Re: [RFC] Unify KVM kernel-space and user-space code into a single project

2010-03-21T22:01:18Z

If that is the theory then it has failed to trickle through in practice. As
you know i have reported a long list of usability problems with hardly a look.
That list could be created by pretty much anyone spending a few minutes of
getting a first impression with qemu-kvm.
So something is seriously wrong in KVM land, to pretty much anyone trying it

Re: [PATCH] atmel_serial: Atmel RS485 support

2010-03-21T21:55:39Z

Ugh, not sure what happened to my previous email. It looked fine in
Thunderbird before I sent it. Hopefully this works a bit better:
This comment is misleading, it is a struct not a flag. The comment should
say that it is the rs485 settings for the uart.
Can you move these functions, so that these declarations are not needed?

I think this sums up the root cause of all the problems i see with KVM pretty
well.
Thanks,

Re: [PATCH] fix PHY polling system blocking

2010-03-21T21:54:36Z

I had now analyzed the PHY handling in most of the network drivers. Most
of the PHY communication will be handled in a polling/blocking way,
write a command word and then wait for the results. Due the nature of
the PHY attachment, this will take some time.
Some of the network drivers do this polling/blocking also in atomic code

1)
One of the primary design arguments of the micro-kernel design as well was to
push as much into user-space as possible without impacting performance too
much so you very much seem to be arguing for a micro-kernel design for the
kernel.
I think history has given us the answer for that fight between microkernels

Sorry, that was not the intent. I meant that putting things into the
kernel have disadvantages that must be considered.
I believe you can deploy this daemon via a (default) package, without
any hassle to users.

That would be shooting at my own foot as well as the contributor's since
I badly want that RCU stuff, and while a GUI would be nice, that itch
isn't on my back.
You're asking a developer and a maintainer to put off the work they're
interested in, in order to work on something someone else is interested

If you are ready to run Zaurus in dismantled state, then yes. Measure on

nearby (probably to the right).
Alternatively, it is possible to write a driver. It is just one byte

Please close it. I haven't seen this anymore and I'm now in 2.6.34-rc1 (March

I'm certainly a minimalist, but that doesn't follow. Things that
require privileged access, or access to the page cache, or that can't be
made to perform otherwise should certainly be in the kernel. That's why
I submitted kvm for inclusion in the first place.
If it's something that can work just as well in userspace but we can't

[PATCH] drivers/media/video: avoid NULL dereference

2010-03-21T21:31:17Z

If ov is NULL, it will not be possible to take the lock in the first place,
so move the test up earlier.
The semantic match that finds the problem is as follows:
([link])
// <smpl>
@r exists@
expression E, E1;
identifier f;
statement S1,S3;
iterator iter;
@@
if ((E == NULL && ...) || ...)

better/faster kernel tarball compression

Dear lkml Reader,
please allow me to spam you a bit with two compression programs.
I just downloaded the Linux 2.6.34-rc2 tarball:
