Defining and using strtoul in lustre code results in the following compile warnings (arm64:allmodconfig). include/linux/libcfs/libcfs_string.h:105:0: warning: "strtoul" redefined #define strtoul(str, endp, base) simple_strtoul(str, endp, base) include/acpi/platform/aclinux.h:122:0: note: this is the location of the previous definition #define strtoul simple_strtoul Remove the definition and use simple_strtoul() directly. Note that we can not replace simple_strtoul with kstrtoul since the end pointer is used by the code. Signed-off-by:

This patch adds the core module of the MOST driver to the kernel's driver staging area. This module is part of the MOST driver and handles the configuration interface in sysfs, the buffer management and the data routing. MOST defines the protocol, hardware and software layers necessary to allow for the efficient and low-cost transport of control, real-time and packet data using a single medium (physical layer). Media currently in use are fiber optics, unshielded twisted pair cables (UTP) and coax cables. MOST also supports various speed grades up to 150 Mbps. For more information on MOST, visit the MOST Cooperation website: www.mostcooperation.com. Cars continue to evolve into sophisticated consumer electronics platforms, increasing the demand for reliable and simple solutions to support audio, video and data communications. MOST can be used to connect multiple consumer devices via optical or electrical physical layers directly to one another or in a network configuration. As a synchronous network, MOST provides excellent Quality of Service and seamless connectivity for audio/video streaming. Therefore, the driver perfectly fits to the mission of Automotive Grade Linux to create open source software solutions for automotive applications. The driver consists basically of three layers. The hardware layer, the core layer and the application layer. The core layer consists of the core module only. This module handles the communication flow through all three layers, the configuration of the driver, the configuration interface representation in sysfs, and the buffer management. For each of the other two layers a selection of modules is provided. These modules can arbitrarily be combined to meet the needs of the desired system architecture. A module of the hardware layer is referred to as an HDM (hardware dependent module). Each module of this layer handles exactly one of the peripheral interfaces of a network interface controller (e.g. USB, MediaLB, I2C). A module of the application layer is referred to as an AIM (application interfacing module). The modules of this layer give access to MOST via one the following ways: character devices, ALSA, Networking or V4L2. To physically access MOST, an Intelligent Network Interface Controller (INIC) is needed. For more information on available controllers visit: www.microchip.com Signed-off-by:

After IO partition recovery, it was possible to get into a situation where a visornic device would repeatedly report: NETDEV WATCHDOG: eth0 (): transmit queue 0 timed out The actual problem would affect any visornic device that was rapidly transmitting at the same time the IO partition was being recovered. Once you hit the problem, the only way to resume use of the nic would be to reboot the Linux client partition. The problem was caused by chstat.sent_xmit and chstat.got_xmit_done NOT getting cleared during IO partition recovery. This is necessary because outstanding xmits would essentially be "abandoned" during such recovery. These fields are now cleared in virtnic_serverdown_complete().

visornic tx reset handling is done asynchronously via a workqueue in visornic_timeout_reset(). As a result, it needs to use rtnl_lock() / rtnl_unlock() to lock against possible simultaneous close() of the network device. (I consulted the bnx2 driver as a model here, as that driver also does its tx reset handling asynchronously, just like visornic does. See bnx2_tx_timeout() and bnx2_reset_task().) Signed-off-by:

When s-Par is in polling mode it checks every 2 ms to see if there is a response from the IO service partition in the queue. Currently it just reads one entry per 2 ms, this needs to be changed so it drains the queue on each check. Signed-off-by:

The return value of the `cmdtest` handler for a subdevice checks the prospective new command in various steps and returns the step number at which any problem was detected, or 0 if no problem was detected. It is allowed to modify the command in various ways at each step. Corrections for out-of-range values are generally made at step 3, and minor adjustments such as rounding are generally made at step 4. The `cmdtest` handler for the AO subdevice (`usbduxsigma_ao_cmdtest()`) currently range checks the timings at step 3. Since the running command will round down the timings, add code to round them down at step 4. Signed-off-by:

The `cmdtest` and `cmd` handlers for the AO subdevice (`usbduxsigma_ao_cmdtest()` and `usbduxsigma_ao_cmd()`) support "scan" timing of commands with all channels updated every "scan" period. There is some disabled code to use "convert" timing in high speed mode. That would allow channels to be updated sequentially every "convert" period. Since that code is incomplete and currently disabled, remove it to simplify the existing code. Signed-off-by:

The `cmdtest` handler for the AI subdevice (`usbduxsigma_ai_cmdtest()`) currently modifies `cmd->scan_begin_arg` to bring it into range and round it down at step 3. Move the rounding down part to step 4 to follow the usual Comedi convention. Signed-off-by:

The AI subdevice `cmdtest` handler `usbduxsigma_ai_cmdtest()` ensures that `cmd->scan_begin_src == TRIG_TIMER` by the end of step 2 of the command checking code, so assume that this is the case for step 3 onwards and remove the redundant code. Signed-off-by:

`devpriv->ao_timer` is used while an asynchronous command is running on the AO subdevice. It also gets modified by the subdevice's `cmdtest` handler for checking new asynchronous commands, `usbduxsigma_ao_cmdtest()`, which is not correct as it's allowed to check new commands while an old command is still running. Fix it by moving the code which sets up `devpriv->ao_timer` into the subdevice's `cmd` handler, `usbduxsigma_ao_cmd()`. Note that the removed code in `usbduxsigma_ao_cmdtest()` checked that `devpriv->ao_timer` did not end up less that 1, but that could not happen due because `cmd->scan_begin_arg` or `cmd->convert_arg` had already been range-checked. Also note that we tested the `high_speed` variable in the old code, but that is currently always 0 and means that we always use "scan" timing (`cmd->scan_begin_src == TRIG_TIMER` and `cmd->convert_src == TRIG_NOW`) and never "convert" (individual sample) timing (`cmd->scan_begin_src == TRIG_FOLLOW` and `cmd->convert_src == TRIG_TIMER`). The moved code tests `cmd->convert_src` instead to decide whether "scan" or "convert" timing is being used, although currently only "scan" timing is supported.
