
linux-user: Let sigaction query SIGKILL
The kernel allows doing this, so let's allow this in qemu as well.
Valgrind relies on this.

This is a quality of life helper for plugins so they don't need to
re-implement symbol lookup when dumping an address. The strings are
constant so don't need to be duplicated. One minor tweak is to return
NULL instead of a zero length string to show lookup failed.
Based-on: 20210530063712.6832-4-m
We will shortly be interested in distinguishing pointers
from integers in the helper's declaration, as well as a
true void return. We currently have two parallel 1 bit
fields; merge them and expand to a 3 bit field.
Our current maximum is 7 helper arguments, plus the return
makes 8 * 3 = 24 bits
As noted by qemu-plugins.h, plugins can neither read nor write
guest registers.
