CLONE_VM Example

-
This post we will write a code, which will give us an observation what changes when CLONE_VM is added and when it is removed.

Code:


Output:

Notes:

 1. Modifications to Local variable 'buf' by child reflected when CLONE_VM is added
2. Modifications to Global variable 'global_value" by child reflected when CLONE_VM is added
3. Modifications to Heap variable 'heap' by child reflected when CLONE_VM is added.

Appending and Prepending in Yocto - +=, =+ vs .=, =.

-
Image
Bitbake provides two sets of appending and prepending operators. 1. +=, =+ 2. .= , =. For example, A = "hello" A += "world" C = "good" C =+ "bye" The value of A will be "hello world" and C will be "bye good" So, += is appending and =+ is for prepending. Note, that these operators include an additional space between each call When we don't need to add space, we can use .=, =. operators. These are mainly used to concatenate strings. When we use append, prepend, there will be no additional space added, you need to manually provide space. You can also remove values from the variable using 'remove'.

Linux driver example for Per CPU Variable

-
Image
Per CPU Variables is an interesting feature available from Linux Kernel Version 2.6 When you define a Per CPU Variable, each processor in the system will have its own copy of the variable, hence no locking is required and better performance is achieved. Header File: <linux/percpu.h> To create a Per CPU Variable at compile time, use the macro: DEFINE_PER_CPU(type, name); E.g. DEFINE_PER_CPU(int, counter); As linux kernel is preemptible, you must use get_cpu_var macro to access the current processor's copy of a given variable And finally call put_cpu_var macro after you have completed using it. You can access another processor's copy of the variable with: per_cpu(variable, int cpu_id); Example: Output:
