Now that the CBM PFS supports file removal (and a file seek stub) it is possible to have the Telnet server leverage the IDE64 support of the CBM PFS.
Note: Using the CBM PFS for the Telnet server does _not_ reduce the code size since the POSIX I/O functions are additionally still linked in because the POSIX directory functions internally use the POSIX I/O functions. And that's the very reason why the CBM PFS is _not_ activated for the C128 Telnet server: The CBM PFS for the C128 doesn't bring IDE64 support but is supposed to be used to reduce code size - but this isn't possible for the Telnet server.
This is a fix for Contiki RPL so that it fully supports DAO ACK in
an end-to-end fashion. When DAO is sent it will be forwarded upwards
as before. DAO ACK will be forwarded downwards until it reach the node
that initiated the DAO ACK and unlike before it is not a single-hop
DAO ACK but it is fully reaching the RPL ROOT before any DAO ACK is
sent back. DAO ACK also now fully support different status messages
(success / fail).
This patch implements a simple, lightweight form of protection domains
using a pluggable framework. Currently, the following plugin is
available:
- Flat memory model with paging.
The overall goal of a protection domain implementation within this
framework is to define a set of resources that should be accessible to
each protection domain and to prevent that protection domain from
accessing other resources. The details of each implementation of
protection domains may differ substantially, but they should all be
guided by the principle of least privilege. However, that idealized
principle is balanced against the practical objectives of limiting the
number of relatively time-consuming context switches and minimizing
changes to existing code.
For additional information, please refer to cpu/x86/mm/README.md.
This patch also causes the C compiler to be used as the default linker
and assembler.
The UEFI GenFw program inserts headers ahead of the code in the UEFI
binary. The linker script adjusts the starting address of the .text
section to account for that. This prevents the symbols from being
perturbed. This patch accounts for a recent change in the size of the
headers added by the GenFw program.
This patch configures Isolated Memory Regions (IMRs) to block DMA to
code and data regions that do not contain any data that needs to be
DMA-accessible.
