David Mandala, Manager of the ARM Team at Canonical talks about the status of Ubuntu Linux on ARM Laptops and Servers, and about their plans for Ubuntu on ARM until 2014 and beyond. Who wouldn't want to buy an awesome $199 ARM Powered Ultrabook, 13.3" screen, ARM Cortex-A9 1.5Ghz TI OMAP4460 or 1.8Ghz TI OMAP4470, thinner, lighter than Intel Ultrabooks, 2x longer battery life on a smaller thinner battery (10x with the sunlight readable Pixel Qi), 1GB or 2GB RAM for full speed Chrome and Firefox web browser speeds?
Talking about the status of Ubuntu on TI OMAP3 (beagleboard), OMAP4 (pandaboard), Marvell, Freescale, Calxeda, plans for Quad-core ARM Cortex-A9 optimizations by Ubuntu 12.10, ARM Cortex-A15, ARM Cortex-A7, ARMv8 64bit, the imminent inclusion of full hard-float optimization in Ubuntu 12.4 on ARM:
With Ubuntu 12.04 on ARM there is also hard-float support (ARMhf), as previously talked about on Phoronix, and this will mean a huge performance boost for many workloads. Mandala said the performance boost they are seeing is between 5% and 30% improvement for floating-point operations. Also benefiting greatly for end-users is improved font-rendering, web-page scrolling, and other operations from this ARM hardfp support. Other code is also benefiting due to better use of the stack calling convention.
