Currently we place efi boot binaries on to the 9fat and hope that the
firmware will look in more places than just the esp. Based on user
reports we've found that it is quite common for firmware to only
search the esp.
This is a kernel for the NXP LX2160A, specifically the SolidRun
Honeycomb board which is available for sale on the SolidRun
website.
It currently boots on U-Boot. UEFI support is planned. Build or
download the U-Boot firmware from the SolidRun site and then write
it to the on-board SD card. Then, plug in a USB with the honeycomb
image and proceed to install as normal. Only NVMe or USB storage
is supported (SATA is planned).
This kernel supports PCIe and USB. On-board ethernet and SFP are
not supported (yet). It uses 2GB of memory by default, but that
can be increased using *maxmem depending on how much RAM you have
in the system. As well, SMP is currently disabled until an
uncommon deadlock issue is fixed (could be a hardware issue, unknown
at this point).
we copied and pasted the structure of this from
cwfs, but they lay out the bits differently. We
fixed this for the other cases, but forgot this
one, which lead to exec being permitted when it
shouldn't have been.
in out of memory situations, clunkfid could run
out of memory and error; preallocating moves the
error to fscreate/fsopen, which are prepared to
handle them.
vertical scrolling now works in a line-wise manner,
just like in rio(1), sam(1) and friends. horizontal
scrolling showed problems with some line widths
where they got cut before showing the last
characters.
finally, pressing LMB or RMB and swiping while going
through any of the blocks caused a storm of plumbs
and visibility toggling (when over the expander line).
this doesn't happen anymore.
Currently we use millisecond ticks for time spent in each function.
This is not good enough for modern machines where fast functions could
be completed in a handful of nanoseconds. Instead let us just use the
raw ticks and store the cyclecfreq in the output prof data. This
requires that we enlargen the time section in the data to 8 bytes,
which broke the assumptions for struct allignment and required a
slight refactor of the code used to read it in prof(1). Since this is
a breaking change, we've devised a small format to communicate the
version for future revision of this format and this patch includes a
modification to file(1) for recognizing this format. Additionally
some minor improvements were made across the board.
When a function calls itself, the execution slot of its child is now
just added to its own time. This makes conceptual sense and also
reduces a big cause of depth inflation.
Current profiling size was 128k, and causes more frustration than it
is worth as demand paging makes this cheap. Assuming 64 bytes at
worst per Plink this will use ~16M of virtual address space on 64bit
systems.
