Kmemdump Proposed For The Linux Kernel To Help With Memory Dumping & Debugging
Eugen Hristev of Linaro sent out a 'request for comments' patch series today proposing kmemdump for the Linux kernel as a new means to assist in debugging driver/system problems by making it easier to dump memory for specific areas/regions.
Eugen Hristev of Linaro sent out a "request for comments" patch series today proposing kmemdump for the Linux kernel as a new means to assist in debugging driver/system problems by making it easier to dump memory for specific areas/regions. Kmemdump is infrastructure that allows kernel drivers to register specific chunks of memory and those flagged areas can be easily dumped in case of system problems or other debugging purposes. With appropriate system capabilities and hardware, it could be possible to save those kmemdump-monitored regions in case the kernel becomes frozen/crashed or other problematic state and just keeping track of those specific memory areas.
