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-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 ..
리눅스커널(Linux Kernel)의 버전관리(Versioning)
2020. 10. 24. *원본 출처: cloudrain21.com/version-management-of-linux-kernel 리눅스커널(Linux Kernel)의 버전관리(Versioning) - Rain.i All about IT tech, especially database, cloud, linux, clustering. cloudrain21.com 오늘 나는 이 문서의 내용중에서 특히 기본적으로 알고 있어야할 Linux Kernel 의 Versioning 에 관해 요약해보려고 한다. Linux Kernel 의 버전 관리가 이전에 비해서 좀더 복잡해진 가운데, 릴리즈 주기가 약 3 개월 단위로 짧아진 것은 버전관리 Process 가 그만큼 효율적으로 잘 정립되어 있기 때문이 아닌가 싶다. 참고로, 포스팅을 하고 있는 2..
