+ attempt to register only if we can stat() the devpath. this works
around e.g. nfs devpath, which is useless to register to etfs
XXX: the caller should decide
introduce a new and improved "etfs" interface, which can be used
to register host files accessible from rump fs namespace. This
new interface is not restriced to block devices, and neither does
it require the same pathname in host namespace and rump namespace.
Therefore, the same host file can be represented both as a char
and block device in rump namespace.
* adjust rumpblk to make the above possible
* improve rumpfs: nodes are now created properly and not implicitly
tied to the vnode lifecycle
the end of sdattach() to the end of sd_get_parms(). The code at
the bottom of sd_get_parms() was only used for optical drives or
in the case where the drive geometry couldn't be retrived for some
reason, to create a fake geometry. The case for setting up the
real geometry was handled above that code.
* Disable interrupts in otherwise-configure Nvidia graphics card
* Support genfb console, based on information supplied by the bootloader
* Support kernel args
* Support ways to choose which console to use
* Clarify argument parsing a little.
(from me and abs)
because we know how to configure all of the hardware, but as we don't know
how to configure the Iyonix graphics card we must rely on RISC OS to do
it for us.
While we're here, space separate the kernel arguments. It's a bit hard
parsing them in the kernel when they're all run together.
and vtime > 0. It should be allowed to go to sleep for the sleep interval
indicated in vtime. Reported by der Mouse a long while ago, and this is what
other unixes do.
Factor out common code of chroot-like syscalls into change_root() and export
that function for use in other parts of the kernel.
Rename change_dir() to chdir_lookup() as the latter describes better what
the function does. While there, move the namei_data initialisation into
chdir_lookup(), too. And export chdir_lookup().
Since 'rep stos' will have a long setup time, avoid doing it more than once.
For misaligned (start address or length) write an unaligned word at both
ends of the buffer then aligned 'rep stosd' the middle.
Use the same code for bzero().
bzero.S is left being compiled for a while (empty) - to avoid issues with
duplicate symbols in libc.a after update builds.
