scftorture: Count single_rpc offline failures in statistics outputgrafted
scf_torture_stats_print() aggregates each invoker thread's counters
into a local scf_statistics structure before printing, but the
n_single_rpc_ofl field is missing from the aggregation loop. As a
result, the "single_rpc_ofl" value printed in the statistics line is
always zero, even when smp_call_function_single() invocations for the
RPC test have failed due to offline CPUs and been counted by the
invoker threads.
Add the missing accumulation so that the printed value reflects the
actual counts.

Since I do not have any datasheet or other + * documentation, inaccuracies are almost guaranteed. + * + * Some specs for the ARK3116 can be found here: + * http://web.archive.org/web/20060318000438/ + * www.arkmicro.com/en/products/view.php?id=10 + * On that page, 2 GPIO pins are mentioned: I assume these are the + * OUT1 and OUT2 pins of the UART, so I added support for those + * through the MCR. Since the pins are not available on my hardware, + * I could not verify this. + * Also, it states there is "on-chip hardware flow control". I have + * discovered how to enable that. Unfortunately, I do not know how to + * enable XON/XOFF (software) flow control, which would need support + * from the chip as well to work. Because of the wording on the web + * page there is a real possibility the chip simply does not support + * software flow control. + * + * I got my ark3116 as part of a mobile phone adapter cable. On the + * PCB, the following numbered contacts are present: + * + * 1:- +5V + * 2:o DTR + * 3:i RX + * 4:i DCD + * 5:o RTS + * 6:o TX + * 7:i RI + * 8:i DSR + * 10:- 0V + * 11:i CTS + * + * On my chip, all signals seem to be 3.3V, but 5V tolerant. But that + * may be different for the one you have ;-). + * + * The windows driver limits the registers to 0-F, so I assume there + * are actually 16 present on the device. + * + * On an UART interrupt, 4 bytes of data come in on the interrupt + * endpoint. The bytes are 0xe8 IIR LSR MSR. + * + * The baudrate seems to be generated from the 12MHz crystal, using + * 4-times subsampling. So quot=12e6/(4*baud). Also see description + * of register E. + * + * Registers 0-7: + * These seem to be the same as for a regular 16450. The FCR is set + * to UART_FCR_DMA_SELECT (0x8), I guess to enable transfers between + * the UART and the USB bridge/DMA engine. + * + * Register 8: + * By trial and error, I found out that bit 0 enables hardware CTS, + * stopping TX when CTS is +5V. Bit 1 does the same for RTS, making + * RTS +5V when the 3116 cannot transfer the data to the USB bus + * (verified by disabling the reading URB). Note that as far as I can + * tell, the windows driver does NOT use this, so there might be some + * hardware bug or something. + * + * According to a patch provided here + * https://lore.kernel.org/lkml/200907261419.50702.linux@rainbow-software.org + * the ARK3116 can also be used as an IrDA dongle. Since I do not have + * such a thing, I could not investigate that aspect. However, I can + * speculate ;-). + * + * - IrDA encodes data differently than RS232. Most likely, one of + * the bits in registers 9..E enables the IR ENDEC (encoder/decoder). + * - Depending on the IR transceiver, the input and output need to be + * inverted, so there are probably bits for that as well. + * - IrDA is half-duplex, so there should be a bit for selecting that. + * + * This still leaves at least two registers unaccounted for. Perhaps + * The chip can do XON/XOFF or CRC in HW? + * + * Register 9: + * Set to 0x00 for IrDA, when the baudrate is initialised. + * + * Register A: + * Set to 0x01 for IrDA, at init. + * + * Register B: + * Set to 0x01 for IrDA, 0x00 for RS232, at init. + * + * Register C: + * Set to 00 for IrDA, at init. + * + * Register D: + * Set to 0x41 for IrDA, at init. + * + * Register E: + * Somekind of baudrate override. The windows driver seems to set + * this to 0x00 for normal baudrates, 0x01 for 460800, 0x02 for 921600. + * Since 460800 and 921600 cannot be obtained by dividing 3MHz by an integer, + * it could be somekind of subdivisor thingy. + * However,it does not seem to do anything: selecting 921600 (divisor 3, + * reg E=2), still gets 1 MHz. I also checked if registers 9, C or F would + * work, but they don't. + * + * Register F: unknown + */ diff --git a/drivers/usb/serial/belkin_sa.c b/drivers/usb/serial/belkin_sa.c new file mode 100644 index 000000000..cfff29263 --- /dev/null +++ b/drivers/usb/serial/belkin_sa.c @@ -0,0 +1,481 @@ +// SPDX-License-Identifier: GPL-2.0+ +/* + * Belkin USB Serial Adapter Driver + * + * Copyright (C) 2000 William Greathouse (wgreathouse@smva.com) + * Copyright (C) 2000-2001 Greg Kroah-Hartman (greg@kroah.com) + * Copyright (C) 2010 Johan Hovold (jhovold@gmail.com) + * + * This program is largely derived from work by the linux-usb group + * and associated source files.

