  • 217bbd818   m68k/atari: Reserve some ST-RAM early on for device buffer use ... Browse Code »

    Based on an original patch from Michael Schmitz:

    Because mem_init() is now called before device init, devices that rely on
    ST-RAM may find all ST-RAM already allocated to other users by the time
    device init happens. In particular, a large initrd RAM disk may use up
    enough of ST-RAM to cause atari_stram_alloc() to resort to
    __get_dma_pages() allocation.

    In the current state of Atari memory management, all of RAM is marked
    DMA capable, so __get_dma_pages() may well return RAM that is not in actual
    fact DMA capable. Using this for frame buffer or SCSI DMA buffer causes
    subtle failure.

    The ST-RAM allocator has been changed to allocate memory from a pool of
    reserved ST-RAM of configurable size, set aside on ST-RAM init (i.e.
    before mem_init()). As long as this pool is not exhausted, allocation of
    real ST-RAM can be guaranteed.

    Other changes:
    - Replace the custom allocator in the ST-RAM pool by the existing allocator
    in the resource subsystem,
    - Remove mem_init_done and its hook, as memory init is now done before
    device init,
    - Remove /proc/stram, as ST-RAM usage now shows up under /proc/iomem, e.g.

    005f2000-006f1fff : ST-RAM Pool
    005f2000-0063dfff : atafb
    0063e000-00641fff : ataflop
    00642000-00642fff : SCSI

  • 7ae4833af   m68k: Define rtc_lock on Atari ... Browse Code »

    The nvram and rtc-cmos drivers use the spinlock rtc_lock to protect against
    concurrent accesses to the CMOS memory. As m68k doesn't support SMP or preempt
    yet, the spinlock calls tend to get optimized away, but not for all
    configurations, causing in some rare cases:

    | ERROR: "rtc_lock" [drivers/rtc/rtc-cmos.ko] undefined!
    | ERROR: "rtc_lock" [drivers/char/nvram.ko] undefined!

    Add the spinlock to the Atari core code to avoid this.

  • 72a7fe396   Introduce flags for reserve_bootmem() ... Browse Code »

    This patchset adds a flags variable to reserve_bootmem() and uses the
    BOOTMEM_EXCLUSIVE flag in crashkernel reservation code to detect collisions
    between crashkernel area and already used memory.

    This patch:

    Change the reserve_bootmem() function to accept a new flag BOOTMEM_EXCLUSIVE.
    If that flag is set, the function returns with -EBUSY if the memory already
    has been reserved in the past. This is to avoid conflicts.

    Because that code runs before SMP initialisation, there's no race condition
    inside reserve_bootmem_core().
