*Nix and Win32 Kernel

Is this a problem?

2004-08-11 17:15 | *nix and Win32 Kernel

While reading the snapshot code in FFS Soft Updates’s FreeBSD implementation, I got a question about the following code:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
		/*
		 * If there is a fragment, clear it here.
		 */
		blkno = 0;
		loc = howmany(xp->i_size, fs->fs_bsize) - 1;
		if (loc < NDADDR) {
			__len = fragroundup(fs, blkoff(fs, xp->i\_size));__
			if (len < fs->fs_bsize) {
				ffs_blkfree(copy_fs, vp, DIP(xp, i_db[loc]),
				    len, xp->i_number);
				blkno = DIP(xp, i_db[loc]);
				DIP_SET(xp, i_db[loc], 0);
			}
		}

TLS(Thread Local Storage) is a vital part of thread support. Now FreeBSD have it, too!

Disabled Native Preemption on beastie

2004-07-31 05:26 | *nix and Win32 Kernel

I have decided to disable it as a workaround of the recent instablity of beastie, whose console I can’t easily touched. junsu has suggested this workaround and it seems to work :-(

I will install a local copy of delphijfork and figure out why it is stalling.

delphijfork 20040714

2004-07-15 05:37 | *nix and Win32 Kernel

As usual, it is available at ftp.freebsdchina.org/pub/china_ports/delphijfork.

This snapshot should be much more stable than previous one.

DragonFly to have 1.0-RELEASE

2004-07-13 06:52 | *nix and Win32 Kernel

Howard has set up a mirror for ISO.

Forked from FreeBSD 4-STABLE at a post-4.8 point, DragonFly is an excellent operating system adopting a different way 5-CURRENT has taken. Also, it was said to have the fastest TCP/IP stack in the world (With Jeffrey Hsu’s efforts, of course ;-) ).

Why hell there is livelock in idlepoll?

I have a preliminary discussion with junsu and we are still confused with the idlepoll livelock issue.

RFC 3522 implementation and Early Retransmission

2004-06-20 22:35 | *nix and Win32 Kernel

I have posted it as rev. 1.5 of <research.delphij.net/freebsd/rfc3522.diff>. Some minor comestic changes has gone into the patchset, as junsu pointed out. I’ll remove the unrelated ones soon.