To + * identify the USB vendor-specific requests and to assign them to terminal + * settings (flow control, baud rate, etc.) the program "SerialSettings" from + * William G. Greathouse has been proven to be very useful. I also used the + * Win98 "HyperTerminal" and "usb-robot" on Linux for testing. The results and + * observations are summarized below: + * + * The USB requests seem to be directly mapped to the registers of a 8250, + * 16450 or 16550 UART. The FreeBSD handbook (appendix F.4 "Input/Output + * devices") contains a comprehensive description of UARTs and its registers. + * The bit descriptions are actually taken from there. + * + * + * Baud rate (divisor) + * ------------------- + * + * BmRequestType: 0x40 (0100 0000B) + * bRequest: 0x05 + * wValue: 0x0000 + * wIndex: 0x0000 + * wLength: 0x0004 + * Data: divisor = 115200 / baud_rate + * + * SniffUSB observations (Nov 2003): Contrary to the 'wLength' value of 4 + * shown above, observations with a Belkin F5U109 adapter, using the + * MCT-supplied Windows98 driver (U2SPORT.VXD, "File version: 1.21P.0104 for + * Win98/Me"), show this request has a length of 1 byte, presumably because + * of the fact that the Belkin adapter and the 'Sitecom U232-P25' adapter + * use a baud-rate code instead of a conventional RS-232 baud rate divisor. + * The current source code for this driver does not reflect this fact, but + * the driver works fine with this adapter/driver combination nonetheless. + * + * + * Line Control Register (LCR) + * --------------------------- + * + * BmRequestType: 0x40 (0100 0000B) 0xc0 (1100 0000B) + * bRequest: 0x07 0x06 + * wValue: 0x0000 + * wIndex: 0x0000 + * wLength: 0x0001 + * Data: LCR (see below) + * + * Bit 7: Divisor Latch Access Bit (DLAB). When set, access to the data + * transmit/receive register (THR/RBR) and the Interrupt Enable Register + * (IER) is disabled. Any access to these ports is now redirected to the + * Divisor Latch Registers. Setting this bit, loading the Divisor + * Registers, and clearing DLAB should be done with interrupts disabled. + * Bit 6: Set Break. When set to "1", the transmitter begins to transmit + * continuous Spacing until this bit is set to "0". This overrides any + * bits of characters that are being transmitted. + * Bit 5: Stick Parity. When parity is enabled, setting this bit causes parity + * to always be "1" or "0", based on the value of Bit 4. + * Bit 4: Even Parity Select (EPS). When parity is enabled and Bit 5 is "0", + * setting this bit causes even parity to be transmitted and expected. + * Otherwise, odd parity is used. + * Bit 3: Parity Enable (PEN). When set to "1", a parity bit is inserted + * between the last bit of the data and the Stop Bit. The UART will also + * expect parity to be present in the received data. + * Bit 2: Number of Stop Bits (STB). If set to "1" and using 5-bit data words, + * 1.5 Stop Bits are transmitted and expected in each data word. For + * 6, 7 and 8-bit data words, 2 Stop Bits are transmitted and expected. + * When this bit is set to "0", one Stop Bit is used on each data word. + * Bit 1: Word Length Select Bit #1 (WLSB1) + * Bit 0: Word Length Select Bit #0 (WLSB0) + * Together these bits specify the number of bits in each data word. + * 1 0 Word Length + * 0 0 5 Data Bits + * 0 1 6 Data Bits + * 1 0 7 Data Bits + * 1 1 8 Data Bits + * + * SniffUSB observations: Bit 7 seems not to be used. There seem to be two bugs + * in the Win98 driver: the break does not work (bit 6 is not asserted) and the + * stick parity bit is not cleared when set once. The LCR can also be read + * back with USB request 6 but this has never been observed with SniffUSB. + * + * + * Modem Control Register (MCR) + * ---------------------------- + * + * BmRequestType: 0x40 (0100 0000B) + * bRequest: 0x0a + * wValue: 0x0000 + * wIndex: 0x0000 + * wLength: 0x0001 + * Data: MCR (Bit 4..7, see below) + * + * Bit 7: Reserved, always 0. + * Bit 6: Reserved, always 0. + * Bit 5: Reserved, always 0. + * Bit 4: Loop-Back Enable. When set to "1", the UART transmitter and receiver + * are internally connected together to allow diagnostic operations. In + * addition, the UART modem control outputs are connected to the UART + * modem control inputs. CTS is connected to RTS, DTR is connected to + * DSR, OUT1 is connected to RI, and OUT 2 