linux-mm-basics: increase stack size

2019-03-28T10:00:00Z

The example shows a prefaulted stack size of 8KB, which is pretty small. Set it up to 64KB, which is a bit mor realistic. Also, remove the pointless "return" at the end of that function. Signed-off-by: John Ogness

kernel-tracing: KPROBES -> kprobes

2019-03-28T09:49:20Z

Why is kprobes in all caps? Change it. Signed-off-by: John Ogness

kernel-tracing: fixup denglish, add perf probe, tracing_on

2019-03-28T09:43:47Z

There were some german and german-like words lingering. Fix these to proper english. Show the use of "perf probe" for adding kprobes and uprobes. Move the tracing_on()/tracing_off() slide next to the trace_printk(). It makes more sense there since we are talking about writing kernel code for tracing. Signed-off-by: John Ogness

kernel/dts: fix name of dtsi file

2019-03-22T14:39:40Z

The dtsi file is called mynode.dtsi, but the my.dts includes my.dtsi which doesn't exist. Fix it. Signed-off-by: Kurt Kanzenbach

kernel-debugging: lots of minor fixups discovered during training

2019-02-28T14:45:50Z

- update dynamic printk format - update addr2line for kernels by using script - update qemu lines for vexpress - add note about kaslr with qemu gdbserver - use uart0 for console and uart1 for kgdb - use 127.0.0.1 instead of localhost (otherwise qemu and gdb get confused about IPv4 or IPv6) Signed-off-by: John Ogness

linux-mm-basics: show the ulimit -s help

2019-02-28T14:43:17Z

The stack size is also an important parameter for memory. Show it as well. Signed-off-by: John Ogness

kernel/tracing: removed double named section tracers

2019-02-28T10:58:41Z

There are two sections named tracers. Probably a copy and paste error. Fix it. Signed-off-by: Kurt Kanzenbach

fix various typos and wrong commands in slides

2019-02-07T16:03:50Z

Fixes for: - missing variable definition in Makefile - wrong serial device in kernel parameters - missing trace-cmd subcmd and wrong parameter (sched_switch is an event, not a plugin) - missing #include in example code - fix copy&paste leftover Signed-off-by: Holger Dengler Reviewed-by: Kurt Kanzenbach

add klist slides

very basic version of slides for kernel lists Signed-off-by: Manuel Traut

Device Tree: initial version

2019-01-28T18:51:21Z

This is the initial version of a Device Tree Presentation. The Presentation includes Background, Scope and Advantages of Device Tree usage as well as a short explanation of the Syntax and Usage. It ends with information about current developments and references to further information. Also an excercise for the attendees is defined. Signed-off-by: Manuel Traut
