Linux Kernel Versions An overview of the most important changes to the respective versions of the core Linux Kernel Versions - Thomas-Krenn-Wiki The Linux core is in a constant state of development and expansion. This article will provide an overview of the most important changes to the respective versions of the core. Linux Kernel 5.x Kernel 5.4 Kernel 5.3 Kernel 5.2 Kernel 5.1 Kernel 5.0 Linux..
The block I/O layer, part 4 - The multi-queue interface The block I/O layer, part 4 - The multi-queue interface
2022. 11. 19. ◈ 출처: http://ari-ava.blogspot.com/2014/07/opw-linux-block-io-layer-part-4-multi.html So, a couple of weeks ago I performed some first tests on the prototype driver using a simulated device created with the null_blk device driver. Such tests, and the following profiling, highlighted some locking issues due to contention on an internal lock kept by the frontend driver; more in detail, such a lock ..
The block I/O layer, part 3 - The make request interface The block I/O layer, part 3 - The make request interface
2022. 11. 19. ◈ 출처: http://ari-ava.blogspot.com/2014/07/opw-linux-block-io-layer-part-3-make.html During the past weeks, I have been learning about profiling an operating system running in a virtual machine, since I have been needing to examine the driver I am working on to locate bottlenecks and work out lock contention issues. My OPW mentor has suggested that I get to grips with some popular profiling tools..

2022. 11. 19. ◈ 출처: http://ari-ava.blogspot.com/2014/06/opw-linux-block-io-layer-part-2-request.html Following the many directives and suggestions given by my OPW mentor, I have been implementing the tiniest and simplest block I/O driver, whose multi-queue implementation just fills I/O request structures with available information about the CPU core the process has been issuing I/O from; this is proving very ..

2022. 11. 19. ◈ 출처: http://ari-ava.blogspot.com/2014/06/opw-linux-block-io-layer-part-1-base.html So, during the last few weeks I have been studying and tracing the block I/O layer of the Linux kernel, with the aim of getting a clearer view of how it works. A fellow student from the University of Modena and Reggio Emilia thought I might write a blog post on that. My very patient OPW mentor approved the topic ..
