Sometimes, applications may not run well, or they could even crash. When such issues occur, it is useful to have a consistent, reproducible method of triggering the problem, so that developers can have a reliable way and sufficient data to troubleshoot the issues and produce a fix. In the software world, the GNU Debugger (gdb) ...
These days, the internal workings of Linux applications involve many different moving parts. Sometimes, it can be rather difficult to debug them when things go wrong or run slower than expected. Tracing an application’s execution is one way of understanding potential issues without diving into the source code. To this end, we wrote an app ...
Slow applications are never fun. But not knowing why an application is not behaving correctly can be even more frustrating. A well-designed system that can diagnose performance or startup issues and inform the user about the problem goes a long way toward mitigating the frustration, and may even help resolve the root cause altogether. Bac ...
In my previous two articles, ACPI AML Debugger in Ubuntu 18.04 & Debug AML (DSD & SSDT) with ACPICA Utilities, I discussed techniques for AML debugging; however the ACPI specification includes many other important tables. Firmware Test Suite (FWTS) is a test suite (as the name indicates) that can play a big role in debugging ...
Using acpidbg on Ubuntu 18.04 x64 can be quite handy; however, the Linux kernel with ACPI_DEBUGGER is not always available, such as on Ubuntu for ARM. In such cases, acpica also provides a set of utilities, named acpica-tools, for ACPI debugging. Installation Installing acpica-tools is as easy as the following command: The latest source c ...
“All my centurions develop using snaps.” Julius Caesar By and large, software development can be an enjoyable process. Until you hit the first error, that is. At that point, you want to get past the stumbling blocks as quickly as possible and resume building your apps. A robust, flexible development framework can make a big ...
ACPICA is an open-source project that provides an operating system (OS)-independent reference implementation. It also contains a list of utilities such as ASL compiler (iasl), acpiexec (an AML emulator). However, AML debugging on Linux in run-time wasn’t provided in ACPICA until Linux Kernel 4.13. Enabling AML Debugging The aml-debugger.t ...
