Announcement: RapidDisk (rxdsk) 1.1b Stable release, a new kind of Linux RAM Disk
I am writing to announce the update release of my Linux RAM disk kernel module RapidDisk (rxdsk). It is currently at a stable 1.1b release with added support for dynamic resizing of attached rxdsk volumes. More information can be found at rxdsk.petroskoutoupis.com.
Note - So far this has only been tested and seen as fully functional on the 2.6.32 and 2.6.35 kernels. There is a plan to upmerge to the 3.x line by the next official release.
A bit of a background...
Unlike brd or zram all attached RAM disk are populated on-the-fly with any user defined size and not during the module’s insertion (i.e. typically system bootup) with a fixed size. When you attach a new RAM disk, you can define sizes as little as 16 Mbytes and in theory as large as 1 TByte and possibly above and it is designed to allocate new kernel pages as needed; so it won’t steal all memory when the RAM disk is created.
For details on contributing, please reference my contribution page. At the moment, I am really looking for assistance on the performance benchmarking. If you have a 64-bit Linux OS installed on physical 64-bit hardware, I would love to see the results of various benchmarking tests using common benchmarking tools.
