Benoît Thébaudeau a52a3d94d3 cc2538: uart: Fix garbled output occurring upon lpm_enter()
lpm_enter() must not enter PM1+ if the UART is transmitting. Otherwise,
the UART clock gets disabled, and its TX is broken.

The commit b8b54a033c had already
partially fixed this issue, but it could still occur while transmitting
stop bits because, contrary to UART_FR.BUSY, UART_FR.TXFE takes only the
data bits into account, not the stop bits.

Michael LeMay bde8eb35ae x86, galileo: Fix UART system call authorization initialization
This patch fixes UART system call authorization initialization (when
protection domain support is enabled) to only initialize the system call
entrypoint and authorization data structures once, prior to per-port
setup. Previously, if two UARTs were configured, the setup procedure for
the second UART would erase the system call authorization for the
first (console) UART, resulting in a crash upon the next attempt to
perform console output.

George Oikonomou 8ab0522cec Fix PROP mode channel switching
If `NETSTACK_CONF_RADIO.set_value(RADIO_PARAM_CHANNEL, ...)` is called when radio is on, it will fail to apply the channel change, because it won't re-send `CMD_PROP_RADIO_DIV_SETUP` and `CMD_PROP_FS`. This commit fixes this condition, by making sure the correct commands are sent to the radio.

George Oikonomou 16f56abfad Wait for a valid RSSI reading in CC13xx/CC26xx RF drivers
As discussed in #1341, the current CC13xx/CC26xx IEEE mode driver sends `CMD_GET_RSSI` once and returns the RSSI reading uncondtionally. This happens within the `get_rssi()` function.

This logic is broken if `get_rssi()` is called with the radio off. The function will make sure to turn on the radio first, but it does not make sure the RSSI reading is valid, which only happens a number of symbol periods after the radio enters RX. The outcome is that `NETSTACK_RADIO.get_value(RADIO_PARAM_RSSI, ...)` will always return -128 (meaning that RSSI is unavailable) if the radio was off at the time of calling the function.

The same condition affects the prop mode driver.

This commit changes the logic of `get_rssi()`:
* For PROP mode, if `CMD_GET_RSSI` returns an invalid RSSI, we send it again. For unknown reasons, `CMD_GET_RSSI` on occasion returns 0, so we ignore that value too.
* For IEEE mode, we use `CMD_IEEE_CCA_REQ` and we inspect the value of `ccaInfo.ccaEnergy` of the return structure. If the value is 0x02 (Invalid), we send the command again.

Fixes #1341

George Oikonomou 568973f6ec Don't flush the CC2538 RF RX FIFO unconditionally
After reading a frame, `read()` checks the status of the RX FIFO:

* If an overflow is detected, the FIFO gets flushed
* If there are more frames in the FIFO, the `cc2538_rf_process` will get polled again in order to read out the next frame.

#1550 changed `read()`, which now performs the above check for non-poll mode, but it then flushes the FIFO unconditionally. Therefore, if there are two or more frames in the FIFO, they will get flushed before the `cc2538_rf_process` has had a chance to read them out. This results in missed frames.

Reproducing this is trivial: Build a CC2538 sniffer and see how it will never show you .15.4 ACK frames. ACK reception completes while `read()` is still streaming the previous captured frame to the host. Upon completion, the FIFO will get flushed and the ACK will get lost.

This pull proposes removing the unconditional flush and reverting to the original logic for non-TSCH operation.

Pinging @thomas-ha here for input regarding poll mode.

Benoît Thébaudeau 1da00a482f cc2538: aes: Fix possibly missing result available status
Depending on the use case and on the timings,
aes_auth_crypt_check_status() sometimes never reported an available
result, leading to a deadlock of any protothread waiting for this event,
and to a WDT reset if a protothread was polling it.

This was caused by aes_auth_crypt_start() clearing the result available
interrupt after operations that may rightfully trigger it, leading to a
missed interrupt.

George Oikonomou cd5a0ef291 Consolidate .upload for all CC26xx/CC13xx boards
The block that controls the `.upload` target is unnecessarily replicated in multiple sub-board Makefiles. This was originally done because the SmartRF and the Launchpad can be programmed with the c2538-bsl script, whereas the sensortag cannot.

This commit moves the `cc2538-bsl` / `.upload` target logic to the top level cpu Makefile (`cpu/cc26xx-cc13xx/Makefile.cc26xx-cc13xx`). Board makefiles simply set the make variable `BOARD_SUPPORTS_BSL` to 1 to signal that they can be programmed by the BSL script. If `BOARD_SUPPORTS_BSL` is not equal to 1, trying to use the `.upload` target will return an error message.

For example:

```
$ make BOARD=sensortag/cc2650 cc26xx-demo.upload
using saved target 'srf06-cc26xx'
This board cannot be programmed with the ROM bootloader and therefore does not support the .upload target.

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
