  • 4f640efb3   Use resource_size_t for serial port IO addresses ... Browse Code »

    At present, various parts of the serial code use unsigned long to define
    resource addresses. This is a problem, because some 32-bit platforms have
    physical addresses larger than 32-bits, and have mmio serial uarts located
    above the 4GB point.

    This patch changes the type of mapbase in both struct uart_port and struct
    plat_serial8250_port to resource_size_t, which can be configured to be 64
    bits on such platforms. The mapbase in serial_struct can't safely be
    changed, because that structure is user visible.

  • 18a8bd949   serial: convert early_uart to earlycon for 8250 ... Browse Code »

    Beacuse SERIAL_PORT_DFNS is removed from include/asm-i386/serial.h and
    include/asm-x86_64/serial.h. the serial8250_ports need to be probed late in
    serial initializing stage. the console_init=>serial8250_console_init=>
    register_console=>serial8250_console_setup will return -ENDEV, and console
    ttyS0 can not be enabled at that time. need to wait till uart_add_one_port in
    drivers/serial/serial_core.c to call register_console to get console ttyS0.
    that is too late.

    Make early_uart to use early_param, so uart console can be used earlier. Make
    it to be bootconsole with CON_BOOT flag, so can use console handover feature.
    and it will switch to corresponding normal serial console automatically.

    new command line will be:
    console=uart8250,io,0x3f8,9600n8
    console=uart8250,mmio,0xff5e0000,115200n8
    or
    earlycon=uart8250,io,0x3f8,9600n8
    earlycon=uart8250,mmio,0xff5e0000,115200n8

    it will print in very early stage:
    Early serial console at I/O port 0x3f8 (options '9600n8')
    console [uart0] enabled
    later for console it will print:
    console handover: boot [uart0] -> real [ttyS0]

  • e0980dafa   [PATCH] Exar quad port serial ... Browse Code »

    This is on our "Envoy" boxes which we have, according to the documentation, an
    "Exar ST16C554/554D Quad UART with 16-byte Fifo's". The box also has two
    other "on-board" serial ports and a modem chip.

    The two on-board serial UARTs were being detected along with the first two
    Exar UARTs. The last two Exar UARTs were not showing up and neither was the
    modem.

    This patch was the only way I could the kernel to see beyond the standard four
    serial ports and get all four of the Exar UARTs to show up.

  • 0077d45e4   [SERIAL] Make uart_port flags a bitwise type ... Browse Code »

    Same reasoning as commit 747c8a55946ed037bf7d62454c3c599c02af2262
    but this time we're making uart_port flags a bitwise type - not
    all of these flags correspond with the old ASYNC_ flags, so there
    is the possibility for bugs if the wrong ASYNC_* constants are
    used. Always use UPF_* constants for uart_port->flags.

  • ec9f47cd6   [PATCH] Serial: Split 8250 port table ... Browse Code »

    Add separate files for the different 8250 ISA-based serial boards.

    Looking across all the various architectures, it seems reasonable that
    we can key the availability of the configuration options for these
    beasts to the bus-related symbols (iow, CONFIG_ISA). We also standardise
    the base baud/uart clock rate for these boards - I'm sure that isn't
    architecture specific, but is solely dependent on the crystal fitted
    on the board (which should be the same no matter what type of machine
    its fitted into.)

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
