When +UHD software detects the overflow, it prints an "O" or "D" to stdout, +and pushes an inline message packet into the receive stream. + +<b>Network-based devices</b>: The host does not back-pressure the receive +stream. When the kernel's socket buffer becomes full, it will drop +subsequent packets. UHD software detects the overflow as a discontinuity +in the packet's sequence numbers, and pushes an inline message packet +into the receive stream. In this case the character "D" is printed to +stdout as an indication. + +<b>Other devices</b>: The host back-pressures the receive stream. +Therefore, overflows always occur in the device itself. When the +device's internal buffers become full, streaming is shut off, and an +inline message packet is sent to the host. In this case the character +"O" is printed to stdout as an indication. If the device was in +continuous streaming mode, the UHD software will automatically restart +streaming when the buffer has space again. + +\subsection general_ounotes_underrun Underrun notes + +When transmitting, the device consumes samples at a constant rate. +Underflow occurs when the host does not produce data fast enough. When +UHD software detects the underflow, it prints a "U" to stdout, and +pushes a message packet into the async message stream. + +<b>Note:</b> "O" and "U" message are generally harmless, and just mean the host machine can't keep up with the requested rates. + +\section general_threading Threading Notes + +\subsection general_threading_safety Thread safety notes + +For the most part, UHD software is thread-safe. Please observe the +following limitations: + +<b>Fast-path thread requirements:</b> There are three fast-path methods for +a device: `send()`, `recv()`, and `recv_async_msg()`. All three +methods are thread-safe and can be called from different thread +contexts. For performance, the user should call each method from a +separate thread context. These methods can also be used in a +non-blocking fashion by using a timeout of zero. + +<b>Slow-path thread requirements:</b> It is safe to change multiple +settings simultaneously. However, this could leave the settings for a +device in an uncertain state. This is because changing one setting could +have an impact on how a call affects other settings. Example: setting +the channel mapping affects how the antennas are set. It is recommended +to use at most one thread context for manipulating device settings. + +\subsection general_threading_prio Thread priority scheduling + +When UHD software spawns a new thread it may try to boost the thread's +scheduling priority. When setting the priority fails, the UHD software +prints out an error. This error is harmless; it simply means that the +thread will have a normal scheduling priority. + +<b>Linux Notes:</b> + +Non-privileged users need special permission to change the scheduling +priority. Add the following line to `/etc/security/limits.conf`: + + @GROUP - rtprio 99 + +Replace `GROUP` with a group to which your user belongs. +Settings will not take effect until the user is in a different login +session. + +\section general_misc Miscellaneous Notes + +\subsection general_misc_dynamic Support for dynamically loadable modules + +For a module to be loaded at runtime, it must be: + +- found in the `UHD_MODULE_PATH` environment variable, +- installed into the `\<install-path\>/share/uhd/modules` directory, +- or installed into `/usr/share/uhd/modules` directory (UNIX only). + +\subsection general_misc_prints Disabling or redirecting prints to stdout + +The user can disable the UHD library from printing directly to stdout by +registering a custom message handler.

However, -this could leave the settings for a device in an uncertain state. -This is because changing one setting could have an impact on how a call affects other settings. -Example: setting the channel mapping affects how the antennas are set. -It is recommended to use at most one thread context for manipulating device settings. - -^^^^^^^^^^^^^^^^^^^^^^^^^^ -Thread priority scheduling -^^^^^^^^^^^^^^^^^^^^^^^^^^ - -When UHD software spawns a new thread it may try to boost the thread's scheduling priority. -When setting the priority fails, the UHD software prints out an error. -This error is harmless; it simply means that the thread will have a normal scheduling priority. - -**Linux Notes:** - -Non-privileged users need special permission to change the scheduling priority. -Add the following line to **/etc/security/limits.conf**: -:::::::::::::::::::::::::::::::::::::::::::::::::::::::: - - @<my_group> - rtprio 99 - -Replace **<my_group>** with a group to which your user belongs. -Settings will not take effect until the user is in a different login session. - -------------------- -Miscellaneous Notes -------------------- - -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -Support for dynamically loadable modules -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -For a module to be loaded at runtime, it must be: - -* found in the **UHD_MODULE_PATH** environment variable, -* installed into the **<install-path>/share/uhd/modules** directory, -* or installed into **/usr/share/uhd/modules** directory (UNIX only). - -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -Disabling or redirecting prints to stdout -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -The user can disable the UHD library from printing directly to stdout by registering a custom message handler. -The handler will intercept all messages, which can be dropped or redirected. -Only one handler can be registered at a time. -Make **register_handler** your first call into the UHD library: - -:: - - #include <uhd/utils/msg.hpp> - - void my_handler(uhd::msg::type_t type, const std::string &msg){ - //handle the message... - } - - uhd::msg::register_handler(&my_handler); diff --git a/host/docs/gpio_api.dox b/host/docs/gpio_api.dox new file mode 100644 index 000000000..17a2411fc --- /dev/null +++ b/host/docs/gpio_api.dox @@ -0,0 +1,119 @@ +/*! \page page_gpio_api X3x0 GPIO API + +\tableofcontents + +\section xgpio_fpanel The X3x0 Front Panel GPIO + +The X3x0 is the first USRP device to offer an auxiliary GPIO connection +on the motherboard itself (independent of the daughterboards).

