Michael LeMay 73774def6b x86, galileo: Add sample non-driver protection domain 
This patch adds a simple non-driver protection domain sample to serve
as an example for defining other non-driver protection domains.  It
simply performs a ping-pong test of protection domain switching
latency during boot, including optional accesses to a private metadata
region, and prints out the results.

Michael LeMay e0aefd11d9 x86: Add support for SW-switched segment-based protection domains 
This patch extends the protection domain framework with a third plugin
that is a hybrid of the previous two.  The hardware task switching
mechanism has a strictly-defined format for TSS data structures that
causes more space to be consumed than would otherwise be required.
This patch defines a smaller data structure that is allocated for each
protection domain, only requiring 32 bytes instead of 128 bytes.  It
uses the same multi-segment memory layout as the TSS-based plugin and
leaves paging disabled.  However, it uses a similar mechanism as the
paging plugin to perform system call dispatches and returns.

For additional information, please refer to cpu/x86/mm/README.md.

Michael LeMay 4cdb7ba9b6 x86: Add TSS-based protection domain support 
This patch extends the protection domain framework with an additional
plugin to use Task-State Segment (TSS) structures to offload much of
the work of switching protection domains to the CPU.  This can save
space compared to paging, since paging requires two 4KiB page tables
and one 32-byte page table plus one whole-system TSS and an additional
32-byte data structure for each protection domain, whereas the
approach implemented by this patch just requires a 128-byte data
structure for each protection domain.  Only a small number of
protection domains will typically be used, so
n * 128 < 8328 + (n * 32).

For additional information, please refer to cpu/x86/mm/README.md.

GCC 6 is introducing named address spaces for the FS and GS segments
[1].  LLVM Clang also provides address spaces for the FS and GS
segments [2].  This patch also adds support to the multi-segment X86
memory management subsystem for using these features instead of inline
assembly blocks, which enables type checking to detect some address
space mismatches.

Phil Rhinehart 5d5544151f Fixed bug in cc26xx-cc13xx rf-core. When running BLE in conjunction with ContikiMAC, oscillators were modified from an interrupt state causing occasional bus faults and infinite loops. We now check if BLE is active prior to modifiying the oscillators to avoid these conditions. 2016-04-18 17:17:07 +08:00
Phil Rhinehart 2a07dc0e0a This fixes an event handling issue in the cc26xx BLE driver. Currently, the rf_ble_beacon_process triggers the BLE beacon upon receiving any event, rather than verifying that the event timer has expired. This means that any PROCESS_BROADCAST (e.g. any sensor event) will fire the beacon. This commit adds logic to prevent this. 2016-04-18 17:14:37 +08:00
