These syscalls are a\npretty straightforward combination of pread and readv (same for write).\nThey are quite useful for doing vectored I/O in threaded applications.\nUsing lseek+readv instead opens race windows you\u0027ll have to plug with\nlocking.\n\nOther systems have such system calls too, for example NetBSD, check\nhere: http://www.daemon-systems.org/man/preadv.2.html\n\nThe application-visible interface provided by glibc should look like\nthis to be compatible to the existing implementations in the *BSD family:\n\n ssize_t preadv(int d, const struct iovec *iov, int iovcnt, off_t offset);\n ssize_t pwritev(int d, const struct iovec *iov, int iovcnt, off_t offset);\n\nThis prototype has one problem though: On 32bit archs is the (64bit)\noffset argument unaligned, which the syscall ABI of several archs doesn\u0027t\nallow to do. At least s390 needs a wrapper in glibc to handle this. As\nwe\u0027ll need a wrappers in glibc anyway I\u0027ve decided to push problem to\nglibc entriely and use a syscall prototype which works without\narch-specific wrappers inside the kernel: The offset argument is\nexplicitly splitted into two 32bit values.\n\nThe patch sports the actual system call implementation and the windup in\nthe x86 system call tables.

Actually, in this case, BAR 2 is the 3rd serial\nport while the parallel port is at BAR 4.\n\nI fixed 9845 1P4S and 9855 1P4S support, while preserving 9855 2P2S support,\n\n- by creating a netmos_9855_2p entry and using it for 9855 boards with 2\n parallel ports : 9855 2P2S and 9855 2P0S boards,\n\n- and by allowing netmos_parallel_init to change not only the number of\n parallel ports (0 or 1), but making it also change the BAR index of the\n parallel port when the serial ports are before the parallel port.\n\nPS: the netmos_9855_2p entry in (struct pciserial_board)\npci_parport_serial_boards[] is needed because netmos_parallel_init has no\nclean way to replace FL_BASE2 by FL_BASE4 in the description of the serial\nports in function of the number of parallel ports on the card.\n\nTested with 9845 1P4S, 9855 1P4S and 9855 2P2S boards.\n\nSigned-off-by: Philippe De Muyter \u003cphdm@macqel.be\u003e\nTested-by: Christian Pellegrin
