Birds of a Feather
This is to discuss the idea of limiting the VMAs to growing, reference counting and how locking could be handled for RCU safe VMA lookups.
This BoF is to discuss pros and cons of various approaches to avoid
performance issues resulting from excess modifications of the direct
map, what APIs should these approaches provide and what is the best way
to integrate them with the existing allocators.
Let's continue the platform specification discussion in the BoF.
Some of the things that needs further discussion:
• Mandating Compatibility and branding of the RISC-V platforms
• Do we mark various combinations deprecated or not ?
Further discussion on the proposed user interrupts feature
his is a gathering to discuss Linux-kernel RCU internals.
The exact topics depend on all of you, the attendees. In 2018, the focus was entirely on the interaction between RCU and the -rt tree. In 2019, the main gathering had me developing a trivial implementation of RCU on a whiteboard, coding-interview style, complete with immediate feedback on the inevitable bugs. In 2021, this was a Q&A...
HMM (heterogenous memory management) was first merged in the Linux kernel in 2017 and has since been adopted by several device drivers. As it integrates the device drivers more closely with the core kernel's virtual memory management, more kernel subsystems are starting to get involved in related code reviews and take notice, e.g. file systems and page cache. As a consequence, we need to...
