The Linux 2.6 Kernel (features and installing)
<Previous Page 2 of 6 next>
Better support for embedded systems,
Linux is used for many embedded systems like PDA's
In the new kernel much of the uCLinux project is now embedded in the mainstream kernel. There is support for new generation processors that are used for this embedded systems like the, Motorola's embedded m68k processors, Hitachi 's H8/300 series and the NEC v850 processor
Increased support for Multi processor systems
Another fundamental change in Linux 2.6 Kernel is Linux's new support for NUMA server. This makes the new Linux 2.6 kernel a more effective kernel on larger and larger servers. NUMA ("Non-Uniform Memory Access") this is a gigantic improvement in comparison to the SMP technology and is provides more efficiency on multi processor systems.
Linux Hardware and Network Scalability
The scalability has improved enormously, here are some figures:
- the number of unique users and groups on a Linux system has grown from 65,000 to over 4 billion from 16 bit to 32 bit
- The number of PIDs (Process IDs) has grown from 32,000 to 1 billion
- Support for file systems up to 16TB on common hardware
- nodes were limited to 255 "major" devices and 255 "minor" devices of that type The new kernel supports 4095 major device types and a more than a million sub devices per type
