. An updated version of Russell's PCMCIA patches

. Lots more anticipatory scheduler work.

. It turns out that calling disk request_fns from timer/tasklet context is
  not permitted because a few old drivers like to sleep in that function. 

  keventd cannot be used for this because it can deadlock.  So another
  kernel thread per CPU has been reluctantly added.

Re: 2.5.65-mm1

[Helge Hafting]

2.5.65-mm1 seems to work fine on my up office machine.

Using devfs is no problem with debian unstable/testing.
No config files needed to be changed compared to "normal" devfs.
Three files needed changing compared to plain old  non-devfs:
/etc/fstab:   use /dev/discs/disc0/partX instead /dev/hdaX
/etc/gpm:     use mouse device /dev/input/mouse0 instead of /dev/psaux
/etc/inittab: Specify vc/X instead of ttyX for getty. X came up even
without this.

Re: 2.5.65-mm1 small nfs umount problem, also in 64-mm8

[Helge Hafting]

I have some nfs mounts that users are allowed to mount.
That works, but the user can't umount. "Only root can umount..."
I believe the user doing the mount were allowed to umount before.

Did you upgrade your util-linux package recently and do
you have /etc/mtab symlinked to /proc/mounts?

I noticed a similar problem (with user-mountable CD-ROM
devices and linux-kernel v2.2) and found a change in
util-linux/mount/umount.c which might be responsible for
it. If so, it is IMHO not a kernel issue, anyway

I didn't have the time to further examine the problem yet,
though...

I tried to get find what made 2.5.64-mm1 special that made my Radeon
card work, and had no luck in boiling down the differences more than
generally waving in the general direction "seems to be the PCI
updates". Nothing, up to and including 2.5.64-mm8, worked, but now
2.5.65-mm1 works like a charm and I'm on it now. I'll let you know if
it breaks again (or other breakage I find) :)

Oh well, I've had one hang within 10 minutes of booting, came back and
the machine was unresponsive (mouse and keyboard under X, unable to
switch to console). Apart from that I've got two funnies in my boot
messages:

PCI: Cannot allocate resource region 0 of device 02:0e.2

THe device is my USB hub in the laptop:

And this one when probing for my PCIC:

And related to the video trouble, I fond this in the bootlog:

With 2.4 I used 4x AGP with X with no hassle.

Could you send the full bus information for all devices (lspci -vv),

I don't believe there's anything in my PCI updates which should have
changed the behaviour - they were touching mainly the scanning for
devices, and the way we write resources back into the hardware.  The
latter rarely happens on x86, except for cardbus devices.

I'm not suspecting the PCI in particular for the PCIC-bits, only
making X and the Radeon work again. But here you are:

I'm not suspecting the PCI in particular for the PCIC-bits, only
making X and the Radeon work again. But here you are:

Something bad has happened to the Radeon driver in recent kernels.  I've seen
various reports with various syptoms and some suspicion has been directed at
the AGP changes.

But as far as I know nobody has actually got down and done the binary search

Something bad has happened to the Radeon driver in recent kernels.  I've seen

the AGP changes.

The AGP code enables my machine with 1xAGP, but under 2.4 with same X
version it will support 4x. I had a poke around in the Intel AGP code
and there doesn't seem to be a way to manually convinve the driver of
the truth :)

Just got my machine out and booted up, this time I did enable my
chipset into 4x AGP, instead of 1x as last night:

alexh@lapper ~ $ dmesg | grep -i agp

agpgart: Detected Intel i845 chipset

The best I've narrowed it down to is whatever makes 2.5.64-mm1 be
different from plain 2.5.64 and 2.5.64-mm2. In addition, I have one
more gripe, and this one is present in 2.4 too, but seems kernel
related:

When closing Gnome (Gnome 2.x, Gentoo), after the screen has been
"faded" by the logout applet, on the first keystroke or movement of
the mouse the machine will instantly cold start the machine.

Hello, Alexandre and other.
       This error is not mm specific.
This was brought with latest PnP changes.
As I've understood that latest PnP Layer activates all devices during layer
initialisation, but I don't know how it could be if we don't register
pnp_driver. With first look I didn't find this runpaths. I'll try to
review all changes.

PnP code currently assigns resources at init and then activates during driver
matching.

Hi Ruslan and others,

Yes, this is actually a glitch in the driver.  The bios has activated this
device at boot time and the driver tries to activate it again without
checking if it was active in the first place.

I'm going to do the following to correct this:
1.) Update this driver to use the new pnp code, the new code automatically
manages this.
2.) Change pnp_activate_dev so that it doesn't return an error if the device
is already active, instead have it silently stop.  This is a more logical
behavior because the device will function properly even if it was already
active.  I should probably do the same with pnp_disable_dev.

Regards,
Adam

So far so good. There are couple of non-critical things I noticed.

shpte really blew the doors off of pte_chains for my home box and
slightly more than halved pagetable space. It really helps keep things
from swapping, a good 4-6 MB of pte_chain + pagetable space. I wish for
it back relatively often.

OTOH objrmap appears to have blown page_*_rmap() functions off the
profiles on the execution time front.

This is really the only visible task scheduling pathology. The user
observable effect is that now transparent xterms "flash" when being
wiggled, where before they merely showed some refresh jitter. But it's
a vast net improvement; good work on mingo's part.

I've not been noticing the more refined aspects of io scheduling.
Basically once deadline-iosched hit, my home machine was very happy,
and the gains after mostly slight. There's some of app startup time
that appears to have been trimmed down that may have come from this.
I noticed it while booting but by and large I don't spawn new large
tasks regularly, so it sort of doesn't do as much for me as others.
It could also be due to the prefaulting or a combined effect.

This is really the only visible task scheduling pathology. The user
observable effect is that now transparent xterms "flash" when being
wiggled, where before they merely showed some refresh jitter. But it's
a vast net improvement; good work on mingo's part.

I've not been noticing the more refined aspects of io scheduling.
Basically once deadline-iosched hit, my home machine was very happy,
and the gains after mostly slight. There's some of app startup time
that appears to have been trimmed down that may have come from this.
I noticed it while booting but by and large I don't spawn new large
tasks regularly, so it sort of doesn't do as much for me as others.
It could also be due to the prefaulting or a combined effect.
