* m-labs/master:
applets: compatibility with older Qt. Closes#629
doc: update LLVM configure command (fixes#628).
runtime: match argument signedness between ARTIQ Python and ksupport.
runtime: refactor rtio_output_list.
runtime: use correct ABI when accepting ARTIQ lists.
This is to support channels where variable length
event data is well-defined through zero-padding.
E.g. in the case of `Spline` zero-padding of events naturally
corresponds to low-order knots.
Use timestamp change as trigger. This assumes that writes to the
timestamp register always precede address and data writes.
It does not break support for ganged writes of the same event
timestamp and data/address to multiple channels or
channel-addresses.
* m-labs/master:
runtime: don't attempt to perform writeback if disabled in kernel.
runtime: print trace level log messages to UART during startup.
runtime: support for targets without RTIO log channel
runtime: support for targets without I2C
kc705: remove stale DDS definition
runtime: show a prompt to erase startup/idle kernels.
* phaser:
runtime: replace a (deliberate) memory leak with an interner.
compiler: disable remarks.
runtime: rewrite i2c support code in Rust.
runtime: rewrite rtio support code in Rust.
* master:
runtime: replace a (deliberate) memory leak with an interner.
compiler: disable remarks.
runtime: rewrite i2c support code in Rust.
runtime: rewrite rtio support code in Rust.
