Efficiency[edit] The specific dynamic memory allocation algorithm implemented can impact performance significantly. Another concept added to the API —during Linux 3.5[132] and libdrm 2.4.36[133] releases— were generic object properties, a method to add generic values to any KMS object.

Verification of Device Drivers[edit] There are two challenges that limit testing the device drivers. Because drivers require low-level access to hardware functions in order to operate, drivers typically operate in a highly privileged environment and can cause system operational issues if something goes wrong. KMS device model[edit] KMS models and manages the output devices as a series of abstract hardware blocks commonly found on the display output pipeline of a display controller. have a peek at these guys Current memory architectures are very complex and usually involve various levels of caches for the system memory and sometimes for the video memory too.

The lowest average instruction path length required to allocate a single memory slot was 52 (as measured with an instruction level profiler on a variety of software).[2] Implementations[edit] Since the precise Section 2.5: Dynamic Storage Allocation, pp.435–456.
