2021-08-05chardev: mark explicitly first argument as poisonedMarc-André Lureau1-1/+1
Since commit 9894dc0cdcc397ee5b26370bc53da6d360a363c2 "char: convert from GIOChannel to QIOChannel", the first argument to the watch callback can actually be a QIOChannel, which is not a GIOChannel (but a QEMU Object). Even though we never used that pointer, change the callback type to warn the users. Possibly a better fix later, we may want to store the callback and call it from intermediary functions.

2021-03-22hw/char: disable ibex uart receive if the buffer is fullAlexander Wagner1-5/+18
Not disabling the UART leads to QEMU overwriting the UART receive buffer with the newest received byte. The rx_level variable is added to allow the use of the existing OpenTitan driver libraries.

2021-03-08clock: Add ClockEvent parameter to callbacksPeter Maydell1-2/+2
The Clock framework allows users to specify a callback which is called after the clock's period has been updated. Some users need to also have a callback which is called before the clock period is updated. As the first step in adding support for notifying Clock users on pre-update events, add an argument to the ClockCallback to specify what event is being notified, and add an argument to the various functions for registering a callback to specify which events are of interest to that callback. Note that the documentation update renders correct the previously incorrect claim in 'Adding a new clock' that callbacks "will be explained in a following section".
