Hi community,
I can think of 2 ways to use gdb+qemu to remotely debug arm64 kernel, by
enabling gdbstub within qemu to communicate with gdb.
I am wondering in the real-world practice, is this debug technique
helpful for debugging arm64 kernel?
Options are:

On success, sigtimedwait() returns a signal number that needs to be
translated from a host value to a target value.
This change also fixes issues with sigwait (that is implemented using
sigtimedwait()).

This series adds a passthrough JSON protocol block driver. Its filenames
are JSON objects prefixed by "json:". The objects are used as options
for opening another block device which will be the child of the JSON
device. Regarding this child device, the JSON driver behaves nearly the
same as raw_bsd
Add a JSON protocol driver which allows supplying block driver options
through the filename rather than separately. Other than that, it is a
pure passthrough driver which identifies itself as a filter.
This patch implements the functions bdrv_parse_filename(),
bdrv_file_open(), bdrv_close(), bdrv_
Add passthrough functions for bdrv_aio_discard(),
bdrv_co_write_zeroes(), bdrv_truncate() and bdrv_has_zero_init().