These optional parameters control -how the transport object allocates memory, resizes kernel buffers, spawns -threads, etc. When not spcified, the transport layer will use values for these -parameters that are known to perform well on a variety of systems. The -transport parameters are defined below for the various transports in the UHD -software: - ------------------------------------------------------------------------- -UDP Transport (Sockets) ------------------------------------------------------------------------- -The UDP transport is implemented with user-space sockets. -This means standard Berkeley sockets API using send()/recv(). - -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -Transport parameters -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -The following parameters can be used to alter the transport's default behavior: - -* **recv_frame_size:** The size of a single receive buffer in bytes -* **num_recv_frames:** The number of receive buffers to allocate -* **send_frame_size:** The size of a single send buffer in bytes -* **num_send_frames:** The number of send buffers to allocate - -**Note1:** -**num_recv_frames** does not affect performance. - -**Note2:** -**num_send_frames** does not affect performance. - -**Note3:** -**recv_frame_size** and **send_frame_size** can be used to -increase or decrease the maximum number of samples per packet. -The frame sizes default to an MTU of 1472 bytes per IP/UDP packet -and may be increased if permitted by your network hardware. - -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -Flow control parameters -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -The host-based flow control expects periodic update packets from the device. -These update packets inform the host of the last packet consumed by the device, -which allows the host to determine throttling conditions for the transmission of packets. -The following mechanisms affect the transmission of periodic update packets: - -* **ups_per_fifo:** The number of update packets for each FIFO's worth of bytes sent into the device -* **ups_per_sec:** The number of update packets per second (defaults to 20 updates per second) - -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -Resize socket buffers -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -It may be useful to increase the size of the socket buffers to -move the burden of buffering samples into the kernel or to -buffer incoming samples faster than they can be processed. -However, if your application cannot process samples fast enough, -no amount of buffering can save you. -The following parameters can be used to alter socket's buffer sizes: - -* **recv_buff_size:** The desired size of the receive buffer in bytes -* **send_buff_size:** The desired size of the send buffer in bytes - -**Note:** Large send buffers tend to decrease transmit performance. - -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -Latency Optimization -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -Latency is a measurement of the time it takes a sample to travel between the host and device. -Most computer hardware and software is bandwidth optimized, which may negatively affect latency. -If your application has strict latency requirements, please consider the following notes: - -**Note1:** -The time taken by the device to populate a packet is proportional to the sample rate. -Therefore, to improve receive latency, configure the transport for a smaller frame size. - -**Note2:** -For overall latency improvements, -look for "Interrupt Coalescing" settings for your OS and ethernet chipset. -It seems the Intel ethernet chipsets offer fine-grained control in Linux. -Also, consult: - -* http://publib.boulder.ibm.com/infocenter/pseries/v5r3/index.jsp?topic=/com.ibm.aix.prftungd/doc/prftungd/interrupt_coal.htm - -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -Linux specific notes -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -On Linux, the maximum buffer sizes are capped by the sysctl values -**net.core.rmem_max** and **net.core.wmem_max**. -To change the maximum values, run the following commands: -:: - - sudo sysctl -w net.core.rmem_max=<new value> - sudo sysctl -w net.core.wmem_max=<new value> - -Set the values permanently by editing **/etc/sysctl.conf**. - -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -Windows specific notes -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -**UDP send fast-path:** -It is important to change the default UDP behavior such that -1500 byte packets still travel through the fast path of the sockets stack. -This can be adjusted with the FastSendDatagramThreshold registry key: - -* FastSendDatagramThreshold registry key documented here: - - * http://www.microsoft.com/windows/windowsmedia/howto/articles/optimize_web.aspx#appendix_e - -* Double click and run <install-path>/share/uhd/FastSendDatagramThreshold.reg -* A system reboot is recommended after the registry key change. - -**Power profile:** -The Windows power profile can seriously impact instantaneous bandwidth. -Application can take time to ramp-up to full performance capability. -It is recommended that users set the power profile to "high performance". - ------------------------------------------------------------------------- -USB Transport (LibUSB) ------------------------------------------------------------------------- -The USB transport is implemented with LibUSB. -LibUSB provides an asynchronous API for USB bulk transfers. - -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -Transport parameters -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -The following parameters can be used to alter the transport's default behavior: - -* **recv_frame_size:** The size of a single receive transfers in bytes -* **num_recv_frames:** The number of simultaneous receive transfers -* **send_frame_size:** The size of a single send transfers in bytes -* **num_send_frames:** The number of simultaneous send transfers - -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -Setup Udev for USB (Linux) -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -On Linux, Udev handles USB plug and unplug events. -The following commands install a Udev rule -so that non-root users may access the device: -

The following +tips are designed to help narrow down and diagnose the problem. + +\subsection usrp2_commprob_ctrlresponse RuntimeError: no control response + +This is a common error that occurs when you have set the subnet of your +network interface to a different subnet than the network interface of +the USRP device. For example, if your network interface is set to **192.168.20.1**, +and the USRP device is **192.168.10.2** (note the +difference in the third numbers of the IP addresses), you will likely +see a 'no control response' error message. + +Fixing this is simple - just set the your host PC's IP address to the +same subnet as that of your USRP device. Instructions for setting your +IP address are in the previous section of this documentation. + +\subsection usrp2_commprob_firewall Firewall issues + +When the IP address is not specified, the device discovery broadcasts +UDP packets from each ethernet interface. Many firewalls will block the +replies to these broadcast packets. If disabling your system's firewall +or specifying the IP address yields a discovered device, then your +firewall may be blocking replies to UDP broadcast packets. If this is +the case, we recommend that you disable the firewall or create a rule to +allow all incoming packets with UDP source port **49152**. + +\subsection usrp2_commprob_ping Ping the device + +The USRP device will reply to ICMP echo requests.
