. vfs: 64-bit offset support for character device i/o
(also remove unused dev_bio function)
. memory: /dev/null and /dev/zero are infinitely large, don't stop
reading/writing at 4GB
one page at a time, and use safecopies to copy it to the requesting
process.
This lets /dev/mem access the entire physical address space, as the minix
page tables only allow access by default to physical RAM, which breaks
e.g. the VESA X driver in some cases.
. pci_reserve() returns an error on devices that have already been reserved,
instead of panic()ing; the pci_reserve() library call still panics,
pci_reserve_ok() returns an int.
. this allows at_wini to use the instance value as intended, as all devices
are seen, even reserved ones
. only devices actually used by at_wini are pci_reserve()d
. pci doesn't release devices based on argv[0], as at_wini both have the
same name and multiple instances won't work together properly
. include c1* nodes in std in MAKEDEV
. this requires a slightly larger shell
. this requires a larger blocksize on the boot ramdisk (to fit
/dev/ in direct blocks for mkfs with a proto file)
. also more inodes and kB's on the boot ramdisk
. replaced by a readclock 'driver' that runs once, a re-imported version
of the minix 2.0.4 readclock command.
. this has also restored cmos writing.
. readclock wrapper script calls service command to run /bin/readclock.drv
once.
libdriver. at_wini now queues messages it can't handle it receives when
waiting for an interrupt. this way it can do receive(ANY) and timeouts
should be working again (were broken for VFS, as with the advent of VFS,
at_wini could get requests from a filesystem while it was waiting for an
interrupt - as a hack, the receive() was changed to receive(HARDWARE)).
Added mq.c to libdriver, and made libdriver an actual library that
drivers link with -L../libdriver -ldriver. (So adding files, if
necessary, is easier next time.)
