dry-runs are useful for warming up "hot paths" in UI code
to improve latency. This is specifically a feature for tuning
interactions on systems that have swap memory.
occassionally the hardware block just goes unresponsive. the
'fix' is to reset it, and then re-initialize the interface.
I suspect this has to do with the UDMA silently dropping transactions
when there's too much contention on the bus.
Previous implementation sent the QR code as draw commands.
This is inefficient as it would require hundreds of draw
commands to be sent per QR code rendered.
This implementation codes the QR code as a bool and sends
it in a single memory message, and implements a QR code renderer
on the receiver side.
The QR code rendering is also cleaned up so that the QR code is
always centered and takes the full screen, to give the best
conditions for someone scanning the code from another device.
the video layer is the "traffic cop" managing when modals
get focus. This patch creates a feed from the video layer
that listers to subscribe to that filters out key presses
destined for modals.
have to absorb a version change due to xous-semver change
might as well also update the utra/svd generator dependencies
since that's been held off for a long time now.
The code base had evolved through several code names, interim
names, company names and chip names that alternatively did or did
not exist.
Baochip is the definitive name of the company, and the Baochip1x
(full part number BAO1X2S4F-WA) is the definitivey part number of
the SoC. For convenience, the part number is shortened to 'bao1x'
in most feature flags and variable references.
This commit fixes all of the odd names and removes some unmaintained
early targets.
our implementantation of Buffer can't (currently) dynamically grow
the size of the object to serialize things that are bigger than
a page, so we have to enforce Vec-like objects to have a serialized
size of less than the page limit.
This is a bit of a moving target because it depends on implementation
specific details. A conservative bodge was put in to try and
work around this problem for now.