is connected to DCD. + * Bit 3: OUT 2. An auxiliary output that the host processor may set high or + * low. In the IBM PC serial adapter (and most clones), OUT 2 is used + * to tri-state (disable) the interrupt signal from the + * 8250/16450/16550 UART. + * Bit 2: OUT 1. An auxiliary output that the host processor may set high or + * low. This output is not used on the IBM PC serial adapter. + * Bit 1: Request to Send (RTS). When set to "1", the output of the UART -RTS + * line is Low (Active). + * Bit 0: Data Terminal Ready (DTR). When set to "1", the output of the UART + * -DTR line is Low (Active). + * + * SniffUSB observations: Bit 2 and 4 seem not to be used but bit 3 has been + * seen _always_ set. + * + * + * Modem Status Register (MSR) + * --------------------------- + * + * BmRequestType: 0xc0 (1100 0000B) + * bRequest: 0x02 + * wValue: 0x0000 + * wIndex: 0x0000 + * wLength: 0x0001 + * Data: MSR (see below) + * + * Bit 7: Data Carrier Detect (CD). Reflects the state of the DCD line on the + * UART. + * Bit 6: Ring Indicator (RI). Reflects the state of the RI line on the UART. + * Bit 5: Data Set Ready (DSR). Reflects the state of the DSR line on the UART. + * Bit 4: Clear To Send (CTS). Reflects the state of the CTS line on the UART. + * Bit 3: Delta Data Carrier Detect (DDCD). Set to "1" if the -DCD line has + * changed state one more more times since the last time the MSR was + * read by the host. + * Bit 2: Trailing Edge Ring Indicator (TERI). Set to "1" if the -RI line has + * had a low to high transition since the last time the MSR was read by + * the host. + * Bit 1: Delta Data Set Ready (DDSR). Set to "1" if the -DSR line has changed + * state one more more times since the last time the MSR was read by the + * host. + * Bit 0: Delta Clear To Send (DCTS). Set to "1" if the -CTS line has changed + * state one more times since the last time the MSR was read by the + * host. + * + * SniffUSB observations: the MSR is also returned as first byte on the + * interrupt-in endpoint 0x83 to signal changes of modem status lines. The USB + * request to read MSR cannot be applied during normal device operation. + * + * + * Line Status Register (LSR) + * -------------------------- + * + * Bit 7 Error in Receiver FIFO. On the 8250/16450 UART, this bit is zero. + * This bit is set to "1" when any of the bytes in the FIFO have one + * or more of the following error conditions: PE, FE, or BI. + * Bit 6 Transmitter Empty (TEMT). When set to "1", there are no words + * remaining in the transmit FIFO or the transmit shift register. The + * transmitter is completely idle. + * Bit 5 Transmitter Holding Register Empty (THRE). When set to "1", the + * FIFO (or holding register) now has room for at least one additional + * word to transmit. The transmitter may still be transmitting when + * this bit is set to "1". + * Bit 4 Break Interrupt (BI). The receiver has detected a Break signal. + * Bit 3 Framing Error (FE). A Start Bit was detected but the Stop Bit did + * not appear at the expected time. The received word is probably + * garbled. + * Bit 2 Parity Error (PE). The parity bit was incorrect for the word + * received. + * Bit 1 Overrun Error (OE). A new word was received and there was no room + * in the receive buffer. The newly-arrived word in the shift register + * is discarded. On 8250/16450 UARTs, the word in the holding register + * is discarded and the newly- arrived word is put in the holding + * register. + * Bit 0 Data Ready (DR). One or more words are in the receive FIFO that the + * host may read. A word must be completely received and moved from + * the shift register into the FIFO (or holding register for + * 8250/16450 designs) before this bit is set. + * + * SniffUSB observations: the LSR is returned as second byte on the + * interrupt-in endpoint 0x83 to signal error conditions. Such errors have + * been seen with minicom/zmodem transfers (CRC errors). + * + * + * Unknown #1 + * ------------------- + * + * BmRequestType: 0x40 (0100 0000B) + * bRequest: 0x0b + * wValue: 0x0000 + * wIndex: 0x0000 + * wLength: 0x0001 + * Data: 0x00 + * + * SniffUSB observations (Nov 2003): With the MCT-supplied Windows98 driver + * (U2SPORT.VXD, "File version: 1.21P.0104 for Win98/Me"), this request + * occurs immediately after a "Baud rate (divisor)" message.

