Description
This year, the Maintainer's and Kernel Summit will be at the Corinthia Hotel in Lisbon, Portugal, September 9th -- 12th. The Kernel Summit will be held as a track during the Linux Plumbers Conference September 9th -- 11th. The Maintainer's Summit will be held afterwards, on September 12th. As in previous years, the "Maintainer's Summit" is an invite-only, half-day event, where the primary focus will be process issues around Linux Kernel Development.
The "Kernel Summit" is organized as a track which is run in parallel with the other tracks at the Linux Plumber's Conference (LPC), and is open to all registered attendees of LPC. The goal of the Kernel Summit track will be to provide a forum to discuss specific technical issues that would be easier to resolve in person than over e-mail.
We will reserving roughly some Kernel Summit slots for last-minute discussions that will be scheduled during the week, in an "unconference style". This allows ideas that come up in hallway discussions, and in the LPC miniconferences, to be given
scheduled, dedicated times for discussion.
Hello.
I would like to give a talk about KVA allocator in the kernel and about
improvements i have done.
See below the presentation:

Thank you in advance!

Implementing safety-critical systems usually requires adhering to meticulously defined development processes that specify how code is supposed to be developed, integrated and reviewed, driven by the assumption that a disciplined approach leads to reliably high quality. While known to produce code that can satisfy the highest quality standards, Linux kernel development does not follow such...
In the linux kernel, most operations affecting a process's address space are protected by by mmap_sem (a per-process read-write semaphore).
This simple design is increasingly a problem for multi-threaded applications, and often causes threads that operate on separate parts of their address space to end up blocking on each other due to false sharing issues - mmap_sem only supports locking the...
Big systems are becoming more common these days. Having thousands of CPUs is
no more a dream and some applications are attempting to spread over all
these CPUs by creating threads.
This leads to contention on the mm->mmap_sem which is protecting the memory
layout shared by these threads.
There were multiple attempts to get rid of the mmap_sem's contention or the
mmap_sem itself, Speculative...
What could be more fun than talking about kernel documentation? Things we
could get into:
-
The state of the RST transition, what remains to be done, whether it's
all just useless churn that makes the documentation worse, etc. -
Things we'd like to improve in the documentation toolchain.
-
Overall organization of Documentation/ and moving docs when the need
arises. It seems I end...
The ABI between Linux and user software mostly sits at the user/privileged boundary, although many architectures extend this with a small amount of special-case code that sits in userspace, such as in special pages or shared libraries (vDSOs) mapped into each user process [1] that user code can call into.
The reasons for this are a bit arbitrary: system interface libraries such as glibc and...
KUnit is a new lightweight unit testing and mocking framework for the Linux kernel. Unlike Autotest and kselftest, KUnit is a true unit testing framework; it does not require installing the kernel on a test machine or in a VM (however, KUnit still allows you to run tests on test machines or in VMs if you want) and does not require...
