- Add an audio-oss sub-package - Add some new (mostly documentation) files in the package - Remove option --audio-drv-list because audio is detected by meson automatically in latest version. - Remove options --disable-jemalloc and --disable-tcmalloc which are changed in v6.2.0. - Update to v 6.2.0.

Subject: Make char muxer more robust wrt small FIFOs
|
|
|
|
Virtio-Console can only process one character at a time. Using it on S390
|
|
gave me strange "lags" where I got the character I pressed before when
|
|
pressing one. So I typed in "abc" and only received "a", then pressed "d"
|
|
but the guest received "b" and so on.
|
|
|
|
While the stdio driver calls a poll function that just processes on its
|
|
queue in case virtio-console can't take multiple characters at once, the
|
|
muxer does not have such callbacks, so it can't empty its queue.
|
|
|
|
To work around that limitation, I introduced a new timer that only gets
|
|
active when the guest can not receive any more characters. In that case
|
|
it polls again after a while to check if the guest is now receiving input.
|
|
|
|
This patch fixes input when using -nographic on s390 for me.
|

|
[AF: Rebased for v2.7.0-rc2]
|
|
[BR: minor edits to pass qemu's checkpatch script]
