Re: current state of nvidia quadro 140m and tuxonice

Hi,

I have migrated to a new laptop with nvidia quadro board:

01:00.0 VGA compatible controller: nVidia Corporation Quadro FX 570M 
(rev a1)

Unfortunately recent tuxonice does not resume. Switching to X or 
starting a new X server locks the machine. This is a soft lockup since 
powr button or crtl-alt-del starts the reboot process. I think it can 
successfully unmount the filesystems but halt/reboot fails. I have 
collected some logs, I hope this helps:

There's a claim on NVNews.net that says it might be related to GPU shared
memory- are we perhaps doing any optimizations in that region somehow?

Is there anything new at splashy. I did not find anything
in the web and on tuxonice.net

2.6.27 git tree regenerated.

Hi all.

I had some problems with the 2.6.27 tree on kernel.org, and have
therefore just regenerated it. If people who are pulling from it have
problems, you may need to do a fresh pull too. Sorry for any
inconvenience this causes.

about suspend2 's corruption problems in 2.4 kernel

Hi Negil, 

In our main page , I saw this message , 
"Current Versions
Here are the latest patches against 2.6 kernel series. 2.4 patches are currently 
unavailable due to reports of corruption problems with the most recent 2.4 kernels." 

about the corruption problems report with most recent 2.4 , 
would you mind please giving me detailed info ? for example , user's bugs report or developer's ideas ?  
I dived into TuxOnIce's bug zillia and archieved mailing list (user and development) ,but unfortunately I
find nothing . 
In my mind , I feel that this sentense will cause everyone confused , 
1, what is the recent kernel ?  You mean that 2.4.36.8 or other version , I feel that you'd better giving us
detailed version number. 
2, should give us a link in which user reports this bug and what he has done and how he has done. 
    Different users have their own application , maybe it is not affected for others.

 
thanks for your reply , kindly hope your more info. 

 
By the way , now I want to port 2.4.21 into mips architecture . By searching our mailing list ,
I found that it seems that someone has began to do such work ,but don't post related patch , 
Do you tell us the latest news about porting 2.6 or 2.4 series into MIPS architecture ? thanks very much!  
Do you any plan to port TuxOnIce to MIPS architecture ? 

 
Following is some messages in our mailing list,

Suspend2’s patch on ARM architecture on 2005.11.14 
http://lists.tuxonice.net/lurker/message/20051114.094040.11261d0e.en.html#suspend2-devel

In this message , I find this info:  
“Hi Hiroki. 

Thanks for sending this. I've just released rc10, and will incorporate 
your patch into the next release. 

Regards, 

Nigel”

But in the latest patch , why I didn’t find ARM words , 

One user want to port suspend2 to mips architecture ,and the reply of author of suspend2 :
http://lists.tuxonice.net/lurker/message/20060215.225134.b3b5ed05.en.html

One baby has began to do such work , it seems that he has finished this work that he can suspend current data
into usb harddisk : 
But can’t hibernate into usb flash: 
http://lists.tuxonice.net/lurker/message/20070124.195330.87415b0d.en.html

Another baby want to port suspend2 to MIPS architecture , but don’t know what exactly he should do :
http://lists.tuxonice.net/lurker/message/20070705.104938.21d208d1.en.html
http://lists.tuxonice.net/lurker/message/20070705.110629.a1147138.en.html

The third fellow has claimed that he has ported swsusp to mips almost , but still has problem :

Tuxonice for 2.6.27

Hi,

is there a version of tuxonice for kernel 2.6.27? The latest I see on
tuxonice.net is 3rc7a for 2.6.26 (which works great!).

Regards,
Ulrich

UUID= notation

Hello.
What is current status of resume=UUID=foo notation? First, I receive "No
matching enabled allocator found. Resuming disabled.". Should it be
resume=swap:UUID=foo or what? Second, will UUID be preserved after
suspend? What if I cancel a resume and do mkswap?

safe resuming: automatically invalidating an outdated hibernate snapshot

Cc to linux-kernel: This is mainly for tuxonice, but it might also be relevant 
for other hibernate implementations. Maybe some general mechanism for 
checking whether an on disk snapshot of the system is current would be good - 
as also the resume parameter could be missing or wrong or whatnot.

Hi!

Is there a way to automatically invalidate the tuxonice snapshot when a non 
tuxonice kernel is booted accidentally? I.e. could tuxonice recognize when 
the swap partition has been accessed *after* the snapshot has been written?

It happened here several times that someone booted the wrong kernel and then 
someone else booted the right one again. TuxOnIce would then resume from a 
snapshot that it not up-to-date anymore. This leads to filesystem breakage as 
the filesystem slab objects and other in memory structures would not 
represent the current state of the filesystem on disk. xfs_repair did a 
marvellous job on these occassions and I already changed menu.lst to hide the 
GRUB boot menu by default, but it would be better if this case of  
maloperation can be intercepted.

Ciao,
