[Bradley Chapman]

Mr. Morton,

This patch: +drm-agp-module-dependency-fix.patch

has broken the radeon DRM driver under 2.6.0-test9-mm2. Enclosed is an e-mail I
sent to the dri-devel sourceforge list:

<snip>

I'm having problems using te DRI radeon driver in the 2.6.0-test9-mm2
kernel tree. When X is started, the kernel outputs these messages:

[drm:radeon_cp_init] *ERROR* radeon_cp_init called without lock held
[drm:radeon_unlock] *ERROR* Process 1083 using kernel context 0

The driver did not do this under 2.6.0-test9-mm1.

Interesting parts of dmesg (under 2.6.0-test9-mm2):

Linux agpgart interface v0.100 (c) Dave Jones
agpgart: Detected an Intel i845 Chipset.
agpgart: Maximum main memory to use for agp memory: 439M
agpgart: AGP aperture is 64M @ 0xec000000
[drm] Initialized radeon 1.9.0 20020828 on minor 0

I am using XFree86-4.3.0-42 from Fedora Core.

</snip>

Diffing the drivers/char/drm trees produces this, which I assume is the patch
you applied:

I've had some responses from dri-devel so far, but right now I'm running
2.6.0-test9-mm1, which works perfectly fine.

What now?

TIA

I've heard that it's because of the locking in the tty layer.

Unlikely to be an IO scheduler change.

Switching from X to console or back can cause high CPU scheduling
latencies. I haven't tried to discover why.

Re: 2.6.0-test9-mm2

[Daniel Drake]

I've been getting a couple of audio skips with 2.6.0-test9-mm2. Haven't heard a 
skip since test4 or so, so I'm assuming this is a result of the IO scheduler tweaks.

Here's how I can produce a skip:
Running X, general usage (e.g. couple of xterms, an emacs, maybe a 
mozilla-thunderbird)
I switch to the first virtual console with Ctrl+Alt+F1. I then switch back to X 
with Alt+F7. As X is redrawing the screen, the audio skips once.
This happens most of the time, but its easier to reproduce when i am compiling 
something, and also when I cycle through the virtual consoles before switching 
back to X.

System:
AMD XP2600+
nForce2 motherboard
512MB RAM
nvidia GeForce4 Ti4800

Audio being played through the intel8x0 alsa module.
I use the nvidia binary graphics driver with X.

XMMS 1.2.8
XFree 4.3.0

If theres any other info I can give, please tell me and I'll do my best to help out.

I tried the force driver on my nForce2 machine and although it mostly works 
(DHCP works, I can receive mail over the interface, etc..) it doesn't seem to 
handle really bulky loads. For example, I'm running an FTP server on the 
machine (proftpd), and although FTP navigation works just fine, transferring 
large files just causes the transfer to hang indefinitely.

Removing the driver and using NVIDIA's proprietary driver allows me to 
transfer via FTP properly.

FWIW, it compiles nicely, runs nicely and as with -mm1, I haven't
really found problems I can't blame myself for (seems to go bonk from
time to time with vmware modules, likewise with the orinoco-usb
driver, but without those it is very nice :)

- Various random fixes.  Maybe about half of these are 2.6.0-worthy.

- Some improvements to the anticipatory IO scheduler and more readahead
  tweaks should help some of those database benchmarks.

  The anticipatory scheduler is still a bit behind the deadline scheduler
  in these random seeky loads - it most likely always will be.

- "A new driver for the ethernet interface of the NVIDIA nForce chipset,
  licensed under GPL."

  Testing of this would be appreciated.  Send any reports to linux-kernel
