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: Failing to install linux 3.10.10 on Intel xeon E5-2665
Hi,
The exact boot error message is
{1}[Hardware Error]: Hardware error from APEI Generic Hardware error
source: 32993
In the configuration file I selected option xeon.
I am new to kernel updates and need to do this on an ASAP basis, please
tell me how to install the kernel.
Also the newer 3.10.12 gives with the same error while booting.
Thanks
Rakhi

Failing to install linux 3.10.10 on Intel xeon E5-2665
Dear all, I am trying to install linux 3.10.10 using Arch Linux on a xeon machine with following configuration. cpu family : 6 model : 45 model name : Intel(R) Xeon(R) CPU E5-2665 0 @ 2.40GHz It gives a error at boot time APEI Generic Hardware error source: 32993. For booting x86_64 kernel there is no such error for i386. Please advice, actually I need to access the uncore performance counters that are available only using latest linux kernel.
