once with a list of all found devices. This lets us batch calls to MAKEDEV
which results in a noticeable improvement in Raspberry Pi boot time.
Run the initial device enumeration hooks before detaching from the foreground,
ensuring that any required devices have been created before the rc.d script
exits.
the Linux 2.6 TCP API. This permits the caller to query certain information
about a TCP connection, and is used by pkgsrc's net/iperf3 test program
if available.
This extends struct tcbcb with three fields to count retransmits,
out-of-sequence receives and zero window announcements, and will
therefore warrant a kernel revision bump (done separately).
move the swap code inside the loop.
'fs->fs_sbsize' is swapped twice: the first time in order to get the
correct superblock size, and later when swapping the whole superblock
structure. As a result, we need to check 'fs->fs_sbsize' twice.
This:
- fixes my previous changes for swapped FSes
- allows the kernel to look for other superblock locations if the
current superblock is not validated
And now:
- ffs_superblock_validate() takes only one argument: the fs structure
- 'fs_bsize' is unused, so delete it
Add some comments to explain a bit what we are doing.
superblock location may have changed. But that implies that we don't
handle the possibility that its size may have changed either.
Therefore: add a check to ensure the size hasn't changed. Otherwise the
mismatch leads to a memory corruption with kmem.
radeondrmkms on i386. the problem is that the pcdisplay@isa
and vga@isa drivers rely on some other driver having already
mapped the vga registers to know they should not attach, but
radeondrmkms attaches late as it needs rootfs access, and it
does not map these registers, and either of vga or pcdisplay
will attach, and then attach wsdisplay0, and then getty and
X11 will fail and you shake a tiny fist at the computer.
so, for i386, map and unmap the VGA register space between
the normal attach and the mountroot attach.
