During a rebuild of all packages in sid, your package failed to build on i386.

Hi Reinhard,

according to:
| kibi@becky:~/lcd4linux-0.10.1~rc2$ rgrep rdtscl /usr/include 
| /usr/include/asm-x86_64/msr.h:#define rdtscl(low) \
| /usr/include/asm-x86_64/msr.h:#define rdtscll(val) do { \

I guess that you want either check for the presence of asm-x86_64/msr.h
(easy way) or keep on using asm/msr.h and add a code snippet to find out
whether rdtscl() is really available.

Cheers,

I took a look at this; here is my analysis:

lcd4linux' configure checks for the presence of /usr/include/asm/msr.h,
which is on your buildd. that file contains on my system this:

#ifndef __ASM_STUB_MSR_H
#define __ASM_STUB_MSR_H
# if defined __x86_64__
#  include <asm-x86_64/msr.h>
# elif defined __i386__
#  include <asm-i386/msr.h>
# else
#  warning This machine appears to be neither x86_64 nor i386.
# endif

I can only conclude that you build defines the macro '__x86_64__'
confuses lcd4linux. Which is of course an important bug, but in no way
release critical, IMO.

Do you run sbuild with 'linux32' prefixed, so that tools like 'uname -m'
don't report x86_64?

Yes, I do.

I tried to reproduce this locally (x86 laptop), and it fails to build in
the same way. So re-bumping severity.

Not a real hint, but this has been reported in debian as well:

rdtscl is not defined anywhere except in /usr/include/asm-x86_64/msr.h.

I would have expected it to be defined on i386 when asm/msr.h is included.

rdtscl was removed as linux does not longer assume that it is able to
ask the TSC themself. Also it is unsafe to access the TSC from
userspace. I doubt that it is a bug at all in the kernel. Userspace
should use gettimeofday.

If you really think this is wrong, ask upstream yourself.

This is great news, Robert! Very much appreciated.

Can you perhaps send me the patch, as soon as Michael has applied it?
Or do you have the patch perhaps already applied to your ebuild?

Again, thanks for keeping me updated!

The change is in trunk [1], and as Michael writes he wants some  
reports before
applying it to the stable branch. I didn't test it or include it in
Gentoo yet as I'm on vacation (no LCDs here!) till tomorrow.

If you can test it earlier, let me know. Otherwise you'll hear from
me later this week.

Thanks,
Robert

I couldn't test it any further than compiling as only some drivers use 
the code, none of which I own a display for. Please refer to the thread 
for a list [1].

I'll attach the patch I tested with for you.

Regards,

Robert

Anything speaking against this patch, as we're including it in out 
ebuild now.

I'm currently this week on a conference. I will test and upload the
patch after I return home. Thanks for reporting back!

Subject: New Debian Packages need testing

Date: Thu, 10 Jan 2008 11:06:05 +0100

Hey LCD4Linux fans,

I finally got around to apply Michael's rdtsc fix for the debian
package. Unfortunately, after my notebook upgrade, my usb lcd device
stopped working, I assume it is not the device's fault, but something in
my 2.6.22 kernel. Anyway, I cannot really test the package, so I
uploaded it to http://siretart.tauware.de/upload-queue first.

Could please someone test that package and mail success or error reports
to 436332@bugs.debian.org? Thanks a lot in advance!
