patch to allow MINIX to boot from ext2.
To create a setup with MINIX on ext2, follow these steps:
- Assumptions:
- there exists a primary partition c0dApB with a MINIX installation
with GRUB support (/boot/image_latest exists on /dev/c0dApB)
- there exists a free primary partition c0dCpD
- Create an ext2 filesystem on c0dApB (from Linux, until Tthom
has ported mke2fs)
- Follow these steps (from a MINIX CD with ext2 support, another MINIX
installation (not c0dApB) or Linux >= 2.6.35):
mkdir /mnt/mfs /mnt/ext2
mount /dev/c0dApBs0 /mnt/mfs
mount /dev/c0dApBs1 /mnt/mfs/home
mount /dev/c0dApBs2 /mnt/mfs/usr
mount /dev/c0dCpD /mnt/ext2
synctree -f /mnt/mfs /mnt/ext2
echo root=/dev/c0dCpD > /mnt/ext2/etc/fstab
(note: no subpartitions used because that would confuse an unmodified
bootloader)
- Add the new MINIX installation to GRUB according to steps 7&8 in
http://wiki.minix3.org/en/SummerOfCode2010/MultiBoot/HowTo
This eliminates a race condition between the disk driver calling
sys_statectl(SYS_STATE_CLEAR_IPC_REFS) as part of driver_announce(),
and the root MFS calling sendrec(DEV_OPEN) on the disk driver.
-Makefile updates
-Update mkdep
-Build fixes/warning cleanups for some programs
-Restore leading underscores on global syms in kernel asm files
-Increase ramdisk size
model to an instance-based model. Each ethernet driver instance is now
responsible for exactly one network interface card. The port field in
/etc/inet.conf now acts as an instance field instead.
This patch also updates the data link protocol. This update:
- eliminates the concept of ports entirely;
- eliminates DL_GETNAME entirely;
- standardizes on using m_source for IPC and DL_ENDPT for safecopies;
- removes error codes from TASK/STAT replies, as they were unused;
- removes a number of other old or unused fields;
- names and renames a few other fields.
All ethernet drivers have been changed to:
- conform to the new protocol, and exactly that;
- take on an instance number based on a given "instance" argument;
- skip that number of PCI devices in probe iterations;
- use config tables and environment variables based on that number;
- no longer be limited to a predefined maximum of cards in any way;
- get rid of any leftover non-safecopy support and other ancient junk;
- have a correct banner protocol figure, or none at all.
Other changes:
* Inet.conf is now taken to be line-based, and supports #-comments.
No existing installations are expected to be affected by this.
* A new, select-based asynchio library replaces the old one.
Kindly contributed by Kees J. Bot.
* Inet now supports use of select() on IP devices.
Combined, the last two changes together speed up dhcpd
considerably in the presence of multiple interfaces.
* A small bug has been fixed in nonamed.
