Does CPU set the Referenced bit Memory Management
Hi, I want to understand the mechanism by which linux marks a page as referenced. According to the documentation in Understanding The Linux Virtual Memory Manager Figure 11.6 and Table 3.1, there is a bit PG_referenced that can be queried to test if the page was accessed. I want to ask if the CPU can/does set that bit. Also, is this bit set on a LLC miss or on a TLB access? Thanks a lot. Please tell me if there are some manuals/other forums I could refer to for this question. -- Rakhi Hemani Phd Scholar Roll Number PhD1207 ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies

Re: Get Mount target from path
On Wed, 04 Feb 2015 16:23:26 +0900, manty kuma said: I would like to know the mount target for a given directory. In kernel, is there an API to get the information? Explain what problem you're trying to solve. Your example: /system/bin is a directory its mount partition is /system. isn't very clear on what you mean. Do you mean I did a mount /dev/foox4 /mnt/wombats and now I want to find /dev/foox4, or did you mean given a pathname or inode, what filesystem is it on? (Bonus points for explaining what your solution should do with bind mounts and overlayfs and other exotic stuff like that) pgpghb88oxg5W.pgp Description: PGP signature ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
Re: eudyptula response time
does anyone have an idea when is the response time for task 08? When I submitted last december, I was 115th in the queue. I don't want to resubmit again fearing that I will be bumped up into the end. Dean I was also thinking about asking about my current queue-status (different task), but oh well. It would be a nice feature if automated. Anyways: you're not alone waiting ;) martin After asking something similar a few days ago, it was brought to light that responses will be slow for the moment. I'm quoting what Giedrius told me then: Taken from December 2014 challenge status report: But note, for everyone, responses for the next month are going to be very limited. So relax, go read a good book, take a bike ride, enjoy the lovely weather outside, don't worry about kernel programming challenges, they aren't going anywhere, and as this isn't costing you anything, there's nothing you can do about it. Also don't resubmit your solution because that will put you at the end of the queue.
