* tty: n_hdlc, remove FILE and LINE from pr_debugJiri Slaby2020-03-161-21/+12
| | | | | | | | | | | | | As Joe suggests, dynamic debug can print module name and line number along with message. So remove __FILE__ and __LINE__ from all those pr_debug calls. Out of curiosity, I measured the savings, 200 bytes of code are gone.

| | | | | | | | | | | | | The merge commit cb05c6c82fb0 (Merge 5.6-rc5 into tty-next) introduced a double lock to set_selection_kernel. vc_sel.lock is locked both in set_selection_kernel and its callee __set_selection_kernel now.

* tty: serial: qcom_geni_serial: Don't try to manually disable the consoleDouglas Anderson2020-03-141-4/+0
| | | | | | | | | | | | | | | | | | The geni serial driver's shutdown code had a special case to call console_stop(). Grepping through the code, it was the only serial driver doing something like this (the only other caller of console_stop() was in serial_core.c). As far as I can tell there's no reason to call console_stop() in the geni code. ...and a good reason _not_ to call it. Specifically if you have an agetty running on the same serial port as the console then killing the agetty kills your console and if you start the agetty again the console doesn't come back.

* tty: serial: qcom_geni_serial: No need to stop tx/rx on UART shutdownDouglas Anderson2020-03-141-6/+0
| | | | | | | | | | | | | | | | | | | | On a board using qcom_geni_serial I found that I could no longer interact with kdb if I got a crash after the "agetty" running on the same serial port was killed. This meant that various classes of crashes that happened at reboot time were undebuggable. Reading through the code, I couldn't figure out why qcom_geni_serial felt the need to run so much code at port shutdown time. All we need to do is disable the interrupt. After I make this change then a hardcoded kgdb_breakpoint in some late shutdown code now allows me to interact with the debugger. I also could freely close / re-open the port without problems.

* vt: vt_ioctl: remove unnecessary console allocation checksEric Biggers2020-03-121-15/+1
| | | | | | | | | | | | | | | | The vc_cons_allocated() checks in vt_ioctl() and vt_compat_ioctl() are unnecessary because they can only be reached by calling ioctl() on an open tty, which implies the corresponding virtual console is allocated. And even if the virtual console *could* be freed concurrently, then these checks would be broken since they aren't done under console_lock, and the vc_data is dereferenced before them anyway. So, remove these unneeded checks to avoid confusion.

Yes, the idea probably was to allow '\0' in the sequence, but it's impractical: kernel configuration won't accept it to begin with followed by a comment about '\0' before comparison in question. Drop all these by switching to strlen() and convert code accordingly. Note, GCC seems clever enough to calculate string length at compile time.

| | | | | | | | | | | | | | | | | | To fix the RX cancel command failure, rx_fifo buffer needs to be flushed in stop_rx() by calling handle_rx().In handle_rx() the data in rx_fifo buffer is read and then dropped, not sent to upper layers. If set_termios is called before startup, by this time memory is not allocated to port->rx_fifo buffer, which leads to a NULL pointer dereference. To avoid this NULL pointer dereference allocate memory to port->rx_fifo in probe itself.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver for the Intel MID never seems to have been properly integrated upstream: the platform data in <linux/spi/ifx_modem.h> is not used anywhere in the kernel and haven't been since it was merged into the kernel in 2010. There might be out-of-tree users, so I don't want to delete the driver, but I will refactor it to use GPIO descriptors, which means that out-of-tree users will need to adapt. There are several examples in the kernel of how to provide the resources necessary for using GPIO descriptors to pass in the GPIO lines, for the MID platform in particular, it will suffice to inspect the code in files like: arch/x86/platform/intel-mid/device_libs/platform_bt.c This refactoring transfers all GPIOs in the driver, including a hard-coded "PMU reset" in the driver to use GPIO descriptors instead.

| | | | | | | | | | | | | | | | | | The DMA channel might not be available at probe time. This is esp. the case if the DMA controller has an IOMMU mapping. There is also another caveat. If there is no DMA controller at all, dma_request_chan() will also return -EPROBE_DEFER. Thus we cannot test for -EPROBE_DEFER in probe(). Otherwise the lpuart driver will fail to probe if, for example, the DMA driver is not enabled in the kernel configuration. To workaround this, we request the DMA channel in _startup(). Other serial drivers do it the same way.

* tty: sifive: Finish transmission before changing the clockPalmer Dabbelt2020-03-121-4/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SiFive's UART has a software controller clock divider that produces the final baud rate clock. Whenever the clock that drives the UART is changed this divider must be updated accordingly, and given that these two events are controlled by software they cannot be done atomically. During the period between updating the UART's driving clock and internal divider the UART will transmit a different baud rate than what the user has configured, which will probably result in a corrupted transmission stream. The SiFive UART has a FIFO, but due to an issue with the programming interface there is no way to directly determine when the UART has finished transmitting. We're essentially restricted to dead reckoning in order to figure that out: we can use the FIFO's TX busy register to figure out when the last frame has begun transmission and just delay for a long enough that the last frame is guaranteed to get out. As far as the actual implementation goes: I've modified the existing existing clock notifier function to drain both the FIFO and the shift register in on PRE_RATE_CHANGE. As far as I know there is no hardware flow control in this UART, so there's no good way to ask the other end to stop transmission while we can't receive (inserting software flow control messages seems like a bad idea here).