It is unclear what purpose this message + * serves. + * + * + * Unknown #2 + * ------------------- + * + * BmRequestType: 0x40 (0100 0000B) + * bRequest: 0x0c + * wValue: 0x0000 + * wIndex: 0x0000 + * wLength: 0x0001 + * Data: 0x00 + * + * SniffUSB observations (Nov 2003): With the MCT-supplied Windows98 driver + * (U2SPORT.VXD, "File version: 1.21P.0104 for Win98/Me"), this request + * occurs immediately after the 'Unknown #1' message (see above). It was + * not observed at any other time. It is unclear what other purpose (if + * any) this message might serve, but without it, the USB/RS-232 adapter + * will not write to RS-232 devices which do not assert the 'CTS' signal. + * + * + * Flow control + * ------------ + * + * SniffUSB observations: no flow control specific requests have been realized + * apart from DTR/RTS settings. Both signals are dropped for no flow control + * but asserted for hardware or software flow control. + * + * + * Endpoint usage + * -------------- + * + * SniffUSB observations: the bulk-out endpoint 0x1 and interrupt-in endpoint + * 0x81 is used to transmit and receive characters. The second interrupt-in + * endpoint 0x83 signals exceptional conditions like modem line changes and + * errors. The first byte returned is the MSR and the second byte the LSR. + * + * + * Other observations + * ------------------ + * + * Queued bulk transfers like used in visor.c did not work. + * + * + * Properties of the USB device used (as found in /var/log/messages) + * ----------------------------------------------------------------- + * + * Manufacturer: MCT Corporation. + * Product: USB-232 Interfact Controller + * SerialNumber: U2S22050 + * + * Length = 18 + * DescriptorType = 01 + * USB version = 1.00 + * Vendor:Product = 0711:0210 + * MaxPacketSize0 = 8 + * NumConfigurations = 1 + * Device version = 1.02 + * Device Class:SubClass:Protocol = 00:00:00 + * Per-interface classes + * Configuration: + * bLength = 9 + * bDescriptorType = 02 + * wTotalLength = 0027 + * bNumInterfaces = 01 + * bConfigurationValue = 01 + * iConfiguration = 00 + * bmAttributes = c0 + * MaxPower = 100mA + * + * Interface: 0 + * Alternate Setting: 0 + * bLength = 9 + * bDescriptorType = 04 + * bInterfaceNumber = 00 + * bAlternateSetting = 00 + * bNumEndpoints = 03 + * bInterface Class:SubClass:Protocol = 00:00:00 + * iInterface = 00 + * Endpoint: + * bLength = 7 + * bDescriptorType = 05 + * bEndpointAddress = 81 (in) + * bmAttributes = 03 (Interrupt) + * wMaxPacketSize = 0040 + * bInterval = 02 + * Endpoint: + * bLength = 7 + * bDescriptorType = 05 + * bEndpointAddress = 01 (out) + * bmAttributes = 02 (Bulk) + * wMaxPacketSize = 0040 + * bInterval = 00 + * Endpoint: + * bLength = 7 + * bDescriptorType = 05 + * bEndpointAddress = 83 (in) + * bmAttributes = 03 (Interrupt) + * wMaxPacketSize = 0002 + * bInterval = 02 + * + * + * Hardware details (added by Martin Hamilton, 2001/12/06) + * ----------------------------------------------------------------- + * + * This info was gleaned from opening a Belkin F5U109 DB9 USB serial + * adaptor, which turns out to simply be a re-badged U232-P9.
