  • bda0f5bad   tile: various console improvements ... Browse Code »

    This change improves and cleans up the tile console.

    - We enable HVC_IRQ support on tilegx, with the addition of a new
    Tilera hypervisor API for tilegx to allow a console IPI. If IPI
    support is not available we fall back to the previous polling mode.

    - We simplify the earlyprintk code to use CON_BOOT and eliminate some
    of the other supporting earlyprintk code.

    - A new tile_console_write() primitive is used to send output to
    the console and is factored out of the hvc_tile driver.
    This lets us support a "sim_console" boot argument to allow using
    simulator hooks to send output to the "console" as a slightly
    faster alternative to emulating the hardware more directly.

  • d0380e6c3   early_printk: consolidate random copies of identical code ... Browse Code »

    The early console implementations are the same all over the place. Move
    the print function to kernel/printk and get rid of the copies.

  • 0707ad30d   arch/tile: Miscellaneous cleanup changes. ... Browse Code »

    This commit is primarily changes caused by reviewing "sparse"
    and "checkpatch" output on our sources, so is somewhat noisy, since
    things like "printk() -> pr_err()" (or whatever) throughout the
    codebase tend to get tedious to read. Rather than trying to tease
    apart precisely which things changed due to which type of code
    review, this commit includes various cleanups in the code:

    - sparse: Add declarations in headers for globals.
    - sparse: Fix __user annotations.
    - sparse: Using gfp_t consistently instead of int.
    - sparse: removing functions not actually used.
    - checkpatch: Clean up printk() warnings by using pr_info(), etc.;
    also avoid partial-line printks except in bootup code.
    - checkpatch: Use exposed structs rather than typedefs.
    - checkpatch: Change some C99 comments to C89 comments.

    In addition, a couple of minor other changes are rolled in
    to this commit:

    - Add support for a "raise" instruction to cause SIGFPE, etc., to be raised.
    - Remove some compat code that is unnecessary when we fully eliminate
    some of the deprecated syscalls from the generic syscall ABI.
    - Update the tile_defconfig to reflect current config contents.

  • 867e359b9   arch/tile: core support for Tilera 32-bit chips. ... Browse Code »

    This change is the core kernel support for TILEPro and TILE64 chips.
    No driver support (except the console driver) is included yet.

    This includes the relevant Linux headers in asm/; the low-level
    low-level "Tile architecture" headers in arch/, which are
    shared with the hypervisor, etc., and are build-system agnostic;
    and the relevant hypervisor headers in hv/.
