For years I wondered why the floppy driver does not just work on sparc64, e.g: root@SUNW_375_0066:# disktype /dev/fd0 disktype: Can't open /dev/fd0: No such device or address [ 525.341906] disktype: attempt to access beyond end of device fd0: rw=0, sector=0, nr_sectors = 16 limit=8 [ 525.341991] floppy: error 10 while reading block 0 Turns out floppy.c __floppy_read_block_0 tries to read one page for the first test read to determine the disk size and thus fails if that is greater than 4k. Adjust minimum MAX_DISK_SIZE to PAGE_SIZE to fix floppy on sparc64 and likely all other PAGE_SIZE != 4KB configs.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
