A brief look at sort -k 3 /proc/kallsyms makes it clear that the kernel symbol table is stuffed full of duplicate names with distinct addresses. These are all symbols in distinct translation units, so it would presumably be nice for tracers to be able to distinguish between them (e.g. to trace only specific functions known to be called from TUs of interest). Right now, for symbols in the core...
The Btrfs developers are planning on attending LPC and would like to have a dedicated BoF so we can sit down and do some planning and have some discussions.
The current userspace API for brightness control offered by
/sys/class/backlight devices has various problems:
-
There is no way to map the backlight device to a specific
display-output / panel -
On x86 there can be multiple firmware + direct-hw-access
methods for controlling the backlight and the kernel may
register multiple backlight-devices based on this which are
all...
In the last few years, the open source host firmware communities made great progress on the coreboot/LinuxBoot stack. Now it is ready for prime time. With this stack, Linux developers gain total control of host firmware (aka. BIOS): host firmware bugs can be tackled as easily as Linux bugs; host firmware can be developed together with kernel/tools to enable new hardware technologies and/or to...
In 2021, at the Plumbers VFIO/IOMMU/PCI micro-conference, we introduced device attestation of PCI devices via CMA/SPDM (Component Measurement and Authentication / Security Protocol and Data Model). However, device attestation and SPDM is not...
This is a follow-up BoF for the "Linux Kernel Scheduling and Split LLC architectures" topic that will be presented at the "Real Time and Scheduling Microconference.
This BoF is for exploring the solution space and to discuss the way forward.
As every year, we are going to have an Android BoF after the Android MC in order to allow more time for free-form discussion of the various topics presented during the Android MC.
Io_uring command is a new async-ioctl-like facility to attach io_uring capabilities to any arbitrary command implemented by the underlying provider (driver, filesystem, etc.). The first use case of the construct is to implement a new passthrough path to NVMe. This path guarantees both availability and scalability. It helps both the early adopters of NVMe and the kernel community as emerging...
When a process wants to ptrace a child without imposing unacceptable signal-handling latencies, it has to waitpid() on it, so that when a signal is received it is immediately detected and can be dispatched to the tracee. But if that process also wants to do anything else at all, it cannot be stuck in waitpid: it must be able to go off and do that other work. So it must use waitpid(WNOHANG). To...
Google and Meta are both investing in frameworks for implementing pluggable schedulers, ghOSt and SCX respectively. This BoF will discuss both frameworks, and how we can best tackle the scheduling problems that the frameworks are trying to solve.
We'll talk about all stuff systemdee.
