Minidump for Debugging End User Device Crashes

Explore the efficient minidump mechanism for debugging end user device crashes in this Linux Plumbers Conference talk. Learn how Qualcomm devices in engineering mode generate full system RAM dumps for postmortem debugging, and discover the advantages of collecting minimal required data from RAM for end user devices. Understand the process of selecting specific snippets for inclusion in RAM dumps, addressing hardware and software bugs in System on Chip (SoC) or subsystems. Gain insights into the existing upstream support for Qualcomm remote processor regions and the ongoing efforts to upstream the kernel driver for collecting kernel regions. Examine the potential for making the minidump solution more generic to accommodate other SOC vendors' needs and explore possible extensions to the current solution.
