2020-11-17char-stdio: Fix QMP default for 'signal'Kevin Wolf1-3/+1
Commit 02c4bdf1 tried to make signal=on the default for stdio chardevs except for '-serial mon:stdio', but it forgot about QMP and accidentally switched the QMP default from true (except for -nographic) to false (always). The documentation was kept unchanged and still describes the opposite of the old behaviour (which is an even older documentation bug). Fix all of this by making signal=true the default in ChardevStdio and documenting it as such.

2018-06-28chardev: don't splatter terminal settings on exit if not previously setDaniel P. Berrangé1-2/+4
The stdio chardev finalize method calls term_exit() to restore the original terminal settings that were saved in the "oldtty" global. If the qemu_chr_open_stdio() method exited with an error, we might not have any original terminal settings saved in "oldtty" yet. eg $ qemu-system-x86_64 -monitor stdio -daemonize qemu-system-x86_64: -monitor stdio: cannot use stdio with -daemonize will cause QEMU to splatter the terminal settings with an all-zeros "struct termios", with predictably unpleasant results. Fortunately the existing "stdio_in_use" flag is suitable witness for whether "oldtty" contains settings that need restoring. Signed-off-by: Daniel P.

2018-06-08chardev: Restore CR,LF on stdioPhilippe Mathieu-Daudé1-1/+1
Remove the 'stair-step output' on stdio.

2018-06-01char: Remove unwanted crlf conversionPatryk Olszewski1-1/+1
This patch fixes a bug in serial that made it almost impossible for guest to communicate with devices through host's serial. OPOST flag in c_oflag enables output processing letting other flags in c_oflag take effect. Usually in c_oflag ONLCR flag is also set, which causes crlf to be sent in place of lf. This breaks binary transmissions. Unsetting OPOST flag turns off any output processing which fixes the bug.

2018-02-09Move include qemu/option.h from qemu-common.h to actual usersMarkus Armbruster1-1/+2
qemu-common.h includes qemu/option.h, but most places that include the former don't actually need the latter. Drop the include, and add it to the places that actually need it. While there, drop superfluous includes of both headers, and separate #include from file comment with a blank line. This cleanup makes the number of objects depending on qemu/option.h drop from 4545 (out of 4743) to 284 in my "build everything" tree.
